3

Dar la nomenclatura de una brújula de orientación.


Lensatic Compass


The lensatic compass consists of three major parts: the cover, the base, and the lens.

Escala


4f

Medición


4g

Retro-acimut


4h

4k

Formas de la tierra




5

Demostrar cómo encontrar el acimut magnético.



6

Demostrar la manera de andar con un acimut magnético.


Compass preset at 320 degrees.



7

Conocer dos métodos para corregir la declinación.


Method #1

(These directions assume your orienting arrow lines up with the North indicator on your compass dial, meaning the compass has not been adjusted for declination).


8

Ser capaz de orientarse por sí mismo y un mapa, por inspección y por una brújula.


Place the compass on the map so the baseplate parallels the north-to-south map neat line. Rotate the dial until compass ring North agrees with map North. Add or subtract the amount needed to adjust for local magnetic declination (subtract if local declination is positive, add if local declination is negative); if your adjustable declination compass is already calibrated for local declination, you don’t need to add or subtract, just make sure compass ring North (not the orienting arrow) agrees with map North. Holding the map and compass steadily (the baseplate should still be on the north-to-south map neat line), rotate the map and compass all in one motion until the red magnetic needle overlays the orienting arrow. Again, make sure there is no interference from metal when you perform this (ex: rebar in concrete). Your map and your compass are now oriented to true north. Compare the physical features around you with your map to help derive your location on the map..


9

Explicar la triangulación y su uso.


Resection is a method of using a compass and a map to determine your current position. The first step is to find a feature of the landscape that you can also identify on the map. This could be a mountain peak, an intersection, a bridge, or even a utility pole (some topographic maps mark where high-voltage lines are, as well as the position of the poles that hold them up). The closer these two landmarks are to 90° offset from one another, the more accurate the resection will be. For instance, if the first landmark is at 115°, choose the second one as close to either 205° (115°+90°) or 25° (115°-90°) as you can. This is not a hard and fast rule, and the prominence of the landmark may well be more important than the 90° offset. Once you have shot an azimuth to the first landmark, calculate the back azimuth, and plot a line on your map from the landmark towards (and past) your current position (which should be somewhere on that line). Be sure to correct for declination when plotting this line. Then shoot the azimuth of the second landmark, and plot it's back azimuth on the map as well, again correcting for declination. If your readings are accurate and your plotting was done carefully, your current position should be very close to where these two lines intersect.


10

Demostrar su habilidad en el uso de un mapa y/o una brújula, siguiendo el curso de una milla (1.6 km) a campo traviesa con un mínimo de cinco puntos de lectura o puntos de control.
