Starting a thread to discuss google maps alternatives.
supercharge.info source code is now here:
Some options (collecting suggestions sent to firstname.lastname@example.org):
- open source mapping provider Leaflet
- Esri maps as for what you need, it will cost you $0 per month. You can find more info at developers.arcgis.com
- Continue to use google maps but charge say $50/year for capability to use street view and routing (most expensive features, as far as I can tell).
supercharge.info has been averaging about 3,000 unique visitors per day with occasional spikes to 4k or 5k. Looks like the google maps cost was just under $60/day when I shut it down.
