Data organization

The data are organized in a gridded data structure, i.e. data cubes. The tiles manifest as directories in the file system, and the images are stored within.

Check out this tutorial, which explains what a datacube is, how it is parameterized, how you can find a POI, how to visualize the tiling grid, and how to conveniently display cubed data.

Data Cube definition

The spatial data cube definition is appended to each data cube, i.e. to each directory containing tiled datasets, see Data Cube definition.

Product type

  • Time Series Time Series products have as many bands as there are available or requested time steps. If no temporal subset was specified: the TSS product contains one band per available acquisition (this may vary between the tiles), the RMS product contains one band per available acquisition (this may vary between the tiles), the TSI product contains one band per interpolation step, the FBY product contains one band per year (do not overdo YEAR_MIN/MAX, this will give many useless bands), the FBM product contains one band per month (up to 12, depends on MONTH_MIN/MAX and DOY_MIN/MAX), the FBW contains one band per week (up to 52, depends on MONTH_MIN/MAX and DOY_MIN/MAX), the FBD product contains one band per DOY (up to 365, depends on MONTH_MIN/MAX and DOY_MIN/MAX), the 26 LSP products contain one band per year (do not overdo YEAR_MIN/MAX, this will give many useless bands).

Change and Trend

The Change, Aftereffect, Trend (CAT) product (following [Hird et al. 2016](https://ieeexplore.ieee.org/document/7094220) contains extended change and trend parameters. CAT detects one change per time series, splits the time series into three parts, and derives trend parameters for the three parts:
