Bit Map provides mapping and navigation with offline maps (inc. JPEG, TIFF, PNG), online vector or raster map services (inc. WFS, 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 can even publish your map layers to a Web Map and automatically keep them in sync with the web map! 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.
