How to calculate distance and area in ArcGIS?
The Calculate Geometry command, which is accessed from the table window, will calculate lengths, areas, x,y coordinates, and so on, and place the values into a field in the attribute table. To learn more about Calculate Geometry, see Calculating area, length, and other geometric properties.
How to return the oriented minimum bounding box in QGIS?
Returns an offset line at a given distance and side from an input line. Returns the oriented minimum bounding box for the geometry, which is the smallest (by area) rotated rectangle which fully encompasses the geometry.
Which is the generic container for geometry in QGIS?
A geometry is the spatial representation of a feature. Since QGIS 2.10, QgsGeometry acts as a generic container for geometry objects. QgsGeometry is implicitly shared, so making copies of geometries is inexpensive. The geometry container class can also be stored inside a QVariant object.
