32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Feature class vs shapefile

A feature class lives in a geodatabase and supports domains, subtypes, and relationship classes; a shapefile is a folder of files without those capabilities and with 10-character field names.

Define vs project

Define Projection assigns a coordinate system to data that lacks one without changing coordinates; Project transforms coordinates into a new coordinate system and creates a new dataset.

Coded value domain

A geodatabase rule listing valid values and their descriptions for a field, restricting attribute entry to that list. It applies only to geodatabase feature classes and tables.

Subtype

A geodatabase property that groups features in one feature class by an integer code stored in a subtype field, allowing different default values, domains, and rules per group.

Feature dataset purpose

A container in a geodatabase holding feature classes that share a coordinate system. Required for building topologies, geometric networks, and network datasets.

Attribute join persistence

An attribute join matches records by a common field and is stored in the map only; the source data is not modified. Export to make it permanent.

Text field length

The maximum character count for a text field, set when the field is created. It cannot be changed in place; add a new field and calculate to alter it.

File geodatabase size limit

The default maximum size for a feature class in a file geodatabase is 1 TB. Enterprise geodatabases scale with the underlying database management system.

Map vs layout

A map is a container of layers with a coordinate system for viewing and analysis; a layout is a separate page holding map frames, legends, and text for printing or export.

Quantile classification

A graduated symbology method assigning an equal number of features to each class. Useful for evenly distributed display but can split similar values across classes.

Natural breaks classification

The Jenks method places class breaks where gaps between values are largest, minimizing within-class variance. Best when data clusters naturally.

Normalizing a field

Dividing a numeric field by another field, a log, or percent of total so counts from areas of different size can be compared fairly on a map.

Definition query

A SQL filter on a layer that limits which features are drawn and available to analysis. It persists in the map until removed.

Labels vs annotation

Labels are generated dynamically from attributes and reposition as the map changes; annotation is stored text geometry that stays where placed and can be edited individually.

Symbol level drawing

A feature layer option that controls the draw order of symbol classes within one layer, so, for example, highways render above local roads.

Map frame properties

Settings on a layout's map frame controlling which map it shows, its scale, extent, rotation, and clipping. Each frame references one map.

Intersect tool

An overlay tool that keeps only the portions of features overlapping all input layers and combines their attributes into the output feature class.

Clip tool

An overlay tool that cuts input features to the boundary of a clip layer, preserving the input attributes but not adding the clip layer's attributes.

Union tool

An overlay tool that combines all areas of two or more polygon layers into one output, retaining attributes from every input across the combined geometry.

Spatial Join tool

A tool that appends attributes from one layer to another based on a spatial relationship such as intersects or within, writing results to a new feature class.

Near tool

A proximity tool that adds the distance and feature identifier of the closest feature in another layer to the input features, modifying the input in place.

Select Layer By Location

A tool that selects features based on a spatial relationship (intersects, within, contains, crosses) to features in another layer, honoring the current selection method.

ModelBuilder parameters

Model variables marked as parameters become inputs or outputs when the model runs as a tool, letting users supply values at run time.

Snap raster environment

A setting aligning output raster cells to the cell grid of a reference raster, preventing misalignment when combining raster datasets in analysis.

Zonal Statistics

A tool summarizing raster cell values within zone polygons, producing statistics such as mean, sum, or maximum per zone as a raster or table.

Geoprocessing environments

Settings such as workspace, output coordinate system, extent, cell size, and mask that control how tools produce outputs. They can be set at project, map, or tool level.

Web map definition

A JSON document stored in ArcGIS Online or Portal that references layers and settings for display; it holds no data itself, only references to web layers.

Feature vs tile layer

A hosted feature layer serves vector data and supports editing and queries; a tile layer serves pre-rendered images for fast display but cannot be edited.

Sharing levels

Items can be shared with the organization, specific groups, or everyone (public). The chosen level determines who can find and open the item.

Project package

A .ppkx file bundling a project's maps, layers, and optionally the source data so it can be opened on another machine or shared with another organization.

Item properties for discovery

Title, tags, summary, description, and thumbnail attached to a shared item; they drive search results and how the item appears to other users.

Offline map use

A map enabled for offline use can be downloaded with its layers so field workers can view and edit without a network connection, then synchronize later.
