Storing 3D grids in a georaster?

I have 3D gridded data, with 2 of the dimensions being X and Y (northing/easting, latitude/longitude, etc.) and the third dimension being either elevation or time. I am storing the third dimension as bands in the groraster. It's possible to map the X/Y dimensions to earth positions using the setModelSRID and setWorldFile methods, but what is the best way of associating the actual time or elevation dimension values with the georaster? Right now my georaster just has a bunch of bands, with no information stored indicating what (elevations or times) the bands refer to.
Thanks

MikeDW,
To indicate "what (elevations or times) the bands refer to", you may consider using the georaster's ID or the Object Layer's ID and/or "description". These are just string types which you can use to describe anything about the georaster. You can call the following procedures and functions:
SDO_GEOR.setID and SDO_GEOR.getID
SDO_GEOR.setLayerID and SDO_GEOR.getLayerID (with layer number 0 for the Object layer)
To associate the actual time or elevation dimension values, you may consider adding a new column in the same georaster table (or any other approach) to store the association (temporal and vertical referencing, in whatever your preferred formula). To access these dimensions, you need to translate your actual time or elevation into band (or layer) numbers and then query against the georaster object, or the reverse. For your reference, another thing you can consider for time is to leverage the simple TRS in GeoRaster by setting the begin and end time:
SDO_GEOR.setBeginDateTime and SDO_GEOR.getBeginDateTime
SDO_GEOR.setEndDateTime and SDO_GEOR.getEndDateTime

  • How to use ALV Grid?

    Hi,
    I am totally new to ALV Grids. Could you give a full example of creating a ALV Grid with 2 columns, thinking there is a internal table itab with itab-col1 & itab-col2. Please start from initialising variables and onwards.
    Thanks,
    Kishan

    Hi,
    Simple example of how to implement an ALV grid
    Note that this example uses table ZSFLIGHT. The table is equivalent to the table SFLIGHT.
    Steps:
    1.        Create an executable program (Report)
    2.        Create a screen (100) and place a custom container named ALV_CONTAINER on the screen
    3.        Create a Pushbutton. Give it the text Exit and the functioncode EXIT
    REPORT sapmz_hf_alv_grid .

    Allow the user to save and reuse the layout
    A button can be shown on the grid toolbar, allowing the user to save and reuse a layout. The button looks like this: 
    See also example in SAP standard program BCALV_GRID_09.
    To do this use the parameters IS_VARIANT and I_SAVE of the set_table_for_first_display method. Note that the IS_VARIANT
    parameter must have the structure DISVARIANT.
    The I_SAVE "Options for saving layouts" parameter can have the following values:
    ·        U Only user specific layouts can be saved
    ·        X Only global layouts can be saved
    ·        A Both user specific and global layouts can be saved
    ·        Space Layouts can not be saved
    Add the following code to the example:
    FORM load_data_into_grid.

    Examples of fields in structure lvc_s_layo:
    GRID_TITLE Setting the title of the grid
    SEL_MODE. Selection mode, determines how rows can be selected. Can have the following values:
    ·        A Multiple columns, multiple rows with selection buttons.
    ·        B Simple selection, listbox, Single row/column
    ·        C Multiple rows without buttons
    ·        D Multiple rows with buttons and select all ICON
    Setting and getting selected rows (Columns) and read line contents
    You can read which rows of the grid that has been selected, and dynamic select rows of the grid using methods get_selected_rows
    and set_selected_rows. There are similar methods for columns.
    Note that the grid table always has the rows in the same sequence as displayed in the grid, thus you can use the index of the selected
    row(s) to read the information in the rows from the table. In the examples below the grid table is named gi_sflight.
    Data declaration:
    DATA:
    Internal table for indexes of selected rows
    gi_index_rows TYPE lvc_t_row,
    Information about 1 row
    g_selected_row LIKE lvc_s_row.

    CALL METHOD go_grid->get_selected_rows
    IMPORTING
    et_index_rows = gi_index_rows.

