Status	Commercial
Description	GW Contour is a data interpolation and contouring program that also incorporates techniques for mapping velocity vectors and particle tracks. Data input features: Import data from various sources including ASCII (TXT, ASCI, DAT, TAB,), ESRI Points Shape (SHP), Excel (XLS), Access (MDB), Surfer grid (GRD). Import various X,Y,Z data types including water levels, soil porosity, aquifer hydraulic conductivity, water quality concentrations, contaminant concentrations, ground surface elevations, recharge, etc. Project units include Head (m, cm, ft), Hydraulic Conductivity (m/s,cm/s, m/d, ft/day), Concentrations (mg/l, ppm, ppb, meq/l, ug/l, mg/kg), Velocity (m/s, cm/s, m/day, ft/day), Time (sec, days, months), Coordinates (cm, m, ft). Import and geo-reference a variety of raster images for use as project base maps (BMP, JPG, TIF, GIF, SVG, EMF, PNG). Supports import and export of AutoCAD files (DXF). Define project extents (Xmin, Xmax, Ymin, Ymax). Define number of particles on a circle. Define number of particle points on a line. Define vertical exaggeration (X:Y ratio). It incorporates the most commonly used 2D data interpolation techniques for the groundwater and environmental industry: Natural Neighbor, Inverse Distance, Kriging and Bilinear. Applications: Graphical mapping and reporting of groundwater levels. Preliminary interpolation and contouring of contaminant concentrations (groundwater, soil, or air). Assessing groundwater flow direction and magnitude. Calculating the direction and rate of groundwater flow. Contouring data obtained from pumping tests, dataloggers, groundwater monitoring events, weather stations, groundwater models, borehole logs, etc. Gridding ground surface elevations for use in groundwater flow models or GIS. Analyzing exposure pathways when assessing human health risk. Comparing conceptual interpretations with calculated interpretations.
