Sdo_geom.validate_geometry_with_context

I have been using sdo_geom.validate_geometry_with_context to identify problems with geometry. When reporting errors the function returns, if one exists, an error code and the position of the error.
Does anyone know whether the validation stops at this point, i.e. it does not continue through the remainder of the geometry to find further errors?

The function SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT will validate a single geometry. You can write a PL/SQL cursor to validate each geometry in a table if you desire.
You can validate all the geometries in a table with SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT, and the results are written to a table.
See the Oracle Spatial Users Guide and Reference, Release 9.2 for further information

Sdo_geom.validate_geometry_with_context returns error for a valid polygon

Hi people,
I have found a strange case, where sdo_geom.validate_geometry_with_context returns an error:
select sdo_geom.validate_geometry_with_context(SDO_GEOMETRY(2003, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 1003, 1), SDO_ORDINATE_ARRAY(0.0, 51.9273, 0.3556, 51.9273, 0.3910, 51.9274, 0.1964, 51.9274, 0.0, 51.9273)), 1) from dual;
13349 [Element <1>] [Ring <1>][Edge <3>][Edge <1>]
The tolerance for SRID 8307 is in meters, right? The shape is a parallelogram, although the lat dimension is about 0.0001 grad or ~11 meters. Any hints why there is an error?

You defined a spheric polygon in WGS84, that has a self intersection near <0.22945371630245; 51.9274226210077> :
WITH l1 AS
(SELECT SDO_GEOMETRY(2002, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1), SDO_ORDINATE_ARRAY(0.0000,51.9273, 0.3556,51.9273)) geom

Using SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT effectively

I have been using SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT to validate the geometry of several million polygon features. Here is an example of the SQL I have been using:
Create table myResultsTable
as
SELECT A.myID, SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(A.GEOMETRY, 0.1) as invalidGeometry, FROM myGeometryTable A
WHERE SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(A.GEOMETRY, 0.1) <> 'TRUE';
I noticed that for each polygon in the table, this function returns only one result for the polygon before moving on to the next polygon despite it being possible that a polygon could fail the validation for several reasons.
How can I return all reasons why a polygon has invalid geometry?
Does it require me to use PL/SQL? If so, can anyone get me started?
Or does it require me to use SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT? If so, how do I specify a tolerance when using this function like I did when I used SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT?
Many thanks for your time.

Hi,
The validation routines only report the first reason geometry data is invalid.
To validate several million polygon features I would use validate_layer_with_context because it is faster.
If you don't want to for some reason then alter your statement to only run the validation procedure once:
select a.status,a.id
from (SELECT m.myID id, SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(m.GEOMETRY, 0.1) status
FROM myGeometryTable m) a
where a.status <> 'TRUE';
Then there are possibilities in terms of automatically trying to fix things up to move on to the next error. For instance, if you get a duplicate vertices error your run remove_duplicate_vertices to try to fix that error, then revalidate and see if there are other errors. If you have a self-intersecting geometrt then running a self union may fix those kinds of problems (in 10g r2 this is automated with sdo_util.rectify_geometry, which attempts to automatically fix these kinds of errors).
NOTE: Always check results of any automated geometry fix-up procedures to make sure you agree with the results of the procedure. I would recommend against automatically updating your data without checking the results.
Hope this helps,
Dan

SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT giving seemingly incorrect result

I ran the following query and got the unexpected answer of TRUE:

What surprised me was the SDO_ORDINATE_ARRAY after the remove duplicates has only a longitude and latitude yet the geometry a line was validated as true. Doesn't a line at least need two sets of coordinates? How was this geometry validated to true?

yet the geometry a line was validated as true.Actually a geometry line containing duplicates was converted to a point type (gtype 2001), which was validated as 'TRUE' as it should be.

