Document Summary
Spatial science (spatial distribution; spatial extent, pattern and system; spatial process. Absolute (latitude and longitude: definition; range; important lines) Scale: map projection (1) the necessity of map projection (2) the use of different surfaces for map projection: (3) four types of map projection to preserve certain properties. Conformal (shape): preserves shapes & preserve local angles. Equivalent (area): represents areas in correct relative size. Test 1 outline (4) map elements: title, north arrow, legend and scale. Verbal scale, graphic scale, representative fraction scale. Large- vs. small-scale maps (a large-scale map = a large amount of detail for a small. Gis definition: a geographic information system (gis) is a computer system for capturing, storing, querying, analyzing, and displaying geographically referenced data: input spatial information, data conversion. Gis functions: storage & management of information, manipulation of spatial data, presentation of data, hardware, software. Data types: discrete and continuous features (definitions; identification)
