Communication of geologic data is particularly amenable to graphic imagery. Non-geologists
benefit from well executed drawings and other graphic images that build their understanding of
earth processes and geologic conditions. Though maps are the most common form of geologic graphics,
drill logs and sections are more directly linked to the input data.
From Raw Data to Logs
Stratamodel uses well designed graphics to communicate complex geologic information to engineers
and managers in a form easily grasped by non-geologists. Translation of data collected at the
job site to logs, sections and maps provides a sound basis for design decisions at the office.
The front line of subsurface geologic data collection is the drill, CPT or trench site. Stratamodel
excells at rendering these data into easy to read graphic logs.
Logs represent a linear sequence of subsurface sample points
From Logs to Sections
Often the job of logging downhole geology during a drilling program is delegated to the least
experienced (least espensive) geologist or technician available. Frequently, more than one novice
logs drill holes on the same site. It is false economy to spend thousands of dollars on a drilling
program and then degrade the data through inconsistent or inaccurate observations and measurements.
Based on decades of experience, Stratamodel provides consistent, accurate measurements within the
limitations of the drilling technology used in the investigation.
Lining up drill logs and correctly correlating subsurface horizons follows from accurate reliable downhole
data. Stratamodel provides finished sections during and at the close of drilling programs.
Geologic sections provide a view of slices through the subsurface.

From Field Maps to GIS
Maps have evolved from static, paper based analogs of the real world to dynamic digital representations
of the most recent data available. The digital world has opened the potential for geologists and engineers,
to simulate outcomes of alternative courses of action without costly real world consequences. One of the
greatest challenges of the past was keeping project maps up to date. This is less of a a problem for
those who have implemented a geographic or geologic information system. As new data are collected and
added to a project database that is harnessed to a map engine, real time information can be disseminated
across a network to all project personnel as maps, tables, and graphs.
Stratamodel maps range from hand drawn field maps to digital maps linked to a backend database in a
geographic information system (GIS). Stratamodel uses state of the art software such as
ESRI ArcMAP,
Autodesk Map 3D,
and Techbase to design and implement GIS based
on field mapping, remote sensing, drilling, geochemical surveys and geophysics. Stratamodel in
partnership with West Arete Computing provides web-based
GIS using PostGIS and Ruby on Rails.
