The ESRI ArcReader 9x control allows for embedding maps within custom applications and databases to enhance the capabilities of ESRI Published Maps and to link these seamlessly with tabular data.

Since the release of ArcGIS 9x the ArcReader control has been modified to allow for royalty free distribution of map enabled databases and applications. We have used this on a number of projects ranging from VB.NET applications with custom hyperlinking capabilities through to MSAccess databases that allow for dynamic map updating. Users can query their database via conventional database searches or by clicking on the map and can update their map display dynamically via the selection of key parameters from drop down database lists. By trapping user interaction with the map custom code can be run to further enhance the built in capabilities of Published Maps.

The simple marriage of maps and database forms allows users to have seamless access to tabular data from a mapping interface and the royalty free distribution of the ArcReader control allows for rich solutions to be offered to clients without the need for costly software licences.

A recent project focussing on establishing a Water Quality Objectives and Targets Inventory shows dynamic interaction of the inventory data with a simple embedded map covering the Murray Darling Basin Region.

The ArcReader control may not be an alternative for many GIS solutions however it does allow GIS professionals to provide end users and clients with simple tools that present their data in a meaningful and focused context.