Sdo_geom.validate_geometry_with_context - Reporting multiple errors

All Oracle versions.
sdo_geom.validate_geometry_with_context appears to report only the first error it finds in an sdo_geometry.
Thus, it reports only the first duplicate vertex in "ORA-13356: adjacent points in a geometry are redundant", or only
the first loop in a ring for "ORA-13349: polygon boundary crosses itself".
I understand that, for some errors, reporting more than one error would be difficult but for more simple errors such as
the two mentioned, it would be most helpful to have validate_geometry_with_context report more than one error location
in its return string. Such reporting would reduce the time and effort required in find-fix-find error correction cycle.
Comments?

Simon

A triangle is a bad example for ORA-13349. In fact, it is impossible for a triangle not to be right unless two points are the same.
I don't agree with a lot of the comments because I know that many simple types of errors can be detected. Here is
a polygon with a hole that has multiple 13349 errors because of "bow-ties" or "loops in the outer boundary".

software packages provide such capability so it is possible. And, these are data-level issues so I think it reasonable that Oracle
provides an improved set of functions and not hand it over to external GIS software clients.

SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT returns ORA-13199 SRID does not exist

Hi everyone,
I'm facing with this error while I was trying to list wrong spatial data (11.0.2.0.3 RAC (AIX))
Select   *

Is there anyone who faced with this kind of issue or any idea ?

There is no such SRID 2000303. However, this one sure looks like it does the same thing. Replace all the SRID values with 2320 and you should be set.

SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT for polygon geometry validation

Hi,
I would like to make a validation of the polygon geometry upon a table SCHEMA.TABLE with the GEOM field, where the geometry is stored.
Can someone help me with a sample SQL sentence to fill my SCHEMA.VALIDITY table with all the detected errors that occured in the SCHEMA.TABLE?
Thanks!

Have you tried scrolling down to the bottom of that section? You will see the following example (as in all descriptions in the documentation):
Examples*
The following example validates the geometry objects stored in the SHAPE column of the COLA_MARKETS table. The example includes the creation of the result table. For this example, a deliberately invalid geometry was inserted into the table before the validation was performed.
-- Is a layer valid? (First, create the result table.)
CREATE TABLE val_results (sdo_rowid ROWID, result varchar2(1000));
-- (Next statement must be on one command line.)
CALL SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT('COLA_MARKETS','SHAPE','VAL_RESULTS');
Call completed.

CREATE TABLE val_results (sdo_rowid ROWID, result varchar2(1000));
would have been in your case:
CREATE TABLE schema.validity (sdo_rowid ROWID, result varchar2(1000));
CALL SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT('COLA_MARKETS','SHAPE','VAL_RESULTS');
would have been in your case:
CALL SDO_GEOM.VALIDATE_LAYER_WITH_CONTEXT('SCHEMA.TABLE','GEOM','SCHEMA.VALIDITY');
SQL> SELECT * from val_results;
would have been in your case:
SELECT * from schema.validity;
If you would like to have your id included:
Select a.id, b.*
from schema.validity b left outer join schema.table a
on (b.sdo_rowid= a.rowid);
In order to help people making their life easier with the management of spatial metadata, spatial index and geometry validation, like yours, and possible fix up, 1Spatial has a product named Radius Check.
Have a look at the second item from the top here: http://www.oracle.com/technology/products/spatial/htdocs/spatial_partners_downloads.html

Error on SDO_GEOM.RELATE

I get this error on this statement:
if SDO_GEOM.RELATE(Pic1,'anyinteract',Pic2,0.0000005)='TRUE'
then
The error i get is the following:
ORA-13050: unable to construct spatial object
ORA-06512: at MDSYS.SDO_3GL
ORA-06512: at MDSYS.MD2
Where can i do?

The most likely cause is that an instance of Pic1 or Pic2 is invalid. Run sdo_geom.validate_geometry_with_context() and if any geometries are invalid, fix or delte them.

Something wrong with sdo_geom.sdo_intersection function

I have two geometries. Both of them are valid in all tolerances, I tested.
The relation between geometries is OVERLAPBDYINTERSECT.
I run the sdo_geom.sdo_intersection with parameters - both of geometries and as result there is geometry which relation with second geom is again OVERLAPBDYINTERSECT.
IMHO, the relation MUST be COVEREDBY.
The error occurs rarely, but this is a real problem.

