Produce dimensioned drawings from photos

I draw CAD architectural plans - when I carry out a survey of a property I take digital photgraphs of each external elevation of the property. Is there some way of determining sizes from these photographs (heights) so that technicians in office can draw the elevations without me having to physically measure heights on site - all horizontal measurements are taken on site - so horizontal sizes will always be available. Example - height and position of windows/doors - height of building - pitch of roof, etc. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
