Do you want to know everything about imagery processing?

If you are looking to extract information from raw satellite imagery, there are some regulations to follow.

You should know that satellite imagery processing in Australia requires proper geometric correction and coordinative projections to be successful.

In its essence, image processing allows you to perform digital operations on any image collected by the satellite or otherwise. Moreover, this image can then be enhanced to extract useful information.

There are numerous processing levels that you need to adhere to as well. It helps with geo-location and more. Here is everything you need to know about this.

The Definition of Imagery Processing

As mentioned earlier, image processing is a way in which you can gain information from images. With it, you can perform analysis and operate on images to acquire data. Moreover, you can do this by enhancing the image quality and extracting useful information.

In a way, this can be referred to as a signal processing entity.

In this, you input an image and gain valuable and authentic data. Therefore, the output from imagery processing is the feature associated with any image.

What is Satellite Imagery Processing?

It refers to the process in which you gain images of the earth from artificial satellites. It acts as a subdivision of any research and development agency where they follow guidelines to take pictures of the planet.

The image comes out in a digital format which high-end computers can later process.

Government organisations use this technique to extract and collect information from any crime scene. Therefore, this technology has now become famous and requires a process that is developing every day.

Due to this, engineers and computer science experts can formulate research more straightforward and quicker.

Steps Involved in Image Processing

Ideally, image processing of any kind requires a three-step procedure to be functional. The steps are:

  • Utilising image acquisition tools to import the imagery
  • Manipulating the image to analyse it and gain data
  • Generating an output where the picture gets altered and a report is made

Once the image gets processed, you can easily create an account based on the analysis of the modified image.

Workings of Satellite Imagery Processing

Satellites use electromagnetic radiation to reflect the images from the earth. Hence, passive sensors collect this radiation, analyse it and send it back to the world as thermal imagery.

You can see satellite imagery in three resolutions:

  • Spatial
  • Temporal
  • Spectral
  • Radiometric

Different Methods of Image Processing

There are two methods to process, namely – Digital and Analogue image processing.

In the Analogue process, you can get hard copies of the images. Then, the analysts will use various fundamentals to determine the visual interpretation of the printouts.

On the other hand, the Digital process involves the manipulation of any digital image through computers. Therefore, the image will undergo three phases –

  • Pre-processing
  • Enhancement
  • Display

Once these phases are complete, you can extract the information from the digital image.

Summing Up

To sum up, satellite imagery processing is a way to detect what is happening on the planet from a more excellent viewpoint. With imagery processing, you can gain information from Digital and Analogue images.

It gets analysed through different techniques, and you get a final output that is beneficial for your requirement. So, with this technology, you can see what the naked eye cannot.
