This does look like a bug, probably introduced the last time I tried to fix
measure and Z coordinates

The issue exists with the latest Geotools version 33.2 when trying to read
this shape file.

Can you try with a supported version?

Re: [Geotools-gt2-users] Read Shape File: Invalid ordinate index: 3

[Ian T. <ijt...@gm...>]

Does your shapefile actually contain XYM points? Can you share the file or
at least the print out of the schema

[Geotools-gt2-users] Read Shape File: Invalid ordinate index: 3

[sunish <sun...@gm...>]

I am getting Invalid ordinate index: 3 Exception while reading a shape file.
Geotools Version: 28.2

I have this code for reading shape file features.  Please help.

private void fileDataStoreTest() {

        String filePath ="naksha_vadakara_build.shp";
        File file = new File(filePath);


        try {
            FileDataStore fileDataStore =
FileDataStoreFinder.getDataStore(file);


            Hints hints = new Hints(Hints.JTS_COORDINATE_SEQUENCE_FACTORY,
                    PackedCoordinateSequenceFactory.DOUBLE_FACTORY);

            System.out.println(fileDataStore.getSchema().getTypeName());
            System.out.println(fileDataStore.getSchema().getAttributeDescriptors());
            System.out.println(fileDataStore.getSchema().getCoordinateReferenceSystem());
            List<AttributeDescriptor> descriptors =
fileDataStore.getSchema().getAttributeDescriptors();
            for(AttributeDescriptor disc :descriptors ){
                System.out.println(disc.getLocalName()+"
"+disc.getType().getBinding().getSimpleName());
            }
            System.out.println(fileDataStore.getFeatureSource().getBounds());
            System.out.println(CRS.lookupEpsgCode(fileDataStore.getSchema().getCoordinateReferenceSystem(),true));

            SimpleFeatureSource src = fileDataStore.getFeatureSource();
            SimpleFeatureCollection col = src.getFeatures();
            SimpleFeatureIterator itr = col.features();
//            while (itr.hasNext()) {

                SimpleFeature f = itr.next();
                System.out.println(f.getDefaultGeometry().toString());

//            }
            itr.close();
            fileDataStore.dispose();

        } catch (IOException e) {
            throw new RuntimeException(e);
        } catch (FactoryException e) {
            throw new RuntimeException(e);
        }

    }

It is throwing this error.

Re: [Geotools-gt2-users] Issue when rendering coverages with bicubic interpolation

[Jody G. <jod...@gm...>]

 Hi Topias,

I am not close enough to this code to know if it is a bug, but I like that
your fix includes an example.

It would be preferable to know exactly where CRS.transform is producing a
null reference, perhaps by stepping through with a debugger, to determine
if that code could be made more robust. Your example does not show the same
request passing or failing based on interpolation method.

[Geotools-gt2-users] Issue when rendering coverages with bicubic interpolation

[Topias R. <top...@fl...>]

Hello,

I’m currently experiencing issues when rendering coverages with bicubic interpolation on GeoTools 32.1.

When rendering my coverage, the API returns a null reference, which per documentation would state that the coverage does not intersect the area to be rendered. However, if I disable interpolation, the area is rendered fine albeit the result is ugly.

I created a fork of the main repo and was able to reproduce the issue in unit tests. A simple CRS transformation would solve my issue, see the modified unit test and a fix for the rendering issue in here: https://github.com/FluiditLtd/geotools/commit/9a8fd3ebdb4321957c7f7dc10d290e36b25f7d04

My question is: Is this a bug? If this is indeed a bug, I can create a PR from the fork if the fix is deemed adequate.

Best regards,

Re: [Geotools-gt2-users] Working with GDAL and File Geodatabases

[Phil S. <P.S...@gn...>]

Thanks (I think) Andrea. Not very comforting. I am wanting this to work in a linux docker build. Good to know that I should not waste time on prebuilt binaries.   I like the geoserver approach. That seems the best long term solution and could be used as a docker layer so it doesn’t have to be built every time. However, this is clearly going to take me some time! Since my code already handles geopackage, I think I will add gdal, and then internally just convert geodatabase to gpkg. Ugly but should give me time to work out a direct gdb solution.

Hi Phil,

Setting up GDAL to work with GeoTools is sort of a dark magic art that few master, Linux distributions stopped
providing gdal-java bindings making a manual build almost the only option.

