An Examination of Geospatial Data Availability and Data Accessibility by State

From the GSDI Legal-Econ Listserv:

Article: An Examination of Geospatial Data Availability and Data Accessibility by State
Documents to the People 39(1): 27-31?(Spring 2011)

This article focuses on a relationship between geospatial data availability and data accessibility, based on a hypothesis that state and local governments would contribute to the Geodata.gov clearinghouse (representing data availability) if states have open GIS record access laws. The analysis involved three steps: (1) collect data from Geodata.gov to measure geospatial data availability by state; (2) collect laws and opinions of attorneys general of all states to measure accessibility to geospatial data; and (3) correlate the data to test the hypothesis that state and local governments would contribute data to Geodata.gov clearinghouse if state laws encouraged open access to the GIS records. Result: “The results were not exactly what I was hoping to get. The hypothesis was rejected in all models but one.”
