USGS Global Visualization Viewer: Quick Start Guide
Getting Started
The USGS Global Visualization Viewer is a
quick and easy online search and order tool for selected satellite data. When
you first open the USGS Global Visualization Viewer, you will see the Global
View:
Getting started is as easy as clicking on the world map
near your area of interest.
If you wish to view data from a satellite sensor other than Landsat 7 ETM+,
you may select the sensor and sensor type before clicking on the
map, or you may select another sensor later.
Getting Around
Once you have clicked on the world map, you will be taken to the Browse Viewer:
This view shows a mosaic of the most recent cloud-free
satellite browse images around the point you selected. From here, you can
begin to explore the other satellite images from our archive:
-
Roam around on the earth's surface by clicking on either the arrow buttons
or the global locator map near the top left of the display. You can also
"shortcut" to a specific location by entering the desired
WRS-2 (WRS-1 for Landsat 1-3 data) "path" and "row" or latitude and
longitude.
-
Limit the range of scenes to view by setting search limits in the search
limits dialog box. The search limits dialog box is opened by selecting
the "Tools" menu from the menu bar and then clicking on "Search Limits...".
-
View the available images for the highlighted scene with the "Prev Scene"
and "Next Scene" buttons. You can also "shortcut" to a specific date by
entering the month and year. The possible dates will be dependent upon
the sensor, as well as the specific data in the USGS browse image
inventory.
-
Scenes with high cloud cover can be excluded by adjusting the maximum cloud
cover setting (via the "Max Cloud" drop-down menu).
-
To help determine where you are, select the "Map Layers" menu on the menu bar.
You will then be able to view political boundaries, roads, water,
north arrow, WRS Centers, and/or US Cities.
-
Limited "zoom in" and "zoom out" can be achieved by selecting the
"Resolution" menu on the menu bar and clicking on the resolution to be
viewed.
Creating a Scene List
When you discover a suitable scene, simply "Add" the highlighted scene
to your Scene List at the lower left of the display.
Modifying the Scene List
To delete a scene from the Scene List, select the scene within the list and
then click on "Delete".
Viewing Metadata & Browse
The metadata and/or browse image for any scene can be reviewed by selecting
the "Show Metadata" or "Show Browse" options from various right-click popup
menus.
Ordering Data
When your scene list is complete, click on the "Order" button in the scene
list dialog box or right-click on the scene list dialog box for a popup menu
and select
"Order List".
(NOTE: If you have scenes from different sensors, you will need to do this
separately for each sensor type).
