 This then is a holding page for ideas on how to move //​Mapcraft//​ into a more dynamic, web based, environment. Navigation similar to //​GoogleMaps//​ would be good, with support for much larger maps stored in a database. This then is a holding page for ideas on how to move //​Mapcraft//​ into a more dynamic, web based, environment.

 +===== Implementation =====
 +
 +This supersedes the //Initial Ideas// section below. We have hex based tiles, with an assumed resolution of 1 tile = 5km. The map is divided into //sectors// - each 32x40 tiles in size. Dynamic resolution is based on the sector/​sub-sector etc.
 +
 +A sector is sized so that it fits nicely onto a single sheet of A4 paper. The back end also supports a caching mechanism to we read/write whole sectors at a time for hopefully better performance.

 +==== Sectors ====
 +
 +Maps will be organised into sectors if 32x40 hexes, in the same style as //​Traveller//​ star maps. Each sector consists of 16 (4x4) sub-sectors,​ each of 8x10 hexes. This latter fits nicely onto an A4 sheet of paper, hence the choice.
 +
 +Each hex represents an area 5km across.
 +
 +An entire sector can be represented by a single hex (0101). If no other hexes are defined in the database, then the entire sector is assumed to be the same as this hex.
 +
 +A sub-sector can be represented with a single hex in the same way. There is the possibility of falling back to sub-sub sectors (4x5 hexes).
 +
 +This saves space in the database in areas with little detail.
 +
 +===== Current Status =====
 +
 +Currently SVN has code which can display a basic map - things and paths aren't yet supported. There is a REST interface for this, which works nicely for getting tiled map images.
 +
 +  * REST interface to display maps.
 +  * Display Things (towns, cities etc)
 +  * Display map by named area. 
 +
 +There is also a utility for importing maps from the old XML files, which is being used for testing. How best to do actual editing has yet to be decided.
  
 +Support for the REST interface has been added into the Alfresco Yagsbook implementation,​ so that a Yagsbook encyclopedia can now reference these maps and embed them. Maps can currently be selected according to area, and the area is automatically scaled to a sensible size.
