Bit Map provides mapping and navigation with offline maps (inc. JPEG, TIFF, PNG), online map services (inc. WMTS, TMS, XYZ, OSM-compatible services), and offline vector layers (inc. GeoPackage, Shapefile, File Geodatabase, GPX, KML).

Record locations as tracks and waypoints. Create and update custom layers and attributes. Style (symbology) of vector layers is highly customisable.

Bit Map was the first iOS app to provide navigation with arbitrary user-supplied maps in 2009.

Map image files need not be georeferenced before importing, as Bit Map includes 4 methods to georeference map images within the app.

Bit Map is built on a true GIS foundation and can manage data in hundreds of different coordinate systems, projections and geographic datums. Layers with different projections can be displayed simultaneously in the same map.

Limitations of the 'Lite' version are listed at:


Do not use Bit Map while operating a motor vehicle, other vehicle, machinery or in any potentially dangerous situation. Do not rely on Bit Map, or on the accuracy of data presented by Bit Map, for any purpose in which inaccuracies or any app behaviour could cause danger, loss, damage or problems of any kind to the user or to any third party.

Users are responsible for abiding by the copyright and license terms of any data, maps and services that they import, configure or use in Bit Map.

Son of a Beach ,

So many map sources in one app!

So cool to be able to mix and match various online layers from different sources, plus my own offline layers.

Georeferencing is so simple with the map matching method. A little more tricky with the GCPs method.
