You can access any attribute in your index layer (ie. pits) using the dynamic text: <dyn type="page" property="thefieldname"/>. So, in your case, it would be: <dyn type="page" property="Shape_area"/> From the help (waaaaay down, in a tip): With the dyn type="page" you can create dynamic text with any attribute field of the Data Driven Pages index layer. For example, if you have an attribute on the index layer named POPULATION, you can create a dynamic text tag using this field, <dyn type="page" property="POPULATION"/> to dynamically display the POPULATION values for each page in the layout. edit: I see now that you want hectares. You'll have to calculate a new field in your index layer for that. ... View more

I think you just need quotes: exp = "str(!Segment_Code!).zfill(6)" arcpy.CalculateField_management(outCrash, exp, "PYTHON") ... View more

Have you looked into the Watershed tool? You'll need the DEM to create your flow direction surface, but I don't know of any other way to generate upstream polygons. ... View more

Sorry to say it, but I'd guess the parameters are not valid (either "input" or "output"), but you'd have to post the code for anyone to figure it out. ... View more

Untested, but I think it should work. You'll have to change your workspace environment to point at the individual feature class, also. ...continue indentation from previous part of script...     fccl = arcpy.ListFeatureClasses("*", "All")     for featureclass in fccl:         rows = arcpy.SearchCursor(featureclass)         for row in rows:              drillhole = row.Label ...

Ah, yeah. I'm not sure what it's trying to accomplish with "fname_calc = [str(fname)]". What I am sure about is this: the script produced by exporting from ModelBuilder is a lie. ... View more

ArcMap doesn't like spaces in the field names. While you're removing those, make sure there are no extra spaces at the beginning or end of your field names. It doesn't look there are any, but for future reference ArcMap also doesn't like funny characters in your field names (for example, '#'). Also, there is no such thing as latitude -97.039914. ...

You need to wrap field names in !'s when they are used in the field calculator expression. arcpy.CalculateField_management(eco_pa, "OCCUR", "!" + fname_calc + "!", "PYTHON") Tip: make your calculation in the ArcMap field calculator and look at the results to see the proper syntax. ... View more

It'll depend on how complicated the join is. Mine finished in about 5 seconds, but I was only joining about 10 features to another 10. ... View more

Try replacing the back slashes in the path to forward slashes. edit: I just tried it and it works. second edit: after seeing Phil's post below, I should note that I didn't use the fieldlist parameter in my test - you should use his advice. ... View more

Just FYI, you can calculate the x-centroid using the "PYTHON" parser (v9.2) in the Calculate Field tool (expression stolen from this help page😞 float(!SHAPE.CENTROID!.split()[0]) ... View more

1.) Convert polygon to line (Feature to Line - requires ArcInfo) 2.) Append or Merge together 3.) Convert back to polygon (Feature to Polygon - requires ArcInfo) ...probably other ways, too. ... View more
