Package: geosam 0.1.2.9000

geosam: Geospatial Image Segmentation with SAM3

Native R API for geospatial image segmentation using Meta's Segment Anything Model 3 (SAM3). Provides tidyverse-friendly interfaces for detecting objects in satellite imagery using text prompts, point prompts, and exemplar-based detection. Features open-vocabulary object detection powered by SAM3's text prompting. Built-in support for downloading satellite imagery from Mapbox, Esri, and MapTiler.
