Photogrammetry Tool for UAV Land Surveying Missions

Before the introduction of small unmanned aerial vehicles (UAVs) for aerial photogrammetry, planes, helicopters and metric cameras were used. Aerial mapping projects were often not only costly, but also complex due to the images being taken from high altitudes. UAVs have provided more affordable and faster aerial mapping solutions. When it comes to planning survey missions for small UAVs, UgCS is suitable software for the job. It supports most UAV platforms and provides useful tools such as a photogrammetry tool and an image geotagging tool. The photogrammetry tool in UgCS (designed by SPH Engineering) allows creating and flying photogrammetry missions... (read more)

Geomatics and Surveying in Support of Land Administration

Implementing Tenure Security for All
Today’s geospatial technology means that land administration systems can increasingly be implemented for the benefit of all. It is now possible to conceive approaches to capturing the unrecorded geometry of boundaries for the billions of unrecognised land interests or spatial units. In addition, new approaches are becoming apparent for the maintenance of collected data. Examples from the field show that we’re well on the way to responding to the challenge. From a geomatics and geoscience perspective, many tools are already available to support development, but further steps are needed to operationalise them at scale. Read on for an article investigating a... (read more)

Scanner Goes Gyrocopter Surveying

A South African company is pioneering the latest laser scanning technology with plans to mount high-speed scanners on a variety of mobile platforms including a gyrocopter, 4x4s and even a golf cart. Supplied by 3D Laser Mapping, the RIEGL VZ-400 will be used by Land and Marine Surveys, a survey company based in Umhlanga in KwaZulu-Natal, South Africa, for traditional terrestrial scanning, mobile data capture and the production of design-quality graphics.     "Our R&D on mobile scanning goes back to 2008, where we had previously tried other devices on our survey vessel, the back of our utility van as...

Thai Surveying Satellite Theos

Thailand's first geography-surveying satellite ''Theos'' is expected to be launched into orbit October 2007. The six-billion-baht satellite, officially called Thailand Earth Observation System (Theos), is being built by France-based Astrium S.A.S. Equipped with two cameras, the satellite is expected to help the government better plan natural disaster management as it will be able to help monitor areas prone to floods and coastal areas at risk of being hit by tsunami waves. ''The most important benefit to us is the development of Thai personnel in the area of space technology,'' Science and Technology Minister Yongyuth Yuthavong said. More than 20 Thai... (read more)

Mailbox - Surveying the Bahamas

GIM Statement In order to address the personnel shortage in geomatics, a company involved in the field has a corporate responsibility to promote careers in geomatics and help schools and universities attract more students. Pushpa Gamage, Sri Lanka: "It is a wise decision, since the Geomatics field is still limited to higher education only." Anim Vincent, Ghana: "Geomatics should be introduced into our secondary schools, especially in Ghana." Garfield Young, UK: "Marketing and very active promotion of the exciting discipline of Geomatics is critical for its growth. Early intervention is important, such as the introduction of spatial-science courses in pre-tertiary... (read more)

Surveying and Positioning Systems

North Group
The world of surveying and positioning is experiencing an amazing transformation that began just recently, and goes hand in hand with the superior push in technology democratisation due to the popularity of consumer and professional hand devices. Almost any phone is now more powerful than our first desktop computers and satellite positioning seems to be permeating into everything from locating friends to autopilot planes and cars. North Group has experienced this change in technology since its first totally automated truck fleet management system was put to work in 2000 in Europe, USA and Mexico. The hardware and communications involved in... (read more)

Land Administration in Ethiopia

Model for Establishing Tenure Security in Other Countries
A Land Administration System (LAS) consolidating rights to rural land has been developed in the Amhara Region in Ethiopia. Since the start of the project in 2002 over 2.4 million possession-rights have been registered and over 1.3 million households given certificates. The approach, which has been taken as a model for other regions in Ethiopia, could also be a model for establishing tenure security in other countries. Positive outcomes The Environmental Protection, Land Administration and Use Authority (EPLAUA) in the Amhara Region of Ethiopia is responsible for the development and implementation of the Land Administration System (LAS) there, activities financed...

Global Land Survey 2010

From last June, the ScanEx Research and Development Center takes part in the international project Global Land Survey 2010. The GLS Program is aimed at building global satellite Earth coverage by 2010 and is implemented on the basis of the initiative introduced by NASA and USGS. The satellite coverage will be built on the basis of Landsat 5 and 7 data for the purpose of investigating impacts of human activity as well as natural and climatic changes on Earth.   Possibility of further comparative analysis of multitemporal images will be ensured by data collected over the 36 years of Landsat...

UAVs Revolutionise Land Administration

In 2014, a joint publication by the World Bank and FIG noted that 75 percent of the world’s population do not have access to formal systems to register and safeguard their land rights. Therefore, there is an urgent need to build affordable and sustainable systems to identify the way land is occupied and used. The emergence of smaller and more affordable UAS technology, combined with recent advances in highly automated mapping techniques, offers a new tool and methodology for producing faster and cheaper spatial data. In turn, this can benefit land administration agencies and help to secure property rights for... (read more)

Secure Land Tenure

Land Rights for Women and the Poor
Success factors in secure land-tenure policy include robust collection of geospatial, anthropological and sociological data, acknowledging customary rights and land rights of women and the poor, and law enforcement capable of penetrating urban and rural areas and avoiding conflicts between statutory and customary law. The authors address these issues for developing countries and present their geospatial technology-based, in-house developed methodology for establishing secure land tenure.<P>   Security in a customary land-tenure environment first of all requires capturing large volumes of data in a form that is retriev­able, searchable, reliable and dur­able. Or, as Grover, Törhönen and Palmer state: ‘Securing and... (read more)
