Weekly Report 1

What did you get done this week?

  • I refractored PlanetSasha? code and make it more like an API
  • Created UI classes for handling Qt's Gui widgets:

SashaMainWindow?, NavigationWindow?, MapWindow?,
GpsWindow?, GraphWindow? PanToolBox?, RollToolBox?, PitchToolBox?

  • Since these classes are handling Qt's QTabWidget & QDockWidget mainly, porting was easy.
  • Slots has been moved in various places as the single file code style has been abandoned.
  • Started some code for generating python code at runtime based on PyOSSIM App.

What do you plan on doing next week?

  • I will finish PyOSSIM app generator next week ready to be tested.
  • Understand the code level differences when talking with geonetwork,geoportal and friends
  • Start coding of PlanetSasha? module for fetch getCapabilites

Are you blocked on anything?

  • As of now nothing


Weekly Report 2

What did you get done this week?

  • Code cleanup was the major work done this week.
  • ossim apps executed from PlanetSasha? now uses pyossim.
  • To run an ossim application there must be a python wrapper on top of pyossim for the c++ app.
  • If no wrapper is found it will issue a warning and spawn a process.
  • I had also added an option to spawn seperate process for every ossim application.
  • Updating pyossim code to work with ossim trunk.

What do you plan on doing next week?

  • I will start implementing the fetch module for USGS Tredds/Geo?-Portal services.
  • Extending preferences class for handling settings for fetch module such as caching.
  • Start with netcdf part if everything comes clean before thursday.

Are you blocked on anything?

  • Nothing. I couldn't implement fetch module this week which I can patch up with some extra hours before monday.


Weekly Report 3

What did you get done this week?

  • Implemented the nc fetch/import moudle.
  • As per plan caching mechanism was scheduled for week #3 but I swapped it with week #5
    because gui is needed to define some caching parameters such a bbox that comes from an interactive map.
  • Moved SDI style of PlanetSasha? to MDI. It used a tabbed way and takes too much time
    to load all tabs(actually modules) during startup. MDI seems neater for us.
  • Added a ossim app runner interface for planetsasha.

What do you plan on doing next week?

  • I will work on the netcdf parser in PlanetSasha?. It will parse .nc file from geocatalog and save metadata.
  • Bounding box selection is now a simple image. Next week I plan to make it interactive as shown in geonetwork.

Are you blocked on anything?

  • Nothing.


Weekly Report 4

What did you get done this week?

  • Main work was on parsers. OWSLib can handle openDAP, WCS, WMS services
    but Thredds catalog may not have them all the time.
  • I had made a parser for such Thredds catalog for getting netCDF files.
  • Its based on simple xml and had a standard way but since xml parsing has a lot of boundary
    conditions to be checked it took most of my time.
  • Parser has been made reclusive and it has X levels in a Y sub-level. X and Y both being big numbers.
  • I had also modified the gui for import, using a QWizard instead of a single QWidget.
  • Apart from that I also tried with some IPython code which can visualize a .nc dataset
  • Bounding box selection is still simple and making it interactive was planned for this week.
  • But It seems interactive bounding box have less priority after discussing with my mentor

USGS Thredds which doesn't have any OGC services cannot be queried and no lib exists.
Some gui elements are optional for Thredds without any OGC Service (WMS/WCS/CSW).

What do you plan on doing next week?

  • I will continue the work Thredds catalog.
  • Now I had two pieces separately. NC viewer(IPython) and data importer.
  • I plan to merge both inside PlanetSasha? and make that module complete.

Are you blocked on anything?

  • Nothing. But parser making taking a lot of time than expected


Weekly Report 5

What did you get done this week?

  • Auto switching to custom planetSasha fetch method for Thredds catalog with no OGC services enabled.
  • Created a new ui for viewer which uses matplotlib.
  • When a netCDF source listed in the import is selected it is added to source tree in the viewer ui.
  • Import allows multiple selection of .nc files which is important because fetching takes time is longer in some cases.
  • matplotlib's basemap visualize the selected data source from the source manager.

What do you plan on doing next week?

  • Update import ui for time selection, interpolation etc.
  • Add provision to view metadata netCDF dataset.
  • Instead of fetching every time a simple xml (custom) should created locally and used in later parsing.
  • PlanetSasha? will check for xml file in local system using custom naming convention (date-time-beautified(url)).
  • Another alternative I was planning to use is add sqlite db (data_cache.db) for this purpose (can store url, date, time etc..).
  • The local xml should be removed and created again only if the force option is selected and fetch comes from server.
  • Using this caching technique user's will be able to fetch the .nc files and save time from redundant parsing of Catalog.

Are you blocked on anything?

  • Fetcing the catalog through recusrive parsing taking a lot of time making a delay in debugging and testing


Weekly Report 6

What did you get done this week?

  • worked on mapwindow NetCDF Viewer. added controls to select time period and interpolation
  • worked on import module. single long fetch is removed.
  • USGS Thredds catalog fetch mimics that of browser and catalog tree nodes are expanded on user command. This saves a very large amount of time since each fetch takes a couple of seconds and there is no point in creating local xml files to avoid parsing. However .nc files may need caching.
  • fixed matplotlib issues when plotting inisde PyQt?.
  • added progressbar to monitor matplotlib's plotting.

What do you plan on doing next week?

  • I am planning to add multithreading support in the mapwindow.
  • matplotlib operations must be done in a seperate thread detached from ui.
  • I will work on progressbar updation logic based on threading mechanism
  • If everything comes clean by wednesday I will work on pyossim-planetsasha part

Are you blocked on anything?

  • Nothing

  • My plan is to get netcdf as numpy and then load it using pyossim-numpy module.
  • finish xml parsing for running ossim apps through planetsasha.

Are you blocked on anything?

  • Nothing


Weekly Report 10

What did you get done this week?

  • Added a new functionality which can load ossim apps based on an xml file ossim-info has been used for testing. but currently xml are not generated by code each app can generate a properties xml and planetsasha's ossimwindow reads this to create and run app from gui

What do you plan on doing next week?

  • continue work on netCDF -> ossim via planetSasha

Are you blocked on anything?

  • Nothing

  • created extraction of data from netCDF after processing
  • vector generated is in shapefile using OGR and can be visualized in planet or grass

  • adding an animate button to send the processed netcdf to planet
  • sending data to grass using pygrass. I am not sure about v.to.rast needed for sending
    Default is sending vector data to grass.
