Mapping and Spatial Analysis to Expand Rural Broadband Access

High-speed broadband internet access is a critically important issue for many aspects of daily life, yet populations in rural areas are often unserved or underserved with reliable internet connectivity. Expanding broadband internet coverage in rural areas may have significant economic potential, especially since it enables precision farming which in turn increases yields, particularly for row crops such as corn and soybeans. This paper introduces methods that utilize GIS spatial analysis and remote sensing to assist in efforts to expand rural broadband access using case study counties in Illinois. Specifically, the methods presented here: (1) quantify current cropland production as well as future potential production in currently unserved or underserved rural areas; and (2) automate mapping of vertical assets from Light Detection and Ranging (LiDAR) data that may be utilized as high points to expand broadband coverage. Collectively, these methodologies may be used for policy advocacy and to inform the decision-making process as future broadband expansion initiatives are considered in rural areas.
