History

#1 Updated by David Eads about 8 years ago

  • Target version changed from v1.1 (Sept 2011 project review) to v1.3 (JTechs - Jan 2012)

Crossing paths is basically impossible to fix in OpenLayers, which does not offer collision detection and inconsistent APIs across rendering systems (canvas, svg, and vml renderers are all underpowered compared to modern libraries).

Some combination of a leaner client mapping library like Leaftlet or Modest Maps along with a dedicated tile server, and Wax for some or all interactivity is the long term solution.

#2 Updated by David Eads about 8 years ago

One follow-up on the last comment (thinking out loud here): A "geo plugin" for the E-Center Network system is an important use case to consider when developing the 2.0 architecture data retrieval architecture. Generating from and injecting GeoJSON into DRS results can significantly simplify mapping if implemented wisely.

#3 Updated by David Eads about 8 years ago

  • Target version changed from v1.3 (JTechs - Jan 2012) to v2.0-alpha2 (JTechs - Jan 2012)

#4 Updated by Maxim Grigoriev over 7 years ago

  • Priority changed from Normal to Low
  • Target version changed from v2.0-alpha2 (JTechs - Jan 2012) to Year 3 milestone - July-Sep 2012

If E-Center continues with OpenLayer, this should probably be rejected unless feature collision detection in OL is improved. If Leaflet or another, more flexible, mapping solution is used, fixing this problem may become more feasible.
