• GML polygon holes and Oracle Spatial polygon those - different standards?

  Hi people,
  
  I'm working through some reflected in Oracle Spatial via 3 GML geometries validation issues. A small number of polygons is coming with 13349 errors. Looking closer I see all involve situations where there is a hole to touch the outer ring at a single point. GML is representative this hole in the outer ring. Here's an example simplified with bad ascii art (be nice if the forum was a way to post pictures):

   A----------B
   |..........|
   E----F.....|
   |\   |.....|
   |.\  |.....|
   |..\ |.....|
   |....G.....|
   |..........|
   D----------C

  A valid Oracle Spatial polygon would be an outer ring of A.B, C, D, E, A and the inner ring of E, F, G, E.
  However, the GML arrived like a ring outside of A, B, C, D, E, G, F, E, A, who once loaded into Oracle Spatial up 13349 error. SDO_UTIL. FROM_GML311GEOMETRY does not resolve this error but goes right through.
  
  I spent some time on the documentation of GML, and it does not seem that the standard GML polygon expressly rules on the matter. This document,
  http://www.gdmc.nl/publications/2004/Invalid_Valid_Clean_Polygons.PDF
  seems to confirm this assertion. When we talk about ISO 19107, which forms the basis of the subject polygon GML, the author says in addition, "it is not directly obvious if the outer limit is allowed to touch itself or if it is allowed to touch the inner limits and if so, under what conditions it could."
  Is - it sounds good to you all?
  Note that the WKT specification does not actually say that these holes must be the same stored in Oracle Spatial. Therefore, one question GML.
  
  So assuming the GML specification allows the storage of polygons with holes of the two types, it seems we until his side Oracle Spatial things to correct the situation, when we meet it? I would suggest that perhaps SDO_UTIL. FROM_GML311GEOMETRY should detect and solve this problem as a matter of course, but I know the issue of rotation ring WKT (SDO_UTIL.) FROM_WKTGEOMETRY seems to ignore the ring rotation Oracle Spatial position is that these incoming error correction is the individual user to address problem. Anyone have any ideas on the issue?
  
  Note This SDO_UTIL. RECTIFY_GEOMETRY does not seem to solve the problem. I need to write a wrapper to walk the vertices of the ring and sniff for summits in double and then redeploy a hole when the situation is. Am I missing something?
  
  Thank you and happy Friday,
  
  Paul

  Paul,

  Frankly, we didn't expect the GML definition differs from that of the simple feature specification that complies
  with the Spatial model. If we had never expected this problem.

  Anyway, the sdo_util.rectify_geometry () should solve the problem depending on your version of database.
  Otherwise, try self-union with the call to sdo_geom.sdo_union () and it should fix the geometry to make a polygon
  with an exterior and an inner ring.

• 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.

• Oracle spatial in ArcSDE

  I am new to oracle spatial and GIS in general. I have a customer who requires diapers space oracle to create in the environment of ESRI ArcSDE.

  anyone can guide me please?

  Hello

  When you create a new class of functionality using ArcCatalog (ESRI ArcGIS Desktop software), you can set the configuration to "SDO_GEOMETRY. This new layer will be saved with ArcSDE system tables and stored in an oracle spatial format.

  of course, you must have activated in your Oracle Spatial database.

• 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.

  If Oracle Spatial has no data seeded, what options are available to implement the same in Oracle spatail.

  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).

  How to load this .xls in oracle and transform the place in sdo_geometry

  Hello
  You can use sql loader or an external table to import your data.
  As your location data are in WKT format, it will be easier to use a temp. table (tmp_obj_loc).
  It might be easier to add ',' as delimiters between each column in your data.

  The following example uses sqlldr (the temporary table can be created as an external table):

  -- create a temp. table to hold your location info.
  drop table tmp_obj_loc ;
  
  create table tmp_obj_loc (
  obj varchar(20),
  loc varchar2(200)
  );
  

  -- sqlldr example
  -- use a control file if needed
  -- this creates the temp table

  load data

• Package oracle.spatial does not exist in NetBeans

  Hi all,
  
  I installed Oracle 11 g R2. I installed Netbeans 6.8. Everything on Red Hat Enterprise 5.
  I am doing a project in Netbeans using the oracle.spatial package. So I imported this package if:
  
  Oracle.spatial import. *;
  
  But netbeans says that this package does not exist.
  
  
  Listening port is active.
  Database is in place.
  NetBeans is already connected to Oracle with driver oracle.jdbc.OracleDriver.
  I put the classpath in the project: I added the ojdbc6.jar of jar file in the project libraries.
  
  What do you think of this problem?
  
  
  Thanks in advance for the help.

  I don't know much about Java. But I am sure that there should be a utility that can help you locate the jar file where oracle spatial package exists. You can add this JARto your classpath or something.
