Parallel activity EVO-ODAS
- Coordinated by DLR - German Aerospace Center
- ESA funded project
- Objective to improve the acceptance of online EO data access services and standards and to promote their evolution and diffusion
- Overlapping with Testbed-12 e.g. multidimensional data, security, etc.
- wiki.services.eoportal.org/tiki-index.php?page=EVO-ODAS
NA001 WCS new profile 1
- Extend EO-WCS support for 3D space and 1D time data in EOxServer
EOxServer in brief
- MIT-style license
- Closely following the concepts of WCS & EO-WCS
- Implementing WCS, EO-WCS, WMS, EO-WMS, WCS-T, WPS, OpenSearch, etc.
- Based on Open Source stack including Python, Django, MapServer, GDAL, etc.
- Included on OSGeo Live
- eoxserver.org
- github.com/EOxServer/eoxserver
NA006 WMTS for time-varying layers
- Extend temporal WMTS tile assembly in MapCache - EOX
- Implement logic to avoid requesting empty tiles in MapCache - EOX
- Participate in OGC WMS.SWG - EOX
- Support for communication of empty areas in GeoServer WMS/WMTS - GeoSolutions
- Improved Support for TIME and other dimensions in GeoServer WMS/WMTS - GeoSolutions
MapCache in brief
Suite- MIT-style license
- Stable release 1.4
- Tiling Library with Apache, FastCGI, Nginx, and Node frontends
- Native code: Fast and Efficient
- mapserver.org/mapcache/index.html
- github.com/mapserver/mapcache
NA007
- Add support for WMS extensions of ncWMS in EOxServer e.g. color scales in GetMap requests or GetTimeseries request type - EOX
- Add support to filter WMS Capabilities e.g. XPath in EOxServer - EOX
- Add support for further WMS extensions of ncWMS in EOxServer - EOX
- Enhance NetCDF-CF metadata handling in EOxServer - EOX
- Dynamic ColorMaps Support in GeoServer WMS - GeoSolutions
- Improved GetLegendGraphic in GeoServer WMS - GeoSolutions
- Simplified Harvesting of NetCDF-CF files in GeoServer - GeoSolutions
- Improved GetCapabilities for large number of datasets (possibly using XPath) in GeoServer - GeoSolutions
WMS in EOxServer
- Based on
- Full support of EO-WMS including time dimension, outlines, bands, etc.
- Masking & mosaicing
Dynamic colormaps support in GeoServer
- Collect statistisc from data (e.g. histogram)
- Create a color map on the fly based on the statistics and a named color map type
- Based on GeoServer own SLD extension called "Rendering transformations" (aka "apply me a WPS process on the fly before rendering data")
GetLegendGraphics for dynamic colormaps
- GetLegendGraphics needs to learn about dynamic colormap
- Display the right colormap, display the right values on the side
LSA - Big Data Tiles
- Contributions to & review of Big Data Database ER
- Big Data Tile Database Implementation
- Evaluate PostgreSQL as alternative to SQLite in GeoPackage
- Implement database generation, dump, and restore scripts for PostgreSQL as alternative to SQLite in GeoPackage
