2nd International Conference on Geoinformatics and Data Analysis (ICGDA2019) was held in Prague, the Czech Republic during March 15-17, 2019. The conference is supported by many universities and research institutes. Many professors play an important role in the successful holding of the conference, so we would like to take this opportunity to express our sincere gratitude and highest respects to our keynote speakers and reviewers. They have worked very hard in reviewing papers and making valuable suggestions for the authors to improve their work. We also would like to express our gratitude to the external reviewers, for providing extra help in the review process, and to the authors for contributing their research result to the conference. Special thanks go to our publisher. At the same time, we also express our sincere thanks for the understanding and support of every participant. Owing to time constraints, imperfection is inevitable, and any constructive criticism is welcome.
