Sensor: All sensors will be searched if nothing is selected in
this list. To restrict the search to specific
sensors, click on either ETM+, TM, or MSS. To remove or add another
selection, shift (or Apple) click.

WRS Type:
For ETM+ and TM, this should always be set to WRS-2. When searching
MSS, this should be set to WRS-1 (but some of our MSS holdings are
in WRS-2). Searches in the "Path/Row Search" based on the metadata
and not on the spatial coordinates. If you wish to search by path/row
spatially, use Map Search instead.
See the USGS page for more information about the
Worldwide Reference System.

Acquisition Date:
To search by the acquisition date
of the data, enter in the starting and ending dates you want to search.
If you want to search for a specific day, set the starting and ending

in the starting date. To search from a date to the earliest date
available, only enter in the ending date. Dates can be in either of
the following formats:
where (mm) is the month number, (dd) is the
day of the month and (yyyy) is the year. Years can have either
two or four numbers.

New Since: Use this to search for data that has been recently
added. The search is done by querying data that has been added since a
certain number of days, weeks, or months ago from the present date. Type in a
number and select the units (days/weeks/months).

by certain attributes, click on attributes found in either the