  • ALV GRID Using oo abap example

    Hi Friends,
    I am new to oo abap, Can any one give me a basic example how i can create alv grid in oo abap.
    regards,
    DVNS

    HI,
    Programming for ALV grid display using the classes involves  creation of a screen and calling it for display.
    Since there has to be a linking between the program and the screen we have created , this comes in the form of a container. We use two important classes during the programming for displaying ALV grid, CL_GUI_ALV_GRID and CL_GUI_CUSTOM_CONTAINER.
    Steps To Use ALV Grid in a Program
    1. Declare reference variables for,
           Container (class CL_GUI_CUSTOM_CONTAINER) and
           Grid (class CL_GUI_ALV_GRID)
    Example
    DATA: grid  TYPE REF TO cl_gui_alv_grid,
                custom_container  TYPE REF TO cl_gui_custom_container
    2. Create Standard Screen and a container on that screen  and give a name to that container ( Use custom control button from tool bar) . This name will be used to link the container we have created on the screen with the object reference of class CL_GUI_CUSTOM_CONTAINER, which we have declared in the first step
    3. Call the screen which has been created
    4. Instantiate the container control and the ALV Grid Control in PBO of the screen.
    Example
    IF custom_container IS INITIAL.
      CREATE OBJECT custom_container
             EXPORTING
            CONTAINER_NAME = ‘MY_CONTAINER'.
    CREATE OBJECT grid
           EXPORTING
           I_PARENT = custom_container.
    ENDIF
    5. For displaying the data, call the method set_table_for_first_display of object reference of CL_GUI_ALV_GRID.
    Example
    CALL METHOD grid->set_table_for_first_display
    EXPORTING
    I_BUFFER_ACTIVE               =
    I_BYPASSING_BUFFER            =
    I_CONSISTENCY_CHECK           =
    I_STRUCTURE_NAME              =
    IS_VARIANT                    =
    I_SAVE                        =
    I_DEFAULT                     =
    IS_LAYOUT                     =
    IS_PRINT                      =
    IT_SPECIAL_GROUPS             =
    IT_TOOLBAR_EXCLUDING          =
    IT_HYPERLINK                  =
    IT_ALV_GRAPHICS               =
    IT_EXCEPT_QINFO               =
    CHANGING
    IT_OUTTAB                     =
    IT_FIELDCATALOG               =
    IT_SORT                       =
    IT_FILTER                     =

