The tags documented in the GeoTIFF specification are unrelated to the raster data descriptions in the TIFF specification. I am using Matlab 7 (R14) service pack 1. If I use ArcGIS this would be easy to do. geotiffread function in Matlab. MATLAB Central contributions by merialu. If some one have matlab code for data conversion (. I am new to mapping toolbox and here the thing I need help: I have a large geotiff file and I like to extract a small area of it (still in a geotiff format) based on a shape file I have access to (I tried 'maptrims' but it requires the 'RasterInterpretation' field of the 'spatial referencing object' to be 'cells' which in my case it is 'postings'). I can't seem to get the same thing done with GeoTiff image and no tutorials handle that. I would like to know how I can visualize and extract the lat-lon information from my geotiff file. This MATLAB function reads a georeferenced grayscale, RGB, or multispectral image or data grid from the GeoTIFF file specified by filename into A and creates a spatial referencing object, R.
