Recently, the growing role laser scanning application UAVs has also been observed. Laser scanners dedicated consist four basic components: scanner (LiDAR), an Inertial Measurement Unit (IMU), Global Navigation Satellite System (GNSS) receiver on-board computer. The producers system...

Abstract A total of 2848 denarii from the Nietulisko Małe Hoard, one largest hoards Roman coins found in Poland, were digitised and documented using reflectance transformation imaging, highlighting potential for this technology numismatic research.

Abstract. During the last decade use of airborne multi camera systems increased significantly. The development in digital technology allows mounting several mid- or small-format cameras efficiently onto one platform and thus enables image capture under different angles. Those oblique images turn out to be interesting for a number applications since lateral parts elevated objects, like buildings trees, are visible. However, occlusion illumination differences might challenge processing. From...

This research is related to the exploitation of multispectral imagery from an unmanned aerial vehicle (UAV) in assessment damage rapeseed after winter. Such one a few cases for which reimbursement may be claimed agricultural insurance. Since direct measurements are difficult such case, mainly because large, unreachable areas, it therefore important able use remote sensing plant surface affected by frost damage. In this experiment, UAV images were taken using Sequoia camera that collected...

This article presents the preliminary results of possibilities for using an unmanned aerial system (UAS) three-dimensional (3D) data collection levees. The UAS is equipped with ultra-light laser scanner and digital camera that acquires stereoscopic coverage. Sensors have been mounted on multi-rotor. Using such a platform allows obtaining 3D necessary circular surveying works regard to levee monitoring prevention flooding. Such can offer alternative typical direct measurements performed...

Abstract. This paper presents the possibilities for using an unmanned aerial system evaluation of condition levees. The is equipped with two types sensor. One ultra-light laser scanner, integrated a GNSS receiver and INS system; other sensor digital camera that acquires data stereoscopic coverage. Sensors have been mounted on multirotor, platform Hawk Moth, constructed by MSP company. LiDAR images levees length several hundred metres were acquired during testing platform. Flights performed...

In the last decade, many aerial photographic archives have started to be digitized for multiple purposes, including digital preservation and geoprocessing. This paper analyzes effects of professional photogrammetric versus consumer-grade scanners on processing analog historical photographs. An image block over Warsaw is considered, featuring 38 photographs acquired in 1986 (Wild RC10, Normal Aviogon II lens, 23 × cm format) with a ground sampling distance (GSD) 4 cm. Aerial triangulation...

Abstract. Updating the cadastre requires much work carried out by surveying companies in countries that have still not solved problem of updating cadastral data. In terms required precision, these works are among most accurate. This raises question: to what extent may modern digital photogrammetric methods be useful this process? The capabilities photogrammetry increased significantly after introduction aerial cameras and technologies. For registration objects, i.e., land parcels’ boundaries...

Abstract. Creating 3D building models in large scale is becoming more popular and finds many applications. Nowadays, a wide term “3D models” can be applied to several types of products: well-known CityGML solid (available on few Levels Detail), which are mainly generated from Airborne Laser Scanning (ALS) data, as well mesh that created both nadir oblique aerial images. City authorities national mapping agencies interested obtaining the models. Apart completeness models, accuracy aspect also...

This article presents a new approach to the estimation of shift and rotation between two images from different kinds imaging sensors. The first image is an orthophotomap that created using optical sensors with georeference information. second one utilizing Synthetic Aperture Radar (SAR) sensor.The proposed solution can be mounted on flying platform, and, during flight, obtained SAR are compared reference images, thus it possible calculate these then direct georeferencing error. Since both...

Abstract. Oblique aerial images have been a source of data for urban areas several years. However, the accuracy measurements in oblique during this time has limited to single meter due use direct -georeferencing technology and underlying digital elevation model. Therefore, used mostly visualization purposes. This situation changed recent years as new methods, which allowed higher exterior orientation, were developed. Current developments include process determining orientation previous but...

Abstract. Immersive technologies like Virtual or Augmented Reality (VR/AR) are lately becoming more and popular in wide range of scientific applications. These provide the most immersive way to present spatial data such as point clouds 3D models. This type solutions also has significant potential for virtual presentation cultural heritage. Combination high-quality photogrammetric models, reality an advanced visualization engine may bring effect form a nearly real-world experience which be...

The process of secondary succession is one the most significant threats to non-forest (natural and semi-natural open) Natura 2000 habitats in Poland; shrub tree encroachment taking place on abandoned, low productive agricultural areas, historically used as pastures or meadows, leads changes composition species biodiversity loss, results landscape transformations. There a perceived need create methodology for monitoring vegetation by airborne remote sensing, both from quantitative (area,...

This paper presents changes in the range and thickness of glaciers Antarctic Specially Protected Area (ASPA) No. 128 on King George Island period 1956–2015. The research indicates an intensification glacial retreat process over last two decades, with rate depending type glacier front. In 2001–2015, average recession ice cliffs Ecology Glacier northern part Baranowski was estimated to be approximately 15–25 m a−1 10–20 a−1, respectively. Fronts Sphinx southern Glacier, characterized by a...

Nea Paphos, the Hellenistic-Roman capital of Cyprus, was established according to a regular Hippodamian street grid in Hellenistic period. The city has been subjected continuous archaeological research since 1960s. Despite this, possibilities for reconstructing its fabric were severely limited. This paper aims gain more in-depth understanding ways which computational methods can be used analysis ancient urban planning and reconstruction elements, using similarity processes social behavior...

Data synergy involves acquiring and combining data from different sensors to achieve better problem analysis research results. For more comprehensive analysis, the are not only mounted on one platform. Still, they should also be compatible with software hardware, e.g. for same timestamp registration by sensors.
