The measurement of tree height has long been an important attribute for the purpose calculating growth, volume, and biomass, which in turn deliver ecological economical information to decision makers. Tree traditionally measured by indirect field-based techniques, however these methods are rarely contested. With recent advances Unmanned Aerial Vehicle (UAV) remote sensing technologies, possibility acquire accurate heights semi-automatically become a reality. In this study, photogrammetric...
Abstract Spatial Data Infrastructures (SDI) have been widely accepted to exchange geospatial data among organizations. Today SDIs main focus lies on the provision of in form distributed spatial web services, retrieval through catalogues, and visualization Web Map Services (WMS). The hypothesis presented this paper takes SDI's one step further by providing a method process geodata an Open Geospatial Consortium (OGC) compliant way into information. Two case studies present potential...
The objective of this study is first, to investigate the level heavy metals in soils from Agbogbloshie e-waste processing site (AEPS), degree at which these contaminate area and finally, assess carcinogenic non-carcinogenic health risk on workers residents around AEPS. 132 soil samples were collected analyzed for Ba, Cd, Co, Cr, Cu, Hg, Ni, Pb Zn after appropriate preparations made. Results analysis showed mean concentrations Cr Ni considered as lower than permissible levels Dutch Canadian...
Fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith), damage was monitored at a regional scale using time series data in Western and Southern African countries. The study employed the normalized difference vegetation index (NDVI) computed from Landsat 8 imagery Google Earth Engine (GEE) image composites for years 2013 to 2020 areas. then reclassified based on NDVI threshold values into low, sparse, moderate, dense classes. FAW prevalence were utilized validate correlation between...
This study examined the spatial distribution and extent of soil contamination by heavy metals resulting from primitive, unconventional informal electronic waste recycling in Agbogbloshie e-waste processing site (AEPS) Ghana.A total 132 samples were collected at 100 m intervals, with a handheld global position system used taking location data sample points. Observing all procedural quality assurance measures, analyzed for barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu),...
Upgrading all slums in Lagos by 2030 will an ambitious task, given that more than 70% of its residents resides slums. Furthermore, there is no recent study identifying neither the nor their temporal growth/development pattern can backstop any slum management initiative. This aims to contribute applying object-based image analysis and intensity map link patterns processes growth Lagos. RapidEye imagery from 2009 2015 were used create maps for each time point six land use categories (water,...
This study evaluates the potential of repeat-pass synthetic aperture radar interferometry (InSAR) coherence for grasslands monitoring in Eastern Cape Province, South Africa. We used 12 pairs InSAR data Interferometric Wide swath mode (IW), VV-polarization (with different spatial baseline B⊥ and temporal repeat intervals between subsequent acquisitions), covering area during two growing seasons; drought season (2015/2016) non-drought (2016/2017). Results show that has higher variability...
The hydrological response of a watershed is key aspect management. Long-term monitoring faced with lack empirical data. This study implements Cook’s method to determine the run-off coefficient in Cisangkuy watershed. involved characteristic data such as slope, soil, stream, and vegetation greenness. Run-off related greenness, component responses, retrieved from satellite imageries (Landsat series) over 30 years using Google Earth Engine were used for this analysis. High-density areas tended...
The rapidly increasing annual global volume of e-waste, and its inherently valuable fraction, has created an opportunity for individuals in Agbogbloshie, Accra, Ghana to make a living by using unconventional, uncontrolled, primitive crude procedures recycle recover metals from this waste. current form recycling releases hazardous fractions, such as heavy metals, into the soil, posing significant risk environment human health. Using handheld positioning system, 132 soil samples based on 100 m...
Grasslands are a major component of the natural vegetation in South Africa, it covers almost one-third country's land surface. The current study focuses on assessing impact drought stress communal and commercial grasslands Eastern Cape Province using multi-temporal analysis Sentinel-1 SAR data. Data included retrieval biophysical parameters backscattering coefficients. Correlation was performed between data NDVI values derived from Landsat-8 optical A linear mixed-effects regression for...
This paper aims to design a method of multi-source data fusion in multi-target collaborative navigation. First, the respective features GPS/INS/RS/MO navigation process are clarified. Then is designed including GPS/INS with adaptive Kalman filter, RS/MO ranging table matching observation targets, and joint adjustment fused data. Finally, simulation experiment carried out verify improvement positioning efficiency precision. The results show that based on can increase stability accuracy service.
The high mining potential of the Peruvian Andes has promoted booming foreign investments. activity takes place on campesino community lands and headwaters. Once government awards a concession, companies must regularly negotiate land rent with communities over whole duration operation, often leading to disagreements. Our research objective is identify impacts farming activities in Junin region, central Andes. Using mixed-methods approach involving in-depth interviews, water soil analysis,...
Abstract The mining industry is susceptible to the effects of local climatic changes just as surrounding socioecological systems are exposed both and changing climate impacts. Adaptation deficit in a worldwide problem but given double exposure systems, which has emergent outcomes on industry, operations must adapt coexist with rural communities. To understand this susceptibility, study employed mixed methods assess implications sustainability perceived among Ghanaian through lens corporate...
