Is it possible to use the coordinate system from a data frame in the current map document within an update cursor?
I have data in GCS WGS84 and I want to update area/perimeter/length fields across a geodatabase with UTM WGS84 units. I want to acquire a coordinate system for the cursor from the current map data frame coordinate system, not a reference feature class. A piece of my current script is below, which would return useless area/length values from GCS coordinates:
for fc in fcList:
fc = fc +"\\"
fieldList = arcpy.ListFields(fc, 'lengthSize')#lengthSize field
fieldCount = len(fieldList)
if (fieldCount > 0):
print "perimeterSize field present in: " + fc
arcpy.AddMessage ("perimeterSize field present in: " + fc)
with arcpy.da.UpdateCursor (fc, ['SHAPE@LENGTH', 'lengthSize']) as cursor:
for row in cursor:
row = row
print "Updating 'lengthSize' field in: " + fc
arcpy.AddMessage ("Updating 'lengthSize' field in: " + fc)
print "No lengthSize field in: ", fc
arcpy.AddMessage ("No lengthSize field in: " + fc)
Is this possible, or does a "describe" (like that found here: http://pro.arcgis.com/en/pro-app/arcpy/get-started/setting-a-cursor-s-spatial-reference.htm) have to be used?
