A JavaScript-based parser for the GeoTIFF image format. This parser is based on the GPHemsley/tiff-js : canvas part has been removed, but GeoTiff geoKey has been added. Not all Tiff capacity has been coded.
What's supported for the Tiff part
Compression : None and Packbits
Strips / Tiles : Supported
Photometric Interpretation : RGB , GreyScale, BiLevel, RGB, RGB Color Palette
Planar Configuration : PLANARCONFIG_CONTIG
Size : images should not be to big in order to be loaded properly.
What's supported for the GeoTiff part
ModelPixelScale : Supported
ModelTransformation : Supported
ModelTiepoint : GTIFTiepointTranslate is not implemented
Some part of the code is a port from LibGeoTiff 1.4.0
See http://trac.osgeo.org/geotiff for geoTiff information
Why GeotiffParser.js ?
My attempt is to parse GeoTiff files coming from a WCS server (I'm using a Geoserver) in order to do some computation like obtaining the elevation along a path. With GeoTiff client side you could also change dynamically the rendering function.
