Geographic Information System (GIS) software has evolved to the point where it is extremely valuable to the planning, construction and operation of pipelines across a range of industries. Recently, GIS software of high quality has become freely available for use and modification under open source licensing schemes. This paper evaluates the utility of a geographic information system prepared using open source software for shared departmental use. Analysis includes areas such as functionality of the software, setup time, and total cost of ownership. The departmental focus is at a level concerned with pipeline planning and cost estimating. The full GIS package used for the analysis consists of a database, spatial data management software, and a web server providing web-based access to geomatic data suitable for a pipeline construction department. The utility of application programming interfaces provided through the GIS with open source software development tools is analysed in the form of a what-if economic comparison tool for pipeline route selection. The ability of the GIS to integrate data from other departmental systems is also examined. Final conclusions serve to aid pipeline GIS teams in determining if open source solutions are ready for widespread use.

QGIS is a free and open-source software that allows viewing, editing, and analyzing georeferenced data. It is a Geographic Information System (GIS) software composed by tools that allow to manipulate geographic information and consequently to create maps which help to get a better understanding and organization of geospatial data. Unfortunately, maps created directly in the GIS desktop software are not automatically transferred to a website. This research aimed to compare publishing capabilities in different QGIS plugins to create Web Maps. This study analyzes four QGIS plugins (QGIS2Web, QGIS Cloud, GIS Cloud Publisher and Mappia Publisher), performing a comparison between them, considering their advantages and disadvantages, the free and subscription plans, the tools offered by each plugin and other generic aspects. The four plugins were tested in a specific case study to automatically obtain different Web Maps. This study could help users to choose the most adequate tools to publish Web Maps under QGIS software.

Geographic Information System (GIS) is a tool used for capture, storage, manipulation, query and presentation of spatial data that have applicability in diverse fields. Web GIS has put GIS on Web, that made it available to common public which was earlier used by few elite users. In the present paper, development of Web GIS frameworks has been explained that provide the requisite knowledge for creating Web based GIS applications. Open Source Software (OSS) have been used to develop two Web GIS frameworks. In first Web GIS framework, WAMP server, ALOV, Quantum GIS and MySQL have been used while in second Web GIS framework, Apache Tomcat server, GeoServer, Quantum GIS, PostgreSQL and PostGIS have been used. These two Web GIS frameworks have been critically compared to bring out the suitability of each for a particular application as well as their performance. This will assist users in selecting the most suitable one for a particular Web GIS application.

This work assesses sea-level rise using three different models created on Free and Open-Source Software for Geographic Information System (FOSS4GIS). Based on regional projections of Special Report on Climate Change and Oceans and Cryosphere (SROCC) of the Intergovernmental Panel on Climate Change (IPCC), the models were applied to a case of study on Rio Grande do Sul coast – Brazil under different sea-level rise scenarios by the end of this century. The End Point Rate for QGIS (EPR4Q), calculates a shoreline projection using End Point Rate method. The Uncertainty Bathtub Model (uBTM), analyses the sea-level rise impact by the uncertainty of sea-level projec-tions and vertical error of the Digital Elevation/Terrain Model (DEM/DTM). The Bruun Rule for Google Earth Engine Model (BRGM) predicts the shoreline position with sea-level rise, using topographic and bathymetric data from Unmanned Aerial Vehicles (UAV) and Coastal Modelling System (SMC – Brazil), respectively. The results indicated a maximum shoreline retreat for 2100 of -502 m and -1727 m using EPR4Q and BRGM, correspondingly. The uBTM using the land-use of Mapbiomas showed a maximum of 44.57 km2 of urban area impacted by the sea-level flood. This research highlights the possibility of performing coastal management analysis in GIS environ-ment using non-commercial software.

The dawn of the age of computerization has opened up a new horizon and paradigm in the decision making process and dissemination of information. In the past difficulties arise when a large bulk of data representing of modeling a certain phenomenon was to be compiled because these data were often detached from each other. With Geographic Information System (GIS), the storing, administration, processing, manipulation, analysis and exhibition of important data in a system of information can be done with ease and speed. This study attempts to represent and model the available data of Sourt Aceh Selatan concerning its administrative boundaries, land, geology, land use and slope, Using ArcGIS 10.3, a GIS software that is capable to represent spatial data as well as attributes of the study areas. the results of rms error on landsat 8 oil images obtained mean 0.51, GIS technology in civil engineering work is normally used in the planning and preparation of a new land for the development of a housing complex.

