All in all, you found a point on the graph with known coordinates. Then start the GPS at hand, manually enter the coordinates of that point, and define a waypoint. Then start the GPS navigation function, the target is that point. At this time, the general GPS receiver will automatically calculate the straight-line distance and azimuth to that point. Note: The azimuth angle is generally the angle that true north is 0 degrees and is rotated clockwise. For example, facing north, the northwest bearing is a number between 270-360 degrees (fourth quadrant), and the northeast is a number between 0-90 degrees (first quadrant). According to the scale of the map, calculate the length of the straight-line distance from here to that point on the map, which is generally a number in centimeter units. Use a compass to take the known point as the center, and draw a circle with such a long distance as the radius. Then draw a vertical line (parallel to the nearest known meridian) through this known point. This way, our current position is on the circle. According to the theorem that the sum of the interior angles of a triangle is equal to 180 degrees, and we only know that what we are going to operate is a right triangle, according to the azimuth angle that has been measured, the angle between the known point and the meridian can be obtained anyway. And the straight-line distance we know is the hypotenuse of the triangle, according to the trigonometric function formula:
hypotenuse X sin(angle) = vertical side or hypotenuse X cos(angle) = horizontal side
Find any vertical side of a triangle. On the map, use a ruler to draw two right-angled sides according to the length, and the point where the circle intersects is where you are now. As long as your satellite signal error is not large and the map is serious, the calculation error is generally quite small. Of course, I hope you have a calculator that calculates trigonometric functions, or you have a similar function calculator installed in your phone. This will find your position on the map. A simpler way is to draw a straight line directly according to the angle between the known points, and the point where it intersects the circle is the current position. However, the error of this labeling is larger than that of the previous calculation method, because the angle measurement of the protractor is generally not very accurate.
