Why OneMap

OneMap is the industry source for reliable surface ownership information used in GIS-based decision support processes and tools.

Providing a robust GIS data library focused in core U.S. resource play regions, OneMap's surface ownership information helps organizations improve planning and routing decisions and operations, increase land research productivity, and decrease data collection and field research costs.

Unlike other surface ownership data providers, OneMap directly serves of the U.S. energy industry by continually improving the quality of the data and expanding its coverage based on drilling and leasing activity.

Premium GIS Datasets

OneMap provides up-to-date surface ownership GIS parcel datasets attributed with property tax information. All GIS datasets are normalized and delivered in OneMap's "Energy Data Model" for consistency and ease of integration and internal distribution. OneMap has dedicated its resources to improving and expanding surface ownership information coverage in the active U.S. resource plays. With the use of leasing/drilling activity information, along with their proprietary county and parish information resource database, OneMap has developed a system where existing datasets are refreshed and new priority datasets are added when requested and/or available.

Instant access to a web-based mapping interface allows brings accessibility to field and other non-technical users without dedicating additional human and technology resources to developing internal applications and managing the required data. Field personnel typically spend a majority of their time on the road and in county courthouses researching manually. MapLink provides an instant head start to locating and researching subject properties, and reduces ownership research cycle-time from hours and days down to minutes.

  • Instant online access to straightforward ownership research and mapping tools.
  • Search graphically or by lat/long, XY, survey, etc. to quickly locate project sites and subject properties.
  • Point and click to select property parcel(s) or select by radius or corridor.
  • Print and export selected property owner contact reports.
