.. a Visual Data Analytics (VDA) Geographic Information Systems (GIS) tool .. embedded in HTML iframe for interactive use in Web pages A Geographic Information System (GIS) is a computer -based tool that allows users to store, analyze, visualize, and interpret geographic data. Geographic data, also known as spatial or geospatial data, identifies the location of features on earth. GIS combines the visual elements of maps with the ability to link characteristics about those features in datasets. This relationship allows GIS to locate, display, analyze, and model data. GIS technology integrates geographic data with statistical and adminstrative data using statistical methods and analytics. These abilities make GIS valuable to a wide range of public and private enterprises for explaining events, predicting outcomes and planning strategies. And collaborating on those issues. iVDA is an HTML iframe embedded version of VDA Web GIS Verison 4. iVDA can operate with any VDAGIS project.
