GRS, located in Arcata CA, was founded in 1989 to provide superior-quality resource information development, technical, and consulting services.

GRS is a leader in the implementation of ecologically-based field data collection methodologies designed to provide comprehensive, quantitative, and detailed species-specific cover estimates of the botanical and abiotic features that comprise the ecosystems we must accurately describe.

GRS offers "state-of-the-art" natural resource inventory and land cover mapping services based on the application of our unique Discrete Classification Mapping Methodology in combination with traditional vendor provided applications; GRS maps (not models) species-specific cover as a continuous variable, along with other landscape and abiotic characteristics to develop comprehensive resource inventory information.

GRS offers complex resource analyses that include natural resource inventory, growth projection, long-term sustained yield projection, long-term harvest scheduling, and change detection.

GRS offers total GIS solutions including GIS consulting; data set development, analysis, quality control, and processing; application development; and software sales.

GRS has extensive experience designing and developing superior solutions for a wide range of applications, users, and organizations.
