Remote Sensing Review Crossword

The science and art of obtaining information about an object by a device that is not in contact with the object.
In remote sensing, objects/features on the surface of Earth interact with _______ radiation.
Wavelength is the distance between adjacent ______ .
Frequency is how many _______ pass by in a unit of time and is measured in Hertz..
Wavelength and frequency are _________ proportional.
The product of wavelength and frequency is _______.
Compared to radio waves, gamma rays have ______ frequency.
The type of region that spans from 400 - 700 nm.
________ radiation spans from 700nm- 1mm and is invisible to human eyes.
The remainder of incoming radiation that reaches the earths surface is: transmitted, reflected, or ________.
This region of EMR is responsible for probing cell structure (including cell size, number of cells and number of inter cell spaces).
This type of infrared can tell you about the water content in leaves.
________ status determines its interaction with EMR.
These objects record the amount of EMR reaching it.
The Sun is an example of one of these types of sensors.
These types of sensors provide their own source of EMR and records subsequent interactions.
Where the sensor is mounted.
These types of satellites orbit from north to south or south to north and many are sun-synchronous.
Satellites that orbit at altitudes above 35,000 km and revolve at speeds matching Earth's rotation are said to be in this type of orbit.
Raster or grid format uses these squares to store information.
This dictates what features can be seen in remotely sensed data.
This type of resolution decides the size of the smallest object on the ground that can be distinguished in the image.
This type of resolution involves the ability to resolve features in the EM spectrum.
This type of resolution involves the time lag between two subsequent data acquisitions for the same area.
The type of resolution that is related to the values used for storing reflected EMR values.
The area of the Earth which is images during a satellite orbit is referred to as the satellite's _______.
This type of satellite sensor has a rotating mirror.
This satellite sensor is also called 'along track' and has a lens system.
This is the simplest vegetation index and is defined as: NIR - Red. One disadvantage of this index is that different combinations of pixel values can produce same values.
This index (hint:NIR/Red) is high for vegetation and low for soil, ice, water, etc.
(NIR-Red)/(NIR+Red) = _______
This data type distinguishes one entity from another (ex. house numbers on a street).
In this data type values follow the same order (ex. below average, average, above average).
Values in this data type have exact differences between them (ex. temperature on a Celsius scale).
in this data type values have exact differences between them and there is an absolute zero (ex. Kelvin, weight, height, duration)
This type of data type has a direction (ex. longitude, months, compass direction)
An example of this type of classification is when a forester wants to divide burn sites into 4 categories: high, medium, low and no burn.
This type of classification used clustering, where similar features will have similar reflectance values.
This assessment can tell you how thematic classes in the processed image matches with the actual classes on the ground.
This table compares classes in the image to classes on the ground.
A contingency table is also called a what?
This accuracy is the number of correctly classified points over total number of points.
The number of classified points over row total for that class is this type of accuracy.
The error when something was failed to be correctly classified.
______ error = 100% - User accuracy (%).
Thematic classes are ____ detailed.
