# EO Time Series Viewer

Welcome to the EO Time Series Viewer Documentation!

## About

The Earth Observation (EO) Time Series Viewer is a QGIS Plugin to visualize raster based earth observation time series data.

Its major aims are:

- an integrated visualization and labeling of multi-sensor remote-sensing time-series data, based on QGIS
- to minimize the user-interaction (“mouse-clicks”) required to optimize different ways of data representation.
- an (almost) platform independent installation

## Features

- Raster images can be added to the time series without homogenisation of spatial extent or coordinate reference system. Time stamps are extracted automatically from (i) image meta data (“acquisition date”), (ii) the file name or (iii) the file directory path.
- Raster IO uses the Geospatial Data Abstraction Library (GDAL), which supports up to 142 different raster formats.
- Distinguished sensors by pixel size and number of bands and, if available, band wavelength information and sensor name.
- Spatial-temporal (“maps”) visualisation allows to show multiples band combinations in parallel, e.g. True Color and coloured infrared.
- Color stretches are applied to all raster images of same sensor and band combination. This helps to optimise color stretches for multiple images in a minimum of time.
- Spectral-temporal (“time profile”) visualisation shows raw or scaled, sensor specific band values.

### Missing Features / Outlook

- a lot of debugging, making small errors gone.
- 3D plotting for spectral-temporal surfaces
- export temporal profiles

### Feedback

Your feedback (wishes, comments, bugs, …) is always welcome. Add it to the issue section or send me an email benjamin.jakimow@geo.hu-berlin.de.
