I try to resample a sentinel 2a image in 10m resolution and I get the following error message java.lang.RuntimeException: Cannot construct DataBuffer. at com.sun.media.jai.util.DataBufferUtils.constructDataBuffer(DataBufferUtils.java:132) at com.sun.media.jai.util.DataBufferUtils.createDataBufferDouble(DataBufferUtils.java:293) at javax.media.jai.ComponentSampleModelJAI.createDataBuffer(ComponentSampleModelJAI.java:274) at javax.media.jai.RecyclingTileFactory.createTile(RecyclingTileFactory.java:389) at javax.media.jai.PlanarImage.createWritableRaster(PlanarImage.java:1982) at javax.media.jai.ScaleOpImage.computeTile(ScaleOpImage.java:1065) at com.sun.media.jai.util.SunTileScheduler.scheduleTile(SunTileScheduler.java:904) Caused: org.esa.snap.core.gpf.OperatorException: Cannot construct DataBuffer. at org.esa.snap.core.gpf.internal.OperatorExecutor$GPFImagingListener.errorOccurred(OperatorExecutor.java:375) at com.sun.media.jai.util.SunTileScheduler.sendExceptionToListener(SunTileScheduler.java:1646) at com.sun.media.jai.util.SunTileScheduler.scheduleTile(SunTileScheduler.java:921) at javax.media.jai.OpImage.getTile(OpImage.java:1129) at com.sun.media.jai.opimage.CropOpImage.getTile(CropOpImage.java:122) at javax.media.jai.RenderedOp.getTile(RenderedOp.java:2257) at javax.media.jai.PointOpImage.computeTile(PointOpImage.java:911) at com.sun.media.jai.util.SunTileScheduler.scheduleTile(SunTileScheduler.java:904) at javax.media.jai.OpImage.getTile(OpImage.java:1129) at javax.media.jai.PlanarImage.getData(PlanarImage.java:2085) at com.bc.ceres.glevel.MultiLevelImage.getData(MultiLevelImage.java:64) at org.esa.snap.core.gpf.internal.OperatorContext.getSourceTile(OperatorContext.java:406) at org.esa.snap.core.gpf.internal.OperatorContext.getSourceTile(OperatorContext.java:392) at org.esa.snap.core.gpf.internal.OperatorImage.computeRect(OperatorImage.java:73) at javax.media.jai.SourcelessOpImage.computeTile(SourcelessOpImage.java:137) at com.sun.media.jai.util.SunTileScheduler.scheduleTile(SunTileScheduler.java:904) at javax.media.jai.OpImage.getTile(OpImage.java:1129) at com.sun.media.jai.util.RequestJob.compute(SunTileScheduler.java:247) [catch] at com.sun.media.jai.util.WorkerThread.run(SunTileScheduler.java:468)
Yes, this should be enough.
Can you show me the configuration you have used?
Which product do you try to resample, can you give me the name?
Are you working on the command line or in the desktop application?
Last question, which operating OS are you using?
I could not update plugin installer, and it always remind me unconnected to updata center. I want to know how to resample sentinel2A data in a shapefile extent and in band 2,3,4,8. I appreciate for your reply.
Maybe you are behind a proxy server which causes problems or there is some other problem why you can not connect to our server. I once heard that the “Great Wall” caused problems. Maybe you should talk to your IT admins.
Have you followed this thread:
For the resampling, as long as you don’t have the latest modules it might be problematic to resample S2 data.
But in general you can do it.
Using a shapefile to crop the data to a certain area is not easy. In the GUI you can define a geographic bounding box and from the command line you can specify a polygon using WKT. But this will cut out also only the bounding box of the polygon (because images have to be rectangular). You can mask the data afterwards by using the land/sea mask processor.
You will find several examples in the forum how to do this.
I tried to resample a S2A image, and after that I tried to compute biophysical indices LAI and APAR and got errors. When, after resampling, I checked the meta data, all the bands shows native resolutions. Please see the screen shot. Why resample did not converted all the spatial resolution to 10 m , any idea? Please help. Thanks.
The image that I had downloaded is S2A_MSIL1C_20170526T172901_N0205_R055_T14TLL_20170526T173505
My main issue is I was not able to compute LAI and fAPAR and the error was the S2MSI bands have different spatial resolution. To make all the bands equal spatial resolution of 10 m I tried to re sample it, but it did not work. How should I overcome this problem and compute LAI?
I have exactly the problem, that the my “resampling/subsetting/export to Geotiff”-Graph is working if I run it via the Graph Builder in the SNAP 6.0 desktop application, but if I run the same Graph via commandline using gpt I get an error
Error: [NodeId: Write] Product writer is unable to write this product as ‘GeoTIFF-BigTIFF’: Cannot write multisize products. Consider resampling the product first.
I have tested your graph and it seems to be working properly here. Could you please execute the command “gpt --diag” to verify that the version is also the 6.0 when you execute gpt? Perhaps you have an old version of SNAP installed and your path is not updated.
