Abstract: Water is a basic element of social and economic infrastructure and is essential for healthy society and sustainable development. Due to rapid increase in density of population, fast urbanization, industrialization and agricultural use, the demand of water is increasing day by day. As a result, surface water and ground water level is decreasing. Pollution and increased demand have made good quality water scarcer and expensive. Groundwater is the favourite alternative and is facing threats due to anthropogenic activities, which has lead to deterioration in ground water quality. The possibility of ground water contamination is due to the mixing up of toxic chemicals, fertilizers, waste disposed from industrial sites etc. Hence monitoring of ground water quality has become indispensable. GIS not only facilitates data capture and processing but also serve as powerful computational tools that facilitate multimap integrations. In this project ground water quality analysis was carried out for Chavara Taluk in Kollam District. It was reported that groundwater and surface water around the study area was affected due to effluents from the industry. Water samples were collected from all around the taluk, and the strategically analysed results will be presented in a GIS based water quality mapping suggesting remedial measures for the study area.

This document was created for a course at Seoul National University in the Spring 2019 semester. In this document, there are references to the “eTL” which hosts files needed for the training exercises. The eTL is the university’s online classroom environment, which is not available to non-SNU users. Therefore, I have created space in my Google Drive (link in the Training Manual), where members of the general public can access the files needed for the training. If you cannot access the information for some reason, please email me at daudi.wright@gmail.com and I will help you access the information you seek. Many of the assignments refer to data that is not publically available (for example, the real 14C data from Korea, which the research group headed by Dr. Jangsuk Kim is working with). Unfortunately, these data are under study and cannot be released without prior consent. If you have a compelling reason to access the data, queries should be directed to Dr. Kim. This manual is released in Word format to the general public and you are free to reuse and modify the content as you see fit, but this material cannot be copyrighted by any entity. I have created the content in the spirit of open dialogue and collaboration.

Neste livro apresentamos uma visão geral do QGIS demonstrando suas ferramentas no contexto do ordenamento territorial municipal. São 15 capítulos nos quais tratamos de algumas questões conceituais, da base cartográfica municipal, dos mapas de geologia, geomorfoogia e solos. Apresentamos capítulos específicos para tratar dos modelos digitais de elevação e do compositor de impressões.

This paper describes a new tool for eye-tracking data and their analysis with the use of interactive 3D models. This tool helps to analyse interactive 3D mod-els easier than by time-consuming, frame-by-frame investigation of captured screen recordings with superimposed scanpaths. The main function of this tool, called 3DgazeR, is to calculate 3D coordinates (X, Y, Z coordinates of the 3D scene) for individual points of view. These 3D coordinates can be calculated from the values of the position and orientation of a virtual camera and the 2D coordinates of the gaze upon the screen. The functionality of 3DgazeR is intro-duced in a case study example using Digital Elevation Models as stimuli. The purpose of the case study was to verify the functionality of the tool and discover the most suitable visualization methods for geographic 3D models. Five selected methods are presented in the results section of the paper. Most of the output was created in a Geographic Information System. 3DgazeR works with the SMI eye-tracker and the low-cost EyeTribe tracker connected with open source applica-tion OGAMA, and can compute 3D coordinates from raw data and fixations.

Minicurso ministrado durante o VI Workshop Internacional Sobre Planejamento e Desenvolvimento Sustentável de Bacias Hidrográficas, realizado entre os dias 11 e 15 de julho de 2017, na Universidade Federal de Uberlândia, MG. O minicurso tratou de dados e suas aplicações utilizando o QGIS como plataforma de trabalho. Os dados hidrológicos foram extraídos a partir da ferramenta TauDEM.
