Automating COGO with Python ?

MiguelGarriga1 — Tue, 11 Oct 2011 19:54:39 GMT

Is there a way to automate entering COGO descriptions using Python ? For example, for COGO descriptions that are several pages long. Is it possible to automate the data entry by parsing these long COGO statements and combining them with Python scripts ? Either a Python script that accepts a text file as input, or a hardcoded Python script with the pre-parsed COGO descriptions embedded into it. Just wondering what techniques / best practices are out there.

Has this question been answered anywhere else?

I have a similar need. I have hundreds of scanned descriptions that I have managed to apply some text recognition to in order to extract the bearings and distances into an excel table. This process is still a bit cumbersome, and by no means refined.

My problem now is that I would like to be able to import my Line/ Curve Tables (bearings, distances, and curve geometry) directly into ArcGIS, eliminating the need to manually type the information into either the COGO traverse tool or Parcel Fabric Traverse tool. I have been unable to figure out if this is possible.

If anybody has any advise, it would be greatly appreciated.

You can definitely parse your string to make simple geometries like point/line/polygon using arcpy geometries, however I don't believe it's possible to create true curves - you're stuck with straight line segments.

If straight segments are acceptable and you're having issues parsing your COGO statement/creating geometries, please provide an example of a line/curve table row (I'm not familiar).
