THE ASSESSMENT OF ORTHOPHOTO QUALITY WITH RESPECT TO THE STRUCTURE OF DIGITAL ELEVATION MODEL [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Abstract. Orthophoto is an image which is being corrected geometrically so each object has to be situated on the corrected place consequently. Choosing the best DEM structure with respect to the area topographic is the most challenge which has more important role when dealing with rough surfaces displacements in duration of orthophoto procedures.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Comparision of Spatial Accuracy and Cost in Digital Orthophoto Maps

Selçuk Üniversitesi Mühendislik, Bilim ve Teknoloji Dergisi, 2005
Coğrafi Bilgi Sistemi (CBS) çalışmalarında; konumsal verilerin elde edilmesi büyük önemesahiptir. CBS projelerinin başarıya ulaşması, elde edilen konumsal verilerin, oluşturulan CBS projesiningerektirdiği doğrulukta ve güncellikte olmasına bağlıdır. Bu, sınırlı olan ülke kaynaklarının israfedilmemesi açısından önemlidir.

A literature‐based framework for anticipating golden jackal Canis aureus colonisation: insights from Europe and a Swiss case study

Wildlife Biology, EarlyView.
The expansion of the golden jackal Canis aureus in Europe, caused mainly by habitat fragmentation, climate change and the decline of large carnivores until half a century ago, poses emerging challenges for newly colonised regions. With the arrival of a new species, potential effects on local animal communities, hunting, livestock husbandry or the ...

EXTRACTION OF BUILDING ROOF EDGES FROM LIDAR DATA TO OPTIMIZE THE DIGITAL SURFACE MODEL FOR TRUE ORTHOPHOTO GENERATION

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
. Various kinds of urban applications require true orthophotos. True orthophoto generation requires a DSM (Digital Surface Model) to project the photo orthogonally and minimize geometric distortion due to topographic variance.

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.
