Step 3: Adding Map Elements • Map elements • Map body—the primary mapped area. You can display more than one image of your primary mapped area within your document. For example, you may want to portray change by showing several images with differing but related information, such as population maps of various years. Your map may also contain a locator map (a smaller-scale map used to help the reader in understanding where the main area of interest is located), an inset map (used to give more detailed information of an area within the main map that may not easily be understood), or an index map (often used to show where in a series of maps one map exists). All are used to assist in communicating your information to others. In ArcMap, each of these mapped areas is referred to as a data frame. • Title—used to tell the reader what the map represents. This is often placed on a map layout as text. • Legend—lists the symbology used within the map and what it represents. This can be created using the Legend Wizard in the layout and edited further once created. • Scale—provides readers with the information they need to determine distance. A map scale is a ratio, where one unit on the map represents some multiple of that value in the real world. It can be numeric (1:10,000), graphic (a scale bar), or verbal (one inch equals 10,000 inches). Maps are often referred to as “large” or “small” scale. This “size” reference refers to the ratio (or fraction). For example, a 1:100 scale map is larger than a 1:10,000 map, because 1/100 (0.01) is a larger value than 1/10,000 (0.00001). A smaller scale map displays a larger area, but with less detail. The scale is inserted in the map layout view. • Projection—a mathematical formula that transforms feature locations from the earth's curved surface to a map's flat surface. Projections can cause distortions in distance, area, shape, and direction; no projection can avoid some distortion. Therefore, the projection type is often placed on the map to help readers determine the accuracy of the measurement information they get from the map. • Direction—is shown using a North arrow. A map may show true north and magnetic north. This element is inserted in the map layout view. • Data source—the bibliographic information for the data used to develop the map. • Other map components include (but are not limited to) dates, pictures, graticules or grids, reports, tables, additional text, neatlines, and authorship. Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
For your map you will be adding north arrow, scale bar, scale text, legend and a title. • Click on the Insert drop down and select Legend… this will bring up the Legend Wizard • Do not include the Quad layer in the legend • Remove all of the tif items listed under Legend Items column by selecting them and then clicking on the icon to move them back to the Map Layers: column • Click Next • Take the defaults for the next window – click Next • Use the drop-down from the Border menu and select 2.0 Point • For a Background color select Grey 10% • For a Drop Shadow color select Grey 30% • Click Next • For Legend Items make sure that PermitmineXYZ is selected • Click on the Area: drop-downand select the Urbanized Area shape • Click Next • Take the defaults for the spacing window and click Finish Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
The legend will appear in the center of your layout. Click and resize/move it so that your map looks similar to the one below: • Save your layout changes – Click on File > Save this will update your mapex9.mxd file • To insert a north arrow – Click on Insert > North Arrow… • In the North Arrow Selector window select the ESRI North 7 style • Click on OK • The north arrow will appear in the center of your layout. Click and resize/move it so that your map looks similar to the one below: Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
To insert a title for the map – click Insert > Title - this inserts a textbox with the default name that is the same as your .mxd file name (in your case mapex9) • Type in the text for the title - for your map type MineXYZ Stream Monitoring Stations • Move the title to a location on top of the map • Right-click on the title and select Properties • In the Properties window select Change Symbol… • Under Options Color: select a medium blue color • For Size: select 28 and turn on the bold option by depressing the B icon • Click OK twice to dismiss the windows and apply your changes Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
Click and resize/move your title so that your map looks similar to the one below: • To add a scale bar – click on Insert > Scale Bar… • In the Scale Bar Selector window select the Alternating Scale Bar 1 style • Click OK • Click and drag the scale bar to a position on the bottom center of your layout • Right-click on the scale bar and select Properties • Click on the Scale and Units tab • Set Number of divisions: to 4 • Set Number of Subdivisions to 2 • Click on Show one division before zero • For When resizing… select Adjust Number of Divisions • For Label Position: select below bar • For Division Value: type in 12000 Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
Your window should now look like the graphic below: • Click OK • You may have to resize the scale bar so that it looks like to the graphic below: Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
Save your map – File > Save Step 4: Printing/Exporting your map • After you have finished developing your map and have save it to a .mxd file your next option is to either export your map to a raster format for use in another software package such as Microsoft Word or print the map to an output device. • First you will print your map – it is always a good idea to preview the map before sending it to the printer. • Click on File > Print Preview • If everything looks OK the click on the Print tab – this will bring up the Print window • Click on the drop-down for Printer Engine: and select ArcPress Printer (note: not all output devices will allow you to use ArcPress, in that case you will have to stay with either the Windows Printer or PostScript Printer engines). • Click on the Properties… tab to bring up the ArcPress Printer window • In this window we can change such things as Resolution, Gamma, Brightness etc. – click on the General tab and set the Resolution to 300 • Click OK • Click OK again to send you map to the printer Now let’s try and export our map for use in a Word document. • Click on File > Export Map… • For Save in: browse to C:\Student\Exercise9 • For File name: type inmap9 • For Save as type: select JPEG(*.jpg) • Make sure the General tab is selected and set Resolution: to 150 • Click the Save tab to apply the export and close the window • Exit ArcMap Underground Mine Mapping Using GIS | ArcMap Display | Exercise 7
