MaDC©W is a Java applet created to display active, vector-based maps of various point, line, and polygon features and associated tabular data. One map page and zero or more table pages may be viewed for each project. The map may contain several layers of features downloaded from individual files (in non-proprietary ASCII or binary format for all feature types) or from an ODBC database (point feature types only). We're working on an ESRI shapefile option, which should be ready shortly. When project data is downloaded, all layers are visible and displayed at their full extent. The user may subsequently pan and zoom the map and hide or show feature layers as necessary. Then, at user request, tabular data associated with map features are retrieved dynamically from an ODBC data source.

If this is your first use of MaDC©W, please read the MaD Browser User's Guide for an introduction to its operation. The guide is only a few pages long and worth the look.

MaDC©W is a thick-client application that was developed as a data access tool to assist with toxic waste site remediation efforts. In these situations, it was expected that the number of features and attributes would be somewhat limited. You may expect MaDC©W to load slowly over slow Internet connections. (The ANL Demo Super-project offered below took three minutes over a 28k modem.) Once loaded, however, the applet seems to respond acceptably fast, even with data sets of several thousand items. If you have a slow connection, any of the following demonstration projects may be downloaded in two stages to ease the burden on your network and your patience. First call up the Empty Project below. This will retrieve the MaDC©W applet but no project data. Once the applet is running, click on the Load New Project button ("L" button) to download your choice of project data.

Empty Project: Loads the MaDC©W applet only. Project data can be loaded after MaDC©W is running. Useful for slow Internet connections.

ANL Demonstration Super-project: This is an super-project which serves as a visual map directory from which you may choose more detailed projects for downloading. These detailed projects contain on-site data on buildings, roads, monitoring wells, and related features at Argonne National Laboratory. Use the "INFO" button choice to inquire about and select detailed projects. The super-project data sets are somewhat large. This project may take a while to download on slower web connections.

ANL Project: This is all ANL offered as a regular project. Some of the same data layers displayed in the ANL super-project appear here as well, but there are additional layers included as well. This project may take a while to download on slower web connections.

ANL 317 Area: There are several study areas within or near ANL boundaries. Area 317 is one of them. This project includes a background aerial photo and a grid data layer.

ANL 319 Area: 319 Area project demonstrates security. Users must log in before they can download the project. The demo account is "test", the password is "test". In this demo, security is on the entire project. Security may alternatively be placed on individual layers if desired.

ANL 800 Area: Another study area. Nothing special here.

Freund Pond Area : Another study area. Nothing special here either.
