Spatial :: Parameters For 2D Affine Transformation

Jul 13, 2012

I have the following parameters for 2D affine transformation:

Two translation:
tx=2754.3661 and ty = -237.0731
and rotation in radians: -.001016214498072193185827329

Is this specification correct:

SDO_UTIL.TO_WKTGEOMETRY(SDO_UTIL.AffineTransforms (
geometry =>myGeometry,
translation => 'TRUE', tx => 2754.3661, ty => -237.0731, tz => 0.0,
scaling => 'FALSE', psc1 => NULL, sx => 0.0, sy => 0.0, sz => 0.0,
rotation => 'TRUE',
p1 => MDSYS.SDO_GEOMETRY(2001, NULL, MDSYS.SDO_POINT_TYPE(0, 0, NULL), NULL, NULL), line1 => NULL,
angle => -.001016214498072193185827329,
dir => -1,
shearing => 'FALSE', shxy => 0.0, shyx => 0.0, shxz => 0.0, shzx => 0.0, shyz => 0.0, shzy => 0.0,
reflection => 'FALSE', pref => NULL, lineR => NULL, dirR => -1, planeR => 'FALSE', n => NULL, bigD => NULL
))

BTW, in PostGIS it works correctly: ST_Affine (myGeometry, cos(rotation), sin(rotation), -sin(rotation), cos(rotation), tx, ty));

Spatial :: ORACLE 11g Spatial And GRS 80

Apr 4, 2013

I am working on a project that will require both projected coordinates and geographic coordinates for different product files coming in. I have no issues defining, storing, extracting or matching the geographic coordinates. My columns for those coordinates with SRID 8307 are defined in the 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: create index "MYDB"."INVGEO_IDX" on "MYDB"."INVENTORYGEOMETRY"("INVGEO") indextype is MDSYS.SPATIAL_INDEX;

how I am going to have a column that has both Geographic and Projected coordinates. Am I allowed to define more SDO_DIM_ELEMENT(s) fro the SDO_DIM_ARRAY with different min/max values. As an example, would I be able to still use an SRID of 8307 for both WGS 84 and GRS80 data (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('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? Also, I don't know the relationship between the SDO_ELLIPSOIDS table and the SDO_GEOMETRY table.

how I'm going to make this work for both the geographic and projected coordinates or if I'm going to be able to make it work.

Quick Data Transformation

Jun 10, 2013

if mytable.col1 is not blank, then copy mytable.col1 to mytable.col2 BUT, it needs reformatting during the copy. Both columns are varchar2 col1 being 15 wide and col2 being 20 wide.

I need to transform from 'PACKAGEabcde001' to 'PACKAGEabcde 00001'

so yes, those 5 extra characters are indeed 3 spaces and 2 extra zero's.

SQL & PL/SQL :: Data Transformation / Remodel Some Data For Processing

Feb 6, 2011

I am trying to remodel some data for processing, as unfortunately the original data structure is unsuitable.

My requirements are to recreate the data as a view which can then be query'd directly by the client, and therefore would like to encapsulate all the required transformation within one SQL query.Here is a sample of the table structure i'm faced with:

SQL>
SQL> l
1 create table insane
2 (
3 dept number not null,
4 firstname varchar2(30),
5 surname varchar2(30),
6 city varchar2(30),
[code]....

So, i'd like to be able to turn this on it's head and come out with data that looks something like this (which, for the purpose of this example, is fabricated manually):

SQL> select * from sane
2 /

DEPT_ID PERSON_ID FIRSTNAME
---------- ---------- ------------------------------
SURNAME CITY
------------------------------ ------------------------------
1 30 Peabo
[code]....

We get 99.925 meters,and not the 198.075 that we were expecting.

Spatial :: How To Disable Triggers Per Session

Mar 1, 2013

I recently stumbled upon a post for an undocumented golden gate procedure that I find VERY useful when repairing / simplifying spatial data as a DBA without causing user triggers to fire and do unnecessary work, etc. Anything with foo in the name must be good, right? ;-)

HINT: Oracle please make this a documented feature!

