Geography as the Organizing Grammar of Geospatial Models
Rajiv Ranjan, Shashank Tamaskar
GeoAI increasingly produces reusable Earth representation s, physical forecasts, multimodal systems, and reasoning a gents. Their progress exposes two distinct limitations. Geo gra…
AgroBench: A Reproducible Multimodal Benchmark for Weakly Supervised Crop Yield Learning from County Statistics and Pixel Observations
Udaiveer Singh, Rajiv Ranjan, Shashank Tamaskar +1
Reliable agricultural yield statistics are typically reported at coarse administrative scales, whereas modern geospatial machine learning methods require spatially explicit, pixel…
SPEAR NeXT Causal Latent Forecasting Across Multiple Horizons for Spectral Temporal Earth Representation Learning
Rajiv Ranjan, Udaiveer Singh, Shashank Tamaskar +1
Earth observation is inherently dynamic, yet temporal information in many foundation models is learned through reconstruction, invariance, or retrospective sequence summarization.…
CGMap: A Geospatially Aware Deep Learning Framework for Crop Gap Mapping Using UAV
Karan Sharma, Rajiv Ranjan, Dinesh Kumar +1
In India, crop germination is primarily monitored by visual inspection and manual counting, which are prone to errors, despite their crucial role in determining eventual yield pote…
STS-NET: Spatio-Temporal Stress Network for Self-Supervised Crop Stress Detection using Satellite Image Time Series
Pradeep Dalal, Rajiv Ranjan, Sushil Ghildiyal +2
Early and accurate detection of crop stress is essential to improve agricultural productivity and ensure global food security. However, collecting a large labeled crop stress datas…
Evaluating Sugarcane Yield Variability with UAV-Derived Cane Height under Different Water and Nitrogen Conditions
Rajiv Ranjan, Tejasavi Birdh, Nandan Mandal +2
This study investigates the relationship between sugarcane yield and cane height derived under different water and nitrogen conditions from pre-harvest Digital Surface Model (DSM)…
