Coordinate System SRID GeoRaster data

Hi All,
I'm learning GeoRaster and I have some problems setting the coordinate system.
I've successfully loaded ArcGis Raster data (binary grid) using FME. I can run queries using sdo_geor.getCellValue using the numRow and numColumn parameters. my question is:
How can I run the same query using the model coordinates (*British National Grid*) instead of the pixel coordinates ?
Thanks !

please follow these steps:
1. make sure the loaded georaster object is properly georeferenced and has the model srid set. call sdo_geor.validategeoraster and sdo_geor.getmodelsrid.
2. find the Oracle srid for British National Grid.
3. directly call SDO_GEOR.getCellValue(
georaster IN SDO_GEORASTER,
pyramidLevel IN NUMBER,
ptGeom IN SDO_GEOMETRY, - where your point in your srid - any srid is fine
layers IN VARCHAR2
) RETURN SDO_NUMBER_ARRAY;
4. you can convert cell coordinates (numRow, numColumn) to/from ground coordinates (X,Y) whenever needed. call sdo_geor.getModelCoordinate and sdo_geor.getCellCoordinate

Select data with SDO_RELATE in lat long coordinate system(8307) in 10gR2

Hi all,
I have problem with selecting data from table.
Data are in lat lon coordinate system 8307.
These requests don't return any data:
SELECT ISSUE_ID FROM MAP_ISSUES WHERE SDO_FILTER(GEOMETRY, sdo_geometry (2003, 8307, null, sdo_elem_info_array (1,1003,1),sdo_ordinate_array(-180,-90, 180,-90, 180,90, -180,90, -180,-90)) ) = 'TRUE';
SELECT ISSUE_ID FROM MAP_ISSUES WHERE SDO_RELATE(GEOMETRY, sdo_geometry (2003, 8307, null, sdo_elem_info_array (1,1003,1),sdo_ordinate_array(-180,-90, 180,-90, 180,90, -180,90, -180,-90)), 'MASK=ANYINTERACT' ) = 'TRUE'
Optimized polygon does return all data correctly:
SELECT ISSUE_ID FROM MAP_ISSUES WHERE SDO_FILTER(GEOMETRY, sdo_geometry (2003, 8307, null, sdo_elem_info_array (1,1003,3),sdo_ordinate_array (-180,-90,180,90)) ) = 'TRUE'
Smaller polygon select data correctly too.
SELECT ISSUE_ID FROM MAP_ISSUES WHERE SDO_FILTER(GEOMETRY, sdo_geometry (2003, 8307, null, sdo_elem_info_array (1,1003,1),sdo_ordinate_array (52,-7, 54,-7 , 54,-5 , 52,-5, 52,-7)) ) = 'TRUE'
I have tried changed polygon to be clockwise, counter clockwise, make the area a bit smaller( 160 instead of 180, 89 instead of 90) nothing has helped.
My explanation than was, that Earth is sphere and each defined polygon defines TWO polygons in the sphere and there is convention that the smaller is chosen to select data. It would make sense along the previous results, but than I found one post which says that this is bug http://www.frontoracle.com/oracle-database/703/180703-size-of-are-of-interest-smaller-equals.html
I have found in other thread that max only 1/2 of Earth could be selected Different results using SDO_RELATE with polygon and rectangle type but it seems not true, because optimized bounding box works fine!
What is right? Is there anything in official documentation?
Is it bug.
Max 1/2 of Earth could be selected in one request.
Each polygon defines two areas in the Earth and the smaller one is used to do spatial SDO_RELATE operation?
Thanks!
Regards,
Zdenek

Zdenek,
A bug, or limititation, whichever you choose. IMHO if you ask for something, and don't get what you expect, it is a bug that could be fixed.
But for 10g anywho, the following applies, which is why I choose 120 degree breaks for my code as it is less than 180...
The following size limits apply with geodetic data:
■ No polygon element can have an area larger than one-half the surface of the Earth.
■ In a line, the distance between two adjacent coordinates cannot be greater than or
equal to one-half the perimeter (a great circle) of the Earth.
If you need to work with larger elements, first break these elements into multiple
smaller elements and work with them. For example, you cannot create a geometry
representing the entire ocean surface of the Earth; however, you can create multiple
geometries, each representing part of the overall ocean surface. To work with a line
string that is greater than or equal to one-half the perimeter of the Earth, you can add
one or more intermediate points on the line so that all adjacent coordinates are less
than one-half the perimeter of the Earth.

