This tutorial covers searching

Earth Explorer using the interactive map.

Earth Explorer is available at

earthexplorer.usgs.gov

You’ll need to register and log in

to access imagery from Earth Explorer,

which is covered in another tutorial.

To begin a search with the interactive map,

make sure you are under the search

criteria tab on the left and

that coordinates tab is selected.

To make a single point search,

click anywhere on the map.

The latitude and longitude will

fill in under the coordinates.

You can define a line segment

to search by clicking a second

point on the map.

Create a rectangle by holding shift

and dragging the mouse to
make your selection.

You can modify any point by

dragging it to a new location.

Create a polygon by clicking

multiple points on the map.

To create a circle, select

circle under the options tab.

Your first click defines the center

of the search, and the second click

sets the radius.

You may also choose the “use map” button

to use the current view
as the area of interest.

You can use any of these methods

to interactively set your search area.

To refine the search, it is recommended

to set a date range, or specify the

number of records to return.

The next step is to determine which

data sets to search, which is

covered in another tutorial.
