satellite image dataset of India for field delineation

Dear Team,

We would like get your inputs on the satellite image dataset of India specific to delineated farm lands.

We are working on building some deep learning models which requires satellite images of delineated farm lands of india as training images.

It would be of great help, if you can help us here.

Hi @swagotaberasarkar

Could you please specify what are you after? It is not clear if you are looking for satellite imagery, or for a (vector) dataset of fields in India.

For the first one, you are in the right place: you can use Sentinel Hub services, eo-learn and sentinelhub-py to get the imagery of your area of interest for the time window of choice for the data collections SH services provides.

For the latter, unfortunately, we do not have any data for India. The model we’ve prepared for field delineation (see also accompanying blog post) was trained on high quality reference data (GSAA data provided by national paying agency, containing vector data of declared agricultural fields).

Unfortunately, such data is rarely open, and often does not exist. If that is the case for you, you have two possible paths forward (possibly more, but these two come to my mind):

  • create the dataset yourself by manually drawing polygons (beware: this is costly and quite difficult to do, but done properly you can get very high quality data)
  • train the model someplace else - where you can get reference data - apply it to your AOI, and then fine tune the model by adding manually drawn polygons (only) where the predictions are most wrong

I hope this helps. Kind regards and keep us posted.
