Data Models
The data model associated with Field View
Raster
Shapefiles use this data structure, where polygons are composed of lists of coordinates for vertices
Spaghetti data model
Each column or field in an attribute table contains this
One attribute and its values for all features
Geocoding a table with addresses requires this type of dataset
Locator
A way to select features in one layer that have a particular spatial relationship to features in another layer
Location query or select by location
Matching attribute values for each dataset
A vector geometry with 1 spatial dimension
Line
A line segment connecting two nodes in topological data
Arc
Two formatting rules for shapefile field names
10 characters or less, no spaces or special characters, must not start with a number
A tool in ArcGIS Pro that allows you to create point features from table data with latitude and longitude coordinate columns
Display XY Data
Spatial predicate
Two formatting requirements for a table to join it to a feature class
One row per feature, one header row, column headers formatted as shapefile field names, remove useless rows, foreign key with same data type and matching values as a feature class field
The name for a vector object, an instance of a class
Feature
In a raster, this type of resolution is determined by ground sample distance, or the width of each pixel in ground units
Spatial resolution
A number with decimals, such as 1.234, can be entered in a field with this data type
Float or double
Use snapping
The clause of a SQL expression that is primarily used for attribute queries in GIS
WHERE clause
A proportional symbol map uses this visual variable to represent numerical data
Size
The basic component of a raster dataset that holds a single value
Pixel or cell
A lake with an island in it can be represented as a polygon with one each of these rings
Outer ring, inner ring
A domain controls this
The possible attribute values for a given field
For georeferencing, this type of transformation is also known as "rubber-sheeting" because it warps different parts of the image to fit an equation
Second-order polynomial
Logical operator that selects features that meet all of the criteria in the expression
AND
A choropleth classification must use this type of data values to avoid becoming a population map
Normalized
A type of lossless compression that can be used with GeoTIFF files
LZW
Vector geometries with UTM Easting and Northing coordinates use this type of CRS
Projected Coordinate System (PCS)
For numerical fields, precision controls this
The number of possible digits in the value
A set of rules for vector geometries that flag digitizing errors
Topology
What to do when you want a layer that includes only some of the features in a feature class
Select and export features or create layer from selection
A spatial join does this
Copies attribute values from join features that match target features with a specified spatial relationship to the output target feature class attribute table
