Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine
In this study, we examined habitat fragmentation consequences owing to a planned 1,295 hectare development by Winter Harbor Holding Company (WHHC) adjacent to the Schoodic District of Acadia National Park (ANP), Maine.
Curve Fit: A Pixel Level Raster Regression Tool
Curve Fit is an ArcMap 10.1 (10.2 forthcoming) tool that:
- performs pixel level regression analysis on a series of raster datasets
- is capable of calculating both linear and nonlinear regressions
- allows the user to constrain parameters for nonlinear models
- generates raster surfaces representing parameter estimate, model fit, and multi-model inference ...
Percent Edge Tool
The Percent Edge Tool is an ArcMap tool. The Percent Edge Tool performs the following calculations for each polygon in a polygonal GIS layer: area, compactness, perimeter, edge lengths with adjacent polygons, and percentage of edge with adjacent polygons. This information can then be summarized into a pivot table and queried.
A Tool for Prioritizing Management Units at Morris Wetland Management District
Where are most important places to direct conservation effort? Such a simple question is not answered simply. There are a myriad of priorities, constraints, and capacities, both scientific and socio-economic, which in combination guide the allocation of management effort. An honest accounting of these priorities, constraints, and capacities is essential for efficient, effective action.
LINK: ArcGIS Tools for Conservation Planning
- Allows managers and planners to rapidly assess landscape attributes and link these attributes with species/habitat information
- Provides resource managers a means to compare the conservation potential of local management units with that of the surrounding county, state, or region
- Can be applied to any taxa or suite of taxa and any landscape, given that spatial data. ...
Split By Attribute Tool
- The Split By Attribute Tool is a customization of ArcMap.
- The tool takes a single shapefile and splits it into many shapefiles based on the unique values of a chosen field.
- If the user has made a selection on a shapefile, then only those features that have been selected will be split.
- Each output layer will named with the following structure: user supplied base ...
Spatial Data Query Tool - Upper Mississippi River
The Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has collected millions of records of information over 20+ years. Fisheries, water quality, vegetation, and invertebrates have all been sampled. Geographic locations were collected for all sampling points.
Streamflow Observation Points in the Pacific Northwest, 1977-2016
This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.
Evapotranspiration units and potential areas of groundwater discharge delineated July 20–24, 2009 in the upper Humboldt River Basin, northeastern Nevada
The data set consists of 2 separate items for the upper Humboldt River Basin:
1. evapotranspiration units
2. potential areas of groundwater discharge
Groundwater-level and groundwater-level change contours for the Lahontan Valley shallow aquifer near Fallon, Nevada, 2012
One dataset contains contours representing water levels based on depth-to-groundwater measurements made at 98 wells in July 2012 in the Lahontan Valley. The second dataset contains contours representing water level change in the shallow aquifer in Lahontan Valley from 1992-2012 based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013...
