GEOREFERENCING IN IFC: MEETING THE REQUIREMENTS OF INFRASTRUCTURE AND BUILDING INDUSTRIES

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
. The problem of georeferencing building information modelling (BIM) models is complex and in need of a comprehensive solution. We focus on the open BIM data format Industry Foundation Classes (IFC) and its georeferencing implementation. The requirements

The road to success and the fences to be crossed: considering multiple infrastructure in landscape connectivity modelling

Wildlife Biology, EarlyView., 2023
Linear infrastructure represent a barrier to movement for many species, reducing the connectivity of the landscapes in which they reside. Of all linear infrastructure, roads and fences are two of the most ubiquitous, and are understood to reduce landscape connectivity for wildlife.

EVALUATION OF SAR DATA AS SOURCE OF GROUND CONTROL INFORMATION: FIRST RESULTS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
The high resolution imaging modes of modern SAR sensors has made SAR data compatible with optical images. SAR data offers various capabilities which can enhance the geometric correction process of optical images (accurate, direct and ground-independent

GNSS-denied geolocalization of UAVs by visual matching of onboard camera images with orthophotos [PDF]

2021 20th International Conference on Advanced Robotics (ICAR), Dec. 2021, pp. 555-562, 2021
Localization of low-cost Unmanned Aerial Vehicles (UAVs) often relies on Global Navigation Satellite Systems (GNSS). GNSS are susceptible to both natural disruptions to radio signal and intentional jamming and spoofing by an adversary. A typical way to provide georeferenced localization without GNSS for small UAVs is to have a downward-facing camera ...

Deflection of Vertical Effect on Direct Georeferencing in Aerial Mobile Mapping Systems: A Case Study in Sweden

Photogrammetric Record, 2022
GNSS/INS applications are being developed, especially for direct georeferencing in airborne photogrammetry. Achieving accurately georeferenced products from the integration of GNSS and INS requires removing systematic errors in the mobile mapping systems.

An evaluation of detection methods for the plains spotted skunk

Wildlife Society Bulletin, Volume 46, Issue 5, December 2022., 2022
The conservation status of the plains spotted skunk is currently poorly understood in Texas. We collected occurrence data by multiple methods (field survey, crowdsourcing, and citizen scientist led camera trap surveys), analyzed the detection rates of survey devices (camera traps, live traps, and track plates), and the relative efficacy of citizen ...

Georeferencing for Research Use (GRU): An integrated geospatial training paradigm for biocollections researchers and data providers [PDF]

Research Ideas and Outcomes, 2018
Georeferencing is the process of aligning a text description of a geographic location with a spatial location based on a geographic coordinate system. Training aids are commonly created around the georeferencing process to disseminate community standards

Regional‐Scale Landscape Response to an Extreme Precipitation Event From Repeat Lidar and Object‐Based Image Analysis

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract Extreme precipitation events may cause flooding, slope failure, erosion, deposition, and damage to infrastructure over a regional scale, but the impacts of these events are often difficult to fully characterize. Regional‐scale landscape change occurred during an extreme rain event in June 2012 in northeastern Minnesota.

Achieving Brazil's Deforestation Target Will Reduce Fire and Deliver Air Quality and Public Health Benefits

Earth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract Climate, deforestation, and forest fires are closely coupled in the Amazon, but models of fire that include these interactions are lacking. We trained machine learning models on temperature, rainfall, deforestation, land‐use, and fire data to show that spatial and temporal patterns of fire in the Amazon are strongly modified by deforestation ...
