Planning

Primary Objectives

Your challenge is to develop an easy-to-use, web-based application that supports the comparison of ground-based observations with Landsat data by allowing users to define a target location, receive notifications when Landsat is to pass over that location, and then access and display the corresponding Landsat SR data.

Think about how your tool can:

• [x] Allow users to define the target location. Will they specify the place name, latitude and longitude, or select a location on a map?
• [x] Determine when a Landsat satellite is passing over the defined target location.
• [ ] Enable users to select the appropriate lead time for notifications about the overpass time and the method of notification.
• [ ] Display a 3x3 grid including a total of 9 Landsat pixels centered on the user-defined location (target pixel).
• [x] Determine which Landsat scene contains the target pixel using the Worldwide Reference System-2 (WRS-2) and display the Landsat scene extent on a map.
• [ ] Allow users to set a threshold for cloud coverage (e.g., only return data with less than 15% land cloud cover).
