GIS Tools—An IPMP Service

Service request form

IPMP members can also get help with using IPMP data sets through free GIS Tools.

GIS Section Tool

IPMP users can accurately define sections of the road that have been analyzed with the GIS section tool. The GIS section tool, developed by CTRE, defines, modifies, and maintains pavement management section locations and limits, eliminating the hard copies presently used to show roadways requiring section description.

Here is how the GIS section tool works:

1. Local agencies describe section locations and limits
2. CTRE staff interprets this information and converts it to geographic coordinate pairs

The GIS Section Tool resolves data integration challenges such as inconsistent road names or incomplete section data.

Cost

The GIS Section Tool is available free of charge to agencies enrolled in the Iowa Pavement Management Program.

GIS Software

The GIS software used by the IPMP is also available to IPMP members free of charge.

• ArcExplorer by ESRI is a free GIS data viewer. This software offers an easy way to perform basic GIS functions. ArcExplorer is used for a variety of display, query, and data retrieval applications and supports a wide variety of standard data sources, such as IPMP data sets.
• ArcView, also by ESRI, makes it easy to create maps with your own data or records from existing databases.
• GeoMedia Viewer by Intergraph, another free GIS software, provides a basic desktop viewer of geospatial data, using files across networks or on CDs.

Cost

ArcExplorer and GeoMedia Viewer are available free of charge.
