Quote:quote:Moreover, the actual drawing of a feature is an interpretation in itself... from the actual drawn section, the scribbled interpretative notes that may go with it, right down to the mud-encrusted permatrace that arrives into the office (it can be indicative of site conditions, the weather, the actual soil type and the mind-set of the excavator!). Site photography... a photograph taken using the equivalent of a box-brownie (ok a realtively cheap manual SLR) will be far, far, far better in resolution and contrast range than anything a current 10 to 12 megapixel can produce. There is also the issue of preservation; there are many tales of hard drives crashing or being stolen, or of CDs that held thousands of images being damaged. Unlike film, where there is the not positive to rely on, digital images are intangible and most of the time, stored on computers.
Hear hear!
