Instructions for Working with Delaware School Feeder and Legislative District Interactive Maps
This map can be broken into three separate sections. The first part (# 1 below) is the menu where you decide what you want to see on your map. This is done by clicking in the square boxes beside each menu item. The second part (# 2 below) is the actual map where the choices you make from the menu are displayed. The third part (# 3 below) contains a tool bar which allows you to search for active features, zoom in and out, identify items, etc.
Directions for selecting map layers (menu items) from section one.
To place items on your map simply check or uncheck the square box next to the item you want mapped. When the map first opens Towns and School Districts are already turned on by default. You can turn these two items off by un-checking them if desired.
Certain menu items cannot be checked while others are selected, and will reset menu items that are in conflict. For example checking All Public Schools will turn off any other school types selected above it (elementary, high, charter, etc.).
Some menu items are scale dependent and will not appear as choices until you are closely zoomed into an area on the map. For instance, City / Town always appears as a selectable map item; however as you continue to zoom into smaller areas, Highways and Roads also appear as a menu choice and are automatically turned on. They can be turned off by un-checking if desired.
Labels are also scale dependent. When viewing a map of the whole state few labels are shown. However as you zoom in closer, labels for selected items will begin to appear depending on how densely packed the items are in relation to one another.
Making a menu item Active by clicking on the round circle next to it (only one item can be active at a time) forces the tool bar to use the selected item for searches, queries, web links, etc.
Clicking the top left tool bar button switches between the Menu of items you can place on your map and the Legend for those items you have selected.
Directions for using the Tool Bar (section three).
A brief description of each Tool Bar button is provided below:
(See Tool Bar Examples Below)
1) How to Identify features on your map:
In this example we will use the identify tool to view the details of Delaware High Schools.
Click the square box next to High Schools in section 1 to see all the public high schools on your map, and check the round circle to make this layer Active in the Tool Bar.
Now click the Identify Tool Bar button to activate the Identify function. Move your mouse so that the crosshair + is on top of the school furthest north at the very top of the state and left mouse chick. At the bottom of your map you should now see the following information:
The high school furthest north in Delaware is Concord High School in the Brandywine School District. You can now left mouse click on any high school to see its name and school district.
Now make Cities / Towns the active layer by clicking on the round circle next to it in section 1. You can now click on any yellow area in the map to get the name and population of the town or city. The Identify Tool will work with every layer listed in section 1 if the round circle is checked next to it making it active. As you zoom in on an area using the Zoom In Tool Bar Button labels will automatically appear on your map for Visible Layers. Click the Zoom To Full Extent button to return to the full state view.
2) How to search for features on your map:
Searching for an elementary school
Click the square box next to Elementary Schools in section 1 to see all the elementary schools on your map, and check the round circle to make this layer active in the Tool Bar.
Now click the binoculars from the tool bar in section 3.
Next enter Milford into the box provided at the bottom of the page, and press Find String.
You should now see the following results at the bottom of your screen.
As you can see there are two Elementary Schools in Delaware with the word Milford in their address. To see Ross Elementary School click on the number 2 in the left column. The map will now zoom to Ross so that it is highlighted in blue and appears in the middle of your map. To un-highlight the school click the Clear Selections Button from the Tool Bar . Chick the square box next to Highways to have them appear on your map. Zoom in to a small area around Ross Elementary using the zoom button . You will now see all the roads around the school with their names. Un-click Roads and then Highways to remove them from your map, finally click the Zoom to Full Extent tool bar button to return the map to the full state view. If you had entered Ross instead of Milford into the find box above, the results would have only returned one school.
This same set of steps will allow you to search for Cities and Towns, Highways, Roads, School Districts, Private Schools and Day Care Centers. It is important to remember that a layer has to be Active (check the round circle) in order to search it for names. Lastly, if you do not find the item you are searching for, try again using less information (i.e. enter Cab instead of Cab Calloway School of The Arts).
