Welcome to Developer Track Sessions at OGC Member Meetings! - March 2021

[ghobona]

👋 Welcome!

We’re using Discussions as a place to connect with other participants of Developer Track Sessions at OGC Member Meetings. We hope that you:

• Ask questions you’re wondering about.
• Share ideas.
• Engage with other developers in the community.
• Welcome others and are open-minded. Remember that this is a community we
  build together 💪.
• Abide by the OGC Principles of Conduct

To get started, comment below with an introduction of yourself and tell us about what you do with this community.

[chris-little]

@ghobona Thank you for setting this up. I was never able to use Gitter, as it never made it through our firewalls and security policies.

I am Chris Little, Chair of the Environmental Data Retrieval (EDR) API Standard WG, where "Environmental" means anything with spatiotemporal coordinates! I hope attendees will try out the API, which, fingers crossed, touch wood, and any other irrational beliefs that might help, will become a full OGC standard in a few weeks. Though there will be some editorial tidying up to do.

[ghobona]

@chris-little Welcome!

[skyNacho]

I am Ignacio "Nacho" Correas, working for Skymantics and with main interests in routing and AI (sometimes I can even combine both interests!). At Skymantics we have a working alpha of a general-purpose OGC-compliant API that we tested in a few pilots and testbeds. It currently implements the draft APIs Routes and 3D GeoVolumes. Prior to my engagement with Skymantics and OGC I founded and led the business and technical development of Zentyal, an open source alternative to Windows Server, bringing Microsoft's protocols to the Linux world.

Last year I heard of pygeoapi and since then I have been very curious to learn more about it but never found the time. It would make a lot of sense to adopt it and contribute to its development instead of continuing re-inventing the wheel with our own little project.

We are going to test new API concepts during TB17 and I was planning to try pygeoapi, so this developer track couldn't be better timed.

[tomkralidis]

Hi all: I'm Tom Kralidis, working with the Meteorological Service of Canada. I'm a longtime contributor to OGC standards and FOSS4G software (in particular Python and Go). Currently, I'm co-chair of the OGC API - Records Standards Working Group and also contribute to OGC API - Coverages and OGC Environmental Data Retrieval API standards.

My goal is lowering the barrier to implementation of OGC standards implementation for weather/climate/water communities (WMO), and anyone else.

Thanks and kudos to OGC for setting up a Developer Track; I'm excited to work with everyone in this space.

[serich]

I'm an OGC staff member managing Testbed-17. If interoperable running code wins (paraphrasing the IETF), then this must be where all the winners hang out. Hope you don't mind me hanging out with you.

[nilshempelmann]

Joining the introduction round :-).
New staff at OGC but dealing with OGC Innovations and Standards since a while. Basically working in context of climate data domain. You can find some work here https://github.com/bird-house

[StephanSiemen]

Hi all! Stephan Siemen from ECMWF here. Looking forward to the session today! :-)

[pvgenuchten]

hi, paul van genuchten, geocat, i'm presenting the tutorial on ogc-api records in pygeoapi with tom this afternoon. pygeoapi is an interesting lean technology to experiment with ogc api's. i'm also implementing an ogc-api records client in qgis and a server implementation in geonetwork

[bpross-52n]

Hi, I am Benjamin, chair of the OGC API - Processes Standards Working Group (SWG) and editor of the OGC API - Processes - Part 1: Core standard.

[kcski]

Hi I am active in the CDB community. I am working in the modeling and simulation community.
Have experience in python.

[aarathimuppalla]

Hi everyone. I am Aarathi, working as a scientist in National Remote Sensing Centre, Indian Space Research Organization.
Looking forward for today's developer track.

[AndrewRadburn]

Hi, I'm Andy Radburn working as a Data Scientist at Ordnance Survey. Looking forward to building something in Python.

[ShaneMill1]

Hi all, I am Shane Mill from NOAA. I contribute to the Environmental Data Retrieval SWG and am an early implementer of the EDR-API

[joanma747]

Hi, I'm Joan Masó from UAB-CREAF. I'm the editor of the Tile Matrix Set standard and the OGC API Tiles drafts with Jerome St-Louis. I will try to participate as developers in future editions of this track. Today I'll observe.

[iandruska-ibl]

Hi, I am Igor Andruska working as a software developer at IBL Software Engineering. I have been a member of the EDR SWG for the past year. I am also implementing an EDR server.

[iandruska-ibl]

Some EDR query examples to start with are available at https://github.com/opengeospatial/ogcapi-environmental-data-retrieval/blob/master/implementations.md#ibl-software-engineering

[NazihFino]

Hi all! Nazih Fino. Global Nomad GIS Services, Looking forward to inspiring and productive sessions today!

For those interested in the pygeoapi edr-api implementation: https://docs.pygeoapi.io/en/latest/data-publishing/ogcapi-edr.html

[ShaneMill1]

The National Weather Service's implementation is located here: http://data-api-c.mdl.nws.noaa.gov/OGC-EDR-API.

Just want to make a note that the URL will be available publicly for today only. As soon as our on premise system is back up and running, you will be able to access our implementation 24/7 at https://data-api.mdl.nws.noaa.gov/EDR-API.

Thank you all for listening to the demo/tutorial and please reach out to me here or at [email protected] if you have any questions!

[francbartoli]

I'm Francesco Bartoli from Geobeyond, part of the pygeoapi dev team. I present the tutorial about Retrieving vector tiles from OGC API - Tiles implementations using pygeoapi

[ghobona]

When installing pygeoapi following the steps on the pygeoapi homepage, if you run into the following errors, here is how I solved the issues.

Please note that I was installing it into an Ubuntu 18.04.1 instance.

---

When running this command pip3 install -r requirements.txt

I ran into error:

ERROR: Cython.Build.cythonize not found. Cython is required to build pyproj

The issue was solved by installing Cython

pip3 install Cython --install-option="--no-cython-compile"

Then had to upgrade pip

python3 -m pip install -U pip

---

I was then able to run:

pip3 install -r requirements.txt

However, I ran into the error:

ImportError: No module named setuptools

The issue was solved by running this:

sudo python3 setup.py install

---

Then when I ran, pygeoapi generate-openapi-document -c $PYGEOAPI_CONFIG > $PYGEOAPI_OPENAPI

However, I encountered this error:

"ModuleNotFoundError: No module named 'xarray'"

The issue was solved by running this command:

pip install xarray

---

Then retried pygeoapi generate-openapi-document -c $PYGEOAPI_CONFIG > $PYGEOAPI_OPENAPI

But ran into an error that netcdf4-python or scipy had to be installed.

The issue was solved by running these commands:

python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

pip install netcdf4

pip install tinydb

---

I was then able to complete the installation with these commands.

pygeoapi generate-openapi-document -c $PYGEOAPI_CONFIG > $PYGEOAPI_OPENAPI

pygeoapi serve

I now have a running instance of pygeoapi!

[francbartoli]

Great @ghobona! For the different providers like xarray for example there is a convenient requirements-provider.txt file to run

pip install -r requirements-provider.txt

in one shot.
