As part of that process a number of questionnaires have been circulated to obtain comments and suggestions from the members as to which services they feel the Institution should be providing, how well those services are provided as well as other general issues, such as structure, representation and the level of fees. In August 1998 two questionnaires were circulated to the members of the Institution, to permit updating of the information held by the Institution and develop a more accurate profile of the membership as well as gauge the members' views on a range of topics. This paper summarises the responses from the membership.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126066528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without doubt the most comprehensive transformation strategies will require extensive re-adjustment of vast volumes of survey control data. This is true whether considering transformation of the survey control data itself or in the preparation of distortion models for the transformation of compiled data stored in spatial information systems. In light of the size of the transition task it is likely there will be more adjustments carried out in the next few years than previously required. The obvious need is for a process to consistently undertake the necessary adjustments in a rigorous and efficient manner. A newly developed technique known as Dynamic Network Adjustment offers the potential to satisfy this need and to maintain these networks once the initial readjustments have been completed.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129114672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach avoids post-survey adjustment of the GPS-AUSGEOID-derived heights in order to align them with existing AHD control. Alternatively, of course, the AHD could be redefined and readjusted such that it is more coincident with the classical geoid, thus allowing the use of a pure gravimetric geoid model in the height transformation. However, the cost and inconvenience associated with implementing a new national vertical datum in the near future render the proposed approach a more practical option in the interim.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133832170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
