This paper describes the results of an emergency recording and archiving of a historic structure in Southern Alberta and explores the lessons learned. Digital recording of the Quon Sang Lung Laundry building in Fort Macleod, Alberta, was a joint initiative between Alberta Culture and Tourism and the University of Calgary. The Quon Sang Lung Laundry was a boomtown-style wood structure situated in the Fort Macleod Provincial Historic Area, Alberta. Built in the mid-1800s, the structure was one of the four buildings comprising Fort Macleod’s Chinatown. Its association with Chinese immigration, settlement, and emergence of Chinese-owned businesses in early twentieth-century Alberta, made the Quon Sang Lung Laundry a unique and very significant historic resource. In recent years, a condition assessment of the structure indicated that the building was not safe and that the extent of the instability could lead to a sudden collapse. In response, Alberta Culture and Tourism engaged the Departments of Anthropology and Archaeology and Geomatics Engineering from the University of Calgary, to digitally preserve the laundry building. A complete survey including the laser scanning of all the remaining elements of the original structure, was undertaken. Through digital modeling, the work guarantees that a three-dimensional representation of the building is available for future use. This includes accurate 3D renders of the exterior and interior spaces and a collection of architectural drawings comprising floor plans, sections, and elevations.

This article reviews how reverse engineering is used in detecting and preserving. Engineers across many disciplines find reverse engineering an invaluable tool to discover and learn about a product’s structure and design. A good forensic engineer will glean relevant information through meticulous investigation and by taking a reverse-engineering approach. Texas Tech University, the National Park Service, and the Historic American Buildings Survey are now creating digital architectural drawings to detail the 120-year-old statue’s every curve, cranny, and dimension. They are doing this through reverse engineering. The university is capturing the statue's unique architecture with three-dimensional laser scanning technology tied to geometry processing software, which automatically generates an accurate digital model from the scan data. To help align the scans and to fix the holes, the team turned to technology that creates surface models from scanned data. The software is Geomagic Studio, from Raindrop Geomagic of Research Triangle Park, NC.

Photogrammetric Measurement

In the documentation of cultural heritage, we can encounter three dimensional shapes and structures which are complicated to measure. Such objects are for example spiral staircases, timber roof trusses, historical furniture or folk costume where it is nearly impossible to effectively use the traditional surveying or the terrestrial laser scanning due to the shape of the object, its dimensions and the crowded environment. The actual methods of digital photogrammetry can be very helpful in such cases with the emphasis on the automated processing of the extensive image data. The created high resolution 3D models and 2D orthophotos are very important for the documentation of architectural elements and they can serve as an ideal base for the vectorization and 2D drawing documentation. This contribution wants to describe the various usage of image based modelling in specific interior spaces and specific objects. The advantages and disadvantages of the photogrammetric measurement of such objects in comparison to other surveying methods are reviewed.

The Impact

Open educational resources (OER) have become increasingly popular in recent times. Here, the aim was to synthesise the lessons learned through the development of OER materials for a university-level course called “environmental modelling”. Consequently, the topics of discussion included: (i) how to choose an appropriate creative commons license; (ii) ways of incorporating materials from other sources, such as publicly available sources, other open access materials, and an author’s own published materials if not published under a creative commons license; (iii) the impact of the developed OER in the field of environmental modelling; and (iv) the challenges in developing OER material. Upon developing the materials, we observed the following: (i) students enrolled in the course did not purchase textbooks; (ii) our OER materials ranked as one of the most accessed (i.e., number 7) materials according to the usage data that summed the number of file downloads and item views from PRISM (i.e., the hosting platform maintained by the University of Calgary); (iii) the students learned relatively better as per the data acquired by the University of Calgary’s universal student ratings of instruction (USRI) instrument; and (iv) other universities expressed interest in adopting the materials.

The design of the Human Resource Management Certificate at the University of Calgary was the culmination of a two-year review process. Although the issue of declining enrolment initiated the review, many other issues became apparent. The process of informal and formal investigations that were undertaken are outlined, as are the actions taken. The challenges of resource constraints, collaborative investigation, the climate of competition in post-secondary institutions, and issues of credit transferability are highlighted along with the lessons learned. The process and results may benefit other continuing education programmers.

