GEDI Maps
Overview
At the core of our GEDI software, is a suite of spatial data visualisation and analysis tools.
The maps are presented using Scalable Vector Graphics (SVG). SVG is similar to XML and is a
web standard recommended by the W3C (World Wide Web Consortium)
for presenting both vector and raster information. SVG enables simple, attractive and accessible maps to be rendered.
Microsoft's Silverlight plugin will be supported in mid 2008.
Standard Features
Our SVG map interface supports industry standard tools for panning and zooming and general map navigation. It also includes tools to
copy the map to your computers clipboard, so that it can be pasted into other applications.
Other extremely useful tools that are included in GEDI are a distance measuring tool and facilities to help
with drawing your own points, lines and polygons.
Data Analysis Features
In addition, GEDI contains more powerful map based analytical tools. This includes
time series animations
and the ability to select map features that lie within a certain distance of other features (e.g. services within a ward), as shown below.
New Statistical Analytical Tools
GEDI now contains powerful analytical tools. Have a look at the demonstration
version at www.gedi.org.uk. The new tools enable users to
thoroughly analyse their data by choosing different types of ranges, numbers of intervals and colours.
GEDI supports a wide variety of statistical data. This data could be percentages, ratios, ranks or many other types of statistics.
Recently, support in GEDI has been extended for classed data. A good example of this data is shown in the GEDI demonstrator
and uses Output Area Classification data. This data, produced by the Office for
National Statistics, is freely available and classifies small area 2001 census data. It compares well with other classification
data, such as Experians' MOSAIC or CACIs' ACORN data which are also compatible with our GEDI systems.
