[Playerstage-developers] Proposal to replace vector map interface

[Toby C. <tob...@in...>]

Hi,
The vector map interface is fairly limited with only simple line segments
supported. I am proposing to replace this with support for for the Open
Geospatial Consortium simple features
(http://en.wikipedia.org/wiki/Simple_Features) This will allow the
representation of more complex geometries as single features allowing
sensible grouping. Each feature could also be given an ID in parallel
allowing extra information to be requested about it seperately. The OGC also
sepcifies a standard binary structure to represent a feature (well know
binary or WKB) as well as a text standard (well known text or WKT). These
standards are used fairly widely in the open source GIS community with
support in postgis (the geospatial extensions for postgres). My feeling is
that there is very limited use of the vector functions of the map interface
so we should be able to just change the interface without any issues.

The simple feature set described by OGC also maps fairly easily between
other formats such as shapefiles and KML (google earth)

Any comments on the proposal?

Toby