Even for the github action testing GDAL on Linux we pull a pre-built bridge library, a solution
that works for the time being, but won't last in the long run:
https://github.com/geotools/geotools/blob/main/.github/workflows/linux_gdal.yml#L23

The GeoServer docker image also has an example, in this case building everything from sources:
https://github.com/geoserver/docker/pull/138

I don't have a ready to use recipe regarding Windows... wondering if the https://gisinternals.com/ builds
have java support at all?

CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe:
That's probably my fault :-) GeoJSON parsing has moved to gt-geojson-core which along with the gt-geojson-store replaces the functionality in gt-geojson. The plan is at some point in the future to remove gt-geoson but currently GeoServer makes use of it (at least I think that was the problem) and I ran out of time and energy,

With gt-geoson-core you should be able to do something like this:


GeometryFactory gf = new GeometryFactory();
SimpleFeatureType type = DataUtilities.createType("test", "the_geom:Point:srid=4326");
SimpleFeatureBuilder builder = new SimpleFeatureBuilder(type);
builder.add(gf.createPoint(new Coordinate(1.23456789, 0.123456789)));
SimpleFeature feature = builder.buildFeature(null);
ByteArrayOutputStream out = new ByteArrayOutputStream();
GeoJSONWriter writer = new GeoJSONWriter(out);
writer.setMaxDecimals(6);

writer.write(feature);

Ultimately, what I am trying to do is read some features from a geopkg using geotools, fidding with contents of the feature and then writing the Feature to an ESRI FeatureServer using the REST API. Along the way, I have to get the geotools geometry converted to an ESRI Geometry class.
 The ESRI OGCGeometry (https://esri.github.io/geometry-api-java<https://esri.github.io/geometry-api-java%20can> can convert to ESRI geometry, but the fromGeoJson seems to be only method for creating a OGCGeometry.

What I am struggling with is getting a GeoJSON string out of geotools. I added gt-geojson module but can only see method for writing to file. Am I missing something blindingly obvious here? The documentation doesn’t seem up to date – pointing to methods that (eg GeoJSONWriter) that don’t exist (and pages 404 in the Javadoc).

Using 31.0

Also looking at option of using a WKT route instead.

[Geotools-gt2-users] Disable GDAL Metadata Parsing

[Stefan Z. <ste...@gm...>]

Hi

I want to read a geotiff file in a Spring Boot 3 application but get some
errors:

"java.lang.nullpointerexception: Cannot invoke
"javax.xml.bind.JAXBContext.createUnmarshaller()" because
"it.geosolutions.imageioimpl.plugins.tiff.gdal.GDALMetadataParser.CONTEXT"
is null"

Code is simple:

File file = new File("swissalti3d_2019_2614-1258_0.5_2056_5728.tif");

GeoTiffReader reader = new GeoTiffReader(file);
GridCoverage2D coverage = reader.read(null);
System.out.println(coverage.getEnvelope());

Is there a way to disable the gdal meta data parsing? I think there is some
clash with Spring Boot 3 using jakarta instead of javax.

regards
Stefan

that works for the time being, but won't last in the long run:
https://github.com/geotools/geotools/blob/main/.github/workflows/linux_gdal.yml#L23

The GeoServer docker image also has an example, in this case building
everything from sources:
https://github.com/geoserver/docker/pull/138

I don't have a ready to use recipe regarding Windows... wondering if the
https://gisinternals.com/ builds
have java support at all?

[Geotools-gt2-users] Working with GDAL and File Geodatabases

[Phil S. <P.S...@gn...>]

I am having something of nightmare setting this up. The documentation (33-snapshot) says GDAL 3.2  or OLDER. Puzzling? Downloading GDAL3.2 from gisinternals archive, I find gdalinfo –formats complaining about entrypoint for sqlite3 in the gdal302.dll after I set up all the path and environment variables  (and     OGRDataStoreFactory factory = new JniOGRDataStoreFactory(); dies with “java.lang.UnsatisfiedLinkError: C:\GDAL\gdal\java\gdalalljni.dll: The specified procedure could not be found” ). Is the documentation correct here?

With gt-geoson-core you should be able to do something like this:

writer.setMaxDecimals(6);

writer.write(feature);

Re: [Geotools-gt2-users] Trouble with parsing standalone XML file

[Jody G. <jod...@gm...>]

 How are you configuring the XMLConfiguration()?

