In-class map excercise showing crime rate per 1,000 for towns in Middlesex County.
The directions below are also
available here as a Word doc that you can print out.
We are not going to include info on police pay or name the towns on the
compilation copy.
Download this
pdf file of towns in Middlesex County to your U drive space (right click; save link as).
Use Adobe Illustrator to open this file. This will serve as the base for your map of crime in Middlesex County.
This would be a good time to "save as" and name your file.
Make sure it is in your U drive space. Save often.
You will see that the bottom layer in the file is a screen capture of the area from Google maps.
This is only meant to serve as a reference to help you locate the 25 towns in Middlesex County and to create a scale bar.
You should click off the "eyball" for the bottom layer so it does not print out on the map you hand in.
Create a new layer for each class you will be creating, and name it with the range of values of the class interval.
For example if you divided the data into three classes, create three new layers.
Next, follow the directions below to move each town to the appropriate layer based on the class you assigned it to.
Make sure the Layers Palette is open and visible. It may not be open, or it may be in the dock.
You can open the Window menu at the top of the screen to see which palettes have a check mark next to them.
If there is a check mark next to Layers, it is open, though may be out of site in the dock on the right side.
Put you cursor over the dock and it will give you the name of the palette. If it is what you want, click to open it.
If there is no check in the Windows menu next to a palette you want, click on its name and it will open.
The 25 town polygons are filled with white to help you select them.
Use the black arrow and click anywhere within the polygon to select it.
When the polygon is selected, a colored square representing it will show up in the town polygons layer.
Drag that square up to the layer you want to move the town polygon to, and release (this is how to move objects to another layer).
The polygon should still be selected, and the square in the
Layers palette will change to the color of the new layer.
Repeat this procedure until you have all of the 25 towns divided into the classes that you created.
This should leave the town polygon layer empty. To check, click on the circle icon on the town polygonlayer in the
Layers palette.
Clicking on the circle icon (toward the right side of a layer) selects everything on that layer.
If the layer has been emptied correctly to other layers, nothing will be selected. If it is empty, you can delete it.
The same technique can be used to add shading to every polygon in a class (one layer at a time).
In the Layers palette, click on the circle icon of your lowest class layer to select every town polygon on that layer.
With all the towns in the class selected, pull down the fill menu and select a light gray shading for them. Repeat these stips for the other classes.
The lowest class will have the lightest shading, the highest class interval range will have the darkest gray.
