comment Simplify geometries but keep them contiguous
Thank you. The second method looks promising to me. Right now I have been given a simplified source, which solves my problem for the moment. I shall probably return to this later.

Thanks. I did try this snap to grid method. Either the grid was too large, and shapes became rectangles, or there were still gaps.

comment Simplify geometries but keep them contiguous
thanks @elrobis. I had seen other similar posts (that were not postgis). all sounds a bit frightening, as it seems to lose the connection between the geometry and its data, only to reconnect them at the end using ST_PointOnSurface (what guarantee is there that that point will be in both shapes, when we just changed one of their shapes?).

@JohnBarça Just to clarify, did you mean to say ST_SimplifyPreserveTopology (and does what you say apply to ST_Simplify as well as ST_SimplifyPreserveTopology)?

comment How to stop/disable an openlayers 3 animation?
I think a custom pan function, that tracked the real location and was cancelable might be the way to go, but I am not sure if returning "false" is sufficient to cancel the animation.

comment How to stop/disable an openlayers 3 animation?
I think the animation panning is independent of the actual map's center (which is set immediately after setCenter), so if you did manage to stop mid animation, you would have to work out the maps physical pan/zoom and set those values.

I can't see any documented way of doing this (the feature is only makred as experimental after all). I would love to stop the current animation on any map click.

comment British National Grid to KML results in offset polygons
How did you work around it? Did you programmatically add/subtract 4 metres from every point? Or did the conversion to GeoJSON just work better?
