What is being done?

Well I am importing jpgs of our buildings in to cisco location appliance servers, then mapping where the access points are for user tracking, heat maps, user/asset tracking etc.


What is needed:

So I need an application that I can take a jpg of a floorplan, crop it (easy I know), but also help me measure the length and width of the building in the floor plan.

I saw one image editing program that has a ruler built in and you can measure a single or double doorway on the ruler ( 3 or 6 ft respectively) then enlarge the ruler to cover the wall of the floor plan, and get the over all length or width that way.

Any one know of an application like this?

sounds like you need a CAD program, not an image editor

photoshop can do all of this pretty damn easiliy if you know any definite dimension on the plan. Measure, change the ppi (say you have a 10 ft wall and it measures 480 pixels, you'd make sure the image IS NOT resampled and change the resolution to 4ppi) so you have some easy multiple to measure the stuff you need. Using the ruler tool would let you measure any direction and look at the L1 dimension (shown in pixels) to find the length. If you crop the image you can then just look at the pixel dimensions and you'll know how big the room is.

Hell, this is actually over -complicating things a tad. Just measure the known distance, measure the overall distance, divide the pixel measurements the ruler tool gives you.

The problem is that there isnt a known distance on the floor plan. Its just a drawing, no sq footage info on the drawing. Well we know how wide a door frame is since all the doors are commercial 3 ft standard, but thats about it.

^that's typically how architects do it too, find a door, measure it, that's 3ft. (90% of the time) if you don't have a scale for a drawing

i mean we'd usually just bring the raster image into CAD, scale it up until the door is 3ft, then just trace it.
