Try going to the folder location of the jpg file, and delete all of the files with the same name, but different extentions (ie: if your file is terrain.jpg, delete terrain.aux.xml and terrain.ovr and terrain.jgw etc.) then when you add it back in to the map for georeferencing, it should behave as expected.

The correct syntax for the NULL keyword is: "Z" IS NULL do not use the "=" with NULL. Regards, Jim ... View more

David, I like to create functions, and then use them inside of models. You could do this and let the model take care of the iterations by setting the input for ou2 as a parameter, and setting its properties to "A list of values". Set an input parameter for ou1, drop the home range polygons of interest into the "ou2" parameter, and execute. It is efficient and flexible. I have a simple script to set the symbology of a raster dataset from a layer file, and use it this way often. Image of model attached. Regards, Jim ... View more

Hello, Emma. What you want to do is set a "Page Definition Query" on your starting point dataset. This is not available for the layer that the data driven pages (DDD) are based on, but this does not sound like an issue for you. Once you have your DDD defined, on your starting point layer: >>Layer Properties>>Definition Query there will be a new tab at the bottom called Page Definition. Use this to limit the display of your starting points. If I am unclear, search "Using Page Definition Queries" in the help. Regards, Jim ... View more

Rory, I had success running your code (see below), so your simplification for posting eliminated your error source. Regards, Jim [HTML]import arcpy mxd = arcpy.mapping.MapDocument("F:\TestMap\TestMap.mxd") df = arcpy.mapping.ListDataFrames(mxd, "")[0] for lyr in arcpy.mapping.ListLayers(mxd):     if lyr.name == "TstResults":         print "found it"         arcpy.SelectLayerByAttribute_management(lyr)         print "selected"         lyr_extent = lyr.getSelectedExtent() print df.extent print lyr_extent newExtent = df.extent newExtent.XMin = lyr_extent.XMin newExtent.YMin = lyr_extent.YMin newExtent.XMax = lyr_extent.XMax newExtent.YMax = lyr_extent.YMax print newExtent df.extent = newExtent mxd.save() del mxd, lyr print "finished"[/HTML] ...

how about import_file = raw_input("Enter file for input:  ") ... View more

Habboub, There must be some variables that impact the movement over time, and those need to be assigned weighting factors for use in the prediction of future locations. You need to understand why 1984 to 1986 2 year period is comparatively large vs 1992 to 1999 7 year period. Any prediction based on the xy locations versus time without consideration of other variables may as well be random. Try adding some more information for better responses. Regards, Jim ... View more

I did a bit of research and ended up using PyScripter. It will do autocomplete and I have been happy with it. The recommendation came from ESRI dev teams in the forums. Regards, Jim ... View more

Jon, I had success with your code in the active window Note: 2 raster layers returned, and values 0 and 89 are correct: [HTML]>>> import arcpy >>> mxd = arcpy.mapping.MapDocument("CURRENT") >>> df = mxd.activeDataFrame >>> rasLayers = arcpy.mapping.ListLayers(mxd,'Chromium*', df) >>> for lyr in rasLayers: ...     x='570715' ...     y='133340' ...     place = '%s %s' % (x,y) ...     cellvalue = arcpy.management.GetCellValue(lyr, place) ...     print cellvalue ...     0 89 [/HTML] ...

Steve, I was tinkering with your label expression and could not get it to work until I modified it: "%s %s %s"  % ("<CLR red='36' green='93' blue='206'>", [WELLNM], "</CLR>") Regards, Jim ... View more

Could you be clearer? When you say you wish to exclude points, do you mean you do not want them to display, or do you want to perform some action on the subset of the data? Regards, Jim ... View more

PK, You create a variable called "ExtractedNLCDFileName" for your output raster, then as an argument for your out_raster you use "ExtractedNLCDFile". Regards, Jim ... View more
