Geographic Information Systems (GIS) are powerful computer-based database and mapping systems that are useful for storing, managing, analyzing/interpreting, and presenting data and information. GIS is useful in managing and interpreting a large variety of spatial data, particularly geographic and geologic data. GIS is used in many industries from public health, environmental hazard management, transportation logistics, and land use planning.

GIS enables Meiser & Earl, Inc. Staff to access and analyze relevant data from public databases maintained by government and regulatory agencies, to manage and store data collected through field reconnaissance and site investigations, and to analyze data for important spatial relationships.  Meiser & Earl, Inc. also uses GIS to present these data and relationships in meaningful and accessible formats that provide answers to complicated hydrogeologic questions.

Meiser & Earl, Inc. often utilizes GIS to provide important information for groundwater supply and landfill permit applications; managing groundwater and surface water monitoring networks; identifying, compiling, and classifying potential sources of contamination within wellhead protection areas and for source-water protection plans; and to produce groundwater elevation and geologic maps and cross-sections.  Meiser & Earl, Inc. staff integrate GIS with fracture-trace analysis to identify potential well sites and evaluate the suitability of those well sites with surrounding land uses.  Meiser & Earl, Inc. also use GIS in conjunction with engineering drafting software, such as AutoCAD, to assist site engineers with site design and mapping.
