Data cube technology
Satellites have been generating large amounts of images of the Earth for several decades. These images are an important source of information about changes on the Earth’s surface. Data cubes are a way of organizing these series of images from the sky or from space for various dates, i.e. time series of satellite images, in order to simplify their use.
Earth observation data cubes help to:
- Reduce the preparation time needed for the use of numerous satellite images which represent a large amount of information to be processed.
- Simplify analysis and provide quick answers to questions related to the environment, floods, urbanization, and others.
- Facilitate access to data over the internet by improving the response time for displaying images in the web browser and allowing interaction with them.
Big data
Natural Resources Canada's data scientists are leveraging new Big Data technologies to make sure Earth observation data are available and accessible.
Cloud computing
The data cube is deployed in a cloud environment that facilitates implementation and ensures good performance of the tools. This type of environment makes it possible to adjust cloud-based resources in real time according to the number of people accessing the images.
Standards and interoperability
The data cube resources are accessible through standardized web services approved by the Open Geospatial Consortium, an international standards organization for geomatics.
