Assignment 1-SPACE RESECTION COMPUTATION

The images of four ground control points ABCD appear on a photograph taken with a camera of focal length 112.05.the refined photo coordinates ad the corresponding ground coordinates of the points are as show

Point photo coordinates (mm) ground coordinates (mm) elevation

X y x y

A -64.097 72.924 2294.96 4735.29 1236.46

B 64.017 77.183 2274.05 5263.62 1242.56

C -23.087 -39.191 2736.69 4928.94 1313.25

D 64.353 -37.129 2734.89 5269.75 1274.90

Compute

1. the approximate values of X0, Y0, Z0 and K using the data for points A, B

2. the values of the exterior orientation elements based on the data for points ABC

3. the most probable values of the elements, based on all the data given

Hence write a two page report that:

(a) Outlines the objectives of the exercise

(b) The steps in the computation and procedures

(c) The results in each step of computation and comment on them

(d) Give a copy of the coding of your program(s) for the computation
