With our focus on developing powerful human-centered methods and technologies that allow scientists and decision makers to use and analyze the growing wealth of geospatial data, we have created and developed a number of tools which are now available for your use.
GeoViz Toolkit is an application derived from GeoVISTA Studio in which a sample of Studio components were adapted to a more "user-friendly" environment and coordinated to support analysis of multivariate relationships in geographic space. Learn more at the GeoViz website
GeoVISTA Studio is an open software development environment designed for geospatial data. Studio allows users to quickly build applications for geocomputation and geographic visualization, with no programming required. Learn more at the Studio website.
The Visual Inquiry Toolkit (VIT) is based on the open-source Java framework GeoVISTA Studio, which provides a visual programming environment for spatial data analysis. VIT integrates visual, computational, and cartographic methods to enable human knowledge and judgment to be coupled productively with computational methods for incrementally searching patterns. Learn more at the VIT website.
GeoVISTA CrimeViz is a web-based map application for exploring spatio-temporal patterns of violent crime in the District of Columbia. Utilizing a suite of geovisual analytics tools, analysts can uncover detailed spatio-temporal patterns of DC crime. The client-server application plots up-todate crime incidents on a basemap using the Google Maps API for Adobe Flash. Learn more at the CrimeViz website.
SensePlace2 is a geovisual analytics application that forages place-time-attribute information from the Twitterverse and supports crisis management through visually-enabled sensemaking with the information derived. Visit the SensePlace2 website for more information.
HEALTH GeoJunction is a web application that supports scientists and other analysts in the task of quickly finding scientific research publications that are relevant not only to a particular topic, but also to particular places and times. Specifically, a visually-supported, facet-like filtering approach enables analysts to apply concept, place, and time filters on queries to PubMed results in an iterative fashion. The approach leverages visualization methods to help analysts develop potentially productive queries along with visual feedback about intermediate query results to support quick drill-down to documents of interest. A key feature of the approach is that analysts do not need to know all relevant query parameters prior to initial query formation. Try HEALTH GeoJunction.
SensePlace is a prototype web application that supports knowledge-enabled retrieval of news stories and other documents relevant to user-specified issues and places. It extracts and geo-tags references to places and enables situation assessment through web-map services that build a geo-historical context through which to interpret ongoing events. Try SensePlace.
The Geo-EXplication (G-EX) Portal is a web-based geocollaboration tool for the dissemination of geovisualization software and tools, learning artifacts supporting the use of these tools, and analysis artifacts generated during application of these tools. Learn more at the G-EX Portal website.
HerbariaViz is a web-based map that facilitates easy querying, displaying, and spatiotemporal exploration of a large plant sample collection (data provided by the Consortium of California Herbaria). Built with Flash ActionScript 3.0, HerbariaViz utilizes regional aggregation of point-based sample locations to expedite client-server transactions. Try HerbariaViz.
ConceptVISTA is an ontology creation and visualization tool that allows users to define and link concepts and resources pertaining to a conceptual domain. ConceptVISTA stores ontologies in the Web Ontology Language (OWL) format and can import outside ontologies. ConceptVISTA provides users with a useful set of ontology management functions. Learn more at the ConceptVISTA website.
The Pennsylvania Cancer Atlas and the National Cancer Atlas are highly interactive web-based, GIS-enabled cancer atlas prototypes, designed as a model for implementation of atlases to support government cancer control activities. The model integrates symbolization and design principles from print cartography, interaction strategies from exploratory geovisualization, and web-map/web-feature service advances from GIS.
Developed by the GeoVISTA Center in close cooperation with users at the National Cancer Institute, the ESTAT toolkit provides user-friendly, open-source software designed to support exploratory geographic visualization. While developed initially to support cancer research, ESTAT is designed to handle any kind of spatial data with attributes. Learn more at the ESTAT website.
ColorBrewer is an online tool designed to help people select good color schemes for maps and other graphics. ColorBrewer is free and easy to use - you'll be creating attractive color schemes appropriate to the nature of your data in seconds. Try ColorBrewer.
Improvise is a fully-implemented Java software architecture and user interface that enables users to build and browse highly-coordinated visualizations interactively. Visit the Improvise website.
These applets are demonstration versions of GeoVISTA Studio applications using U.S. Census data. Users can try their own data with the tools by accessing GeoVISTA Studio. Go to the Applet Gallery.
