Journal of Applied Geospatial Information 2019-06-30T00:00:00+00:00 Muhammad Zainuddin Zainuddin Lubis, S.Ik., M.Si Open Journal Systems <p>Journal of Applied Geospatial Information (JAGI) is a national&nbsp;and international peer review journal published by Politeknik Negeri Batam.&nbsp;The JAGI&nbsp;is issued 2&nbsp;times a year in electronic form, publishes Original Research Articles (full papers and short communications) and Review (full and mini-reviews) in all aspects of result research in the field of science/engineering: terrestrial and marine (geomatics, geophysics, geography, geology, geographic information systems, remote sensing, cartography, oceanography, hydrography, marine science and technology).&nbsp;We encourage all interested contributors to submit their work for consideration.&nbsp;<a href=";1488529534&amp;1&amp;&amp;">e-ISSN (Online):&nbsp;2579-3608</a></p> Geospatialization of Spilling Facility From Spdc 2015 Oil Spill Reports of The Niger Delta Region of Nigeria 2019-01-21T01:30:51+00:00 Moses Dolapo Apata Diepiriye Chenaboso Okujagu Francis Thomas Beka <p>A hundred and thirty two (132) Oil spill Incidents that occurred in year 2015 based on the existing SPDC Oil Spill JIV Reports were studied using GIS. The JIV reports were downloaded and the requisite information was acquired and incorporated into ArcMap10.2 and they were analysed to produce different maps. Result shows that about 18,233.04bbl of Oil was spilled and an area of 1,718,091.88m<sup>2</sup> was impacted in year 2015.Pipelines account for 65.15% (86) of the spills, followed by flowlines 14.39% (19), Wellheads 13.63% (18) while others account for the rest. Pipelines are the most sabotaged Production Facility with 73.63 %( 81) of the Sabotage that occurred followed by wellhead13.63 % (15) and, flowline 10 % (11) while other Production Facilities account for the rest. This Study also shows that JIV Reports to an extent are a good and convenient tool for characterising Oil spills and the JIV culture should be encouraged. This study should be carried out on all JIV so that they are put in a Digital Format where they can be easily queried to produce the necessary information as needed.</p> 2019-01-21T01:30:50+00:00 ##submission.copyrightStatement## Spatial Targeting of Soil Loss Using RUSLE in GIS: the case of Asokore Mampong Municipality, Ghana 2019-01-22T04:11:08+00:00 Gift Dumedah Evans Kyeremanteng Ema Dari <p>Soil erosion is a serious environmental problem that is associated with societal impacts including flooding, poor water quality, and loss of plant nutrient leading to low agricultural productivity. Soil erosion wears away the top soil and is controlled by the interaction between several factors including rainfall, steepness of slope, length of slope, vegetation cover, and land management practices. This study developed Geographic Information System (GIS) graphical model based on the Revised Universal Soil Loss Equation (RUSLE), to calculate soil loss in the Asokore Mampong Municipality of the Ashanti region, Ghana. The estimated soil loss was examined the spatial patterns of soil loss and intensity per areas, as an important method for proper planning of management measures. The graphical model was developed using the popular open source GIS software, QGIS, ensuring the availability of the model, automation for any specific area, and its execution to the general public. Data sources used include Digital Elevation Model (DEM) derived from ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), soil properties data obtained from the Global Soil Grids, land cover data from the Global Land Cover by National Mapping Organization (GLCNMO), NDVI (normalized difference vegetation index) data from MODIS (MOD13Q1, 16 Day), and rainfall data from GPCC version 7 (Global Precipitation Climatology Centre). Our results show high levels of soil loss (in tons per hectare per year) in the Municipality, with the capability to spatially target mitigation measures leading to cost effective environmental management.</p> 2019-01-22T04:11:07+00:00 ##submission.copyrightStatement## The Paddy Cropping Calendar Map In Tidal Swampland Field Of South Kalimantan 2019-01-23T04:26:15+00:00 Nur wakhid Haris Syahbuddin <p>Tidal swampland is one of sub optimal land that potential as a backup of fertile field in Java island. However, due to the global climate change, negatively impact the paddy production including the cropping time that shifted year by year. Therefore, the objective of this study was to develop a cropping calendar map of tidal swampland in three conditions, i.e. dry, normal, and wet years. This map was developed by analyzing the relationship between precipitation and tide overflow data. Also, primary data from field survey and farmer questionnaire were used for verification. The area was delineated by cropping calendar combined with administration, climate, tidal swampland, and rice field map.&nbsp; Using this map, the cropping time in tidal swampland field can be potentially increased become twice a year. By proper cropping time, the paddy production in tidal swampland of South Kalimantan also potentially will increased directly.</p> 2019-01-23T04:18:03+00:00 ##submission.copyrightStatement## The Condition of Significant Wave Height and Wind Velocity in Makassar Strait during 2017 2019-01-23T05:29:36+00:00 Hanah Khoirunnisa Shofia Karima <p>This study aims to look at the conditions and characteristics of significant wave height and its relationship to wind velocity in the Makassar Strait in 2017. The data used in this study are bathymetry data from GEBCO with a resolution of 30 seconds, significant wave height data (Hs) with a resolution of 0.25 x 0.25 as well as wind velocity and direction with a resolution of 0.25 x 0.25 which are secondary data results from the European Center for Medium-Range Weather Forecasts (ECMWF) with a span of one year in 2017. The method used in this research is an analysis of the energy spectrum of significant wave height using Fast Fourier Transform. In addition, wind velocity and direction are processed by using GrADS software to see the visual conditions. Based on this study, it can be concluded that wind velocity is strongly associated with significant wave height values. This can be seen at each sample point in the Makassar Strait, where when the value of wind velocity is high, the value of significant wave height has the same conditions, and vice versa. The wind velocity value has a maximum value in the Makassar Strait during the east season with a value of more than 4.5 m/s. The highest energy spectrum occurs at point 3 in the Makassar Strait, which is 7303 m<sup>2</sup> with a period of 6 months.</p> 2019-01-23T05:29:35+00:00 ##submission.copyrightStatement##
