What is GIS?

In a nutshell, GIS is drawing points (fire hydrants, road signs), lines (roads, rivers), and polygons (property lines, buildings) in a geographic environment.  Valuable data is then attached to those drawings (owner name, address, valuations, etc).  Then, drawings, or layers, are pulled together to form a map.  Finally, you can ask important questions of the map.  For example, “how many houses are in the Indian Creek flood zone and what is the total assessed valuation of those houses?”  If this technology intrigues you, learn more about the field of GIS at this link.

What does Pottawattamie County GIS do?

Our primary function is to maintain the property lines for all properties owned in the county.  We assign a parcel number to each property.  Along with property lines there are hosts of other layers of data we maintain: lots, subdivisions, dimensions, roads, jurisdictions, environmental features, etc…  To see the list of layers we maintain click here.

It is not enough to simply draw the features.  They have to be delivered to you the user in a logical, easy-to-use application with tools that utilize the value of the geographic data.  These applications are available here.

History of the Department

The Pottawattamie County Geographic Information Systems (GIS) Department was formed in June of 2002 to administer and grow the County’s GIS program. In 1998, the County made a significant investment in GIS technologies; including aerial photography, various spatial datasets, powerful new workstations, and leading GIS software. By 2002, the County recognized the potential of their GIS and subsequently addressed the need for internal management and budgeting. The decision was made to form an independent County department, whose administrator would report directly to the Board of Supervisors. Capital and budgeted monies were set aside to fund the new department. In June of 2002, a GIS Program Manager was hired and the GIS Department was officially formed. Today the department is headed by the County CIO and staffed by two full-time employees (occasionally an intern) and serves the following County departments with GIS data and services:

  • Auditor: property mapping and elections
  • Communications/911: mapping, addresses, software support
  • Conservation: mapping, software support, projects, specialized data, GPS
  • EMA: software support, specialized data, emergency action plans, exercises
  • Engineering: mapping, specialized data
  • Planning: software support, specialized data, projects, GPS
  • Sheriff: custom maps, crime mapping

The department also provides support to the cities in the county, non-profits, the chambers of commerce, planning organizations, school districts, and private businesses.
