Abstract

The Geographic Information Systems (GIS) are systems capable of handling, manipulating and refining geographic data. It is becoming increasingly useful as a tool for making decisions about urban, rural and environmental problems. Nowadays, with the information age, the internet gradually becomes part of the citizen's daily life. With the accelerated development of the Internet, the processing methods and the GIS data have also evolved, being accessed, shared and manipulated dynamically on the Internet. The term WebSIG refers to geographic information systems on the Internet, which provide interactive spatial data to users through an Internet browser or intranet. In recent years, the demand for agroecological (organic) products has been growing, for the growing search for natural products, free of pesticides and for the need to preserve the environment. Aiming to contribute to the dissemination of the agroecological products of the municipality of Teresina, the present work presents the development of a WebSIG application to make available information on the food production and distribution network from the agroecological practices of Teresina, Piauí. For the development of the application, it was used entirely of open source software and tools (Open Source), where it was first carried out the survey of the data of the network of production and distribution of agroecological foods of the municipality of Teresina. In order to standardize the data, the Qgis software was used, and the PostgreSQL Database Management System (SGBD), with its PostGIS spatial extension, was used to implement the database. Leaflet mapping library was used to provide geographic information in the form of maps and for the construction of the page, tools and functionalities of the application was used HTML markup languages, CSS and PHP and Javascript programming languages. The result of the work was a system capable of providing the information (products, images, description, location, among others) of the producing units, fairs and trades of agroecological basis of the municipality of Teresina. The application aims to shorten the path of the consumer to the producer, creating healthier relations and strengthening the market of agroecological products of the municipality of Teresina.
