Data Retrieval and Graphing Using the LTRM Fish Catch GeoJSON Data Service

UMESC hosts a web service for the retrieval of LTRM fish catch data using the GeoJSON data format. By using this data service, the public can automate data access to LTRM fisheries data. UMESC has written a series of example Python scripts that illustrate data retrieval and plotting. These example scripts focus on plotting fish catch, but there are limitless geo-spatial, tabular, and plotting pr

WellFootprint Software Release

The WellFootprint software is used to generate a 'footprint' of well withdrawals that can better communicate the distribution of well withdrawals. The compiled program, source code, documentation, and an example are included.

SAS code for analyzing water temperature data

This code may be used to fit linear models with multivariate random effects and heterogeneous measurement-level residual variances. The code as written may be used to estimate associations between water temperature ('temp') and continuous year ('yearctr'), study reach (or field station; 'fs'), log-transformed mean July water discharge (in 1000 cms units; 'logmeanJulycms1000'), number of days from

Symbol Tweaker Tool

Symbol Tweaker is an ArcGIS ArcMap add-in tool developed at the UMESC. When using this tool, a user can: 1) Adjust RGB or HSV parameters of selected symbols from feature and raster data layers 2) Create unique color ramps for feature and raster data layers 3) Copy fore, back, and outline colors interchangeably 4) Create equal interval classifications beyond the limitations imposed by ArcMap

National Water-Quality Assessment (NAWQA) Area-Characterization Toolbox

By Curtis V. Price, Naomi Nakagaki, and Kerie J. Hitt

Montana StreamStats: a water-resources web application

StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.

SeismoTectonic Regime Earthquake Calculator (STREC)

Automatically determines the earthquake type (subduction zone interface, active crustal shallow, stable continental region, etc.) and the earthquake focal mechanism.

Composite Raster and Divergence Tool

ArcGIS ArcMap add-in, when using this tool, a user can: 1) create a date prioritized composite raster from a collection of raster layers 2) create a lookup raster for the composite raster that identifies which input layers were used to create the composite raster 3) create a divergence raster where pixel values represent the divergence from a user specified value

Composite Raster and Divergence Tool

The Composite Raster and Divergence Tool is an ArcGIS ArcMap add-in

SPARROW modeling: Estimating contaminant transport

SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources.

Chemical Mixtures Software

The chemical mixtures software is a collection of computer programs for investigating the composition, occurrence, distribution, and potential toxicity of chemical mixtures.  The software is designed to assist with selecting specific mixtures for future research, identifying the causes for the occurrence of specific mixtures, and discovering the effects of mixtures.
