flying over moving vehicles
flying over people without their consent
flying beyond full view of the operator - ANSWER-flying over moderate to large sized
water bodies
Why are UAS programmed to collect imagery of large areas with significant overlap
between each image?
so that a seamless mosaic of the area can be created
so that images can be orthorectified as oblique views

with:
Dijkstra's Algorithm
Network Junctions
Address Standardization
Impedance Values - ANSWER-Dijkstra's Algorithm
If an address is matched to the correct street segment but the wrong location on that
street, the problem could be:
The reference database does not contain the proper zip code information
The address ranges in the reference database do not match the actual street address
ranges in the real world
The linear interpolation algorithm used in the process is out of date
, The street address was parsed incorrectly - ANSWER-he address ranges in the
reference database do not match the actual street address ranges in the real world
In order to match an address to a particular street location, what fields are necessary to
have in the reference database?
The number of houses on the street
The address ranges on the right and left side of the street
The city name and zip code of the street address
The type of address (whether residential, commercial, or industrial) - ANSWER-The
address ranges on the right and left side of the street
A major road (such as Virginia Beach Blvd) would be represented in a GIS as:
A single record
Multiple records, with each representing one piece of the road
Two records, each representing half of the road's distance
One file entitled "FENAME = 'Virginia Beach Blvd'" - ANSWER-Multiple records, with
each representing one piece of the road
The tool used for viewing imagery at a particular location on a road is:
Transit View
Geocoding Vis
Street View
Road Visualizer - ANSWER-Street View
The base network data used for geocoding is referred to as:
Reference database
Street View
