The systems and methods described herein provide improvements to mapping project sites by using ground and/or aerial imagery. A system can receive one or more ground images of site locations within a site area and metadata associated with each of the one or more ground images. The metadata can include GPS coordinates that correspond to the one or more ground images. The system can determine that aerial imagery represents at least the one or more site locations and determine a relative position of each of the one or more site locations within the aerial imagery. Such a determination may be based on the metadata (e.g., on the GPS coordinates). The system can then generate data to display on a user interface one or more features, such as a map, an indication of the site area, and one or more indicators.
