WISCOMP Viewer Instructions Page

The WISCOMP viewer uses ArcIMSŪ technology developed by ESRIŪ for displaying and interacting with a map. Users interact with the WISCOMP viewer through the use of Actions and Tools. Selections made in either the tool or action drop down list determine the method of map interaction. The tool and action drop down lists are located above the main map area in the WISCOMP viewer.

*Actions include functions that get performed with one click on the Perform Action button or functions that perform more complex tasks that require additional user input. Action buttons include powerful tools used to perform spatial analysis on both viewable information and the data that forms the map.

*Tools are functions that require the user to first click on the tool and then interact with the map in order to achieve a result.

Zoom in is the default tool when you start your session in WISCOMP viewer. You change your tool by selecting a new tool from the drop down box. Each one is described below. You can tell what tool is currently selected by looking at the status display in the upper left-hand corner of the page below the WISCOMP viewer Header.

Active Layer is the layer on which tools and actions work. To change the Active Layer, click on a layer name button in the Layer List. You can tell what Layer is currently active by looking at the 'Active Layer' status display located above the legend.


Remember: To perform an action, simply choose the action from the Actions drop down list and press the Perform Action button. The overview map in the upper left hand corner can be turned on or off by choosing Overview map on/off in the Action drop down list and pressing the Actions button. If you close or hide the Layer List, choose Rebuild layer list and press the Actions button to bring back the Layer List. Another way to bring back the Layer List if you have closed or hidden it is to click on the text above the legend that reads "Active Layer: ....."

Choose Full map extent and press the Actions button to show the full map extent in the map view.

Choose Zoom to Active layer and press the Perform Action button to show all features of the active layer in the map view.

The map will go to the previous map extent when you choose Back to Previous Extent and press the Actions button.

When you have made a selection on the map with one of the TOOLS, you can clear the selections by choosing Clear Selection and pressing the Actions button.

Query is the action used to find the location of features based on query restrictions put in by the user. The Query function operates on the Active Layer, so in order to search for Brownfields, the text in the upper right-hand corner must read Active Layer: Brownfields. To query, choose Query in the Action drop down list and press the Actions button. A separate window containing the Query function will open. First click on the 'Get Samples' button, this will access the database and allow access to current information. Then you can build your query to suit your needs by selecting a field and value from the lists. You may also place an operator on the value to find features with values that are equal to, greater than or less than the chosen value. Then click on the 'Add Query to String' button, which will place your query arguments in the bottom-most text box. You can repeat this process to add more arguments to your query. Finally click on the 'Execute' button. The results of your query will be displayed. For more information on this see our Query Instructions Page.

Buffer is used to highlight features in relation to other features. Buffer works on features of the Active Layer that are either chosen with the Select by Rectangle tool or that were displayed as a result of a query. While a feature or features are highlighted yellow, choose Buffer in the Action drop down list and press the Actions button. A separate window containing the Buffer function will open. You choose a layer to buffer your selection against and within what distance, check the 'Display Attributes' check box, then click on the 'Create Buffer' button. A graphic display of the buffer will appear on the map, and if you checked the 'Display Attributes' check box, a list of features within the buffer will also appear. For more information on this see our Buffer Instructions Page.

To view a printable page containing the main map, overview map, legend and title choose Print in the Action drop down list and press the Actions button. The system will prompt you for a title you wish to display. Enter a title or keep the default and click on the 'Create Print Page' button. A printable version of the map will then open in a new window. Use your browser's Print icon or go to File Print to print the page.


Zoom in is the default tool and is selected when WISCOMP viewer loads. To activate a new tool, simply choose that tool in the Tool Drop Down list.

With the Zoom In tool selected, you can zoom in by clicking a spot or by drawing a box on the map.

With the Zoom Out tool selected, you can zoom out by clicking on the map.

With the Pan tool selected, you can grab the map and drag it to a new position.

With the Identify tool selected, you can identify characteristics of features in the Active Layer. Just click on a feature you're interested in and any available information will be displayed.

With the Select by Rectangle tool selected, you can highlight features of the Active Layer. You can then perform ACTIONS on the highlighted features.

With the Printable Site Page tool selected and Brownfields as the Active Layer, you can click on any brownfield and a printable site description will open in a new window.


The Layer List window allows the user some control for changing the visibility of listed layers and for changing the active layer for map functions. Layers are set to visible, or 'on', when the Visible check box next to the layer button is checked. Layers are 'off' when the box is not checked. If you turn a layer 'on or off' you must press the 'Refresh Map' button for changes to take affect. Users can change the active layer for map functions by simply clicking the button with the layer name. The new active layer is shown in the 'Active Layer' status above the Legend.