Parser parser = new Parser(new XMLConfiguration());


You may want to make your own that knows about the different schemas used
in your file?

There is a lot of the details in the docs
<https://docs.geotools.org/latest/userguide/library/xml/internal/index.html>
.

Searching
<https://github.com/search?q=repo%3Ageotools%2Fgeotools%20SchemaResolver&type=code>
the codebase for SchemaResolver shows a couple examples:

            if (appSchemaResolver != null) {
                this.schemaParser.setResolver(appSchemaResolver);

I have not used this stuff in a bit; it would be helpful if you share your
results and we can improve the docs.

[Geotools-gt2-users] Trouble with parsing standalone XML file

[Finn V. <fin...@gm...>]

Hi there,

I am trying to parse some 3D city models and am running into issues. All
geotools dependencies are at 32.1. It follows a standalone XML file I am
trying to parse with a couple of `xsd` locations in the header.
https://gist.github.com/FiV0/91098e483ab993a3ef2293c12bd60afc#file-test-xml
and the way I am trying to parse it
https://gist.github.com/FiV0/91098e483ab993a3ef2293c12bd60afc#file-parserissue-java

There is no error but I am getting a bunch of warnings that some `xsd`
files can not be resolved and hence the returned result is not typed with
classes.
For example:
WARNING: Error loading schema for namespace:
http://www.opengis.net/citygml/building/1.0 at location:
http://repository.gdi-de.org/schemas/adv/citygml/building/1.0/buildingLoD1.xsd

Digging deeper, I tried to parse the schema directly with a custom
`CashingSchemaResolver` as follows:
https://gist.github.com/FiV0/91098e483ab993a3ef2293c12bd60afc#file-parsexsdfile-java
This results in a premature end of file error for a referenced schema. See
https://gist.github.com/FiV0/91098e483ab993a3ef2293c12bd60afc#file-error-txt

My second question concerns how I can actually set a custom schema resolver
on a parser. I tried to overwrite all kinds of methods on a custom
configuration, but all to no avail.
For example how would I set the following on my parser?
```
        SchemaResolver schemaResolver = new SchemaResolver(new
SchemaCache(new File ("/path/to/schema/catalog"), true));
```

Thank you,
Finn

 GeoTools use the JTS Topology Suite <https://locationtech.github.io/jts/>

Hi:

I have a "MultiLineString" layer which I want to do a buffer and dissolve

Does geotools support this out of box? If not, any alternative?

Re: [Geotools-gt2-users] PAMParser fails to create context in spring environment

[Jody G. <jod...@gm...>]

 It looks like you are missing JAXB-API?

This was included as part of the Java Enterprise Edition API, but in really
new versions of sprint I believe that will be replaced with Jakarta EE
Binding.

You will need to hang back at sprint 5.3 until such time as we can
modernize.

[Geotools-gt2-users] PAMParser fails to create context in spring environment

[<raf...@sa...>]

Hello!

First of all, thank you for GeoTools!

I have an issue with reading geotiff files in a Spring application.  
The app I am developing requires geotiff files to be read and for  
samples to be read at certain coordinates.

As of now, I am able to load a geotiff file with the GeoTiffReader and  
sample the position of interest using the GridCoverage. This works in  
a stand alone environment.

When I ported the same code to the app using Spring, the GeoTiffReader  
throws an exception while reading the geotiff file's metadata due to  
the CONTEXT in the PAMParser class being null.

After increasing the log level, the problem seems to start on the  
class initialisation. The JAXBContext fails to create a new instance  
of "it.geosolutions.imageio.pam" and throws the following exception:

PM javax.xml.bind.ContextFinder find

FINE: Trying to create the platform default provider

it.geosolutions.imageio.pam.PAMParser <clinit>

FINER: Implementation of JAXB-API has not been found on module path or  
classpath.

_javax.xml.bind.JAXBException_: Implementation of JAXB-API has not  
been found on module path or classpath.

- with linked exception:

[_java.lang.ClassNotFoundException_: com.sun.xml.bind.v2.ContextFactory]

at org.geotools.gce.geotiff.GeoTiffReader.<init>(_GeoTiffReader.java:275_)

at org.geotools.gce.geotiff.GeoTiffReader.<init>(_GeoTiffReader.java:199_)

I could not find the same issue or any info about this anywhere. It is  
still possible to query the GridCoverages created from these files,  
however no metadata is read.

Any help would be appreciated, thank you.
