GIS Analysis

Our complex analyses of diverse geospatial datasets help inform your project design and management decisions.

A Geographic Information System (GIS) is a system of software that captures, stores, analyzes, and presents digital data that corresponds to real-world, geographic locations. With over 25 years of accumulated experience working with GIS, our GIS Mapping & Analysis group’s services are integral to all our scientific investigation and project planning. Our mapping professionals are also proficient working within the AutoCAD environment and can facilitate accurate geo-referencing so that your project’s data can be transferred between GIS and other software like AutoCAD, Google Earth, and Adobe PDF.

Our GIS department specializes in a number of specific services, including:

Basic Mapping & Existing Databases

Our GIS abilities and map output begin with the basic display of project locations and spatial relationships to existing data sets. This basic core service is the first step for more complex analyses off of which other GIS services build.

Mapping, Managing, and Remote-Sensing Spatial Data

A number of in-field and desktop based technologies allow WRA to efficiently and accurately create spatial datasets for any project. This might include fine-scale GPS mapping of individual resources in the field or large-scale automated mapping of vegetation communities over thousands of acres using aerial photograph interpretation software. Depending on your specific circumstances, we will help you identify the best approach.

Spatial Analysis

WRA excels in conducting complex analyses on geodata to answer specific questions applicable to your project’s needs. Whether it is a simple area calculation of the impact of a new bridge to a creek or a complex multi-step model that analyzes grazing potential for a several thousand acre ranch, our staff repeatedly develops innovative new tools to quickly and efficiently solve your problems.

Topographic Surface Modeling, Analysis, and Visualization

Our GIS staff uses the latest software to conduct topographic analyses. Topographic analysis is critical for many projects.  It is used, for instance, for surface modeling to assess flooding potential and sea level rise, viewshed analysis, slope analysis for new road or trail planning, and solar radiation analysis to inform restoration planting palettes.

Automated Spatial Modeling for Complex Datasets

When analyzing large, complex spatial datasets, automated GIS modeling is often required in order to provide a cost-effective and rapid product. We have experience in creating a number of complex automated models to answer such diverse questions as:  what are cattle stocking rates given available forage; what are the social, environmental, and physical limitations for a county-wide trail corridor; and how does one identify priority lands for conservation planning.
