When you open one of the Ilustrator files, you will be presented with a map featuring a coastlines, borders, rivers, cities, names, graticules (lines of latitude and longitude), and a scale. To get the full benefit from these files, make sure you have the “Layers” floating palette open by choosing “Show Layers” from the “Windows” menu. You will see from the Layers palette that not all layers are checked. By clicking at the left margin of any other layer name a “bullet” appears, and that layer becomes visible.
 
The layers are as follows:
Box rule: This is a 1 point black box rule of precisely the same dimensions as the corresponding relief map on your Mountain High Maps disc.
Scales: This is a “grouped” graphic – to ungroup it, select “Arrange > Ungroup.” Most of the projections used in the Mountain High Map collection are “equal area,” so the scale can be used to measure distances at any point on the map. However, some distortion occurs on the world maps, and on these maps the scale is calibrated at the Equator.
Graticules: This is a 0.25 point red line describing the meridians of longitude and parallels of latitude.
Graticule labels: This contains annotation for the intervals between each graticule, measured in degrees.
City/town locations: These are 1.5mm diameter black dots indicating the locations of major cities and towns.
City/town names: This layer displays the names of all of cities and towns featured on the opened map. The font used is Helvetica. To change the font select a name by clicking on it (you can select every name by making all the other layers invisible and then choosing “Select all” from the Edit menu), and then change the font using the “Type > Font” menu.
River names: This layer displays the names of rivers featured on the opened map. The font used is Helvetica. To change the font select a name by clicking on it (you can select every name by making all the other layers invisible and then choosing “Select all” from the Edit menu), and then change the font using the “Character” palette.
Country Names: This layer displays the names of all of the countries featured on the opened map. The font used is Helvetica. To change the font select a name by clicking on it (you can select every name by making all the other layers invisible and then choosing “Select all” from the Edit menu), and then change the font using the “Charactert” menu.
Countries: When you select any country from those listed, that country will be visible as a 0.25 point (hairline) black path. To change the thickness and color of an individual country border, select the path (hide all the other layers and choose “Select all” from the Edit menu), and and apply new attributes using the “Paint Style” palette.
Coastline: This is visible as a 0.25 point (hairline) cyan path.
Rivers: These are visible as 0.25 point (hairline) cyan paths.
Borders: These are visible as 0.5 point magenta paths. Country borders are mostly colored magenta; those borders which are colored purple are either disputed or undefined Refer to the “Disputed borders” document in this folder for more information.
Lakes Fill: This layer contains white fills for lakes and inland water areas.
Placed art: This layer is empty and is provided for placing the corresponding Mountain High Maps relief image, so that all other layers are on top. NOTE: Version 5.0 of Illustrator does not import TIFF files. If you want to include a Mountain High Maps relief image in your Illustrator map, you must save the TIFF files as EPS files from an application such as Adobe Photoshop. If you want to color them, do so before you save them as EPS files, because Illustrator does not allow you to edit bitmapped images.
The Illustrator versions of Mountain High Maps are constructed with high cartographic integrity, and consequently they are made up of very detailed and complex paths. This can present problems when printing with low amounts of printer memory (identified by the printer as “limitcheck” errors) if left as continuous, joined paths. Because PostScript limits the number of points in a path – and some of the map outlines would contain many thousands of points as joined paths – we have split the more complex paths into smaller chunks.
To use the Illustrator files in other applications, export your document as an EPS file – choose “Save As…” from the “File” menu. Some applictions, such as Adobe Photoshop and Macromedia FreeHand, will open Illustrator files directly.
