However, on the section in Chapter 2 on accessing raster data, when I run agent analyst it only reports the "no data" value. It doesn't seem able to access the actual raster data values, in this case I am using an enhanced vegetation index (EVI) raster. The code I am using is exactly as appears in the book, apart from appropriate changes for my file and path names. I know my application is accessing the correct raster, as when I changed the "no data" value, the new value is reported.</P><P></P><P>If I run the actual agent analyst application that comes with the book it works correctly. The only differences between that application and the one I've written is the&nbsp; coordinate systems are different (both are projected coordinate systems: mine is WGS_1984_World_Mercator, with geographic coordinates system GCS WGS 1984; the book application projection is NAD_1983_HARN_UTM_Zone_12N with geographic coordinates system GCS_North_American_1983_HARN). Also the book application's raster simply has values of 0 or 1 indicating whether food is present or not.</P><P></P><P>Any advice would be appreciated</P><P></P><P>GE.</P></BODY></HTML> Sat, 03 Jan 2015 16:12:17 GMT GrahamElliott 2015-01-03T16:12:17Z Agent analyst doesnt cannot access raster data https://community.esri.com/t5/spatial-data-science-questions/agent-analyst-doesnt-cannot-access-raster-data/m-p/478757#M1074 <HTML><HEAD></HEAD><BODY><P>I'm working through the Agent Analyst exercises in the book by Kevin Johnston.
