cogserver

Expose any GDAL recognized raster file as a HTTP accessible on-the-fly COG (Cloud Optimized GeoTIFF)

The on-the-fly COG file is not materialized to disk, can be of arbitrary size with little RAM consumption and can be accessed in a piecewise way with HTTP GET Range header.

Quality: proof-of-concept

What remains to be implemented:

• expose metadata in GDAL_METADATA tag
• allow compression
• expose overviews when they exist
