Apr 23	comment	Averaging satellite data with missing values (using Python) About 3-4 months worth (using daily files). My plan is to just use an average value for the entire sampling period, or perhaps for duration of each individual cruise performed within the sampling period.

Apr 23	comment	Averaging satellite data with missing values (using Python) So I would create a cummulative mask from the datasets that I am averaging together, then apply that when doing the calculations? If I am missing values for just one day, then I would end up with a lot of missing data. Is it possible to weight it based on number of days where data is present, or something?

Feb 28	comment	What's the best projection for rasterization of random latitude and longitude data in the northern Atlantic? GDAL's grid_data offers only inverse distance to a power, moving average, and the nearest neighbor algorithms.
Feb 28	comment	What's the best projection for rasterization of random latitude and longitude data in the northern Atlantic? Just saw that I didn't select an answer, my apologies. As for your last comment whuber, would you suggest any particular statistical method(s) for interpolation?

Feb 13	comment	What's the best projection for rasterization of random latitude and longitude data in the northern Atlantic? This is excellent. Thanks whuber. I now realize I should have rather said that I am attempting to interpolate the sighting effort data, which I think maybe should be handled differently - kind of like a catch per unit effort (CPUE) value. The plan is to ultimately make ESRI ACII grid files of my environmental covarients and sighting (i.e. presence) data to run in the MaxEnt model. I hope to use the effort in determining my study area (what data to include for the model).

Dec 16	comment	Why do I get “Failed to transform” when reprojecting from WGS84 to Google Mercator? Thanks underdark, it appears the Natural Earth quickstart kit contains the same files, so I suppose this error has developed with the new release of Natural Earth's data.

Dec 15	comment	Why do I get “Failed to transform” when reprojecting from WGS84 to Google Mercator? In double checking my method here, it looks like the projection I attempted to save to was in fact WGS 84 (EPSG:3395) and Google's Mercator is EPSG:900913. Is this still the issue, and where might I check the extent of each projection?
Dec 15	comment	Why do I get “Failed to transform” when reprojecting from WGS84 to Google Mercator? Hmmm... I have found the above mentioned dataset (also with an xMax,yMax 180,83.6341), but not the 10m_admin_0_map_units data that is mentioned in the tutorial. I thought that the ne must just stand for Natural Earth and was left off of the name of the file in the tutorial.

Dec 15	comment	Why do I get “Failed to transform” when reprojecting from WGS84 to Google Mercator? I just gave it another shot with the ne_10m_admin_0_map_units dataset, and it is giving me the same error. I have updated the error in my post to reflect the correct dataset.
Dec 15	comment	Why do I get “Failed to transform” when reprojecting from WGS84 to Google Mercator? Great to know. So 'Google Mercator' is the same as WGS 84 Mercator then? Thanks!
