What is simple feature specification?
A simple feature is defined by the OpenGIS Abstract specification to have both spatial and non-spatial attributes. Spatial attributes are geometry valued, and simple features are based on 2D geometry with linear interpolation between vertices.
What is Open geospatial consortium simple Features specification about?
Simple Features (officially Simple Feature Access) is a set of standards that specify a common storage and access model of geographic feature made of mostly two-dimensional geometries (point, line, polygon, multi-point, multi-line, etc.) used by geographic information systems.

SQL, as de ned in [ISO99], is extended to man- age data like texts, still images, spatial data, or to perform data mining. The standard is grouped into several parts.
What is SF in R?
Package sf represents simple features as native R objects. Simple features are implemented as R native data, using simple data structures (S3 classes, lists, matrix, vector). Typical use involves reading, manipulating and writing of sets of features, with attributes and geometries.

How are feature flags implemented in.net core?
The .NET Core Feature Management libraries provide idiomatic support for implementing feature flags in a .NET or ASP.NET Core application. These libraries allow you to declaratively add feature flags to your code so that you don’t have to write all the if statements for them manually.
