The package includes data bases of the coastlines, lakes, major rivers, minor rivers, and international boundaries of the entire world at resolutions suitable for world or regional maps. Provincial boundaries for most of the world as well as U.S. county boundaries are also included. The package also includes image data bases that can be uses to produce relief maps or color backgrounds. Image data bases are raster images or “picture maps."

Geo3D X

Geo3D X, based on Quesa (3D graphics library), Geo3D is a standalone 3D Metafile (3DMF) viewer with navigation (and some editing and animation) features. It lets you navigate through space rather than being limited to manipulating models. Geo3D includes editing tools for shaders, styles, lights, etc. Geo3D understands URLs that are attached to 3D objects in a model. It's available with viewpoints, picture (sequence) export, animation, dynamic coordinate planes and axes, as well as many other features. Geo3D is partly scriptable and recordable using AppleScript. Geo3D supports plug-in renderers.

GeoTagger

Drag your images to the GeoTagger icon and it will get the current location from Google Earth (version 4 or higher) and insert it into the Exif data of the images.

GISLook and GISMeta

GISLook and GISMeta are plug-ins for Mac OS X 10.5 that show GIS data in the Finder. Supported formats are: ESRI Shape, E00, ArcInfo Coverage, USGS DEM, SRTM, ESRI ASCII grid, ESRI Binary grid, BIL, BIP, BSQ, Surfer Grid, PGM.

GMT

GMT is a free, public-domain collection of 60 UNIX tools that allow users to manipulate (x,y) and (x,y,z) data sets (including filtering, trend fitting, gridding, projecting, etc.) and produce Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots through contour maps to artificially illuminated surfaces and 3-D perspective views in black and white, gray tone, hachure patterns, and 24-bit color. GMT supports 25 common map projections plus linear, log, and power scaling, and comes with support data such as coastlines, rivers, and political boundaries. GMT works with Mac OS X.

Google Maps Plugin

Google Maps Plugin are plug-ins for the Mac OS X Address Book app.

GPS and Go!

GPS and Go! lets you expand your digital hub to include global positioning system (GPS) devices. Experience the wealth of information that GPS devices are able to provide to your Macintosh by linking data with physical locations.

GPSNavX

GPSNavX is a solution for the boater that wants to take the Mac aboard for the real-time display of the position on full color charts. You can plug your GPS into your Mac OS X system and watch as your boat moves along in real-time, plotting a track behind the boat and logging your historic position on a digital chart. And GPSNavX doesn't require a GPS to work with charts.

GPS PhotoLinker

With GPS PhotoLinker the latitude and longitude from your GPS receiver can be directly embedded into the metadata of your digital photos, creating a permanent record of where the photo was taken. GPSPhotoLinker saves the position data in the EXIF header, a common format used by many programs, like iView Media Pro which can immediately read the position data and use that information for sorting photos. GPSPhotoLinker reads gpx files for track data, a common xml format for saving tracks, waypoints and routes from a gps.

GPSUtility

GPSUtility is software for displaying GPS data including speed, bearing, position and satellite information

Hipparchus

Hipparchus is named after the ancient Greek astronomer and originator of the concept of latitude/longitude, Hipparchus, which runs under Mac OS X, uses a spatial indexing method and modern vector algebra to provide speed, precision and flexibility to aid developers with an open approach for location information. It offers modeling and manipulation of zero, one and two dimensional objects, allowing for ellipsoidal modeling of points, lines and regions. Functions are included for: conversion from all popular coordinate systems; dynamically adjustable indexing; proximity, union and intersection; mapping and display; debugging. What's more, the library includes a third-order orbital modeler to aid in the management of satellite data.
