Methods, systems and devices for supporting delta coding for remote sensing are described. For example, a system that supports remote sensing of information may include processing capabilities configured to determine a difference between sensed information and a baseline condition, such as a base map of information. The determined difference from the baseline condition may be communicated via a communications link (eg, a wireless communications link, a satellite communications link), which may be referred to as or otherwise associated with "delta coding" of information sensed by the remote sensor system. can In some examples, delta coding may support a smaller transfer of information over a communication link than communicating all of the sensed information. By communicating such differential information, the remote sensor system may thus assist in updating information more efficiently, more frequently, more quickly, or more reliably, among other advantages.
