The Ministry of Defence of the Republic of Croatia, with the project "Military Geoinformation System - VoGIS" started to build a unique geoinformation system for the Ministry and Armed Forces. This system will be in accordance with Croatian and international geoinformation standards and will fully conform to the NATO standards. According to the Preliminary Design, the goal of the VoGIS is the implementation of a geoinformation system that will be the basis for development of all further activities in domain of military spatial data, with special emphasis on creation of military cartographic database and military maps, along with the fulfilment of the Partnership Goals. VoGIS is based on the Croatian Topographic Information System made by the CROTIS data model. In the first phase of the project, the object data model of the basic military topographic database is developed. In the second phase, the original conceptual design of the system is developed and the whole cartographic production workflow based on spatial databases is developed and implemented. The concept encompasses standardization of collection of special "military" content with upload into a basic topographic database, design of cartographic database model, map generalization, sheet line system, map design, production and printing.
