GISP - FINAL TERMS TO STUDY
Zonal Statistics (Raster Overlay Tool) - ANSWER-Summarizes values in a raster layer
by zones (categories) in another layer—for example, calculate the mean elevation for
each vegetation category
Combine (Raster Overlay Tool) - ANSWER-Assigns a value to each cell in the output
layer based on unique combinations of values from several input layers.
Raster Overlay Tools - ANSWER-Zonal Statistics, Combine, Single Output Map
Algebra, Weighted Overlay, Weighted Sum
Single Output Map Algebra (Raster Overlay Tool) - ANSWER-lets you combine multiple
raster layers using an expression you enter - ex. you can add several ranked layers to
create an overall ranking
weighted overlay (Raster Overlay Tool) - ANSWER-automates the raster overlay
process and lets you assign weights to each layer before adding (you can also specify
equal influence to create an unweighted overlay)
Weighted Sum (Raster Overlay Tool) - ANSWER-overlays several rasters multiplying
each by their given weight and summing them together
Join - ANSWER-combine two attribute tables into one using a common key between
tables
Merge - ANSWER-combines multiple input datasets of the same data type into a single
new output
Append - ANSWER-combines datasets of the same data type into an existing dataset
Union - ANSWER-Combines input features with another feature dataset
Clip - ANSWER-Extracts input features that overlay the clip features (keeps inputs
attributes)
Intersect - ANSWER-extracts features which overlap in all layers to new feature class
(joins attribute tables)
less accurate - ANSWER-Generalization will cause data to be...
Small Scale - ANSWER-Generalization is typically used for what scale maps?
, INSPIRE Metadata Directive Metadata - ANSWER-This style lets you view and edit a
complete ISO 19139 metadata document that adheres to the INSPIRE Implementing
Rules, export metadata in the ISO 19139 format, and validate it using the ISO 19139
XML Schemas.
Item Description metadata style - ANSWER-lets you see and edit a simple set of
metadata properties for an item. Only one page of information is available when editing
metadata with this style. This style is designed to facilitate providing information that is
used by ArcGIS; it is indexed and available for searching and can be published with the
item to ArcGIS Online.
metadata standard - ANSWER-a document identifying content that should be provided
to describe geospatial resources such as maps, map services, vector data, imagery,
and even nonspatial resources such as tables and tools that are relevant to your spatial
work.
Generalization - ANSWER-Selection, removing detail, simplification, dissolve/merge,
aggregation and exaggeration are all types of...
Aggregating zones of data - ANSWER-Nibble, shrink, expand, region group and thin are
all examples of what type of generalization?
Smoothing data edges - ANSWER-Boundary Clean and Majority Filter are all examples
of what type of generalization?
Aggregate - ANSWER-reducing the resolution of a raster (generalization)
Map Algebra - ANSWER-involves doing math with maps.
Raster - ANSWER-Map Algebra only applies to what kind of GIS?
local, focal, zonal, and global - ANSWER-Types of Map Algebra
Map Algebra - ANSWER-local, focal, zonal and global are different types of what?
Local Operations (Map Algebra) - ANSWER-The simplest approach is map algebra on a
cell-by-cell basis. For example, you have 2 rasters stacked on top of each other. Then,
you add each cell one-by-one.
If raster cells represent temperature, you can subtract them both at different time
periods. You can find the difference in temperature for each cell.
