Introduction
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 is a tool for analyzing "cubes" of multi-temporal imagery. jCube's "cubes" have at least 3-dimensions: x,y, and time. Multispectral image data is also used if available. In that case the cubes can be 4-dimensional: x, y, color, and time.

Multi-temporal imagery is a time series of images of a specific area of interest. The number of images varies. It may be from a few to hundreds. The time spanned may be seconds to years, depending on the application.

Multi-temporal analysis can increase the value and information derived from imagery. As examples: enhance image spatial resolution and dynamic range; track animal migrations; map urban growth; monitor geological changes; map changing water levels and shorelines (as in the example below).

jCube is accessed by logging on a remote server over an Internet connection. Access is free. Additional consultations and specialized support is available to interested users..

Please use the links on the left for more information. 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.