Рассматривается необходимость разработки специализированной геоинформационной системы для отрасли охотничьего хозяйства. Указаны основные принципы проектирования и разработки приложения. Определены необходимые требования к проектируемой ГИС и задачи, которые способна решать система. Проведено описание организационной структуры геоинформационной системы и функции, подлежащие визуализации. Составлено схемотехнические решение и визуализация графического интерфейса взаимодействия пользователя с системой. В соответствии со Стратегией развития охотничьего хозяйства РФ до 2030 года, требуется повышать программно-информационное обеспечение охотпользователей. Обоснованием разработки является отсутствие единой системы сбора, хранения и систематизации данных о состоянии охотхозяйств, численности популяций и проведении необходимых мероприятий. Разработка специальной ГИС способна обеспечить поддержку в системе принятия решений человеком в интересах управления территориями охотхозяйств. Разработка продуманного интерактивного интерфейса позволит вывести ГИС на наиболее качественный уровень взаимодействия. Общеизвестно, что пространственные данные являются основой информационного обеспечения геоинформационных систем, в том числе локальных ГИС. Для непрерывного обновления геоданных требуется своевременная актуализация информации на сервере, в которой данная система развернута. Поэтому в качестве технологической основы выбрано проектирование именно веб-приложения, работающего через предустановленный браузер пользователя. Реализация функций данной ГИС, продуманный человеко-машинный интерфейс, включенный в ее состав, позволит использовать данную систему не только охотпользователям, но и заинтересованным специалистам в смежных отраслях: лесное хозяйство, картография, геоинформатика, зоогегография, охотоведение. Разработанная система может использоваться в учебном процессе при подготовке студентов по различным направлениям в высших образовательных учреждениях. Discusses the necessity of developing a specialized geographic information system for hunting groung. Carried out a description of the organizational structure of geoinformation systems and functions to be rendering. Determined necessary requirements for the design of the GIS and the tasks which the system are able to solve. The organizational structure of the geographic information system and the functions to be visualized are described. Compiled technical scheme and visualization GUI. In accordance with the strategy of development of the hunting industry of the Russian Federation until 2030, it is required to increase the software and information support for hunting users. The basis for development is the lack of a unified system of collection, storage and systematization of data on the state of hunting, population and carry out the necessary measures. The development of a special GIS is able to provide support in the system of decision-making by a person in the interests of managing the territories of hunting farms. The development of a thoughtful interactive interface will bring the GIS to the most high-quality level of interaction. It is well known that the spatial data are the basis for information support of geographic information systems, including local GIS. For continuous updates of the geodata requires a timely update information on the server in which the system is deployed. Therefore, as the technological base of the selected design it is the web application running through a preset user's browser. The implementation of the functions of this GIS, intelligent man-machine interface, included in its composition, will allow you to use this system not only hunters, but also to interested professionals in related industries, forestry, cartography, geoinformatics, zoogeography, and hunting. The developed system can be used in educational process for training students in various areas in higher educational institutions.

The increasing need for property in Tanjungpinang City is very growing, especially in the housing sector. Selection of property based on location and facilities and infrastructure is always a consideration for the community in making decisions to buy a property. Difficulty finding property location information in a certain area often occurs, resulting in people not getting references about the properties offered in Tanjungpinang City. The purpose of this research is to create a web-based geographic information system (GIS) regarding the distribution of the number of properties on offer, especially in Tanjungpinang City using a web-based mapping approach. In the development of Property GIS the author uses the Waterfall method and in the analysis of system requirements it is modeled with UML (Unified Modeling Language) and implemented with the PHP programming language and MySQLI database. It is hoped that the results of making this property's geographic information system can help the public to find out information about the distribution of properties offered, such as the location of property coordinates, addresses, prices, property photos, property specification data and property developer data.