    INVALID_PARAMETER_COMBINATION =
    PROGRAM_ERROR                 =
    TOO_MANY_LINES                =
    others                        =
    EXPLANATION OF SOME IMPORTANT PARAMETERS.
    I_BYPASSING_BUFFER & I_BUFFER_ACTIVE :
    When the program is run for the first time, the fields present in the output table and their positions are stored in a buffer.  So the buffer is taken as reference for the successive executions.  In order to bypass this buffer the above parameter values should be ‘X’ and  ‘ ‘(space)  respectively. If these values are not passed  to the function module, the changes made in the structure of the internal table will not be reflected in the output.
    I_STRUCTURE_NAME:
    If the structure of your output table corresponds to a structure stored in the Data Dictionary (DDIC), the ALV Grid Control can use this information to generate the field catalog automatically. Pass the table structure as parameter. In this case, all fields of this DDIC structure are displayed in the list.
    IS_VARIANT :
    It allows the user to save and reuse the layout. It is a structure of type DISVARIANT and contain the display variant name. It  facilitates pre-assignment for a layout, rather than displaying report and then choosing displaying variant.
    I_SAVE:
    This single character variable specifies whether the user specific display variants can be saved or not.
    The I_SAVE "Options for saving layouts" parameter can have the following values:
    U Only user specific layouts can be saved
    X Only global layouts can be saved
    A Both user specific and global layouts can be saved
    Space Layouts can not be saved
    IS_LAYOUT:
    This structure of type LVC_S_LAYO
    is used to control the layout of the ALV.  Two important fields are:
    GRID TITLE. : Title of grid
    ZEBRA : Alternate lines in list are displayed in different colors.
    IT_FIELDCATALOG:
    This internal table of type LVC_T_FCAT
    is used to specify the position of various fields in the report itab.
    There are three ways we can fill the field catalog table
    1. Automatically through data dictionary structure (DDIC). In this case we pass the table structure to I_STRUCTURE_NAME.
    2. Manually in ABAP program. Filling the internal table of type LVC_T_FCAT
    1.                  . With each row corresponding to each column of output table. Each row of this table will hold value like
    i). TABNAME & FIELDNAME specifies the reference fields for F1 help
    ii). CTABNAME & CFIELDNAME specifies the reference fields for currency formatting
    iii). QTABNAME & QFIELDNAME specifies the reference fields for quantity formatting
    iv). SELTEXT_L holds the long description of the field
    v).  SELTEXT_M holds the medium description of the field
    vi). SELTEXT_S holds the small description of the field
    vii). KEY specifies the Key field ( cannot be hidden )
    viii). OUTPUTLEN species the output length of the field
    ix). DO_SUM specifies that subtotal is required on this field
    x). NO_OUT specifies a hidden field
    3.  Semi-Automatically by combining the above 2 procedures.
    Call function Module REUSE_ALV_FIELDCATALOG_MERGE and pass DDIC
    structure or the output table to generate the field catalog.
    Add additional Rows or modify existing properties of the fields to be displayed.
    METHODS OF IMPLEMENTING SOME EXTRA FEATURES
    Set focus to the grid
    After CALL METHODgrid->set_table_for_first_display insert the following stament:
    CALL METHOD cl_gui_control=>set_focus EXPORTING control = grid
    Refresh grid display
    Use the grid method REFRESH_TABLE_DISPLAY
    Example:
    CALL METHOD grid->refresh_table_display.
    Set the title of the grid
    Fill the grid_title field of structure lvc_s_layo.
    DATA:
    gs_layout TYPE lvc_s_layo.
    gs_layout-grid_title = 'TITLE'.
    CALL METHOD go_grid->set_table_for_first_display
    EXPORTING i_structure_name = 'structure name'
    is_layout               = gs_layout
    CHANGING   it_outtab               = Output table.
    The structure lvc_s_layo contains fields for setting graphical properties, displaying exceptions, calculating totals and enabling specific interaction options
    Event Handling
    We can handle the events triggered by
    1. User defined Text Output
    2. Mouse-controlled Actions
    3. Self-defined and Standard Functions
    Steps for Event Handling
    1. Define a (local) class for event handling
    2. Define a method for each event you need to handle
    3. Implement your event handler methods.
    4. Create Object of the above class
    5. Link used events and event handler methods of the  receiver object and the grid
    object.
    Example program : Handling “Double Click” Event
    Step1.Define a class.
    class lcl_my_event_receiver definition.
    public section.
    methods:
    handle_double_click
    for event double_click of cl_gui_alv_grid.
    endclass.
    Step 2. Implement the class
    class lcl_my_event_receiver implementation.
    method handle_double_click.
    message i001(zz) with ' double click event - Triggerd '.
    endmethod.
    endclass.
    Step 3. Declare and create Object for the local class defined and implemented in steps 1 and 2 respectively
    o_receiver   TYPE REF TO lcl_my_event_receiver   (Declaration)
    create object o_receiver.                                            (Instantiation)
    Step 4. Link the method for handling the event with the grid object in the PBO of screen after instantiating the grid object
    set handler o_receiver->handle_double_click for grid.

  • Install grid control agent 10.2.0.5 on VM Server?

    Hi:
    I'm using Enterprise Manager Grid Control 10.2.0.5 with the Virtual Server extensions and it is working fine. However, I've noticed that my Virtual Server machine (dom0 -- not the guests) does not show as a host on my Targets tab.
    One drawback to this is that I've tried to import the templates that already exist in my Seed Pool into the Software Components tab of my Virtual Servers tab. It has an option to find a Host, but the only hosts lists are those that have Grid Control agents on them.
    Is this expected behavior?
    Would it be beneficial to install the Grid Control 10.2.0.5 agent on my VM Server 2.1.5 so that I can load the templates into the Software Components tab?

    pasinc wrote:
    Thanks. I do have all of the Templates under Resources in my Virtual Server Pool. However, none of them appear under the Software Components tab. Should they?Not necessarily.
    If not, what is the difference between the two? Why don't they appear as Software Components?Software Components = stored in the Grid Control Software Library
    Server Pool Resources = stored in the Server Pool's /OVS/seed_pool
    So, the Software Components shows you templates that have been stored in Grid Control and these templates can be deployed to any of your server pools (you can have multiple server pools). Once this happens, you'll see the template in both locations. It's a little counter-intuitive, I admit. If you're used to VM Manager, then the Server Pool Resources is the same as what you'd see in VM Manager. Then Grid Control adds the central Software Components option as well.
    Does that make sense?

