The solution – digital enroute charts
For the past two years, NGA and ESRI have worked on an ambitious program to overcome technology hurdles and create a completely GIS-based aeronautical charting process to produce the NGA standard aeronautical charting products. The foundation of the approach is the geodatabase. With the collaborative effort of NGA and ESRI teams, additional fields were identified to support digital chart production. The NGA aeronautical database was imported into an ESRI ArcSDE geodatabase and data was pre-formatted for chart during the data ingest. On a weekly basis, NGA provide database updates and these transaction are loaded into the geodatabase that has been optimized for cartographic output.
