In land surveying the exact position and shape of objects on the surface of the earth is mapped. Included in the position is the height of an object. Techniques used are for example the total station, level instrument and GNSS. There is a direct relation between modern Remote Sensing techniques and land surveying and topography and often they are used side by side with land survey techniques providing highly accurate coordinates and remote sensing providing a broader overview. In traditional land surveying and topography objects are located in x,y and z with the addition of an object type. However, nowadays more and more attribute information is collected as well allowing detailed databases and products to be developed in cartography.
An important application for land surveying and topography is in construction and engineering but also in for example land and water management. Where land surveying and topography is about the visible objects on the earth surface, marine surveying and bathymetry is concerned with the objects under the water surface.
The use of 3D laser scanners is expanding the role of geospatial technology in criminal investigations. The technology is being used to produce accurate, feature-rich visualizations of crime scenes th...
Terrestrial laser scanning enables the acquisition of massive amounts of geo-referenced spatial data in a fraction of the time required by traditional methods. The remote scanning positions also impro...
What is the current status of surveying in the mining industry, and which types of survey equipment and technologies are being used today? Geospatial data forms the foundation of mining. The rapidly e...
3D mapping of roads, pipelines and other linear structures – often called corridors – is an important geomatics activity. Geodata acquisition technologies, which are increasingly used for corridor...
Spatial information is essential for sustainable development. In developing countries land management is often hindered by the absence of national spatial-information policy, guidelines for metadata m...
Photogrammetry was already in existence more than a century ago, although, judging by current standards, only in its infancy. This technology, gradually refined over time and now ripened into maturit...
In the early days of surveying, surveyors were pioneers in charting the unknown. Today, with the Earth having been completely mapped to some degree, surveying has become a much more specialized field ...
Less than six months into her term of office, 'GIM International' spoke to Diane Dumashie, president of FIG (2023-2026), to hear about her experiences so far. Here, she shares her perspectives on a ke...
In this exclusive interview, two of the driving forces behind this year's Intergeo talk about the event's evolution and impact, nurturing talent, land surveying, Earth observation and the Blue Economy...
When conducting surveys in countries near the equator, environmental conditions can be harsh. Heat, dust and humidity may disrupt sensitive equipment, while distrustful locals may obstruct the underta...
Traditional techniques for developing land administration include high-accuracy field-based surveying of the property boundaries by certified surveyors, and may still be a desired solution for cadastr...
How is it possible that so many poor, vulnerable people and small farmers are the ones to suffer when their land is grabbed by the state, large investors or local elites? Doesn’t the Universal Decla...
Mount Elbrus, with its peak of 5,642m, is the highest mountain in Europe. This makes it a remarkable attraction for adventurers, hikers and skiers from around the world, which calls for safe and perma...
We asked James Kavanagh, head of land & resources with The Royal Institution of Chartered Surveyors (RICS), about the challenges facing the geospatial industry, the technological developments that wil...
