This media file is a photograph of an open book, likely a textbook or study guide, focused on surveying. The page is filled with text and diagrams. The left side of the page contains a diagram illustrating an "open traverse," represented by connected lines labeled A, B, C, D, and E, forming a zigzag path. Below the diagram, it explains that this type of traverse is used for surveying rivers, roads, and railway routes and mentions using reference objects like church towers or factories. The right side of the page discusses different surveying methods. It mentions "Theodolite traversing," describing the instrument and its accuracy. Further down, it introduces "Compass traversing," explaining how a prismatic compass aligns with magnetic north and its relationship to the North-South Meridian. It also notes that compasses are cheaper and commonly used. The text also lists "Compass Traverse Instruments," with "A prismatic compass" being the first listed item. A small illustration of a theodolite on a tripod is present, labeled "Fig. 21.9 Theodolite." The page number "143" is visible at the bottom right. The overall setting appears to be indoors, likely a study or library environment, with no people or specific time of day or weather cues visible. The text is in English.
