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 map layers defined in a dataset?
Many datasets, such as roads and street datasets, have subsets of features (classes), and you might want to define map layers for each class of roads independent of the other features. In another case, you might have large enterprise databases with datasets that contain millions of features across wide extents—say for a whole nation or state.
How to create feature layer from tabular data?
With event data, the workaround is to create a feature class from the tabular data source instead of an event layer. If you are adding a table with no ObjectID field containing x,y data, don’t use the File > Add Data > Add XY Data command in ArcMap to create an event layer based on the table.
Can a definition query be used on a feature layer?
Even with multiple definition queries defined for a layer, all can be inactive so that no definition query is applied. This topic outlines definition queries on a feature layer, but definition queries can be used in the same way on stand-alone tables. To create a definition query on a layer, follow these steps:
Which is the default mode for graphicslayer?
Features with 2D symbols are draped on the Ground or IntegratedMeshLayer. This is the default mode for layers without z-values containing Polyline, Polygon features or Point features rendered with ObjectSymbol3DLayer. Features are placed at an absolute elevation (z-value) above sea level.
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.
What’s the difference between a top layer and a background layer?
When blending layers, a top layer is a layer that has a blend mode applied. All layers underneath the top layer are background layers . The default blending mode is normal where the top layer is simply displayed over the background layer.
What do you mean by feature layer in ArcGIS?
A feature collection is a type of feature layer. Any feature collection you add can be saved as part of the map. Doing so saves the feature collection data as part of the map. Any changes you make to the feature collection—for example, by editing data—are only reflected in the map.
Can you edit a hosted layer in map viewer classic?
If the layer is not public, anonymous users cannot access it. You can open any hosted feature layer you own in Map Viewer Classic with editing enabled. You can do this regardless of whether the feature layer is editable by other people. This allows you to use a single feature layer for both public display and internal edits.
What are the features of a route layer?
Route layers are a type of feature collection that contain four sublayers—stops, direction events, directions, and route info—each with its own properties, such as pop-ups and labels, that you can configure as desired. From Map Viewer Classic, you can save the route layer as an item in My Content and use it in other maps.
