Geospatial Sciences and Technology
The Geospatial Sciences and Technology (GST) program focuses its efforts on providing technical and data development assistance to UMESC and its program partners. The GST teams specialize in; using geospatial (location referenced) and remote sensing technology to collect, create, and analyze geospatial data; and creating decision support tools that make geospatial data and technology more accessible to resource managers and researchers.
A Decision Support System (DSS) can be defined in many ways. The working definition the Upper Midwest Environmental Sciences Center (UMESC) uses is, "A spatially based computer application or data that assists a researcher or manager in making decisions." This is quite a broad definition and it needs...
The ability to predict the distribution of submersed aquatic vegetation in the Upper Mississippi River on the basis of physical or chemical variables is useful to resource managers. Wildlife managers have a keen interest in advanced estimates of food quantity such as American wildcelery (Vallisneria americana) population status to give out more informed advisories to hunters before the fall...
- 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 ...
- 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 ...
- The Census Stop Tool is a GIS tool that creates random points along a line layer while maintaining a minimum distance between points.
- The user has the option of selecting one of two random point placement methods.
- The Census Stop Tool is available as an ArcMap 9.x extension.
- This tool is designed to facilitate road based surveys by reducing the potential for ...
- The Adjacency For WinBUGS Tool is a customization of ArcMap.
- The tool iteratively processes each polygon within a selected layer and creates a text file of polygonal adjacency where each polygon is identified by a unique Adj_ID value.
- The output of this tool is used in WinBUGS (MRC Biostatistics Unit Cambridge) by the car.normal, car.l1, and mv.car conditional ...
- The Percent Edge Tool is a customization of ArcMap that analyzes polygonal shapefiles.
- The Percent Edge Tool calculates 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.
Example query: I want to know where are all of the large, ...
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.
Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine
Most national parks interact with adjacent lands because their boundaries fail to encompass all regional habitats, species pools, and migration routes. Activities planned for adjacent lands can have adverse effects on park resources and visitor experiences. For example, fragmentation of adjacent habitat into smaller and more isolated remnants may influence the suitability of park habitat for a...
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 ...
Application of Wind Fetch and Wave Models for Habitat Rehabilitation and Enhancement Projects - 2012 Update
- Models based upon coastal engineering equations have been developed to quantify wind fetch length and several physical wave characteristics including significant height, length, peak period, maximum orbital velocity, and shear stress
- These models, modified to operate using Environmental Systems Research Institute's ArcGIS 10.0/10.1 Geographic Information System platform, were ...
There are ongoing needs for analytical tools to investigate the cumulative effects of fluctuating water flow and depth. The Connectivity and Inundation Tool was developed at UMESC to help address these needs. The tool allows for the investigation of the historic hydrographs or proposed theoretical hydrographs. It does this by utilizing existing 2D hydrodynamic models that have been...
