How we do it
SLIDE 11
How we do it
Generic approach how to generate delta maps 1. Generate complete map ith our primities before and after including all possibl changed primities 2. Compare complete maps and generate delta map 3. Split delta map b regions and sere them
OsmAnd.net
SLIDE 12
How we do it
Approach how to store and serve 1. Generating maps eer 10 minutes ill produce 240 delta maps daily and 1000 delta maps monthly 2. Eer missing delta map could cause map errors Solution:
- Group delta maps b day and b month ecl last da
- Clients keep maimum 5-7 maps per month per region

Overpass query to retrieve complete data
[timeout:3600][maxsize:2000000000] [date:\"$END_DATE\"]; or [date:\"$START_DATE\"]; ( node(changed:\"$START_DATE\",\"$END_DATE\"); way(changed:\"$START_DATE\",\"$END_DATE\"); relation(changed:\"$START_DATE\",\"$END_DATE\"); )->.a; (way(bn.a);.a) ->.a; // retrieve all ways for all nodes (relation(bn.a);.a) ->.a; // retrieve all relations for all nodes (relation(bw.a);.a) ->.a; // retrieve all relations for all ways (way(r.a);.a) ->.a; // retrieve all members for all relations (node(w.a);.a) ->.a; // retrieve all nodes for all ways .a out geom meta;

Future of data
SLIDE 19
Future of data
- All projects around OpenStreet)ap are built on open data
- OsmAnd uses OpenStreetMap, Wikipedia, Wikivoyage
- Each portion of data deseres on format
- Each application deseres on deried format

Future of data
- Each format has same lifeccle
○ Conert ○ Distribute ○ Update
- Etra GEO Features
○ Partition b countries ○ Incremental and distributed donloads

- Possible affected formats / application
○ OBF / OsmAnd ○ Oerpass / Oerpass Quer Engine ○ Postgis / )apnik ○ Oerpass / Achai ○ Postgis osm2pgsql / OS) Validation tool ○ TIFF + DE) data / An router tool ○ Wikimedia data / An end user application

Technology proposal OsmAnd.net
Can e build an application network that ill support:
- Registr of data ith License / oner information
- Aka torrent distributed donloads
- Partition data b geo bbo
- Supports data streaming and delta updates
- Hae an eas to use serer and desktop client
