ulmo news.

[Dharhas Pothina]

Hi All,

I've transitioned from TWDB to a new position at the U.S. Army Corps of Engineers. Andy has also transitioned to a new position within the TWDB. 

So what does this mean for ulmo? Well, the good news is I've managed to convince folks at my new work place that continuing to contribute to ulmo and keeping it open source is a Good Idea (tm). In the near future, I'm going to work on adding various raster datasets (elevation, landcover etc) to ulmo. Andy will still be around, but his new position may not involve quite the type datasets we pull with ulmo. 

As part of this transition, we have moved the development site from https://github.com/twdb/ulmo to https://github.com/ulmo-dev/ulmo

If anyone is particularly interested in raster datasets, let me know and we can coordinate.

Thanks for the update, Dharhas. And glad to hear about the sustained effort. Raster data handling sounds like a bit of a stretch for ulmo, but good luck! BTW, I haven't used raterio yet, but you should check it out:

Well I originally was hoping to use owslib to pull from wcs services, but both wcs services and clients seem horribly broken, it looks like it never got as popular as wms and it shows. Also, most other 'get raster' tools seem to be heavily GUI oriented and I need something programmatic. So I'm going to build some tools that can navigate the USGS EROS and some other systems to get GeoTiff files given a bounding box. I plan to use rasterio (I found it while googling yesterday) to do some basic raster mosaic/clipping to get the region that is requested. So in that sense it should fit the ulmo design philosophy of solving the transport problem and giving you something easy to work with.

Makes sense.

Regarding WCS, yeah, I'm still not persuaded it's made any meaningful inroads, compared to WMS, WFS, etc. And when it comes to 3D or 4D grids, people working with such data in the earth sciences are usually using opendap/opendap-cf instead.

Have fun,
