A Digital Orthophoto Quadrangle (DOQ) is a digital aerial photograph that has been geometrically corrected, or orthorectified, to ensure that the scale is uniform across the image. This means that the image accurately represents the Earth's surface, allowing for precise measurements and analysis. DOQs are typically produced in a quadrangle format, covering a specific area of land, and are used in various applications such as urban planning, environmental monitoring, and land use management. DOQs are often used in conjunction with Geographic Information Systems (GIS) to provide detailed visual information about a specific area. They can include features like roads, buildings, and natural landscapes, making them valuable for researchers, planners, and government agencies. The data from DOQs can be integrated with other spatial data to enhance decision-making processes and improve resource management.
