Geo-Information (GI) systems and data are essential elements of any successful application of LBS technology. GI systems perform the primary function of providing real-world context to LBS applications (by translating positional data into information that can be understood by a user). GI data includes streets, addresses, maps, routes etc and, often, application-specific information such as current traffic and weather conditions, points of interest, business listings etc.
GI data must be accurate and current. The process of collecting and collating GI data for commercial purposes is extremely complex. Keeping this data up to date is an almost impossible task – which, in itself, leads to concerns over the quality of the data set in use within any application.
However, in order for the LBS market to develop compelling applications requires high quality content. There are a range of issues with the provision of such data for LBS applications including:
- vintage and frequency of updates
- data formats
- licence use terms and conditions
- data standards
