📈Creating raster time series

Overview

Raster data in Ellipsis Drive can be organised as time-aware datasets by assigning data to timestamps.

This enables temporal navigation of raster layers using the time slider in the viewer.

---

Time series structure

To represent raster data over time, you can create one or more timestamps within a raster layer.

Each timestamp can represent:

• A single acquisition date

• Or a defined time range

Raster files are assigned to the appropriate timestamp based on when the data was captured or generated.

---

Processing behaviour

After upload, raster data is processed and indexed before becoming available in the viewer.

Once processing is complete, the dataset can be explored using spatial and temporal navigation tools.

---

Viewing time series data

Time series raster layers can be explored using the time slider in the Viewer.

This allows you to:

• navigate between timestamps

• Compare changes over time

• Visualise temporal patterns in raster data

Key rule

All raster files that belong to the same timestamp must be assigned to that timestamp during upload.

This ensures correct temporal grouping and consistent visualisation in the viewer.
