gis mapping
Much of the work that we do is best accompanied by a map. GIS services that we offer include:
- Current Use Assessments
- Forest Stewardship Plans and Plan Updates
- Timber Harvests and NHDES Forestry Notifications
- Property Line Mapping
- Conservation Land Mapping for Land Trust Organizations
The maps we create contain many layers of data about each property.
Depending on the property and the project, this data may include:
- Aerial photos, USGS topographic maps, USDA soils data
- Property boundaries & acreages, buildings, roads
- Cultural features, including stone walls and cellar holes
- Wetlands, perennial streams, brooks, vernal pools
- Forest stand types
- Log landings, access roads, skid trails
- Recreational trails, views, other unique features
- Ridges, cliffs, ledges, rocky outcrops
Note (FYI): GIS, or Geographic Information System, is a way to store, manage, and view data with geographic attributes. Essentially, it is a computer program that can be used to create databases and geographically accurate maps using a variety of sources for data input. For example, GPS coordinates of property markers taken on the ground can be uploaded onto satellite imagery, locating exact property boundaries on top of an aerial photographic background. From here, many different layers of geographically-referenced information can be added, including topographic maps, US Department of Agriculture (USDA) soils data, and other mapped features such as roads, streams, and wetlands. What isn’t included in these datasets can often be inferred from photointerpretation of satellite imagery. For example, forest type changes and even stone walls are often discernible from aerial photographs.
