GetYourMap
Rendered using OpenGL ES 2.0 and optimized to work offline. Based on recent data from OpenStreetMap. Includes
search and directions.
Feature:
 One line dependency from Cocoapods/Carthage on iOS or maven on Android.
 GLMap built to work offline. Map data stored in compact binary format and it's optimized for mobile rendering.
 Data is rendered on device using OpenGL ES 2.0, with style applied on the fly. It's easy to load your own data layers
from GeoJSON files and integrate layers to the map
 Everything on map could be customized very fast. MapCSS is used to describe map style.
