In today’s and next week’s lab you will be working in ArcMap to produce a map of UNBC, using source data provided.
You will have today’s lab period as well as next week’s lab period to produce a pair of maps, designed for page size (8.5 x 11″), following cartographic principles taught in lectures.
- Symbolize all feature layers
- Label features (Shane Lake, University Way, Tyner Blvd, Greenway, UNBC)
- Locator Map
- Title, scale bar
- Appropriate Legend
- North Arrow
- Your Name and Date
The goal of today’s lab is to create the main map area and a locator map. Next week we will be adding ancillary information. It is up to you however, to make sure the map is completed by the end of next week.
Create a new folder and add the datasets:
- Login to a machine and start terminal server.
- Create a new lab folder lab4 under your geog205 folder.
- Start ArcMap and choose A new empty map
- Add all layers from: L:\labs\geog205\symbolization
- Save your map document as lab4.mxd in your local folder
Check the drawing order so that no features are hidden.
- Change Data Frame name from “Layers” to “UNBC” as follows: Click on the Data Frame name Layers so that it is highlighted. Click on top of the word “Layers” a second time and it will now be editable.
- Change the name to UNBC.
- Save the map file
Examine the attribute tables for each layer to see any additional values that may be used in the map. Here is an example:
In the layer FFW_points attribute table, there is a field called Type. This field gives the category for the points of interest.
Remember to employ the cartographic conventions discussed in lecture.
Symbolizing Polygon Features
Polygon feature classes can be symbolized with solid fills, outlines or patterned fills. They should not be overpowering (follow the methods explained in the lecture for polygon colouring (no bright red parking lots).
For example, for unbc_boundary
- Open its Symbol Selector (click the symbol in the Table of contents)
- Click the Hollow symbol from the list to remove the coloured fill. Note the symbol Preview upper-right.
- In the Symbol Selector click Edit Symbol
- Click Outline
- Choose a boundary line pattern from the samples available (you will revisit this layer later on)
- Click OK, OK, OK to close all symbol windows.
- Save your changes to the map document. Main Menu –> File -> Save or click the Save button.
Examine the Symbol Selector for lakes. Choose an appropriate symbol for lakes.
|Note the value for Outline Width. This is the thickness of the outline of lakes.To examine the colour values for the outline, click the outline colour patch (the outline color icon), then click More Colors. Change the colour model to HSV (click the black arrow for a selection of colour models). Write down the three numbers for Hue, Saturation and Value. You can use these values later for symbolizing creeks.|
Symbolizing Line Features
To symbolize creeks, we might wish to match the lakes outlines (although the creeks might be considered ‘ephemeral’, they also represent where gullies are (gullies are good indicators of topography).
|Note the colour model and values as seen for the lake outline:HSV206, 96, 96 (your values may be different)
Examine the Attribute Table for Roads. Symbolize roads by the surface categories and create a hierarchy for the road surfaces for paved, campus and gravel. You might keep roads as solid lines, but you may change the colour and width. To set up the hierarchy:
- Right click the roads layer and select properties
- Open the Symbology tab.
- Click on the Categories option (in the left hand pane) keeping Unique Values selected
- Select “Surface” from the Value Field drop down
- Click on the Add All Values tab
- Uncheck all “other other values”
- Set the line style for each type of road surface
See the reference illustration below to see the style by category process
Next, symbolize the trail layers. Examine the Attribute Tables for trails and greenway. Note the hierarchies: pathway and trail (a pathway is a wide trail that allows two people to walk together). The Greenway is a pathway type. Close all tables. Decide on an appropriate line pattern hierarchy to match these classes. Symbolize the trail layer as Categories using their Surface field. Tips on modifying a dashed line are described as follows:
|As well as changing the line thickness and colour of a patterned line, you may design your own pattern for a dashed line. You can set your own spacing for dashed lines by:
Previewing Your Work:
|The illustration at left has no reference scale. Zoom in closely on a selection of trails.You are not yet able to see the difference in your trail design.In order to see your line thickness you must set the Reference Scale.The Reference Scale is that display scale at which size and thicknesses display at their true values. With a defined reference scale, these true values are retained as display scale changes.|
- Data Frame -> Properties –> General Tab Change the Reference Scale to 1:25,000. OK
- Zoom in and out and note that your symbol sizes can now be seen, and remain relevant to the scale.
