1. A method for detecting a change in a field of view from a first point in time to a second point in time, the method comprising: generating a current three-dimensional dataset of the field of view from a point of reference based on data received in real-time; determining a location of the point of reference based on geo-spatial data; accessing a stored three-dimensional dataset of the field of view, wherein the stored three-dimensional dataset is generated from data previously captured at the point of reference; and providing one or more alerts signifying the change in the field of view between the current three-dimensional dataset and the stored three-dimensional dataset.
