NATIONAL REPORT FOR THE 17TH ISPRS CONGRESS, ZIMBABWE 1992
by Mr K Philip (Committee Chairman) & Mr T Heath (Committee Member)
of the Zimbabwe Society for Photogrammetry, Remote Sensing & Cartography
Dr H Kaufmann, Technical Expert in the National Remote Sensing Facility
Mrs K Rogers Chairperson of the National Committee for Land and Geographic Systems,
and Mr D P Goodwin, Lecturer, Dept of Surveying, University of Zimbabwe
This First National report overviews the nation’s activities in photogrammetry and remote sensing and gives some details
of the relevant institutions. Zimbabwe's inaugural year of membership to ISPRS coincides with the Department of the
Surveyor-General's 100th anniversary, indicating the long involvement with surveying and mapping. This government
department is responsible for national topographical mapping but air photography is contracted out to the commercial
sector who also satisfy the demand for large scale engineering mapping and orthophotomapping. Elements of
photogrammetry and remote sensing are taught within diploma courses at the Harare Polytechnic and to a more
advanced level in the BSc Survey course at the University of Zimbabwe. Short courses in remote sensing are done at
the University of Zimbabwe and the NRSF with co-operation from the Department of the Surveyor-General. Much
interest in GIS has been generated and this led to a multi disciplinary National Committee for Land and Geographical
Information Systems (LIS/GIS) being established. It currently operates under the aegis of the Surveyor General. In some
organisations a start has been made to the collection of data in a digital format. The Zimbabwe Society for Photogrammetry,
Remote Sensing and Cartography (ZIMPRAC) which is the body representing ISPRS in Zimbabwe and the compiler of this
report, is a society that facilitates the meeting of people who are practising or interested in the mapping sciences.
