So your problem is nothing is ever removed from your selected features? Can you post your data you are running this on? Or at least the printout of the results from one of the runs? I'd also try using meters instead of kilometers. Overall this seems like a very convoluted work flow, but I don't understand enough of your problem to comment on a way to improve it. ... View more

Something like this should work. import arcpy import os # Set Workspace env.workspace = r"Database Connections\GENERAL_DATA - PROD.sde" # List Feature Classes fcList = arcpy.ListFeatureClasses("MGISP.GISONEAST*") # Loop through each feature class for fc in fcList:     # move features from sde to gis01     arcpy.FeatureClassToFeatureClass_conversion(fc, os.path.join(output_folder, my_dir, my_gdb), fc[16:], "") You could also do something like this, depending on your situation. fc.lstrip("MGISP.GISONEAST") ...

Please read this thread. http://forums.arcgis.com/threads/48475-Please-read-How-to-post-Python-code Python uses elif. Also, here is a better way of seeing if nothing is selected. dsc = arcpy.Describe("LayerName") selection_set = dsc.FIDSet if len(selection_set) == 0: ... View more

I believe I found a reason to keep Python. Could someone confirm for me if the "Feature Class to Shapefile" tool in the toolbox under Conversion tools is a Python script?  The icon for this tool seems to resemble a script as opposed to the normal hammer icon.

Not sure if this is what you are looking for. I use DB managed groups instead of AD users, so you will need to find a way to tap into AD to get your list of users to grant the privileges to and loop through them. The win32api or active_directory modules should be able to get what you want. http://timgolden.me.uk/python/active_directory.html http://www.python.org/getit/windows/ import arcpy sde = r"sde_instance_path.sde" arcpy.env.workspace = sde fc_List = arcpy.ListFeatureClasses("some_filter") fc_List.sort() for fc in fc_List:     try:         print "Granting privileges to " + fc         arcpy.ChangePrivileges_management(fc, "# group/user to grant priv", "GRANT")     except:         print "Passing " + fc         pass ...

Here is a library for Python: http://pypi.python.org/pypi/mgrs#downloads Well there you go. Python really can do anything. Just remember to get the right version for your python install. (2.5 for ArcGIS 9.3) ... View more

I'm sure it is possible, just not sure how feasible. You could try starting here to get ideas. Java and Python have a strong enough relationship that it should be fairly easy to cross over. http://www.ibm.com/developerworks/java/library/j-coordconvert/ ... View more

It's a way to replace almost anything you would regularly do manually with an automated script or tool. Geoprocessing, data management, logging, export PDF maps etc are all useful way to leverage python in a GIS environment.

Sorry about that....Yes it is the outShp variable that the script doesn't recognize I would imagine you are looking for an actual shapefile (.shp) to create the feature layer from? Or did you create a feature class in a  geodatabase? I'd try something like this, probably not really needed depending on your needs, but you should be able to adapt to your purposes if the output type/extension is the issue you are indeed having. import arcpy outWorkspace = arcpy.GetParameterAsText(0) arcpy.env.workspace = outWorkspace arcpy.CheckOutExtension("3D") try:     fcs = arcpy.ListRasters()     for fc in fcs:         outRaster = "reclass_" + fc         #Reclassify's raster cells         arcpy.Slice_3d(fc, outRaster, 2, "EQUAL_INTERVAL")         outShp = fc.strip(".tif")         if outWorkspace.endswith(".gdb"):             output_type = "FGDB"             output = os.path.join(outWorkspace, "%s" % outShp)         elif outWorkspace.endswith(".mdb"):             output_type = "PGDB"             output = os.path.join(outWorkspace, "%s" % outShp)         else:             output_type = "SHP"             output = os.path.join(outWorkspace, "%s.shp" % outShp)         #converts raster to polygon shapefile         arcpy.RasterToPolygon_conversion(outRaster, output, "SIMPLIFY", "VALUE" )         outLyr = outShp + "_lyr"         #make layer from shapefile so I can select by attribute         arcpy.MakeFeatureLayer_management(outShp, outLyr)         arcpy.SelectLayerByAttribute_management(outLyr, "NEW_SELECTION", ' "GRIDCODE" = 1 ') ...

Works fine for me. Not sure why you need the semicolon at the end of your lines. This isn't Java. What version of Python and win32 are you using? Also, you do this from win32con import MB_OK, MB_YESNO But call it like this anyways? win32con.MB_YESNO Wait, are you trying to execute this as a script tool through ArcMap? I don't think that will work. Why not just have a checkbox in the tool window asking if it is downloaded? Or better yet, ask them to navigate to it using a file dialogue, or search for it in the script itself. ... View more

Those don't look like proper unicode quotation marks. `1` should be '1' etc Not sure how that issue would just appear over night though. Or why they are there in the first place. May just be a hold over from the older version of python. I don't get a syntax error with it but it just doesn't look right with those characters. ... View more
