How To Make A Geographic Map
List four questions about map objectives that would influence the design of a map. What am I making this map for and what am I trying to accomplish? Who will be viewing? Why will it be used? Is there privacy issues surrounding the project? 2. What factors should be considered In evaluating the balance of a map? Placement of features, the size of features, alignment of features, usage of space 3. What types of colors generally work best for maps? How can the psychology of colors be used to enhance a map’s meaning?
Pastels and earth are good for big map areas. Bold colors are good for emphasis. Some things have associations with colors. For example green for plant life or blue for water 4. List three common pitfalls that amateurs make when creating legends. Cryptic filenames, poor formatting of numeric numbers and not adjusting neatness for balance 5. What is a geographic coordinate system, and why is it a poor choice for creating maps? This is a bad method for making maps because of the distortion the system makes when projecting the map.
A geographic coordinate system does this cause it is a system based on a sphere. 6. What four properties are distorted by map projections? Which tend to be preserved by conic projections? What distortions are present in TM and State Plane projections? Area Shape Direction and Distance can all be distorted. TM and state plane are better for small area mapping as they tend to preserve area and distance. 7. Examine the map projections on the inside front cover of this text.
List which projection(s) might be suitable for a (a) map of a county, (b) map of the united States, c) United States map used to calculate travel distances, and (d) United States map used to calculate areas. A)= TM or state plane b)= Equidistant Conic or Lambert conformal conic c)= Equidistant Conic d)= Albert Equal Area Conic 8. When does a north arrow not point up? When should a north arrow not be used? If a projection messes up the direction a north arrow cannot be used as It does not conform with the data. A gratuities grid can be used to show north 9.
If you have an Archive license and wish to create and use annotation In different AP documents, how would you need to store It? An annotation Is stored as a feature class In a sedateness. 10. What Is the difference between the map scale, the scale range, and the reference scale? Map scale- Is the ratio of units from the map to the world Scale range- controls the range of the scale at which the features are allowed to appear Reference scale- scale that determines at which symbols or text labels appear at their assigned size CHI GIS By Will-Huber 2.
