New Digital Chart Format from FAA

FAA AeroNav Products is transitioning to a new method of producing its digital charts. Details are available here.

UPDATE (1/30/14): Based on productive feedback from our chart users, we have further improved the rendering of our raster chart samples. Type and features appear clear and crisp with improved edge definition. Compressed file sizes are generally unaffected, while uncompressed file sizes are much smaller.

VFR Charting has greatly improved its digital-Visual Chart (d-VC) process and we are excited to give our users an opportunity to see the new product before full implementation. Instead of using scanned chart images, the new d-VC is created directly from our digital files, resulting in a crisper and brighter image with improved georeferencing.

The new files are of the same type and format as the old files. Each .zip file contains a TIF, geospatial (.tfw), and metadata (.htm) file. However, Sectional Charts will no longer be divided into a north and south half. The entire chart will be contained within the TIF. Additionally, the resolution of the TIF is improved to 300 dpi.

We are allowing our users to view and test the new product. However, we will continue to supply the existing d-VC files through the 6 MAR 2014 chart cycle. Please see the Sample Sectional (ZIP) file provided.

Your feedback is very much appreciated. Please send any comments, questions, or concerns to 9-AMC-Aerochart@faa.gov.
