What We Do

Routine tasks completed quickly and accurately.
Intricate tasks completed efficiently and accurately.

Geographic Information Science (GIS) - 
We provide services from basic map digitizing to custom GIS software development. Our consultants have been using GIS as a tool to solve environmental problems since 1986. We deliver applications in air quality, ecosystem management, water quality, wildfire modeling, and emergency management.

  • Specialty in “converting” non-spatial models to run using map data in a GIS: For instance we helped the California ARB incorporate a state-wide map of forest fuel loadings into the First Order Fire Effects Model. The ARB now uses this straightforward GIS tool to calculate fire emissions given any fire perimeter in the state.
  • Extensive use of GIS overlays for augmenting and quality assuring “raw” collected data: For instance the Western Regional Air Partnership can overlay forest fire activity data on fuel maps to acquire fuel loadings where the data is lacking.

Remote sensing research -  We have an international reputation in remote sensing research including participating on the science teams for the United States’ MODIS satellite as well as China’s first earth observational satellite. We specialize in algorithm development for satellite and airborne sensor types including visible spectrum, hyperspectral, and LiDAR datasets. Research topics include:

  • Land use mapping and change detection for global environmental change,
  • Automated feature extraction, map classification, and numeric prediction, and

  • Combining digital photogrammetry and multispectral remote sensing techniques to derive precise forest measurements.

Remote sensing application -  Our group collaborates for satellite-based acquisition with government agencies (NASA, USDA Forest Service, National Park Service) and tasking fly-overs with the private sector contractors (HJW GeoSpatial, Inc.). Berkeley Environmental Technology is familiar with the advantages and shortcomings of various data products and recommending the most cost effective data for the task at hand. For example we built a high-resolution vegetation dataset for Point Reyes National Seashore by augmenting existing commercial imagery with a special fly over.

Specific Project Experience

Forest fire emission inventories -  Inventories of wildland fire and agricultural burning for air quality SIPs, regional haze planning, and global warming analysis was pioneered by our consultants.  We have the ability to produce national, regional, state, local, and federal lands fire inventories for criteria and green house gas pollutants. We have inventoried wildfire, prescribed fire, agricultural burning, and rangeland burning for the WRAP, California ARB, and Pt. Reyes National Seashore. We have the experience collecting fire activity data and burn practices from the agricultural industry and federal, state, and tribal agencies. We are accustomed to merging different quantitative and survey data to finalize and deliver emission estimates. Our group has implemented future fire scenarios for air quality planning. We're happy to hand off GIS, database, and spreadsheet tools for your future emission inventory updates.

LiDAR-based forest carbon mapping - Spatially resolved inventory of carbon stocks in forest biomass.  For use in climate change and registry projects.  Our automated mapping procedure utilizes satellite imagery, airborne LiDAR scanning, ground LiDAR collection, and forest plot survey by a Registered Professional Forester.

Computer clusters and storage information technology for government and small business operations -  We design and build 10+ computer Windows batch clusters to run environmental models (including ISC, AERMOD, and CALPUFF). We have engineered hourly/daily backup systems to terabyte RAID servers. Berkeley Environmental Technology's specialty is utilizing commodity hardware and straight forward software to easily run the models and integrate the output.

Industrial air quality calculations -  Our consultants are familiar with stationary source air permits for gold mining, petroleum exploration, natural gas gathering, oil-shale recovery, coal- and natural gas-fired power generation, and VOC coating facilities. Our staff has consulting experience with minor source/Title V/PSD regulatory analysis (40 CFR, NSPS, MACT, state regs, etc.), source characterization and emission calculations, original permitting strategies, and we are familiar with the EPA sanctioned air dispersion models (ISC, AERMOD, CALPUFF).
