Quick start & practice
Using Remote Desktop
Navigating the jCube window

There are three ways to use jCube

  • Try jCube on sample LANDSAT image data
  • Downloading more image data directly from the USGS image archive to jCube. (Available soon)
  • Uploading data sets from your computer to the jCube server. (Available soon)

The current version of jCube is a limited capabilities "Beta-testing" release. It runs only one application with LANDSAT images.

Why LANDSAT imagery in particular?
Beta release limitations.

Coming soon: more applications and capabilities


Introduction ...

jCube processes "cubes" of multi-temporal imagery. The image cuves have at least 3-dimensions: x,y, and time, and often are 4-dimensional (x, y, color, and time).

Multi-temporal imagery is a time series of images of a specific area of interest or subject. The idea in any multi-temporal processing is to somehow combine the many images into something new an more useful than the individual images. Some examples are:

  • enhance spatial resolution and dynamic range
  • track animal migrations
  • monitor geological changes, such as shorelines (example below)
Left: Single image of upper Gulf of California. Right: multiple images processed into a inter tidal zone map.

The number of images varies from a few to hundreds. The time between consecutive images may be seconds to years, depending on the application.

jCube is accessed by logging on a remote server over an Internet connection. The links on the left lead to more information and instructions for using jCube. The Quick start link takes you through a sample data set from start to finish. After this exercise you can repeat with other data sets, or use jCube on your own data.
