I've got plans of my house and a warehouse on paper. I would like to scan them in JPEG, import them on my PC and measure them. I'm looking for a website where I can upload those tiff, jpeg or pdf files, define a scale (measuring something of known measure to give a correct scale to the entire image), measure the rooms by drawing polygons over them, and print out the images with my measured polygons or send them to my email with the total area reported. I can't find anything like this on the web. Is this kind of utility uncommon? Can any body suggest a simple solution for measuring my planimetry without installing any software?
