Author: Tim Johnson 900 6th Street Phone: 515-382-7245 Story County, Iowa, updates its land use plan every five years. The creation of critical resource areas for the land use plan integrates soil productivity, flood frequency, slope, and vegetation, to name a few variables. This process took weeks gridding a 576-square-mile county in 1993. In 1999 GIS allowed similar modeling to be done in a matter of hours. Each process will be summarized to show how even simple GIS modeling can increase productivity. |
