Agro-geoinformation, the agricultural-related geo-information, is the key information in the agricultural decision-making and policy formulation process. The Agro-Geoinformatics, a branch of geoinformatics is the science and technology about handling digital agro-geoinformation, such as collecting (mainly through remote sensing and field investigation), processing, storing, archiving, preservation, retrieving, transmitting, accessing, visualization, analyzing, synthesizing, presenting, and disseminating agro geoinformation. Recent advances in geoinformatics and IT have created new opportunities and challenges in applying agro geoinformatics to agriculture monitoring, assessment, and decision-making. This International Conference on Agro-Geoinformatics is a major venue for professionals and students to exchange ideas, research results, professional experiences, and future visions in the fields of geoinformation science, remote sensing, and their applications in agriculture.
