Geospatial Technology Services
We use state-of-the-art geographic information system (GIS) and image processing software to combine data from many sources into data sets to analyze and map the relationships between proposed or existing project facilities and environmental and regulatory constraints. These powerful analytical tools allow for comparative analyses and mapping of environmental impacts resulting from various project alternatives.
In addition, HBG uses the GIS analytical process to project changes in site baseline conditions over time and anticipate challenges to development options and future operations from potential natural resource damage scenarios or long-term environmental changes due to factors such as climate change.
GIS data sets may include aerial and satellite imagery, CAD-based engineering and architectural plans, GPS data gathered in the field, data from existing environmental GIS databases, and biological and regulatory constraints data.
Types of GIS Based Analysis Performed by HBG Include:
Direct Imagery Interpretation
Automated Digital Processing (Supervised Imagery Classifications)
Multi-Spectral Imagery
Project Impacts
Corridor / Linear Route Selection
Change Detection
Project Alternatives & Site Selection
Potential Mitigation Alternatives
Natural Resource Damage Assessment
