The next webinar part of the Research Data Alliance Interest Group for Agricultural Data (IGAD)’s new Coffee Break initiative will take place on 27 October 2021 from 13:00 to 13:30 CEST. The webinar, titled Analysis of time series of Sentinel 1 and Sentinel 2 data – the new quality of information for Agriculture will feature Karel Charvat, from Plan4all

Satellite Crop Detection technologies are focused on detection of different types of crops on the field in the early stage before harvesting. Their classification is one of the key themes of the common agricultural policy within the initiatives of the European Commission. Currently, data obtained from Remote Sensing (RS) are used to solve tasks related to the identification of the type of agricultural crops and modern technologies in the issue of post processing  this kind of data sources. 

During this webinar, Karel Charvat will discuss the importance of the common classification methods for crops including: 

  • Supervised classification, which is the technique most often used for the quantitative analysis of remote sensing image data. At its core is the concept of segmenting the spectral domain into regions that can be associated with the ground cover classes of interest to a particular application. In supervised classification the user or image analyst “supervises” the pixel classification process. The user specifies the various pixel values or spectral signatures that should be associated with each class.
  • Image segmentation, which is defining object fields directly, can be considered as a more advanced method. Till now the method is working with Sentinel 2 and most of the solutions are working with data from one period. 

Registration is now open. Interested participants can register for the webinar here.
