Pulldown menu and a

different line weight to see

how it looks. Finally

choose River as your symbol

Now do the same for the mj_lakes and lakes layers and choose the Lake symbol

Then Click ok and then ok again

Click the Weight Ranking button to open the

Weight Ranking screenUse Feature weights to control where labels are placed. Try different numbers in the feature weight column to see what the results are. By changing the numbers you can control which features have a higher importance for labeling features.For example if you make mj_lakes and lakes 100 the point symbols will not draw through any of the lakes unless there is no other option.

Map LayoutClick on the map layout button on the bottom of the ArcMap screen

It will bring you to the map layout page as shown below

Click on the data frame so it can be resized. Pull the middle anchor on the bottom of the page up to resize the map.

Move the map down a bit. The page should look something like this so a legend and title can be inserted.

Now we will add surround information to the map. By clicking insert along the top bar of ArcMap you can add a Title, Legend, North Arrow and Scale Bar by clicking each element that is required.

Insert the coordinate system information

Finally move the legend to the right side of the map layout. Move the other elements so it looks similar to the map below

The map can be exported To various formats such as

jpg, tif, pdf etc. Go to File atthe top of ArcMAP and

click export Map. Choose any format such as jpg or pdf.

If you wish to print the map you can go to File and click print

Quantitative MappingTo access the data go to C:\profiles\MDW600-LAB\My Documents\Exercises\Thematic. Open ArcMap and add the GTA shapefile to arcmap. Then add Toronto_data.dbf to ArcMap. This dbf file contains the attribute data that will be joined to the shapefile for mapping population by census tract in the Greater Toronto Area.

Right click on the GTA shapefile in the Table of Contents and open the attribute table.Then do the same for the Toronto_dat

Database.

Go to the attribute table and view the tables. Click on Table Options and then Arrange Tables and then New Horizontal Tab Group.

You will be able to view both

attribute tables at once

Next join the Toronto_dat table with the GTA attribute tableusing CTUID as the join field.

This will take the TOTAL_POPU

attributes and bring them into the

GTA shapefile attribute table.

Join the data by right clicking on GTA and then Joins and Relates and then Join.

Under Choose the field in this layer that the join will be based on, click on CTUID. That is the attribute from the shapefile GTA. Under Choose the field in the table to base the join on: CTUID from the toronto_dat table

Open the GTA attribute table with the joined data. Notice there are two CTUID columns. One with an asterisks * beside it.

Right click on the column CTUID * and clickTurn Field Off. This way only the columns you want to view in the new shapefile will show up.

Right click on GTA and export the data to a new shapefile by clicking Export Data

Call the new shapefile

GTA_join and click ok.

Then when prompted to add

the file to arcmap click yes.

Symbolize the MapDouble click on the shapefile GTA_join. The Layers Properties window will open. Click on the Symbology tab. Under Quantities choose Graduated Colors. Under Value choose TOTAL_POPU, this is the attribute value used to map the total population of each census tract. For Classes make it 6.

Now click under Range and change the first value to 0. Then in the second range type in 4500 then 6000, 9000, and finally 15000. The last one does not have to be changed. Under Label type 1 4,500 as shown below. Type the remaining labels as shown below. Click OK.
