An assessment of smartphone and low-cost multi-GNSS single-frequency RTK positioning for low, medium and high ionospheric disturbance periods
The emerging GNSSs make single-frequency (SF) RTK positioning possible. In this contribution two different types of low-cost (few hundred USDs) RTK receivers are analyzed, which can track L1 GPS, B1 BDS, E1 Galileo and L1 ... -
Usability of Online Virtual Geographic Environment for Urban Design
Collaborative Virtual Geographic Environment (CVGE), a technology derived from Virtual Reality (VR), is today becoming widely and freely available. This technology has potential for use in the field of 3D urban planning ... -
An exploratory survey method for archaeoastronomy, applied to standing stones at the Hauviri and Taputapuātea maraes, Ra'iātea
Polynesia has a vast area, and surveys are few and unsystematic. Rapid, low-cost and personnel surveys are needed to identify cases that merit an in-depth treatment. However, surveying options are limited, especially where ... -
Tenuous Foundations: Historical Lessons for Modern Land Agreements
The past decade has seen a wave of land leases, sales and concessions unparalleled since colonial times. Concurrently, many countries are embroiled in ongoing remedial and restitutive work over historical land leases, sales ... -
Precession Issues in Polynesian Archaeoastronomy
Latitude and azimuth determination were crucial for Polynesian navigators, supplemented by techniques such as observations of swells, birds and expanded landfalls. Longitude could only be determined by dead reckoning. ... -
The role of control network in the accuracy of underground laser scanning surveys
Terrestrial laser scanning is used in various fields with numerous applications, one being the documentation of heritage sites. Often scans will be georeferenced with respect to a real-world coordinate system. This is done ... -
The Influence of Technology on the Land Surveying Profession
Land surveying has grown from a technical occupation into a profession. This study traces the rise of professions and the criteria that defines the requirements for an occupation to be granted such status. It then ... -
On the Multi-GNSS RTK Positioning Performance in New Zealand
With the advent of new Global Navigation Satellite Systems (GNSSs), multi-system, multi-frequency precise real-time kinematic (RTK) positioning can potentially be possible anywhere, at any time. The satellite constellations ... -
Surveying in South Africa: Coordinate vs monument cadastre
The article is an extract from correspondence between an Otago Surveying lecturer and a graduate who worked in Christchurch, New Zealand, and then moved to South Africa. Underlying the dialogue is a critical comparison ... -
Geographic Vector Agents from Pixels to Intelligent Processing Units
Spatial modelling methods usually utilise pixels and image objects as the fundamental processing unit to address real-world objects (geo-objects) in image space. To do this, both pixel-based and object-based approaches ... -
Splitting the atom of communal land tenure, with specific reference to Māori freehold land.
This article begins by contextualizing Māori Freehold Land (MFL) within a wider global debate on communal land that is in transition to more individualised forms of tenure. A comparison is made between Ngai Tahu MFL and ... -
An Alternative Cadastral Survey Dataset for New Zealand.
This paper assesses New Zealand’s system of electronic record-keeping (Landonline) in the light of recent technologies and data-processing capabilities. A prototype cadastral survey dataset is put forward for the purpose ... -
Between the Lines: the spirit behind land agreements
Land agreements negotiated between British authorities and indigenous groups were part and parcel of colonial expansion. Although current interpretations of the historical agreements which formed the basis for European ... -
Communal land tenure: can policy planning for the future be improved?
In developing Geomatics for Africa, communal land tenure must be among the most intractable of the issues faced. This paper seeks insights into likely communal land policy priorities in Southern Africa by contrasting issues ...
