A monitoring system permits to sense the environment, collect and send the observations, manage the data and share the time-series. In real world application, it is very common that most of the system is composed by closed and proprietary parts that may pose a barrier to the adoption of the system due to budget constraints or poor system sustainability. To tackle this problem, the Open Monitoring System Working Group of the OSGeo's Open Geoscience Committee, is conducting a series of workshop to disseminate fully open solutions. During the workshop attendees will be exposed to the two main components of a WSN: the monitoring station component based on Arduino microcontroller and to the data warehouse components based on the istSOS software. The workshop will mix theoretical presentations, practical handouts and discussion sessions to rise attendee’s awareness of the system capabilities and challenges but also to enjoy practical work that will lead to the creation of a small local sensor network with real time interoperable data sharing. The workshop will cover the following sections:

• Introduction to Open Weather Station
• Introduction to the SOS standard and to istSOS
• Introduction to Arduino microcontroller
• Programming Arduino board
• Creating a station connecting Arduino with a sensor and reading data
• Registering the new sensors to istSOS
• Inserting, Manipulating & Validation of observations
• Plotting observations on the Web

Up to today, dealing with application schema features, such as data harmonised to the INSPIRE or OGC data models, also known as complexFeature GML application schemas, was challenging for users due to the lack of appropriate tools in the commonly used client applications. As a result XML content available from GML files or OGC WFS and SOS servers were hard to reuse creating a chicken and egg situation: no interoperable data <–-?--> no client. Recent advances in GDAL/OGR and QGIS will allow easier handling of those app-schema compliant data. BRGM, the European Environment Agency (with the support of European Union's Earth observation programme Copernicus) and JRC have teamed up with core open source actors and QGIS and GDAL/OGR committers (Titellus, Spatialys, Oslandia, Camp to Camp). The functionality will become available from the upcoming 3.0 version of QGIS and 2.2 of GDAL/OGR. In this workshop we will guide you through the world of application schemas in GDAL/OGR and QGIS. Since its introduction the GML Application Schema (GMLAS) driver has received positive feedback, being for example able to address national schemas used in Finland or Japan, beyond the initial use cases it was developed for (INSPIRE, GeoSciML, GroundWaterML, WaterML2) thanks to the generic approach taken in the source code. We will start the workshop with a section on dataset discovery from within QGIS, by querying a spatial catalogue. We will from there connect to a WFS endpoint to retrieve appschema features. We’ll explain how GMLAS is able to automatically set up a relational datamodel in PostGIS by analysing the application schema and load the GML into the database. QGIS will then be able to visualise the data in a map view. You are invited to modify the data and finally export the data from QGIS as application schema GML. We also invite you to bring some of your personal data to load as and/or transform to an application schema of your choice. Other potential topics to discuss and try out are transformations using Humboldt Alignment Editor (HALE) and exposing appschema features as WFS using Geoserver or deegree. At the workshop we’ll have core developers of GDAL/OGR, QGIS GeoNetwork available as well as OGC/INSPIRE data specification experts.

The term of NoSQL (Not only SQL) databases have been raised as a potential alternative solution which is growing rapidly to provide persistence for free schema application. They combine the capability of data sharding in a non-relational structure. This type of databases can potentially accommodate variety of information from Volunteered Geographic Information (VGI) with different structures and schemas into one single geodatabase. For instance, MongoDB introduces an open source NoSQL document-based storage with a replication using data partitioning approach. This approach supports a robust specific query task by using geospatial index of simple point feature. In specific, JSON format in MongoDB is used as a data model on a basis of a document-based rather than on a tuple basis. This situation provides lightweight query and data transfer to support efficient operation especially for Geographical Information System (GIS). However, GIS is a mature system that is already extensively developed using conventional RDBMS approach on the operational levels. Therefore in this workshop, we will demonstrate an implementation of NoSQL database to perform complete mandatory task i.e. Create, Read, Update, and Delete (CRUD) operations by using GIS desktop platform. It shows a reliable performance for handling big data from different sources e.g. Open Street Map (OSM).

