12) Proximity Analysis Flashcards
(26 cards)
________ is designed to examine spatial distribution relationships between datasets.
Proximity Analysis
One way of analyzing locations of features is by ________.
measuring the distance between them and other features in the area
FEATURE-BASED PROXIMITY TOOLS
- The Buffer Tool
- The Near Tool
- The Point Distance Tool
- The Create Thiessen Polygon Tool
- The Select Layer By Location Tool
- The Closest Facility Tool
- The Service Area Tool
________ is usually used to delineate protected zones around features or to show areas of influence.
The Buffer Tool
________ creates area features at a specified distance (or several specified distances) around the input features.
The Buffer Tool
________ calculates the distance from each point in one feature class to the nearest point or line feature in another class.
The Near Tool
________ can be used to find the closest stream for a set of wildlife observations or the closest bus stops to a set of tourist destinations.
The Near Tool
________ calculates the distance from each point in one feature class to all the points within a given search radius in another class.
The Point Distance Tool
________ creates polygon features that divide the available space and allocate it to the nearest point feature.
The Create Thiessen Polygon Tool
________ are sometimes used
instead of interpolation to generalize a set of sample measurements to areas closest to them.
Thiessen polygons
Finding features in one layer that are within a given distance of (or share one of several other spatial relationships with) features in another feature class or layer.
The Select Layer By Location Tool
________ is a route solution which finds locations on a network that are closest (in terms of route distance) to an origin.
The Closest Facility Tool
________ is a region that encompasses
all accessible streets (that is, streets that are within a specified impedance).
The Service Area Tool
RASTER-BASED PROXIMITY TOOLS
- The Euclidean Distance Tool
- The Euclidean Allocation Tool
- The Euclidean Direction Tool
- The Cost Distance Tool
- The Cost Allocation Tool
- The Path Distance Allocation Tool
- The Corridor Tool
- The Surface Length Tool
________ calculates, for each cell, the distance to the closest source.
The Euclidean Distance Tool
________ is a straight line distance where the minimum distance to a feature is calculated for every cell.
The Euclidean Distance Tool
________ divides an area up and allocates each cell to the nearest input feature.
The Euclidean Allocation Tool
________ creates polygonal raster zones that show the locations that are closest to a given point.
The Euclidean Allocation Tool
________ gives each cell a value that indicates the direction of the nearest input feature.
The Euclidean Direction Tool
________ calculates the distance to the nearest source for each cell, minimizing cost specified in a cost surface.
The Cost Distance Tool
________ takes into account that distance can also be measured in cost and that travel can vary with terrain, ground cover, or other factors.
The Cost Distance Tool
________ gives each cell the identifier of
the closest source, minimizing cost specified in a cost surface.
The Cost Allocation Tool
________ extends the cost distance tools allowing the use of a cost raster, and at the same time, takes into account the additional distance traveled when moving over hills, cost of moving up or down various slopes, and an additional horizontal cost factor in the analysis.
The Path Distance Allocation Tool
________ calculates the sum of accumulative costs for two input cost distance rasters.
The Corridor Tool
