Significance of Color Infrared Orthophoto

Significance of Color Infrared Orthophoto

There was a time when people couldn't realise that they can cherish their moments with actual clarity images and pictures. They had to expect some magic to realise this dream. However the fast pacing technology made the change in a very short time than expected. Today people can capture colour and motions at their freewill and in the time they want and cherish it for several years without even spoiling the images. Thanks to all modern photographic methods!

While we talk about modern photographic methods, one thing that needs essential notice is infrared photography. Infrared photography uses infrared rays to capture the pictures. Infrared rays fall in the range of 700nm to 900nm wavelength in the visible light spectrum. It has less frequency and high wavelength, which enables it to travel long distances without being scattered by air particles. This property of the infrared rays is made use in infrared photography. Infrared photography achieves high clarity in pictures because of its less scattering property.

Infrared photography was first used in the early 20th century. Earlier photographs were mainly in black and white. However, with the introduction of sophisticated technologies in cameras, colour infrared (CIR) photography is now possible. Colour infrared photography provides high definition and high depth pictures enabling clear view of objects.

Black and white images are otherwise called panchromatic. They were the most widely used images in the earlier days, before colour images came in. Several orthophoto creation projects were completed using the black and white colour images. Black and white images are less expensive and have very small size. This makes it more easy to use. However they lack clarity of objects and cannot help in detail study of topography and other geological factors.

One of the key areas where Colour infrared photography finds application is in orthophotography. Ortho photography is the process of creating aerial images of geography with precision in dimension and depth. The colour infrared ortho photo helps in studying the geography, weather, land usage, country planning, town planning, utilities management, etc. With the growing technology, the colour infrared image creation can be applied in variety of sectors.

The images in colour infrared orthophoto showcases true colours of earth and the topography. This enables the people to study and interpret varied features of the geography and enhance accurate learning. Compared to black and white infrared images, colour infrared images have in-depth clarity and easily identifiable objects. In addition, users can see added features that low resolution pictures and black & white images cannot exhibit. Colour infrared orthophotos are suitable for studying man made topographies. Colour infrared orthophotos have very large file size, which makes downloading and uploading a tad difficult. However, the modern compressing tools have made orthophotos easier to handle.

Concluding, Colour infrared photography is the most modern technique used for image creation. Orthophoto created using infrared photography enhances clarity of the images. Therefore, Orthophoto can be used for space and resource management services. Colour infrared orthophoto also details the topographical and other geological information.
