🗺️ Paths and layers
Any item in Ellipsis Drive is referred to as a path. A path can be a folder, a file, a bookmark or a layer. Folders and files are similar to what you are used to in a regular file system. Layers within Ellipsis Drive are the holders of spatial data. These layers can be of type raster, vector and point cloud.
Raster Layer
A layer created for storing raster data is called a raster layer
Vector Layer
A layer created for storing vector data is called a vector layer
Point cloud
A layer created for storing point cloud data is called a point cloud layer
A bookmark is a reference to the Ellipsis Drive viewer in which one or more layers can be loaded according to a certain style and with a certain view port. Bookmarks are presentation built from the "legos" that are layers.
Vector Layer

Feature
A feature is a representation of a real-world object on a map. These features have a geometry that can be a point, multi point, line, multi line, polygon or multi polygon. A feature also has properties containing some non-spatial information. These features can have multiple versions. Users can attach time series and messages to features. A message can have an optional image.
Geometry
A geometry is used to represent the spatial component of features . The geometry gives some geographical location.
Style
A style defines a colour for the vector based on a set of rules applied to the properties of the vector.
Properties
A vector can have properties, these contain the non spatial information of the feature
Timestamp
A timestamp is a container for all vector files belonging to the same date range.
Time series
