Maps are a very important part GIS Kit/Pro. Garafa's proprietary map engine is the result of years of work as one of the leaders in the GPS apps in the App Store. Through ongoing optimization it has become what we believe is the fastest custom map engine available on the iOS platform.
All maps in GIS Kit/Pro use a mercator projection is used due to its popularity and some of its computing advantages. This limits the data to being roughly between ±85° in latitude. It also exaggerates the size of the geography the further you are from the equator. To verify this, watch the map scale change as you pan the map in the vertical direction--it changes!
Typical iOS map gestures are supported, namely:
- Pinch to zoom in/out
- Drag finger to pan
- Double-tap to zoom in
- Two-finger tap to zoom out