How to add coordinate system SVY21(SRID: 3414) to Oracle Spatial 11g/12c

Can any one please help me for "How to add coordinate system SVY21(SRID: 3414, for Singapore) to Oracle Spatial 11g/12c'?

Why don't you start with the documentation: Coordinate Systems (Spatial Reference Systems)
Especially paragraph 6.9 (6.9 Creating a User-Defined Coordinate Reference System ) should be helpful for you.

ORA-13487: SRID not found for source coordinate system metadata

Hi,
When executing the following
DECLARE
g SDO_GEORASTER;
BEGIN
SELECT raster INTO g FROM CADRE_AWIFS_GEORASTERS
WHERE row_id = 3 FOR UPDATE;
SDO_GEOR.IMPORTFROM
g, 'SRID=8307',
'GEOTIFF','FILE',
'/Oracle2/usr/local/src/cadre/raster_import_orcl/BAND2.TIF'
UPDATE CADRE_AWIFS_GEORASTERS SET raster = g
WHERE row_id = 3;
COMMIT;
END;
I get the error ORA-13487
How can I find the SRID that's making it blow up?

your file is geotiff, so you should remove "SRID=8307' from the storage parameter. instead, always apply blocksize.
to find out what kind of coordinate system is inside your geotiff file, you can use many tools. if you don't have the tools, recommend listgeo.exe or gdalinfo. both are open source and can be dowloaded and installed in minutes.
you may call sdo_cs.find_srid to search the equivalent CS in oracle spatial. or simply check the WKTEXT in the cs_srs table to find out.

Problem with transforming coordinate systems

Hiho,
i've got a problem with transforming coordinate systems.
When I'm trying to transform a sdo_geometry object to another coordinate sytem and then back to the old system, the coordinates are not the same.
Here's an example:
StartSystem SRID is 8220 (Longitude / Latitude (DHDN))
TargetSystem SRID is 8307 (Longitude / Latitude (WGS84))
Original object:
Polygon: {ExteriorRing: LineString: { (0.0, -90.0) (1.5, 0.0) (0.0, 90.0) (4.5, 0.0) (0.0, -90.0)} }
Transformed object:
Polygon: {ExteriorRing: LineString: { (0.0, -5156.620156177403) (85.94366926962347, 0.0) (0.0, 5156.620156177403) (257.8310078088704, 0.0) (0.0, -5156.620156177403)} }
Transformed back to old system:
Polygon: {ExteriorRing: LineString: { (0.0, -5156.620156177403) (4924.209525017614, 0.0) (0.0, 5156.620156177403) (14772.628575052844, 0.0) (0.0, -5156.620156177403)} }
Any ideas what to do?
Thanks for the help in advance.
Dirk

Hi Dirk
Since the transform you are trying to do is just a datum conversion of lat./long. coordinates, even the first transform yields obvious rubbish. What you have provided here does not illustrate how you submitted your polygon to CS_TRANSFORM.
Provide the syntax of your construction of the corresponding SDO_GEOMETRY object and your SQL select statement that gave these results.

