Validation of Regional Positioning Service User Connections as Support in Update Cartography

Transactions in GIS, Volume 29, Issue 1, February 2025.
ABSTRACT The significant demand for highly updated geospatial or cartographic information surpasses the capacity of the official agencies responsible for its generation. The procedure for updating official cartography, in some Spanish regions, can take more than three or 4 years.

A Novel Approach for Autonomous Densely Spaced Acquisition of Buried Objects in Intertidal Environments—Field Examples From Avaldsnes, Norway

Archaeological Prospection, Volume 32, Issue 1, Page 59-76, January/March 2025.
ABSTRACT Underwater archaeology relies on expensive and time‐consuming invasive methods for identifying and excavating objects buried in the seabed or identifying layers in shallow and intertidal environments. Especially shallow and intertidal environments are challenging due to locally high levels of sedimentation that offer good conditions for ...

Spatial Distribution of Thaw Depth in Palsas Estimated From Optical Unoccupied Aerial Systems Data

Permafrost and Periglacial Processes, Volume 36, Issue 1, Page 22-36, January/March 2025.
ABSTRACT Maximum seasonal thaw depth, referred to as active layer thickness (ALT), is one of the key parameters used to monitor permafrost conditions. ALT maps based on interpolation of point measurements or derived from coarse or moderate spatial resolution satellite data often hide small‐scale spatial variations in thaw depth resulting from ...

Initial Results of RTK/OTF Positioning Using the Ntrip Data Teletransmission Technology

Technical Sciences, 2008
The paper presents the initial results of RTK/OTF satellite measurements made using NTRIP Internet data transmission. Two permanent reference stations belonging to the University of Warmia and Mazury in Olsztyn were used for test measurements. As a result of measurements taken at three measurement points situated 1,5 to 20 kilometers from the reference