One of the biggest problems in most software systems is managing the inter-dependency among its components. Geodjango has dependencies on multiple geospatial libraries and path settings, as does PostGIS. Isolating them using docker containers allows us to build a microservice which is secure and portable. The aim of this workshop is to show how GeoDjango and Docker can be used to create a clean, portable and isolated geo-service, and to understand the rationale and implications of using this method to develop mapping websites. By the end of this workshop, developers will build a beautiful web application displaying road accident data for different counties in the UK, by creating a docker micro-service to serve the geographical data, and use Javascript library called Openlayers to display the data.

GeoNode is a Web Spatial Content Management System based entirely on Open Source tools whose purpose is to promote the sharing of data and their management in a simple environment where even non-expert users of GIS technologies can view, edit, manage, and share spatial data, maps, prints and documents attached. GeoNode is an open source project initiated in 2010 by the World Bank and OpenGeo (now Boundless), but from 2011 is entirely run by the developer community that the project has been able to attract. It claims some large organizations among its contributors such as the United Nations, the World Bank and the European Commission as well as many NGOs and private companies. GeoNode is based on a set of robust and widespread open source components as Django as a basic framework, GeoServer for geospatial data management and OGC services and OpenLayers/Leaflet as mapping application. It can also communicate with PostgreSQL for vector data management. The purpose of this workshop is to introduce the attendees to those which are the GeoNode current capabilities and to some practical use cases of particular interest in order to also highlight the possibility of customization and integration. Finally, we will present a number of new features and changes that have been recently developed or are developing and will also outline what are the future directions of the project evolution.

The workshop will focus on the implementation of a GeoNetwork opensource based catalog to facilitate discovery and access to geospatial data in a Spatial Data Infrastructure. GeoNetwork opensource is the geospatial catalog of choice in most European National portals as well as in many other countries, cities and organisations around the world. We will start from a basic installation to get to your own dedicated catalog based on the latest GeoNetwork stable version 3.2. Harvesting of spatial data resources from remote servers will be configured and geospatial web map services will be set up using the embedded GeoServer and configured for access through the catalog web interface. QGIS (metasearch) will be used as an alternative user interface to query GeoNetwork. Participants will create metadata and learn how to develop and use custom metadata templates based on the ISO19115/19119 metadata standards. Participants will learn to use the various different interfaces that GeoNetwork offers, such as the GUI Web Interface and the OGC CSW/ISO interface. Attention will also be given to other import and export functionality of the catalog that allow integration of the publishing process in existing workflows, linked data and search engines. We will present some of the new features available in the upcoming 3.4 release.

pgRouting adds routing functionality to PostGIS. This introductory workshop will show you how. It gives a practical example of how to use pgRouting with OpenStreetMap data. It explains the steps to prepare the data, make routing queries, assign costs, write a custom ‘plpgsql’ function and use OpenLayers to show your route in a web-mapping application. Navigation for road networks requires complex routing algorithms that support turn restrictions and even time-dependent attributes. pgRouting is an extendable open-source library that provides a variety of tools for shortest path search as extension of PostgreSQL and PostGIS. The workshop will explain about shortest path search with pgRouting in real road networks and how the data structure is important to get faster results. Also you will learn about difficulties and limitations of pgRouting. We listened to the student's feedback of the last years and want to guide you through the basic steps to build a simple browser application. Our goal is to make this as easy as possible, and show that it’s not difficult to integrate with various FOSS4G tools.

GRASS GIS is a Free and Open Source geographic information system (GIS) with support for raster, 3D raster and vector data processing. It provides more than 450 core modules, plus hundreds of Add-ons, to run any kind of geographical analysis. GRASS GIS offers a useful graphical interface to work as in any other desktop software. However, the highest power of GRASS GIS resides in that it can be used also like a backend tool to run analysis in an automatic way, not only a personal computer, but also into HPC systems or via web services (WPS or scripting in several languages). The workshop will show the basics about GRASS GIS, it will be an intuitive mix of theoretical and hands-on sections. In the former, we will introduce the participants to some specific concepts of GRASS GIS, like its database structure, location, mapset and region and will show how simple the approach really is. During the hands-on part, the participants will learn how to use common geographical data formats in GRASS GIS, starting from simple actions like adding data into the GRASS GIS environment and displaying it. Finally, the participants will run simple analyses like map algebra calculations for raster maps and vector buffering and visualize and export the results.
