## Description

Leafmap is a Python geospatial visualization library designed for creating interactive maps and performing geospatial analysis within Jupyter environments. It provides a comprehensive set of tools for building interactive map interfaces, browsing and visualizing SpatioTemporal Asset Catalog items, and connecting to PostGIS databases for spatial data rendering.

The project distinguishes itself through a backend-agnostic rendering system that allows users to switch between different mapping engines while maintaining a consistent API. It features specialized capabilities for Cloud Optimized GeoTIFF rendering and a STAC data browser for discovering and retrieving cloud-native geospatial datasets.

The library covers a wide range of analytical and visualization areas, including remote sensing imagery classification, temporal data animation, and comparative map analysis using split-panel views. It also includes utilities for thematic map generation, vector data conversion, and the extraction of building and fire-related statistics.

Interactive maps can be exported as standalone HTML files or embedded directly into Streamlit web applications.
