Step (4). Pick Target Sites
Search for interesting targets under the daylight portion of the orbit track. The slider map provides only a rough estimate of where the shuttle will be passing over. You will need to cross-reference these targets with a more detailed map or atlas in order to pick more specific targets. For example, the descending node for orbit 18 is 38.19° E. If you line up the ground track for this orbit, it looks like the shuttle may pass over Spain and Madagascar. You will then need to accurately check whether these selections lie within the camera footprint using the SMOC Map web page (see step 6 below). 

The SMOC Status web page will also list current weather and geological occurrence information in the Environmental Highlights box. Additional weather and geological occurrence information should be obtained using world wide web weather sites (see page 2.17 of Chapter 2 for more information). 

Step (5). Keep a Record of Your Target Selections
You'll need to keep track of your selections, and of important information associated with them as you go through the steps of selecting your targets. Write down the target name, orbit number, the latitude, longitude, MET, reason for selection and priority on your "list of targets." Refer to page 7.33 to see an example of how to keep track of your selections. 

Step (6). Confirm Targets
Use the SMOC Map web page to confirm the site is under the orbital track, within the camera footprint, and in daylight (see page 7.10-7.13 on "How to Use the Map Page"). The SMOC Map web page will tell you exactly how many miles off the ground track your selection is. 

Step (7). Determine MET of the Photograph
Use the SMOC Map web page to find the MET of the site, and record it on your list of targets (see pages 7.10-7.13 on "How to Use the Map Page"). The SMOC Map web page will give you a precise MET of when the shuttle will pass over your target.
