Mapping and Graphic Solutions for the Energy Industry

Welcome to Hart Energy Mapping & Data Services (formerly Rextag).

For years Rextag had been a leader providing the energy industry with excellent mapping products and services, now with the recent acquisition by Hart Energy, one of the largest energy publishing companies in the US, Rextag joins a larger and stronger family of energy products that similarly expand our product offerings.

Our Products and Services all tie into our two main proprietary databases that we diligently maintain and update daily: our mapping GIS (Geographic Information Systems) and our Daily Gas Flow Database.

Hart Energy’s Energy GIS database is the foundation for all our printed map products and custom mapping, it consist of the most complete database or energy infrastructure in North America. Additionally, you can license the right to use our GIS database for your own internal mapping needs.

Lastly, the Daily Gas Flow Database provides users access to all public gas flow data and information on a daily basis via our web-based subscription service to GasMapX.
