ArcGIS Pro Associate key terms

A container for spatial and attribute data stored in a structured format, either as files in a folder (file geodatabase) or inside a relational database. It supports feature classes, tables, relationship classes, and domains.

A collection of features of the same geometry type (point, line, polygon, or multipoint) stored together with a common set of attribute fields, usually inside a geodatabase or as a shapefile layer.

A legacy Esri vector data format made of several companion files (.shp, .shx, .dbf, .prj) stored in one folder. It holds one geometry type and has field-name and size limits.

A tabular view of the records in a feature class or standalone table, where each row represents a feature and each column represents a field holding a value for that feature.

A column in an attribute table that stores one type of information for every record, such as a name, a measurement, or a date. Fields have a defined data type and optional properties.

A rule attached to a field that restricts the values a user may enter, either as a list of allowed values (coded value domain) or as a permitted numeric range (range domain).

A way to group the features in a single feature class into categories that behave differently, each with its own default values and domain assignments, while remaining stored in one dataset.

A geodatabase object that defines and stores an association between features in two tables or feature classes, such as one parcel having many owners, with rules about cardinality.

The framework of parameters that defines how locations are measured and where data sits on the earth, including geographic systems using degrees and projected systems using linear units.

A mathematical method for transferring locations from the curved earth surface onto a flat map, always introducing some distortion in shape, area, distance, or direction.

A coordinate system that locates positions on the earth using angular units such as degrees of latitude and longitude, referenced to a datum and an ellipsoid.

Descriptive information stored with a dataset that documents its source, purpose, accuracy, currency, contact, and access constraints, helping others judge whether the data fits their use.

An alternative display name assigned to a field or table so that users see a friendly, readable label instead of the underlying short database name.

A subset of features or records marked as active so that operations apply only to them; selections can come from clicking, a query, or a location-based rule.

A stored SQL filter on a layer that limits which features are drawn and available, letting one dataset appear as several focused layers in a map.

A reference in a map or scene to a data source, together with display settings such as symbology, labeling, transparency, and visibility range, without duplicating the source data.

The rules that control how features are drawn, such as single symbol, unique values, graduated colors, graduated symbols, or charts, chosen to reveal patterns in the data.

The rule used to divide numeric values into classes for graduated symbology, for example equal interval, quantile, natural breaks, or standard deviation.

Dividing a numeric field by another value, such as a total or an area, so that map symbols compare rates or ratios instead of raw counts that mostly reflect size.

The automatic placement of text derived from feature attributes on a map, governed by label classes, expressions, placement rules, and conflict resolution settings.

Text stored as features with their own positions and symbology, rather than generated on the fly, so that individual labels can be edited and placed by hand.

A 2D document in a project that holds layers, a coordinate system, and layout-independent display settings, used for viewing, editing, and analysis.

A 3D document in a project that displays layers in a global or local perspective, supporting elevation surfaces, extruded features, and camera navigation.

A page-based document that arranges one or more maps, plus elements such as legends, scale bars, north arrows, and text, for printing or exporting.

A layout element that contains a map or scene and controls its extent, scale, rotation, and clipping on the page.

The file that organizes all related work in ArcGIS Pro, including maps, scenes, layouts, tables, toolboxes, and database connections, stored together in one folder.

A packaged operation that takes input data, applies a defined process such as overlay, buffer, or conversion, and writes output data, run from a tool dialog or script.

A container that holds geoprocessing tools, models, and scripts, either supplied with the software or created by users to organize custom workflows.

A visual diagramming environment for chaining geoprocessing tools so that the output of one tool feeds the next, creating a reusable and shareable workflow.

Settings that control how a tool runs, such as output coordinate system, extent, cell size, workspace, and tolerance, applied to tools in a session or model.

A geoprocessing operation that creates polygons at a specified distance around input features, optionally dissolving overlaps, used for proximity and exclusion analysis.

Combining two layers spatially so that attributes and geometry are merged, for example intersect, union, or spatial join, to reveal where conditions coincide.

A tool that appends attributes from one layer to another based on their spatial relationship, such as within, intersect, or nearest, without changing geometry by default.

A geoprocessing operation that cuts input features down to the area covered by a boundary polygon, keeping only the portion inside and preserving the original attributes.

A tool that merges features sharing the same value in chosen fields into single features, often used to remove boundaries between adjacent polygons of one category.

A map stored online in a portal that references web layers and defines their display, extent, and pop-ups, viewable in browsers and mobile apps and reusable across the platform.

A hosted or referenced layer published to a portal that serves features, tiles, or imagery over the web for use in maps, apps, and field workflows.

An online organizational or public site, such as ArcGIS Online, that stores, manages, and shares maps, layers, apps, and other items among users and groups.

Setting the access level of an item so that it is private, shared with specified groups, shared with the whole organization, or available to everyone publicly.

The title, summary, tags, description, and credits attached to a portal item, which help others find it and understand its purpose, limitations, and proper use.
