How to Interpret a Satellite Image: Five Tips and Strategies

  1. Look for a scale.
  2. Look for patterns, shapes, and textures.
  3. Define the colors (including shadows)
  4. Find north.
  5. Consider your prior knowledge.

What are the critical factors to understand when interpreting a satellite image?

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 can be determined from the satellite imagery?

By measuring IR radiation, satellites can infer cloud top temperature, which in turn can be used to infer cloud top height. Therefore, whereas VIS satellite imagery can provide information about cloud thickness, IR imagery primarily provides cloud-top temperature and height information.

What is the most common feature to identify lineaments from satellite data?

The most important features in the area are the presence of drainage lines patterns and fractures. Lineaments, drainages, lithological contacts, and previous fault lines data are important data and used in this research for fault segments mapping using GIS technique. X.

What can satellite views tell us about Earth’s surface?

NASA’s satellites carry sensors that observe Earth to better understand the environment. These satellite sensors gather information about weather, landforms, oceans, vegetation, land use, and other things. The information is transmitted to computers on Earth.

How do you identify a lineament?

Geological lineaments are first identified and delineated in the google earth, assign orientation of the geological structures (faults, joints, shears, fractures) in google earth (using data from geological surface mapping and borehole data) and then import google image in the CAD tools and verified with the actual …

What is a satellite image in geography?

Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.

What are the characteristics of satellite images?

Spatial resolution.

  • Spectral characteristics.
  • Temporal characteristics.
  • Sensor sensitivity.
  • Program History.
  • Image surface area.
  • Multi-angle capability.
  • Tasking.
  • What is visual image interpretation?

    Visual image interpretation is a first analysis approach to remote sensing imagery. Here, the size, shape, and position of objects as well as the contrast and colour saturation are analysed. The height of objects can be determined by indirect visual analysis.

    How do you interpret imagery?

    In analyzing its imagery, you should examine the poem’s figurative language and see how it complements its tone, mood and theme.

    1. Imagery.
    2. Examine Imagery.
    3. Take Note of the Figurative Language.
    4. Examine the Purpose of the Figurative Language.
    5. Example.

    What is visual interpretation of satellite images?

    The interpretation of satellite imagery and aerial photographs involves the study of various basic characters of an object with reference to spectral bands which is useful in visual analysis. The basic elements are shape, size, pattern, tone, texture, shadows, location, association and resolution.

    What is the importance of log interpretation in geology?

    Also, geologic maps developed from log interpretation help with determining facies relationships and drilling locations. Increasingly, the importance of petrophysics and well- log analysis is becoming more evident as more atten- tion is being devoted to the ongoing management of reservoirs.

    What are geophysical logs?

    Geophysical Logs Interpretation: Geophysical logs are logs created by raising or lowering a set of probes and/or sondes in a well. The probes take continuous or discrete measurements indicating specific lithology and hydrologic properties.

    What are well logs?

    The different sources create records (logs), which contain one or more curves related to some property in the rock surrounding the wellbore (see Society of Professional Well Log Analysts, 1984). For the reader unfamiliar with petrophysical logging, some confusion may develop over the use of the word

    What parameters can be determined from well log measurements?

    The two primary parameters determined from well log measurements are porosity and the fraction of pore space filled with hydrocarbons (i.e., hydrocarbon satu- ration).