As immigration to Canada increases, so, too, do the complexities associated with serving various groups of newcomers, including immigrants, refugees, temporary foreign workers and international students. A range of stakeholder groups, such as grassroots community organisations, immigrant service provider organisations and academic researchers, have developed knowledge about how to best serve newcomers as they integrate into life in Canada. To date, there have been few opportunities for members of these and other stakeholder groups to work together to ensure that the needs of newcomers are being efficiently met. In this article, we describe a multi-step process of reciprocal knowledge engagement involving diverse stakeholders and led by the Newcomer Research Network at the University of Calgary. This engagement has the ultimate goal of developing a knowledge mobilisation hub focused on building capacity in community-engaged research with newcomers. In order to understand how we will reach this goal, this article outlines the efforts, priorities, challenges and important lessons learned that occurred as part of the multi-step process undertaken to establish a knowledge exchange with newcomer communities at its core.

Abstract Laser scanning in cadastral activities is a tool for obtaining information about real estate objects in a 3D format. The purpose of the research is to obtain information that is necessary for state cadastral registration and state registration of rights, land supervision and local government oversight. Deductive, inductive, analytical, comparative-legal and other scientific methods were used for the most complete coverage of the problem. The article considers the procedure of laser scanning, shooting modes when using laser scanning and the process of a real estate object 3D model creation. The methods of scanning were studied, namely: terrestrial, airborne and mobile. The greatest attention is paid to the advantages and features of using laser scanning technologies for real property. The results of the study showed that the laser scanner can be used not only in geodesy for engineering surveys, 3D modeling of quarries, when obtaining data on the volume of rock, during mining, assessing the situation in an emergency, but it can also be used in cadastral and complex cadastral works. The main attribute of laser scanning is a three-dimensional representation of data about the object, which can be immediately used, but the high accuracy and low labor costs are no less important. Therefore, three-dimensional laser scanning technologies can be used both in the creation of models of cities, and the unified cartographic basis of the Unified State Register of Real Estate, as well as in valuation activities during the taxation of buildings and structures.

The Great Orbital Run was a solitary run/artwork that took place over nine days around the inside boundary of the M25 London Orbital. The journey was mapped through a stream of photographs and GPS coordinates relayed live from a mobile phone to a web interface and shown as a projected artwork at the University of Greenwich, London. It was later re-configured as the M25 in 4000 images, a unique concertina bookwork/sculpture produced from digital data into tangible, printed paper form. Cut, folded, and constructed by hand, it makes visible the mass of images that embody the running activity and the terrain it represents. This essay considers this artwork and its status as a document and artist’s book, reflecting on (1) the original running activity, (2) the mapping of the boundary of Greater London, (3) the performance of technology in relaying the run, and (4) the transformation of digital images into material form. The document is considered in relation to the run as a performance and in relation to its performative potential. This is extended to the documentary properties of the artists’ book as ‘a form of three-dimensional representation’ that, through its ‘agency’, aligns itself with spatial practice.

    A three-dimensional (3D) model extraction represents the best way to reflect the reality in all details. This explains the trends and tendency of many scientific disciplines towards making measurements, calculations and monitoring in various fields using such model. Although there are many ways to produce the 3D model like as images, integration techniques, and laser scanning, however, the quality of their products is not the same in terms of accuracy and detail. This article aims to assess the 3D point clouds model accuracy results from close range images and laser scan data based on Agi soft photoscan and cloud compare software to determine the compatibility of both datasets for several applications. College of Science, Departments of Mathematics and Computer in the University of Baghdad campus were exploited to create the proposed 3D model as this area location, which is one of the distinctive features of the university, allows making measurements freely from all sides. Results of this study supported by statistical analysis including 2 sample T-test and RMSE calculation in addition to visual comparison. Through this research, we note that the laser3D model provides many points in a short time, so it will reduce the field work and also its data is faster in processing to produce a reliable model of the scanned area compared with data derived from photogrammetry, then the difference were computed for all the reference points.

Curved Panels

Constructing free-form buildings is very complex due to the difficulty in fabricating the curved façade. To install the façade, the complex geometric shapes of the façade need to be divided into panels. The panels developed are classified into three categories in terms of their curvatures, i.e., planar, single-curved, double-curved panels. The quality of the curved façade is determined by the geometric difference between as-built and as-designed panel shapes. Among the three types of curved panels, the double-curved panel is very difficult to form, showing greater quality discrepancy than the other two panel types. Ensuring the as-built quality of the curved façade is for contractors. The main objective of this study is to enhance small/mid-size contractors’ capacity of managing the as-built quality of the double-curved panel. To meet the study objectives, a case study of a small free-form building and empirical mock-up tests of curved panels were performed and beneficial lessons for the contractors were identified through the tests. Among diverse materials, aluminum and glass-fiber-reinforced concrete (GFRC) were utilized for the mock-up tests. Three-dimensional laser scanning technology was employed to foster the as-built data of the case study project and the mocked-up double-curved panels. The data superimposition method was used to measure the deviation between the as-designed and the as-built data of the case study.
