Presentation transcript:

Pros and Cons of Paper Maps Pros of Paper Maps Necessary for certain localities, such as distances by road and topographic features, especially when GIS layers are not readily available Extents more readily obtained Old paper maps may be the only option for obtaining coordinates for historic localities Cons of Paper Maps Time-consuming Good quality paper maps may be hard to find Map printing errors

Map Anatomy: Map Scale

Map Anatomy: Map Scale usually recorded as a ratio, such as 1:100,000, or a fraction, such as 1/100:000 Large scale maps, such as 1:10,000, show finer detail Small scale maps, such as 1:500,000, show greater areas

Map Anatomy: Map Scale 1:24,000 Large Scale Map

Map Anatomy: Map Scale 1:100,000

Map Anatomy: Map Scale 1:250,000

Map Anatomy: Grid

Map Anatomy: Grid Shows the placement of the parallels and meridians on maps Used to determine latitude and longitude Maps with no grid recorded cannot be used to determine coordinates – only to determine extents

Map with no grid labeled Map Anatomy: Grid Map with no grid labeled

Map with no grid labeled Map Anatomy: Datum Map with no grid labeled

Map Anatomy: Datum If datum is recorded, usually found near the map scale or publisher’s name Use Horizontal Datum, not Vertical Occasionally, if no datum is recorded but the reference ellipsoid is, then one can determine the datum using the pdf document found at http://earth-info.nga.mil/GandG/publications/tr8350.2/wgs84fin.pdf (Use Appendix B)

Determining Coordinates from Paper Maps Paper maps are necessary when gazetteers will not report needed coordinates Especially useful for distances by roads and topographic features like rivers and mountain ranges Pay special attention to the grid lines and the hemisphere (latitudes in the southern hemisphere are negative, and longitudes in the western hemisphere are negative)

Determining Coordinates from Paper Maps

Determining Coordinates from Paper Maps: Latittude

Determining Coordinates from Paper Maps: Latitude

Determining Coordinates from Paper Maps: Longitude

Determining Coordinates from Paper Maps: Longitude

Determining Coordinates from Paper Maps: Error Calculation

Determining Coordinates from Paper Maps: Determination Reference For Determination Reference: be sure to include the following: Map name Publisher name Map Scale Map Date Example: United States Geological Society (USGS) Topographic Map California, 1956, map scale 1:24,000, map name “Boone”
