    Like the network transportation and the communication, the

    Geographic information becomes an indispensable element for

    economicdevelopment.TheTunisiangovernmenthasdecided to

    organize this sector in order to avoid the problems mentioned

    aboveby:

    III. NATIONALGEOSPATIALINFOSTRUCTURE

  • Geographical names constitue an integral part of the geospatial information.

    Tunisia has participated to UNGEGN meetings since 1982, through the Office of Topography and Cartography, main national mapping agency at that time.

    A restricted Geographical Name Committee was created in 1983 within OTC and held many meetings and workshops between experts from OTC and the concerned organizations, like the Geographic and Hydrographic Services of the Ministry of Defense (DSGHA, an institution merged to CNCT in 2004) and the Center of Economic and Social Studies and Researches (CERES), to study Beyrut 1972 transcription system before its implementation in the updating of its topographic maps .

    During the last 2 years and boosted by the UNGEGN recommandations and resolutions, the NMRC has presented a project for the creation of a National Toponymic Commission, Which project is pending approval.

    Geographicalnamesactivities

  • NMRC is regularly and actively participating to all meetings and workshops related to the field either organized by ADEGN (Arabic Division of Experts on Geographical Names) , one of the 23 UNGEGN linguistic Divisions, or by UNGEGN. Without forgetting its participation to special meetings and workshops organized by UNECA/AUC to promote Toponymy in the African continent.

    At the national level NMRC participated In April 2007 with the Regional Centre of Remote Sensing for North African States (CRTEAN) and the African Organisation of Cartography and Remote Sensing (OACT ) to the organization of the 2nd Arabic seminar on the standardization of geographical names where a training course in toponymy was given by UNGEGN experts.

    Mme Naima Friha from the NMRC is the Vice Chairperson of the UNGEGN and also the Vice Chairperson of ADEGN