This is probably almost a year too late but I had the same problem and was able to resolve it by registering the recently imported geoRaster data
SQL>select * from the (select sdo_geor_admin.listGeoRasterObjects from dual);
This will likely show that you have 'unregistered' data and the following will register it after which your validation calls should all return true instead of 13442
SQL>execute sdo_geor_admin.registerGeoRasterObjects;
SORRY -- I just saw that you'd already done the registerGeoRasterObjects bit msm

Coordinate system translation from screen coordinates to stage coordinates

I realize this is not truly a LabVIEW question, but I'm hoping for suggestions.
I have a digitized image of a sample on a 3 axis stage. The user selects "paths" for a drill to take along the surface of the sample. On the image, 3 reference points are identified. The stage posititions (x, y, and z) corresponding to these points are then identified.
I need to now convert the coordinates of the paths to the stage coordinate system. Are there any LabVIEW vi's that are suited to this need? I have IMAQ vi's but not very experience with these yet. Suggestions much appreciated
Tim

Hello Shan:
Were almost have the same problem but mine is for a AOI handler with a robot arm which I need to pick (x,y) pairs along the work envelope. Anyway, for the most math part it will involve are coordinate transformation from a "mouse coordinates" to "real world coordinates" and your image processing textbook (I use McGrawHill Computer Graphics by Hill) will outline both the code and the math but LabVIEW will not have a facility to do with an actual VI instead you have to use the array manipulations and treat them coordinates as matrix elements. There is a Math VI and G-Math VI or a MatLAB call you can use for coordinate matrix manipulations as long as you have the math quite figured out in paper already.

Connection between 2 points in a geodetic coordinate system

In a geodetic coordinate system the connection between two points is a geodetic line or "great circle" (the shortest connection between two points on the surface of the earth).
Since Oracle 9i distances and queries like "Is a point outside or inside the polygon" are computed correctly for a geodetic coordinate system.
Even though a circle or arc is not allowed in a geodetic coordinate system (like WGS84 - SRID 8307)
arcs and circles are used in geographic applications like aeronautical maps.
Frequently a special area is defined like this "10 nautical miles around airport XXXX"
and this area is shown as a circle in aeronautical maps (in the projection).
The function SDO_UTIL.CIRCLE_POLYGON (in Oracle 10g) is very useful to construct such kind of areas and for queries like
"Does the area belonging to airport XXXX overlap with the area belonging to airport YYYY?".
For Oracle 8i we had to write special PL/SQL code.
Another type of connection between two points that is frequently used is a line of equal latitude (parallel).
Many boundaries are defined like "from meridian (longitude) 30Â°E to meridian 31Â°E along parallel 47.5Â°N".
If this line is a border of a polygon and if we use a direct connection (geodetic line) and we ask if a point is
inside or outside the polygon, we will not get the correct answer if the point is close north to this line.
We have to approximate the line and add points e.g. every 0.1Â° longitude (30.1,30.2,30.3...), then the answer will be correct.
My question:
Are there plans to support circles of equal latitude or generally rhumb lines as a type of connection between two points?
Karl Mann

There are no plans to support rhumb lines, also know as loxodromes, and including the special case of parallels of latitude, at this time. Note that it is easy to simulate such rhumb lines with a sufficiently dense set of sampled points. Such a densification is implemented implicitly for parallels in the VIEWPORT_TRANSFORM function so that the concept of the "geodetic minimum bounding rectangle" can be supported, primarily for visualization applications.

Selecting a coordinate system

Oracle 9i provides a big set of projected and geodetic coordinate systems. We've got a database full of points (latitudes and longitudes), mostly in the USA, and we're adding Oracle geometries to our database so we can do spatial indexing and quick nearest neighbor calculations. We want to use a projected coordinate system, for speed, but the question is: What's the best coordinate system for our purpose?
Most of our locations are < 10 miles apart, so we probably don't need location-specific projections like "Massachusetts Mainland Zone" .. unless there's a way to let Oracle decide which projection to used based on the latitude/longitude (that would be nice, eh?)
Anyway, I'm just a bit overwhelmed by the number of options here, as usual with Oracle.
Thanks!
Greg

