Geographic information system (GIS) data is a foundational component in the migration to, and continuing operation of, Next Generation 911 (NG911) systems.
But developing local GIS data so that it aligns with NG911 standards is a laborious and time-consuming process that can take months or years to complete.Despite this, MCP’s Robert Horne, one of the firm’s GIS gurus, cautions in a recent whitepaper against taking shortcuts in developing GIS data for use in a NG911 environment. Spe cifically, Robert writes that public safety agencies should avoid using the U.S. Census Bureau’s open-source Topologically Integrated Geographic Encoding and Referencing (TIGER) data for 911 call-routing purposes. TIGER data is available free of charge, but does not meet basic public safety requirements, nor the established NG911 standards, Robert writes. This is due to incomplete data attribution, poor spatial accuracy, incomplete coverage of the PSAP’s jurisdictional footprint, inaccurate street names and address ranges, and a lagging data update schedule. local GIS data so that it aligns with NG911 standards is a laborious and time-c onsuming process that can take months or years to complete.
