Creating web-mapping applications with QGIS Server and QWC2

Eric LemoineRoom 5

QGIS Server has become a serious competitor in the realm of map engines for the web. Maps served by QGIS Server are designed in QGIS Desktop, and rendered by QGIS Server with the same rendering engine as QGIS Desktop. This makes it possible to leverage QGIS advanced styling capabilities, which, in itself, is a major advantage over its competitors. A number of JavaScript applications, frameworks and SaaS solutions exist for QGIS Server. QGIS Web Client 2 QWC2 , LizMap, GW3 Suite, GIS Quick are examples. QWC2 provides both an off-the-shelf web application and a development framework. QWC2 thus makes for a very flexible tool; you can start simple and easy with the demo application, and then customize your application at will, based on your needs and development capabilities. In this workshop you will learn how to set up QGIS Server, create a QWC2 application, and the different levels of customization that you can apply for web-mapping applications that suit your needs and taste.

Geopaparazzi: never out of data in the field

Silvia FranceschiRoom 2

The workshop is dedicated to professionals, researchers and students that needs to collect data from the field and use this information to update or create GIS data, but also to OpenStreetMappers as well as tourists that want to keep a geo-diary. Geopaparazzi is an easy to use and intuitive mobile application for digital field mapping for Android devices developed to support the work of the technicians in the field, offering a mapping environment with real time GPS position and the possibility to take georeferenced notes, georeferenced and oriented pictures and georeferenced sketches. Furthermore, Geopaparazzi provides a powerful support for structured data collection based on customized forms. Forms may contain combo and check boxes, text fields, pictures and sketches organized over multiple tabs. Background data on the map view can be personalized using available local data or on-line services with the possibility to use vector offline Mapsforge basemaps, Mbtiles offline databases, TMS and WMS services. Vector layers in Spatialite DB can be visualized in the map view with a style prepared on the device or directly imported in the DB from SLD style files and edited with simplified tools developed to be used on a device in the filed. In the last years we developed some applications in the HortonMachine library to support Geopaparazzi, which supply an userfriendly GUI with specific functionalities to prepare the base raster data for the map view in Geopaparazzi, prepare the overlay vector layers as Spatialite DB with the support of the styling original SLD , prepare the forms with all the detailed sections, visualize and export as shapefiles of all the data collected in the field GPS tracks, text notes, pictures and form based notes . The workshop starts with an introduction of the application, installation and description of the main features. Then a short section will be dedicated to the preparation of the input data background maps, vector layers and forms. Following these sections there is a practical testing of Geopaparazzi outdoor in the field. The last section, back in the room, is dedicated to the export of the collected data. The data collected can be visualized or used directly in a GIS environment using everyone s preferred GIS or can be synchronized with the data collected by the other surveyors of the team using the new web application Geopaparazzi Survey Server.

FOSS tools for modelling natural hazards: the HortonMachine library

Silvia FranceschiRoom 4

The climate change and the recent extreme events occurred all over the world draw again the attention to the natural hazards both for prevention and for management aspects. In this context, environmental modelling can help in managing geospatial data, mapping hazards and risks zones and support decision makers in building functional infrastructures with low environment impact and for a safe urban planning. In the context of modelling natural hazards hydro-geomorphology analysis is a key aspect. In the last decades many researchers tried to extract useful information from digital data and in particular from Digital Terrain Models DTM with the development of ad-hoc algorithms and tools. In the meanwhile the data availability increased and high precision DTM are available almost all over the world. There are many possibilities to analise natural hazards and to define hazard and risks zones as required by the national and international directives. The algorithms contained in the HortonMachine library are the result of more than 10 years of research, development and real application of people from different research institutes and professionals working in the field of environmental engineering. The HortonMachine library contains tools for data management raster, vector and point cloud , data collection in the field, and environmental modelling in particular related to hillslope stability, floods, debris flow and woody Large Wood floods. The workshop will cover the main aspects of the hydro-geomorphological analysis of a river basin starting from a DTM. The aim is to evaluate the maximum discharge that can occur in a section for a given precipitation or using statistical information derived from the Intensity Duration Curves. Some generic geomorphological analysis on the DTM will be performed that will be used to delineate the stream network and the watershed closed at the desired section. The last step will be the evaluation of the hillslope stability and of the maximum discharges using the shallow stability model Shalstab and the semi distributed model Peakflow integrated in the HortonMachine library. The expected participant is the average GIS user that wants to approach new tools for environmental modelling related in particular to natural hazards. The user can be a professional, a person of the public administration or even a decision maker who has average knowledge of GIS and GIS data and wants to approach this topic. The HortonMachine library is a package of applications and tools and does not have a specific GIS support. The visualization of the data and results can be done with anyone s preferred GIS.

