3d geometries in mapviewer

Does anybody know when 3D will be available in Mapviewer?
Thanks,
Viorel

Hi,
rendering of FOI elements in Oracle Maps does not show the label value. If you mouse over the FOI, then you see the label information. If you want to have the label rendered, you can add it as a theme on the basemap, and then create the FOI theme to display information when you mouse over or double click the feature.

Spatial Queries

Hi,
I'm looking for a solution on fetching Spatial Data from an Oracle Spatial database (9.0i) into php. Oracle returns an error upon fetching. Executing the SQL-statement doesn't give any trouble, but fetching te data into PHP does. While using OCIFetchInto() Oracle returns an inconsistant datatype error. The goal is to fetch the coordinates stored in the database.
I Hope somebody has a solution to this problem?

Hi,
Here is an example of a spatial query copied from http://otn.oracle.com/oramag/webcolumns/2003/techarticles/hull_php.html , but with a spatial component:
SELECT /*+ ordered */ w.well_id, w.is_contaminated
FROM land_use_polygons l, wells_table w
WHERE l.land_type = 'agricultural'
AND sdo_within_distance (w.geom, l.geom, 'distance=5 unit=kilometer') = 'TRUE';
or here is a query selecting point data:
SELECT /*+ ordered */ w.well_id, w.is_contaminated,
w.geom.sdo_point.x, w.geom.sdo_point.y
FROM land_use_polygons l, wells_table w
WHERE l.land_type = 'agricultural'
AND sdo_within_distance (w.geom, l.geom, 'distance=5 unit=kilometer') = 'TRUE';
If you need to display geometries, Oracle9iAS MapViewer has an XML API that may be useful for rendering the geometry data.
Hope this helps,
Dan (have spatial knowledge, but not PHP)

Checkboxes: How do you use them to select geometries for display, MapViewer

Dear all
I am working in Oracle 10.2 and using PL/SQL. I am trying to create a procedure that generates a list of spatial layers, based on those currently contained in the database, which uses checkboxes, so that users can select which layers to display.
Once the user has made his choices and the results are submitted, the chosen layers are displayed through MapViewer. Currently the procedure, which is still being developed, is as follows:
PROCEDURE MAPLIST AS
CURSOR curmaplist IS
SELECT spatial_map_name
         spatial_map_id
         geom
   FROM spatial_map_table;
varmaplist curmaplist%ROWTYPE;
   varchecked VARCHAR2(32767);
BEGIN
FOR varmaplist in curmaplist LOOP
htp.print('<FORM>
              <UL>
               <LI>
                <LABEL FOR="SM_ID||
                            curmaplist.spatial_map_id||">
                 <INPUT type="checkbox"
                        id="SM_ID||
                            curmaplist.spatial_map_id||"
                        name="SM_ID||
                              curmaplist.spatial_map_id||"
                        value="MAP TITLE: ||
                               curmaplist.spatial_map_name" />
                </LABEL>
               </LI>
              </UL>
             </FORM>'
EXIT WHEN curmaplist%NOTFOUND;
   END LOOP;
END;I am not sure how to incorporate the checked element and then make use of it. Regarding subsequent use, I wondered if an IF statement could be used.
IF VARCHECKED = 'CHECKED' THEN...after this MapViewer XML is added, with the select statement making use of the cursor. For example:
select curmaplist.geom
from geg50160.spatial_map_tableFor the checked part itself, I have found the following Oracle code in Chapter 11 of Oracle Database Application Developer’s Guide - Fundamentals 10.2.
CREATE OR REPLACE PROCEDURE handle_checkboxes ( checkboxes owa_util.ident_arr )
AS
BEGIN
FOR i IN 1..checkboxes.count
LOOP
htp.print('<p>Checkbox value: ' || checkboxes(i));
END LOOP;
END;
/However I am not certain how I would incorporate that into my code. I take it i refers to the checkbox value. I've read that .ident_arr is an array which can hold multiple values but if so I am also not sure why checkboxes are counted.
Kind regards
Tim

