Geographic Information Systems (GIS) is one of the primary mapping tools used by NJDEP and environmental professionals. GIS is an efficient way to analyze site-specific data and understand regional environmental issues. The NJDEP provides a variety of GIS datasets that are available as free downloads through the Bureau of Geographic Information Systems. If you can’t find the dataset you are looking for from the NJDEP Bureau of GIS, the Bureau also provides a list of additional resources, including county GIS departments, independent and non-profit organizations, and federal agencies. Additionally, the New Jersey Geographic Information Network (NJGIN) provides downloadable statewide data including aerial photography and parcel information that are helpful starting points for generating base maps. Links to selected data resources are provided at the bottom of this article.
Downloaded datasets can be viewed in ESRI ArcGIS software. For users without ArcGIS software, a free data viewer called ArcGIS Explorer is available for download online. NJDEP hosts NJ-GeoWeb, which is an interactive mapping tool similar to GIS that can be accessed through an internet browser. GeoWeb provides a user-friendly interface with options to view many of the downloadable GIS datasets.
NJDEP requires GIS deliverables with many types of submissions, including deed notices, classification exception areas (CEAs), well receptor searches and immediate environmental concerns (IECs). Submission of GIS files in accordance with the NJDEP Administrative Requirements for GIS Deliverables ensures data accuracy and quality and means that data will be mapped in the correct location every time.
JM Sorge is experienced with using GIS to develop environmental solutions for a wide variety of investigations and remediation projects. From development of site maps, to complex data analysis and spatial compliance averaging problems, GIS is an important part of the solution.
