About The Project

This project was done during the winter term 2024/25 at ifgi Münster as part of the Spatial Information Search Course of the Master in Geoinformatics.

In this project a collaborative and interactive Web-Application was implemented. The App includes a Chatbot which is linked to a leaflet map. It is knowledged about the geometries and the federal relations of Northrhine-Westphalia.

It consists of multiple components, which will be explained in the following:

In order to use the chatbot, one has to enter a purchased Open AI API Key The field for entering the key opens on loading the /chat page.

On the left side of the page is the chat where you can asks questions similar to our listet examples. After asking the question the chatbot takes some time to generate the answer. When the answer is computet, the named entities in question and answer are visualized on the right side on the leaflet map.