Hi GKaiseril,
Thanks for your reply. That's what I'm attempting to do, but I'm largely trying to "borrow" on-line JavaScript (see below) & modify for my PDF Form, w/ rudimentary knowledge gained while surfing the web. The Form has 30 checkboxes that I want to limit users to a max. of 4.
So any add'l scripting tips would be most appreciated.
Thanks!
var NewCount = 0
getField("Check_Box1").value === "Yes"
{NewCount = NewCount + 1}
getField("Check_Box2").value === "Yes"
{NewCount = NewCount + 1}
getField("Check_Box3").value === "Yes"
{NewCount = NewCount + 1}
getField("Check_Box4").value === "Yes"
{NewCount = NewCount + 1}
getField("Check_Box5").value === "Yes"
{NewCount = NewCount + 1}
if (NewCount == 4)
app.alert(“Pick Just Four Please”); return false;

Loading (point) features takes MapViewer 20 times sql exec time?

I have a map which contains only one theme which shows 14500 point geometries stored in a table (accessed via a view). Rendering the map takes a long time, more than 22 secs. Looking at the log from MapViewer it seems like the sql execution time is not the problem, also in a sql editor the query is fast. Labeling and rendering is fast too. CPU is not very busy while rendering the map, memory usage is under 70 MB. The problem seems to be loading the features after executing the sql query.
This is the logging:

22 seconds is too long for our application. Does anyone know what could be wrong and what I could do to improve this?
Thanks in advance,

22 secs seems too long.

ORA 00600 Error when using Mapviewer addJDBCTheme

Hello
I am receiveing the 600 error via my OC4J window when using mapviewers addJDBCTheme with the passTthrough boolean set to false (the query is rewitten by mapviewer to limit it to the results to the map view). If I perfrom the same query with passThrough set to true, no problems. I have a feeling this may relate to the index on my table. OC4J output for error below.
Any ideas appriciated.

Chris,
Can you run this rewritten query
SELECT * FROM ( select spat_data, mbl_bka_id, mbl_title from WPE_SPATIAL_BLOCKS_VIEW_10G c ) WHERE MDSYS.SDO_FILTER(spat_data, MDSYS.SDO_GEOMETRY(2003, 81989, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3), MDSYS.SDO_ORDINATE_ARRAY(278472.6,186744.0,279272.6,187544.0)), 'querytype=WINDOW') = 'TRUE'
in sql*plus without any errors?
The asumptions is there is a spatial index on spat_data and all the geometries are valid.
Also there will be a trace file on the db server. That'll give more details on what the likely cause is.

How to use MapViewer API?

Hi,
I have a problem that is acturally regarded to java programming. I want to use MapViewer JavaBean-Based API. I did the preparing work described in Mapviewer doc §4.2.
I saved the demo jsp page "mapclient.jsp" in my own application folder (under oc4j\j2ee\home\default-web-app). The other jsp pages written by myself can be displayed. But this mapclient.jsp can not be retrieved. "HTTP 500 internal server error The page cannot be displayed." It seems that I don't have J2EE container that contains the MapViewer service.
I also changed the codes of mapclient.jsp. I use
import oracle.spatial.mapclient.MapViewer;
MapViewer mv = new MapViewer("http://localhost ...");
It does not work, either. "The page cannot be displayed."
I don't know how to invoke the MapViewer service. I use oc4j standalone. I don't know how to get the error message, either.
I hope somebody can give me some suggestions. Thanks in advance.

Hi,
about the addDataSource using the Java API, for now you have to disable the security
in order to add the data source using the MapViewer client API.
You can do that editing the MapViewer config file:
<mv_security enforce_sec_role="false" />
Assuming that you have added your data source, and you have rendered some map,
you can get the attribute information using the "identify" methods of the
MapViewer client API.
1) To identify one individual geometry:
String [][] result = mapviewer.identify(dataSource,table_name,columns,
geometry_column,srid, x, y);
where: "columns" contains the table attribute names that
you want to retrieve
x,y represents the device coordinate.
2) To identify geometries inside a rectangle:
String [][]result = mapviewer.identify(dataSource,table_name,columns,
geometry_column,srid, xlowleft,ylowleft,
xupright,yupright,false);
where the rectangle coordinates are defined by xlowleft,ylowleft,
xuprigth, and yuprigth values in device unit.
3) The resulted String array contains on the first row the attribute
names, and on the remaining rows the attribute values for each geometry.
int nlin = result.length; // return the number of lines
int col = result[0].length; // number of columns
To get the attribute names:
// attribute names
Object []tableattrs = new Object[ncol];
for(int j=0;j<ncol;j++)
tableattrs[j] = result[0][j];
To get the attribute values:
Object [][]tablevalues = new Object[nlin-1][];
for(int lin=1;lin<nlin;lin++)
tablevalues[lin-1] = new Object[ncol];
for(int col=0;col<ncol;col++)
tablevalues[lin-1][col] = result[lin][col];
Regards.

