Taking photos of ground -Airborne platform was first form or remote sensing
Edge
Terms used for links of a network
The U-2 aircrafts remote sensing capabilities were especially proven during what?
The Cuban Missile Crisis
What does the Fedirp field refer to in a Tiger 2000 file?
The direction of the prefix of a street
What file shows all the road networks of the U.S.?
Tiger file
UAS
Unmanned Aircraft System-piloted from ground
Junction
Used for nodes (or places where edges come together)
What is special about a GEOpdf file?
You can take off some details shown on a map if you want to look at a specific item of it
standard deviation
a computed measure of how much scores vary around the mean score
quantile
a data classification method that attempts to place an equal number of data values in each class
equal interval
a data classification method that selects class break levels by taking the total span of values and dividing by the number of desired classes
What does a map template provide?
a pre-arranged way of placing elements on a map
nadir
area directly below photo
Dijkstra's algorithm
calculates shortest path between a origin node and other destination nodes
CIR photo
color infrared photo- a photo where infrared reflection is shown in shades of red, red reflection is shown in shades of green, and green reflection is shown in shades of blue
Natural Breaks
data classification method that selects class break levels by finding spaces
DPI
dots per inch (coarse or sharp)
Tiger/line files
file produced by the census bureau that contains other items corresponding to line segments
Visual Hierarchy
how features are displayed on a map to emphasize their level of importance
Aerial Photography was first obtained from an aircraft when and by what?
in 1908, from a wright brothers plane
Site and association
info referring to location of objects and their related attributes in an image used as elements
What is the uniqueness of spatial data?
it can be mapped
Small scale map
large area with little detail
What determines an aerial photo?
lense of camera and height (scale)
map scale
measurement on map and real-world equivalence
Linear interpolation
method used in geocoding to place an address location among a range of addresses

Which of the following data classification methods attempts to place an equal number of data values in each group?
quantities- not equal interval
Geographic scale
real world size or extent of an area
Orthorectification
removes the effects of relief displacement and gives uniform scale
True orthophoto
see as if from directly above photos
Tiff
tagged image file format (graphics)
Principal point
the center point of an aerial photo
Photogrammetry
the process of making measurements using aerial photos
cartographic generalization
the simplification of representing items on a map
