Document Summary
Map: a generalized view of an area (a model) as seen from above and reduced in size. Geography employs spatial analysis of 5 topics: types of maps, map elements, coordinate systems, map projections, geomatics. Planimetric- show horizontal positions (of boundaries, bodies of water, economic, & cultural features, etc) ex, road maps. Thematic- (planimetric) + add spatial distribution of some type of data over a geographic area, qualitative or quantitative. Topographic- add portrayal of physical relief through the use of contour lines that connect all points at the same elevation. Illustrates: natural physical features (topography: slopes, high points, depressions; water bodies: rivers, lakes, canals, vegetation, submerged areas and bogs) and infrastructure and other human made features (boundaries, mines, buildings, roads, transmission lines and pipelines) 4 map elements: map scale- scale: the ratio of distance on a map to that on the earth (1:1 = 1cm:1cm). Small scale: large denominator, not a lot of detail, shows a large geographic area.
