Workflow

Generally speaking, all the instructions on how to proccess raw data into a value-added product are written in a run file within a project directory (e.g. /projects/Halifax_AIS). However, note that each run file needs to point to a set of basemap/grid files, which are done previously and stored elsewhere (e.g. /grids/Maritimes/ancillary).

Even though not all steps are required in every project, the run file may include the following instructions:

• Convert original data into “Standard NC files”: bulk_convert_to_nc

• Filter data

  • Filter data to include only a narrow domain: spatial_filter
  • Filter data to include specific dates

• Project “pings” onto grid: gridder
• Merge multiple grids: grid_merger
• Make a map: map_density
• Save grid as shapefile: mergedgrid_to_shp
