• When a building's outline is already identifiable on satellite data, which is often the case for pre-existing buildings, users have the option to trace the building's corners without needing to visit the site physically. However, it is generally advised to conduct a site visit for data collection purposes.

• When the Building Data option is selected, the user's location is automatically displayed on the map, and they can also use the "Locate Myself" button to pin-point their exact location.

• The users may need to manually adjust the map by dragging it to align with the specific location they wish to collect building data from.

• When there is no building footprint on the satellite data (usually a case when the building has been constructed recently), the user must physically visit the site and trace corner points of buildings.

• In this case, the user needs to go to each corner of the building and start collecting corners of the building by tapping on the map.
