Welcome to GRS

  • Lassen Peak, Lassen Vocanic National ParkGRS, 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.


Stumpf Line-point Transect Methodology, Results, and Benefits Presentation at ESA, 2014

GRS has posted the Line-point Methodology Presentation made by Ken Stumpf of GRS, Director Of Resource Management Applications on August 13, 2014 at the Ecological Society of America Annual Meeting in Sacramento, CA., under the Densitometer - Canopy Cover Sampling of our Presentations, Publications, and Software subject.  This presentation was titled "A Venerable Range Management Field Data Collection Technique Used to Develop Plant Community Cover and Frequency Characteristics Provides Unexpected New Levels of Detailed Species-specific Information."

A version of the presentation with notes and comments is available at this link "A Venerable Range Management Field Data Collection Technique Used to Develop Plant Community Cover and Frequency Characteristics Provides Unexpected New Levels of Detailed Species-specific Information - with Comments".

GRS Celebrates 25 Years of Innovation and Success

This August GRS celebrated our 25th Anniversary.  We are appreciative of all the people we have been able to work with over the years and look forward to developing new relationships in the future!  We are also thankful to the many employees we have had over the years who have worked hard to turn out the professional high quality services and products we have delivered to our clients.  We hope that our clients and employees are as glad they had the opportunity to work with GRS as we are that we could work with them.



ESA 2014: GRS NVCS Mapping -

The Future is Now !!

Recently completed National Vegetation Classification (NVCS) vegetation/land cover map data sets for Lassen Volcanic National Park and Redwood National and State Parks include species-specific cover mapping and NVCS detailed associations and alliances.  These new map data sets represent the future of NVCS vegetation mapping and should be considered "state-of-the-art."

On August 14, 2014, Dr. Janet Franklin of Arizona State University presented a summary of "the state of the art and the likely progress of uses of [National Vegetation Classification System] vegetation mapping."  Her presentation was the final portion of the Mapping with the National Vegetation Classification: Purpose, Value, and Method session at the Ecological Society of America Annual Meeting held in Sacramento, CA that was organized by Todd Keeler-Wolf1 and Julie Evens2.

In her summary slide Dr. Franklin showed a progression through time representing the idea that in the past lower resolution imagery provided more generalized NVCS types and that presently "new technologies and data sources," including higher resolution imagery enabled the development of "categorically fine-scale vegetation  information [NVCS classes].  She predicted that sometime in the future, species-specific cover modeling would become available due to improvements in technology, imagery, and processing.


Redwood National and State Parks Vegetation Classification and Mapping Project Completed !  More than Just a Color-coded Type Map!

December, 2013 - The Redwood National and State Parks Vegetation Classification and Mapping Project was completed by Geographic Resource Solutions (GRS) in late June, 2013.  Multiple map data sets representing both raster pixel classification efforts and aggregated stand level mapping efforts were developed under the guidelines of the NPS National Vegetation Mapping Program.  These data sets represent a new level of detailed, quantitative, species-specific information in addition to the standard National Vegetation Classification System (NVCS) type designation(s).  GRS's use of the Discrete Classification methodology also enabled the development of individual species-specific cover component estimates by size class, canopy layer, the "bird's-eye view, and in total; as well as estimates of quadratic mean diameter and stems per acre.

 An article excerpted from the Fall/Winter 2013 Kaleidoscope Newsletter of the NPS-Klamath Network that describes more about this project may be accessed at this link.
