Total stations: the surveyor's workhorse / Mathias Lemmens in GIM international, vol 30 n° 10 (October 2016)  

Public [article]  inGIM international > vol 30 n° 10 (October 2016) . - pp 20 - 26 Titre : Total stations: the surveyor's workhorse Type de document : Article/Communication Auteurs : Mathias Lemmens, Auteur Année de publication : 2016 Article en page(s) : pp 20 - 26 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Topographie moderne [Termes IGN] lever topographique [Termes IGN] tachéomètre électronique [Termes IGN] tachéomètre électronique robotisé [Termes IGN] vidéotachéomètre Résumé : (éditeur) A total station is an angle measuring device, also known as a theodolite, integrated with an electronic distance measurement (EDM) unit. The integration provides the ability to measure horizontal and vertical angles as well as slope distances using the same device at the same time, which benefits the surveyor in terms of portability, convenience and speed. Today, total stations have a wide variety of capabilities and are extensively exploited in cadastral surveying, civil engineering and on construction sites. The author provides a synopsis of features, status and trends.

GPS and the 2015 Gorkha Earthquake / Mathias Lemmens in GIM international, vol 29 n° 11 (November 2015)

Public [article]  inGIM international > vol 29 n° 11 (November 2015) . - pp 29 - 31 Titre : GPS and the 2015 Gorkha Earthquake Type de document : Article/Communication Auteurs : Mathias Lemmens, Auteur Année de publication : 2015 Article en page(s) : pp 29 - 31 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Navigation et positionnement [Termes IGN] déformation de la croute terrestre [Termes IGN] Himalaya [Termes IGN] positionnement par GPS [Termes IGN] réseau de surveillance géophysique [Termes IGN] réseau géodésique [Termes IGN] séisme Résumé : (auteur) Nepal is prone to earthquakes and throughout the centuries the country's capital city, Kathmandu, has been regularly struck by earthquakes which appear to have similar epicentres and behaviour. The portion of the Main Himalayan Thrust ruptured by the 2015 Gorkha earthquake lies directly beneath a network of GPS continuously operating reference stations (CORS) recording three-dimensional positions at a high rate of 5 samples per second (5Hz). This is the first time a large continental thrust earthquake has been measured by a 5Hz GPS network with receivers on both sides of the fault rupture.

GIM international: 25 years of development / Mathias Lemmens in GIM international, vol 26 n° 6 (June 2012)

Public [article]  inGIM international > vol 26 n° 6 (June 2012) . - pp 20 - 27 Titre : GIM international: 25 years of development Type de document : Article/Communication Auteurs : Mathias Lemmens, Auteur Année de publication : 2012 Article en page(s) : pp 20 - 27 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] cartographie [Termes IGN] évolution technologique [Termes IGN] géomatique [Termes IGN] métier [Termes IGN] système d'information géographique [Termes IGN] topographie Résumé : (Auteur) Twenty-five years ago, our profession was simply called ‘land surveying’, which meant accurately measuring points located on or near the Earth’s surface. These points represented objects such as buildings, roads, rivers or the bare ground, or delineated property boundaries. The process of storing and representing the information derived from the measurements was called mapping. Nowadays, we tend to be involved in sensing rather than surveying and modelling rather than mapping. To mark the occasion of the 25th anniversary of GIM International, the magazine’s former editor-in-chief has written this article looking back on a quarter of a century of developments in geodata acquisition.

Digital photogrammetric workstations / Mathias Lemmens in GIM international, vol 25 n° 12 (December 2011)  

Public [article]  inGIM international > vol 25 n° 12 (December 2011) . - pp 28 - 31 Titre : Digital photogrammetric workstations Type de document : Article/Communication Auteurs : Mathias Lemmens, Auteur Année de publication : 2011 Article en page(s) : pp 28 - 31 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Photogrammétrie numérique [Termes IGN] détection de contours [Termes IGN] extraction de traits caractéristiques [Termes IGN] station de travail de photogrammétrie numérique [Termes IGN] traitement automatique de données Résumé : (Auteur) For over a century, images taken from above-ground platforms have been major data sources for topographic mapping, creation of base maps and many other uses. For the past decade or more, data has been extracted from the imagery using computer software on what have become known as digital photogrammetric workstations. Some of the tasks can be performed almost fully automatically while others require extensive human involvement. To tie in with the new product survey on digital photogrammetric workstations published on our website, this article discusses the latest status and features.

Digital aerial cameras / Mathias Lemmens in GIM international, vol 25 n° 4 (April 2011)  

Public [article]  inGIM international > vol 25 n° 4 (April 2011) . - pp 35 - 41 Titre : Digital aerial cameras Type de document : Article/Communication Auteurs : Mathias Lemmens, Auteur Année de publication : 2011 Article en page(s) : pp 35 - 41 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Acquisition d'image(s) et de donnée(s) [Termes IGN] caméra numérique [Termes IGN] chambre à grand format [Termes IGN] chambre à moyen format [Termes IGN] instrument aéroporté Résumé : (Auteur) The growing need for geo-data everywhere is driving customers to demand shorter turnaround rates and higher levels of detail. These needs can be met by aerial imagery directly captured in digital format onboard an aircraft. In tandem with the new product survey on Digital Aerial Cameras (see our website), the author here gives an overview of new developments.
