GeoServer Feature Frenzy (FOSS4G 2022 Edition)

GeoServer is a web service for publishing your geospatial data using industry standards for vector, raster and mapping. It powers a number of open source projects like GeoNode and geOrchestra and it is widely used throughout the world by organizations to manage and disseminate data at scale.
What can you do with GeoServer? This visual guide introduces some of the best features of GeoServer, to help you publish geospatial data and make it look great! GeoServer has grown into an amazing, capable and diverse program - with a feature list spread over years of release announcements, presentations, and mailing list archives.
This presentation provides:

A whirl-wind tour of GeoServer and everything it can do today.
A visual guide to some of the best features of GeoServer.
Our favorite tricks we are proud of!

Are you just getting started with GeoServer, or considering it for the first time? Attend this talk and prioritize what you want to look into first. Are you an expert user who has been running GeoServer since version 1.0? Attend this talk and see what tricks and optimizations you have been missing out on.

  8. Many of these are provided by extensions

  9. Configuration

  10. GUI: GeoServer for point & clickers

  11. GUI: GeoServer for point & clickers

  12. GUI: GeoServer for point & clickers

  13. Style editor

  14. But you’re not limited to point and click, REST!

  15. Need to mass-configure layers? Importer! GUI and REST

  16. Bit of safety: backup and restore extension • Save the

    configuration to a zip file (not the data!) • Restore later, in the same or different environment • UI to run backup and restore • Async operations • REST Interface • During backup the configuration is read only • During restore it’s fully locked • Support “dry run” to for errors prior to restore
  17. Vector data sources

  18. Files files, many little files (OGR)

  19. SQL

  20. Everybody loves curves • Read curved geometries from Oracle and

    PostGIS, paint them, GML output them, linearize everywhere else
  21. SQL-Views GeoServer WMS/WFS ... DB2 Any DB ... Run query

    as layer source
  22. Parametric SQL Views GeoServer WMS/WFS ... DBMS Any DB ...

    Inject params from request Run query as layer source
  23. NoSQL!

  24. Feature Type Customization and Filtering

  25. Distributed!

  26. Raster data sources

  27. Run of the mill Old but gold! Simple Mosaic ArcGrid

    Fully configured Mosaic (custom schemas, attributes, filtering, sorting, custom storage)
  28. Going native GDAL 3.x (NITF files) Fast JPEG2000 libdeflate Read/Write

    TIFFs Write JPEGs maps Read/Write TIFFs
  29. Maps, maps everywhere!

  30. Basic maps

  31. Samples from IGN (using SLD)

  32. OSM? Yes OSM! (With CSS this time)

  33. GeoServer handles dateline, projection limits, high accuracy projection grids, and

    so on Reproject with confidence Dateline wrap Cut on UTM Cut on polar stereographic Densify for smooth reprojection
  34. Only want to play with MVT? Ok! • Extension for

    publishing vector tiles • Great solution for modern High Definition Screens • Client side styling • Use for GeoServer for “MapBox without MapBox” • Also to do “MapBox with OGC fallback”
  35. Integrated tiles cache

  36. GeoWebCache • Tile caching application • Can cache tiles in

    PNG/JPG/KML/MVT/GeoJSON • Can store tiles in file system/SQLite/S3/Azure • Supports WMS-C, TMS, WMTS
  37. Runs integrated in GeoServer • Configuration integration ◦ Configure layer

    once ◦ Setup via GUI • Security integration ◦ Configure security once ◦ Limited checks (only layer access, no attributes, areas and alphanumeric filters) • Event integration ◦ Change styles, tiles dropped ◦ WFS-T transaction, tiles dropped • Service integration ◦ Direct integration ◦ Intercept tiled requests from WMS and uses cache for them
  38. Deliver data

  39. WFS and WCS • Download vector data • Filter, reproject,

    join, page • Download raster data • WCS 2.0, a protocol humans can understand
  40. CQL POP_EST <= 5000000 AND POP_EST >100000 A lightweight “domain

    specific language”: • CQL - is a standard from OGC Catalog • E-CQL - extends this basic concept to do everything Filter can do
  41. CQL POP_EST <= 5000000 AND POP_EST >100000 A lightweight “domain

    specific language”: • CQL - is a standard from OGC Catalog • E-CQL - extends this basic concept to do everything Filter can do In GeoServer CQL can filter raster data too… in particular, mosaic images with associated attributes
  42. Editing data since 2003 (the original superpower) WFS-T PostGIS Oracle

    Shapefile SQLServer ...
  43. App Schema

  44. Complex GML making your eyes bleed? { "type": "FeatureCollection", "features":

    [ { "type": "Feature", "id": "0001000001", "geometry": { "type": "Point", "coordinates": [51.0684, 1.4298] }, "properties": { "@featureType": "Borehole", "identifier": { "value": "BSS000AAAA", "@codeSpace": "http://www.ietf.org/rfc/rfc2616" }, "bholeHeadworks": [ { "type": "Feature", "geometry": { "type": "Point", "coordinates": [51.0684, 1.4298] }, "properties": { "@featureType": "BoreCollar", "collarElevation": { "value": -32, • No worries • Your 2020 nighmares will be made of complex GeoJSON instead!

  46. Process!

  47. • Analyze, publish, transform on the fly, access local data

    Integrated WPS
  48. Think small • Small is useful • BBOX for filtered

    datasets • Aggregation processes, provides datasets for building charts (group and count) • Clip and ship • Build animations
  49. Think big! • Start remote processing nodes, track their progress

    • Register the result as a GeoServer layer for preview before download
  50. Rendering transformations: process and render at the same time

  51. On the fly contour extraction from styles

  52. Jiffle and rendering transformations nir = src[7]; vir = src[3];

    dest = (nir-vir)/(nir+vir); Map Algebra at your fingertips On the fly, or batch with WPS
