Exporting maps without borders

GrantHumphries1 — Mon, 07 Nov 2011 21:33:45 GMT

Hi,

Does anyone know how to export JUST a raster as a GeoTIFF? For example, when I use the "Export Map" function, the raster is exported as a GeoTIFF just fine, but there is a large white border around it, and for me to get the raster by itself (with no white border), I have to import it to photoshop and clip to the map.

Does anyone know how to do this? (or what I'm talking about??)

Cheers
G

Set your page size and map size to be the same. Pick the same ratio and a suitable size so that the number of dpi is easy to calculate. Set the percentage margin to zero. Leave on the grid for tests to check that you have got it right. I found it very difficult to get it to the exact pixel size.

Unfortunately you cannot export the world file and projection if you are using layout view, only data frame view. If you need those, then use a grid with known dimensions so you can calculate the world file yourself and then use geotiffe.exe to populate the TIFF files afterwards. You may also be able to use PIL python module to do this.

Thanks very much for that!

That seems really silly that there isn't an option to simply export the area within the extent you're interested in. There should be a function "Export map within Clip"