  • Need some low level help/info on Grid Control / Data Guard

    I need to get some info concerning the set up and administration of Grid Control. In particular, I need to know why Grid Control needs to have the Oracle OS-Level username and password stored in Grid Control in order for GC to set up and manage a Data Guard database.
    Is it because when the database is being created, GC issues commands like RMAN and SCP to put files onto the standby host?
    Also, for accountability purposes, can I not use a named user account (with the same privs as the oracle user) saved as the preferred credential and still perform the necessary functions to use DG and GC together effectively.
    Probably a lot of info and variables, and I've not explained much, but happy to explain further if needed.
    Thanks!
    Edited by: joe.bednarz on Oct 14, 2009 9:38 AM

    Thanks for the input... we need to use another account other the "oracle" account so there is some accountability for who does what. If I create an account that has similar privileges as the oracle user, I can still run all things Oracle, while still having a log of my log in time and actions.
    More of security issue...
    Thanks again. Appreciate it!

    Use FM -LVC_FIELDCATALOG_MERGE to derive the field catalog for table VBAK. It will give you the field catalog. You can modify the column VBELN  by changing HOTSPOT = 'X".
    and in your code - at the method SET_TABLE_FOR....DISPLAY , you comment out the structure name and pass the modified field catalog.
    Hope it helps.

  • Do not include some lines in Subtotals and totals in ALV

    Hello All,
    I am printing a report with all sale order details and Quantities( delveered ,conformed etc..) iam doing subtotals based on the material and Plant.
    In this if the document date is less than the SY-DATUM, we should not include the quantity into the subtotals and totals, Only the orders wiht doc date GQ to Sy-datum then display them..
    As of now I am using ALV grid display and doing the sums by 
    l_wa_fcat-do_sum = c_x. (field catalog) for the whole colom) but i want to avoid sum row from tehe calculation based on the condition.
    <b>Do we have any way to achive this, like if we want to have separate color for a purticular Cell then we add an extra field in outout table and we link this field with layout-coltab_fieldname in the same way or any other way if we have</b>.
    I will be  thankfull to if you can provide me your valuable suggesstions on this. it is very urgent. I am trying in all the ways from my side.

  • OO concept in ABAP

    Hi..
    Anyone could explain me the OO concept in Abap.?
    Any materials available to learn this concept. If so, plz provide  me.
    Thanks in advance.

    Hi this may be of some help.
    OOPs ABAP uses Classes and Interfaces which uses Methods and events.
    If you have Java skills it is advantage for you.
    There are Local classes as well as Global Classes.
    Local classes we can work in SE38 straight away.
    But mostly it is better to use the Global classes.
    Global Classes or Interfaces are to be created in SE24.
    SAP already given some predefined classes and Interfaces.
    This OOPS concepts very useful for writing BADI's also.
    So first create a class in SE 24.
    Define attributes, Methods for that class.
    Define parameters for that Method.
    You can define event handlers also to handle the messages.
    After creation in each method write the code.
    Methods are similar to ABAP PERFORM -FORM statements.
    After the creation of CLass and methods come to SE38 and create the program.
    In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
    Example:
    REPORT sapmz_hf_alv_grid .
    Type pool for icons - used in the toolbar
    TYPE-POOLS: icon.
    TABLES: zsflight.
    To allow the declaration of o_event_receiver before the
    lcl_event_receiver class is defined, decale it as deferred in the
    start of the program
    CLASS lcl_event_receiver DEFINITION DEFERRED.
    G L O B A L I N T E R N A L T A B L E S
    *DATA: gi_sflight TYPE STANDARD TABLE OF sflight.
    To include a traffic light and/or color a line the structure of the
    table must include fields for the traffic light and/or the color
    TYPES: BEGIN OF st_sflight.
    INCLUDE STRUCTURE zsflight.
    Field for traffic light
    TYPES: traffic_light TYPE c.

  • Could you please send me the material Opps concepts Classes and Methods

    Hi Experts,
    I am working on Opps concepts.I am new to this concept.
    Could you please send me the detailed presentation on Abap oops.
    Thanks inadvance,
    Regards,
    Rekha.

    Hi this will help u.
    OOPs ABAP uses Classes and Interfaces which uses Methods and events.
    If you have Java skills it is advantage for you.
    There are Local classes as well as Global Classes.
    Local classes we can work in SE38 straight away.
    But mostly it is better to use the Global classes.
    Global Classes or Interfaces are to be created in SE24.
    SAP already given some predefined classes and Interfaces.
    This OOPS concepts very useful for writing BADI's also.
    So first create a class in SE 24.
    Define attributes, Methods for that class.
    Define parameters for that Method.
    You can define event handlers also to handle the messages.
    After creation in each method write the code.

