Airports are a focus of many spatial projects, both large and small. And if you have a copy of ArcGIS with the free datasets loaded on to your hard drive, then you might have found that this data is less than ideal in many cases. So if you are working in the United States and need more detailed airport information, check this additional free dataset offered by Esri.
This USA airport file is delivered as a layer package that can be opened with a double-click. Layer packages save symbology, layer order, etc. making them an easy way to send a map file to fellow ArcGIS users. Once you open the file, you will see detailed airport boundaries, runway vectors and robust metadata.
Until my next edition of the Free For All, happy hunting for free geospatial goodies!
