Geographic Information Systems (GIS)

GIS encompasses a wide array of capabilities including the storage, management, analysis and display of data that can be tied to a spatial location. The use of a GIS can be used on a wide array of projects from simple site mapping or creation of a road map, to complex analysis and projections of environmental contaminants or population growth.

Global Positioning Systems (GPS)

GPS has become more familiar to the general public in the past few years with the spread of in-car navigation equipment. GPS is typically used in a consulting firm to locate features in the field so they can then be brought into a GIS. Professional-grade GPS equipment can record features with sub-meter or even more precise accuracy when required.

Several clients rely on Two Springs for collection of field data via GPS units. Two Springs utilizes both 3-5 meter and sub-meter GPS units (depending on your accuracy requirements) to collect field data for inventory and GIS analysis.

Cartography
Cartography = map making. Do you need a map of your property or study site? Two Springs has developed maps for numerous clients to fulfill many objectives. Maps can answer many questions from "How do I get to my property?" to "What is on my property?" to "Where is this water runoff coming from?" and “Where is the contamination and where will it migrate to?”

Spatial and 3-Dimensional Analysis

A GIS, in conjunction with data collected with a GPS, can be used to analyze, model and display information in either a 3D or 2D perspective. 2D spatial analysis within a GIS is a valuable tool in business to predict movement of environmental contaminants or to determine the least expensive and most efficient way to route a new road.

3D analysis, and more specifically 3D display of data, has become more familiar to the general public with exposure to Google Earth and other 3-dimensional display of data. The real world is 3D, but a computer screen is typically 2D. 3D display and analysis tools within a GIS enable one to take 2D data to a 3D display, making data ‘come to life.’
