Spatial Data
This type of coordinate system can be defined as a 3 dimensional global reference system for defining locations on the surface of the Earth.
What is a geographic coordinate system (GCS)?
This tool allows you to identify features with a specific characteristic.
What is select by attributes?
This tool can be used to identify spatial features that overlap with another set of spatial features.
What is select by location?
When you have multiple points that fall within a single polygon boundary and you need to summarize/aggregate the information from those points you might want to use this tool.
What is a spatial join?
This property of the Earth can create some complications when trying to analyze spatial data or create accurate maps.
What is 3 dimensional (3D)?
These are the units in which locations, in terms of latitude and longitude, are measured in a GCS.
What are degrees?
When performing a table join in ArcGIS this file typically serves as the destination table.
What is a shapefile?
This type of general spatial relationship only identifies features that enclose an object in another layer.
What is containment?
You can use this map manipulation tool to change the shape and extent of an existing spatial layer based on another layer.
What is clip?
All features in this spatial data model/structure are composed of simple x-y coordinate pairs.
What is vector data?
This type of coordinate system is defined by a flat surface where lengths, angles, and areas have constant intervals.
What is a projected coordinate system (PCS)?
This is the cardinality of the join when adding a table with a limited set of information that can describe multiple features to a larger shapefile attribute table.
What is many-to-one?
This type of operation is commonly used to evaluate proximity of one set of spatial features to another.
What is a buffer?
This geographic distribution metric can be used to show how populations have moved over time.
What is mean center (weighted)?
This is often referred to as an automated system for the capture, storage, retrieval, analysis, and display of spatial data.
What is GIS?
This famous map projection which maintains lines of direction was historically used to help sailors cross the Atlantic Ocean.
What is the Mercator projection?
When the cardinality between two tables is one-to-many or many-to-many you may want to use this operation.
What is a relate?
This type of overlay operation only works when the two spatial layers considered are both polygons.
What is a union?
This spatial pattern metric measures how objects are clustered, or not, across space.
What is average nearest neighbor?
This common file format used for spatial data actually includes at least 3 separate files.
What is a shapefile?
These types of map projections maintain the shape of small areas.
What are conformal projections?
These are the terms used to refer to individual rows (or spatial objects) and individual columns in a table, respectively.
What are records (features) and fields (attributes)?
This type of overlay does not change the geometries of the original spatial layer.
What is a spatial join?
This is a common metric used to assess to what extent things that are closer tend to be more like each other than things that are far away.
What is Moran's I?
