Question

Images a and b of ground points A and B appear on a vertical photograph taken froma flying height of 2625 m above datum. A 153.16-mm-focal-length camera was used. Points A and B have elevations of 407 m and 311 m above datum, respectively. Measured photo coordinates of the images are xa--60.2 mm, ya 47.3 mm, xb- 52.4 mm, yb 80.8 mm. Calculate the horizontal lengths of line AB. (a) If a third point C was measured with elevation of 379 m above datum and photo coordinates xc= 94.1 mm and yc =-79.7 mm. Calculate the area within triangle ABC (b)
