Environmental Research, Inc. (ERI), a woman-owned small business founded in 1993, is a full service geospatial company specializing in current and historical imagery analysis, photogrammetry, geographic information systems, and litigation support for environmental investigations and natural resource mapping.
ERI services include the acquisition and stereoscopic analysis of aerial photographs and other remotely sensed data ranging from the 1930’s to the present. Depending on the focus of the analysis, a full range of remotely sensed data can be used, including black& white, color, and color infrared aerial photographs; thermal infrared aerial imagery; and multi-spectral satellite imagery.
Applications for ERI’s current and historical imagery analyses include:
Building on years of image and geospatial data integration experience, ERI utilizes leading edge software to produce multitheme, multi-source GIS datasets. Our GIS personnel have extensive experience using the Leica Photogrammetry Suite and ERDAS Imagine software to orthorectify and mosaic current and historical aerial imagery, generate 3-D visual illustrations of current and historical photogrammetric data, and to georeference maps and other spatial data. Through on-screen digitizing, we generate aerial imagery analyses and GIS datasets using ESRI ArcView and ArcGIS software.
ERI utilizes both softcopy and analytical stereoplotting capabilities, providing a wide range of photogrammetric products generated from current and historical photographs that include:
The professional analysts at ERI have conducted hundreds of environmental forensic investigations to support CERCLA/RCRA cost recovery, environmental insurance claims, natural resource damage assessments, and federal government enforcement and defense. Through our well-established methodology of integrating current and historical imagery analysis, photogrammetry, GIS, and 3-D illustrations, we strive for the highest degree of accuracy, scientific objectivity, and completeness.
