**Preface to "Integrated Applications of Geo-Information in Environmental Monitoring"**

The aims of this Special Issue (SI) of Remote Sensing are to demonstrate the state of the art in the development and application of geo-information technology, including optical and radar remote sensing, GIS, GPS, and computing systems in various environmental fields. Motivated by the high-quality presentations at the International Conference on Geo-information Technology and its Applications (ICGITA 2019), this book covers the up-to-date research in land cover change and desertification analyses, geo-disaster risk and damage evaluations, mining area restoration assessments, the improvement and development of algorithms, and coastal environmental monitoring and object targeting. This book can be used as a reference for graduates and scientists in environmental sciences, disaster managers, urban planners, and big data miners. The Guest Editors are grateful to the authors for their contributions of high-quality studies, and, specifically, to the MDPI team for their effective assistance and cooperation. Without their devotion and support, it would have been impossible to publish this book.
