# Model Card for LandSegmenter

<!-- Provide a quick summary of what the model is/does. -->

This repo provides the weights for LandSegmenter, a task-specific Foundation Model (FM) for Land Use and Land Cover (LULC) mapping, characterized by high flexibility in both inputs (multi-band, multi-resolution imagery) and outputs (customizable category definitions), supporting both zero-shot inference and fine-tuning.

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->
LandSegmenter is the first LULC FM trained with LAS, designed with high flexibility to handle diverse input modalities and customizable category settings. It builds on [SAM2](https://github.com/facebookresearch/sam2)'s backbone for robust multi-scale spatial representation, further enhanced by multispectral features from [DOFA](https://github.com/zhu-xlab/DOFA) and high-frequency components for refined structural details. A text-based prompter derived from [GeoRSCLIP](https://github.com/om-ai-lab/RS5M), which takes class names as inputs, further strengthens its semantic understanding, enabling concept-aware and adaptable segmentation across heterogeneous data sources
