Geographic Information Systems and Data Management Services


Walsh provides Geographic Information Systems (GIS) services, remote sensing, and database management for a variety of environmental projects. In addition to using GIS as an integral part of most of our projects, we frequently provide stand-alone GIS services to client companies.

Our GIS and data management services include:

  • Resource mapping
  • Change detection
  • Generation of maps
  • Production of electronic atlases that link databases (analytical data, etc.) with text, photos, and drawings
  • Materials volume estimates (aggregrate, mine tailings, etc.)
  • Statistical analyses of geochemical sample data
  • Spatial analysis of possible contaminant sources
  • Management of large environmental databases
  • Mosaicking of satellite and aerial images
  • Web-based internet mapping and applications
  • Visual Resource Management
  • Mobile Mapping applications
  • 3-D Modeling


Emergency Response/Planning

WALSH has developed remote sensing, GIS and intranet tools to help our clients with emergency response and disaster assessment.


Environmental Management Systems (EMS)

Walsh has constructed GIS-based Environmental Management Systems that are customized to client needs. These systems provide web-based access to spatial data and complex databases.


Impact Assessment and Baseline Studies

Walsh uses GIS and remote sensing tools to support environmental impact assessments and baseline studies.


Pipelines and ROW

Walsh has used a variety of GIS tools in conducting planning, impact assessment, and monitoring projects for pipelines and other linear projects.


Vegetation Monitoring and Change Detection

WALSH is using remote sensing and GIS technologies to study and monitor vegetation growth rates and change detection and analysis projects.


Visualization and Visual Modeling

Walsh conducts modeling of visual impacts from projects such as wind farms, oil exploration and production, and transmission lines.  We also do photosimulation and GIS-based "fly-throughs" of proposed projects.
