Working Group 5.2 - Reference Frame in Practice
Policy issues
Policy Issues include the following:
- Work to bring together all organisations involved in defining or using
reference frames to develop common approaches and avoid duplication. Such
organisations include FIG, IAG, ISO, groups of national mapping agencies,
other influential national agencies (such as the US DoD's NIMA) and
alliances of commercial organisations (such as Open GIS Consortium and the
European Petroleum Survey Group).
- Provide background technical information on relevant issues written in a
way that is accessible to the surveying practitioners.
- Develop an inventory of approaches to reference frame issues in different
countries (including transformation methodologies) that is accessible to
surveying practitioners.
- Examine how surveying practitioners are changing how they access the
reference frame, through less emphasis on networks of ground monuments and
more emphasis on Global Navigation Satellite Systems (GNSS) base stations.
- Examine the increased use of GNSS for height determination and the use of
geoid models etc for connection to local height datums.
- Examine the increasing role of aerial and space based imagery in the
realisation of reference frames.
