I just wanted to point out that just using if not row.Stand may yield undesired results (remember, explicit is better than implicit from the Zen of Python). Take the following example: >>> for i, sample in enumerate(['a',1,None, '', ' ', 0]): if not sample: print 'value "{}" at index {} is empty'.format(sample, i) value "None" at ...

Yes. Data Driven Pages were introduced at ArcGIS Desktop 10.0: Data Driven Pages allow you to quickly and easily create a series of layout pages from a single map document. A feature layer, or index layer, divides the map into sections based on each index feature in the layer and generates one page per index feature. arcpy.mapping was also ...

Yes, the location central meridian will change the pattern of distortions in most map projections. In the polyconic projection the length of the central meridian is correct, and also along latitude lines (which are not straight). The latitude of origin doesn't affect the pattern of distortions, but only sets the Y (Northing) = 0 location. For China, if your ...

The documentation for Near Analysis indicates "NEAR_DISTANCE: The distance between the input and near feature. The value is in the linear unit of the input features coordinate system, or Meters when the Method parameter is set to GEODESIC and the input is in a geographic coordinate system." So my understanding of that statement is: A Geographic Coordinate ...

Here are a few resources I've found about automatically generating maps for transit and other data: Stott et al. "Automatic Metro Map Layout Using Multicriteria Optimization" - Abstract: "This paper describes an automatic mechanism for drawing metro maps. We apply multicriteria optimization to find effective placement of stations with a good line ...

I think it is important to make this Q&A cover not just ArcGIS Desktop 10.0, Python 2.7 and Python 3.1, but also to incorporate the latest versions of desktop products from the ArcGIS platform and the Python programming language. For Python support in the (currently) latest desktop products from the ArcGIS platform I think you should consider: ArcGIS ...
