Commission hears ArcGIS wetlands-mapping demonstration
Summary
Joan Spalding demonstrated a free ArcGIS mapping tool using the Black Spruce area and highlighted layers for aerial imagery, LiDAR elevation, National Wetlands Inventory, hydric soils and property boundaries; commissioners discussed using mapping for delineation, easement monitoring, and possible partnership with Chocorua Lake Conservancy.
Joan Spalding gave a demonstration of a free online ArcGIS mapping tool focused on the Black Spruce area, showing layers for aerial imagery, elevation (LiDAR), National Wetlands Inventory data, hydric soils, drainage, wetlands functions, and property boundaries. "Joan shared information from a recent ArcGIS for wetlands training and demonstrated the free online ArcGIS mapping tool using the Black Spruce area as an example," the minutes state. She provided a recording link and contact information for NHDES and noted maps can be customized and saved for planning use.
Commissioners discussed applications for conservation planning, delineation, and easement monitoring. Ned Beecher noted that the Chocorua Lake Conservancy uses a commercial landscape management software that integrates mapping with mobile devices but costs approximately $2,000 annually; commissioners considered inviting CLC to demonstrate that software or partnering to share costs. The Commission asked that staff circulate the recording and contact details to aid future planning.
