The purpose of this study is to find the suitability seaweed cultivation land on Lembeh Island and its surroundings. data collection technique in was divided into several events, namely primary collection, where implementation carried out field such as conducting a ground check from results analysis. In addition, there are also secondary that generally come local government related study. study...

Moso bamboo (Phyllostachys heterocycla (Carr.) Mitford cv. Pubescens) is an important timber substitute in China. Site specific stand management requires an accurate estimate of soil organic carbon (SOC) stock for maintaining stand productivity and understanding global carbon cycling. This study compared ordinary kriging (OK) and inverse distance weighting (IDW) approaches to study the spatial ...

Aim Species distribution maps are essential for assessing extinction risk and guiding conservation efforts. However, most come sourced as expert-drawn range with known issues of accuracy or developed overly complex modelling procedures. Thus, data-driven alternatives that accessible reliable a welcome addition to the spatial toolkit. Here, we geospatial workflow refine species from its extent o...

Laser scanning via LiDAR is a powerful technique for collecting data necessary Digital Terrain Model (DTM) generation, even in densely forested areas. observations located at the ground level can be separated from initial point cloud and used as input generation of interpolation. This paper proposes quantitative analysis accuracy DTMs (and derived slope maps) obtained focused on conditions comm...

In order to estimate rainfall magnitude at unmeasured locations, this entry to the Spatial Interpolation Comparison of 1997 (SIC'97) used 2-dimensional, anisotropic, inverse-distance weighting interpolator (IDW), with cross-validation as a method of optimizing the interpolator's parameters. A jackknife resampling was then used to reduce bias of the predictions and estimate their uncertainty. Th...

Accurate methods quantifying whole landfill surface flux of methane are important for regulatory and research purposes. This paper presents the results from the analysis of chamber measurements utilizing geospatial techniques [kriging and inverse distance weighting (IDW)] to arrive at an estimation of the whole landfill surface flux from the spatially distributed chamber measurement points. The...

Abstract Fine particulate matter (PM 2.5 ) is widely concerned for its harmful impacts on global environment and human health, making air pollution monitoring so crucial indispensable. As the world’s first open, real-time, historical quality platform, OpenAQ collects provides government measurement research-level data from various channels. However, despite OpenAQ’s innovation in providing us w...

The Multicriteria Decision Analysis (MCDA) and Geographical Information Systems (GIS) are used to provide more accurate decisions to the decision makers in order to evaluate the effective factors in the natural science. One of the popular algorithm of multicriteria analysis is Ordered Weighted Averaging (OWA). The OWA procedure depends on some parameters, which can be 15 specified by means of f...
