2. ncWMS Provides data visualisation over the web
Uses WMS standard to expose data directly from NetCDF (+ other data formats)
Useful for quick and simple visualisation
Based on open standards
Modular, so libraries can be used for other data manipulation + visualisation applications

3. ncWMS2

4. Godiva3 ncWMS enhances the WMS standard with data-specific operations
Godiva3 is a web client which uses these ncWMS extensions to provide access to:
Colour scale range selection (scale limits, palette, linear/logarithmic, out-of-range values)
Non-geographic plots (time series, vertical profile, along-path, vertical section)
Animation
Export to PNG / Google Earth / CSV

5. ncWMS

6. Demo / Workshop
Wednesday - Demonstration of ncWMS from a user perspective
Thursday – Workshop on installing ncWMS on a server and administering it to serve your own data.

7. CovJSON – Why and what
Formats and tools for scientific data are not always easily usable in web browsers
NetCDF, HDF, GRIB, GeoTIFF, ...
Complex, binary, monolithic, desktop-oriented
We often resort to images when building apps
CovJSON brings scientific data within the reach of more Web and app developers
Lightweight and efficient
Easy to produce and consume
TODO: use material from abstract – limitations of curent ways of building web apps, need for data format that is rich enough to support EO data in various kinds, and easy enough to use in web applications and mobile apps.
Use power of browser – reduce need to deploy algorithms server-side, which adds complexity

8. CovJSON – Features Spatial, temporal, other dimensions
Gridded and non-gridded data
n-Dimensional data
Continuous and categorical data
Scalable through tiling
Internationalisation
Partial conversion to RDF is possible
Data, not images!
Enough information to enable rich web applicaitons and analytics

9. Technology Demonstrator Portal
Load, display, modify, compare datasets
CovJSON, GeoJSON, JSON-LD, WMS, ...
CKAN integration via GeoDCAT-AP feeds
Data, not images!
Enough information to enable rich web applicaitons and analytics

10. CovJSON Demo (Wednesday) Hands-on session (Thursday)
Dynamic visualisation of diverse datasets
Land cover reclassification, statistics & subsetting
On-the-fly CRS reprojection
Hands-on session (Thursday)
Explore the format in the playground
Write your own CovJSON documents
Serve CovJSON from a web server
Visualise CovJSON in web browsers in 5min
Data, not images!
