Geographic Resource Solutions
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.
GRS consultants have extensive experience in all phases of the entire GIS life-cycle. Our consultants understand issues and concerns regarding GIS mapping projects and offer valuable insight on GIS applications. Available system resources and on-line projects also allow GRS to prototype system designs and application workflows before they are implemented.
GRS is the designer and manufacturer of the GRS Densitometer™, a tool used for the
estimation of vegetation cover. The GRS Densitometer™, when used with either
line-point or line-intercept transect sampling, combines horizontal and vertical
vegetation sampling, thereby enabling the collection of resource information
across the landscape (horizontally) at different canopy levels (vertically).
This technique provides estimates of cover for any element in a
forested environment such as: trees, shrubs, herbs, downed-woody material,
fuels, and snags.
"... most accurate, least expensive, and most easily applied..." - The line-
point transect method of sampling has been shown to be accurate, objective, and
repeatable between observers. In May of 2015, the Food and Agriculture
Organization of the United Nations concluded in a research study of four
different methods of assessing canopy cover characteristics that the line-point
transect was the "most accurate, least expensive, and most easily applied among
the four methods tested. This method is scientifically accurate and records
forest canopy and floor cover as a set. The instrument used in this method, the
GRS Densitometer, is small, light and easy to carry and comparatively cost
GRS has extensive experience in remote sensing, image interpretation, and image classification through projects ranging from a few hundred to millions of acres. GRS specializes in resource and land cover classification using satellite imagery and we have become internationally known for our innovative techniques and ability to perform highly detailed and accurate land cover classifications in difficult situations.
