Abstract :
The paper gives the description of some components of the information-modeling
system developed to predict floods. The scales and formats of the required cartographic in-
formation are analyzed. The composition and structure of the problem-oriented database for
data storage and processing in the information-modeling systems is presented. The database
designed as a “star” schema based on DBMS PostgreSQL is proposed. Tools for the construc-
tion of interactive maps of flood zones with the use of standard service of Google maps have
been created. The maps allow to identify flood zones at various probability of exceedance, to
get the information on areas and details of the flooded territories as well as to make science-
based decisions on flood protection.
