ANALISIS AKURASI PEMETAAN MENGGUNAKAN DIRECT GEOREFERENCING

GEOMATIKA, 2018
Banyak tantangan yang harus dihadapi ketika melaksanakan survei <br />Ground Control Point (GCP). Salah satu upaya meminimalisir jumlah titik kontrol adalah melakukan pengukuran posisi dan orientasi foto udara tanpa GCP, atau disebut direct georeferencing .

Memory-Efficient Georeferencing of Segmented Satellite Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Accurate georeferencing is essential for the prompt and rapid use of Earth Observation data. Direct georeferencing algorithms, using satellite orbital position and attitude to compute geolocation pixels, are commonly used.

HIGH-PRECISION POSITIONING AND REAL-TIME DATA PROCESSING OF UAV-SYSTEMS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Available micro-sized Unmanned Aerial Vehicles (UAVs) in the civilian domain currently make use of common GPS receivers and do not address scenarios where high-precision positioning of the UAV is an inevitable requirement.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Real Time Airborne Monitoring for Disaster and Traffic Applications [PDF]

, 2011
Remote sensing applications like disaster or mass event monitoring need the acquired data and extracted information within a very short time span. Airborne sensors can acquire the data quickly and on-board processing combined with data downlink is the ...

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Species with U‐shaped geographic ranges as an opportunity to study early stages of divergence: The case of Ipomoea microsepala

American Journal of Botany, EarlyView.
Abstract Premise The study of the early stages of divergence between populations is crucial to understanding how species and biodiversity originate. Geographic distributions that capture some aspects of the process of divergence, such as those that are markedly U‐shaped, could offer a window to identify systems undergoing incipient speciation, which ...

Evaluation of the Accuracy of Photogrammetric Reconstruction of Bathymetry Using Differential GNSS Synchronized with an Underwater Camera [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Photogrammetry is a valuable tool for 3D documentation, mapping, and monitoring of underwater environments. However, the ground control surveys necessary for georeferencing and validation of the reconstructed bathymetry are difficult and time consuming ...
