Temporal

Temporal resolution is the frequency of data collection over the area of interest. Satellites collect data over the same area in ranges of every 16 days to new constellations that collect up to every day (https://www.planet.com/ ) (and soon intraday collections will be possible).  Aside from data subscription services (https://www.eagleview.com/product/pictometry-imagery/ )( https://go.nearmap.com/ )( https://www.terravion.com/ ), manned and unmanned aircraft can collect data as-need.

This resolution can also refer to the critical timing of data collection. You must plan around most satellite collections; however, some satellites can be commanded to capture data over a certain area at a certain time. Again, manned and unmanned aircraft see an advantage here because they can be used as-need.

If you plan to do a temporal analysis over the same area, you need to implement some means of spatial control. This most often means you use easy to identify landmarks to “tie” the different collections together. More likely with unmanned aircraft remote sensing, you may need to implement your own control. See Spatial Scale & Control. 

Lastly, if you are using manned or unmanned aircraft to collect data for temporal analysis, it is wise to use the same mission profile for each data collection. Using different flight lines may introduce error when conducting a temporal analysis.