  • OOPS abap

    hi experts,
    I want to learn OOPS ABAP. Starting from classes , objects , their syntax , i have seen lot of documents but i am not ablre to understand the syntax, plz guide me with useful informations
    or you can send me material related to this on [email protected]

    Hi this will be helpful.
    OOPs ABAP uses Classes and Interfaces which uses Methods and events.
    If you have Java skills it is advantage for you.
    There are Local classes as well as Global Classes.
    Local classes we can work in SE38 straight away.
    But mostly it is better to use the Global classes.
    Global Classes or Interfaces are to be created in SE24.
    SAP already given some predefined classes and Interfaces.
    This OOPS concepts very useful for writing BADI's also.
    So first create a class in SE 24.
    Define attributes, Methods for that class.
    Define parameters for that Method.
    You can define event handlers also to handle the messages.
    After creation in each method write the code.
    Methods are similar to ABAP PERFORM -FORM statements.
    After the creation of CLass and methods come to SE38 and create the program.
    In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
    Example:
    REPORT sapmz_hf_alv_grid .
    Type pool for icons - used in the toolbar
    TYPE-POOLS: icon.
    TABLES: zsflight.
    To allow the declaration of o_event_receiver before the
    lcl_event_receiver class is defined, decale it as deferred in the
    start of the program

  • Notes on using Object  oriented concept in ABAP

    Hi ,
    I want somes notes on how to use Object  oriented concept in ABAP.
    Thanks in advance.
    Chetan

    Hi, this may help you
    OOPs ABAP uses Classes and Interfaces which uses Methods and events.
    If you have Java skills it is advantage for you.
    There are Local classes as well as Global Classes.
    Local classes we can work in SE38 straight away.
    But mostly it is better to use the Global classes.
    Global Classes or Interfaces are to be created in SE24.
    SAP already given some predefined classes and Interfaces.
    This OOPS concepts very useful for writing BADI's also.
    So first create a class in SE 24.
    Define attributes, Methods for that class.
    Define parameters for that Method.
    You can define event handlers also to handle the messages.
    After creation in each method write the code.
    Methods are similar to ABAP PERFORM -FORM statements.
    After the creation of CLass and methods come to SE38 and create the program.
    In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
    Example:
    REPORT sapmz_hf_alv_grid .
    Type pool for icons - used in the toolbar
    TYPE-POOLS: icon.
    TABLES: zsflight.
    To allow the declaration of o_event_receiver before the
    lcl_event_receiver class is defined, decale it as deferred in the
    start of the program
    CLASS lcl_event_receiver DEFINITION DEFERRED.

    INCLUDE STRUCTURE zsflight.
    Field for traffic light
    TYPES: traffic_light TYPE c.
    Field for line color
    types: line_color(4) type c.

    Dear all,
    When should one go for object oriented programming...Also i am new in OOPs..how should i start about it?
    Also can anyone tell me which books to study from ABAP certification...i know there are TAW10 and TAW12...but how to find out which are the latest releases of this books

  • Module pool using ABAP Objects

    Hi All ,
         I have a requirement for creating a transaction/module pool prog using OO ABAP  .
        Can you please send some sample documents to guide completely about the creation and execution of the transaction .
    Rewards are assured !!
    Regards,
    Ranjita

    Hi
    see this code for ALV report in which we used the Modules which is similar to Module pool
    OOPs ABAP uses Classes and Interfaces which uses Methods and events.
    If you have Java skills it is advantage for you.
    There are Local classes as well as Global Classes.
    Local classes we can work in SE38 straight away.
    But mostly it is better to use the Global classes.
    Global Classes or Interfaces are to be created in SE24.
    SAP already given some predefined classes and Interfaces.
    This OOPS concepts very useful for writing BADI's also.
    So first create a class in SE 24.
    Define attributes, Methods for that class.
    Define parameters for that Method.
    You can define event handlers also to handle the messages.
    After creation in each method write the code.
    Methods are similar to ABAP PERFORM -FORM statements.
    After the creation of CLass and methods come to SE38 and create the program.
    In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
    Example:
    REPORT sapmz_hf_alv_grid .
    Type pool for icons - used in the toolbar
    TYPE-POOLS: icon.
    TABLES: zsflight.
    To allow the declaration of o_event_receiver before the
    lcl_event_receiver class is defined, decale it as deferred in the
    start of the program
