ASTER Overpass Predictor
Entry ID: LPDAAC_ASTER_ESTIMATOR

Summary
Abstract: The ASTER Overpass Predictor allows a user to estimate of the next opportunities for ASTER to image a location on Earth by entering the latitude and longitude for your location and then select Forecast Possible ASTER Collection Times. The information returned is based on output from the NASA Satellite Overpass Predictor, and includes both day and night possibilities.

You may also select Location Map, Topographic Map (for U.S. only), or Weather Forecast to obtain additional site-specific information for the point specified. Connections are established to services offered at other locations. For weather forecasts, note that wide spatial windows may be needed to obtain returns in sparsely populated places, but are likely to yield a long pick-list of choices in densely populated places. Narrow windows may provide no returns in sparsely populated places. Change the default setting of 2 degrees to expand or contract the area searched around the point specified.

NASA places a limit of 14 days on the generation of predictions to ensure a manageable server load. To produce longer predicts, run the predictor multiple times with start dates set 14 days apart. Note: predicts are less reliable as they move further from the satellite's "epoch date" (i.e., the time/date of the observations from which the data were derived).