MapViewer 1.0 rc1 and Oracle Database 10g 10.1.0.2.0 Performace

I have just loaded the MV Demo and was a little disappointed at the performance. Below, I posted a sample of database fetch/rendering times. I was wondering if this was typical since this was my first experience with Map Viewer. And if not, where can I get some information to improve performance?

Thank for the quick reply. I was just doing a basic test to determine if Map Viewer would satisfy our target architecture and rich web client functional requirements. Everything checks out except for my lack of understanding on how to determine the best performance settings. I expect the development environment to be slower than production. Our actual production environment is many load balanced map and database servers.
Sorry about the lack of details.
Terry

Understanding MapViewer log - total time loading X features

Hi All,
I'm interested in finding out more about how to understand the following lines from the log file.
What I'm unsure about is what "total time loading features" means. For example Theme_14 has a sql exec time of 1797ms, however the total time loading 3 features is 21233ms.
I'm assuming the total time includes the sql exec time. However there is about 20 seconds extra. Understanding this time should allow me to make changes to reduce it.
What is MapViewer doing in that time? / What are the components that make up the "total time loading features"?

Your time is appreciated. Any other comments are also welcome.

Hi,
the "total time loading features" includes the whole process to prepare the theme data. It includes the SQL execution time plus the data fetching plus some other minor tasks which do not affect much the final total time. So basically look for the SQL exec time and the fetching/loading of data. In your case, the fetching/loading of THEME_14 geometries is taking too long. Also the SQL exec time for just 3 features seems high. For the fetching, check if the geometries are too detailed (too may points), and for the SQL check if you can improve it (the log, in finest mode, also shows the query executed).

Best method to move data from ArcSDE to Oracle Spatial/Mapviewer environment?

If ArcGIS Geodatabase is the standard data store for GIS data, but business IT wants to make use of an Oracle Spatial/Mapviewer environment, what is the best practices recommended approach for interfacing between the two data stores. (perhaps this is an Oracle Spatial question, but tools exist here as well.)

Yes, This question is more suited for the Oracle Spatial Forum.
And about the question, you must use Esri's owns products like ArcCatalog or Arcmap to connect to oracle and change the format of your geometries. Arcgis is capable of storing geometrical data in oracle in SDO_Geometry format.
If you have question about the procedure of this action, don't hesitate to ask.

MapViewer topology and get_geometrymember function

Hallo everybody,
can Mapviewer show geometries that come from the member function get_geometry of a topology object. Or may I calculate for all my topology the geometry in this way and then store it?
Thanks Jade

yes mapviewer can show the results of get_geometry call.

Feature request for Mapviewer for styling rules in predefined themes

Hi,
i have a bunch of predefined themes in MapViewer with quite a lot of rules for each of them. They are all of the same structure
<ruleA>...
<ruleB>...
<ruleOtherwise> If not ruleA and not ruleB ....
Since every rule is being processed, you have to define a quite big "where" cirteria in ruleOtherwise in order to process only when no other rule fit.
I think an explicit "default" or "otherwise" rule would be a great enhancement for these cases. It should be called when no other rule fits,
Regards,
Holger

