The results are stored in a feature class. One of the things I'm trying to determine about the rasters is if pyramids have been made for each of them. The only way I can find so far is to look for a .rrd file with the raster. But that won't work for any rasters that are stored in a geodatabase. Can someone please tell me if there is some other way in Python to detect if pyramids have been created?</P></BODY></HTML> Mon, 11 Aug 2014 23:01:09 GMT https://community.esri.com/t5/python-questions/can-i-detect-if-pyramids-have-been-created-for-a/m-p/663693#M51562 AllanMills 2014-08-11T23:01:09Z Re: Can I detect if pyramids have been created for a raster in Arcpy? https://community.esri.com/t5/python-questions/can-i-detect-if-pyramids-have-been-created-for-a/m-p/663694#M51563 <HTML><HEAD></HEAD><BODY><P>Apparently <A href="http://resources.arcgis.com/en/help/main/10.2/index.html#//009t0000001p000000">you can't</A> unless you can program in a right-click (can't find anything anywhere, except *.ovr files can also be created, but I don't know if you can check for them)</P></BODY></HTML> Tue, 12 Aug 2014 00:18:28 GMT https://community.esri.com/t5/python-questions/can-i-detect-if-pyramids-have-been-created-for-a/m-p/663694#M51563 DanPatterson_Retired 2014-08-12T00:18:28Z Re: Can I detect if pyramids have been created for a raster in Arcpy? https://community.esri.com/t5/python-questions/can-i-detect-if-pyramids-have-been-created-for-a/m-p/663695#M51564 <HTML><HEAD></HEAD><BODY><P>I am not aware of any way to do this using arcpy but would also be interested to know if this functionality exists.</P><P></P><P>The functionality *should* be part of <A href="http://resources.arcgis.com/en/help/main/10.1/index.html#/Describe/018v00000066000000/">arcpy describe</A> but it doesn't seem to be exposed.
