This was a first attempt to fix the border between the Province of South Australia and the Territory of New South Wales. The paper will consider the history of Tyers’ original mark (Tyers’ Arrow) and detail a modern day search for it using GPS technology. It will also consider the background, training and subsequent career of Tyers. The paper will address the issue of survival of Tyers’ original mark of his 1839 survey and detail the field investigation to locate it. The paper will reach certain conclusions on the employment of GPS technology in historical survey research and the location of the South Australian - Victorian Harder based on Tyers’ survey. It will also consider the contribution to society by Tyers. The paper will have the basic structure of Introduction, Background, Findings, and A Brief Biography of Charles J Tyers, Conclusion. Acknowledgments and References. It will be illustrated with maps, photographs and Tyers’ original sketches.","PeriodicalId":119818,"journal":{"name":"Australian Surveyor","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2003-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128243851","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}

Australia is a federation of states and operates separate cadastral systems in each state and territory. The primary objective for each system is the same; to underpin effective land transfer and land registration within a sound land administration system to support an active land market. The paper explains the essential practices of the cadastral system including processes of land transfer and registration and the roles of professional supporting bodies for maintaining standards, quality and operability. Land information and especially ‘spatial’ information are increasingly required to contribute to decision-making in an evolving environmental and information conscious society. These demands raise the importance of the cadastre underpinning spatial data infrastructures.","PeriodicalId":119818,"journal":{"name":"Australian Surveyor","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2003-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113968668","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}
