Configuration

Style editor

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

Need to mass-configure layers? Importer!

GUI and REST

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● Asynch 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

Vector data sources

Files files, many little files

(OGR)

SQL

Everybody loves curves● Read curved geometries from Oracle and PostGIS, paint them, GML output

them, linearize everywhere else

Old but gold!Simple Mosaic

ArcGrid

Fully configured Mosaic (custom schemas, attributes,

filtering, sorting, custom storage)

Going native

GDAL 2.x (NITF files)

Fast JPEG2000

Maps, mapseverywhere!

Basic maps

Samples from IGN (using SLD)

OSM? Yes OSM! (With CSS this time)

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 forsmooth reprojection

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”

Integrated tiles cache

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

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

Deliver data

WFS and WCS

● Download vector data● Filter, reproject, join, page

● Download raster data● WCS 2.0, a protocol humans can

understand

CQL

POP_EST <= 5000000 AND POP_EST >100000

A light weight “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

Process!

● Analyze, publish, transform on the fly, access local data

Integrated WPS

Think small

● Small is useful● BBOX for filtered datasets● Aggregation processes, provides

datasets for building charts (group and count)

● Clip and ship● Build animations

Think big!

● Start remote processing nodes, track their progress

● Register the result as a GeoServer layer for preview before download

Rendering transformations:

process and render at the same time
