I created a loop to zoom to every shape in a shapefile and export that particular extent. The only problem is that the jpeg is given the number of the row as name. I want to give it the name of a field in de dbf. Does anybody have an idea how to do that? This is done the same way you accessed the shape field: import arcpy from arcpy import env from arcpy import mapping mxd = arcpy.mapping.MapDocument(r"C:\gisbestanden\pythontest\test13.mxd") df = arcpy.mapping.ListDataFrames(mxd)[0] fc = r"Z:\kaarten\COROP\coropmultipart.shp"  count = str(arcpy.GetCount_management(fc)) x = 0 while x < int(count) + 1:     rows = arcpy.SearchCursor(fc, "fid = " + str(x))     for row in rows:         xmin = row.shape.extent.XMin         ymin = row.shape.extent.YMin         xmax = row.shape.extent.XMax         ymax = row.shape.extent.YMax         # get the field contents to name the file         filename = row.getValue("NAMEFIELD") # or: row.NAMEFIELD         df = arcpy.mapping.ListDataFrames(mxd)[0]         newExtent = df.extent         newExtent.XMin, newExtent.YMin = xmin, ymin         newExtent.XMax, newExtent.YMax = xmax, ymax         df.extent = newExtent         # use the field contents in the filename         mapping.ExportToJPEG(mxd,              r"C:\gisbestanden\pythontest\gemeentekaart\JPEG_{0}.jpg".format(filename))         print "successfully printed JPG"     x += 1 ...

Is it possible to use the inline model variable substitution when the input is a list of variables?  I know that there are other methods of inline variable subing, such as the %i% option, but in this case the name is essential because I will be using this later in the model to perform a table join with each County's massive soils table.  Any thoughts? If you use the Iterate Multivalue tool (or any other iterator), the iterator generates variables on each loop, just for this purpose. If what you are getting isn't exactly what you need, you can use the Calculate Value tool on each loop to manipulate these values to create the output pathname you want. use the output of the Calculate Value tool in percents embedded in your output file name, for example "Soil_%shapename%.dbf". Be sure and use preconditions to make sure the variable gets calculated by Calculate Value before you run the tool that uses its name for an output. ... View more

Is this a custom tool (.NET) or a script tool? If it's a script tool, documentation is added by right clicking the tool, selecting Item Description and editing the metadata. For GP tools built using .NET (called a "custom geoprocessing tool" instead of the more common "script tool" built in Python or another scripting language) you do indeed need to create a .chm file and set the tools HelpFile property to point to it. Although the Microsoft Windows HTML Help SDK is still supported (in Windows 7), it's very difficult to use. This is usually handled using third-party help authoring applications (Esri uses one obviously) that create documentation in various formats (including .chm) from a single source. Robohelp is one of the most popular ones out there. ... View more

The button that is usually at the bottom of a geoprocessing tool for changing environments is not there when I drag the tool on to the model builder canvas and open it from there. Inside the model, right click the tool, click properties, pick the Environments tab. If you want to use other model elements to set environments, say, extent, you can use the connect tool to click and drag from the element to the tool and follow the dialog (environments/extent for example). Here's the help article with more details about how environments work inside Model Builder: Arc 10.0 Help: A quick tour of managing model environments ... View more

Due to poor python skills i don't have the possibility to write scripts to automate my raster operations. As a solution to my problems I thought the batch mode of raster calculator would do the trick. I use Microsoft Excel to generate commands and pathways for the output files, resulting in long lists. But much to my dismay I can't find any way to enter them all at the same time in the batch window. I have been forced to copy every single line by it self, and paste in to each corresponding batch row. I guess there must be a way to paste them in a more efficient way, but I can't find out how. If somebody could suggest me a solution I would be forever grateful! In Arc 10.x, you should be able to paste your raster calculator expressions into the python command window, as long as you enter this line first: from arcpy.sa import * ... View more
