AI summary

Systems, methods and non-transitory computer readable media for exploring images of construction sites by construction stages are provided. For example, a plurality of images of a construction site may be accessed, each image of the plurality of images may correspond to a location in the construction site and a construction stage. In response to a received indication of location and a received indication of a construction stage, an image corresponding to the indicated location and to the indicated construction stage may be selected and presented. In response to a received indication of location and a received indication of a capturing time, an image corresponding to the indicated location and to the indicated capturing time may be selected and presented.
