Remote sensing is a technology used to acquire data about the Earth's surface from a distance, typically using sensors mounted on aircraft or satellites. In the case of aerial photography, remote sensing is used to capture images of the Earth's surface from above. These images can then be processed and analyzed to create GIS data.
Aerial photography is a common method of remote sensing used to acquire GIS data. In this method, cameras are mounted on aircraft and used to capture high-resolution images of the Earth's surface. These images can be used to create maps, measure distances, and identify features on the ground.
In addition to traditional aerial photography, other remote sensing techniques can also be used to acquire GIS data. For example, multispectral imaging sensors can capture images in multiple wavelengths of light, allowing for the identification of different types of vegetation or land cover. LiDAR (Light Detection and Ranging) sensors can be used to create detailed 3D models of the Earth's surface, which can be used for terrain mapping and other applications.
Overall, remote sensing is a powerful tool for acquiring GIS data in aerial photography, allowing for the collection of detailed and accurate information about the Earth's surface from a distance.

Remote sensing is the science of acquiring information about the Earth's surface without actually being in contact with it. This can be done using a variety of sensors, including cameras, lasers, and radar. Aerial photography is a type of remote sensing that uses cameras mounted on aircraft to take images of the Earth's surface.
Aerial photography has been used for over a century to create maps and other Geographic Information System (GIS) data. GIS is a computer system that allows users to store, manipulate, and analyze spatial data. GIS data can be used to create maps, charts, and other visualizations that can help us understand the world around us.
Aerial photography is a valuable source of GIS data because it can provide high-resolution images of the Earth's surface. These images can be used to create detailed maps, identify land use patterns, and track changes over time. Aerial photography can also be used to create 3D models of the Earth's surface, which can be useful for planning and development.
Here are some of the specific ways that remote sensing is used to acquire GIS data in aerial photography:
- Cameras: Cameras are the most common type of sensor used for aerial photography. They can be used to capture images in a variety of wavelengths, including visible light, infrared, and ultraviolet. This allows us to see different features of the Earth's surface, such as vegetation, water, and buildings.
- Lasers: Lasers are used to create lidar (Light Detection and Ranging) data. Lidar data can be used to measure the elevation of the Earth's surface. This information can be used to create topographic maps, which show the shape of the land.
- Radar: Radar (Radio Detection and Ranging) is used to create radar data. Radar data can be used to penetrate clouds and vegetation, which makes it useful for mapping areas that are not easily visible from the air.
