Esri: Basics of Raster Data
Can you find a DRG's spatial reference information by way of inspecting it in ArcMap? -
ANS-Yes, by using examining the Source tab within the Layer Properties dialog box.
Data compiled for which of the subsequent scales is possibly to be the maximum particular? -
ANS-1:1000
How many unique reflectance values may be stored in an eight-bit photo? - ANS-x 24
x8
In ArcGIS, how are you going to assign a coordinate system to a raster with an undefined
spatial reference? - ANS-Open the raster records houses and edit the spatial reference
alternatives to assign the coordinate machine.
In the ArcMap desk of contents, which of the subsequent could you operate to determine the
data supply of a layer? - ANS-List By Source button
TRUE or FALSE: Although it covers most effective one-fourth of the land vicinity of a DRG, a
DOQ calls for 3 to 11 times as plenty virtual garage space. - ANS-True
TRUE or FALSE: Scale varies in vertical aerial pics, however is uniform in orthophotos. -
ANS-True
What characteristic is associated with every factor area in a DEM? - ANS-Elevation
What does the scale of the raster indicate? - ANS-
What is one ability advantage of satellite tv for pc far flung sensing over aerial images? -
ANS-Global insurance
What is spatial resolution? - ANS-A measure of the smallest object that a far off-sensing device
can come across
What is the bit intensity of an picture? - ANS-The wide variety of binary integers that may be
stores for every pixel
Which of the following an be used as a basemap? - ANS-Scanned map
Which of the subsequent is applicable to the cellular length of a raster? - ANS-Cell size
influences the accuracy with which geographic features can be represented.
