Return to Outline Copyright © 2009 by Maribeth H. Price 3-4 Map Design Process Determine the objectives of the map. Decide on the data layers to be included. Plan a layout. Choose colors and symbols. Create the map.

Return to Outline Copyright © 2009 by Maribeth H. Price 3-5 Questions to consider Who will be using the map? Under what circumstances will the map be used? Is the map likely to be copied or faxed? What objectives should the map achieve? How sensitive is the map information?

Return to Outline Copyright © 2009 by Maribeth H. Price 3-6 Choosing layers Which layers are important? How can you ensure legibility?

Return to Outline Copyright © 2009 by Maribeth H. Price 3-7 Planning the layout Poor design Better design

Return to Outline Copyright © 2009 by Maribeth H. Price 3-8 Basic principles for balance Maximize size of map relative to titles, legends, etc. Distribute elements evenly on the page, avoiding blank or cluttered areas Align straight edges and use neatlines to enclose map elements

Return to Outline Copyright © 2009 by Maribeth H. Price 3-9 Choosing symbols

Return to Outline Copyright © 2009 by Maribeth H. Price 3-10 Choosing symbols Natural earth tones usually look better than strident colors Use pastels for most of map; use bold colors sparingly for emphasis Take advantage of the psychological aspects of different colors and symbols Mimic phenomena, such as using blue to represent water Make ramps easy to understand Apply emphasis with color, size, and thickness

Return to Outline Copyright © 2009 by Maribeth H. Price 3-11 Symbol psychology Where is the water? Where is there less rain? Which towns have more people? What’s there? Where’s the danger?

Return to Outline Copyright © 2009 by Maribeth H. Price 3-12 Vibrating Moiré pattern obscures roads Use see-through lines to indicate urban areas Symbol tricks

Return to Outline Copyright © 2009 by Maribeth H. Price 3-13 Choosing symbols Which one looks more aesthetic? Which one is easier to understand? Which one shows the roads better?

Return to Outline Copyright © 2009 by Maribeth H. Price 3-14 Improving a world map More pastels Natural colors Use ramp to indicate increasing population Emphasize the important information

Return to Outline Copyright © 2009 by Maribeth H. Price 3-15 Pay attention to details! Crowded Unclear name Abbreviations Poor formatting Much better!!!

Return to Outline Copyright © 2009 by Maribeth H. Price 3-18 Types of coordinate systems Unprojected (GCS) –Geographic coordinate system –Based on spherical coordinates –Degrees of latitude and longitude Projected –Converts spherical coordinates to planar –Set of mathematical equations –Projects 3D coordinates to 2D map

Return to Outline Copyright © 2009 by Maribeth H. Price 3-19 GCS properties Measured in angular degrees Length of longitude degree varies with latitude Introduces distortion when portrayed in a plane as a GIS does Unsuitable as a mapping CS

Return to Outline Copyright © 2009 by Maribeth H. Price 3-20 Avoiding GCS when mapping A map using a Geographic Coordinate system (GCS) appears distorted. Always use a projected coordinate system for mapping

Return to Outline Copyright © 2009 by Maribeth H. Price 3-41 Viewing unplaced labels

Return to Outline Copyright © 2009 by Maribeth H. Price 3-42 Reference scale Sizes of annotation and symbols are specified when they are created. By default they remain the same size as the user zooms in and out. If the user sets a reference scale, the symbols and text can change size. The reference scale is the scale at which symbols appear at their assigned size.

Return to Outline Copyright © 2009 by Maribeth H. Price 3-43 Using the reference scale If the reference scale is not set, then symbols always appear at their assigned size even if the map scale changes (user zooms in or out). If the reference scale is set, then symbols and text change size when the map scale changes. They only appear at their assigned size if the map scale once again matches the reference scale.

Return to Outline Copyright © 2009 by Maribeth H. Price 3-44 Don’t confuse these scale terms The map scale is the ratio of the map units to the ground units, e.g. 1:24,000. It changes when you zoom in or out. The display scale range controls whether a layer is visible only at certain scales. The reference scale is the scale at which symbols and text appear at their assigned size

Return to Outline Copyright © 2009 by Maribeth H. Price 3-45 Annotation Can be created from dynamic labels then edited individually Provides precise control of each label Can be stored two ways –As text in the map document Can be used only within that map document Simple editing using the Drawing toolbar –As a feature class in a geodatabase Can be used in many map documents Requires using the Editor to move and change
