Desenvolvimento de WebSIG para apoio na selecção de áreas mulltifinalitárias aplicando análise multicritério. estudo de caso: distrito municipal de Katembe

Abstract

This work aims to develop a web-based Geographic Information Systems tool to support the selection of multi-purpose areas by applying multi-criteria analysis for the municipal district of KaTembe. It aims to help users with or without experience in Geographic Information Systems and multi-criteria analysis to make spatial decisions intuitively. The objectives of this work focus on the development of a WebGIS that contains data entry and visualization tools, using tools such as HTML markup language and CSS styling that together make up the Bootstrap library, responsible for developing the user interface. Using the Python programming language, libraries such as Flask for interaction between backend and frontend, geopandas and shaply for manipulating spatial data and numpy for calculations of the Hierarchical Process Analysis method, it was possible to develop a robust and flexible logic regarding the system's functionalities. In addition to the backend, a simple database was created using SQLite with the spatial extension spatiaLite to allow the storage of spatial data to be used in the system. The combination of all these tools and methodologies results in the present work, which is an Internet-based Geographic Information System to support the selection of multipurpose areas applying multicriteria analysis, as a tool that promises to help any user to spatially search for areas suitable for housing, commerce or agricultural practice from a user-friendly interface and without technical aspects that require prior studies.
