I'm updating somebody else's old Python scripts, and trying to make sure I understand their logic and desired outputs while streamlining the code. In this particular script, it specifies an output projection in the processing environment settings.
import arcpy Output_CS = "GEOGCS['GCS_WGS_1984',DATUM['D_WGS_1984',...(etc, etc, etc)" arcpy.env.outputCoordinateSystem = Output_CS
I think this means that all the subsequent geoprocessing operations (e.g.,
arcpy.Buffer_analysis) output in WGS84 without needing an additional
If that is the case, is there any accuracy risk to running a buffer analysis directly to a geographic coordinate system? In other words, does it do the projecting after the buffer's been appropriately sized?
(The original input data is in a projected coordinate system, one of the NAD83 state plane systems.)
