Recognizing trends to develop national spatial data sets, if a national cadastre is ever to be considered, a basic requirement will be a unified national law regarding land ownership. In turn this will require a unified approach to the issue of adverse possession of registered title land and particularly adverse possession of part of a land parcel, which is, in the authors’ view, a major obstacle in achieving this vision.With this in mind a review is given of current Australian (particularly Victorian and NSW) schemes regarding adverse possession of part of a registered title land parcel to indicate those fundamental differences requiring possible resolution.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122891273","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}

Rather than record a single height difference per instrument set-up, four backsight measurements and four foresight measurements are taken and stored on board the instrument. In post-processing, the four height differences per set-up are accumulated separately along a section to give four one-way section height differences. A practical example demonstrated that the use of multiple height differences per one-way section greatly improves the precision of the adjusted elevations in a network adjustment. Also, the weighting of the observations according to the section-by-section precision of the measurements produces a more realistic precision of the adjusted elevations as the precision is not longer solely distance dependent.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126376965","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 raised the question whether broad trends are, despite varying national pressures and priorities, the primary determinants of cadastral change. This paper presents an alternative view: that the primary determinants of cadastral change are internal (national) and conflict among stakeholders over the land issue, expressed through State action, is a major motor of change. Attempts to explain cadastral reform based on broad global trends tend to slight over the different national trajectories. A brief case study on the development of the cadastre in early Singapore is used to illustrate the complex dialectics between society and cadastral development.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123169220","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}

It is also argued that the horizontal coordinate transformation should not include height information, since this forms an entirely different coordinate in another coordinate system.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125961903","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}

An evaluation is made of the accuracy of the DEMs generated by the JPL/NASA TOPSAR interferometric SAR system, by comparing them with an accurate reference DEM derived from the digital photogrammetric processing of 1: 25000 aerial stereo photographs. The terrain in the test site location was relatively flat, with a variation in elevation ranging from 29 m to 115 m. DEMs generated from the acquired radar data were rotated and translated to overlay the reference DEM, allowing an analysis of the achieved height accuracy. The errors measured over 4.5 km x 2.5 km were 3.9 m rms for C-band interferometry DEM and 12.9 m rms for L-band interferometry DEM. The background on radar and SAR image formation, the principles and applications of SAR interferometry as well as the key factors that presently limit this technology are also presented.","PeriodicalId":222452,"journal":{"name":"The Australian Surveyor","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128762883","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}
