• Is there a function in Oracle Spatial 11 g moving/translation of geometry?

  Hello everyone,

  I am new to Oracle Spatial. I wanted to know if there is any function to move/translate a geometry in Oracle Spatial 11 g? PostGIS is a function named ST_Translate to achieve the same.

  Kind regards

  Shiva Shankar

  Hello

  There's a SDO_UTIL. Function AFFINETRANSFORMS in Package SDO_UTIL (utility)

  Note, that Simon Greener & Siva Ravada have published an excellent book ("application and Oracle Spatial extension") which contains (in Chapter 7) examples of easy to use this packages:

• Image SPOT in Oracle Spatial loading

  Hello
  
  We have a SPOT images with file .dim brandishing the dimensions. Is it possible to load the file into an Oracle Spatial Georaster table?
  
  Thanks and greetings
  Manoi

  Yes,

  You can use gdal_translate GDAL (www.gdal.org) for this.

  He manages the Dimap SPOT files:

  http://www.GDAL.org/frmt_various.html#dimap

  And manages Oracle Spatial Georaster:

  http://www.GDAL.org/frmt_georaster.html

  See the instructions on how to download and install to:

  http://trac.OSGeo.org/GDAL/wiki/DownloadingGdalBinaries

  If you use Windows, I recommend:

  http://trac.OSGeo.org/OSGeo4W/

  To use GeoRaster you must install "gdal - 1.6" and 'Oracle Spatial libraries' and type:

  C:\ > gdal16

  on the command prompt before using the program version 1.6 gdal_translate:

  C:\ > gdal_translate - of georaster:scott/tiger@orcl input.tif georaster

  Look at the http://www.gdal.org/frmt_georaster.html for more information on how to enter "create options" and specify exactly where you want your GeoRaster to be loaded in your schema.

  Why he behaves differently in oracle? Is there a way I can fix this problem in oracle?
  
  Thank you
  Jigs

  It is NOT a behavior "differently" in Oracle; you did not specify just an order that you expect of your results, so you'll get output in what order the fantasies of the database showing (ie. no guaranteed order). It is an artifact of the way the database chooses to collect the data and databases (or same sets of data within the same database) can and will most likely behave differently.

  Same SQL Server will not be guaranteed to always get your data in an orderly manner if you exclude the order by clause, even if you think that there always display the data in an orderly manner.

  Your solution is to add an order by clause, in the TWO databases, to force the order of the data output.

• Extrude 3D polygons in Oracle spatial

  Dear all,
  
  I have two sets of the footprint of City data imported into the Oracle Spatial already. One is a polygon with x 2D layer and there, and the other is a layer of polygons 3D with z values (x and are identical to the first).
  
  Now, I am trying to extrude 3D for composite 3D polygon based on the value of z. I can extrude the 2D polygons with success with specifying the heights of soil (for example sdo_ordinate_array (0)) and topheights (say, sdo_ordinate_array (20.0)).
  
  However, how extrude the specified polygon 3D taking the z value of each vertex as the heights of floor at a higher height is a problem for me. Since I am very new to use PL/SQL, besides, I'm not sure if it's possible to do.
  
  Here are examples of data extracted the data from the sample:
  Select sample.geom.sdo_ordinates in the sample sample2d_polygon
  NUMBER (715202.739577727,733492.909091357,715206.759608945,733492.412077086,715208.666575034,733506.889047512,715204.72752625,733507.364066093,715202.739577727,733492.909091357)
  
  Select sample.geom.sdo_ordinates in the sample sample3d_polygon
  NUMBER(715202.739577727,733492.909091357,12.4890003204346,715206.759608945,733492.412077086,12.4890003204346,715208.666575034,733506.889047512,12.4540004730225,715204.72752625,733507.364066093,12.4320001602173,715202.739577727,733492.909091357,12.4890003204346)
  
  Can someone help me with this
  Select sdo_util.extrude (sample.geom, sdo_ordinate_array(), sdo_ordinate_array (20.0), 'true', 0.05) sample2d_polygon sample, where the first sdo_ordinate_array is the corresponding z value of the Summit?
  
  Any suggestion is expected and appreciated.

  Hi Jun, -.
  I hope that the following code solves your problem.
  Please make sure also your geometries are valid by using sdo_geom.validate_geometry_with_context or
  sdo_geom.validate_layer_with_context for 3D geometries.
  Please let us know if you have any questions.

• ORACLE spatial 11g and GRS 80

  Hello
  I'm working on a project that will require projected and geographical coordinates for different in product files. I have no problem, define, store, extract or corresponding point coordinates. My columns for these coordinates with the SRID 8307 are defined in user_sdo_geom_metadata table as follows:
  INSERT INTO
  USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
  VALUES
  ('INVENTORYGEOMETRY', 'INVGEO', MDSYS. SDO_DIM_ARRAY (MDSYS. SDO_DIM_ELEMENT ('Longitude',-180, 180,.05), MDSYS. SDO_DIM_ELEMENT('Latitude',-90, 90,.05)), 8307);
  
  the index:
  creating index 'MYDB '. "' INVGEO_IDX ' on 'MYDB '. "INVENTORYGEOMETRY"("INVGEO") indextype is MDSYS. SPATIAL_INDEX;
  
  However, I'm confused as to how I'm going to have a column that has both geographic and coordinated projected. Am I allowed to set longer SDO_DIM_ELEMENT (s) FRO the SDO_DIM_ARRAY with min/max different values. For example, I'd be able to always use an SRID of 8307 times WGS 84 and data GRS80 (ellipsoid), something like the following:
  INSERT INTO
  USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
  VALUES
  ('INVENTORYGEOMETRY', 'INVGEO', MDSYS. SDO_DIM_ARRAY (MDSYS. SDO_DIM_ELEMENT ('Longitude',-180, 180,.05), MDSYS. SDO_DIM_ELEMENT ("' North latitude-90, 90,.05").
  (MDSYS. SDO_DIM_ELEMENT('FIXEDGRID_.5Resolution', 0, 26916,.5)), 8307);
  
  Is that possible or do I have to create a new column in the database?
  
