Unmanned Aircraft Systems (UASs) can collect high resolution and high quality images for local mapping. If the highly accurate GPS flying trajectory of a UAS is collected, it can support bundle adjustment aerial triangulation (AT) of UAS images and reduce... see more

Abstract: Geospatial data (on horizontal and vertical positions) play an important role in decision making.Regarding that, the issue of funds, diversity of areas, human resources, and non-updated data become great obstacles. This study aims to examine the... see more

The bathymetry on and around an ebb-tidal delta at a natural headland and barrier-bound inlet on the Bay of Plenty coast, New Zealand, was surveyed using a modern, integrated echo-sounding and navigation system. The survey aims were to define the morpholo... see more

Traditional field-based techniques for phenotyping of crops are based on visual assessment which are subjective and time consuming. A high throughput automated technique using an unmanned aerial vehicle (UAV) with a multispectral image (MSI) camera was us... see more

Small Scale Mapping Sector uses UAV (Unmanned Aerial Vehicle) as a mapping tool. UAVs require wireless and long-distance communication. For this reason, an antenna with a far beam pattern and a high gain are needed. This research uses the Yagi Antenna bec... see more

This research focuses on the load and stability of unmanned aerial vehicles that are as light as possible but with optimal stability functions and increasing the capacity of liquid fertilizer lifted by unmanned aerial vehicles. The increase in lift is rel... see more

Discovery Unmanned Aerial Systems/UAS is used in various fields such as reconnaissance tools, topological mapping, and recreational purposes. This must be balanced with legal arrangements because there are many misuses of UAS operations. Act No. 1 of 2019... see more

Let G be a connected graph. If s(v) denotes the arithmetic mean of the distances from v to all other vertices of G, then the proximity, p(G), of G is defined as the smallest value of s(v) over al... see more

This study aimed at reporting the contexts of interest in needs analysis research (NAR) in the Arab World (2000 – 2019) and describing the adoption of triangulation in data collection instruments and data sources. A purposive sample of 48 published NAR wa... see more
