As shown in the figure, (1) is a city of ancient buildings in an ancient tower at the bottom of the building plan, please use the knowledge you have learned to design how to measure the outside of the ancient tower

Methods are as follows:

1, adjust the latitude and longitude for the horizontal state, the first latitude and longitude will be looking at the A′ point, and the latitude and longitude of the horizontal angle of zero, and then rotated latitude and longitude to look at the C′ point, which is displayed on the latitude and longitude, the "angle of the number of "This is the size of the angle between the two lines A′B′; B′C′, which is the same as the angle between the two lines AB, BC.

2, this method is not a profound method, as long as the knowledge of measurement will be people, belong to the ordinary measurement. The accuracy of the measurement result: the more detailed the measurement process operation of the surveyor, the higher the accuracy of the measurement result. The higher the precision of the latitude and longitude instrument used, the higher the precision of the measurement results.

The role of the building plan:

The building plan, as an important part of the architectural design and construction drawings, reflects the functional needs of the building, the plan layout and its composition of the plane of the relationship between the building elevation and the internal structure of the key aspects of the decision. It mainly reflects the building's plane shape, size, internal layout, ground, doors and windows of the specific location and floor space and so on.

So, the building plan is an important basis for the construction of new buildings and construction site layout, but also the design and planning of water supply and drainage, strong and weak power, HVAC equipment and other specialized engineering plans and draw the basis of the pipeline integrated map according to.
