This paper presents an approach for generating 3D panoramic map - historical reconstruction of Izgrev district in Sofia, Bulgaria for the period 1927-1944. The main advantage of 3D maps is the clear and realistic visualization of the mapped objects and the environment. The present study aims to generate a three-dimensional panoramic map - historica...

The development of 3D models in GIS environment is particularly relevant for open-pit mining and follow-up activities in opencast mines. In this study two methods for 3D modeling are presented for the needs of the reclamation of an old stone quarry in the village of Potoka, Gabrovo municipality on the territory of the Natural Park "Bulgarka". Tradi...

Mapping and three-dimensional modeling of mountain areas, together with the study of land cover change dynamics, is a topical task for the protection and maintenance of protected natural parks and forests. Unmanned aerial systems (systems) are an established successful alternative for collecting remotely sensed Earth observation data with a wide ra...

The mapping and three-dimensional modeling of mountain areas and the study of land cover change dynamics are current tasks in preserving and maintaining protected natural parks and forests. In this context, recent developments in digital photogrammetry using the SfM-MVS method to process captured imagery and the development of unmanned aerial syste...

In recent years, unmanned aerial vehicles (UAVs) have increased rapidly and successfully established themselves as a tool for the rapid collection of high-resolution images as baseline data in land cover studies and topographic mapping. In photogrammetry using the SfM-MVS method of processing captured images, indirect georeferencing of the digital...

Terrestrial surveying and mapping of hard-to-reach or inaccessible areas are challenging tasks. In addition to classical geodetic methods, remotely piloted aircraft systems (RPAS), also known as uncrewed aerial vehicles (UAVs), can be used as an alternative method to solve similar research and application problems. In the last two decades, GNSS and...

The use of unmanned aerial vehicle systems (UAVs) for the acquisition of images, which are then processed by the photogrammetric method SfM (Structure-from-motion), is increasingly established as a suitable workflow for obtaining high-resolution topographic data (HRTD). Using PPK (Post-Processed Kinematic) solutions for UAVs can provide accurat...

Unmanned aerial systems (UAS) are a dynamically developing sector in remote sensing and are increasingly used for photogrammetric capturing and mapping of the earth's surface. In this research, under “Open Source UAS” with is understood the combination of software and hardware required for the construction and management of open-source unmanned aer...

The cartography does not stop its progress-it becomes more attractive, more innovative and more applicable in different fields of life. Using 3D and interactive maps is almost daily routine. There are big amounts of all kind of geospatial data and almost every place in the world is mapped. But what about if a map of a place that does not exist anym...

The use of unmanned aerial systems (UAS) for image acquisition, which are then processed by the photogrammetric method SfM-(Structure-from-motion), is increasingly established as a suitable workflow for obtaining high-resolution topographic data (HRTD). During the last few years the development of high-quality IMU (Inertial Measurement Unit) and GN...

In recent years, the unmanned aerial vehicle systems (UAVs) have demonstrated significant potentialities with potential for applications in many fields. Mapping of inaccessible and dangerous territories through field study methods is a challenging task. Remote sensing techniques may provide an alternative solution to such tasks. Usually single GNSS...

Използването на безпилотни летателни системи (БЛС) за заснемане на културно-исторически паметници позволява получаването на актуални и качествени изображения. Технологията е подходяща за заснемане на отделни монументи или комплекси от сгради и съоръжения. За да се демонстрира прецизността и надеждността на процедурата, в статията е разгледан пример...

Capturing, documentation and visualization of natural heritage objects is an expanding application area. Advanced Unmanned Aerial Systems (UAS) offer a technology of obtaining geometrical and semantic information about natural landmarks from imaging using various types of sensors. The use of non-metric digital cameras embedded in middle-class UAS t...

Основната цел на изследването е разработване и прилагане на систематизиран подход за създаване на високоточен цифров 3D модел на Природен парк „Врачански Балкан“ за триизмерно картографиране и интегриране в система за мониторинг, както и разкриване приложимостта на дистанционните методи чрез използване на безпилотни летателни системи за 3D моделира...

Recently, accurate three-dimensional (3D) data and mapping applications have become advanced prerequisites for supporting the development and management of tourism. The derived high quality mapping products allow both natural and manmade features to be captured in great detail. The main advantage of 3D maps is the clear and realistic visualization...

Building three-dimensional (3D) models and photorealistic visualizations of environment is important in many applications ranging from virtual representation of landscape to analysis and monitoring of land cover/use, as well as landscape management and planning. The aim of 3D modelling of landscape is to produce according to the user needs sufficie...
