I'm in progress of creating NFC based app for parking lot solution. So basically when user taps their NFC enabled phone to the tag, they'll be shown a map of the parking lot. From there, user will be able to tap into one of the empty parking spots. When user arrives at the location, they have to tap their smartphone to another tag, confirming their location.
Currently, I'm having trouble with displaying the map. Should I use Google Map and get the lat and long of the parking lot (it's outdoor) or is there any other method of displaying it? Such as maybe using a picture?
Addition : There will be several parking areas, such as A, B, C parking and several slots too. So when user taps parking area A, user will be given an animation of zooming in to parking lot A and new image will be displayed showing the overview of area A.
When user taps the empty slot, that slot will be reserved (still not going here yet, having confusion with showing map image)
The Google Maps Android SDK is your best option.. if you have an accurate sketch of the parking lot you use as a custom tile in the map
