Advances in technology have promoted changes several areas, topography this panorama wasn't different, promoting efficiency and digitalization of processes. The recently deployed the is use Remotely Piloted Aircraft conjunction with Global Navigation Satellite System to perform aerophotogrammetric surveys, but still has limitations its accuracy when compared traditional methods. Supporting tech...

The paper presents the project which was carried out in the Photogrammetric Laboratory of Warsaw University of Technology. The experiment is concerned with the extraction of 3D vector data for buildings creation from 3D photogrammetric model based on the Ikonos stereo images. The model was reconstructed with photogrammetric workstation Summit Evolution combined with ArcGIS 3D platform. Accuracy...

We present the Distributed Simplex Architecture (DSA), a new runtime assurance technique that provides safety guarantees for multi-agent systems (MASs). DSA is inspired by control architecture of Sha et al., but with some significant differences. The traditional approach limited to single-agent or MAS centralized scheme. addresses this limitation extending scope include MASs under distributed c...

epizoochory and endozoochory are well-known mechanisms by which seeds are dispersed by animals. since, livestock gather around the watering-points to rest and drink, we expected to find that seeds would be frequently moved to the areas surrounding watering-points, resulting a higher soil seed density (and diversity) closest to the water. we investigated this issue by assessing soil seed bank de...

Measurement of the geometry marine-terminating glaciers is challenging due to lack stable ground areas in close proximity glacier. This precludes use fixed measuring devices and restricts placement control points. We propose a measurement procedure for using structure-from-motion including proper survey planning, point design model alignment. As case study, we surveyed Hans Glacier, Hornsund fj...

This TR discusses aspects of using ground control to validate the computational terrain reconstruction. Image features provided for stereo matching allow to deduce simple confidence measures for reconstructed terrains, and only sufficiently confident terrain points should be validated by the available control data. 1 CITR, Tamaki Campus, University Of Auckland, Auckland, New Zealand Con dence o...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

Since GPS technology which is intensively used in surveying application today, can not directly be employed to measure some details such as building boundaries, it is still a necessity to establish control points on the ground and coordinate them by GPS and then measure the details by a total station set up on these control points. Establishment of control points on the ground and their compuls...

Parametric geocoding is a standard procedure for orthorectification of hyperspectral airborne scanner data. Boresight parameters are estimated by using the image coordinates of precisely known ground reference points. To fully automate the processing of the recorded hyperspectral data ground reference points should be selected and matched by an algorithm without user interaction. In this articl...
