Cadastral maps

Cadastral maps are used by many people and play a large role in realestate and county and state work. These maps show property ownership and their boundaries. For example, you can go down to the city hall and get what is called a platt book. These books will have maps of the whole county showing who owns what land. http://www.google.com/imgres?imgurl=http://history.youle.info/gracemere/images/Gracemere_cadastral.jpg&imgrefurl=http://history.youle.info/gracemere/maps.html&usg=__fGTxftP7z1h9dKX9o_a2qhgISTQ=&h=496&w=641&sz=148&hl=en&start=82&zoom=1&tbnid=rqG_elJdGZBbFM:&tbnh=117&tbnw=151&ei=EjwiTob4M8OTtwevhtCVAw&prev=/search%3Fq%3DCadastral%2Bmaps%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1363%26bih%3D740%26tbm%3Disch&um=1&itbs=1&iact=hc&vpx=166&vpy=397&dur=6414&hovh=197&hovw=255&tx=165&ty=134&page=4&ndsp=28&ved=1t:429,r:14,s:82&biw=1363&bih=740