As you examine your map, you may find the patterned lines of the boundary clash with the patterned lines of the trails.
You can improve the distinctiveness of the unbc_boundary layer by changing its line style.
- Click the symbol for unbc_boundary and choose Hollow symbol (should already be set to hollow).
- Follow the same methods you used for the lakes to change the unbc_ boundary outline to the “Boundary State” symbol (you can search for the style directly and it is found under the ESRI symbol set) .
- You can change the color here too, then click OK and OK again. Now you can have a symbol as the following.
Symbolizing Point Features
Examine ffw_points – Type field (open the Attribute Table). You will see these values:
Picnic Shelter: Covered picnic tables.
Lookouts: A wooden viewing platform.
Water Tower: Location of water tower.
Marker Post: Distances to nearby features.
Height of Land : Covered picnic tables.
Bridge: A wooden viewing platform.
Garden: Location of water tower.
- In the point feature class Symbology tab, click Categories at left and Unique Values to display data based the unique values from attribute table.
- Select ‘Type’ field for Value Field. This is the field which all unique values are from.
- click Add All Values button
We only want to add to show some point locations on the map (Lookout, Water Tower, Picnic Shelter, and Marker Post). You will need to remove the rest of point lcoations from the map.
- Highlight Bridge and click the Remove button. Similarly remove the others
- Change the symbology for the points.
- Looking for more symbols? In the Symbol Selector, click the Style Reference button and activate any checkmark to add additional symbol sets .
- Choose an appropriate symbols for each point location
- Zoom to your reference scale, and pan around the map to evaluate the size of your point symbols.
- Save your changes. Main Menu –> File –>Save, or click the Save button.
Labeling can be done in both view modes: Data View and Layout View
Labeling in Data View: usually for labeling the features themselves (i.e. placing city or town names next to the layer’s points)
Labeling in Layout View: usually for adding ancillary information such title, creator, date, and other description
Ensure you have set your Reference Scale:
- Data Frame -> Properties –> General tab: Set the Reference Scale to 1:25,000
It is important to follow the labeling guidelines discussed in lettering lecture (note sections 6 and 7)
- Click Main Menu -> File -> Page Setup
- Set page Orientation to Landscape
- Remove the checkmark for Use Printer Paper Settings (this makes your map independent of your computer’s printer driver).
- Checkmark Scale Map Elements proportionally to changes in Page Size
- Click OK
- Zoom to Full Extent
- Save changes to the map document: Main Menu -> File -> Save
Set the Labeling environment by activating the “Drawing Panel”
Usually the Drawing toolbar is displayed at the bottom of the window.
- If it is not shown, Main Menu –> Customize –> Toolbars and ensure there is a checkmark for Draw.
Recall the cartographic convention for labeling water features. Make the necessary changes to the Font, Font size, Font Style and Font Colour in the toolbar to match the conventions (conventions not shown in example below):
Labeling Shane Lake
Let’s place a label for Shane Lake. Zoom in on Shane Lake in Forests for the World.
- Click the New Text tool and click a location inside the polygon for Shane Lake.
- A text box is shown there that allow you to enter text. Type Shane Lake and tap the Enter key to finish.
To make changes after you have added a piece of text, click the Select Elements tool and:
- Double click the text box Shane Lake. The properties window pops up.
- Click the Text tab, here you can change the text. Move your mouse cursor right before Lake and hit Enter. This will move the text ‘Lake’ to the second line as putting all text in one line cause part of text outside the Shane Lake boundary. You can also change the text justification to centre.
- You can change the font type, size, colour, style etc. if required.
- Click OK and click OK again. The text should be displayed in two lines.
- Using the Select Elements tool select the Shane Lake text. Move it to make the text better fit inside the lake.
Next, you will create labels for roads. Change the font, font style, font size and font colour to appropriate values.
You can use New Splined Text tool on the Drawing tool bar to place curved text along a feature. To label University Way and Tyner Blvd:
- Click the dropdown arrow beside Text Button on the Drawing Toolbar and choose Splined Text tool . This tool allows you to place a text along a curved or angled linear feature.
- First you will draw a line to parallel University Way. This is the line the text will follow.
- A text box is shown to allow you to type in the text. Type in University Way in the text box and hit Enter. The text will be placed along the line you just drew.
