2015 PREP Impervious Cover Update
DescriptionUsing on-screen editing to capture changes between 2010 and 2015, GRANIT has updated the 2010 high resolution impervious cover data for the 52 PREP communities in Maine and New Hampshire. In New Hampshire, 1-foot resolution orthophotography acquired in the spring of 2015 provided the basis for the update. For towns in Maine, 1-meter NAIP orthophotography acquired in the summer of 2015 was used to support the revision.  More

A Landscape Scale Assessment of NERRS Marsh Resilience
DescriptionGRANIT is part of a team working to develop GIS-based tools for assessing the long-term resilience of tidal marshes within the National Estuarine Research Reserve System (NERRS). NERRS is developing tools to assess marsh resilience to sea-level rise and other environmental changes using monitoring protocols employed at selected study sites. It is important for researchers to understand how representative the selected monitoring sites are in the context of each Research Reserve and its broader ...   More

Broadband Mapping in Northern NH
DescriptionFunded by the Northern Border Regional Commission, this project continues the efforts of the NH Broadband Mapping & Planning Program to enhance economic development in NH by addressing the issues of broadband access, affordability, and utilization. To do so, GRANIT will be 1) mapping and analyzing broadband availability in 4 NH counties (Coos, Grafton, Carroll, and Sullivan) and 2) working with communities, organizations, and other stakeholders to enhance broadband access and adoption in order ...   More

NH GRANIT LiDAR Data Management
DescriptionNH GRANIT will be working with NH DES to archive and make available to the public a statewide LiDAR collection. In addition, derivative data sets will be generated, most notably, 2-foot contour intervals by HUC-10 watershed unit. We also anticipate generating both first return and difference (difference between first and last return) elevation models.  More

Pollution Tracking and Accounting Pilot Project (PTAPP) - Great Bay
DescriptionWorking the NH Coastal Program, the UNH Stormwater Center, the UNH Research Computing Center, communities in the Great Bay region, regional planning agencies, and other partners, GRANIT will be developing an online PTAPP tracking database and web interface. This effort represents Phase II of a long-term project that seeks to work with NH's communities in developing and standardizing reporting and accounting tools that are needed for compliance with EPA non-point source regulatory requirements.  More

Space Grant - 2017
DescriptionObject-based image analysis (OBIA) methods are being used to update the 23-class New Hampshire Land Cover Assessment for three towns in central New Hampshire: Belmont, Laconia, and Tilton. GRANIT is exploring the use of generalized LiDAR-derived land cover (generated from the 2016 NH Space Grant project) as a classification enhancement to the Land Cover product. Past experience indicates that problems arise in defining medium and low density urban features from 30-meter data. As a result, the clean-up ...   More
