From the Search tab, use the Geospatial field to narrow your search to a specific geospatial area. If you do not make a geospatial selection, the default is to search the whole globe. If you limit your search to a specific area, the search will return all available data that intersect with your selected area.
To modify the geospatial fields, use the Choose View option buttons North Polar, Global, or South Polar to change the view of the map. The North and South polar view maps work well for searches that cross or are near the poles. The global view map works well for searches that cross the equator.
After selecting a map view, modify the geospatial fields to specify your area of interest, or use your mouse directly on the map to draw a bounding box by clicking and dragging.
The North Polar and South Polar map views use corner points in lat/lon pairs to define the area of a box. You only need to define the upper left and bottom right corners in lat/lon pairs (the white text boxes) to create your area. The other two corners (the grey text boxes that do not allow you to enter text) are created automatically based on the box drawn.
The Global map view uses lat/lon bounds (northernmost, southernmost, westernmost, and easternmost) to define the area of a box. If you use the mouse to draw the area on the map, the fields are filled in automatically, based on the box drawn.
To reset the map, click on the Reset Map & Selection button.
