Three-Dimensional Unique-Identifier-Based Automated Georeferencing and Coregistration of Point Clouds in Underground Mines [PDF]
Remote Sensing. 2021; 13(16):3145, 2021 Spatially and geometrically accurate laser scans are essential in modelling infrastructure for applications in civil, mining and transportation. Monitoring of underground or indoor environments such as mines or tunnels is challenging due to unavailability of a sensor positioning framework, complicated structurally symmetric layouts, repetitive features

Direct Georeferencing of Stationary LiDAR [PDF]
Remote Sensing, 2009 Unlike mobile survey systems, stationary survey systems are given very little direct georeferencing attention. Direct Georeferencing is currently being used in several mobile applications, especially in terrestrial and airborne LiDAR systems ...

Automatic content‐based georeferencing of historical topographic maps [PDF]
Trans. GIS, 2021 Old maps are more than a cultural artefact: they are data. Data about the past still hold value for science and decision‐making today. Libraries and archives have come a long way in digitising their inventories of thousands, sometimes millions, of ...

Automatic Georeferencing of Topographic Raster Maps
ISPRS International Journal of Geo-Information, 2022 In recent years, many scientific institutions have digitized their collections, which often include a large variety of topographic raster maps. These raster maps provide accurate (historical) geographical information but cannot be integrated directly ...
