Use the Map Milwaukee Tutorial, developed by the City of Milwaukee Training and Development Services, Department of Employee Relations. This tutorial is a useful tool for learning how to use Map Milwaukee, or to learn some new tips and tricks for the experienced user.
Map Layer Visibility
When you first start Map Milwaukee, the frame to the right of the map frame displays the Layer List. This lists each piece of map data available to you.
To the left of each layer in the list is a check box and a radio button. The check box determines whether that layer is visible on the map. To make a layer visible, make sure there is a check in the corresponding visibility checkbox and click the Redraw Map button at the top or bottom of the Layer List frame. To make a layer invisible, or turn it off, uncheck the visibility checkbox next to the desired layer and then click the Redraw Map button.
A Few Notes Regarding Visibility
1. Layers are drawn on the screen in order from bottom to top of the Layer List. For example, if you make both the Quarter Sections and Zip Codes visible, your map will look like the zip code polygons are laying on top of the quarter section squares. Therefore, you will only be able to see the parts of the quarter sections that extend beyond the zip code boundaries. It is important to remember this when displaying more than one polygon layer at one time - the polygons of the "top" layer may be covering up polygons of another layer that is listed below it in the layer list.
2. Some map layers, like parcels, have scale-dependent visibility parameters. For example, even if you have the visibility checked for parcels, you will not be able to see them until you zoom in far enough. Other layers, like zoning, have scale-dependent labels - you can see the polygons when zoomed to the entire city, but as you zoom in, zoning labels will appear. This is done for better map readability and faster display when drawing layers with large amounts of data.
The Active Layer
The round radio buttons next to layers in the Layer List indicates whether or not a layer is active. Only one layer can be active at a time. Some layers do not have the option of being made active. Parcels are the active layer by default. By making a layer active, you are telling Map Milwaukee which layer you are referring to when using the data tools: Identify, Query and Search.
Buttons and Tools
1. Click once on the map at the center of the area which you would like to enlarge. The map will then zoom in a standard amount using your click point as the center of the updated map. Continue to click on the map until you have zoomed into the desired scale.
2. In the map window, click and hold down your mouse button. With the button pressed, move your mouse to drag a box around the extent you would like displayed. Release the mouse button to refresh the map to this extent.
1. Click once on the map at the center of the area from which you would like to zoom out. The map will then zoom out a standard amount using your click point as the center of the updated map. Continue to click on the map until you have zoomed out to the desired scale.
2. In the map window, click and hold down your mouse button. With the button pressed, move your mouse to drag a box on the map. Release the mouse button to refresh the map to the new extent.
Unless you are familiar with the attribute data for the layer you wish to query, you will first want to use the Identify tool to become familiar with the available data. The columns listed in the identify are all valid fields on which you can query.
Now it's time to start our query.
1. Click the Query button and make sure the Parcels layer is active. In the frame below the map, the query form appears.
2.From the Field drop-down list, select Aldermanic District.
3.Make sure the Operator drop-down selection is =.
4.In the Value text box, type 16.
5.Whithin the query frame, scroll down and press the Add to Query String button. Now you see the first part of your query - the part that will find parcels in Aldermanic District 16.
6.Now press the And button (located in the top half of the Query frame to the right of the Value text box). This adds the word "AND" to your query string. The word "AND" links the two halves of your query string and indicated you want to find features that meet all parts of your query. In our example, we want to find parcels that are in Aldermanic District 16 and are owner occupied. Had we selected the Not button, we would find parcels that are in Aldermanic District 16 and NOT owner occupied. Had we selected the Or button, we would find parcels that are in Aldermanic District 16 OR are owner occupied (Or finds features that meet either/or both criteria).
7. Now select Owner Occupied? from the Field drop-down menu.
8. Make sure the Operator is still set to =.
9. In the Value textbox, type "O", including the quotes. (O indicates owner-occupied, N indicates not owner occupied). You can also press the Get Samples button to display a sample of the available options).
10. Click the Add to Query String button to add the second half of your query.
11. Click the Execute button.
Parcels that meet your query criteria will be displayed as a table in the frame below the map window and also highlighted on the map. If only one feature is selected, the map will automatically zoom to that feature. To zoom to one of many selected features, click on the number in the Rec field of your desired feature. If more than 25 features are selected, only the first 25 records will be displayed in the data table. To view more records, scroll down to the bottom of the data table and click the More Records link.
In the Street text box, type the desired address in all CAPS in the following format:
Street: N WATER ST
Click again to mark the end of your measurement segment. You will see a line has been drawn on the map and the distance between the two click points is displayed in the Total measurement box. Continue to click points to add to your total distance.
If you need to zoom in, out, or pan your map, your measurement information will be saved and you can continue with your measurement even if you no longer see the last click point.
To start a new measurement, click the Clear button.
