[gdal-dev] GDAL Warp API : Transforms on Z

2016-02-01 Thread Adam Stambler
Hi All, I am trying to implement a warp from a latitude, longitude, altitude (LLA) image into a custom coordinate system using the GDAL Warp API. The transform between LLA and my coordinate requires scaling and shifting the elevation. My coordinate system is a local tangent plane on the Earth's

Hi Florent, yes, I am aware of that and I managed to create BufferedImages from GDAL Datasets. However, I find the Java Image API (and the whole subject) relatively complex, so I am not sure if my code is efficient. Can anybody have a quick look at my code and tell me if there are any quick perfo

Hi, in fact with the Java binding there's no method to get a BufferedImage from a Dataset. You can warp your image and get a Dataset You have to create a (Java)Raster and fill it with the raster or a part of the raster of the warped Dataset. But be carefull because when you create a Raster you m

Hi again, I would like to try using the Warp API from Java. It seems that there are currently no Java bindings available. - Did anbody work on Java bindings for the Warp API? - How hard would it be to define them? I may be able to invest some time here. Best regards, Markus -- Markus Schneider

kss, thanks. gdal.ReprojectImage(..) looks like what I will be using then. :-) My use case: - My huge (ECW) dataset is in EPSG:28992 - I want to extract a defined region in EPSG:4326 as a (Java) BufferedImage How can I get hold of a suitable destination dataset so I can use ReprojectImage(...)?

I'm trying to do some aerial photo processing specifically converting RAW imagery to DOQs. Right now I have working code that uses GDAL to read/write the rasters and uses my own code to do the actual image processing. I would like to use the Warp API so I can take advantage of the ChunkAndWarpIm
