OSM sketch vs OpenMapTiles

For OpenStreetMap(OSM) mapping, drawing your memo on paper printed the OSM map is good solution. You can describe on the paper anything e.g. Line, words, arrow, symbol and illustration. "OSM sketch" realize such paper mapping on iPhone. You can draw on OSM map anything you want to memo anywhere, anytime without printing beforehand. Operation is easy and optimized for small screen. Multi touch operation ,scroll and zoom, can be executed also during "drawing mode" so you can pull new canvas out quickly. To display current location and zoom in/out map support your mapping and these function are difficult for paper. The drawn line exchange into GPX file and upload to your OSM account page. You can open the GPX file by PC OSM editor(iD, Potlatch2 and JOSM) and edit OSM data based on your lines when you return your home.

Maps under your control! Get the source code and detailed OpenStreetMap vector tiles saved in MBTiles format - usable offline, with your GPS location. The OpenMapTiles team (https://openmaptiles.org/) made this app as a starter for your app development! Try offline map functionality by downloading a street map for the whole planet, country or city of your choice. The map data can also be embedded and distributed together with your app! The complete source code of this mobile application is available for re-branding and customization - just add your business logic and extra mapping functionality with open-source Mapbox SDK. By using OpenMapTiles.org project, you can design and style the maps according to your needs, host the map tiles on your servers (even on a standard Apache web hosting), create optimised map extracts for offline use and unlimited redistribution. You can simply make your own independent maps for any place on a planet! Compatible raster tiles can be generated with MapTiler software (http://www.maptiler.com/). For more advanced editing functionality, drawing of the features, attaching photos and collecting field data we have developed GeoEditor mobile app (https://www.maptiler.com/mobile/). It is available including source code too! We offer support, consulting and contracted development of mobile applications, including geodata processing and creating of vector and raster map tiles in custom coordinate systems.
