Zoom In Tool:

• Check the Zoom In radio button.There are three options for zooming in:
• Single click on the map. The map will first center at the click point, then zoom in. OR:
• Drag and draw a window on the map.  The map will zoom to the extent of the window. OR:
• Click the Zoom in link directly. The map will zoom in one level based on the existing center of the display:

Zoom Out Tool:

• Check the Zoom Out radio button.
• Single click on the map. The map will first center at the click point, then zoom out. OR:
• Drag and draw a window on the map.  The map will zoom out based on the ratio of size of the window and the map extent. OR:
• Click the Zoom out link directly. The map will zoom out one level based on the existing center.

Pan Tool:

There are two options for panning the map:

• Check the Pan button, then click on the map and hold the mouse button down. Drag the map in the direction that you want to move it and let go of the mouse button.
• Click on one of the eight arrows (  ) that surround the map to pan the map in the direction that the arrow points.

Identify Tool:

• Check the Identify radio button.
• Click on the map at the place you want to get information. The information will be displayed in a separate “Identify Results” window that will pop open. Several layers (i.e. Parcel, Land Use) are pre-configured for their information to be displayed in the window.  If you want information from other layers to be displayed in the “Identify Results” window, click on the LAYER CONTROL link on the base map page. Iin the “Layer Control” window check the boxes in the “Identify” column for the layers you would like to display information.

Zoom to a pre-defined level:

By clicking on one of the links under the map, you can zoom to a specific pre-defined level, ranging from parcel to citywide. The initial extent of the map is the citywide level.  The lower the number the closer the zoom level.

Check the boxes to turn the layers on/off, labels on/off, or use the layer with the identify tool (see above). Layer names that appear in gray mean the layer is not visible at the current scale. Click or to change the scale and make the layer visible. Once the scale is changed, you may control the visiblility of the layer, etc. If a layer name has a hyperlink, it means that you may change the rendering properties of the layer(color, size, etc) and create a Thematic Map of the layer.

A thematic map is a map that depicts selected kinds of information related to a specific theme such as census information.  A user can make a thematic map by clicking on the Thematic Map hyperlink above the map window or by clicking a hyperlink of a layer name in the Layer / Legend Control window.

A new window will be displayed with a series of drop down boxes that will help setup the map. There are thress possible ways to render the map: Simple (draw all features same way), Graduated Renderer (classify the symbol based on a numerical field of the layer), and Unique (draw a feature base on the value of a field). For a graduated renderer there are three possible classfication methods: equal interval, quantile classification, and user defined. The user can also set the style and color of the symbols.

• Rendering Layer: this is the layer that will provide the data for the thematic map.
• Draw Features Using: this refers to the type of renderer used to make the map (see above)
• The remainder of the choices are based on the type of renederer chosen and are primarily for choosing the style, color and symbols to use in the map.

Clicking "default renderer" will restore the original renderer defined in the server.

For performance considerations, no moret than 5000 records will be retrieved for the graduated renderer or unique value renderer.

To find a specific address on the map you can use the Locate Address link on the menu bar.  This function uses a process called geocoding which matches a location on the map with a specific address, however it does not always produce the most accurate results.  If your search returns no results you should consider using the Query Data Tool (see above).

• Geocode Layer: Use the drop down list to select a layer to search (the default is street).
• Street: Enter the address number, street name and type (i.e. 601 Lakeside Ave).  If you do not know the address number leave it blank.
• Cross Street: enter the nearest cross street only if you have not entered an address number (i.e. you just entered a street name)
