I have some tiff files (2 for example) and a shapefile. The real format of the tiff files is geoTiff.
I want to get the points inside the shape boundary. Each point should have 4 parameters: geom(coordinates), red, green, infrared (we have tiff files with such info).
At the end of the operation I want to get a vectorized shape with points.
Could you please give me some advice on how can I do that programmatically. Are there any libs/tools? It is all in the context of geoserver/postgresql/geomajas framework.
Upd: now I have more information. My tiffs will be one of the Landsat combination: http://gif.berkeley.edu/documents/Landsat%20Band%20Information.pdf
The main question now is: to get RGB channels info in exact point, should I parse image points on RGB,or I can get this info from geoTiffMetadata (there is http://download.deegree.org/deegree3/nightly/core/javadoc/org/deegree/coverage/raster/io/imageio/GeoTiffIIOMetadataAdapter.html ). I didn`t find really useful info while debugging the code and calling the methods of GeoTiffIIOMetadataAdapter.
