phenodata 0.5.0

Introduction

For most acquisition tasks, you must choose from one of two different datasets: annual-reporters and immediate-reporters.

To improve data acquisition performance, also consider applying the --filename= parameter for file name filtering.

Example: When using --filename=Hasel,Schneegloeckchen, only file names containing Hasel or Schneegloeckchen will be retrieved, thus minimizing the required effort to acquire all files.

Install

If you know your way around Python, installing this software is really easy:

pip install phenodata --upgrade

Please refer to the virtualenv page about further recommendations how to install and use this software.

Data acquisition options:
  --source=<source>         Data source. Currently "dwd" only.
  --dataset=<dataset>       Data set. Use "immediate" or "annual" for --source=dwd.
  --partition=<dataset>     Partition. Use "recent" or "historical" for --source=dwd.
  --filename=<file>         Filter by file names (comma-separated list)

Direct filtering options:
  --years=<years>           Filter by years (comma-separated list)
  --station-id=<station-id> Filter by station ids (comma-separated list)
  --species-id=<species-id> Filter by species ids (comma-separated list)
  --phase-id=<phase-id>     Filter by phase ids (comma-separated list)

Humanized filtering options:
  --station=<station>       Filter by strings from "stations" data (comma-separated list)
  --species=<species>       Filter by strings from "species" data (comma-separated list)
  --phase=<phase>           Filter by strings from "phases" data (comma-separated list)

Data output options:
  --format=<format>         Output data in designated format. Choose one of "tabular", "json", "csv" or "string".
                            With "tabular", it is also possible to specify the table format,
                            see https://bitbucket.org/astanin/python-tabulate. e.g. "tabular:presto".
                            [default: tabular:psql]
  --humanize                Resolve ID-based columns to real names with "observations" and "forecast" output.
  --language=<language>     Use labels in designated language when using ``--humanize`` [default: english].
  --limit=<limit>           Limit output of "nearest-stations" to designated number of entries.
                            [default: 10]

Forecasting

Acquire data from observations in Berlin-Dahlem and München-Pasing and forecast to current year using grouping and by computing the “mean” value of the “Jultag” column:

phenodata forecast \
    --source=dwd --dataset=annual --partition=recent \
    --filename=Hasel,Schneegloeckchen,Apfel,Birne \
    --station-id=12132,10961 --format=string

Observations

Observations for species “hazel”, “snowdrop”, “apple” and “pear” at station “Berlin-Dahlem”, output texts in the German language if possible:

phenodata observations \
    --source=dwd --dataset=annual --partition=recent \
    --filename=Hasel,Schneegloeckchen,Apfel,Birne \
