CST Level 1 Land Surveyor Certification Practice

What is the primary focus of photogrammetric maps?

1. Topography and area details

2. Surveying aerial land features

3. Engineering project layouts

4. Geographic data collection

The correct answer is: Topography and area details

Photogrammetric maps primarily focus on representing topography and area details through the use of photographs taken from aerial perspectives. These maps are produced by analyzing aerial images to extract three-dimensional information about the terrain, allowing surveyors to create accurate representations of landforms, elevations, and land cover types. The process of creating photogrammetric maps involves the use of stereoscopic techniques, where overlapping images are combined to visualize depth and surface characteristics. This detailed topographical information is essential for various applications, including land use planning, environmental studies, and geological assessments. While surveying aerial land features and collecting geographic data are certainly involved aspects of photogrammetry, the primary emphasis is on accurately capturing the topographical features of the land and the relationships between different geographic elements. This makes topography and area details the core focus of photogrammetric mapping.
