LFR provides GIS products and services to deliver accurate, usable, and economical results
to clients.

LFR uses ESRI GIS software for clients whose main objective is to visualize and query data for timely and cost effective decisions. We apply large- and small-scale GIS technology (ArcGIS, EVS) on powerful NT workstations for this purpose, as well as to analyze information and incorporate additional data structures. Our approach is a standardized process through which information management is our service model protocol.


LFR employs GIS in many different facets of environmental work including investigations and remediation to help visualize collected sample data. As warranted, these data can be viewed in relation to geology, vegetation, land use, and many other aspects. Additional analysis can be applied to identify target areas for further investigation. GIS also has significant value for other environmental services including ecological restoration, litigation support, site closures, facilities management, planning, and many others.

With the focus on successful integration of enterprise wide spatial data management solutions, LFR's GIS and database staff of analysts, programmers, and technicians provides a full spectrum of GIS services-from planning and specialized project support through modeling and analysis to full implementation.

Our comprehensive experience nationwide gives LFR a wide breadth of GIS knowledge including:

  • Data model creation for GIS data to precisely characterize surface geography organized in a Watershed Data Management System (WDMS) for state-of-the art analysis, visualization, and 3D animation
  • Public utilities/facilities management - mapping, modeling, and management of public utilities, particularly in water and sewer systems, from GIS selection to development of turnkey systems for total integrated management
  • Urban planning needs such as mapping and managing vast databases with land use, general plan, zoning, and assessor's information at the sub-block and parcel levels
  • Base realignment and closure for base cleanup, including work with historical aerial photographs and specific considerations for structures
  • Creating and documenting large databases for various Superfund sites, including integration with hydrogeologic modeling, Potentially Responsible Party identification, and U.S. Environmental Protection Agency interaction
  • Digital Elevation Model (DEM-TIN) creation for natural resource, wetlands, watershed delineation
  • Siting and planning studies for landfills, toxic waste deposition, pipelines, monitoring wells, electrical transmission lines, and other installations and facilities
  • Use of existing data sets to locate potential Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) sites, and develop models of leaching and runoff
  • Site investigations/remedial investigations for properties ranging from small sites to those encompassing many square miles with hundreds of sample points, from densely populated urban areas to unique, near-shore areas
  • GIS database development/figure production for Phase I Environmental Site Assessments (ESAs) for potential school sites
  • Research data aquired in the identification process to produce national and state specific client maps and presentations for EBDC study sites revealing information about specific watersheds, topography, crop density, where that information did not already exist
  • Geodatabase development and specialized GIS programming for end-user systems
  • GIS system evaluation and selection
  • System integration in regard to the specific needs of GIS systems and their databases


INTEGRATION WITH RELATED TECHNOLOGIES

The value of GIS increases as it becomes integrated with related technologies that add data to the GIS information base. These technologies establish a broader and more accurate map foundation for other spatial data to be analyzed. LFR has demonstrated and working experience interfacing GIS to other computer-based technologies, including:

  • Surveying (COGO)
  • Global positioning systems (GPS)
  • Computer-aided design and drafting (CADD)
  • Automated mapping/facilities management (AM/FM)
  • Hydraulic/hydrologic modeling (EVS, MODFLOW)
  • Internet web mapping & operations management system (OMS)
  • Relational database management systems (RDBMS)
  • Mobile GIS with PDA & TabletPC (ArcPAD/Trimble)
  • Geocoding (U.S. Census TIGER)