I launch this resquest with 2 themes. First one for geometries 2001 and the secound one for the others. But only get the results for the first theme. Think there is something wrong, is possible that the request only allow one theme? so it wouldn't make any sense the <themes> tag.
<map_request>
<themes>
     <theme name='JDBC_THEME'>
          <jdbc_query asis='true' spatial_column='value' jdbc_srid='8307' label_column='label' render_style='M.MARKER' datasource='DSTest'>
          SELECT g.value,g.annotation as label FROM geometries g WHERE g.value.sdo_gtype = 2001</jdbc_query>
     </theme>
     <theme name='JDBC_THEME'>
          <jdbc_query asis='true' spatial_column='value' jdbc_srid='8307' label_column='label' render_style='colorScheme' datasource='DSTest'>
          SELECT g.value,g.annotation as label FROM geometries g WHERE g.value.sdo_gtype != 2001</jdbc_query>
     </theme>
</themes>
</map_request>
Thanks again.

Complex styling in MapViewer

Hi,
I am having a deeper look into Mapviewers styling capabilities, and have a couple of questions:
- Is it possible to customize line styles more, for example make it paint geometrical shapes in given intervals (or if not, is there any plans to do so) ? In my case, it means i.e direction-arrows, crosses, circles etc.
Here is an example that demonstrates it, with both direction arrows and crosses on the same line:
http://img408.imageshack.us/img408/9504/linepumpdirectionandoutmt6.png
- Is there any current plans to implement support for hatching polygons ?
Regards,
Oyvind Idland

I've been able to do hatching with a 5x5 pixel transparent gif. The diagonal pixels from upper left to lower right corners (5 pixels) are the only ones with color. I specify this image in the style and when rendered, mapviewer tiles it and hatches the polygon very nicely. I expect this will work for any symmetrical image.
This is what the image looks like, 0 is transparent, x is color:
x0000
0x000
00x00
000x0
0000x
I'm not sure if it meets your entire needs, but, mapbuilder allows you to define line styles with different dash patterns and cross hatches.

MVMapView.transformGeom and big geometries result in error 05511

Hello,
i have a problem with using MVMapView.transformGeom with geometries with many ordinates. When i try to transform such a geometry object i get a Mapviewer error 05511.
Using Firefox with firebug i could examine the response from the server. It tells me that the Request-URI is too large (414)
I can also see that the parameters are transfered to the server using GET, so it is no wonder that i get that error.
Wouldn't it be better to use POST instead of GET to send the geometry to the server?
I had a deeper look at the oraclemaps.js and found out that for example getLenght or getArea seem to use POST, so i tried to modify transformGeom in the same way, but that didn't work. It still builds a long URI instead of posting a parameter array ( If you look at the request in firebug, you will notice that the POST-TAB is empty. Normally the parameters should appear there, like for example in a getfoi request)
Now i wonder if there is another way to transform a big geometry.
Or maybe the transformGeom function can be altered to use POST instead of GET in the next version of mapviewer.
Regards,
DIrk

Yeah, we should have put the request parameters in the request body, not the URL.
Based on your post, I believe you're capable of fixing it by yourself. What you need to do is to take the request parameters out of the URL, change the method from "GET" to "POST" and send the parameters separately in the request.send call. The line that defines the request URL has "request=cstransform&dstsrid=" in it.
This is a temporary solution. We'll fix it in our code. Don't do it if you're not sure about what I am talking about.

Straight lines are displayed as curved in Oracle Mapviewer

Hi,
we're using Oracle Mapviewer to display land area singlepart polygons (3003) from Oracle Spatial table called sdo_kol. The table has an attribute of mdsys.sdo_geometry. I'm pretty sure that data is loaded correctly using shp2sde tool from arcSde tool pallete. The thing is, when displaying the area's using ArcMap 8.3 we get the polygon shape on the screen. But when we look at the same thing through the Map Viewer the polygon lines look like zig-zag lines instead of straight lines.
Anyone has an idea why?
Cheers.

I have tried the fast_unpickle option. I've set the fast_unpickle to false in user_sdo_maps (we're using predefined themes), or even issuing a manual xml api request with fast_unpickle = "false". I still get zigzag lines.
This has to be a bug in 9.0.4 version of map viewer. Our geometries are of type 3003 and 3007 and one polygon has a lot of vertices, so that might be a rounding problem. We'll try the same thing on 10.1.2.0.2 and see what happens.
Many thanks for your help, you have been very kind.
