This layer represents footprints of public airports and select heliports in DVRPC's 28-County Data Service Area. The features in this layer were generated by digitizing all discernable runways, taxiways, aircraft parking areas, tarmac, and aircraft hangers using the best available aerial imagery.<\/SPAN><\/P>

Attribute fields titled \"RASP\" and \"RASP_Type\" were included to indicate whether an airport is part of DVRPC's Regional Airport System Plan (RASP). The RASP currently contains 24 airports: 3 commercial, 10 reliever, and 11 general aviation or recreational facilities. In addition, the current RASP identifies three operating public use heliports and one military airbase. The \"DVRPC_REG\" field indicates whether a facility is within the DVRPC 9-county region. The \"FP_UPDATED\" field indicates the year of aerial imagery that was used to update the facility's footprint.<\/SPAN><\/P>

Additional attribute data pertaining to these facilities may be sourced from the Federal Aviation Administration (FAA). The FAA provides airport data for the entire United States via various downloadable tables: <\/SPAN>http://www.faa.gov/airports/airport_safety/airportdata_5010/<\/SPAN><\/A><\/P>
