$1.$ What is the maximum pixel size you can tolerate if you want your image file to be equal to or less than $100$ Megabytes $($MB$)?2.$ Assume a photo has a photo resolution of $25$ line pairs per millimeter $($lpr$/$mm$).$ a$)$ What is the corresponding pixel size in micrometers $($m$)?$ b$)$ Compute the number of dots per inch $($dpi$)$ necessary to scan the pixel size necessary to capture photo resolution of $25$ lpr$/$mm$.$ c$)$ What is the ground pixel size with a photo scale of $1/480?3.$ Given a scanned photograph at $1250$ dpi possessing a scale of $1=480$ a$)$ Compute the image pixel size in micrometers $($ m$).$ b$)$ Compute the ground pixel size in feet. $4.$ What advice does Dr$.$ Welch give on how to set the proper scanning resolution for a photograph upon which you wish to make measurements. $5.$ Your job is to build panels to be placed over corners on a section line to allow photo identification. The flying height is planned at $4,000$ feet above sea level. The average elevation of the section line is $340$ feet. Compute the required dimension of D in feet. Assume that in order for the entire panel to be photo identified as an object, D must be $0\mathrm{.}05$ millimeter in the photograph. $6.$ Dr$.$ Welch gives the rule of thumb that it takes four pixels to provide identification of the shape of a feature. Given a flying height of $1500$ feet over terrain, compute the scanning resolution $($in dpi$)$ necessary to clearly photo$-$identify the center panel of the target.
