Notes

Image: All fires since 1970 using semi-transparent polygons.

Process:
NIFC polygon/point vector data is retrieved daily for current year and as needed for previous years. Daily Bash script downloads data using wget and database is updated using ogr2ogr. The layer is then served by Apache/MapServer WMS as defined by the firefreq.map file.
