Radian International vector digital data http://www.edwards.af.mil 1998RTNEAR_Area.txt The shapefile RTNEAR contains 2 NM route boundary buffer polygons. The route boundaries were constructed from route description points and route width information contained in DOD Flight Information Publication AP/1B: Area Planning Military Training Routes North and South America, 3 December 1998. Route center lines are included for the following IFR/VFR routes: IR-234, IR-235, IR-236, VR-1205, VR-1206, VR-1214, VR-1215, VR-1217, VR-1218, VR21293 The shapefile was created as a basemap layer for display of the route 2NM buffer of route boundaries. According to EAFB specification, the polygons in this shapefile define the surface area that is near IFR/VFR routes. The latitude and longitude coordinates and other route attribute information were key entered from AP/1B into a Microsoft Access database. Latitudeand Longitude were then converted to decimal degree format and exported to Arc/Info UNGENERATE format. The GENERATE command was used in Arc/Info to create the route description point coverage, which was subsequently converted to EAFB format projection. The remaining attributes from the Access database were then converted to Info format and joined to the RTPOINT coverage PAT. en 1998 publication date Complete As needed -118.760385 -114.343119 40.198769 34.204460 route ifr/vfr buffer airspace MEAR63 California Kern County 1998 Microsoft Windows 2000 Version 5.1 (Build 2600) Service Pack 1; ESRI ArcCatalog 8.3.0.800 This dataset is property of EAFB.
