README
The SenseCarbon Time Series Viewer can be used to visualize time series of remote sensing data. Its major aims are:
(i) to support a Quantum GIS (QGIS) based labeling of time series data,
(ii) to use the remote sensing imagery "as is"
(iii) to avoid a complicated installation process
The viewer works with the python packages that are part of the most recent Quantum GIS (QGIS) installation.
Features
- Uses the Geospatial Data Abstraction Library (GDAL), which supports up to 142 raster image formats
- Recognizes the temporal order of input images implicitly. Date-time information is extracted automatically: by evaluating each images meta data, the image filename or the entire file path to find a date-time stamp.
- Supports different spatial projections: There is no need to warp the image data into one projection.
- Supports different sensors: images similar in its spectral and spatial configuration are assumed to be taken by the same "sensor".
- Visualizes multiple band combinations, separated by sensor
- Spatial extends of image chips can be specified in QGIS by selection of single coodinate or rectangle
- Color scaling is applied to the entire time series, e.g. to visualize and compare surface reflectance data
Missing Features / ToDo's
Several. It try to keep an updates list in the issue section. Some of them:
- on-the-fly calculation of (simple) spectral indices
- colorbar/gradient visualization of single bands
- support of mask information
- temporal & spectral profiles
- drag 'n drop interactivity
- python2 and python 3 interoperability