Hi,
This is definitely a precision issue and due to the numerical stability problem
very slight differences in coordinates is resulting in OVERLAPBDYINTERSECT
instead of COVERS.
Since you have many digits after the decimal in the input data, the tolerance you are
specifying may not work for all pairs of geometries.
For example, lets say you have vertices from geometry A as a1, ... aN and vertices
from B as b1 ... bN.
When each geometry is validated at a given tolerance there is no problem.
But when you put two geometries together, the tolerance you specify many be
valid for the combination of those two.
For example, when these two geometries share an edge, the vertices might not
align exactly.
So you will have line segments which are made up of vertices from both geometries
like: a1 b3 a2 b4 ...
In such cases, the distance between a1 and b3 might be less than the tolerance you
specified so we have to internally adjust the tolerance.
As a result, the intersection might have been computed at a lesser tolerance than the
one you specified (i.e. 0.00005 could be changed to 0.000005).
So when you try to do RELATE again with 0.00005, the result is slightly off due
to the tolerance difference.
The best option in this case is to look for some slightly relaxed constraint than to check
for the exact COVEREDBY/COVERS relationship with the intersection geometry.
There are other factors such as lost precision (very minor) due to conversion from floating point double to oracle NUMBER and vice versa which may change a COVERS
to OVERLAPBDYINTERSECT since you have many digits after decimal
in the input data.

Simple geometry gets ORA-29532 error on all SDO_GEOM calls

Hi all,
I have a single point in a table such that the query:
select SDO_GEOM.VALIDATE_GEOMETRY(geomObj, 0.05) from testvalid;
/* Returns */
SDO_GEOM.VALIDATE_GEOMETRY(GEOMOBJ,0.05)
'TRUE'However the query:
select SDO_GEOM.VALIDATE_GEOMETRY_with_context(geomObj, 0.05) from testvalid;Receives the following error:
ORA-29532: Java call terminated by uncaught Java exception: java.lang.NumberFormatException: empty String
ORA-06512: at "MDSYS.SDO_3GL", line 658
ORA-06512: at "MDSYS.SDO_GEOM", line 519
ORA-06512: at "MDSYS.SDO_GEOM", line 558
ORA-06512: at line 1The data itself is a single sdo_point:
select GEOMOBJ from testvalid;
/* Returns: */
GEOMOBJ
'(3001, , (174.092329032787, 129.420551704918, -71.2857142857142), , )'I think that the problem is something to do with the precision of the stored X, Y and Z values in the point because if I run the following:
update TESTVALID set GEOMOBJ.sdo_point.x = cast(GEOMOBJ.sdo_point.x as number(8,3));
select SDO_GEOM.VALIDATE_GEOMETRY_with_context(geomObj, 0.05) from testvalid;
/* Returns: */
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(GEOMOBJ,0.05)
'TRUE'Similarly, running a direct comparison from an object made on the fly from the point's text representation works fine:
select SDO_GEOM.VALIDATE_GEOMETRY_with_context("MDSYS"."SDO_GEOMETRY"(3001,NULL, "MDSYS"."SDO_POINT_TYPE"(174.092329032787,129.420551704918,-71.2857142857142),NULL,NULL), 0.005) from dual;
/* Returns */
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT("MDSYS"."SDO_GEOMETRY"(3001,NULL,"MDSYS"."SDO_POINT_TYPE"(174.092329032787,129.420551704918,-71.2857142857142),NULL,NULL),0.005)
'TRUE'Note that I only noticed this problem after upgrading from v11 to v11 R2. Also, the same ORA-29532 error comes up when running any of the SDO_GEOM.[x] function calls such as SDO_GEOM.DISTANCE(). The problem is not limited to SDO_POINT type geometries, yet the problem occurs only on some geometry entries in my database. It is repeatable in that the same geometry will continue to fail and the only solution I've found is to try to round down its precision in x, y, and/or z. I only know how to easily round down the precision for SDO_POINT types, so one of my problems is that I'm left with a whole scattering of other geometries that I can no longer spatially query.
The datas themselves were inserted from MATLAB (which connects using v11 Oracle ODBC Java drivers) which converts my coordinates to java.math.BigDecimal and binds them to an oracle prepared statement.
One possibility that I'm considering is that the insertion is done from various computers, some of which are 64-bit machines. Maybe somehow those machines are pumping in coordinates to a precision too great for oracle geometry?
Any help would be fantastic as I'm pretty lost here.
If the precision is indeed the problem, does anyone know how I can trim off those excess values after the decimal point for all geometry types?
Thanks,
Sven.

