Global System for Mobile Communications (GSM) started operations in Nigeria on the 16th of May, 2001. An important feature communication system is Base Transceiver Stations (BTS). However, their installations have brought about public concerns and fears, specifically to issues relating environmental risk, health sometimes construction problems that might result mast collapse. This study aimed a...

Daerah Aliran Sungai (DAS) Pekalen yang terletak di wilayah administrasi Kabupaten Probolinggo, Provinsi Jawa Timur bermuara Selat Madura dan bersumber dari Gunung Argopuro Lemongan mempunyai luas sekitar 1.696,17 km2 . Penyebab terjadinya banjir Probolinggo pada tahun 2018 2019 kemungkinan dikarenakan banyak terjadi penebangan pohon hulu DAS Kali pekalen didominasi sengon hutan masyarakat, sel...

Imagery integration has a variety of open questions in image registration, conflation, and search. A new promising approach is based on the algebraic paradigm that differs from the more traditional geometric and topological approaches. In previous research, algebraic methods have been based on algebraic structural analysis of features represented as open polylines called linear features. In thi...

West Nile virus (Flaviviridae: Flavivirus) is a serious infectious disease that recently spread across the North America continent. A spatial analysis tool was developed on the ArcMap 9.x platform to estimate potential West Nile virus activity using a spatially explicit degree-day model. The model identifies when the virus Extrinsic Incubation Period (EIP) is completed within the vector longevi...

Given the above model of stationary random spatial effects { ( ) : } s s R   , our ultimate objective is to apply these concepts to spatial models involving global trends, ( ) s  , i.e., to spatial stochastic models of the form, ( ) ( ) ( ) , Y s s s s R      . In continuous spatial data analysis, the most fully developed models of this type focus on spatial prediction, where values of ...

Introduction: Geographic information systems (GIS), and more specifically remote sensing, have been used within the geosciences for well over two decades. In that time, the ability to handle a variety of increasingly voluminous data (both vector and raster) has allowed continued data analysis and exploitation within mainstream GIS. The uptake and use of GIS has not been mirrored within the plan...

Introduction: We have explored the use of GIS suitability models for the screening and analyzing of potential sites for Mars landers using engineering and scientific constraints in an iterative manner. While initially performed on locally held data sets, these analyses have now been extended to use widely distributed data from standardized Web Mapping Servers (WMS) [1]. The ability to exploit a...

Modelling and classification difficulties are fundamental issues in natural hazard assessment. A geographic information system (GIS) is a domain that requires users to use various tools to perform different types of spatial modelling. Bivariate statistical analysis (BSA) assists in hazard modelling. To perform this analysis, several calculations are required and the user has to transfer data fr...
