comment Average frequency of zip code change for a given address over the course of year
@Maksim Understood. Can you tell us anything else about the dataset? For example, do the individual features for ZIP codes ever overlap? And how are point addresses (e.g. P.O. boxes) represented? Mostly I'm just curious about how well ZCTAs are a proxy for the official thing. Thanks for weighing in!

@Maksim Is this Zip Code feature class you speak of publicly available? Or is it an internal USPS only product? The only polygonal ZIP code dataset I was aware of was ZCTAs from the Census Bureau.

comment Distance from rivers, taking into account terrain elevation
Are you trying to determine the flow distance to the nearest river based on flow direction? Or the straight-line distance that accounts for slope?

comment Unexpected Polygon Zoom Extents with a Rotated Dataframe
@amasephy Glad that it worked out for you. ArcMap's dataframe rotation functionality is implemented in a klugey way that isn't well supported by ArcPy.

comment Unexpected Polygon Zoom Extents with a Rotated Dataframe
@amasephy Are your grids always the same aspect ratio? I'm assuming you are created a printable map book, so should the maps always be 8.5" by 11" or something like that?

comment ArcGIS 10.1 Remove (or SetNull) areas of overlapping rasters
@Markus Glad to hear it. I don't know why the issue wasn't solved by changing raster calculator's extent, but at least this workaround fixed the issue.

@Markus It looks like the processing is being limited to the extent of the roads_raster layer. Try rasterizing your roads again with the "Extent" environment variable set to the suitability layer (along with the correct snap raster and cell size) so it's the full extent.

@Markus Can you post a screenshot? I'm having trouble visualizing what you mean by "some of the corners have been cut off in a perfect line."

@Markus Two ideas. First, try setting the "Extent" environment variable of Raster Calculator to be the suitability layer. Second, try making sure that all of your layers are in the same projected coordinate system.
