Biography
Ms Dragica Pajić graduated in 1993 as geodetic engineer at the Department for geodesy on the Faculty of Civil Engineering of the University of Belgrade. She joined Republic Geodetic Authority in 1994 working in local cadastre office. She has been actively involved in the INSPIRE implementation in Serbia since 2008, performing activities on development strategic framework, regulation related to geoinformation, spatial data management and geoportal maintenance, participation in international SDI projects as well as coordination of national activities on data and service production under the EuroGeographics umbrella.

Various spatial data is collected, processed and disseminated to users thanks to the implementation of the IGIS project in Republic Geodetic Authority throughout transfer of knowledge and expertise by the project partners IGN - France International and Airbus Defence & Space. The outcomes of the project significantly contribute to the building of NSDI and implementation of the basic INSPIRE components. The implemented technical infrastructure comprises flexible, fully scalable and interoperable components well suited for the needs of public authorities and business in Serbia. In doing so, and by using a comprehensive multi-source of data, it enables a variety of spatial data to be produced such as: satellite and aerial imagery; orthophoto satellite mosaics for the national wide coverage; true-orthophoto for the two biggest cities and orthophoto for 90 cities; digital elevation models; highly accurate digital terrain model for the flood prone area; 3D topographic data base; maps derived by application of remote sensing technologies for environmental, agricultural and risk management purposes etc. Urgent satellite imagery was acquired for the areas affected by the devastated flood in May 2014 for the western part of Serbia. The supplied imagery is analysed by using remote sensing methodology for obtaining the information on flooded areas, soil saturated by water and potential landslides. Ministries and other public authorities used the imagery with additional mapping data within emergency management to assess the impact and the extent of damages caused by floods. Additionally, Republic Geodetic Authority cooperated with private sector to provide geoinformation acquired by unmanned aerial vehicles for the most affected sites by floods and landslides. The technical infrastructure for optimised storage and data management allows access to data and services via the web portals. In such a way, smooth data sharing is enabled between public authorities that significantly underpins implementation of the INSPIRE network services in practice. Paper describes concept, key components, products and services as well as challenges and outcomes of the implemented IGIS project.
