To unfold the analytics simply select the added field from the list. You can apply a variety of analytical tools to your field once you have drawn/selected/uploaded it on the map.
1. Once the field is selected, the analytics window automatically unfolds at the bottom of the screen. Graphs that display a representation of NDVI (normalized difference vegetation index) are in the centre of this window. Each curve can be disabled by clicking the corresponding colored buttons in the legend. This allows you to disable the unnecessary and compare indices for those years that are of interest to you. There is also the possibility of comparison with the average values for the whole district, thus you can understand how your crop is developing in accordance with general trends. To select data source use the switcher on the right, Sentinel-2 and MODIS satellites are available for now. Sentinel-2 provides you with a greater resolution imagery but MODIS, in turn, has a higher revisit frequency. To visualize the data for the specific day, hover over the curve.
2. To select the start and end dates of the comparison for the area and weather data use the plotting tools on the left. To visualize the info for the specific dates, set them in the calendar.
3. To compare your field with another district, select it from the drop-down list.
To add weather data to the graph, select the required value from the Weather data drop-down list. You can add such parameters as temperature, precipitation, winter kill, cold stress and heat stress, among others. The Winter kill option displays low temperatures that threaten your winter crops so that you can easily track them and draw conclusions based on the NDVI index. The Cold stress option highlights the days when severe frosts occurred. And the Heat stress option, in turn, reflects the risks associated with drought. Thus you can track the vegetation drawdowns on the plots with extreme temperatures.
Statistics and downloading
To expand the statistics and perceive the NDVI index of your field use the small panel above the analytics window. Statistics can be displayed in hectares or percentage terms. Using this panel you can download the NDVI map in .tiff or .shp formats as well. Shape format will provide you with the pixel-by-value NDVI at each point of your field and TIFF format will give a regular image with the NDVI applied. Three-dot menu switches from NDVI to RGB composite i.e. natural color which is not distorted by anything.