This will disable triggers – just for a session – no system wide changes or trigger mods needed! Yes, fire needs to be set to true - to disable the triggers from firing.

exec sys.dbms_xstream_gg.set_foo_trigger_session_contxt(fire=>true);

Note, you will need execute permissions on sys.dbms_xstream_gg first.See for more info: URL.....

Spatial :: Adding Missing EPSG For Austria?

May 21, 2013

I am using Oracle Database 11.2.0.1 with activated Oracle Locator and I'm wondering why there are missing EPSG-Codes in SDO_COORD_REF_SYSTEM. I thought, implementing the EPSG-Scheme means adding all supported projections.

Since I need to use the coordinate systems for austria (especially 31256) , which have been reassigned new* EPSG-Codes (31251-31259) with new false northing in 2007, it is a problem that in Oracle Locator only the "old" codes (31281-31290) are supported.

Do I have to add these codes manually or is there a patch available?

Spatial :: Error While Executing Oracle Query From C#

I am trying to execute an inline spatial query from c# using ODP.NET. This is a select query and I am passing 2 parameters to this query, one is string and other one is SDO_GEOMETRY. I am able to send SDO_Geometry parameter from c# using Oracle UDT custom designed classes.

Query is working as intended but occasionally giving the following errors:

ORA-29902: error in executing ODCIIndexStart() routine
ORA-13033: Invalid data in the SDO_ELEM_INFO_ARRAY in SDO_GEOMETRY object
ORA-06512: at "MDSYS.SDO_INDEX_METHOD_10I", line 333

I could not figure out the cause of this issue (as it is not failing frequently). Am i getting this issue with the actual query or with Oracle UDT conversion.

Spatial :: How To Get All The Values Of The SDO_ORDINATE_ARRAY Of A Oriented Point

Dec 14, 2012

I'm trying to get the values of a Geometry which is an Oriented Point. To that, i'm using SDO_UTIL.GETVERTICES, but this utility only obtains the point X,Y, it doesn't obtain the values of the orientation vector.

The Geometry is this:
MDSYS.SDO_GEOMETRY(
2001,8307,NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1,1,1,3,1,0),
MDSYS.SDO_ORDINATE_ARRAY(-75.586088632813272,6.1794352615514194,0.57278169530235967,-0.81970795380217887,0)
)

The query is this:
SELECT c.ipid, c.nombre, t.X, t.Y, t.Z, t.W
FROM Hidrantes c,
TABLE(SDO_UTIL.GETVERTICES(c.geometria)) t
where c.ipid = 4691117
ORDER BY c.ipid, t.id;

Result:
4691117          -75,5860886328133     6,17943526155142          (null) (null)

As you can see, it only obtains the X,Y values but not the values of the orientation vector, how can I get the values?

Spatial :: Convert Multi-line To Simple Line

Feb 13, 2013

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0

We are processing spatial data from another source to display in our GIS environment. The data is a set of multi lines. The gtype is 2006. A typical geometry looks like:

SDO_GTYPE     2006
SDO_SRID      31370
SDO_POINT.X   NULL     
SDO_POINT.Y   NULL
SDO_POINT.Z   NULL
SDO_ELEM_INFO (1,2,1, 7,2,1)
SDO_ORDINATES (105094.84, 195084.96,
105094.54, 195080.22,
105094.84, 195084.96,
105094.84, 195084.96,
105094.68, 195082.47 )

Now, this is not an actual multiline... it's just encoded as a multi line, but if you look at the coordinates you'll see that the end point of the first line is the same as the beginning of the second line (105094.84, 195084.96).

A better way to encode this geometry would be:

SDO_GTYPE     2002 <---
SDO_SRID      31370
SDO_POINT.X   NULL     
SDO_POINT.Y   NULL
SDO_POINT.Z   NULL
SDO_ELEM_INFO (1,2,1)
SDO_ORDINATES (105094.84, 195084.96,
105094.54, 195080.22,
105094.84, 195084.96, <---
105094.68, 195082.47 )

Is there a standard function in Oracle that does this conversion for me? Or do I have to write my own :)
