Diana - roadmap [wiki.met.no]

diana:tasks

This is an old revision of the document!

Diana are now using proj4 to handle projection, but there are some issues left:
- Remove all reference to the old projection-library milib
- There are still some problems when plotting spherical earth data on a map with spheroidal reference surface

Use The fimex library to read field data
- Read Felt-format, NetCDF (including ncml), Grib(1&2), and Wdb] * FieldFunctions will use standard_names (cf) * Definitions will be moved from the setupfile to gui * reference time * plot type (contour, wind arrows, values etc) * All fields from a data source should be available as 1-dimensional plots without any setupfile definitions * Plot definitions in the setupfile will be used to define: plotname, default options, multi-dimensional plots etc ==== Web Map Services ==== * producing WMS-layers * bdiana can produce maps for WMS servers, but this functionality needs improvment * displaying WMS-layers * Diana should be able to display maps from WMS-servers ==== Vertical cross-sections ==== * New option: Min/max value * Find min/max value in the current cross-section * Mark the min/max positions at the plot * Write max value and position below the plot * Write min value and position below the plot * QuickMenu * Include Vertical cross-section plots in QuickMenus ==== Polygons, points etc ==== * Data from shape, ascii, qsocket * Time dependent/independent * Datatypes * polygons(coordinates, text, colour etc) * points (coordinates, text, url, colour, marker etc) * Texts available on the map or in separate textbox * Editable * Priority levels, just plot the most important info (?) ==== Raster images ==== * Use the field interface * Select channel mixing in the gui ==== Observations ==== * Read observations from url * More general plotting, all parameters available * Move parameter definitions to the setupfile * Possible to mix data from different sources (metadata + data) ==== Stations ==== * StationPlots are shown as selectable markers on the map * They are used for: * Vertical profiles * Info from QSockets (tseries, mimage, qed) * Some new features are needed: * List of stations (positions, some action) from asciifile/url * New action: showing an url * [[tasks:stations|more...

All information available from ascii files should also be available from http
- setupfile, ascii-obs, maps, product definitions

Should diana use Qt's Graphics View Framework?
- Use Qt's Graphics View Framework when editing maps (draw polygons, points, etc)?
- Use Qt's Graphics View Framework for all plotting?

Questions:
- Is it fast enough?
- Can the Graphics View plot all layers available i diana today?
- What about bdiana?

Advantages
- Advanced polygon drawing
- Possible to write directly on map
- Advanced GraphicsItem handeling
- Might solve PostScrips issues?
- Might solve bdiana X-display issues?
