ISPRS Catalogue for geospatial educational resources

This is a pilot catalogue for geospatial educational resources that was developed as part of the 2018 ISPRS Scientific Initiatives grant. You can read more about the catalogue and implementation in this conference article, https://www.int-arch-photogramm-remote-sens-spatial-inf-sci.net/XLII-2-W13/1609/2019/

For the backend of the catalogue, I used Google Firebase, a cloud-based NoSQL database that allows developers to quickly setup a backend for any web application. The front-end or user interface of the catalogue was developed using JavaScript and specifically the React library.
