VMAP0 Vector Map (VMap) Level 0 is an updated and improved version of the National Imagery and Mapping Agency's (NIMA) Digital Chart of the World (DCW®). The VMap Level 0 database provides worldwide coverage of vector-based geospatial data which can be viewed at 1:1,000,000 scale, i.e. 1cm=10km. It consists of geographic, attribute, and textual data stored on CD-ROM or as downloaded files.
The GEOnet Names Server (GNS) provides access to the National Geospatial-Intelligence Agency's (NGA) and the U.S. Board on Geographic Names' (US BGN) database of foreign geographic feature names. The database is the official repository of foreign place-name decisions approved by the US BGN. Approximately 20,000 of the database's features are updated monthly. Geographic Area of Coverage: Worldwide excluding the United States and Antarctica.
Geonames provides free geo-data such as geographical names and postal codes. The database contains over 6 million entries for geographical names whereof 2.2 million cities and villages (more statistics …). The data is accessible free of charge through a number of webservices and a daily database export. The geonames webservices offer free geocoding based on geographical names or postal codes.
Geonames is integrating geographical data such as names, altitude, population and others from various sources. Users may manually edit, correct and add new names using a user friendly wiki interface.
This web site will allow you to download the boundaries and layers of different countries, in Arc/INFO export format, from ESRI's Digital Chart of the World data set. Our mapping function will give you a preview of the data. The entire data set is also available, on CD-ROM, at the Pennsylvania State University's Maps Library or from ESRI.

Chameleon is a distributed, highly configurable, environment for developing Web Mapping applications. It is built on MapServer as the core mapping engine and works with all MapServer supported data formats through a regular MAP file. Probably there are several problems installing Chameleon on Debian Sarge, see http://agrogeomatic.educagri.fr/debian/.
