It's a Matter of Precision

To achieve universal geolocation (or geolocation works in older browsers and devices), there are three primary options for polyfilling geodata:

1. Plug-ins - Browser add-ins that help polyfill geo abilities
2. IP-Based Location - Less precise, but useful for "general" location
3. Targeted Degredation - No geo-enrichment for older browsers
