A tool that creates zones from satellite images.

SERVICE DESCRIPTION

There is a reference layer with LPIS fields loaded into the application initially (one WMS layer for smaller scale to get oriented, and another one WFS layer, that is loaded at a bigger scale for actual field selection). The user selects his field/s from the map and then has the opportunity to select product type (EVI/RVI4S1). This sends the request get_dates to the server and the server responds with available index dates. The available dates are then displayed as a list. User then picks up the date he is interested in from the list and fills in other inputs (number of quantiles, gaussian smooth size to apply). After that the request is sent to the server, processed and the resulting management zones are sent back in geojson format. Newly there is an option to select an algorithm that will compute the management zones but it is not yet implemented in the app. There are two algorithms available. Initial one proceeds like:Select imagery for the selected date for the given locationCrop imagery by the field borders (plus necessary buffer to account for gaussian filter in the next step)Apply Gaussian filter to smooth image with sigma parameterDivide values of pixels into x quantilesVectorize zones into requested format and send to user
