awebgis-small

Model Description

awebgis-small is a fine-tuned T5-small model engineered for Autonomous Web-based Geographical Information Systems (AWebGIS). As the most capable variant in the AWebGIS model family, it delivers superior performance for complex geospatial queries while maintaining efficiency suitable for web deployment. The model transforms natural language instructions into precise geospatial function calls, enabling sophisticated autonomous GIS operations.

This model is optimized for handling intricate geospatial tasks that require deeper understanding and more nuanced processing, making it ideal for applications that demand higher accuracy and can accommodate slightly larger model sizes.

How to Use

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("mahdin75/awebgis-small")
model = AutoModelForSeq2SeqLM.from_pretrained("mahdin75/awebgis-small")

# Example usage
input_text = "Create a buffer zone of 10km around all hospitals, then find intersections with residential areas and calculate population density"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs, max_length=128)
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
