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

Installation

The following instructions use git commands. If git is not available in your shell, you can download it from https://git-scm.com/downloads.

Windows

1. Open your command line and clone this repository to your local QGIS Python Plugin Folder

    cd %USERPROFILE%\.qgis2\python\plugins 
    git clone https://jakimowb@bitbucket.org/jakimowb/sensecarbontsviewer.git

2. Start QGIS, go to Plugins -> Manage and Install and enable the "SenseCarbon TSV" Plugin

3. Download updates if available

    cd %USERPROFILE%\.qgis2\python\plugins\sensecarbontsviewer
    git pull
