Coverage views from heterogeneous bands 2.13 Source data (e.g. Sentinel 2) A new feature in 2.13 is the ability to define a coverage view using mix bands from seperate files, at different resolutions, into a single multiband coverage view. Daniele Romagnoli - Andrea Aime GeoSolutions DLR Virtual multiband coverage Select 3 bands and contrast stretch 

S3 GeoTIFF Community Module + Mosaic Support for GeoTiffs hosted on Amazon S3 ● In 2.14.x, can be coupled with image mosaic to support mosaics of AWS images (experimental!) 2.12 - 2.14 Devon / Niels Boundless Boundless s3://landsat-pds/L8/001/002/LC80010022016230LGN00/LC8001 0022016230LGN00_B1.TIF?useAnon=true&awsRegion=US_WEST_2 

Web Map Service Got maps? 

Nearest match in time dimension ● Time dimension now supports “nearest match” ● Map will return the closest time to the one selected ● Possibility to set a search “radius” ● The actual time used is returned in a HTTP response header 2.14 Andrea Aime GeoSolutions EUMETSAT 

WMS sortBy vendor param ● Sort by recency, cloud cover, and so on ● Supported by vector data and image mosaic 2.12 Andrea Aime GeoSolutions DLR Mosaic sorted by recency Mosaic sorted by cloud cover 

Better centroid / label placement in “vector” outputs KML ● generate placemarks that are always inside polygon (for concave polygons) Vector Tiles ● Pregenerate label points in tiles ○ Reduce effort on client 2.12 Kevin Smith Justin Deoliveira RnD Label Label vs 

Web Feature Service To the source of vector data! 

Almost WFS 2.0 certified compliant ● Lot of work went into making GeoServer pass the WFS 2.0 certification on simple features ● 48 issues fixed ● Almost there, still a couple of minor fixes to do (but so many other urgent things to work on…) 2.12 - 2.13 - 2.14 Andrea Aime GeoSolutions OGC and GeoSolutions 

1 -2 10 0 1 3 15 1 5 3 20 2 5 -2 25 3 Nuno / GeoSolutions Jody / Boundless Encode coordinates measures - Enable to encode coordinate measures (“M”) in WFS output formats that support measures. - PostGIS is supported today! WFS Measure Support Community 2.14 

App-schema improvements ● Improvements to connection pool usage (only one connection used per request now) ● Some improvements helping while using MongoDB as a source for app-schema records ● Hale mapping support being extended to support MongoDB ● Support for SOLR as a data source for MongoDB, as well as secondary index for full text search engines 2.12 - 2.13 - 2.14 Nuno Oliveira GeoSolutions NPRA 

Web Coverage Service To the source of raster data, too! 

CQL_FILTER and SORT_BY on mosaics ● Sort by recency, cloud cover, and so on ● Filter on the same ● Maps to image mosaic read parameters ● Uses attributes in the mosaic index ● Consistent with WMS now, first see and then download 2.12 Andrea Aime GeoSolutions DLR 

NetCDF input/output improvements 2.12 Niels (Scitus) Ben (Transient) Community ● Can configure NCML files as sources ● Support variable attribute definition in NetCDF output ● Copy scalars from NetCDF/GRIB source ● Copy scalars from source granules to make vector in NetCDF output 

GHRSST Community Module ● WCS output format plugin ● Builds a NetCDF file complaint with the “Group for High Resolution Sea Surface Temperature” specification ● It’s the first multi-coverage output, e.g. ○ Sea surface temperature ○ Sea ice fraction ○ Quality level ○ Pixels per bin ○ ... 2.13 Andrea Aime GeoSolutions EUMETSAT 

Tiles My alphabet: X,Y and Z 

● GeoServer supports “cascading” remote WMTS services ○ GeoServer acts as a client, rather than just rerouting each request ○ Same as WMS cascading WMTS cascading 2.12 Ian Turton - Emanuele Tajariol GeoSolutions GeoInfo 

Parameter filter cache drop fixes/improvements ● GeoWebCache can cache based on request parameters like style, time, or elevation. ○ Could not truncate (remove cached tiles) across all parameter values, each must be known and truncated separately. ○ Now truncates all possible values ● Added operations for ○ Cross parameter truncate ○ Orphan purge ● Enabled cross parameter truncate on data update GWC 1.12 GS 2.12 Kevin Smith Boundless MapStory 

Manage and configure “blob store” used to hold cached tiles, and “gridsets” to define tile grids associated with a spatial reference system. GeoWebCache REST API - new endpoints! 2.13 Boundless Torben Barsballe Boundless 

Styling Your cartographic tailor 

Labelling improvements ● Kerning on by default (adjusts spacing between chars, e.g. Check space between T and r in Trimble) ● Underline and Strikethrough ● Char and word spacing control ● Labelling border of polygon (instead of the centroid) 2.11 2.12 Andrea Aime Nuno Oliveria Community/Geoinfo/ OpenGeoGroep 

Determining a good location for a label can be tricky. Use of maxDisplacement indicates how far a label is allowed to move ● Previously we searched in a circular area for a good location ● Now you can supply your preference using displacementMode Labelling improvements 2.13 Nikolaos Pringouris 

● Allow using SVG as shapes for marks ● Filling and stroking can be controlled from SLD SVGs as fillable/strokable marks 2.14 Andrea Aime GeoSolutions Community file://firestation.svg #FF0000 32 

