Summary | 1 Summary Leveraging NextGen Spatial Data to Benefit Airports NextGen began in December 2003 with the Vision 100 Century of Aviation Reauthorization Act. Its goals were âto take advantage of data from emerging ground-based and space-based communications, navigation, and surveillance technologies; and to integrate data streams from multiple agencies and sources to enable situational awareness and seamless global operations for all appropriate users of the system.â Airports play a critical role in achieving these goals. This guidebook, along with the accompanying four volumes, is intended to help airports fulfill this important role and maximize the benefits they receive in return. This volume focuses on one key aspect of airportsâ role in NextGen: the creation, maintenance, and use of spatial data that is critical to many NextGen programs. Spatial data can come in a variety of formats, and at various levels of accuracy, completeness, and currency. Over the past few decades, many airports have implemented one such format, geographic information systems (GIS), to meet a spectrum of needs. In recent years, the FAA has developed ad- ditional requirements for airports to collect geospatial data sufficient for meeting myriad needs such as instrument approach procedure design, construction as-built surveys, navigational aids (NAVAIDs) installation/relocation, master plans and airport layout plans (ALPs), and airfield configuration changes. As the FAA moves toward employing more advanced solutions for airspace and airfield safety, opera- tional efficiency, and situational awareness under NextGen, the need is increasing for high quality, current, and accurate spatial data depicting airports, as well as the airspace around airports. The nexus of these spatial data requirements is the focus of this guidebook. Research Goals and Objectives This guidebook is part of a larger NextGen ACRP research project series that provides general informa- tion about NextGen while also detailing specific subject areas under NextGen. Other projects in this series include: ⢠ACRP Project 01-27, NextGenâA Primer; ⢠ACRP Project 01-28, NextGenâGuidance for Engaging Airport Stakeholders; ⢠ACRP Project 03-33, NextGenâAirport Planning and Development; and ⢠ACRP Project 03-34, NextGenâUnderstanding the Airportâs Role in Performance-Based Navigation.

2 | LEVERAGING NEXTGEN SPATIAL DATA TO BENEFIT AIRPORTS The main project objectives for ACRP Project 09-12 are to document the benefits that can be derived from spatial data collected in support of the FAAâs NextGen effort, how NextGen programs use this data, and how airports can maximize the use of this data. Although NextGen affects the entire national airspace system (NAS), not all programs within NextGen have a need for spatial data, produce spatial data, or have a direct benefit to airports. The focus of this research examined and elaborated on how spatial data produced by an airport is utilized within certain NextGen programs and, conversely, how spatial data that a NextGen program might produce could benefit an airport. Summary of Research Conclusions ⢠Some NextGen initiatives clearly benefit from spatial data or produce spatial data. Four priority areas are multiple runway operations (MRO), performance-based navigation (PBN), surface opera- tions, and data communications. ⢠MRO, PBN, and surface operations all have a need for and/or produce spatial data. ⢠Many airports have found it difficult to understand what is required of them to support the imple- mentation of NextGen, and there is a need to expand public outreach and education about these programs and data requirements. ⢠A challenge encountered by many users of spatial data is that there have been many sources that are sometimes redundant, not broadly accessible, and of varying degrees of quality. A duplication of data resides in the FAA databases, and additional duplication occurs as data is separately devel- oped by airports, by other public-sector agencies, and through third-party sources. ⢠The FAAâs Airports GIS (AGIS) program has long been called an âenablerâ of NextGen. AGIS has provided high-quality data required for the development of PBN and other flight procedures, but many programs within NextGen do not currently utilize AGIS data to its full extent. Although flight procedures and airspace analysis clearly take advantage of AGIS-compliant data where it exists, many NextGen capabilities rely on spatial data produced by third-party vendors. ⢠One goal of AGIS is for all airports listed in the National Plan of Integrated Airport Systems (NPIAS) to have spatial data populated in the AGIS databases. As the inclusion of additional airports contin- ues, and as more airports populate AGIS, additional NextGen initiatives will be able to take advan- tage of this data. ⢠Some reasons airports have not submitted data to AGIS include: (1) they do not perceive that the benefits exceed the cost of doing so; (2) the local FAA Airports District Office (ADO) is not enforc- ing or, in some cases, strongly encouraging it; and (3) many airports lack the resources needed to maintain this data over time. ⢠Many airports perceive that they bear new costs for the collection of spatial data but do not reap new rewards. Airports are, in fact, gaining new capacity, reducing minimums, and increasing safety because they have collected this data. Unfortunately, the benefits have not been as apparent as the costs, an issue which the FAA, RTCA, the ACRP Project 01-28 research team, and others are trying to address.

Summary | 3 Recommendations and Suggested Research ⢠An in-depth study of the spatial data needs for unmanned aerial systems (UAS) planning and op- erations, as well as ways in which GIS can support UAS, is suggested. ⢠An independent review of RTCA DO-272, User Requirements for Aerodrome Mapping Information and FAA Advisory Circular (AC) 150/5300-18, General Guidance and Specifications for Submission of Aeronautical Surveys to NGS: Field Data Collection and Geographic Information System (GIS) Standards, as well as an assessment of the potential for merging these two standards into one industry standard, also is suggested. ⢠The benefits and requirements of NextGen and AGIS are not fully understood by the aviation com- munity. A clear need exists for additional education of the aviation community about these benefits and requirements. Methods for further educating the aviation community and development of additional content to support these efforts are both needed.
