Python and GIS - Beyond ModelBuilder and PythonWin
This is a presentation I gave last February at the ESRI Petroleum User Group conference in Houston, TX. I just discovered SlideShare the other day.

Some new maps: 8-Digit HUC Watersheds of Arkansas, Night Lights of Arkansas, and other assorted watershed maps
I finally found the time to finish some maps I had been working on for quite some time. Watersheds of Arkansas is one I had started back in 2003, and just never got a chance to finish. I’m very pleased with how it turned out though. The detail in the elevation is amazing. Took me a while to get the colors/contrast/transparency just right on that. Night Lights of Arkansas is one I threw together pretty quickly using an already existing template. I ran across the data one day on the web and thought it would make a nice map. Here’s the Night Lights metadata if anyone is really interested.
Both of these maps (as with pretty much all of my maps) were made using ArcGIS 8.3 from ESRI.
Processing lots of rasters
I had a post a few days ago about data, and how it made my happy, and how that was kinda pathetic. And that got me to thinking - What’s the largest raster I’ve processed?…..Hhhmmmm. Well, here it is:
I needed to make shaded relief maps for our site at work, like the one seen here. In order to do this, I needed a DEM that covered a very large area. Read more »
DRGs for Oklahoma
It’s kinda sad when you get excited over data. But this isn’t just data, it’s data that will make my life a little bit easier. My boss bought me the 7.5-minute DRGs (Digital Raster Graphics) for the entire State of Oklahoma on CD from Charttiff. I already have the Arkansas set, and having them has been a real timesaver. When you rip them off of the CD and onto your hard drive, you select the projection you want and the format (JPEG, TIF). It’s pretty slick. And most importantly, this means that I don’t have to hunt around for them on the web, find them in four different formats and in three different projections, and then convert them and reproject them. Yeah, this will make my life alot easier.
