I am interested in developing a mobile app to track GPS devices, and am curious which among the mobile-friendly mapping sources would best meet my needs.
I'm looking for either a free service, or a low-cost one, which is scalable, lightweight and able to render points quickly.
My source data will have 10-20 thousand records (and hopefully more moving forward), and approximately 20 fields of data, although my API might not expose all records and all fields depending on the call.
Note that I'm interested in using a framework such as PhoneGap or Ionic to develop in one language and compiled into native Android or iOS code. If there are considerations for how the different free or low-cost mobile-friendly mapping sources would play with those frameworks (or the code they produce), thoughts on that would be appreciated.
