Five Decades of Mapping the Moon

This year, NASA is celebrating the 50th anniversary of the first crewed mission – Apollo 11 – landing on the moon. Besides that, this September it will be 60 years since the first unmanned mission – Luna 2 – reached the surface of the moon. Both of these milestones reflect the great contributions of the USA and the Soviet Union/Russia to space exploration, but they would not have been possible without spatial data. National Geographic has always been at the forefront of lunar mapping. At the time of the Apollo missions, crews relied on its hand-painted maps based on photos... (read more)

Galileo Satellites Down Since Friday 12 July

The European navigation system Galileo is suffering a major outage. The satellite network has been largely down since Friday 12 July due to a technical incident related to its ground infrastructure, as the EU agency GSA reports. The incident has led to a temporary interruption of the Galileo initial navigation and timing services, with the exception of the Galileo Search and Rescue (SAR) service. The SAR service - used for locating and helping people in distress situations for example at sea or mountains - is unaffected and remains operational. Due to the problems, all receivers are not able to pick... (read more)

New Usage-based Service Plans for Trimble Catalyst Enable Precise Positioning on Demand

Trimble has announced that its Trimble Catalyst software-defined GNSS receiver for Android phones and tablets is now available with a usage-based service plan: Trimble Catalyst On Demand. The new service plan is focused on satisfying the requirements of a growing number of industries and organizations who recognize the benefits of using high-accuracy GNSS technology in the field, but need a more flexible payment model. Trimble Catalyst On Demand provides scalable access to RTK-quality GNSS positioning using an affordable pay-per-use hourly pricing model in addition to the current Catalyst monthly plans. The new service also enables automated domain-level email address access,... (read more)

Tackling the Challenges of Road Construction

As new technologies emerge with the promise to increase productivity and efficiency, costing is one of the most important criteria in a project life cycle. Construction companies are seeking more effective and cost-efficient methods to complete their work as accurately as possible. (This story is brought to you by Satlab Geosolutions; Click here to download this case study) Based in Korat, Thailand, Khunnon Construction, a subsidiary of S.P.T Construction, focuses on superhighways, road and bridge constructions. These projects require precise accuracy. With that in mind, Khunnon Construction purchased the Satlab Geosolutions SLC multi-purpose GNSS receiver after being appointed as the main... (read more)

Taking Full Advantage of the Benefits of UAS Technology

Leveraging UAS technology across surveying and engineering sectors is demanding. The expectations of accuracy and accountability requires the best in expertise, methodology and equipment. Using the latest unmanned aerial system (UAS) photogrammetric hardware and software, surveyors are now capturing millions of survey measurements on the ground, where they would previously have measured only hundreds. It is essential to have the best-quality equipment, software and workflows to ensure this data is accurate, robust and defensible for professional use. Geosyntec is a leading consulting and engineering firm that works with private and public sector clients to address new ventures and complex problems... (read more)

Sensor Fusion for Precision Agriculture

Low-cost Lidar Camera System without GNSS
Precision agriculture has considerably benefited from the use of unmanned aerial vehicles, often combined with active ranging sensors like Lidar to gather information from underneath the crops, but existing systems are relatively expensive for the farming sector. In this project, researchers in Canada have used an integrated sensor orientation method for the local referencing of Lidar measurements. Their approach is based on loosely coupled, image-aided inertial navigation in which the pose of the camera replaces the GNSS measurements. The result is a low-cost solution that is useful for capturing topographic data of inaccessible areas as well as in GNSS-denied environments.... (read more)

Septentrio Releases New High-precision GNSS Module

Septentrio has announced that the Mosaic development kit is available for testing and integration. Mosaic is Septentrio’s most compact next-generation, high-precision multi-frequency GPS/GNSS module. This receiver brings precision and reliability of high-end multi-frequency GNSS to mass-market applications. It is designed to fit into the assembly line process, which allows Mosaic to be favourably priced for high volumes. Its light weight and low power consumption helps extend battery life of robotic devices, increasing operation time and efficiency. This makes Mosaic ideal for applications such as robotics, automation, telematics and wearables. “We see a growing demand for reliable high-precision positioning,” said Chris Lowet,... (read more)

Mapping a University Campus in Brazil

Creating Indoor and Outdoor Maps for a Routing Application
At universities, facility managers and other support staff need easy access to data, including geodata, for maintenance, safety measures or routing of students, staff and visitors. A responsive geodatabase containing detailed and up-to-date information on roads, the interior and exterior of buildings and other objects is a key tool in that context. The authors of this article describe a pilot project conducted at a university campus in Curitiba, Brazil, aimed at creating outdoor maps using unmanned aerial system (UAS) photogrammetry as well as indoor floor plans, and demonstrate the possibilities of the database with a routing application. The Federal University... (read more)

Standards Are a Great Help for Establishing Land Administration

GIM International Interviews Christiaan Lemmen
In 2017 Dr Christiaan Lemmen, a former contributing editor of 'GIM International', was appointed as professor of land administration modelling at Twente University’s Faculty ITC for Geo-Information Science and Earth Observation. He is the leading designer of the ISO 19152 international standard for geographic information – Land Administration Domain Model (LADM), the second edition of which has been in development since 2018. In this interview, he discusses the importance of LADM standards, poverty and tenure security, and the long and winding road to put well-functioning land administration in place in developing countries. The Land Administration Domain Model is actually an... (read more)
