What is a Featurelayer?
A feature layer is a grouping of similar geographic features, for example, buildings, parcels, cities, roads, and earthquake epicenters. Features can be points, lines, or polygons (areas). Feature layers are most appropriate for visualizing data on top of your basemaps.
What is a graphic layer?
Graphics layers are containers for graphic elements—geometric shapes, lines, points, text, or pictures. They provide a way to include simple notations on a map or layout that highlight particular areas or label places. You can use graphics layers to visualize a map without creating features.
What is a feature class ArcGIS?
A feature class is a collection of features with the same type of geometry: point, line, polygon, or annotation. A feature class can be stored with other feature classes in a feature dataset in a geodatabase or as a stand-alone feature class in a geodatabase. A feature class can also be stored in a shapefile.
What is a layer ArcGIS Pro?
In ArcGIS, layers are collections of geographic data. Layers reference a data source, and if ArcGIS Pro interprets data as spatial, the data’s properties and attributes specify how the layer draws on a map, scene, or layout. The layers are displayed in a particular order, which is shown in the map’s Contents pane.
What is map image layer?
A map image layer is a type of web layer that can include both feature and non-feature layers as sublayers. All sublayers in a map image layer can be visualized; feature sublayers can be queried. Map image layers can be configured to draw dynamically from data or from new or existing cached tiles.
What are layers in GIS?
Layers are the contents of a map. They include a wide range of information about people, the earth, life, and so on, and are composed of imagery, tiles, features, and more. Your company is introducing online GIS into its suite of tools that beginning employees must know to compete in today’s workplace.
What can you do with feature layers in ArcGIS?
You can set properties for feature layers—such as style, transparency, visible range, refresh interval, and labels —that control how the layer appears in the map. Using a feature layer, you can view, edit, analyze, and execute queries against features and their attributes.
Which is better, a featurelayer or a graphicslayer?
It is generally preferred to construct a FeatureLayer with its source property when working with client-side graphics since the FeatureLayer has more capabilities than the GraphicsLayer, including rendering, querying, and labeling. Graphics can be added to an instance of GraphicsLayer in several ways.
How are feature layers similar to hosted feature layers?
These layers are similar to hosted feature layers with the following differences: The data is not copied to ArcGIS Online; it stays in the data source you registered with the ArcGIS Server site. When you delete the ArcGIS Server feature layer, the data is not deleted.
How are scene layers published in ArcGIS Online?
Publish scene layers from feature layers containing points or multipatch layers. Hosted feature layers can be published through a variety of workflows, including ready-to-use templates. If you host layers on your own ArcGIS Server site, you can still use these ArcGIS Server feature services as layers in ArcGIS Online.
