In Brief Texas Department of Transportation
(TXDOT) tasked Geo-Air Consulting with a planning study for expanding two runways at the San Marcos Airport.
Controlled Compatibility Land Use reclassification of existing land use/parcel data.
Obstruction penetration analysis performed on imaginary surfaces as defined by Federal Aviation Administration (FAA).
Solution length for runway 17-35 and 13-31.

Controlled Compatibility Land Use
Analyzed CAPCOG Land Use and Parcel Shapefiles.
Validated accuracy of data with a cross check of COSM land use and parcel data.
Created “Controlled” area Buffered runway centerline
Clipped CAPCOG Land Use Shapefile and TXDOT aerial image.
Reclassified Land Use types Grouped values

Polygon Construction Created polygon shapefiles from TXDOT
shapefiles. Edited vertices to correct dimensions.
This procedure provided all needed imaginary surfaces for analysis.
Completed polygons moved into proper spatial location by measurement.
