Mode and Statistics

AutoMap offers three different modes of operation that build on top of each other:

  1. Download - Mode

    2. All scenes that fit the input criteria are identified, their respective image bands are downloaded, scaled to the same spatial resolution and merged to single multiband tifs that also contain a cloud mask, NDVI and NDWI.

  2. Composite - Mode

    3. Based on the multiband tifs generated in previous mode, the data for selected area of interest is aggregated over the temporal domain based on statistics the user can define (e.g. median and standard deviation over a year).

  3. Classification - Mode

    4. For each selected satellite composite, a classification is carried out, using a user defined training dataset.

Useful Tip:

Please refer to the Process Overview in the Introduction for detailed information on the general workflow!

Satellites

Select the satellites that should be considered using an integer of arbitrary order (2578 = 8572). Double selections (e.g. selecting Landsat 7 and also All) will be resolved accordingly.

Useful Tip:

Please refer to the Satellites in the Introduction for detailed information on the available satellites!

Dates

Start and end dates can be selected manually by writing dates in format dd.mm.yyyy or by picking with the provided widget. The dates and their resulting interval must fulfill the following criteria:

  1. The end date must be after the start date.
  2. The end date must not be in the future.
  3. The end date must not be before 01/01/1984.

Boundary File

The boundary file defines the area of interest and is a vector geojson-file stored with your account in the File Management Tool.

Important Note:

The boundary file must be a GeoJSON vector file! The unary union of all contained shapes is considered the boundary.

Training Data

Classifications need user-provided training data stored with your account in the File Management Tool that is defined as CSV file containing integer class values per year and X/Y coordinates in the EPSG:4326 reference system (WGS:84). The columns are named per year ("yyyy"), "X" (lon) and "Y" (lat). The year closest to the selected time range will be considered. Only columns containing just digits are considered year-class columns.

X Y 2018 2017 2016
8.22 46.34 14 14 14
7.54 46.95 15 15 14
7.93 48.21 10 9 18

Note:

Using the freely available QGIS Application, it is easy to convert other data formats to csvs with according geometry fields.
To convert points stored in another file type refer to link but select GEOMETRY: AS_XY.
To convert polygons refer to link. Note that there are many ways of exracting points from areas and that users should pick a strategy suitable for their needs.
