Overview

The Overview module is the users' information gate to compiled and visualized agri-data fetched from all different modules of the system. Users can get an instant overview of operations, production flows, crop status and many more real-time or processed data.

Overview is connected to all modules, mainly for receiving information to be presented to the user for an at-a-glance overview of the specific field. For example from Satellite retrieves all recent data regarding vegetation indexes in order to present the corresponding (NDVI, EVI, SAVI) treed and mean values.

Overview Implementation

The presented data refer to the selected cultivation period. The selection of another period provides the corresponding period data

1. Basic information related to the selected field

	Select "Season" to view the relevant field information "Menu" button for "Edit Field" actions

1. Current soil condition of the selected field

2. 5-days weather forecast for the selected field

3. Current weather conditions for the selected field

4. Growing Degree Days (GDD) area graph that presents the accumulated growing degree (in °C) for each day of the cultivation season, calculated by (Tmax+Tmin)/2−Tbase)(Tmax+Tmin)/2−Tbase), where TmaxTmax and TminTmin refer to the maximum and the minimum temperatures, respectively, while TbaseTbase refers to a defined temperature below which the development of the plant stops. For instance, for a day with a maximum temperature of 20°C20°C and a minimum of 12°C12°C, and Tbase=10°CTbase=10°C​, the accumulated growing degree is calculated to 6°C6°C​. This measure of heat accumulation is very useful to predict, among others, the date that a crop will reach maturity. In order for the system to produce the GDD area graph, it is pre-required for users to have inserted a seeding and a harvesting log task in the Calendar module of the system.

5. NDVI and Accumulated Precipitation area graphs. Specifically, the green graph describes the trend of the average NDVI values for the selected field, taking into consideration the tolerant cloud coverage percentage for every observation date. In respect to the blue graph, this represents the accumulated precipitation (in mm) in the selected field, for the selected cultivation season.

As far as the NDVI and Accumulated Precipitation area graphs are concerned, it should be highlighted that the start date is defined as the seeding date for the selected field, while the end date is defined as the harvesting date, also for the selected field. Both dates are created from the Calendar module. By default, in case none seeding event has been saved in the Calendar module, the system produces a graph with a start date three months before the current date. Similarly, in case none harvesting event has been saved in the Calendar module, the system produces a graph with an end date of the most recent observation date.
