How to convert from GeoTIFF to PNG/JPG and Web Mercator in Java?

Question

I'd like to convert raster image from (geo)tiff to an png/jpg and afterwards if it is necessary ... I'd like to convert the coordinates with help of EPSG-Codes to the OSM/Google Projection(EPSG: 3857/ 900913). All this i'm doing with java programming. Anyone a good hint... like an java libary??

Thanks a lot.

Answer 1

GeoTools should be able to do all of that - either natively or through the GDAL bindings.

Answer 2

Could cs-map help? You would need to check it can do raster though. Here's a user guide (PDF)
