Abstract text:
The paper aims to present the general framework of the spatial reference for geoinformation in the NE region of Romania, in order to have a unitary approach to joint cross-border projects with the Republic of Moldova in the field of risk management. Due to the multitude of spatial data sources involved in such projects and the processing of geodetic measurements on different reference surfaces, a distinct presentation of coordinate reference systems is required for horizontal, vertical and spatial positioning. In operating with these coordinate reference systems, there is an implicit need for coordinate conversions and transformations, which must be performed within acceptable precision level, according to the requirements of the project. Therefore, the paper outlines a practical guide in working with spatial data specific to different datums and map projections for this area. In the last part of the paper, the cartographic fund at national level corresponding to the official datums in Romania in the last decades is presented and finally, the framework for defining the spatial reference systems for cross-border projects is proposed.
