Impact of GDAL JPEG 2000 lossy compression to a digital elevation model
Original language description
Mobile platforms bring possibilities to use distributed services in several users' environments. One of the conditions of the mobile platform is to transfer as less as possible amount of data via network. When dealing with geodata in mobile environment it is always necessary to use compression algorithms to lower their size. Digital elevation models in a GRID form are usually compressed with LZW or DCT technique, but the best compression ratio is now available with wavelet algorithms. The compression can be loss or loss less. The paper describes results of tests of JPEG 2000 loss compression technique. We studied impact of JPEG 2000 loss compression on quality of DEM. We have tested several options of OpenJPEG library to find how these options can change resulting compressed DEM. The main part of the research was focused on pre-filtering of DEM before compression. We have find out a way how to minimise average error of loss compression when keeping the same compression ratio. (C) Sprin
