Now imagine that the house didn't exist anymore - it was destroyed, but some historic photos exist. Then, if you can determine the scale of the photos, it must be pos- ble to get the desired data. Of course you can use photos to get information about objects. This kind of - formation is different: So, for example, you may receive qualitative data (the house seems to be old, the walls are coloured light yellow) from photo interpre- tion, or quantitative data like mentioned before (the house has a base size of 8 by 6 meters) from photo measurement, or information in addition to your background knowledge (the house has elements of the \"art nouveau\" style, so may be c- th structed at the beginning of the 20 century), and so on.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45281288454295,"sku":"9783642445170","price":10650.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783642445170.webp?v=1769298793","url":"https:\/\/atlanticbooks.com\/products\/digital-photogrammetry-a-practical-course-9783642445170","provider":"Atlantic Books","version":"1.0","type":"link"}
