What are the two methods of land navigation?
It is used to locate distant or inaccessible points or objects such as enemy targets and danger areas. There are two methods of intersection: the map and compass method and the straightedge method. Orient the map using the compass.
What are the three land navigation methods?
Everything in land navigation begins with an azimuth. An azimuth is a horizontal angle measured clockwise by degrees or mils between a reference direction and a line to an observed or designated point. There are three base directions or azimuths: true, grid, and magnetic. The Army uses azimuths to express direction.
What kind of map do I need for land navigation?
For land navigation purposes, go with a map that has a 1:50,000 to 1:24,000 scale. 1:24,000 scale maps are the USGS standard, and it’s what I learned how to do land navigation with, so that’s my preference.
What do you need for land navigation?
Basic land navigation only requires three (3) “tools”. A topographic map, a compass (for this Instructable I will be using a basic orienteering compass), and a dry erase marker (if your map is laminated or sealed in plactic) or pencil.
Is land navigation hard?
Land Nav at TBS is miserable. It is incredibly difficult, and in some cases unnecessarily so. Night land Nav is conducted without NVG/NOD’S, so you literally Sprint through the tree line to catch as many points as you can before all light is gone and you have to stumble your way through what’s left of your time.
Where can I get land navigation maps?
How do I find, download, or order topographic maps?
- Map Locator on the USGS Store — Search and download free digital maps in GeoPDF format or order paper maps.
- TopoView — The largest selection of digital options.
- Advanced users can also use The National Map and the Geographic Names Information System (GNIS) to download digital topographic maps.
How do I prepare for Army land navigation?
prepare for school:
- Stop cheating at land nav now.
- Do some trail running.
- Run the land nav course.
- Plan then go.
- Darkness is for movement.
- Don’t trust the roads on the map.
- Don’t cheat.
- Know when to stop.
How do you land navigation at night?
a. The basic technique used for nighttime land navigation is dead reckoning with several compasses recommended. The point man is in front of the navigator but just a few steps away for easy control of the azimuth. Smaller steps are taken during night navigation, so remember, the pace count is different.
How accurate is a 4 digit grid coordinate?
4 digits – 2306 – locates a point with a precision of 1,000-meters (a neighborhood size area). 6 digits – 234064 – locates a point with a precision of 100-meters (a soccer field size area). 8 digits – 23480647 – locates a point with a precision of 10-meters (the size of a modest home).
What are the 5 major terrain features on a military map?
The five major terrain features are: Hill, Ridge, Valley, Saddle, and Depression. The three minor terrain features are: Draw, Spur and Cliff.
What are the 5 major map features?
Most maps will have the five following things: a Title, a Legend, a Grid, a Compass Rose to indicate direction, and a Scale.
What does a cliff look like on a map?
Cliff: A cliff is a vertical or near vertical feature; it is an abrupt change of the land. Cliffs are also shown by contour lines very close together and, in some instances, touching each other.
What are the 7 most common terrain features found on a map?
Terrain Features on a Map (MGRS)
- Major Terrain Features.
- Hill. A hill is an area of high ground.
- Saddle. A saddle is a dip or low point between two areas of higher ground.
- Valley. A valley is a stretched-out groove in the land, usually formed by streams or rivers.
- Minor Terrain Features.
What is the distance between grid lines on a map?
All OS maps are criss-crossed by vertical and horizontal grid lines (coloured blue on OS Explorer maps) which are 4cm apart on 1:25,000 scale maps and 2cm apart on the 1:50,000 scale. A grid reference uses six figures to identify a particular spot on a map that is 100 metres square.
What does a spur look like on a map?
You can spot a spur on the map quite easily – it looks like a long, narrow tongue of contour lines, dropping away from a mountain top or a ridge. Usually its sides will be quite steep, but its top will slope gently downwards.
What is the difference between valleys and spurs?
A simple way to tell a valley from a spur when looking at contour lines is to remember that if the ‘V’ points uphill it’s a valley, if it points downhill it’s a spur. Contours bunched together on either side of lower, more evenly spaced contours show a valley or col between two areas of high ground.
What’s the difference between a spur and a ridge?
Ridge (Also: Arete or Spur) – A continuous elevated terrain with sloping sides. In the map represented by “U” or “V” shaped contour lines where the higher ground is in the wide opening. Arete is a narrow ridge and a Spur is a smaller ridge branching off a summit or a main ridge.
