This repository contains the source codes for noter-frontend, which is a free to use online tool with the following two major functionalities:

1. Annotate histroical images of buildings with the constituent components (e.g. facade, windows, entries, stairs, etc)

2. If the building footprint is available, associate the annotated building facades with the building footprint: one annotated building facade can only be associated to one side of the footprint polygon, which are correponding to each other physically.

This repository is built on top of makesense.ai, which is a free to use online tool for labelling photos.
