Geographic Information Systems (GIS) are an integral part of environmental work. GIS can be used to prepare for field work by identifying the general location of wetlands and/or potential resources such as threatened and endangered species. This allows for planning access points to a site and areas that may require further documentation. Such information is valuable to a project because it saves time and money when scientists are on the ground delineating wetland edges. Land + Coastal uses GIS and CAD (Computer-aided design) where appropriate to convey data and information to our clients and regulatory representatives.
