Is Tom A. saying that extension arrays will enable Dask for GeoPandas? https://twitter.com/TomAugspurger/status/1088644514594533376?s=19
@anitagraser not directly. But with his recent work, it should become easier to do. But if you want to play with the geopandas / dask combo, I would still recommend looking at https://github.com/mrocklin/dask-geopandas
I can help with setting it up if you want
That experimental package also implements a parallel spatial join, has some functionality to partition the dataset by regions, and already parallelizes all the spatial operations and predicates.
@anitagraser I'll be happy to assist you folks. AlphaSense gas sensors (like above) are good but need quite some extra electronics and calibration, even per-sensor, to get results R2 ~ 0.9, like above. For PM (finedust) there is the Luftdaten project, was at a Meetup this week, amazing fast-growing, low-entry, activist/community project!, felt like when OSM once began: https://luftdaten.info/ and The Map: http://deutschland.maps.luftdaten.info, still coverage to be done in your country! Also Luftdaten sensors (SDS011 for PM10/2.5) have calibration issues. Possibly we Python folks can help out with our Scipy/Numpy/Pandas ANN MLV knowledge there. And if you want (Mikro)Python and LoRaWAN: https://twitter.com/justb4/status/1087740772210884608
Hi All. Really pleased to be part of this group. The growth in Python generally is amazing. I just looked at the stackoverflow trends and more questions are asked about Python now than are asked about Javascript (ok very different languages) but still. https://insights.stackoverflow.com/trends?tags=python%2Cjavascript
It looks (to me at least) that most of this growth seems to come from Pandas and Tensorflow. https://insights.stackoverflow.com/trends?tags=numpy%2Cpandas%2Cscikit-learn%2Ctensorflow
From West to East: Martin Is also organizer of the GeoPython conf: http://2019.geopython.net/
A Python package to read/write spatial data to a geopackage. https://github.com/achapkowski/pygeopackage
Pondering GeoPython conf: http://2019.geopython.net/ Basel, deadline CFP Feb 28. GeoHealthCheck and Stetl. But may collide with FOSS4G-NL, though latter not yet confirmed with LOC. Anyone else going to Basel?
hey all: PSA for thus year’s OSGeo Community Sprint in Minneapolis: https://wiki.osgeo.org/wiki/OSGeo_Community_Sprint_2019
I will be there and hope to see more geo Python folks!
@all hi @/all for the OSGeo Code Sprint in a couple of weeks I put up some items for various geopython projects we can work on: https://wiki.osgeo.org/wiki/OSGeo_Community_Sprint_2019#Project_Plans . Please feel free to add/update.
the dds was not generated with an encode error .. found in the apache log (running pydap as wsgi in apache)
I hacked a temporary fix adding an exception and asking pydap to decode using utf-8 instead of ascii
while ythis fixed the dds rendering
in a python client I can't load such dataset which returns the following error:
---------------------------------------------------------------------------

anyone knows it, or test it ?
.. since I am US-based, I notice the PANGEO project, and the requirements for that
@barryrowlingson definitely R sf Jupyter .. so there will be three Jupyter kernels at least, but you might imagine, disk space is an issue
Today/tomorrow is the GeoPython Conference 2019 in Basel. Actually two livestreams on YT: track1: https://www.youtube.com/watch?v=3KRYObqpMlk track2: https://www.youtube.com/watch?v=67C5jsmfE2s (will present GeoHealthCheck there 09:45 CEST)
@/all PSA:
at FOSS4G 2019 we delivered a 'Doing Geospatial in Python' workshop which was well attended. The workshop is on GitHub and folks can start at https://geopython.github.io/geopython-workshop/ and go from there (you need Docker and docker-compose). Any feedback, suggestions, improvements are appreciated!
In addition, we have a living Geopython presentation at http://geopython.github.io/presentation/ which can be used when describing some projects from the Geopython community (updates welcome).
