Google Earth Engine vs MapServer

Google Earth Engine combines satellite imagery and geospatial datasets for large-scale analysis of changes, trends, and surface differences. Its public archive holds more than eighty petabytes of geospatial data and over thirty years of historical imagery, with additions made daily. The web-based Code Editor includes JavaScript editing, map visualization, interactive queries, geometry drawing, task management, API reference, and Git-based script management. Python and JavaScript APIs also support local client-library use. Earth Engine integrates with Google Cloud and can load BigQuery tables, run BigQuery queries, and export results there; the maker also describes interoperability with tools including TensorFlow, PyTorch, Spark, and Pandas. Shareable Apps let stakeholders explore analyses through interactive interfaces. Uses include remote sensing, climate analysis, natural resource management, and sustainability. Eligible groups may qualify for restricted noncommercial use at no cost; commercial and government operational customers are charged. Individual & SMB Basic and Enterprise Basic cost $500 per month; Enterprise Professional costs $2000 per month. Usage-based storage and compute charges are also listed.
