About Me

I've been in and around GIS since the early 1990's.  For much of that time, I've been working with utilities and 9-1-1, focusing on diverse areas such as work managment systems, GIS data management, and address management tools.  But, as you'll see below, that is hardly all of it.  I've designed systems for FEMA, supported legal proceedings, built support tools for natural resource analysis, and studied natural disasters as well.  I've lived here in Colorado with my wife for over 20 years now.  And, like a lot of people who live here, I get out and enjoy the outdoors by hiking, fishing, golfing, and just hanging around.  But, if you're here reading this, you are probably more interested in what I've been doing for a living:


Work Experience

What follows here is a summary of what I think is most relevant to the work I am doing now as Jerry Steenson GIS.  I won't go into all of my previous work history, at least not here.  Ask me sometime, and I'll fill you in on the rest.


Jerry Steenson GIS
July 2011 – Present

As the name implies, I am currently working for my own corporation, named (not so imaginatively) after myself.  I've taken this opportunity to move back into the utilities sector.  I'm working with major utilities on their work management systems, focusing on environmental issues related to vegetation management and construction work management, code migration (VBScript to Python), and database synchronization tools.  This work has been all client/server web-based applications, which has given me the opportunity to expand my skills with technologies such as Silverlight, ArcGIS server, and Azteca Cityworks.  On another note, for a different client, I developed an application for converting custom spreadsheet data into working GIS data used to analyze bird habitats.


Contact One
November 2001 – June 2011 (9 years 8 months)

I was the first outside employee, and then one of two owners of Contact One. While there, I was the primary architect and author of a variety of software products for use in Geographic Information Systems (GIS) for public safety and 9-1-1. When Intrado of Longmont, Colorado acquired Contact One in June of 2011 as a major addition to its GIS operation, I decided to move out on my own, and offer my services and products through Jerry Steenson GIS.

Among the products I managed at Contact One were:

MapSAG was the leading tool for GIS data management in 9-1-1. The first such tool to be developed in ESRI’s ArcObjects, MapSAG has been used in a wide variety of locales, including Los Angeles County, California and Harris County, Texas, two of the largest such jurisdictions in the nation. The State of Vermont has also implemented MapSAG. In addition, many smaller entities across the country use this product as their primary data management tool. I created the architecture and designed this product, and did the majority of the programming, with the help, along the way, of some very talented individuals.

SimpleCell is a GIS toolkit used to manage cell tower data for 9-1-1. Again, I designed this product, and did much of the programming.

QuickPoint is a legacy dispatch mapping product I designed and wrote during my time at Contact One. It is still in use in many PSAPs, and still being implemented. I was practically the sole programmer for this product.


Along the way at Contact One, I also had extensive customer interaction, helping with technical sales, RFP responses, GIS process design, and a multitude of custom applications and extensions.  I've successfully done all aspects of creating and managing complex technological solutions.


Miner & Miner
February 2000 – November 2001 (1 year 10 months)
I was a project manager for Miner & Miner, which is now part of Schneider.  I worked with various private and public utilities in implementation of Miner & Miner’s software products and custom services delivery.  That was right at the time that Miner & Miner was transitioning ArcFM from an AML-based platform to .net, making it a challenging and fascinating time to be there.


Berger & Company
August 1998 – February 2000 (1 year 7 months)
I was a GIS consultant at Berger (now Modis), primarily working in programming tasks for ArcInfo, using Arc Macro Language (AML) The largest single project I undertook was for Colorado Springs Utilities, where I designed and developed a set of tools for address data validation and management (similar in some respects to MapSAG), and a complex set of map book production code.


Colorado State University
January 1991 – August 1998 (7 years 8 months) Fort Collins, Colorado

I worked in various positions at the University, all as Research Assistant. First, I was on contract to design, prototype, and guide development of the indirect economic loss module for HAZUS. I invented the methodology and algorithms for this module, which is loosely based on economic Input/Output technology (with a nod to French Physiocrats). The next position I held was as the lead GIS analyst and programmer for the Center for Ecological Management of Military Lands. In this job, I built various custom processes to help with ecological analysis, and built a complex suite of hard-copy paper map generation tools that replicated Defense Mapping Agency maps for military bases. My final position was working for Ingrid Burke in the Department of Forestry, mostly doing GIS modelling of regional effects of global climate change with some of the top climate modelers of the day.



Here are just a few of the technologies with which I have acquired proficiencies during my career:

  • C# (C-Sharp, not C-Pound)
  • Visual Basic (6 and .net flavors)
  • Structured Query Language (SQL)
  • VBScript
  • JavaScript
  • Python
  • HTML
  • Silverlight
  • ArcObjects
  • MapObjects
  • Arc Macro Language (AML)
  • Visual Studio
  • Team Foundation Server
  • Subversion
  • Oracle
  • SQL Server

Well, this gives you a feel.  Primarily, my strengths lie in the use of various of ESRI's development products, and the supporting programming languages on which those solutions utilizing those products are developed.  But (and most experience developers will tell you this), languages tend to blur together after a while.  Sure, they all have the peculiarities, quirks, and 'best practices', but they all pretty much end up doing the same things.  We'd all rather not have to jump around too much.  It's kind of a waste of time, but that's just the way it is in this line of work.



B.A. The Evergreen State College, Olympia, WA
M.A. (Economics) Colorado State University, Fort Collins, CO
M.S. (Forestry) Colorado State University, Fort Collins, CO

Note:  Forestry is where the Remote Sensing/GIS program lived at CSU back when I was there.

Implementing a Virtual MSAG

The NENA NG911 standards, while not complete, are largely finished.  In the realm of data management, one of the biggest departures from the past that is introduced is a far greater role for GIS (more...)
