CV-23 - Map analysis
- Create a profile of a cross section through a terrain using a topographic map and a digital elevation model (DEM)
- Measure point-feature movement and point-feature diffusion on maps
- Describe maps that can be used to find direction, distance, or position, plan routes, calculate area or volume, or describe shape
- Explain how maps can be used in determining an optimal route or facility selection
- Explain how maps can be used in terrain analysis (e.g., elevation determination, surface profiles, slope, viewsheds, and gradient)
- Explain how the types of distortion indicated by projection metadata on a map will affect map measurements
- Explain the differences between true north, magnetic north, and grid north directional references
- Compare and contrast the manual measurement of the areas of polygons on a map printed from a GIS with those calculated by the computer and discuss the implications these variations in measurement might have on map use
- Determine feature counts of point, line, and area features on maps
- Analyze spatial patterns of selected point, line, and area feature arrangements on maps
- Calculate slope using a topographic map and a DEM
- Calculate the planimetric and actual road distances between two locations on a topographic map
- Plan an orienteering tour of a specific length that traverses slopes of an appropriate steepness and crosses streams in places that can be forded based on a topographic map
- Describe the differences between azimuths, bearings, and other systems for indicating directions
