STL StreetData database is a national product, with consistent standard mapping attribution (road names, road types, road hierarchy, and suburb/town names) across Nigeria. The data is available for some 120 cities across Nigeria including the national highway.
It is intended that updates to the database will be released annually. The latest release of STL StreetData (Version 8) was in March 2009.
STL StreetData is a database, not a software application, so GIS or mapping software is required to view or manipulate the map content. The StreetData database is built to comply with open, international standards, therefore the database can be readily loaded into a range of specialist applications.
STL StreetData can be provided, ready for use, in either ESRI (.SHP) or MapInfo (.TAB) formats, and is compatible with many other mapping systems capable of importing ESRI or MapInfo data. The map can overlay with our other high quality Digital Map products to provide a powerful interactive functionality, and is built to support integration with GPS applications.
- ESRI Shapefiles (.SHP) or interchange format (.E00)
- MapInfo Tables (.TAB) or interchange format (.MID/.MIF)