● JSON representation of styling ○ More limited than SLD/YSLD/CSS ● Works well with vector tiles ○ Cross platform styling (OpenLayers, MapBoxGL) ● Work in progress: ○ Currently a GeoTools community module ○ Should package and go to extension if we get time! MapBox Style Community Module 2.12 David Vick Boundless Boundless Suite MapBox Style in GeoServer and OpenLayers 

● Usage of units for more readable scale dependencies ● LessCSS functions to alter colors ● Convenient syntax to use env variables, @varName ● Much faster CSS -> SLD translation CSS improvements 2.12 Andrea Aime Community [class = 'major'][@sd < 25M] { [@scale > 3M] { mark: url('./symbols/place/place-6.svg'); mark-mime: 'image/svg+xml'; label-anchor: 0.5 0; label-offset: 0 2 }; label: [name]; font-size: [interpolate(@sd, 400k, 15, 25M, 12)]; font-color: lighten(red, 10%); } 

● ChannelSelection allows for env variables now ● Build pseudo-color styles with a default band layout ● Change the selected bands in GetMap request ● No need to prepare tens of different styles ● What if you want to do band math? You wait just 1 minute! Dynamic channel selection 2.14 Andrea Aime GeoSolutions DLR ...&env=r:4;g:3,b:2 ...&env=r:8;g:11,b:4 Pseudo color Vegetation analysis 

Web Processing Service When the going gets tough the processes get going 

Unleash map algebra with Jiffle ● Powerful and fast map algebra language ● Can be used as a rendering transformation ● Example, computing NDVI on the fly: 2.14 Andrea Aime GeoSolutions Bayer nir = src[7]; vir = src[3]; dest = (nir-vir)/(nir+vir); Sentinel 2 Jiffle script On the fly NDVI index display 

WPS Download (Community module) ● Download large raw rasters ● Download large raw vector ● Download large static maps with remote maps inclusion ● Build time based animations ● Allows usage of async calls for expensive map rendering and long animation building 2.13 GeoSolutions EUMETSAT 

CSV input/output for WPS ● Allows the input and output of CSV for use in WPS processes ● This will lead to GeoTools CSV Datastore being upgraded to community (and hopefully to supported) 2.12 Ian Turton Astun RnD 

Configuration and management 

User Interface - Autocompletion Entering in URLs for data files has been improved with autocomplete ● Entering URLs for data files, will scan the path suggest existing files ● Long lists of stores or layers also feature autocomplete 2.13.0 Andrea Aime Community 

User Interface - Raster Parameters Filling in raster layer, parameters is now easier and less error prone ● checkboxes ● dropdowns 2.13.0 Andrea Aime Community 

Full-screen style editor Andrea & Torben Community 2.14 

External graphic chooser in style editor Niels - ● Security fixes being added to supported versions only ● Please upgrade your GeoServer installations! 2.14 

Color picker in style editor Andrea Aime Community You know…. just in case you don’t remember the hex code of the color you want! 2.14 

● Label export, most shared configurations exported ● Some in the works (word/char spacing, strikethrough, polygon border labelling) ● Some changes needed in GeoServer SE 1.1 parser too If you prefer point and click: QGIS 3.0 style export 2.12 Andrea Aime GeoSolutions OpenGeoGroep 

Isolated Workspaces Workspaces are used to partition what is published for ease of management: ● A workspace has a namespace (used to keep XML content from conflict) ● Workspace published as a web service Problem: ● INSPIRE standard requires the use of a specific namespace ● Cannot use same namespace, preventing reuse of INSPIRE namespace Isolated workspace: ● Allows one workspace to publish the common layers ● The remaining workspace (each one marked isolated) can reuse these common layer Allows the same application schema to be published from multiple workspaces, each mapped onto different datasets 2.13.0 Nuno Oliveira GeoSolutions SYKE 

JDBCConfig and JDBCStore (Community) Use a database, rather than data directory, for clustering: ● GeoServer “Catalog” configuration ● GeoServer support files (styles, icons, fonts, config files) Work done for 2.13: ● Reduce number of database queries to improve performance ● Consistently log configuration queries for analysis 2.13.0 Niels Charlier Steve Ikeoka - 

Search Where did I put that satellite image again?? 

OpenSearch for Earth Observations ● Recent addition to OGC protocol for search of earth imagery ● Simpler alternative to CSW with ebRIM ● Two steps search ○ First find collection of similar products (by satellite/sensor) ○ Then search products in it (by other attributes, e.g., cloud cover, off nadir) ● Keeps database of searchable metadata ● Links to OGC services providing said data ● Allows downloading ISO/O&M metadata 2.12 GeoSolutions DLR/EVO-ODAS 

Help us help you 

User List Participation ● Answering users questions relies on a low number of people Action: ● We are sending reminder on effective use of the user list on subscription and at the bottom of each mail ● Community building activity - remind developers about the definition of “supported” (not only reviewing pull requests, also answering user questions, used to be obvious, but it’s not obvious to devs hired into open source) 

● Keep exploit details out of issue report ● Mark the issue as a vulnerability. ● Be prepared to work with Project Steering Committee (PSC) on a solution ● Keep in mind PSC members are volunteers and an extensive fix may require fundraising / resources If you are not in position to communicate in public please consider commercial support, contacting a PSC member, or reaching us via the Open Source Geospatial Foundation at [email protected]. In case you stumble into a vulnerability: Responsible Disclosure 

● Bug stomp introduced in 2016 ○ Relying on volunteer time not working out ○ allowed developers to reserve time ● Moved to fixed schedule in 2017 ○ Arranging day each month too random ● Last Friday of each month ○ Check blog post for tips on participation You can join and help, too! Standing “last friday of the month” bug stomp 

Thanks!
