Hey Jeff, It's somewhere between the two - the original satellite swath is converted to a regular 0.5 degree grid by truncating, binning, and averaging each point's lons and lats over the top of a 720 x 360 np.zeros array. the plotting still works fine for non ortho/ hemispherical projections,

I should perhaps of explained my code (included in top post) a little better, the values in my attached file aren't on a regular grid to start with, I do a little bit of juggling as follows to get them into a regular grid: I'm firstly setting up my 2D grid of 0.5 degree lat lons, followed by

Jeff, this is great, works fine - many thanks for all your help over the last few days, it really is appreciated. I'm trying to build the case within my office for switching over to Basemap from IDL, ironing out niggles like this is really useful in this respect. All the best, Will. Jeff

Hi again Jeff et al... I've had a play around with the extra few lines of code - on paper this seems like it should solve the problems I'm experiencing. However, an error's being thrown up by the transform scalar function, as my lons and lats won't necessarily be increasing. The data I'm

Hi forum/ mailing list, When I plot in the orthographic projection I'm getting the large artefact shown below extending away from the north east of the globe. I'm not finding the same problem when plotting in a full globe projection so I'm presuming the problem is with the way I'm projecting

This is great Jeff, thanks for the help - I'll give it a try over the weekend (it's bank holiday here in the UK!) and get back to you, if I'm still having trouble I'll stick up the plotting data too... thanks again. Will Jeff Whitaker wrote: On 4/2/10 4:27 AM, Will Hewson wrote: Hi forum/
