The paper gives approaches to the use of existing LIDAR (Light Identification, Detection and Ranging) scanning systems to survey the Moon and other plan-ets. The study conducted is based on available domestic and foreign experience in using aerial (ALS), mobile (MLS), and ground (GLS) laser scanners. Issues of using space scanning systems for spatial and technical monitoring are also considered. The formulated problems of the creation and operation of space-purposed scanning systems allow determining the priority lines of applied scientific studies in this subject area.

Surface reconstruction of objects using photogrammetry and terrestrial laser scanning systems (TLS) has been a topic for research for many decades, especially for culture heritage data recording. Recently, many advances into these systems are now available in the market, which give the availability of collecting a huge number of geo-referenced 3-D points covering any object surface. Due to speed and efficiency of data acquisition by means of terrestrial laser scanners, researchers and designers can select the reliable technique, depending on their application, that can be complete to give good results for the complex surfaces such as heritage objects. As Grand Egyptian Museum (GEM), located nearby the Giza Pyramids, is set to open by 2020, which considered as the largest museum from its type all over the world, with a huge area covered about a half million m2 . GEM is proposed to be a unique museum all over the world for presenting a huge number from old history Egyptian artifacts. Consequently, there is a vital need for building a huge digital database containing complete information for this large number of artifacts. Mobile applications are presently at the primacy of documenting historical and archaeological sites. The current paper examine the methodological framework adopted for one high copy of Pharaonic artifacts, namely Offering Carrier, using hand held laser scanning and convert the results to a mobile application.

<p>The Moon Village Association (MVA) is a global organization that aims to foster collaboration between nations, space agencies, industry and the public, in order to facilitate the creation of a Lunar Economy. Despite its name, the purpose of the organization is not to create a base on the Moon. The "Moon Village" is the collection of people and organizations here on Earth that will collectively set Lunar activities in motion.</p> <p>The MVA's pilot mission - sending a Camera to the Lunar Surface to capture images of the earth and recreate the “Overview Effect” - aims to test in action how combining the capabilities of the MVA’s individual and institutional members can lower the entry barrier to the Lunar economy.</p> <p>The technical objective of the mission is to capture and live-stream a video of the Earth for 1 Lunar Day. The data will be broadcasted and utilized to engage the scientific community and general public to maximize mission returns for this and future missions.</p> <p>The challenge:</p> <p>Compared to Earth orbit missions, lunar missions are less prevalent, more technically complex with extra risks and completely different investment scales and timelines. This means that non-institutional space players have fewer opportunities to participate in lunar science and the creation of the Lunar Economy. There is also a lot of untapped capacity in the non-space world: Drawing a parallel to GIS, Sat Comms, Navigation etc., and progress achieved due to publicly accessible space-asset data in non-space industries, the potential benefit of opening up Lunar exploration to more players seems self-evident. The challenge is, however, enabling this global potential.</p> <p> Our talk will address this issue and will be structured to cover the following points:</p> <p>Mission description: We will describe our goals, why we decided to put a camera on the Moon, what are the technical requirements and why we selected the “Overview Effect” as our main objective.</p> <p>MVA Collaboration framework outline: This will address how we combine our varied strengths within the MVA to create a mission and how we want to see our members putting missions together in the future, on their own initiative. </p> <p>The MVA role, the role of volunteers and institutional partners: We will present how the building blocks fit together, what each side offers and receives through this collaboration.</p> <p>Lessons learned from the pre-phase A and phase A of the mission: We will discuss technical, financial, managerial, outreach and public engagement aspects, method-of-working issues, what were the biggest challenges to milestone success and how they were overcome.</p> <p>Obstacles and challenges moving forward: We will address our cost and schedule elements, paths to funding and risk management, and also ethics and responsible culture setting.</p> <p>How can someone get involved: As we are looking to engage both the scientific community and the public, we will be presenting information on where one can stay updated with our work, and what are the options for participation, either as an individual, an institution or a company.</p> <p>The talk will be designed and delivered from First Payload Project team members. The team is made up of both space and non-space industry professionals, all volunteers distributed across multiple time zones, without common working hours and a high chance of most members never meeting in person. The team is supported by the MVA’s institutional members (agencies, educational institutions and industry) in the form of in-kind contributions: an exchange of services, knowledge or materials given by the institutional member due to synergies between the mission objectives and the member’s own scientific or business objectives.</p> <p>This presentation will not focus on technical or scientific objectives or results of the 1st MVA Payload Project but on the process that is being created as a rubric for future lunar projects. From planning to set-up and further, and with the understanding that this is an ongoing process, this talk will present a guide of sorts or in the very least a detailed example of the processes necessary for private-sector lunar missions that deviate from the normal client-supplier models of institutional and Earth orbit missions.</p>

We propose a complete methodology for the fine registration and referencing of kilo-station networks of terrestrial laser scanner data currently used for many valuable purposes such as 3D as-built reconstruction of Building Information Models (BIM) or industrial asbuilt mock-ups. This comprehensive target-based process aims to achieve the global tolerance below a few centimetres across a 3D network including more than 1,000 laser stations spread over 10 floors. This procedure is particularly valuable for 3D networks of indoor congested environments. In situ, the use of terrestrial laser scanners, the layout of the targets and the set-up of a topographic control network should comply with the expert methods specific to surveyors. Using parametric and reduced Gauss-Helmert models, the network is expressed as a set of functional constraints with a related stochastic model. During the post-processing phase inspired by geodesy methods, a robust cost function is minimised. At the scale of such a data set, the complexity of the 3D network is beyond comprehension. The surveyor, even an expert, must be supported, in his analysis, by digital and visual indicators. In addition to the standard indicators used for the adjustment methods, including Baarda’s reliability, we introduce spectral analysis tools of graph theory for identifying different types of errors or a lack of robustness of the system as well as <i>in fine</i> documenting the quality of the registration.

An increasing number of hand-held scanning systems by different manufacturers are becoming available on the market. However, their geometrical performance is little-known to many users. Therefore the Laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has carried out geometrical accuracy tests with the following systems in co-operation with the Bochum University of Applied Sciences (Laboratory for Photogrammetry) as well as the Humboldt University in Berlin (Institute for Computer Science): DOTProduct DPI-7, Artec Spider, Mantis Vision F5 SR, Kinect v1 + v2, Structure Sensor and Google’s Project Tango. In the framework of these comparative investigations geometrically stable reference bodies were used. The appropriate reference data were acquired by measurement with two structured light projection systems (AICON smartSCAN and GOM ATOS I 2M). The comprehensive test results of the different test scenarios are presented and critically discussed in this contribution.
