EnviroInsite Specifications

Data Storage and Queries – Well construction, sampling location, geological information and environmental data are stored using relational database conventions -- reducing data replication, improving control over data quality, and simplifying application of data queries within the code. Data queries are facilitated by fill-in-the-blank forms that generate complex SQL queries based on sample location, depth, elevation, well name, screen name, date, parameter and minimum, mean, maximum, first or last recorded value. Data is stored in either Microsoft Access or Microsoft Excel file formats. Export links to the standard EnviroInsite have been generated for both EQuIS 3 and EQuIS 5.

Mapping – Reads and displays conventional vector file formats including 3D or 2D versions of ESRI shape files, AutoDesk DWG and DXF files, and enhanced metafiles. All conventional bitmap files can be imported for use in base maps, including PNG, BMP, TIF and JPG. Microsoft World files can be read for display of scaled and rotated TIF and JPG files in world coordinates. Vector files and bitmap files can be draped to ground surface defined either by ground surface data stored in the centralized database or external data files.

Advanced User Interface – Interface allows for complete user control over location of well labels, posted values, graphs, and tables to circumvent label-overlap problems endemic to other visualization codes. Complete file save/open capabilities remember session with hot-link to data files to allow for automatic updating of generated graphics. Tree-control menu structure allows individual plots and components of these plots to be turned on or off by operation of the check boxes in the tree menu. EnviroInsite can also be run remotely using Visual Basic or Visual Basic for Applications.

Profile Views – Cross-section or profile views are constructed by point-and-click on the plan view map display. The profile is automatically generated, with ground surface and bedrock surfaces generated from external data files or by automated queries of the ground surface values stored with the well construction data. The mapped profile trajectory is shown on the plan map and on a map inset in the profile view. The vertical exaggeration is set to a default value to fit the window, although this default value may be specified by the user at any time. There is no limit on the number of panels that can be used in display of the profile views. User specified distances from the profile can be set for selection of wells and other features to be displayed on the profile.

3D Views – Three dimensional, perspective images of the site are enabled with control over the direction and intensity of lighting, translucence of objects, and viewer location and elevation. The 3D view can be set to one of four default view perspectives or rotated by the user by dragging the mouse across the screen. Three-dimensional viewing features including 3D contours, 3D surfaces, geologic surfaces, fence diagrams, geologic models, wells, borings, 3D-classed post plots, pie charts and 3D axes.

Contouring – Two-dimensional plan- and profile-view contours can be constructed for both environmental data and geologic surfaces. Three-dimensional contours can be generated of environmental data. Contouring occurs in a single step, by the interpolation of measured values on to a user-specified two-dimensional or three-dimensional grid and the subsequent construction of fill or line contours. Contour value labels printed at user specified inter-label distance or manually specified by point-and-click. Two-dimensional contours can be generated as translucent objects for visualization of underlying base maps. Interpolation methods include three-dimensional kriging or inverse distance, with full control over anisotropy, variogram model and other interpolation parameters. The horizontal extent of contours can be controlled either by setting the dimensions of the underlying interpolation grid to the area of interest or by drawing a polygon around the area of interest.

Gradient Vectors – Vectors can be plotted illustrating the gradient field of environmental data. Typically, this is used to indicate the direction of water flow based on water level measurements. Gradient arrow size and color are controlled by the user. The length of the vectors might either be fixed or scaled to the magnitude of the gradient. The magnitude and direction of vectors is calculated based on values interpolated onto a rectangular grid. The dimensions and resolution of the grid are specified by the user. Gradient vector construction uses the same interpolation methods and controls as the contouring functionality.

Fence Diagrams – Stratigraphic data displayed as 3D multi-panel fence diagrams or 2D fence diagrams on a profile view. The fence diagram layout is specified by point-and-click operations on a plan-view map. The diagrams are generated by interpolation of contact surfaces from stratigraphic data onto the fence surfaces. The user has complete control over color and translucence of fence diagrams. It is also possible to drape bitmap soil images over fence diagram surfaces. Three-dimensional geologic models can be generated by indicating that the defining fence-diagram polygon should be closed. The ground surface data is then also plotted to generate the closed geologic model image.

Time History Charts – Geographically-referenced time history charts can be generated in plan- or profile-views of one or more constituents. The charts may also be plotted to a new window for printing of one or more plots on a single page. These page charts can either contain multiple parameters for a single sampling location or multiple locations for a given parameter. The user has full control over the chart’s background color, text height, axis limits, increments, and formatting. Multiple axes can also be used for plotting of data with differing units or limits.

Radial Diagrams and Pie Charts – Radial diagrams and pie charts present the relative concentration of multiple constituents at a given location and sample interval. Pie chart thickness can be set by the user for display of the pie chart in a 3D view. Radial diagrams are particularly useful for display of relative concentrations for constituents with order of magnitude difference in value. This is facilitated by log-scale axes on the radial diagrams.

Stiff and Piper Diagrams – Diagrams for analysis of geochemistry data. The Stiff diagrams present the relative concentration or primary cations and anions in millequivalent per unit volume, with cations to the left of the diagram and anions to the right. Stiff diagrams may be plotted adjacent to the sampling location on both plan- and profile-views. As with well labels and other charts, the plotted location of the stiff diagram is controlled by the user to prevent overlap of diagrams. Piper diagrams plot cations and anions on ternary plots in a conventional format. The sampling location name may be optionally displayed on the Piper diagram.

Output – Layouts constructed with title-box, scales and legends are displayed for report-style graphics. Export capabilities to BMP, TIF, PNG or JPG bitmap file formats, DWG, DXF or Metafile vector file formats. Copy-and-paste through clipboard to other applications. Print to any Windows compatible printer or plotter.
