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.</SPAN><BR /><BR /><SPAN>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.</SPAN><BR /><BR /><SPAN>Thanks</SPAN><BR /><BR /><SPAN>Andrew</SPAN></BODY></HTML> Thu, 13 Jun 2013 09:38:01 GMT https://community.esri.com/t5/data-management-questions/exporting-non-rectangular-raster/m-p/234317#M13305 AndrewMcClune1 2013-06-13T09:38:01Z Re: Exporting non-rectangular raster https://community.esri.com/t5/data-management-questions/exporting-non-rectangular-raster/m-p/234318#M13306 <HTML><HEAD></HEAD><BODY><SPAN>it will always be rectangular surrounded by nodata values...symbolize nodata as white and it will give the illusion of being absent</SPAN></BODY></HTML> Thu, 13 Jun 2013 12:38:04 GMT https://community.esri.com/t5/data-management-questions/exporting-non-rectangular-raster/m-p/234318#M13306 DanPatterson_Retired 2013-06-13T12:38:04Z
