2. Point to New > Feature Class.
3. Type a name for the feature class.
4. Choose from the drop-down list the type of features that will be stored in this feature class.

How do you create a line feature class?

To create a line feature class, right-click the database, click New, and click Feature Class. Drag the feature class onto the map. A feature template with default settings is automatically generated for the new layer.

What is a feature class ESRI?

Feature classes are homogeneous collections of common features, each having the same spatial representation, such as points, lines, or polygons, and a common set of attribute columns, for example, a line feature class for representing road centerlines.

What is the difference between a layer and a feature class?

Feature Layer: A layer that references a set of feature data. Feature data represents geographic entities as points, lines, and polygons. Feature Class:In ArcGIS, a collection of geographic features with the same geometry type (such as point, line, or polygon), the same attributes, and the same spatial reference.

How do I create a feature class in Arcgis pro?

What are the four types of feature classes?

The four most commonly used feature classes are points, lines, polygons, and annotation.

What’s the difference between a shapefile and a feature class?

Feature classes are homogeneous collections of common features, each having the same spatial representation, such as points, lines, or polygons, and a common set of attribute columns, for example, a line feature class for representing road centerlines.

How do I train a classifier for supervised image classification?

In supervised image classification, you need to train the classifier to assign pixels or objects to a given class using training samples. The class categories are determined by your classification schema, and the training samples can be generated using the Training Samples Manager pane.

What are the features of a feature class?

Feature geometry and feature coordinates Feature classes contain both the geometric shape of each feature as well as descriptive attributes. Each feature geometry is primarily defined by its feature type (point, line, or polygon). But additional geometric properties can also be defined.
