Disclaimer: RoadMap is known to have bugs. The data provided by the US Census Bureau is known to have errors. The RoadMap maps generated from the US Census Bureau data contain even more errors. Use RoadMap at your own risk.
Caution: always look at the road when driving a car, do not look at the RoadMap screen. The proper way for using RoadMap in a car is to have a passenger use RoadMap, not the driver.
Caution: the maps available on this pages are little endian, i.e. they will work fine on a PC, Zaurus or Linux/iPAQ. These maps will not work on PowerPC (i.e. MAC) or Sparc computers. Maps for these architectures might become available in the future. In the mean time users of these architectures will need to build the maps themselves. Stay tuned!
Caution: the maps for the non-US portion have been built from the Digital Charts of the World (DCW). The official horizontal accuracy of the DCW is 2040 meters: the resulting maps are therefore unusable for car navigation in their current state.
Caution: these maps require RoadMap version 1.0.8 and later. They are not compatible with earlier versions of RoadMap.
The data used for the US states and territories comes from the Census Bureau, an agency of the U.S. Government, and is in the public domain. Therefore, the RoadMap maps of the US states and territories are in the public domain.
The data used for the non-US portion was extracted from the Digital Charts of the World (DCW), a product from the US Department of Defense. Most of the DCW data is public domain, but some is copyrighted by ESRI (administrative boundaries). The data included in the RoadMap files only include roads information and thus is all in the public domain.
We suggest using
Thank you for your understanding.
The following file is the RoadMap directory of counties. It is used to select which county or counties matche a specific geoposition or a specific address. This file must be present in the map directory or RoadMap will not work.
The following files are gzipped tar files that contain the RoadMap map files, one tar file per state. (To install the map files: go to the final map directory and extract the map files using the "tar xzf DOWNLOADED-FILE" command.)
New in RoadMap 1.0.8 is a preliminary support for the Digital Charts of the World. This is a first draft: only roads are shown, maps are organized in large world blocks (not by country), etc..
It should be noted that the Digital Charts of the World contain limited information and cannot be the base for street navigation: only major roads are included, and sometime very few of them.
