Dataset distribution
Description The dataset publishes crop heterogeneity (non‑uniformity) assessment data from the Automatic Field Monitoring System (ALNSIS). The algorithm uses pixel‑based classification and machine‑learning methods based on Sentinel‑1 and Sentinel‑2 satellite data to identify different crop types, growth stages and heterogeneity within crop fields. The analysis helps determine crop composition and detect possible issues such as weeds or uneven growth. Using the algorithm, the actual crop composition in a declared field can be determined – the percentage distribution of different crop types within the field is calculated. It is also possible to assess what share of the area is actually occupied by the declared crop compared to other crops or land cover elements. The dataset provides information on the applicant, the declared field (agricultural holding identification code, area, municipality and eldership) and crop areas determined by the algorithm, expressed as percentages of the total area. Data provider – National Paying Agency under the Ministry of Agriculture. For questions related to the data, please contact atverimas@stat.gov.lt.
