| + | |||
| + | A coordinate system is a way of specifying a location on map | ||
| + | |||
| + | 3 systems you're likely to use in SAR. | ||
| + | |||
| + | * UTM - Universal Transverse Mercator | ||
| + | * Geographic Coordinate System - Latitude/Longitute | ||
| + | * Legal Land Description - Section, Township. Roads and Approaches | ||
| + | |||
| + | {{lesson slide||}} | ||
| + | '''UTM''' | ||
| + | * SAR uses mostly | ||
| + | * taught in SAR fundamentals | ||
| + | |||
| + | * 3 parts: ZEN | ||
| + | ** Zone | ||
| + | ** Easting | ||
| + | ** Northing | ||
| + | {{lesson slide||}} | ||
| + | '''Zones''' | ||
| + | |||
| + | * Each zone is a grid system that stretches from near the antarctic to the far north | ||
| + | * different strips necessary because laying a square grid on a round world | ||
| + | * Each zone is 6 degrees wide | ||
| + | * Pincher Creek is right at the boundary between zone 11U (on west) and zone 12U (on east) | ||
| + | * Each map shows it's zone | ||
| + | {{lesson slide||}} | ||
| + | '''Northing''' | ||
| + | * how far north of the equator (in meters) | ||
| + | * written on left and right edge of map | ||
| + | * horizontal blue lines have same northing | ||
| + | * only 2 of the digits are shown for most blue lines | ||
| + | |||
| + | {{lesson slide||}} | ||
| + | '''Easting''' | ||
| + | * relative to the center of the Zone | ||
| + | * center of Zone is 500,000m | ||
| + | * bigger number the further east you go | ||
| + | * smaller number as you fo west | ||
| + | * written on the bottom and top edge of the map | ||
| + | * vertical blue lines have same easting | ||
| + | * sometimes starts over from 99 to 00 (with carry) | ||
| + | |||
| + | {{lesson slide||}} | ||
| + | '''Stating a UTM''' | ||
| + | * order: Z - E - N | ||
| + | * e.g. 12U 710000 5477000 | ||
| + | * ''find this location: middle of Beauvais Lake'' | ||
