April 2023:  Updates to the NH Method

The NH Method was most recently updated in April 2023. The substance of the NH Method is unchanged - edits were made to update dead web links and to update the documents with GRANITView as the primary resource for accessing data layers and creating maps for answering questions in the NH Method.

GRANITView includes the new Wetlands Mapping Tool (found in the Custom Tools tab) for drawing wetland and watershed boundaries, calculating those acreages, and a buffer tool to show the 500 ft (or other width) zone of influence.  This updated version of GRANITView  replaces the outdated NH Wetlands Mapper.
