Évora is a UNESCO World Heritage Site and was chosen to be European Capital of Culture in 2027.
Here is a list of recommended hotels:
- The Noble House: https://thenoblehouse.pt/en/home
- ADC - Albergaria do Calvário - Boutique Hotel: https://adcevora.com/en/home
- Évora Hotel: https://www.evorahotel.pt/en/
- Vila Galé Évora: https://www.vilagale.com/en/hotels/alentejo/vila-gale-evora
When arriving in Portugal via airplane to Lisbon, you can reach Évora by public transport, using either train or express bus. In both cases you need to start by coming from the airport to the "Gare do Oriente" transportation hub. Either take a metro from Lisbon airport to the "Oriente" station (three stops from the airport) or take a taxi/uber/bolt (should be about 10 min.) and then either:
-
Board the "Intercidades(IC)" train bound for "Évora". The Journey from "Lisboa - Oriente" to "Évora" station is only about 1,5 hours, but we recommend you to check the train times in advance, as there are only a few trains per day - price is around 15 €.
-
Take an express bus to "Évora". Journey time is also around 1,5 hours and prices in the 5 - 10 € range. Some reliable operators:
If you prefer to drive, Évora is under 1,5 hours from Lisbon on the motorway.
Évora is also reachable from the Faro airport, in the south of Portugal, albeit a bit further, with journey times of about 3,5 hours by either train or bus.
The code sprint will be held on Western European Time (WET/UTC/GMT). You can check here the time in other locations.
This is the schedule for the main track. For the mentor stream, please check the detailed schedule here.

If you are coming to an OGC Code Sprint for the first time, you may be a little lost and confused about what you should do when you get there. That is why we will have an onboarding day, to help you get started in the OGC Community. In the discord server, you will find a section of called "mentoring", which contains multiple channels. On day 1 of the code sprint, we will feature a stream of tutorials, which will take place at the V:👥 [#Mentor Room].
On the first day of the code sprint, there will be a mentor stream onboarding session at the V:🎙 Mentor Room.
26th of February, 10:10 - 10:30 UTC - https://www.timeanddate.com/worldclock/meetingtime.html?iso=20240226&p1=224&p2=179&p3=16&p4=44&p5=240&p6=136&p7=133
If you would like to present a hands-on, entry level, tutorial, just add an entry bellow, following the same format. Please choose a time slot on day 1 (the 26th), that does not conflict with any of the scheduled events.
Apache Spatial Information System (SIS) is a Java library for building geospatial applications. Apache SIS supports a dozen of OGC/ISO standards, including ISO 19115 metadata, an advanced implementation of referencing services, and GeoTIFF. This tutorial will use a JavaFX application and JShell for showing what Apache SIS can do, together with code snippets giving entry points for using those features.

RISCO Web Maps is a generic browser-based 2D GIS data visualisation and editing solution oriented for responsiveness and mobile support.
On this workshop, we'll begin building / running a RISCO containerized solution (comprising PostGIS database with sample data, Golang feature server and FastAPI webapp using RISCO JS API) showing a Évora city explorer. Next, we'll add layers, change feature styles, configure info popups and map tips, etc.
If we have enough time, we will explore some edit functionality. At the end, with the help from JavaScript-minded people in the audience, we'll briefly discuss the addition of support for OGC API layers to RISCO JS API.
Please, follow this link to find workshop materials.

This is a mentored walk through of the entire process of getting your pygeoapi server up & running to serve vector data. We will ingest vector data into an elasticsearch index and leverage the modular architecture of pygeoapi and OGC API to publish it simultaneously as OGC API - Features and OGC API - Tiles. Then we are going to explore this dataset, by using a HTML/JS client, created with leaflet. At the end of this session, you should be able publish a vector dataset as tiles and features, and consume it using a web browser, QGIS or any other http client. The data and software used in this presentation are a result of the eMOTIONAL Cities project.

This tutorial will introduce the datacube concept, modelled through the joint OGC / ISO coverage standard. We look into the data structures for regular and irregular grids, see where space & time are defined, how the pixel semantics is encoded, and more. Further, we discuss operations and how services can be built on top of datacubes, which is a hot topic of discussion within OGC currently.
Sample services are available for experimenting, running the OGC WCS datacube reference implementation, rasdaman. All material will be made available, including links to further detail information as well as public sandboxes.
This session, led by the main coverage specification editor, is an excellent primer to learn about coverages as served by a variety of APIs addressed at this code sprint.

Stream leader: Krishna Lodha
Proposed schedule: 26th of February, 16:20 - 17:00 UTC - https://www.timeanddate.com/worldclock/meetingtime.html?iso=20240226&p1=224&p2=179&p3=16&p4=44&p5=240&p6=136&p7=133
Securing a modern API in an effective way is critical to prevent unauthorized access and ensure the privacy and integrity of data. In general, there are three common mechanisms that can be used for API security:
- API keys
- OAuth2/OpenID Connect
- JSON Web Tokens (JWT)
Each of these mechanisms provides a different level of security and flexibility, depending on the requirements of the API. Modern OGC APIs are agnostic and rely completely on the adoption of OpenAPI security schemes so the implementers can use the mechanism that perfectly fits with their requirements.
fastgeoapi is a new project designed to provide authentication and authorization on top of a vanilla pygeoapi. It uses pygeoapi as a python dependency in a FastAPI application aiming to offer, out-of-the-box, a secured infrastructure in the cloud for OGC APIs which is easily pluggable and developer-friendly. This tutorial gives a basic introduction to API security and describes some recipes to configure and protect a regular pygeoapi with open-source security tools in order to publish protected OGC APIs in a standard manner.
Technologies: pygeoapi, FastAPI, Keycloak, Open Policy Agent
Requirements: A basic understanding of authentication and authorization for APIs

Proposed schedule: 26th of February, 18:10 - 18:50 UTC - https://www.timeanddate.com/worldclock/meetingtime.html?iso=20240226&p1=224&p2=179&p3=16&p4=44&p5=240&p6=136&p7=133
This tutorial will cover how to manage, verify and publish metadata using GitHub as a management platform. Metadata files are managed as pygeometa MCF records, and GitHub Actions are used to verify, transform and publish notification messages to an MQTT broker.
From here, a metadata registrar is subscribed to the same MQTT broker and, on notification, verifies new/updated metadata and publishes to an OGC API - Records endpoint (powered by pygeoapi) using OGC API - Features - Part 4. The QGIS desktop application is then used to query the OGC API - Records endpoint using its MetaSearch search client.
This session highlights the use of OGC standards with OSGeo software, as well as "no-code" workflow for low barrier metadata management.
Technologies: OGC API - Records, OGC API - Features - Part 4, QGIS, pygeoapi, pygeometa, GitHub, MQTT, Python
Requirements: A basic understanding of OGC APIs and GitHub is recommended.
Stream leader: Tom Kralidis
Proposed schedule: 26th of February, 19:00 - 19:40 UTC - https://www.timeanddate.com/worldclock/meetingtime.html?iso=20240226&p1=224&p2=179&p3=16&p4=44&p5=240&p6=136&p7=133
This event will be succeeded by the pygeoapi code sprint.
