Geographic Information Systems (GIS)
ERA's Geographic Information Systems (GIS) team has extensive experience utilizing GIS for the purposes of data visualization, watershed analysis, environmental engineering, and more. We use GIS for many of our engineering projects to better comprehend project locations and create working exhibits to further enable our engineers. ERA is also capable of embedding georeferenced images from a project location into a geodatabase for easy data visualization. ERA has years of experience creating professional exhibition maps for our projects catered to the specific needs of each client.

With our 3D analyst and spatial analyst toolsets, ERA is equipped with the proper tools necessary for a detailed watershed analysis. When combined with stormwater modeling, the spatial analysis can identify at risk structures along with the degree of impact which can be used to come up with workable solutions for flood mitigation. Additionally, our staff has training and experience working with ArcHydro, HEC-GeoHMS, and HEC-GeoRAS.

​Whether you need to complete a hydrology analysis for an entire village or permitting assistance for an individual property, ERA can assist you with all your GIS needs. See the featured projects below for examples of our GIS capabilities.

MWRD Northbrook Flood Study

The Metropolitan Water Reclamation District of Greater Chicago conducted a pilot study in the form of a Stormwater Management Master Plan for the Village of Northbrook and surrounding unincorporated areas. GIS was essential to this project and was incorporated into every phase of the study.

Klein Creek Streambank Stabilization

ERA created a GIS geodatabase for the Village of Carol Stream to monitor the condition of Klein Creek. The photos obtained from the river conditions survey were embedded into the geodatabase so that each photo was georeferenced and could be pulled up for easy viewing.

Lisle Stream Flow Analysis
Study

The Village of Lisle wanted to identify problem areas that could be impacted by overflow flooding, and ERA completed a stream overflow analysis for entire village. To learn more about the project and the methodology behind the process, click on the link below:
