Geographic Information System (GIS) 



Aries relies on GIS technology to manage large amounts of environmental information within a geographic database or geodatabase.  Using the ESRI ArcGIS tools, we are able to combine, analyze, and present multiple layers of spatially-distributed data and information, such as environmental measurements, with pertinent physical features of the study area.  Aries uses GIS software as a platform to perform the following: 

  • Evaluate spatial relationships, patterns, and processes of geologic, climatic, hydrologic, geographic, biologic, and environmental data and information;
  • Increase informed decision making capabilities while streamlining data collection and interpretation processes;
  • Geostatistical analysis of spatial data to improve data collection and strengthen conceptual site models;
  • Model contaminant transport in groundwater, surface water, sediment and air to present clear graphic representations of the pertinent subsurface features and the contaminant transport pathways; and
  • Prepare digital maps, plans and mapped data to share with our clients via the internet.

GIS incorporates scientific tools and applications we use for geospatial analysis of environmental geographic data as follows:

  • Surface Interpolation, create a continuous surface from sample locations and develop probability distribution from existing sample measurements;
  • Efficiently measure height, magnitude, and/or concentration of environmental or physical measurements of a geographic data set;
  • Evaluate interpretation methods for study area specific data. Interpolation methods range from inverse distance weighted to kriging;
  • Display and analysis of time series data by integrating temporal data within GIS; and
  • Prepare three-dimensional composites of the conceptual site model including lithologic, geologic structure, contaminant concentration, and water-level data using accepted algorithms to interpolate between data points.

Aries has over 30 years of experience developing environmental simulations including: Predictive models to approximate future site conditions; Interpretative models that typically provide a framework for studying environmental system dynamics; and Generic models used to analyze hypothetical environmental systems.  Examples of Aries’ GIS applications include:

  • Measuring historical river channel migrations rates and beach front erosion/migration changes and rates;
  • Preparing three-dimensional (3D) visualizations of subsurface geology and contaminant distribution including contaminant probability distributions;
  • Detecting changes in a particular area or feature over time data using data obtained from satellite imagery/remote sensing;
  • Preparing co-occurrence maps to identify the proximity and magnitude of significant data features and attributes;
  • Conducting proximity evaluations of historical land use information with current recognized environmental conditions;
  • Integrating Global Position System (GPS) data with site features and attributes; and
  • Conducting forensic geostatistical analysis of contaminant characteristics and distribution relative to contaminant sources.
