License:	proprietary (free, payed)
Platform:	android
Online/Offline map viewer (area downloader or tile cache), support slippy (non-free too) and vector maps (lots of formats), guiding, routing and basic navigation (online only), track recording with detailed POIs (including photos) and altitude correction, extensive geocaching support

This tool may result in heavy traffic for the OSM tile servers if used improperly, and this mode is likely to be blocked (see Blocked applications for an explanation). This software has possibility to use offline/cached maps from OSM which doesn't hurt performance, please see below ("Alternative OSM map access").

Locus ([1]) offers many useful features such as:

• Online maps (browsing and downloading)
• Offline maps
• Navigation (online calculation tracks)
• Vector maps
• WMS service
• Track recorder
• Integration of Google My Maps (reading and editing)
• Geocaching
• Parking
• Weather service
• Point of interest
• POI alert
• Search (by adress, coordinates, contact)
• Custom screen (created by community)
• Integration of GPSies, Breadcrumbs, Street View and other
• API for developers

Alternative OSM map access

Due to the popularity of Locus and the greatness of OSM there were high demand for OSM generated tiles which made official servers to choke and die. Since excessive access isn't desired Locus was blocked from using tile servers altogether.

The author of Locus created the possibility for vector maps well before the block (and repeatedly advised users not to use OSM tile servers), and the vector map support was streamlined so it is possibly one of the most useful mode available. It is available in both free and pro version.

Vector OSM maps available for free in several sources but due to their size it is often problematic to host them. One possible place is http://www.vectormaps4locus.eu/ which uses uploaded.to service.

Another way is to generate them from recent OSM dumps and simply move the .map file into the directory Locus/VectorMaps/.

Generating OSM vector maps

• You need a recent version of Osmosis (tested with v0.39)
• Get your preferred map from the kindly donated server of GeoFabrik, like http://download.geofabrik.de/osm/europe/hungary.osm.pbf
• Convert the file with osmosis:
  • osmosis --read-pbf "hungary.osm.pbf" --mapfile-writer file="hungary.osm.map"

• Binary format dumps contain the bounding box (unlike XML dumps, don't ask why), but you can still restrict it further by using the bbox= parameter, like for Hungary bbox=45.67,15.81,48.64,23.1
  • osmosis --read-pbf "hungary.osm.pbf" --mapfile-writer file="hungary.osm.map" bbox=45.67,15.81,48.64,23.1