  In addition, I don't know the relationship between the SDO_ELLIPSOIDS and SDO_GEOMETRY tables. You you please explain it to me?
  
  Thank you for any help you can give. I'm confused as to how I'm going to make this work for both geographic and projected coordinates, or if I'll be able to make it work.
  
  Thank you
  Erica

  Erica,

  You have geodetic and projected data in a single column of a table BUT you cannot index in space because the index does not work on the two projections.

  You have, says Bryan, create two columns:

  create table INVENTORYGEOMETRY (
    fid integer,
    INVGEO sdo_geometry, /* For the geodetic data */
    INVPROJ sdo_geometry /* for the projected data */
  );
  

  If you do this, you must create two user_sdo_geom_metadata entries. As you have already done and one for projected data:

  INSERT INTO
   USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
   VALUES ('INVENTORYGEOMETRY','INVPROJ',
   MDSYS.SDO_DIM_ARRAY(MDSYS.SDO_DIM_ELEMENT('X',0,1000, .05),MDSYS.SDO_DIM_ELEMENT('Y',0,1000, .05)),XXXXX);
  

  Where you replace 0,1000 ranges with your actual data range and XXXXX by your actual SRID projected (for example, 28355 as in the example below).

  Now, assuming that this table Gets the INVGEO column populated first (by some external dynamic flow) you could synchronize the column projected via a trigger as follows:

  create trigger inventorygeometry_proj_bi
  before insert
  on inventorygeometry
  FOR EACH ROW
  begin
     if (:new.invgeo is not null) then
       :new.invproj := mdsys.sdo_cs.transform(:new.invgeo,28355);
     end if;
  end;
  /
  

  Finally...

  In addition, I don't know the relationship between the SDO_ELLIPSOIDS and SDO_GEOMETRY tables. You you please explain it to me?

  The SDO_ELLIPSOIDS table is part of the implementation of the projections in the package Oracle Spatial. When you use a SRID in a SDO_GEOMETRY, Oracle uses the SRID to interrogate the underlying tables (which SDO_ELLIPSOIDS is only one member) to get the properties of the projection for example the definition of the ellipsoid being a.

  I hope this helps at all.

  Don't forget to assign the points you like if our responses are considered correct or useful.

• Find the minimum distance between two SDO_GEOMETRY in Oracle Spatial?

  

  A circle (SDO_GEOMETRY)
  B - polygon (SDO_GEOMETRY)

  CASE:
  B contains A (or)
  The Interior of B.

  How to find the minimum distance between A and B in Oracle Spatial

  Hello guuid nameless person.

  What is

  my_answer := MDSYS.SDO_GEOM.SDO_DISTANCE(
     my_circle_geometry
    ,MDSYS.SDO_UTIL.POLYGONTOLINE(my_outer_polygon)
    ,my_tolerance
  );
  

  Now, you may need to pay attention to the holes in your polygon, would you the distance and an inner ring if it was closer to you?

  If the measure is only to outer rings, so something like

  my_answer := MDSYS.SDO_GEOM.SDO_DISTANCE(
     my_circle_geometry
    ,MDSYS.SDO_UTIL.POLYGONTOLINE(
        MDSYS.SDO_UTIL.EXTRACT(my_outer_polygon,1,1)
     )
    ,my_tolerance
  );
  

  And then also beware of the multipolygons as the foregoing only measured against the first polygon in the MultiPolygon.  You need to loop through the polygons of tests just the outer ring in this case.

  See you soon,.

• Oracle spatial any function interact

  Hi all

  I have a question about oracle spatial. I have a line (a path) and a type sdo_geometry polygon, and I used "all interact" function to find if the line intersects the polygon. Now I need to find how the trajectory crosses the polygon. For example, the path has 100 points and he in the polygon to 20th and out to the 70th point. Is it possible to find these points?

  Thank you

  Aswin

  Hi Aswin,

  Use SDO_GEOM. SDO_INTERSECTION. This will give you a line, and if your area is a simple box the line will have two points: the points of intersection of the line of origin with the boundary of the polygon. Of course, if your polygons have holes the result will be more than two points.

  HTH,

• Seeded data for Oracle Spatial 10 g

  I have a fundamental question about Oracle spatial. Oracle Spatial data seeded as US maps? For example, a store if I update the latitude and longitude, this information allows to know location and the city of the location.
  If Oracle Spatial has no data seeded, what options are available to implement the same in Oracle spatail.
  
  A quick response will be appreciated.
  
  Thank you

  Hello
  Space Oracle does not provide the content of the map. Some providers of content such as Navteq provides the specific format of map/routing/gecoding Oracle.
  If you want to discover the location (lat, lon) of an address, you can use Oracle geocode (sdo_gcdr.geocode).
  If you have a location (lat, lon) and you want to know the address information, use the geocoder Oracle (sdo_gcdr.reverse_geocode).

  Please see Chapter 14 SDO_GCDR package (geocoding) http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14255/toc.htm (Developer's guide space 10 gr 2)
