Vector Data and Analysis
This type of feature serves as a building block for all spatial vector data.
What is a point?
This type of raster has values that represent different classes.
What is an integer grid?
Density analysis and interpolation both use this type of data as an input.
What is vector data?
This type of operation operates on each cell of a raster individually.
What is a local operation?
The horizontal distance from one cell to another used in raster distance calculations.
What is 1?
This vector-based map manipulation technique has a "cookie-cutter" type effect on feature geometries.
What is clip?
This type of raster grid does not have a value attribute table.
What is a floating point grid?
Both density analysis and interpolation produce this type of data as an output.
What is gridded (raster) data?
What is neighborhood (or focal) operations?
In order to calculate the euclidean distance from locations in a raster you should reclassify your input location raster to a binary raster with values of 1 and this value.
What is NoData (or Null)?
This general type of spatial relationship defines how near or far features are from other features.
What is proximity?
This feature of a raster dataset is defined by the dimensions of a grid cell.
What is resolution (or spatial grain)?
This technique is used to estimate unknown values for locations where values have not been measured given a set of input points with known values.
What is interpolation?
This type of raster operation can be useful for aggregating gridded information to larger scalar units such as counties.
What are zonal operations?
This process can be likened to peeling an orange and trying to lay the peel flat.
What is projection?
This tool can be used to describe how populations have shifted over time.
What is mean center (or weighted mean center)?
The value attribute table includes these items.
What is value and count?
This type of interpolation technique does not require estimated value to match exactly with measured values at measurement locations.
What is approximate?
This raster operation calculates the distance of all locations on a surface from an input location/locations.
What is euclidean distance?
These types of spatial operations should be used when your problem statement uses words such as "near", "close", or "within 100 feet".
What are proximity operations?
The extent of this layer is preserved when using an identity overlay.
What is the input layer?
These quintessential raster datasets are used to represent the topography of the land as a continuous surface.
What are digital elevation models (DEMs)?
This interpolation technique is an explicit representation of the first law of geography.
What is Inverse Distance Weighted (IDW)?
These two tools can be used to create a binary raster of 1s and 0s representing the presence of forest cover from a landcover dataset.
What are Raster Calculator and Con?
These types of GIS models can be used to evaluate multiple characteristics of a location using a ranking system.
What are index (or suitability) models?
