Ndvi2Gif Tutorial#
Welcome to the comprehensive tutorial for Ndvi2Gif, a Python library for multi-seasonal remote sensing analysis with Google Earth Engine.
What is Ndvi2Gif?#
Ndvi2Gif is a powerful remote sensing analytics suite that simplifies access to global satellite data through Google Earth Engine. While its name highlights the ability to create seasonal GIF animations, the true power of this tool lies in its capability to compute and export pixel-wise statistics for any region on Earth, across any time span covered by supported remote sensing datasets.
Key Features#
🛰️ Multi-Sensor Support: Sentinel-1/2/3, Landsat 4-9, MODIS, ERA5-Land, CHIRPS (7 platforms)
📊 88 Variables: 40+ vegetation indices + 47 ERA5 climate variables + CHIRPS precipitation
🌡️ Climate Analysis: Temperature, precipitation, soil moisture, radiation, wind (1950-present)
🤖 Machine Learning: Supervised and unsupervised land cover classification (8 algorithms)
📈 Time Series Analysis: Trend detection, phenology metrics, climate statistics
🌍 Global Coverage: Process any region on Earth with intelligent data type handling
📤 Flexible Export: GeoTIFF, Google Drive, Earth Engine Assets
🎨 Visualization: Automated GIF generation and interactive dashboards
