Still, it can be daunting to be approached without previous experience. This workshop aims to give a basic introduction of working with spatial data in a PostgreSQL database server by showing the attendants how to install a local PostgreSQL server, connect to it, create and manage users and privileges, and create a spatial database with the PostGIS extension. Then we will move to spatial data and learn how load spatial tables, assign primary and foreign keys, and manage the data both with QGIS and other open-source database management programs. During the workshop, Elisa will also share all the lessons learned in the last 5 years of working with PostgreSQL and the dos and absolutely-don'ts that the attendants need to be aware of (capital letters, anybody?). This workshop is hands-on. **Prerequisite skills:** - Attendees should be familiar with QGIS **Preparation required:** - Own laptop with enough memory and space to install and run - PostgreSQL https://www.postgresql.org/ - QGIS LTR or v3.32+ installed https://www.qgis.org/en/site/ **Book your ticket here:** https://ti.to/osgeo-oceania/foss4g-sotm-oceania-2023-workshops. *A total of 25 spaces are available.* false https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/8CHFJ3/ https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/8CHFJ3/feedback/ WF413 Workshop 2023-10-16T13:00:00+13:00 13:00 04:00 Going beyond all the common functions that most folks use PostGIS for. Delving into advanced use cases and using PostGIS in production workloads. foss4g-sotm-oceania-2023-1613-advanced-postgis-beyond-the-basics Workshop Rhys Stewart en PostGIS, sitting on top of Postgresql, is by most metrics, the most popular spatial database. Many videos are online about how to install and use PostGIS....many are from prior FOSS4G conferences and do a good job in getting you to understand the basics. Most of them, however, only scratch the surface when it comes to the power that can be wielded with PostGIS. This workshop seeks to explore a wide array of functions that may not be used on a regular basis or are outside the scope of common spatial queries. These include, but are not limited to: - Linear Referencing - Clustering - Using rasters - Vector Tiles There will also be an emphasis on using PostGIS in production, so there will be some usage of other software products (for example: Martin Vector tile server or pg_featureserv or pg_tileserv ). Consideration will also be given to the ecosystem around PostGIS (For example: ogr_fdw) **Book your ticket here:** https://ti.to/osgeo-oceania/foss4g-sotm-oceania-2023-workshops. *A total of 25 spaces are available.* false https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/GENTA3/ https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/GENTA3/feedback/ WF314 Workshop 2023-10-16T08:00:00+13:00 08:00 04:00 The QGIS Model Designer is a powerful tool that we can use to define a workflow and run a chain of algorithms (a processing model). In this workshop we will create a processing model in the QGIS Model Designer and learn how to effectively use some of the features. foss4g-sotm-oceania-2023-1267-creating-models-using-qgis-model-designer Workshop /media/foss4g-sotm-oceania-2023/submissions/FRCTKF/qgis_model_designer_4aGQacG.png Simon Nitz en A normal session with the processing framework tools includes more than running a single algorithm. Usually several of them are run to obtain a result, and the outputs of some of those algorithms are used as input for some of the other ones. Using the QGIS Model Designer, that workflow can be put into a processing model, which will run all the necessary algorithms in a single run, thus simplifying the whole process and automating it. In this workshop we will create a processing model in the QGIS Model Designer that displays buildings affected by some event within a distance from an event location. The affected buildings are determined by: - Clicking a point on the map canvas to define an event location, - Traveling a distance along the road network from the event location, - Buffering the travel distance to intersect land parcels, - Extracting building footprints that that intersect the land parcels. **Prerequisite skills:** - Attendees should have some familiarity with QGIS **Preparation required:** - Laptop - QGIS 3.28 LTR better installed https://www.qgis.org/en/site/ - Workshop files https://data.whanganui.govt.nz/wdc/foss4g/2023/Workshops.zip **Book your ticket here:** https://ti.to/osgeo-oceania/foss4g-sotm-oceania-2023-workshops. *A total of 25 spaces are available.* false https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/FRCTKF/ https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/FRCTKF/feedback/ WF314 Workshop 2023-10-16T13:00:00+13:00 13:00 04:00 Learn how to use Kart to version control your spatial data with the Kart CLI and QGIS plugin. foss4g-sotm-oceania-2023-1390-spatial-data-versioning-collaboration-with-kart Workshop Hamish Campbell en Kart (https://www.kartproject.org) is a powerful new open-source and cross-platform version control system for geospatial vector and table data.