Object-based image analysis (OBIA) with GRASS

Moritz LennertRoom 1

GRASS GIS https exists for more than 30 years and provides a very large and diverse set of state-of-the-art tools for the analysis of spatial data. Less known by many, remote sensing tools have been part of it almost from the beginning. GRASS GIS provides a series of imagery analysis tools for pre-processing radiometric correction, cloud detection, pansharpening, etc , creating derived indices vegetation indices, texture analysis, principal components, fourier transform, etc , classifying management of training zones, different classifiers, validation tools , and producing other derived products such as evapotranspiration and energy balance models. Next to these tools for satellite images, other tools exist for the handling of aerial photography for creation of orthophotos, and for the import and analysis of Lidar data. In addition to these tools, efforts have gone into integrating current state-of-the-art methods such as object-based image analysis OBIA and machine learning. A complete toolchain exists to segment images using different algorithms, to create superpixels, to collect statistics characterizing the resulting objects, and to apply machine learning algorithms for classification. New modules also include unsupervised segmentation parameter optimization and active learning. Options for pixel-based classification have also been enlarged to a host of machine learning algorithms. In this 4-hours hands-on workshop, users will learn how to use the entire OBIA toolchain in order to create a classification of a very-high resolution image. We will go through all the steps from segmentation all the way to classification. All the steps will be run via the GRASS GIS GUI, but we will also demonstrate how these tools can be used in an automated fashion through scripts.

Thriving in hybrid ESRI & Opensource environments

Paul van GenuchtenRoom 3

A hybrid architecture of proprietary components ArcGIS, FME, Oracle and open source components OpenLayers, OGR, QGIS, GeoServer is common in many organizations. But it has its challenges. Data and map projects are hard to share between departments, due to proprietary formats and encodings. In this workshop we introduce you to a set of best practices and tools that will facilitate better interoperability within the organization and with external partners. Ground principle is the adoption of OGC standards, which are generally supported in open and proprietary software. Alternatively various plugins are available to support these standards. GeoCat Bridge is such a tool, an ArcGIS Desktop plugin which gets you, as an ArcGIS user, easily started with OGC standards and the OSGeo stack. After this workshop you will be able to identify challenges in any hybrid data infrastructure, have awareness how to prevent and solve them. If you bring a device having ArcGIS Desktop, you will also publish your first map from ArcMap to GeoServer and visualize it in OpenLayers without touching a line of code.

Extraction, analysis and dataviz on open geospatial datasets

Raphaël DelhomeRoom 5

Since a few years, open data portals have become more and more popular, allowing experienced users to download and exploit a wide range of datasets, among which georeferenced ones. This workshop will demystify the exploitation of such data, by illustrating typical data processing with a concrete example, e.g. analyse a bike-sharing system in a given city - extract data from open data portals and put it into a database; - product new information through machine learning techniques; - display data with a public API and visualize it with a web application. All these steps will be achieved with a lot of Python and a bit of Javascript, without forgetting PostgreSQL and its PostGIS extension to store georeferenced data. The workshop is intended for intermediate users, with basic knowledge in Data Science and Python Javascript. Live coding through Jupyter Notebooks will take up the major part of the workshop, and attendees will be encouraged to handle data.

Introduction to GeoNetwork Opensource

Paul van GenuchtenRoom 2

The GeoNetwork Opensource project has been an OSGeo project since a decade. It is a catalog application facilitating discovery of resources within any local, regional, national or global SDI. Users can register their spatial datasets, services, maps, sensors in a central catalog. Others can query the catalog to find resources via the website or directly from a GIS application like GeoNode or QGIS. The catalog records can also be ingested by other catalogs and search engines to facilitate wider discovery. In this workshop the main contributors to the project will explain use cases around spatial catalogs, relevant OGC and W3C standards, the use of GeoNetwork in local and regional setups and an introduction to the GeoNetwork community. We ll quickly go through setup and configuration and try to fill it with your own data. At the end of the workshop, attendants will understand what a spatial catalog is, how it relates to a Spatial Data Infrastructure and they will be able to deploy and administer their own spatial catalog. GeoNetwork OpenSource is used as regional or national catalog in many countries all over the world. The catalog is ready for INSPIRE, it facilitates various meta data encodings that are ingested and exposed through OGC and W3C services.

QGIS and PostGIS meet in 3d dimension

Vincent PicavetRoom 9

While the superstring M-theory counts 10 dimensions in our universe, for the sanity of the workshop participants, we will focus on 3-dimensional space. PostGIS, the well-known spatial database, has a set of functions allowing for the manipulation of 3D data. It features extrusion, union, buffer and more. Moreover, this set of 3D features is fully compatible with all other PostGIS and PostgreSQL functions, and enables the user to mix 3D objects with classic 2D features, but also with PostGIS raster data or even Point Cloud data. QGIS, the desktop GIS software, has recently made a lot of progress in the 3D visualization area, and is now able to display 3D objects alongside standard 2D views. In this workshop, we explore PostGIS 3D capabilities, and use QGIS to visualize the resulting data. image https -4k9mNIcN1zI V5aoYDnfGwI AAAAAAAANpo W5367fBNRLIXRX37eniKPi7TsYg5KLY6ACLcB s1600 It-Came-HSB edited-1.gif IT from outer space

