ISPRS ISAC - International Science Advisory Committee

The ISAC has been established to support the Council and the ISPRS General Assembly in identifying and addressing important science and technology (S&T) trends which impact the scope of the ISPRS Commissions and the activities which should be addressed by ISPRS Working Groups.

In general, ISAC members are appointed as of January 1 following a Congress year and they serve a full term, i.e., until December 31 of the next Congress year. However, necessary changes of members are possible with the approval of the President. Membership is renewable but no person may serve more than three Congress Terms. No two members of ISAC shall be affiliated with the same institution. Members of Council and TCPs shall not be ISAC members.

The ISAC is to ensure that ISPRS S&T activities are in proper balance and cover the breadth of the Society's S&T mission.

ISAC Terms of Reference

  • Identify and prioritize scientific and technologic (S&T) trends which will impact the S&T activities of the Society and recommend actions to ISPRS Council.
  • Facilitate excellence in scientific research and development and the use of proper and appropriate technology by evaluating and refining S&T Resolutions proposed in advance by ISPRS Member Organizations and Commissions for approval by the quadrennial ISPRS General Assembly.
  • Collaborate with the ISPRS Council to formulate Resolutions for ISPRS General Assembly approval which will ensure that ISPRS is at the forefront of the S&T in the photogrammetry, remote sensing and spatial information sciences and covers the full breadth of the Society s mission.
  • Review proposed Working Groups Terms of Reference with Council and identify S&T gaps and overlaps and recommend corresponding fills and consolidations.
  • Evaluate inputs recommended for changing the overall scope and direction of S&T activities in the Society and advise Council accordingly.
  • Suggest collaborative S&T activities with other international societies and intergovernmental bodies to foster cooperation on the inter-disciplinary boundaries.
  • Propose worthy candidates for recognition and awards
