Im building a website for roofing estimates. The website get the premises address and genetates a bird eye view of the building. The tech stack I want to use is Next.js, node.js Postgresql or MongoDb.

After getting the picture, user will be able to draw lines over the roof and calculate different areas of the roof with an accuracy percentage like 5% accuracy etc.

After calculating the areas an automatic report will be genrated for cost estimates or material estimates etc.

I can’t find any resource to get the high quality images of the premises/building.

I am also confused how to achieve the functionality of drawing lines and calculating the areas.
