GIS\Key™ Geology

Geology Database

The GIS\Key™ Geology Module stores the following geology data:

• Soil units in accordance with the United Soil Classification System (USCS)
• Formations
• Water levels encountered during drilling
• Organic vapor readings
• Well construction details
• Annular fill
• Other field measurements
• Sample information including recovery and blow counts

Geology Graphics and Work Products

The GIS\Key™ Geology Module includes the following ways to present your data:

• Geologic boring logs and a custom boring log template generator.
• Geologic cross-sections
• Structure maps of soil units, formations, or blow count intervals.
• Isopach maps for showing aquifer and contaminated zone thickness.
• Presentation-quality data reports

Boring Logs

Once the geologic data for a sample site has been entered into the users project database, a boring log can be generated in less than a minute. GIS\Key™ provides a standard template to create boring logs, but most users create their own project-specific boring log templates using the custom template generation function included as part of GIS\Key™.

Below is an example of a boring log created from GIS\Key™:

Information in the header portion and the depth-specific (graphic) portion of the boring log can be customized. Header fields shown here include: site id, project name and location, drilling method, site coordinates, date started and completed, casing, screen, and annular fill types, borehole diameter, contractor and geologist information, and space for remarks. Graphic fields include: depth below ground surface, sample number, blow counts, field sampling, material description (geologist's soil descriptions), graphic log showing soil types by hatch pattern, well construction diagram, and elevation relative to mean sea level.

Cross Sections

Users can create an arbitrary section line through their site and then:

a) choose which wells and soil borings to project onto the section line, and

b) whether to show well construction detail and/or lithological hatch patterns.

Profiles are then created automatically from grid meshes constructed for any planar feature, such as geologic formations, bedrock fracture zones, and groundwater potentiometric surfaces. Sections are generated at profile locations so that it is possible to produce drawings across areas of limited subsurface information.

Structure Maps

Structure maps are used to examine the surface or bottom of planar features such as geologic formations, soil types, and other units which influence contaminant migration. Surfaces created simultaneously are used to construct cross sections.

Isopach Maps

Isopach maps show thickness and are used to evaluate feature extent and estimate the volume of contaminated materials.

Geologic Data Summary Tables

Summary tables of geologic data contained in the project can be easily and quickly created within GIS\Key™. Standard tables can be previewed on-screen or printed using the report template provided with GIS\Key™. Users can also create their own templates.

Reports can be be exported in over 30 standard formats, including Microsoft Office, HTML and several database formats, which are easily read by the appropriate 3rd party software. The following table was created with the standard Scout SmartQuery tools and is shown in preview mode. The standard tables printed directly from GIS\Key™ look the same as the preview.

Once data is entered, GIS\Key™ uses the same data to generate boring logs, cross-sections, structure and isopach maps, and summary reports. GIS\Key™ can replace existing geological systems and integrate your project's geological data with the chemistry and hydrology data. GIS\Key™ can also export the data in formats compatible with other programs.
