To search the Landsat 7 data archive, highlight 'LANDSAT-7 LEVEL-0R WRS-SCENE V002' for reformatted Level 0 data, or highlight 'LANDSAT-7 LEVEL-1 WRS-SCENE V002' for Level 1 data.   ^Tip!!

It is recommended that you confine your search to a specific geographic region and/or a specific time range. This will help to minimize the response time and will return granules that most closely cover your area of interest. These options are found under 'Optional Search Criteria' . Please see Figure03 .

To specify a geographic region, click the 'Edit' button under 'Geographic Region' . Please see Figure03 . That will take you to a screen that shows a pull down menu with 'I want to do a GLOBAL SEARCH' already selected. Click-and-hold that menu to see your options. Highlight the method you wish to use and click the 'OK' button. If you know the latitude and longitude, or the WRS path and row of your desired area, highlight that option and click the 'OK' button.

If you selected either the 'Type in Lat/Lon Range' or 'Type in Path/Row' option, you will be taken to another screen where you can type in your latitude and longitude or path and row. Enter the range and click the 'OK' button. ^Tip!!

If you selected one of the map options, you will be taken to a screen that displays a map of the world. If you selected 'Orthographic Map (Java)' , you will need to click and drag your mouse over a region on the map. Click the 'OK' button. If you selected 'Equatorial Map' , 'Stereographic N-pole Map' or 'Stereographic S-pole Map' , to select your region, click on the map once for the upper left coordinate, then click the map again for the lower right coordinate. Click the 'OK' button. ^Tip!!  The coordinates and defined area will look similar to Figure 04 .
