Not sure if it is something I am doing but I don't seem to be able to call the Con statement that you stated using the Con Tool. I am only able to call the attributes in the Input Conditional Raster. Are you suggesting to use the Con tool or should I use something else for this? Regards, Andrew

Both rasters are logical datasets so the three values I am trying to extract are where both rasters = 1, where the first raster = 1 whilst the other raster = 0, then the reverse of this (so when the second raster = 1 but the first raster = 0). Ideally I want a raster that shows all the data. The rasters have the same extent but do not overlap perfectly so currently I have only been able to produce a raster the shape of the first raster, whilst some of the pixels of the second raster are deleted as they are not contained in the first raster. Thanks

I am trying to join two rasters together that have different values so that they are a single dataset with the different values. I have tried using the Mosaic to New Raster tool but this seems to either miss some areas or merge the attributes. Ideally what I want to display is where the two rasters are the same, then parts which are not as 3 different attributes but not removing any of the original data. I have tried using the Equal to but this removes some of the data that I want to display. I have attached an example of the sort of thing I am trying to produce but this is with 3 different layers. How can I combine all this information and keep the separate attributes and all the data? The blue represents where the two rasters are equal, then the red and the green are where the two rasters are different. Regards, Andrew

Is there a way to export a raster but keep the original shape of the raster instead of export the image extent as well? I am extracting buildings from orthoimagery using building footprints. Some of the footprints are diagonally orientated so when I export the raster, for example to a .tif file, I obtained a rectangular footprint instead of the shape of the building footprint. I am then using this for further processing in MATLAB but the extra data and no data values around the image are causing data issues in MATLAB. I have tried other data formats but getting the same results. I have also tried to use the Selected Graphics (Clipping) option in the Export Raster Data menu, but this option is greyed out on my option. I am unclear if this means use selected shapefiles to extract the data or features have to be selected in the Raster dataset to be extracted. Thanks Andrew
