topic Issue in FRAGSTATS 4.1 moving windows with ArcRaster files in Data Management Questions https://community.esri.com/t5/data-management-questions/issue-in-fragstats-4-1-moving-windows-with/m-p/160120#M8938 <HTML><HEAD></HEAD><BODY><SPAN>Greetings. I've been working with the moving window algorithm in Fragstats 4.1, for a landscape ecology study in the Chilean Metropolitan Region. For this purpose, I'm running 10 moving windows varying from 5x5 to 255x255 pixels in a 4682x4715 disturbance binary raster with 30m pixel resolution to measure contagion and composition.</SPAN><BR /><BR /><SPAN>The problem arises when I'm trying to do the process with window sizes over the 1000m. I find quite disturbing that the process takes less than 5 minutes to complete (contrary to window sizes under 1000m, where it takes up to 20 minutes to complete), but the progess bar freezes at the "100%" at the end of the bar.</SPAN><BR /><BR /><SPAN>I tried to split the raster in small sub-landscapes, and to use only one parameter at the time, in order to reduce the memory usage (I thought that would be the problem) but the problem persists.</SPAN><BR /><BR /><SPAN>According to the pre-run of the model, I have 4194303k of available memory, the landscape size and window size, uses 86306k and 197k each.</SPAN><BR /><BR /><SPAN>Any thoughts, help, or advices will be highly appreciated.</SPAN><BR /><BR /><SPAN>Thanks.</SPAN></BODY></HTML> Wed, 02 Oct 2013 04:37:52 GMT RodrigoVillegas 2013-10-02T04:37:52Z Issue in FRAGSTATS 4.1 moving windows with ArcRaster files https://community.esri.com/t5/data-management-questions/issue-in-fragstats-4-1-moving-windows-with/m-p/160120#M8938 <HTML><HEAD></HEAD><BODY><SPAN>Greetings.
