Commonwealth Association of Surveying and Land Economy (CASLE)

Mission


"We are committed to the advancement of the profession of Surveying in the Commonwealth, and to the enhancement of the skills of Surveyors in the management of the natural and built environments for the common good."

  • Objectives

    CASLE was formed in 1969 as a federation of independent professional societies representing surveying and land economy in Commonwealth countries. CASLE is an organisation which is non profit-making in nature, and any monies raised, or any surplus monies made from its activities are deployed into activities which are intended to support its aims as set out in Article 2 of the Constitution.

  • CASLE and Sustainability

    CASLE believes that many of the problems facing the world in respect of the use of scarce resources may be mitigated by careful planning. Within the scope of the three professional fields, the education and experience of surveyors may be drawn upon to provide advice on the effective use of resources in new projects, and the long-term resource and cost consequences of planning, design, and construction decisions.

News and Updates


CASLE publishes a regular newsletter, reports of general assemblies and regional conferences and seminars, and information of interest to the profession, including advice on Education for Surveying and Land Economy.
