comment ogr2ogr: don't import properties on each feature?
Thanks. I did look at the manual page, but I obviously didn't read all the small print carefully enough, because I didn't see that!

Print Composer in QGis actually works pretty well.

Thanks for this answer, but I just tried it and got a solid yellow block with x and y axes covering the latitude and longitude ranges... not what I was looking for! Thanks anyway.

(I just want a PNG image, not a raster. Is there a difference?)

@Spacedman brilliant. 1000x1000 is fine (I'll play around and see what looks best). The coordinate system is WGS84.

Thanks. Unfortunately the QGis option only seems to export a tiny image - I'm looking for a big one that I can print... I might try this option: anitagraser.com/2010/11/30/…

Thanks for this. Yes, the time field can be ignored, I just want an image of all the points. Sounds like gdal_rasterize is the way to go?

@Spacedman - I was envisaging a black pixel wherever there was a point, and transparency otherwise. And I don't care about coincident points, one pixel for those is fine.

@Luke thanks for following up - I've added a sample of the data. (The Time field can safely be ignored.)

@Mapperz I'm a professional developer but have no access to GIS software (except what I can install for free!). Ideally I would prefer to use something command-line, I have GDAL installed already.
