Conventionally, the crop monitoring is performed manually which is time and resource consuming. Since, it is not possible to collect the data from each and every farm, the collected data is not useful for farm specific advisory. The conventional methods are limited to mainly the crop acreage and monitor the impact of large scale calamities only. The lag time to collect information runs in months which hinders the timely policy intervention.
The satellite remote sensing has several advantage e. g. frequency revisit time, large area coverage and is capable of monitoring several variables (e.g. crop health, water stress, crop acreage, crop yield estimation etc.). The satellite data becomes available within few hours and the processed information becomes available within 1-3 days. The timely availability of information can help reduce the time taken for the policy intervention and provide in-time relief to farmers.
Aapah Innovations has developed models to estimate the crop variables by combining the data from different satellites to improve the temporal receptivity.
