Our goal is to provide the most current and accurate maps (satellite images) as possible as they become available. We use a combination of map companies in order to give the flexibility of zooming in close to the ground, to have the most current maps on the market, and to allow maps to be view-able offline so you can use our apps and maps in very remote areas. All of these options are not possible with most other apps like ours.
Maps are updated by the mapping company as they become available. Not all areas are updated at the same time and not all companies have the same maps. Even more, due to the images changing when you zoom in and out those maps are different photos as well and could vary with cloud shadows, time of year, and even in quality. More rural areas typically get updated less than populated areas.
