Why is the sky blue? Rayleigh scattering occurs when light interacts with particles that are _____ than the wavelength of light

smaller

100

This type of geospatial data stores spatial information in the form of an image made up of pixels representing a single value

Raster

100

An array of these makes up a sensor

Detectors

100

This is an image from a GOES satellite, which continually collects data from the same point on Earth in this kind of orbit


Geostationary

100

Make one of these using the following button: 

Spectral Profile Tool

200

This kind of EMR, which ranges from .720 to 1.3 microns, is highly reflective in healthy vegetation 

NIR

200

A raster is made up of two components: image data and this

Header 

200

This type of sensor detects and records EMR emitted from the sensor itself, like LIDAR or RADAR

Active sensor

200

This Earth observation program is the longest running satellite continuity program, with its first launch in 1979

Landsat

200

What land cover type does this spectral signature represent? 

Soil/barren

300

This part of the EMS is usually emitted from a surface, not reflected (wavelengths not needed, just the name)

Thermal infrared

300

To create a false color composite from Landsat imagery displays NIR-RED-GREEN in the RGB channels, use this band combination 

5-4-3

300

In a satellite image, the total cross-track and along-track widths for the entire sensor define this characteristic

Spatial extent

300

This medium to coarse resolution program has a wide swath width so that it can provide daily data of the entire globe for monitoring ocean temperatures, vegetation health, land cover change and snow and ice cover.

MODIS

300

The SCP Plugin in QGIS converts this number to a reflectance value. 

Digital number

400

This value is the ratio of the observed brightness reflected off of a surface to the amount of irradiance falling on it  - also denoted as  p(λ) = RR(λ) / RI(λ)

reflectance

400

A GIS can plot raster data in the correct place on Earth because of these pieces of information in the header (name two) 

Top left coordinate, pixel size, CRS

400

A sensor that produces this spectral profile is probably in this spectral resolution category



Hyperspectral

400

On a satellite's elliptical orbit, this is the point the satellite is closest to earth 

Perigee

400

This file extension is how QGIS default saves projects and data

.gpkg

500

Shown here, the relationship between temperature of a blackbody, emitted radiation and wavelength is known as this law


Wien's displacement law

500

This is how multi-band imagery is digitally organized into a single file 

Interleave

500

This part of the sensor response curve, covered by the red box, is above the maximum of the sensor's dynamic range

Saturation

500

This spaceborne-LIDAR system recently went through a test mission aboard the ISS, and captures near-global canopy information in full waveform format

GEDI

500

Oops! What's happening on the left is likely this kind of error(

Projection

600

This type of surface is a perfect isotropic reflector

Lambertian

600

This is the maximum value that can be stored in an 8-bit unsigned integer raster

255

600

One way sensors differentiate specific wavelengths is by using filters. This second type is more often used in hyperspectral sensors

Diffraction grating 

600

This image is from this satellite program, which has 10 bands in the shortwave to thermal infrared range:

ASTER

600

Like QGIS, this is another example of an open source GIS platform

GRASS R Python GDAL  etc
