Special Issue on the Recent Trends of Geo AI Techniques for SDGs

<正>Reliable and up-to-date geospatial data plays a fundamental role in Sustainable Development Goals（SDGs） monitoring.Aiming to providing such geospatial data,numerous algorithms,solutions and frameworks have been developed in recent years.Among others,Artificial Intelligence （AI） based techniques have been widely used for the tasks of processing geospatial data.Nowadays,this topic is blooming so fast and to a vast extent in the field of Geomatics that a new subdomain seems to arise,namely GeoAI[1-2].Even for a very quick and brief glance inthe Internet,people can find a lot of applications,projects,blogs and research articles about GeoAI,whereas new approaches to GeoAI have been proposed and tested.
