Features and graphics

FeaturesA feature is a single record, also known as a row, that represents a real-world entity. It typically contains a geometry (point, multipoint, polyline, or polygon) and attributes but it can also contain just attributes.Learn more and graphicsA graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene.Learn more are used to represent real-world objects on a map or scene. Every feature and graphic has a geometryA geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference.Learn more representing its shape and location and may have attributesAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more that further describe the object it represents. There are some fundamental differences, however, between them. The one you choose for your use case may depend on how they are persisted, how it handles different geometry types and attribute schemas, and how they are symbolized and displayed. In general, graphics are best suited for the temporary display of application-specific objects that are not persisted when the application closes.

See the Features and graphics topic for more information about when to use each of these geoelementsA geoelement refers to any geographic element in a map or map view that can be identified by its location to return attribute information.Learn more.

To learn about adding graphics to your geoviewA geoview is a base class for a map view and a scene view in ArcGIS Maps SDKs for Native Apps.Learn more, see Add graphics to a map view and Add graphics to a scene view.

3D display

To take full advantage of the 3D environment, featuresA feature is a single record, also known as a row, that represents a real-world entity. It typically contains a geometry (point, multipoint, polyline, or polygon) and attributes but it can also contain just attributes.Learn more and graphicsA graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene.Learn more provide additional API for controlling geoelementA geoelement refers to any geographic element in a map or map view that can be identified by its location to return attribute information.Learn more display in a sceneA scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data.Learn more or scene viewA scene view is a user interface that displays scene layers and graphics in 3D. It uses a camera to control the visible area of the scene and supports user interactions such as pan, zoom, tilt, and rotate.Learn more. A set of symbols has been designed exclusively for three-dimensional display.

The Render features and graphics in 3D topic describes considerations that are specific to displaying data in 3D.

Symbols

Your app can load mapsA map is a collection of layers that are displayed in 2D. It is typically composed of a basemap layer and data layers.Learn more and scenesA scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data.Learn more created with ArcGIS ProArcGIS Pro is a professional desktop GIS application that can explore, visualize, analyze, and manage 2D and 3D data.Learn more or the ArcGIS OnlineArcGIS Online is a GIS mapping, analytics, data hosting, and content management software as a service (SaaS) product. It includes applications, tools, APIs, and location services for users and developers. It is subscription-based and requires an ArcGIS Online account.Learn more Map or Scene Viewers. These tools allow you to style your map or scene as you want it to appear in your app without having to write code. The advanced symbols used by ArcGIS Pro and the ArcGIS Online Map Viewer, also known as Cartographic Information Model (CIM) symbolsA Cartographic Information Model (CIM) symbol is an advanced, multi-layer symbol produced by ArcGIS Pro, client APIs, or developer code.Learn more, are supported by this API.

You can also create your own symbols and control the display of features and graphics in your app. See the Symbols, renderers, and styles topic for information about symbolizing data.

Renderers

A rendererA renderer is a collection of rules and symbols used to display the data in a layer.Learn more is a collection of one or more symbols. When applied to a layer or graphics overlayA graphics overlay is a client-side, temporary container of graphics to display on a map view or scene view.Learn more, a renderer displays geoelementsA geoelement refers to any geographic element in a map or map view that can be identified by its location to return attribute information.Learn more using the appropriate symbol. If it contains more than a single symbol, a rendererA renderer is a collection of rules and symbols used to display the data in a layer.Learn more uses logic to determine the symbolA symbol defines the properties used to display a geometry or text.Learn more to apply to each geoelement, based on one or several attributeAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more values. A set of raster renderers is provided to display rasterA raster is a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters include digital aerial photographs, imagery from satellites, digital pictures, and scanned maps.Learn more data according to their cell values.

When symbolizing geoelementsA geoelement refers to any geographic element in a map or map view that can be identified by its location to return attribute information.Learn more in your map, you may need to convey several pieces of information, from different attributes, with a single symbol. You can try to symbolize such data using a unique value rendererA unique value renderer is a renderer that defines a distinct symbol for each unique data value returned from a field or expression in a layer.Learn more, but as the number of fields and values increases, that approach becomes impractical. With a dictionary rendererA dictionary renderer is a renderer that uses a style file generated in ArcGIS Pro from a rule engine and is used to display types of advanced symbology on a map, such as military symbology.Learn more, however, you can build each symbol on the fly based on one or several attributeAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more values and also handle a nearly infinite number of unique combinations.

See the Symbols, renderers, and styles topic for an overview of the available renderers. Display symbols with a dictionary renderer describes how to create and apply a dictionary renderer to a layer.

Labels

Feature layersA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more, graphics overlaysA graphics overlay is a client-side, temporary container of graphics to display on a map view or scene view.Learn more, and map image layerA map image layer is a data layer that can access and display map images that are created dynamically as users zoom or pan around a map view.Learn more sublayers in your app can be labeled using a combination of attributeAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more values, text strings, and values calculated with an expression. You can determine how labels are positioned and prioritized, and how conflicts between overlapping labels are automatically and dynamically resolved.
