tweets Posted April 19, 2012 Report Share Posted April 19, 2012 I'm looking for a way to extract the extents of a raster dataset using Arc9.3.1 or FME 2012. I need to export them into a polygon feature class. i'm not talking about the north south east west of the entire dataset either, I am talking the actual data extents of the dataset, this will be an irregular polygon that follows the edges of the data. I know that a raster catalog has a wireframe at certain zoom levels but this is not what I want and I don't want to convert all my datasets to raster catalogs. Right now we are editing manually,and it is a pain. I've tried the Raster Extents coercer in FME but no luck (I think is has to do with the desktop I'm using but...)

rahmansunbeam Posted April 19, 2012 Report Share Posted April 19, 2012 The first thing that came to my head is this, -create a really big polygon/vector to hold the raster in AG/Erdas, -now clip it with the raster, -convert it to line. You'll get the inner boundary, delete the other. Such an expert I am, aren't I. :cool: Quote Link to comment Share on other sites More sharing options...
tweets Posted April 19, 2012 Author Report Share Posted April 19, 2012 I figured it out with FME. 1. RasterResampler using nearest neighbour with a low percentage. 2. RasterCellCoercer to extract the polygon extents for each cell. 3. Dissolve the polygons using the Technology Preview option 4. Write to a feature class FME is awesome Quote Link to comment Share on other sites More sharing options...
