##### DM-47 - Geographic coordinate system

- Distinguish between various latitude definitions (e.g., geocentric, geodetic, astronomic latitudes)
- Explain the angular measurements represented by latitude and longitude coordinates
- Calculate the latitude and longitude coordinates of a given location on the map using the coordinate grid ticks in the collar of a topographic map and the appropriate interpolation formula
- Mathematically express the relationship between Cartesian coordinates and polar coordinates
- Calculate the uncertainty of a ground position defined by latitude and longitude coordinates specified in decimal degrees to a given number of decimal places
- Use GIS software and base data encoded as geographic coordinates to geocode a list of address-referenced locations
- Locate on a globe the positions represented by latitude and longitude coordinates
- Write an algorithm that converts geographic coordinates from decimal degrees (DD) to degrees, minutes, seconds (DMS) format
