Vector data is a representation of the world using points, lines, and polygons. This data is created by digitizing the base data, and it stores information in x, y coordinates. Vector data is one of two primary types of spatial data in geographic information systems (GIS) – the other ...

load the shapefiles into PostGIS with the bash loader script (open and modify it first if necessary). This will add the data from every single shapefile in every single map sheet into one country-wide layer per feature type. Run the SQL script. It does a few bulk data cleanups, such ...
1. A method of viewing map data in a computer-implemented geographic information system, comprising the steps of: retrieving a map window file from a data storage device coupled to a computer, the map window file containing map definition information that identifies vector-based map data used ...
1. A method of obtaining a map in a computer graphics program comprising: receiving a request for a map picture; obtaining a map file in response to the request; determining, from the map file, a uniform resource locator (URL) that identifies a storage location of vector based map data, ...