The problem is with the way the ordiantes are created via java programs pre 11.2.
There was a bit alignment problem in the internal representation of the number when these numbers are created from a java program.
In 11.2 this corruption is fixed, but as a result the data that is already corrupted gives this "empty string" error.
It is very easy to fix. Follow the steps in the script below.
create or replace function id_geom ( g in sdo_geometry)
return sdo_geometry deterministic as
g1 sdo_geometry ;
idx number;
ords sdo_ordinate_array;
x number;
y number;
z number;
point_t sdo_point_type;
begin
if (g.sdo_point is not NULL) then
x := NULL; y := NULL; z := NULL;
if (g.sdo_point.x is not NULL) then
x := g.sdo_point.x * 10;
x := x / 10;
end if;
if (g.sdo_point.y is not NULL) then
y := g.sdo_point.y * 10;
y := y / 10;
end if;
if (g.sdo_point.z is not NULL) then
z := g.sdo_point.z * 10;
z := z / 10;
end if;
point_t := SDO_POINT_TYPE(x,y,z);
else
point_t := NULL;
end if;
if (g.sdo_ordinates is not NULL) then
ords := sdo_ordinate_array();
ords.extend(g.sdo_ordinates.count);
for idx in 1 .. ords.count loop
x := g.sdo_ordinates(idx);
x := (x*10.0);
x := x/10.0;
ords(idx) := x;
end loop;
g1 := sdo_geometry(g.sdo_gtype, g.sdo_srid,point_t,g.sdo_elem_info,ords);
else
g1 := sdo_geometry(g.sdo_gtype, g.sdo_srid,point_t,g.sdo_elem_info, NULL);
end if;
return g1;
end;
And then update the rows with geometry data with SQL like this:
update geom_table set geom = id_geom(geom);

SDO_AGGR_SET_UNION fails but SDO_GEOM.SDO_UNION succeeds.

Hi folks,
Happy Thanksgivings all. I have an aggregation task that seemed ideal to try out the new SDO_AGGR_SET_UNION function in 11gR2 (11.2.0.2). I have two valid touching polygons (amongst many others) that validate at 0.05 meter tolerance. When I union them together using SDO_GEOM.SDO_UNION or the original SDO_AGGR_UNION the results look great and the area of the new polygon is close to the two inputs. However when I run the exact same polygons through SDO_AGGR_SET_UNION I get back failed results - e.g. a 2004 containing one input polygon and a random point geometry from the boundary of the other polygon.
Aggregation errors like this aren't exactly anything unheard of in Oracle Spatial and normally I'd just submit it as a bug. But I am a bit confused when the usual SDO_UNION functions works just fine but the new SDO_AGGR_SET_UNION function fails. Aren't they working off the same codebase? I've always assumed that what works for SDO_UNION would work for SDO_AGGR_UNION and now SDO_AGGR_SET_UNION is just another addition to the family of "unioners". Do we need to treat (and test) the new SDO_AGGR_SET_UNION as a different critter altogether from SDO_UNION? My apologies if that drifts into proprietary taboo land. Looking at the results of my test again I see that in fact SDO_AGGR_UNION does not EXACTLY match SDO_UNION (darn close though) so perhaps the family idea is all wrong?
My opinion at this point is confused about whether to use SDO_AGGR_SET_UNION. It is much faster and much easier on the PGA I'l will admit, but SDO_UNION wins the quality award for this task.
Cheers and Happy Holidays,
Paul

