A satellite image is made up of thousands of tiny dots called what?
The tiny dots in a satellite image are called pixels. Each pixel represents a specific color or brightness level and together they form the image that we see.
What is image space and feature space in remote sensing?
The image space is the 2D plane of the image where pixels are located. It represents the spatial space of the image. In other words, when we talk about the location of each pixel in an image, we are talking about image space. On the other hand, feature space is about the radiometric values assigned to each pixel. In case of a grey-scale imagery, only one radiometric value is assigned to each pixel. When we say an image is RGB or multispectral, then each pixel has several radiometric values that are stored in different channels (for instance there are 3 channels of Red, Green and Blue in an RGB image, so for a pixel we have 3 radiometric values). Feature Space is the space of these radiometric values; the radiometric values of each pixel can be plotted in that space and you can create a feature space image. Last example, an RGB image has a 3 dimensional feature space while it still has a 2D image space.
When satellite image is analyzed a unit called pixel is key to calculating what?
When analyzing satellite images, a pixel represents the smallest unit of information in the image. It contains data about the color, intensity, and other characteristics of a specific location on the Earth's surface. By calculating the values stored in each pixel, it is possible to extract information about land cover, land use, and environmental changes.
How do pixels make up a satellite image?
A satellite image is made up of pixels, which are tiny square elements that form a grid to represent the image. Each pixel contains digital information about color and brightness, and when combined, they create the overall visual representation of the Earth's surface as captured by the satellite sensor. The resolution of a satellite image is determined by the size of these pixels, with higher resolution images having smaller pixels and capturing more detail.
When do the suns rays strike latitude 23.5 at an angle of 90 degrees?
Actually at 23.5 degrees it is never overhead because the Earth's axial tilt is only 23.44 degrees. However, for the purposes of this answer let us round up to 23.5 degrees. The Tropic of Cancer is located at 23.5° North of the equator. The Tropic of Capricorn lies at 23.5° South of the equator. There is one day each year when the Sun is overhead (90 degrees) at these latitudes. In the North this is at the Summer Solstice in June (around the 21st) each year and in the South it is at the Winter Solstice in December (around the 21st) each year.
Clicks Rotate Right on the Drawing toolbar twice how many degrees will her image rotate?
Clicking "Rotate Right" on the Drawing toolbar typically rotates an image by 15 degrees each time. Therefore, if you click it twice, the image will rotate a total of 30 degrees to the right.
How many degrees of the sky does each zodiac represent?
Each zodiac represents 30 degrees in the sky. The Ancient Egyptians recognized the precession of the Equinox where the equinox changes sign every 2160 years, e.g from the Age of the Aries to Pisces.
What is angle at 910?
On the clock each minute represents 6 degrees and so 10 minutes is 60 degrees and 25 minutes is 150 degrees
What does bitmap mean?
A bitmap is a series of bits which represents a rasterized graphic image, each pixel being represented as a group of bits.
What parameters do 24 and 2 represent in M24X2 represent respectively?
M24 represents the outside diameter(O.D.) of the threads and the 2 represents the pitch of the threads(the distance between each thread).
How many degrees is each quadrant?
Each quadrant of a Cartesian coordinate system represents a 90-degree section of the 360-degree circle. Therefore, the first quadrant spans from 0 to 90 degrees, the second from 90 to 180 degrees, the third from 180 to 270 degrees, and the fourth from 270 to 360 degrees.
What is diameter of circle if radius is 1.5?
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
A satellite image is made up of thousands of tiny dots called what?
The tiny dots in a satellite image are called pixels. Each pixel represents a specific color or brightness level and together they form the image that we see.
What is the answer to the microtype puzzle with a crow an inn sign and a hand?
The answer to the microtype puzzle with a crow, inn sign, and hand is "Blackjack." Each image represents a word that, when combined, forms the answer. The crow represents "black," the inn sign represents "jack," and the hand represents "hand."
How do you figure to make a hexagon. I have landscape timbers that I want to make a hexagon. The diameter will be 7.5'. How long would each timber be and what angle of cut of each timber?
angles should be 60 degrees 360/6 degrees of circle divided by 6 sides length of timber should be the radius or half the diameter 7.5/2 = 3.75'
What is the area of the shaded sector if the circle has a diameter of 8.5cm and two angles measuring 160 degrees each?
shaded sectors do not appear on listings
Do two radii make a diameter?
Only if they are placed in such a way as to make a straight line ,i.e., they should be placed at 180 degrees to each other.
