What are the elements of image interpretation?

The most basic are the elements of image interpretation: location, size, shape, shadow, tone/color, texture, pattern, height/depth and site/situation/association. They are routinely used when interpreting aerial photos and analyzing photo-like images.

What is image interpretation in GIS?

Definition. Image interpretation is the process of examining images and identifying and judging their significance by considering their location and extent. Expertise in image interpretation is achieved over the period of time through experience.

What are the different types of image interpretation?

In this lesson, you learned about three types of imagery: natural color, panchromatic, and color infrared. You learned about the importance of the GSD for imagery interpretation, and the seven types of cues used by the image interpreter: shape, size, pattern, texture, tone (and spectral signature), shadow, and context.

What is imagery interpretation?

What elements are necessary for interpretation?

These nine basic elements- shape, size, tone, shadow, pattern, texture, site, association, and resolution-are elements of photographic interpretation common to several sensors.

What are image interpretation techniques?

Image interpretation is the process of examining an aerial photo or digital remote sensing image and manually identifying the features in that image. This method can be highly reliable and a wide variety of features can be identified, such as riparian vegetation type and condition, and anthropogenic features. Read more.

Which is a basic first order element in image interpretation?

Basic or First order elements (Tone), Second order (Texture, shape, size, pattern) and Third order (Location, Association, Shadow and Height). Visual interpretation using these elements is often a part of our daily lives, whether we are conscious of it or not.

What are image interpretation keys?

It provides guidance about the correct identification of features or conditions on the images. Generally, eight standardized keys are established to eliminate the difference between different interpreters.
