Worldview

Worldview is a software tool designed for interactively browsing and downloading imagery from NASA's Earth observing satellites.


Worldview Goals

Worldview is a software tool designed for interactively browsing and downloading imagery from NASA's Earth observing satellites. Building upon a set of open source mapping and user interface libraries, it provides an environment to visually discover interesting phenomena as observed by NASA satellites, then download the data for further analysis. It was originally designed to address the needs of the near real time applications community to provide relevant information for time-critical scenarios such as wildfire and flood management. As such, satellite imagery is available to be viewed in Worldview within four hours of observation, the imagery can be viewed in its highest, or native, resolution, and the imagery can be panned and zoomed rapidly through space and time to find the most relevant/cloud-free/etc information available.

Project Goals

To enable exploration of full-resolution daily, multi-day, and swath-based Earth imagery. Once “interesting” imagery is found, Worldview provides a mechanism to download the underlying data, enabling the scientist to perform further analysis on it.

Functional Goals

  1. Provide an interactive (zoom-able, pan-able) map interface.
  2. Provide an interactively adjustable time widget.
  3. Allow downloading of the onscreen imagery.
  4. Allow downloading of the underlying data which created the imagery.
  5. Enable saving and sharing of results.

Evolvability Goals

  1. Scale the interface to handle an increasing number of imagery products available.
  2. Provide metadata about each imagery product available.
  3. Provide examples showing how imagery products can be used.

Usability Goals

To build an interface which reduces the traditional barriers to using NASA satellite data (e.g., large files, specialized file formats, disjoint imagery broken into “granules”, etc).
