Ndvi And Lst Extraction Of Modis Data Under A Gis Open Source Application - Rickettsia Study Case In Angola, Ana Cláudia Teodoro, Lia Duarte, Patrícia Barradas, T. L. Mateus, Zoraima Neto

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Fevers of unknown origin can have different aetiologies. The overlapping symptomatology of rickettsial infection and other endemic diseases that cause fever leads to a misdiagnosis or under-diagnosis of spotted fever group of Rickettsia (SFGR).

To better understand the epidemiology of this vector-borne disease in Angola, a comprehensive seroprevalence study was conducted investigating the exposure to SFGR in a sample of 92 febrile, Malaria and Yellow Fever negative human plasma specimen, collected to the study of the national surveillance of febrile syndromes between 2016 and 2017, in Angola.

The seroprevalence of IgG antibodies against SFG Rickettsia in humans was calculated by …

Land Suitability Assessment For Cash Crops Using Geospatial Techniques, Albert B. Jubilo, Glenn D. Depra, Aurecel L. Alejandro

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Land suitability assessment studies for cash crop production in certain areas provide opportunities and limitations to decision makers and farmers. The objective of this study was to assess the suitability of land for banana, corn and cacao cultivation and production in Davao Region, Philippines. The methodology adopted combines most aspects of climate, temperature, slope and soil type that affect crop suitability at large. Suitability maps of the region for cash crop cultivation were established by scanning and digitizing the soil maps using geospatial techniques. Bananas are best suited for Davao del Norte. Corn are good for Davao del Norte and …

Race And “Hotspots” Of Preventable Hospitalizations, Caryn N. Bell, Janice V. Bowie, Roland J. Thorpe Jr.

Journal of Health Disparities Research and Practice

Abstract

Preventable hospitalizations (PHs) are those for ambulatory care-sensitive conditions that indicate insufficiencies in local primary healthcare. PH rates tend to be higher among African Americans, in urban centers, rural areas and areas with more African American residents. The objective of this study is to determine geographic clusters of high PH rates (“spatial clusters”) by race. Data from Maryland hospitals were utilized to determine the rates of PHs in zip code tabulation areas (ZCTAs) by race in 2010. Geographic clusters of ZCTAs with higher than expected PH rates were identified using Scan Statistic and Anselin’s Local Moran’s I. 10 PH …

A Learning Vector Quantization Based Geospatial Modeling Approach For Inland Wq Remote Prediction

Journal of Spatial Hydrology

Quick and accurate quantification of lake water quality (WQ) is essential for its management and improvement. Use of geotechnology (remote sensing, GIS, and GPS) applications is a step forward in improving our ability to effectively quantify and manage the WQ of ungauged lakes. Beaver Reservoir, a drinking water source for over 280,000 people in northwest Arkansas, is facing increased chlorophyll-a (Chl-a) and suspended matter (SM) content in the lake. This study is designed to qualitatively predict the Chl-a and SM content in the lake on a spatial basis from Landsat-TM image digital information. A Learning Vector Quantization (LVQ) classification neural …
