Since my laptop is on the brink, I’ve been shifting my data processing from my Sun VBox over to the arm processor Sheeva Plugin (aka wall-wart). Previously, I’ve used this mostly as a file server front end, connected to a “My Book.” But I’ve been able to get most of my dev cycle working on it. “R”, “gdal-bin”, “open-java” are all running – although it takes about 2 minutes for the jvm to launch – suitable for scripting but not great for development.
Just listen to the music of the traffic in the city,
Quick dip back in the gene pool to grab some GPW population data. GPW data was downloaded as 2.5′ resolution BIL files and converted to GeoTiffs with gdal_translate. These were read by the GeoTiff data reader and grid values extracted for each GHCN station. Some GHCN station names have been changed to
protect the innocent remove commas.
This is a CSV file with the 5 year population data from GPW (and a rural/urban flag) for each GHCN station.
This is a CSV file with the 5 year population density data from GPW (and a rural/urban flag) for each GHCN station.
Linger on the sidewalks where the neon signs are pretty.
Just listen to the rhythm of the gentle bossa-nova,
You’ll be dancing with them, too, before the night is over
Next up, per requests, probably process some more sea based data.
And still working through the automated build of the GSOD data
A quick note on the naming convention. I’m not very consistent with this, but more or less as follows …
my = my hands were the last on the data
ghcn = ghcn v2 format for inv and mean, or ghcn station meta data
xxx[.xxx] = other data source being used
[inv|mean] = type of ghcn data set
[txt|csv] = fixed field or csv
[gz] = gzip
