GADM database of Global Administrative Areas

GADM is a spatial database of the location of the world's administrative areas (or adminstrative boundaries) for use in GIS and similar software. Administrative areas in this database are countries and lower level subdivisions such as provinces, departments, bibhag, bundeslander, daerah istimewa, fivondronana, krong, landsvæðun, opština, sous-préfectures, counties, and thana. GADM describes where these administrative areas are (the "spatial features"), and for each area it provides some attributes, such as the name and variant names.

The data are available as shapefile, ESRI geodatabase, RData, and Google Earth kmz format. Shapefiles can be used for most mapping and "GIS" software. You can download a free program such as Q-GIS or DIVA-GIS. The RData files can be used in R with the 'sp' package loaded.

You can download the data by country or for the whole world.

Obtaining shapefiles from OSM data

This is where you can find extracts of maps from different places around the world. From here you can download:

OSM XML extracts by country
Garmin Map Files (OSM.err edition)
Osmosis country bounding polygon
Shapefile extracts by country
Navit maps by country
GPX POI by country
TomTom POI by country
OSM XML feature extracts by country
Adobe Illustrator files by country

The files provided on these pages are created from OpenStreetMap map data. Because OpenStreetMap is a work in progress many of the countries are only partially mapped or are incomplete. The data contained on these pages has not been checked or verified and we don't recommend using it for any mission critical applications.

Bundled Software

Sometimes it's just easier to go one place. Here are some places worth going.

FWTools http://fwtools.maptools.org/

Frank Warmerdam maintains most of the open source infrastructure for handling projections and file formats. It's handy to know what and where they are, since they are often prerequisites for installing other packages: proj4 and GDAL (pronounced "goodle", rhymes with noodle).

FWTools includes pre-compiled binaries for both Windows and Linux of GDAL and proj4, along with the web map server MapServer and raster-oriented desktop OpenEV. Frank contributes to or maintains all these packages.

GIS Knoppix http://www.sourcepole.com/sources/software/gis-knoppix/

GIS Knoppix is a self-booting Linux CD set up to be a sort of Linux workstation on a CD. It has office productivity tools, like OpenOffice , along with a full set of GIS tools: desktop, web map server, etc.

MapServer for Windows (MS4W) http://www.maptools.org/ms4w/index.phtml

MS4W installs pre-compiled windows binaries that comprise a complete development environment for making applications with the MapServer web map server.

Enterprise GIS: Spatially Enabled Databases

PostGIS http://postgis.refractions.net/

PostGIS is the most commonly used back-end database in free software. Most of the desktops listed are PostGIS clients, as well as the MapServer and GeoServer web map servers.

MySQL http://www.mysql.com/

MySQL has spatial extensions , and is supported in both the MapServer and GeoServer web map servers.

Desktops

GRASS http://grass.ibiblio.org/index.html

GRASS , the Geographic Resources Analysis Support System, is a long-standing, complete GIS system. It was originally written in Unix, and runs best in Linux or Unix of some kind. Although the interfaces have recently improved it still has a learning curve. The GRASS community is enormous, and world-wide, with commensurate support resources.

JUMP http://www.jump-project.org/

JUMP supposedly works everywhere, but is much more windows oriented. Has a nice graphical user interface (GUI), and includes conflation tools. It requires SUN's Java Virtual Machine (JVM).

OpenEV http://openev.sourceforge.net/

OpenEV is a raster-oriented viewer with some editing capability. Can display vectors, and create simple shapefiles. Most vector capabilities (snapping, etc.) are not present.

Quantum GIS (QGIS) http://qgis.org/

QGIS is mostly a viewer, with some fairly new editing capabilities. It is more mature on the Linux side of the house, but does have a windows preview release. It is extremely simple to operate, and creates configuration files for the MapServer web map server.

Thuban http://thuban.intevation.org/

Thuban is a viewer, and is definitely cross-platform (Windows, Linux, etc.). It's based on Python.

UDig http://udig.refractions.net/

UDig is still in development, but may suit your needs even in its current form. It's designed to expand on JUMP functionality, and conform to important Open Geospatial Consortium standards. Refractions Research is planning to sell support for uDig.

Web Map Servers

There are quite a variety of these. The two listed below have the most developed capabilities.

MapServer http://mapserver.gis.umn.edu/

MapServer has a very simple set-up and is economical with system resources. It is widely supported and integrated with other packages. The MapServer community has an annual conference.

GeoServer http://geoserver.sourceforge.net/html/index.php

GeoServer is Java-based, and has a fairly complex set-up. It is widely supported, and integrated with other packages.

ArcGIS for Smartphones and Tablets

Map Navigation, Data Collection/Reporting, and GIS Analysis from Your iOS, Windows Phone, or Android Device

ArcGIS apps for smartphones extend the reach of your GIS to a wider audience. These are free applications that you can download from the Apple® App Store , Windows® Marketplace, or Android™ Market. All three apps include a developer-focused SDK that you can leverage to build your own custom applications.

• Find and share maps from ArcGIS Online.
• Use tools to search, identify, measure, and query.
• Collect and update GIS features and attributes.
• Perform GIS analysis by accessing geoprocessing tasks