Introduction to MapStore, mashups made simple

Mauro BartolomeoliRoom 1

This workshop will provide an introduction to creating geospatial mashups using the MapStore Open Source product and framework. MapStore is the Open Source product for creating, saving and sharing in a simple and intuitive way maps and mashups created selecting contents from public services like Google Maps and OpenStreetMap or other servers implementing OGC and ISO protocols. Thanks to MapStore the user can mix her own data with data available on the web to create comprehensive maps and share them with anyone also via social networks . MapStore is cross-browser, and mobile ready. We will show how to create and navigate maps. We will also show how the framework can be used to create a custom WebGis project. In order to participate to the workshop a working knowledge of JavaScript and OGC services is recommended.

PostgreSQL/PostGIS for Beginner

Astrid EmdeRoom 9

PostgreSQL is a powerful, open source object-relational database system. It can be extended with PostGIS which allows you to store and handle geospatial data in the database. This combination is very successfull and allows you many possibilities. Many processes that you did before with you Desktop GIS f.e. intersection, union, buffer can be easily done via SQL using PostGIS functions. In the workshop you will get to know the database PostgreSQL and the extension PostGIS. There will be an introduction to PostgreSQL and SQL and you will learn SQL basics to create and modify data. You also will get to know the concept of PostGIS and how geodata is stored in the database. You will get an overview about the enormous possibilities of PostGIS. In the workshops hands-ons we will concentrate on 2-dimensional data and we will use OSGeoLive for demonstration. You will learn how to store, import and use geospatial data in the database. With QGIS you will discover how easy it is to bring your data to the database and out of it. You will learn how to analyse and modify your data and learn how to make transformations, intersections, length distance calculations, buffers, unions and more. Everything is possible with some magic lines of SQL.

R for Geospatial Processing

Nicolas RoelandtRoom 5

Spatial manipulation and cartography with R software has been made easy and fun in recent years. R is an open source language and environment for statistical computing and a major player in the field of data science. Its community is one of the most welcoming and inclusive communities for programmers. In this respect, it is very similar to the OSGeo community. Until recently, although possible, geospatial manipulations or creating nice maps were not easy in R. But things have changed for the best Packages like sf that allow easy Simple Features manipulation with direct connection to GDAL, GEOS, PROJ, and geospatial functions offer a new tidy and easy way to manipulate spatial data. R is a powerhouse for geostatistical analysis with tried and tested algorithms for spatial auto-correlation Moran s I, Geary indices , spatial interpolation kriging, etc , and many more. Many packages allow one to create nice and decent maps, even interactive ones for the web This workshop is aimed at all levels of participants, from newcomers to GIS veterans and R users who want to get a grasp on spatial data and spatial analysis It will cover R basics, data manipulation, spatial operations, and cartography. Detailed Outline this tutorial will cover a variety of techniques that will help the user to manipulate geospatial data within R to produce insightful output. An overview of the topics covered are Understanding R basics dataframes, functions, etc Understanding spatial data in R Loading and manipulating spatial data vector, raster, projections Using spatial algorithms Creating maps and web maps

Spatio-temporal data processing and visualization with GRASS GIS

Veronica AndreoRoom 3

GRASS GIS https is a general purpose Free and Open Source geographic information system GIS that offers raster, 3D raster and vector data processing support. GRASS GIS has also incorporated a powerful support for time series, the so called TGRASS . Through this, it became the first open source temporal GIS with comprehensive spatio-temporal analysis, processing and visualization capabilities. The temporal functionality makes it easy to manage, analyse and visualize climatic data, vegetation index time series, harvest data or land use changes over time. Raster, vector and 3D raster time series are handled through a special data type called space time data sets STDS which are used as input in TGRASS modules. TGRASS incredibly simplifies the processing and analysis of large time series of hundreds of thousands of maps . For example, users can aggregate a daily time series into a monthly time series in just a single line; they can retrieve the date per year in which a certain value is reached; select maps from a time series in time periods in which a different time series reaches a certain value; perform different temporal as well as spatial operations among time series, and so much more. In this 4-hours hands-on workshop we will present and exemplify the use of a subset of the more than 45 temporal modules in combination with other GRASS GIS modules and Add-ons in a workflow starting from the download of remote sensing data to the creation of a simple model and visualization of results. We will first learn how go to create STDS and assign time stamps to maps. In addition, we will learn different methods to gap-fill incomplete data, temporal algebra operations, temporal aggregation, queries and retrieval of basic and zonal statistics for time series. All along the session, we ll see different visualization options available in GRASS GIS. Moreover, we will show how this workflow might be included in python scripts and executed from outside GRASS GIS.
