Annotation: This article explores technologies and methods for updating GEODATA databases. The relationship of information in the GEODATA database with the worldview model is shown. The difference between updating a database and regenerating a GEODATA is shown. The rationale for creating and applying the new concept of “data upd ate buffer zone” is given. The content of remote space sensing methods is revealed. It is shown that the basis of space technologies is geoinformation modeling. The main requirements for information stored in a GEODATA database are summarized: informational and structural. The information requirement is formulated as the need to transform data into GEODATA and, accordingly, to allocate three components: spatial, temporal and thematic. A structural requirement has been formulated that consists in the structural consistency of GEODATA describing different objects. A formalized conceptual model of updating the GEODATA database in terms of se t theory and logical schemes is proposed. It represents a mechanism for building a new worldview based on an existing one.
