In ArcMap, here is how you can calculate sequential numbers using Field Calculator. Set field calculate to python. Paste this in pre logic script: rec=0 def autoIncrement():  global rec  pStart = 1   pInterval = 1  if (rec == 0):    rec = pStart   else:    rec += pInterval   return rec Paste this in second box autoIncrement() Check out one of my other posts about how to Convert from Degrees Minutes Seconds to Decimal Degrees in Python here .

Here’s a little function to pull numbers out of a string. import re def calculate(value):   newVal = re.sub("[^0-9]", "", value)   if newVal == "":     return 0   elif newVal is None:     return 0   else:     return newVal calculate( !Size! ) Happy GISing! Lindsy Hales Bentley

Who here loves Model Builder? Well, if you haven't had a reason to use it before, let's chat about it's benefits.  Prior to my working at an engineering firm, I never had a reason to use it.  There wasn't anything that I did on a regular basis that called for it.  I took all of the classes, read all of the books, and I just didn't get why it was useful. Then, I was asked to convert utilities for a project.  Not just once, but on a weekly basis.  Start to finish, it took me two weeks to convert and clean up the utilities from CAD on that beastly project.  Two.  VERY. PAINFUL. Weeks.  *Bang head against desk here.* This meant the utilities were never up to date in the project map.  After two months of figuring out the kinks in the conversion process, I was challenged to create a model of this process.  It looked something like this: Yes I'm OCD, and everything has to line up pretty. My first model.  I had my doubts ...
