What is the scale of a Aerial photograph? I want know the scale of a aerial photograph use for Aerial photography I want to know common standard scales used for Aerial photograrammetry

What is the scale of a Aerial photograph used for aerial photogrammetry? what are common Standard scales

What is the formula used to solve this question? The scale of an aerial photograph can be approximated as the ratio of the camera's focal length to the airplane's altitude. The plane altitude is 305m and the camera focal length is 45mm. What is the diameter of the crater in the photo? **(there's a photo taken from on airplane with a crater in the center, sorry I can't upload the photo.)**

I need help with proportions? I have no idea how to solve proportional reasoning problems. One of the problems for my homework is to identify whether a constant multiplier or constant ration is used to solve problem. I don't even know what these are!! Haha. Here is an example: An aerial photograph has a scale of 3 inches equals 20 miles. If the photograph is 12 inches by 18 inches,how many square miles are represented? Create an equation/expression that relates these quantities and identify the representation as a CONSTANT MULTIPLIER or a CONSTANT RATIO. Please help me!

Aerial Photography by request in VA? I need an Aerial Photography company that does vertical photos by request. I need a buisness lot vertically photographed in VA by sometime next week. The photo needs to be digital, but it does not need to be to scale. I need an electronic copy of this photo as well. Any suggestions?? It's in Chantilly, VA.

Have any of you been to Anniston Army Depot and/or are good with aerial photography? I have a single aerial photograph of Anniston Army Depot and am hoping to construct a model of the railroad operations on this base. I was wondering if any of you had better photographs of the base rail facilities and/or would be able to provide me with more details from the aerial photo. http://maps.google.com/maps?hl=en&um=1&ie=UTF-8&q=Anniston+Army+Depot&fb=1&split=1&gl=us&cid=0,0,13256188318000757384&ei=YvCOSdXiL5KasAPZx-yOCQ&sa=X&oi=local_result&resnum=1&ct=image I enjoy constructing model trains and have recently begun considering constructing, from scratch, a train of DODX (department of defense railroad) flatcars. http://www.trainweb.org/marcrailfan/dodxflat2.html These railcars are apparently used to transport military equipment from around the country to Anniston Army Depot in Georgia where the equipment undergoes major repairs and upgrades. Once I have a decent number of these railcars, I was hoping to construct a scaled down version of Anniston Army Depot (I’ll likely build a layout that is only large enough to accommodate a portion of the 7 sidings and leave a switch leading to the others in case I ever want to build them) so that I could use the cars to make deliveries to the base. Furthermore, once the base is complete, I’d hope to construct a DODX 25 ton or 44 ton switcher to handle the switching within the base. http://www.rrpicturearchives.net/showPicture.aspx?id=1037617 http://www.rrpicturearchives.net/showPicture.aspx?id=884628 Unfortunately, I only have one picture of the base itself and it’s an aerial photo. Would any of you be able to help me identify more details from the aerial photograph or actually have some ground level photographs of the bases rail facilities??? http://maps.google.com/maps?hl=en&um=1&ie=UTF-8&q=Anniston+Army+Depot&fb=1&split=1&gl=us&cid=0,0,13256188318000757384&ei=YvCOSdXiL5KasAPZx-yOCQ&sa=X&oi=local_result&resnum=1&ct=image Specifically, what are the dimensions of the workshops that line the tracks? What would these buildings look like at ground level? Is there any kind of gate or security separating the base siding from the railroad mainline? If there is, what would it look like? Finally, what would the two large buildings on the south side of Roosevelt drive look like-what are there dimensions??? Any other information you could give me on this railroad operation would be greatly appreciated.

trouble with these three Geography R.F scale and Bar scale questions? I am stuck on these few questions ive looked all over for help and no one or no site seems to really help if anyone has an idea how i can solve these problems so i know the basic formula id really appreciate it . Question 1. A map of unknown scale shows two tv transmitting towers. On the map the towers are 1/2 inches apart and the actual ground distance between them is 1,000 feet. What is the R.F. of the map? Question 2. A straight stretch of road on an aerial photograph was found to be 500 yards long. The same road segment measured on a the photograph was three fourths of an inch. What is the R.F. of the photograph? Question 3 This one is real confusing because it doesnt give you much to go on or what to do. it shows a rectangle with to lines on the first line it is 1 0 1 2 3 4 5 6 7 8 9 10 and says kilometers underneath the second line goes.. 1 0 1 2 3 4 5 and says miles underneath the question goes like this...The bar scales shown appear on one of the new U.S.G.S. maps.(A) Derive the R.F. of the map first using the kilometer scale. (B) no do it using the mile scale (C) which of the two systems was easier to using in the derivation of the R.F.and why.. I dont know what or how to measure that...if anyone can help explain these three problems id really appreciate it. thank you very much for your help it is really appreciated ..i just had one problem ..with question one i get that you have to convert ...and there is 12 inches in a foot ...and you multiply that by a 1000 to get 12,000...but since the questions says its 1.2 inches...why do you then mulitply it by two?...if one inch is equal to 12,000 how can the remainder .2 be worth the same? sorry it is just confusing to me...thank you very much if you can help break that one down a little more

mathematics/geography related question? The scale of an aerial photograph can be obtained by dividing the focal length of the camera (151.76mm) by thaltitude of the plane above the ground (approx 5290 metres). 1. what is the scale of the original aerial photograph, to the nearest 1000? 2. How far on the ground is 1mm on the air photo? (calculations needed)
