  1. Remote Sensing 2012 SUMMER INSTITUTE

  2. Presented by: Mark A. Van Hecke National Science OlympiadEarth-Space Science Event Chair Roy Highberg North Carolina Science OlympiadRemote Sensing National Event Supervisor

  3. DISCLAIMER: This presentation was prepared using draft rules. There may be some changes in the final copy of the rules. The rules for this event that are in the current year’s Coaches Manual and Student manuals will be the official event rules.

  4. Presentation Objectives: • Provide 2012 Summer Institute Participants with an overview of 2013 Remote Sensing Rules and proposed change to Geologic Mapping in 2014 • Provide 2012 Summer Institute Participants with an overview of 2013 Remote Sensing Event Topic Areas and training strategies to use with students.

  5. 2013 Event Overview The 2013 Remote Sensing event will continue its emphasis on Earth’s Hydrosphere The role of water in maintaining the radiative balance of Earth’s atmosphere Hydrologic cycles Local and global ecological effects of changes in atmospheric and oceanic temperatures

  6. 2014 Event Overview In 2014, Geologic Mapping will be cycled into the Earth/Space Science Event Rotation to replace Remote Sensing

  7. EVENT DESCRIPTION: Remote sensing technologies are used to record data and monitor changes in the atmosphere and oceans by acquiring radiometric measurements of: • Atmospheric and ocean temperature • Greenhouse gases • Changes in land/sea/ice elevations • Changes in land/sea vegetative cover

  8. WHAT STUDENTS WILL DO: Students will be presented with one or more tasks requiring the use of science process skills to complete tasks related to the study of remote sensing and including: • Describe interactions between electromagnetic energy and the atmosphere, oceans and earth • Identify and describe significant Earth Observation Missions related to climate change and land use • Using remote sensing imagery to describe local and global changes in atmospheric and ocean temperatures, hydrologic cycles and vegetative cover

  9. Activity One: Data Interpretation In this activity, you will learn how to read a remote sensing image and understand its: General Features Hydrologic Features

  10. Data Interpretation Data interpretation in remote sensing is the process of detection, identification, description and the assessment of features found in images.

  11. Data Interpretation The basic elements of data interpretation include: Location Tone Scale Texture Shape Shadow Pattern Association

  12. Data Interpretation: Location Knowing where a remote sensing image was acquired can provide us with clues about the relationship of an identified feature to other features shown on the image….. In the images that follow, check off those words on your worksheet that describe the location of this image….

  15. Data Interpretation: Scale Scale represents the ratio of distance on a map or remote sensing image to actual ground distance…. In the images that follow, check off those words on your worksheet that provide the scale of this image….

  26. Data Interpretation: Tone Tone refers to the brightness of an object. Tone may also be used to describe gradual change such as foliage or elevation. In the images that follow, check off those words on your worksheet that provide information about the tone of this image….

  29. Data Interpretation: Texture Texture is used to refer to how the patterns and tones of a remote sensing image interact with one another. Texture is often expressed as adjectives such as flat, rough, blotchy, glossy, solid, etc. In the images that follow, check off those words on your worksheet that provide information about the tone of this image….

  34. Data Interpretation: Shadow Shadows are produced by the angle of the Sun and the angle of the equipment used to record the image at the time it is taken. Shadows can be used to determine the height of objects in remote sensing images In the images that follow, check off those words on your worksheet that provide information related to shadows in this image….

  37. Data Interpretation: Association Association describes the relationship between a recognizable object and unrecognizable objects. In the images that follow, check off those words on your worksheet that provide information about associations between objects in this image….

  41. 2013 Key Event Topic Areas: 2013 Key Event Topics for Remote Sensing include: Light and the Electromagnetic Spectrum Map and Image Reading Skills The Hydrosphere Remote Sensing Technologies

  42. Activity Two: Recall that light energy, like other forms of energy travels in waves. The ‘color’ of light is determined by the wavelength of the light… Reading EMS Wavelengths In Remote Sensing Images
