At the description of geographical, archaeological, toponymic and many other objects it is necessary to specify their coordinates. For the mountain the defining point is the top. It is possible to determine its coordinates in different ways. It depends on the required accuracy of measurements.
It is required to you
- - computer with the Google Mother Earth program;
- - GPS navigator;
- - tool for measurement of corners;
- - geographical large-scale map;
- - sheet of paper;
- - pencil.
Instruction
1. If you need to describe the mountain to which there is no opportunity to reach, determine top coordinates by the card. You will find the highest of them even on the paper card, and quite often also coordinates which just need to be rewritten are specified there. Do not forget to specify northern or southern latitude and the western or east longitude.
2. Modern programs give the chance to determine coordinates of almost any objects. Download the Google Mother Earth program. Deliver it to yourself on the computer. It is established and started in the standard way.
3. Consider what appeared at you on the screen after start. You will find top necessary to you in the right top corner if you a little work as buttons of management. Guide the cursor at top. In the lower part of a window coordinates of a standard look, to within seconds will appear. Parts of the world are designated by letters C, Yu, Z and B after figures.
4. Electronic cards and other computer programs give the chance to determine coordinates of many objects, without rising from a chair. However sometimes all-such there is a need to make it traditional geodetic methods. Determine reference points by the navigator. Determine their coordinates and height above sea level. Measure between them distance. Designate them on the plan or the map or just write down.
5. By means of any goniometric tool carry out a notch of corners. If you are able to work with a theodolite or the tacheometer, use them. It is possible to use the mountain angle meter - a theodolite of the simplified design, or a mountain compass. The last is equipped with the clinometer for measurement of vertical angles.
6. Mentally lower from mountain top a perpendicular on its basis. You will expose a mountain compass on level strictly horizontally. Measure a corner between the direction on the second reference point and on the lower point of a perpendicular. In the same way measure a corner from the second point. Calculate for the horizontal plane of distance from reference points until the end of a perpendicular. Designate a point on the map or the plan. The plan has to be with a coordinate grid too.
7. Define horizontal corners from the line of the direction between a reference point and a perpendicular to a parallel or to a meridian. Construct rectangular triangles. From the lower point of the perpendicular lowered from top carry out one more perpendicular to a parallel (meridian) on which there is a reference point. You received a rectangular triangle at which the hypotenuse (distance from a reference point to a top projection to the plane) and a corner between this hypotenuse and a corner is known to you. Calculate other parties, having added to them distance from basic points to a parallel or a meridian, having received thus top coordinates in the horizontal plane.
