Our Tools
Riverscapes Data Exchange
Store, curate, share and discover geospatial data related to rivers. The warehouse incorporates our WebRAVE interactive web mapping interface for viewing data without the need for desktop GIS software. A minimal metadata standard is all that is required to make data compatible with the warehouse.
GCD
The Geomorphic Change Detection (GCD) is an ArcGIS AddIn or standalone software for quantifying the difference between raster datasets while taking uncertainty into account. Originally designed for differences in Digital Elevation Models (DEM) the GCD can measure change between any two raster datasets.
Cross Section Viewer
Manage and visualize river transect data using a simple data model that accommodates most types of survey data. Interactive tools include areal, profile and longitudinal plots as well as several geomorphic calculations that would typically take a user a considerable amount of time to produce.
Habitat Suitability
Calculate habitat using either suitability curves or fuzzy inference system expert logic. Desktop software design for estimating fish suitability using pier reviewed curves and either geospatial or tabular data.
INSTAR
Geospatial database and laboratory software for tracking taxonomic identification of macro invertebrate organisms. Cloud-based, INSTAR provides a secure GraphQL API and R Package for data retrieval and analysis.
Topographic Toolbar
ArcGIS AddIn for processing high resolution topographic survey data. Includes features for survey data QC, local or projected coordinate systems and delineating streams with centerlines, cross sections and inundation polygons.
