[Geoserver-users] WPS: Point in Polygon

[carrbrpoa]

I have implemented a custom WPS Process which returns a Geometry object
representing a Point.
What I need to do now is to chain this process with another (built-in one, I
guess) to answer the following question:

Within which polygon/feature (from a known published layer), if any, my
point is?

Unfortunately, I'm having a bad time trying to figure out the process that
will answer that question to me. Could you give me any direction about that?

Thanks

Hi,
that has an easy answer, it's difficult to find a process that does not
exist yet ;-)
You will have to implement it, it will be somehow similar to the clip one,
that
you can use as a reference:

https://github.com/geotools/geotools/blob/master/modules/unsupported/process-feature/src/main/java/org/geotools/process/vector/ClipProcess.java

Cheers
Andrea

Re: [Geoserver-users] Using both ColorMap and ContrastEnhancement in SLD?

[Simone Giannecchini]

Thinking...

it might work if you use the sld:ChannelSelection.

Something like:

Mind you, I have not tried it.

Re: [Geoserver-users] WPS: Point in Polygon

[carrbrpoa]

Hello,
I used your link and  this one
  
to figure out how to build a SimpleFeatureCollection and changed my custom
process to output it. Then, I could do what I needed by invoking the
built-in WPS Process vec:InsersectionFeatureCollection.

Thanks for your help!

[Geoserver-users] Updating raster statistics using REST API

[César Martínez Izquierdo]

I am trying to update the raster statistics of a geotiff coverage using the
REST API (as the statistics are not automatically filled by Geoserver
AFAIK).

I get the .json description of the coverage [1], update the statistics
values on it and send back the updated json [2] to Geoserver using a PUT
request (to URL
http://localhost:8080/geoserver/rest/workspaces/cesar/coveragestores/tmp_media_stats24/coverages/tmp_media_stats24.json
).

However, I only get a HTTP 500 error code:
 Debugging information 
cause-exception : java.lang.RuntimeException
cause-message   : null
class   : org.geotools.coverage.grid.GridGeometry2D
required-type   : org.geotools.coverage.grid.GridGeometry2D
converter-type  :
org.geoserver.config.util.XStreamPersister$GridGeometry2DConverter
line number : -1
class[1]: org.geoserver.catalog.impl.CoverageInfoImpl
converter-type[1]   :
org.geoserver.config.util.XStreamPersister$CoverageInfoConverter
version : 2.8.1
---

I've seen a similar problem on mailing lists [3] and tried the @class
workaround with no success (the error message looks different anyway).

Any idea?

Thanks in advance,

César Martínez

@class? Not sure what you mean.
Do you have the full stack trace for your error?

Judging by the error, it _could_ be related to the XXE vulnerability fix,
and might require someone
to add the GridGeometry2D class to the de-serialization whilelist here:
https://github.com/geoserver/geoserver/blob/master/src/main/src/main/java/org/geoserver/config/util/XStreamPersister.java#L467

[Geoserver-users] Odd error when zoomed out on Image Mosaic

[Russ Hore]

I had a working GeoServer 2.8.1 under Tomcat on Linux that had an error 
crashing when I tried to view layer groups in the admin interface.

I installed a second copy of GeoServer 2.8.1 under Tomcat at a different URL 
and copied across the raster data and created the layers I needed.

In the original system, I could view the whole of the UK 1:25k raster data.

Under the new system I get the error below until I zoom to 1:68k.
Any ideas what I am missing.
