Envelope
The minimum bounding rectangle that encloses a spatial feature or dataset, used for spatial queries and extent definition (standard GIS usage).
What is the definition of an Envelope?
In GIS and spatial analysis, the smallest rectangular boundary—also known as a bounding box—that fully encloses a spatial feature or collection of features is referred to as an envelope. It is defined by the minimum and maximum coordinates (typically X and Y) that include all the points of the feature.
Envelopes are used to increase computing efficiency, streamline geographical searches, and rapidly characterize the spatial scope of data. For instance, in order to determine whether a more thorough comparison is required, a system may first determine whether the envelopes of two features overlap before conducting a thorough geographical analysis. In essence, an envelope offers a straightforward method of depicting the space that is filled by geographical features.