Hi,
I'm not an expert on coordinate systems, but at first look I would leave the data in long/lat and
use a geodetic R-tree index. R-trees are excellent for nearest neighbor calculations, and
although it does take Spatial a bit longer to do the distance calculations for geodetic data
vs. projected data, the simplicity and accuracy of the solution would be compelling reasons
to leave the data as is. Also, unless the data is extremely dense the extra time associated with
geodetic distance calculations will get lost in the noise. The best case would be if the query
window is also a point - the timing will degrade if the query window is a complex polygon.
Any single projection for an area as large as the US will have distortions that may effect the
validity/accuracy of the data, but it will be fast...
Hope this helps,
Dan

Remote system monitoring entry- data not relayed to Central system

Hello Folks,
I am trying to establish a central monitoring system for our client. I am trying to test it in the DEV environment first.
The central system is a Solution manager system (Dual stack- ABAPJAVA). I am trying to bring in monitoring data from the ECC development environment (ABAPJAVA).
First of, i created to RFC connections in Solution manager system, one for data collection and the other for analysis. I have maintained the host address of the ECC system as target.
Then i have created a remote system entry in Transaction RZ21--> technical infrastructure entered the 2 RFC names and have executed the function.
At this point i am only trying to bring in ABAP stack monitoring data form the ECC system so i have not generated the CSNCONF file.
Now when i look in Solution manager RZ20-->CCMS monitoring templates, i can't see any data for the the ECC system.
I guess i am doing something wrong. Am i looking in the wrong monitor set?
As additional information: Solution manager (SMD) and ECC (ECD) use different transport domains / transport groups. I dont know if this makes a difference.
Can some one please help.
Regards,
Prashant

Hi Prashant,
if I understand correctly your system shows only MTEs from R/3 Stack, not from the OS side, pls check your SAPOSCOL. Are the data in OS06 in your remote system correct and do you see the current data, refredhed all 10 seconds?
To check your environment, pls do the following:
in th efirst step check in RZ21 > in the Topology part the System Overview for your system connection to your back end system. Are the Read Destination Data RFC and the Destination Analysis RFC correct and works the authority chek fine?
In the second step pls check in RZ21 > in the Agents for Remotey SAP Systems part; are there registered your remote ccms agents correctly and works the connection test.
Stop the agents and in your RZ20 monitor pls enter STAT in your command field. Are there displayed for your MTE nodes the read RFC destinations?
Start the agents and and in your RZ20 monitor pls enter STAT in your command field. Are there displayed for your MTE nodes the CCMS Agent RFC destinations?
To rebuild the Monitor in the CEN system you could try to reset the node of your remote system in the warm up status > go in the remote system to RZ1 > go to local segments > change to edit > select your segments > reset segment in "WARMUP" status.
In the CEN system you coul try to go to the edit mode for the Agents for Remot SAP Systems > select your remote system and push the button Reinitialize Agents
In the back end system you can try to delete all MTEs in RZ21 > menu Technical Infrastructure > Reorgenize Segment Table > select the options with "ALL" in the CEN and the remote system to reorgenize all data.
Could you pls post for the missing MTEs a screenshot on the one side from the CEN system and on the other side from the remote system...
and last but not least you could try the following for missing OS MTEs
delete ALALERTS, ALMTTREE and ALPERFHI in /usr/sap/ccms/<SID>_<SNR> and check in the agents folder all trace and log files for errors.

How can I get the coordinate in the layer coordinate system while doing the iterate?

I found that the position(x,y) the iterate function tell me is not right sometimes.
Actually,it happens when the top of the layer is negative. The "y"is in the comp coordinate system(maybe?) but not the layer.In another word, the position with y=0 is not the top.
More specifically, I have got the color map of a layer. I am able to get the color of any pixel in the layer. But I can't set the color one for one when I use "iterate",because there is an offset.
Am I supposed to get the offset? Is there any way to access the whole layer directly if I use iterate function?

so indeed it's the offset at play.
AE will diminish the buffer at 20% increments, and not for each pixel that
goes out of sight. it's not really in relation to the upper left corner,
it's all about what part of your layer buffer is out of sight.
there's also an "iterate offset function". check it out. perhaps it will
save you some trouble.
