Date/Type Tab: At the top of the map, click on
the Date/Type Tab to get the query parameters to refine a search
by dates and type attributes. These parameters will appear below the map.
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
dates to the same value. To search from a date to the present, only enter
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:
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.
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).
Type Attributes: To require or exclude data
by certain attributes, click on attributes found in either the
"Require" or "Exclude" lists. To remove or add additional attributes
to the search, shift (or Apple) click items. The definitions
for Level 1G, Orthorectified, Terrain Corrected, and Not-Validated
are described under Data Attributes and
the definitions for BSQ, GeoTIFF, and MrSID are described under
Update Map: Once the parameters have been entered,
click on this button to update. The map will change the coverage to
show data that match your parameters.
