The crucial factor in determining the accuracy of GPS data collection is the capabilities of the GPS receiver and satellite alignment. The performance of the GPS receiver plays a significant role, as it influences the system's ability to acquire signals, process data, and determine precise locations. High-quality receivers can better mitigate errors and enhance signal processing, leading to more accurate positioning.

Additionally, satellite alignment is essential because GPS relies on a constellation of satellites broadcasting signals. A clear view of multiple satellites is necessary for accurate triangulation of position. If the satellites are poorly aligned or if the receiver has limited visibility to the satellites (due to obstacles like buildings or trees), the accuracy of the collected GPS data can be negatively impacted. Therefore, both the capabilities of the GPS device and the geometry of satellite positioning directly affect the precision of the data collected.

While the type of map, distance to features, and mode of transportation may influence the interpretation or application of the GPS data, they do not directly affect the fundamental accuracy of the data itself in the same way that receiver capabilities and satellite alignment do.
