Over the weekend, v1.7.0 of the popular GDAL/OGR library was released. Although technically not a geo-web product, GDAL/OGR is used by a number of popular geo-web tools such as UMN MapServer. We also used a tool from the beta of this version in our recent Polar Maps and Projections article.
as well as the usual bug fixes and minor changes, GDAL/OGR 1.7 adds support for a number of less-common raster formats ( BAG, EPSILON,
Northwood/VerticalMapper, R, Rasterlite, SAGA GIS Binary, SRP
(USRP/ASRP), EarthWatch .TIL, WKT Raster ); support for a number of vector formats (DXF, GeoRSS, GTM, PCIDSK, VFK); significant improvements to existing raster & vector drivers ( GeoRaster, GeoTIFF, HFA, JPEG2000 JasPer, JPEG2000 Kakadu, NITF, CSV, KML, SQLite/SpataiLite, VRT); support for Python 3; and the new gdaldem and gdalbuildvrt utilities.