Hi Paul,
I'm not sure where you see the mistake.
I run your script on Version 11.2.0.1 (function sdo_aggr_set_union is already here) and get the following result:
polygon1 validation at ,05 = TRUE
polygon2 validation at ,05 = TRUE
combined area is 34338292,4039011
sdo_union creates GTYPE 2003
sdo_aggr_union creates GTYPE 2003
sdo_aggr_set_union creates GTYPE 2003
sdo_union creates area of 34338291,3352027
sdo_aggr_union creates area of 34338293,6868519
sdo_aggr_set_union creates area of 34338291,3352027
The area of sdo_union and sdo_aggr_set_union are the same. Can you please point out, where your problem is exactly? Maybe in 11.2.0.1 the function was different?

SDO_GEOM.SDO_BUFFER failed with ORA-13050

Hello,
I want to construct buffer for polylines.
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT function returns TRUE for problem geometries:
SELECT SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(
MDSYS.SDO_GEOMETRY(2002, NULL, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 2, 1), MDSYS.S

from dual
SDO_GEOM.VALIDATE_GEOMETRY_WIT
TRUE
But SDO_BUFFER fails:
SELECT SDO_GEOM.SDO_BUFFER(
MDSYS.SDO_GEOMETRY(2002, NULL, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 2, 1), MDSYS.SDO_ORDINATE_ARRAY(

121.75232, 31.37518, 121.74977, 31.37854)), 1e-5, 1e-7)
from dual;
Can somebody help me with advice how to construct buffer?
I have SDO_VERSION=9.2.0.5.0
Data tolerance in the user_sdo_geom_metadata table is 1e-7.
Thank you.
PS:
Other example of problem polyline:
MDSYS.SDO_GEOMETRY(2002, NULL, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 2, 1), MDSYS.SDO_ORDINATE_ARRAY(

Hello.
Im still trying to find out resolution for buffers construction :)
Actually I've got that buffer construction works much better on geodesic data.
Next statement is OK now:
SELECT SDO_GEOM.SDO_BUFFER(
MDSYS.SDO_GEOMETRY(2002, 8307, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 2, 1), MDSYS.SDO_ORDINATE_ARRAY(
121.75439, 31.37049, 121.75234, 31.36996, 121.75245, 31.37184, 121.75262, 31.37362, 121.75253, 31.37449,
121.75232, 31.37518, 121.74977, 31.37854)), 1, 1e-2, 'arc_tolerance=0.5')
from dual;
I run large test and got only one (currently) issue with the next poliline [ORA-13050: unable to construct spatial object]:
select SDO_GEOM.SDO_BUFFER(
MDSYS.SDO_GEOMETRY(2002, 8307, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 2, 1), MDSYS.SDO_ORDINATE_ARRAY(
117.56163, 23.74977999, 117.56163, 23.74949001, 117.56163, 23.7492, 117.56117999, 23.74906)),
1, 1e-2, 'arc_tolerance=0.5') from dual;
What is wrong with that poliline?
Are there any rules or workarounds for such cases? Can some body suggest me something about that?
I've found only 2 workarounds for that time:
1) I need to construct buffer within 1 millimeter tolerance. So I can round input geometry ordinates to 1 millimeter (1e-7) and try to build buffer after that. I did it for above poliline - and it works (actually it is necessary to round only second ordinate 23.74977999->23.7497799). But I don't sure that it will resolve issue entirely.
2) I can iteratively slightly increase buffer distance until buffer construction will be OK. Above example works starting from 1.3 meter. It is not best resolution because it can alter process logic.
Thank you.

How find the errors (sdo_geom.validate TRUE) in objects

Hi, I've many layers of polygons with topologycal errors (loaded from Mapinfo 7.5 , the function sdo_geom.validate_geometry_with_context give error 13349, probably there are some ring, edge etc...
But there is a metod, program, utility to find where the errors are to correct them?

Fabio,
Error 13349 indicates that the polygons intersect with themselves.
You need to fix these errors. There are tools in MapInfo Professional 7.5 to check and automatically fix them. There are other tools commercially available which also fix geometry errors.
If you know MapInfo I would fix these errors there.
