CSAPI Demo Feedback at OGC 134th Member Meeting

[Sam-Bolling]

Welcome OGC CSAPI Friends and Stakeholders,

Thank you for attending the CSAPI Explorer demonstration during the 134th OGC Member Meeting. This discussion thread is intended to serve as an open, public feedback forum for the demo application. Whether you are a standards architect, implementer, product owner, or researcher, your perspective is extremely valuable.

🔎 What is CSAPI Explorer?
CSAPI Explorer is a lightweight client application designed to explore OGC API - Connected Systems (OGC CSAPI) compliant servers based on the published here https://www.ogc.org/standards/ogc-api-connected-systems/. The GitHub for the CSAPI Explorer webapp is here https://github.com/OS4CSAPI/ogc-csapi-explorer and it is largely based on the OGC CSAPI Typescript Client Library here https://github.com/OS4CSAPI/ogc-client (currently under review for contribution to the Camp-To-Camp OGC Client library camptocamp/ogc-client#136). To be added to the growing https://github.com/[OS4CSAPI](https://github.com/OS4CSAPI), please @Sam-Bolling in a comment.

The OGC API - Connected Systems standard enables client and server applications to connect all systems on or around the Earth into a common 4D framework for discovery, accessing, processing, reasoning, visualization, tasking, and action for all manners of systems (e.g., sensors, things, robots, drones, satellites, control systems, devices, and all manners of platforms across space, air, land, sea, cyber, and electro-magnetic spectrum).

🧪 Try the Demo Yourself

1. Visit the Demo URL: https://ogc-csapi-explorer.pages.dev/
2. Enter the Guest Credentials
3. Play around - that's it! No installation is required. Simply log in and begin exploring.

💬 How to Provide Feedback

After trying the demo, please:

1. Select a poll option below that best reflects your overall impression.
2. Leave a comment describing:
   • What worked well
   • What was confusing or unclear
   • Missing functionality you would expect
   • Suggestions for improvement
   • Alignment (or misalignment) with your CSAPI expectations

All constructive feedback is welcome — technical, UX, architectural, or conceptual.

🎯 Focus Areas of Interest

We are especially interested in feedback related to:
• Usability for first-time CSAPI consumers
• Anything relating to OGC APIs and Formats and the demo
• Support for real-world operational modeling use cases

Thank you for helping strengthen the OGC CSAPI ecosystem through practical experimentation and open collaboration.

We look forward to your insights.

Respectfully
@Sam-Bolling

Great work @Sam-Bolling! 👏🏽 It is nice to see the CSAPI ecosystem taking shape

I tried the server: https://os4csapi-osh.duckdns.org/sensorhub/api with the credentials you supplied and I can see the Landing Page, but it seems that the Systems, Datastreams and Observation endpoints are protected with different credentials. Is that on purpose?

If you don' t mind sharing those, would love to test your server in the QGIS plugin (:

[Sam-Bolling]

Greetings, @doublebyte1 and thank you for the kind words, it is a very exciting time! I didn't realize the landing page was returning internal URLs (http://...:8181). I've added proxyBaseUrl to the server config, so all API links now resolve correctly over HTTPS. It should work with your credentials now when you try it again. I would love to hear the results of your testing and see screenshots!

Sam

Thank You @Sam-Bolling ! It works perfectly now 👍🏽

Hi team,
I came across the OGC 134th Member Meeting CSAPI demo online and
wanted to share what I built on top of it.

Using Python in Google Colab, I built a full end-to-end pipeline:

1. Auto-discovery — queried the OSH server to find all 26 datastreams
   and identify LOB, SSL, SST, Health and SENREP channels

2. Live map — used Folium to plot UAS positions, sensor nodes, Lines
   of Bearing and SENREPs on an interactive map, auto-refreshing
   every 10 seconds

3. CSV logging — captured all UAS track fixes, LOB readings and
   SENREPs to CSV files in real time

4. ML anomaly detection — ran Isolation Forest on the UAS track to
   automatically flag anomalous fixes (sudden speed spikes,
   direction changes, low sensor contribution)

5. Trajectory prediction — used linear extrapolation on the last 5
   fixes to predict the next UAS position

6. Intelligence dashboard — built a 6-panel Matplotlib dashboard
   showing the flight track, bearing over time, uncertainty,
   speed distribution and anomaly scores

The pipeline tracked 30 UAS fixes across all 3 AZ-MA sensor nodes,
detected 5 anomalies and predicted trajectory in real time.

Happy to share the Colab notebook if useful for future demos or
onboarding new users to the API!

@nsnarayanam this is incredible, thank you for sharing! I would like to add a page to the demo client based on the work in your notebook, may I have your permission to do so?

Respectfully,
Sam

[nsnarayanam]

Dear Mr.Sam Bolling, Thank you — I appreciate that. Yes, you’re welcome to add a page to the demo client based on the work in the notebook. Please feel free to proceed, and if possible, kindly acknowledge the contribution or reference the source where appropriate. I’d also be happy to review or discuss the implementation if that helps. Looking forward to seeing how you integrate it. BR, Narasimha Sharma.

Greetings @doublebyte1 and @nsnarayanam, I have updated the demo with stories about your work with the demo here https://ogc-csapi-explorer.pages.dev/community and added a new UAS Analytics page inspired by @nsnarayanam's work here https://ogc-csapi-explorer.pages.dev/analytics. Thank you for your interest, feedback, and insights!

Respectfully,
Sam

Hi Sam, That looks fantastic! Thanks for the quick integration and for the clear acknowledgement. BR, Narasimha Sharma.
