exiftran is a command line utility to transform digital image jpeg images.
It can do lossless rotations like jpegtran, but unlike jpegtran it cares
about the EXIF data: It can rotate images automatically by checking the exif
orientation tag, it updates the exif informaton if needed (image dimension,
orientation), it also rotates the exif thumbnail.
It can process multiple images at once.
GeoAPI provides a set of interfaces from OpenGIS specifications.The development
community in building GIS solutions is sustaining an enormous level of effort.
The GeoAPI project aims to reduce duplication and increase interoperability by
providing neutral, interface-only APIs derived from OGC/ISO Standards.
An R interface to the 'dygraphs' JavaScript charting library (a
copy of which is included in the package). Provides rich facilities
for charting time-series data in R, including highly configurable
series- and axis-display and interactive features like zoom/pan and
series/point highlighting.
GEOS (Geometry Engine - Open Source) is a C++ port of the
Java Topology Suite (JTS). As such, it aims to contain the complete
functionality of JTS in C++. This includes all the OpenGIS "Simple
Features for SQL" spatial predicate functions and spatial operators,
as well as specific JTS topology functions such as IsValid().
GimpLensfun is a Gimp plugin to correct lens distortion using the lensfun
library and database.
The plugin can be found under "Filters > Enhance > GimpLensfun".
It automatically detects camera, lens type, and corresponding parameters
from the EXIF information embedded in the image file.
GOCR/JOCR is an OCR (Optical Character Recognition) program, developed
under the GNU Public License.
GOCR can be used with different front-ends, which makes it very
easy to port to different OSes and architectures. It can open many
different image formats, and its quality have been improving in a
daily basis.
OpenGL-based 3D visualisation tool for source control repositories.
The repository is displayed as a tree where the root of the
repository is the centre, directories are branches and files
are leaves. Contributors to the source code appear and disappear
as they contribute to specific files and directories.

The Grid Analysis and Display System (GrADS) is an interactive
desktop tool that is used for easy access, manipulation, and
visualization of earth science data. The format of the data may be
either binary, GRIB, NetCDF, or HDF-SDS (Scientific Data Sets).
GrADS has been implemented worldwide on a variety of commonly used
operating systems and is freely distributed over the Internet.
gtkam is an universal, free GTK+ application that will allow
downloading, saving, and manipulation of images from several
different digital camera models, or from the local harddrive.
gtkam supports a wide array of digital camera models.
