Title: An Analysis of Airport Database Features and Their attributes Using GIS and Remote Sensing. Section 3: Features 21-31
This investigation analyzed sixty airport database features, from 21 through 31 and their attributes using GIS and Remote Sensing. This entailed the evaluation of the compliance of each airport based on requirements specified by the RTCA’s DO-272, User Requirements for Aerodrome Mapping in order to make airport surface operations safer. Also implemented was the use of Remote Sensing to visually extract the features from a TM image. Verification is to be done in accordance with the process of developing and implementing an electronic aircraft direction system that can handle greater traffic volume, is unaffected by poor visibility conditions, and will facilitate the sharing of information among air traffic, airline, and airport communities. Maintaining aerodromes in updated, standardized Airport Mapping Databases (AMDB), will allow the development of a Surface Management System (SMS), tower display and cockpit moving maps for this purpose. Completion of the task required the acquisition of the DO-272, for the requirements, as well as the database from ftp://naco.faa.gov/SF21. The attributes for each individual feature is verified using the text, noting that each polygon has different attributes, their numbers ranging from seven to seventeen. Using ArcView, each feature’s attribute table was displayed. Next, manipulation of the default parameters for a TM image of the BWI sub-site launched in ENVI, yielded an accurate image from which to visually extract features. Overall, of the sixty airports verified, 54% of the required features have zero compliance. Of the 45% that have any compliance, those features only comply with about 51% of the attributes. Research suggests that there is much revision to be done to the AMDB’s if developing technologies are to be accurate.
