When a new GTRasterLayer is created in the method 'GTRasterLayer::create()', its Envelope is calculated from the AnalysisExtent parameter.

The 'AnalysisExtent::getHeight()' return the Zrange of the Extent, then the envelope misses the ymax member.

See...

This code fixes the bug...

double width = ge.getXMax() - ge.getXMin(); double height = ge.getYMax() - ge.getYMin(); final Envelope envelope = new Envelope2D((CoordinateReferenceSystem) crs, ge.getXMin(), ge.getYMin(), width, height);