- Next, label Tyner Blvd which is the road starting from the university loop towards College Heights.
You should label:
- The greenway trail as Greenway
- Shane Lake as Shane Lake
- University Way for the road from 15th Ave to UNBC
- Tyner Blvd for the road from UNBC to College Heights
- Forests for the World
- UNBC Reserve Land
- Change to Layout View: Main Menu -> View -> Layout View . You are now examining the page. Using the Select Elements tool, move and re-size the UNBC Data Frame as required.
- Insert a second Data Frame as follows: Main Menu –> Insert –> Data Frame
- In the Table of Contents, change the New Data Frame’s name to Locator Map.
Use the Select Elements tool to move and re-size the Locator Map Data Frame as required. With the new data frame selected, you will now add the outline of Prince George, as well as the major rivers found in the NTDB lakes layer:
- Add Data L:\labs\geog205\symbolization\locator\ntdb_lakes.shp as well as pg_bound.shp
- Alter the symbology for these two layers to reflect the mapping conventions discussed in the lecture .
- Adjust the extent and shape of the Locator Map Data Frame so that the outline of Prince George (pg_bound layer) fills the frame.
- Save your changes to the Map Document.
Next, you will link the two data frames so that the outline of your map of the UNBC Lands shows up in the Locator Map.
- Locator Map Data Frame –> Properties –> Extent Indicators tab.
- Under Other Data Frames select UBNC.
- Click the top arrow to move UNBC over to the list on the right.
To change the thickness and colour of the extent rectangle, click the Frame button on the Extent Rectangles tab (remember to select UNBC first – otherwise the Frame button is grayed out).
- Click the Apply button and examine your results.
- Save your changes to the Map Document.
- Set the Reference Scale for the Locator Map Data Frame to its display scale.
|You can label map features directly in the Layout View. If you are labelling map features, you must make the data frame the focus as follows:Right-click the Locator Map Data Frame on the Layout Page. From its pop-up menu, click Focus Data Frame.Why do this? You would like the labels Map Extent, and Prince George to have real-world coordinates that tie the labels directly to their respective map features.If a data frame is not the focus, then any text you add in the Layout View are given page coordinates.In the Locator Map at left labels were added using the Draw toolbar New Text button. Add these labels now (see the image at left)|
- Save your changes once last time Main Menu -> File->Save to save the map into file lab4.mdx
- Save again as lab4bw.mxd and modify design for black and white – see Lab assigment #1 below
(You could also start the monochrome version from scratch, but then you’d need to repeat the lettering)
If time permits, you can proceed to next week’s lab with your remaining lab time for this week (see below first)
- Quit from ArcMap
- Click Start -> Logoff Click Log Off to logout from terminal server
- Click the first icons on the menu bar located at bottom and choose Logout to logout Linux.
The first lab assignment is to produce two finished maps (8.5 x 11″), through labs 4 and 5.
This assignment is due Monday 4pm, February 13th
- with free use of colour design as in lab instructions
- in monochrome (colour not allowed) – as if to be printed in a book or newspaper
NOTE: You are welcome to make two indivdual maps – or one map that can be printed in both colour and in monochrome. We would suggest making one versitle map…
- Create a new point layer (you may call it peak.shp) and add the highest point of PG at 510050, 5971300 to this dataset.
- Merge the greenway trails to trails to make them in one trail layer.
- Symbolize peak and trails
Evaluation for the assignment
This assignment is worth 10% of the overall class grade. This 10% is broken into:
- 5% for the symbolization of the maps
- 5% for the overall layouts (may be mostly similar for the two maps).
Ensure that in both cases, your symbolization follows cartographic rules, and sufficient contrast enables the distinction of all symbols. This may be more challenging for the monochrome map (as you discovered from the lab today). For this reason, you should exclude the creeks from the second map.
- Create a folder in your geog205 directory called assignment1
- You would next save your colour map as lab4_colour.mxd and again as lab4bw.mxd and then modify its design for black and white. These files should be saved in the assignment1 folder
- Finally, save your map as PDF version (described in lab 5) in the same folder
- Print out colour map and black white map respectively. Staple them together and hand it in to your TA or Drop-Off box 2O at the second floor of Teaching lab building (building 8)