Maps and the products we use to consume them have the biggest impact on the world when these principles are adhered to. How many government portals have you visited where a carefully curated map is presented that hardly anyone sees let alone uses? Presenting the data to the user in an intuitive way that helps them make a decision or take action is essential. Large paper maps of the 1700s were well suited to a captain’s desk as their ships traversed the oceans. Road atlases of the 20th century helped to spur family adventures and weekend getaways as highway networks were constructed around the world. The small computers in our pockets today allow us to see when the next train will arrive and which one will get us home sooner. These examples took the technology of the day and used it to make products with significant impact on society. The mobile internet in particular changed mapping in one of the most notable ways since humans started abstracting 3D space on 2D surfaces. We’re on the cusp of another great shift in the way maps are used with many exciting use cases awaiting discovery. The technology powering this potential is Augmented Reality (AR). This talk will explore some of the use cases that AR is supporting and where it might be useful in future. We’ll look at how AR can be accessed and how the medium of access affects its utility. With these use cases in mind, we’ll assess how open tools and map data enable AR. Some of the data and tools we’ll look at include: * Geometries of pedestrian ways * Associated attributes: Incline, safety, lighting, access, surface type, accessibility features * Building entrances * 3D building data * VPS for localisation * Routing algorithms The talk will conclude with a summary of Meta’s approach to map building and how open source geospatial technology powers the maps we build for today and the years ahead. false https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/MAR9VW/ https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/MAR9VW/feedback/ Plenary Talk 2023-10-17T11:25:00+13:00 11:25 00:25 We record the extent and shape of the beach over time to monitor coastal changes, foss4g-sotm-oceania-2023-1653-mapping-reef-islands-in-3d Talk Maria Kottermair en Reef islands and coral cays like Heron Island on the Great Barrier Reef are highly dynamic and change in shoreline horizontal and vertical positions can occur rapidly over days or slowly over years to decades. Reef island environments are severely impacted by sea level change and human activities like dredging and shoreline hardening. These impacts are likely to be exacerbated in a future of higher sea levels and changing wave climates. Despite this there are very few studies that have examined shoreline and volumetric change of low-lying reef islands over time. Measuring the horizontal position and three-dimensional volume of low-lying reef islands at high spatial resolution (< 1 m) and precision over several seasons and years will provide a better understanding of the processes driving shoreline change and coastal erosion and accretion. In June 2023, we collected field data on Heron Island to characterise the intertidal zone and beach area using drones, laser scanners, and GNSS. The results from this study will help inform shoreline monitoring, management strategies and mitigation measures, facilitate greater accuracy in modelling future island states, and help ensure sustainability of the island. The overall aim is to protect the important ecosystem reef islands provide and to offer insights into tropical island change that will be relevant globally and throughout the entire Great Barrier Reef. false https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/78CWNX/ https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/78CWNX/feedback/ Plenary Talk 2023-10-17T11:50:00+13:00 11:50 00:25 A presentation on the new Toitū Te Whenua Land Information New Zealand (LINZ) LiDAR QC command line application that has been developed using open-source software and libraries, including Python, GDAL, PDAL, and LASTools. foss4g-sotm-oceania-2023-1647-improving-lidar-qc-processes-using-open-source-software Talk /media/foss4g-sotm-oceania-2023/submissions/FL7FA7/check_dataset_output_BXlQqbP.PNG Abbey DouglasAndrew Jacombs en The command line application was developed to improve LiDAR data quality checking (QC) processes, as part of the National Elevation Program.

In collaboration with NIWA, VMGD has undertaken a project to create spatial maps of historical climate data in Vanuatu and develop operational climate anomaly maps from recently observed rainfall and air temperature data. This project aims to strengthen the capability of the VMGD climate staff to interpret and generate maps based on rainfall and air temperature observations. The outcomes of this project include the creation of an atlas of maps of the past climate for Vanuatu. Within this atlas, monthly and seasonal maps illustrate the historical long-term average rainfall and air temperature for Vanuatu, specifically highlighting the different phases of the El Niño-Southern Oscillation (ENSO). Moreover, a suite of operational climate maps has been generated, describing temperature and rainfall patterns for the past 30, 60, 90, 180 and 360 days in Vanuatu.

The AODN contains data observed by the Integrated Marine Observing System (IMOS) program and partner organisations from across Australia. All data are shared under an open license and published using open source geospatial software through a platform that has been running on Amazon Web Services for eight years. The wide variety of types of marine data that we host means that we cannot rely on a single strategy or tool to store and provide data. Additionally, there has been recent work around the globe to establish new cloud native ways of storing, accessing and analysing large volumes of data. The AODN has recently undertaken reviews into cloud-native data formats such as GeoParquet, Zarr, TileDB and Kerchunk. In one case we found we could complete a workload 1900 times faster using cloud-native formats than with our legacy solution. This talk will cover the modern cloud-native formats we have been exploring, our assessment of them and the challenges we have faced, as well as highlighting some questions that remain over the use of these cloud native formats.

These functions run client-side in the browse meaning geospatial data never leaves the computer unprotected, presenting a completely trustless mechanism for sharing data. foss4g-sotm-oceania-2023-1848-mapsafe-a-complete-tool-for-achieving-geospatial-data-sovereignty Talk Dr Pankajeshwara Sharma en Sensitive geographic data are invaluable assets for the people to whom they belong and their disclosure should be decided by the sovereign data owner (SDO). Due to several high-profile data breaches and business models that commercialize user data, the need for new approaches to geoprivacy and data sovereignty has grown. We propose MapSafe, a client web application that first obfuscates datasets using donut masking or hexagonal binning, separately, and thereafter implements a multi-level encryption scheme that permits SDOs to share the final encrypted volume containing the geospatial information when they choose and at a level of detail which they are comfortable. The authenticity verification of the volume is facilitated by storing the hash value corresponding to the encrypted volume immutably on the Blockchain as a public record. Our approach places geoprivacy under data guardians'’ control, and its integration capabilities promote its adoption in existing and future geospatial web systems. false https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/VDQLXB/ https://talks.osgeo.org/foss4g-sotm-oceania-2023/talk/VDQLXB/feedback/ Te Iringa Talk 2023-10-19T14:00:00+13:00 14:00 00:25 Does the management and sharing of information present challenges for your organisation?

This is currently an area lacking in FOSS4G and whilst there are some products out there, they mostly require payment or have limited functionality. If we can come out of this with our requirements, we could then understand the resource requirements and build a crowdfunding exercise. Our Goals - What elements do we require? The base would include media, text, and map. However, perhaps we want to be able to view it 3d or create some dashboard like features. - What should their behaviour be? Think about what is currently out there - what do you like, what is missing & etc. We want to progress further than a map and an information box side-by-side. - What should the base platform be? Think here about the resources for continual maintenance, accessibility, logic, ease of use. What currently offers this, could we approach them to build up their product with our requirements? Would be be able to roll what is available out there into the QGIS platform to allow for ongoing technical support? > Please contact emma@north-road.com with any of your ideas.
