Inogen Alliance through HPC AG has established a GIS tool for the complete petrol station network for Oil! which has included the development of a GIS System according to the needs and organisational structure of the client, and the site visits were undertaken at each station to collect data, maps, drawings, and all paper documents.   All available documents were scanned and uploaded onto the system and the new data was augmented to existing data to provide a comprehensive system. Training of relevant employees was provided and the new tools were added to the system according to new regulations as they were introduced, for example creating "explosive documents" for each.
