Below is a graphic that shows what the main DemographicMapper page will look like when you enter. Key features of the page are labeled in this graphic and are described below.

This main portion of the screen is where you view the map that meets the specifications you have ordered. As you pass the mouse over the Map Display, the coordinates of the cursor point are displayed in the statusbar at the bottom of your browser window. These coordinates correspond to the NAD83 Virginia State Plane coordinate system and are in units of feet. In the lower right of the Map Display is a scale bar which indicates the scale of the returned map in feet.

The small locator map provides a point of reference for the current map view. Even though the current map view may be zoomed in to a single parcel of land, the location map will always indicate where in the County the current map view is located.

Different types of geographic data are called "layers." The Layer List lists all of the layers that may be viewed on the map. Any number of layers may be viewed at one time, depending on the zoom level in the current map view. The Layer List contains options for turning layers on and off as well as labeling and identifying/selecting the features in a layer. Changes made in the Layer List must be submitted to the application by pressing the Apply Changes button. A more detailed description of the Layer List and its functions is provided in the detailed function descriptions section.

Many of the basic functions needed to navigate around or interact with the County's geographic data are located above the Map Display in the Toolbar. These tool functions allow you to zoom in, zoom out, and pan (i.e., recenter) the map view as well as identify or select map features, create thematic maps or create a print preview page. Each of these functions is explained in greater detail in the detailed function descriptions section.

The DemographicMapper also contains many useful search tools which can be found in a drop-down box to the right of the Map Display. These functions allow you to quickly locate features on the map by entering search criteria or by selecting from a predefined list of features. Examples of the available functions are: Locate a Parcel by entering an address or Grid Parcel Identification Number (GPIN), or Locate a Census Tract. All of the Search Functions are explained in greater detail in the detailed function descriptions section.

This area to the right of the Map Display is used to gather information from or return information to the user. If you identify or select map features it is in the Results/Report Area that the data will be returned. When using the Search Functions that require entry of search criteria, it is in this area that you will be prompted for input. The Results/Report Area is also used to prompt you for more input with some of the Toolbar tools, such as the Create Thematic Demographic Map, Select by Line or Polygon and the Print Preview tools.

These tabs allow the user to switch between interactive mapping applications. If viewing the DemographicMapper and you click the CountyMapper tab, the CountyMapper viewer will open replacing the DemographicMapper. Your map extent and layer selections will be preserved for ease of interoperability, however any selections will be lost.
