    dont you have an example on the geopython workshop from bucharest, I recall that Jachym had a good example on his tutorial

    @tomkralidis
    does window take geographic coords though?

    Should only be

    @tomkralidis hope I understand correctly, slicing out a rectangle from a raster based on geo-coords? With CLI I would use gdal_translate, possibly there is a way via Python API.

    @tomkralidis
    thanks @justb4 and @jorgejesus. Use case is using rasterio for pygeoapi coverage implementation

    you need to convert the lat,lon coordinates into X.Y (have code somehwere for it) but the link above uses rasterio
    and is simpler
    (check the solution bellow)

    @tomkralidis
    thanks. Is it me or should the concept of clipping a raster by geographic coords be simpler?
    Just van den Broecke
    @justb4
    @tomkralidis from the docs found rasterio.windows.from_bounds.

    Happy new year!

    Thought I'd share some MovingPandas samples with you: http://exploration.movingpandas.org

    @just I did pixel indexing which worked but from_bounds seems easier. Thanks.

    @anitagraser Nice :)

    Hi @all - not sure where to post, I've a question related to the use of pydap from inside a docker-compose environment and I thought this channel is followed by very knowledgiable people who my be able to help me.
    My problem is:
    • given a docker-compose environment with 3 containers running 3 services apache , pydap, jupyter. A simple csv file is served via both apache and via pydap
      From outside the docker environment, the file is available using the host IP address without problems (using both apache and pydap)
      The problem arise when I try to access the csv data from inside the jupyter service, which runs from inside the same docker network.
    from the notebook I can access the data served via hyrax or via apache using the service name, but the same request fails when attemting to access the data served via pydap

    @epifanio
    I prepared the test , it is a basic repository with 4 docker machine:

    • Apache2
    • Pydap
    • Hyrax
    • Jupyter Notebook

    It is available here: https://github.com/epifanio/Docker-Networking

    @epifanio
    essentially, I put some data in a volume and I made this data available in:

    and everything works as expected

    I then use a jupyter container (on the same docker network) to access the same data but using the docker-machine-name defined in the docker-compose
    using the pydap client I can access the data served by hyrax, or I can use wget to fetch the data served via apache ... but when trying to attemt to fetch the data served by pydap I got an error ...

    this notebook shows the issue:

    https://nbviewer.jupyter.org/github/epifanio/Docker-Networking/blob/18c81e30312f9db3da305c677a7884a0d670c0db/volumes/jupyter/notebooks/test.ipynb

    epifanio
    @epifanio
    it seems that pydap server side doesn't allow the use of the service hostname used internally by docker
    have you experienced something similar, do you have any clue on what is wrong?

    From the GeoPython Conf organization: 
    Martin Christen, [26 jul. 2020 21:27:49]:
July 27 would have been the date for GeoPython 2020, it is really sad it didn't happen.

But I have interesting news

There will be a "mini" GeoPython 2020 online edition, September 21-22, 2020 (together with Python Machine Learning Conference). Call for proposals is open until August 17. http://2020.geopython.net/  - More information will follow!
    So see http://2020.geopython.net/

    @justb4 do we have contact info for the conference organizers?
    or is there anyone from the organizers here?
    Just van den Broecke
    @justb4
    @kalxas not sure what you mean: we have submitted a pygeoapi abstract yesterday (see pygeoapi gitter), the main contact for the conf is Martin Christen, Professor FHNW Basel. He is not in this group but easy to find e.g. linkedin. There is also an open Telegram group for the conf: see http://2020.geopython.net/ (Social Media bottom of page).

    Hi everyone, I am new to geopy and python itself. I'm not sure if this is the right forum, and I would be grateful if any of you could point me to the right place for my queries. I know that geopy uses the great circle distance to calculate the distance between two coordinates but I read somewhere that this formula isn't very accurate for short distances. I have a set of stations which can get as close as 5 kilometers from each other, I wanted to know if using geopy.distance is a good idea or if there are more accurate tools for such short distances.
    Just van den Broecke
    @justb4
    @DJMO3 never heard of geopy but it uses geographiclib . Make your question more specific: 1) are your coordinates lon/lat in WGS84? 2) what level accuracy you want to achieve (percent). Great-circle can be up to 0.5%. Better is to use geodesic distance, supported by geopy. Many geo-folks use proj but looks like your case can be covered with geopy. Their main comm-channel is StackOverflow.
    DJMO3
    @DJMO3
    Thank you for your time. I am using the WGS84 lat/long format but still need some more research and testing to determine the level of accuracy. I will be looking further into the geodesic and proj library too.

    Hi all: FYI Joint OSGeo/OGC/ASF sprint 17-19 February 2021:

    This is a great opportunity for Geopython projects to converge and collaborate w/ both OGC and Apache. pycsw/pygeoapi/OWSLib projects will be on hand, and it will be great to see others.

    The sprint is online/virtual and open to all. See you there!

    Hi all: I just realized our Geopython projects presentation (http://geopython.github.io/presentation/) had an import geopython statement.

    I’ve since created a first pass vanity package at https://pypi.org/project/geopython/ (source code https://github.com/geopython/geopython), which one can install and run :). As always, contributions welcome.

    PSA: pyyaml vulnerability: https://nvd.nist.gov/vuln/detail/CVE-2020-1747

    Hi!

    We are building the FOSS4G schedule and we noticed there are a few proposals that are "Live Coding". A developer live codes around some topic (like how to do maps with X and Y) and accepts requests/suggestions from the audience asking how to do stuff.

    Is someone brave enough here to want to do a session like this around one of your geopython projects? I am thinking showing how to work with pyWPS or the pyGeoAPI could be pretty interesting :) That could help attracting more members to the communities once they see the project in action.

    It's not a workshop in the sense that you don't care if your audience can compile in their laptops or not. It is more like a show in which you as developers demo the project.
    We are open to more projects, not necessarily python too.

    @kalxas
    Hi Maria, this is an interesting idea, we usually submit a geopython workshop (we did submit it again this time)
    María Arias de Reyna
    @Delawen
    And would you be willing to do both? (how was your workshop named? I see two)
    Ah, see it
    Or change the workshop for this?
    I think both are interesting
    Tom Kralidis
    @tomkralidis
    we have a geopython workshop submitted. I’m not sure about the others?
    “doing Geospatial with Python"
    María Arias de Reyna
    @Delawen
    Yes. Spoiler: it is on line to be accepted.
    But maybe you want to do both things? or prefer the live coding'
    ?
