GIS Data Viewer

GIS Data Viewer is a comprehensive application we have developed recently using the latest in ArcGIS Server technology. This interactive mapping application gives you direct access to the most current GIS data the county has. It enables you to find information detailing a variety of features in Will County. There are more than 70 map layers available including various basemap, agriculture, land use, hydrology, and public safety layers as well as aerial imagery. For advanced users, there are many spatial analysis tools included for use in the application.

There are two versions of the application. HTML5 and Silverlight. Both versions are very alike in terms of content. However, HTML5 version works across most browsers such as, Chrome, Firefox, Internet Explorer, Safari, etc. Also, it works on any OS (Windows, iOS and Google) on any device (desktop computers, smart phones and tablets). There are some new & improved features on HTML 5 version, but some features are missing from the Silverlight Application. The HTML 5 version will be updated with more features in future additions. Here is a document that describes the various features of the applications and differences between the two versions. PDF - Differences between the GIS Data Viewer for Silverlight and HTML5
