The aim of the article is to present the role and activities of the National Secretariat GEOSS/GMES (NS). Existence of the NS was declared by the Czech Governmental Resolution No. 229/2009. This resolution requires activities of two ministries – the Ministry of the Environment and the Ministry of Education, Youth and Sports to coordinate Czech activities related to international programmes GEOSS and GMES. The goal of GEOSS and GMES is building up an integrated and sustainable system by sharing and providing information services on the environment, especially those based on Earth observation and remote sensing technologies. The article explains the Czech approach to the coordination of GEOSS/GMES. The coordination is necessary for efficient exploitation of the first-emerged services and also for expanding information to the user´s community. The NS Work Plan 2011 was introduced at the beginning of this year and some goals have already been achieved.
