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.


GRS Densitometers for Education Program

GRS is pleased to announce the continuation of our GRS Densitometers for Education Program.  Since 2009, GRS has been providing GRS Densitometers to qualified academic institutions for reduced cost or no-cost.   As of 2014 GRS has provided the GRS Densitometer to over 30 academic institutions in six of the seven continents of the world.


GRS Releases Galena Forest (Biomass) Inventory and Management Plan Report

January, 2013 – In late January Geographic Resource Solutions (GRS) released the Galena Forest Inventory and Management Plan Report developed for a consortium of the Louden Tribal Council, the Galena School District, and the City of Galena, Alaska. This report describes the detailed vegetation/land cover/biomass inventory developed for approximately 1.25 million acres of wildlands in the vicinity of Galena that was used to estimate forest growth and biomass availability and project the magnitude and sustainability of future harvest levels through the end of this century. This information will provide the basis for a determination of the feasibility of developing biomass fueled power generation for the community of Galena. This Project was funded by grants from the Alaska Energy Authority and the Bureau of Land Management.


GRS's ASPRS 2012 Presentations Posted

GRS has recently posted the two presentations made by Ken Stumpf of GRS, Director Of Remote Sensing Applications, under the Remote Sensing Page of our Presentations, Publications, and Software subject.  These presentations were titled Accuracy Assessment, "The Emperor's New Clothes," and Other Fairy Tales and The Lassen Volcanic National Park Comparative Mapping Project - Preliminary Results.

Two versions of The Lassen Volcanic National Park Comparative Mapping Project - Preliminary Results were posted.  One version has notes that describe information shown on many of the slides, whereas the other version does not.

For further information about these presentations or the materials contained within them, contact Ken at GRS by email or phone.
