Filter by Interval ​

Data is collected in regular intervals. Currently bwi2012, ci2017 and bwi2022 are available. The interval data is stored in the interval_name columne of the inventory_archive.plot table. The interval_name is used to identify the data of a specific interval.

  • bwi2012: Kohlenstoffinventur in 2012
  • ci2017: Kohlenstoffinventur in 2017
  • bwi2022: Bundeswaldinventur in 2022

Read by Interval ​

To read data from a specific interval, you can use the interval_name column in the inventory_archive.plot table. The following example shows how to query data for the ci2017 interval.

INFO

Every request lower or equal plot table should include the filter interval_name=eq.XXX to ensure that only data from the selected interval is returned.

txt
curl -X GET "https://ci.thuenen.de/rest/v1/plot?interval_name=eq.ci2017" -H "Accept-Profile: inventory_archive" -H "apikey: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoiYW5vbiIsImlzcyI6InN1cGFiYXNlIiwiaWF0IjoxNzQ1NzkxMjAwLCJleHAiOjE5MDM1NTc2MDB9.hXiYlA_168hHZ6fk3zPgABQUpEcqkYRMzu0A5W5PtYU"

This will return all plots that are part of the ci2017 interval.

Comparing Intervals ​

To compare cluster data from different intervals, you can use the interval_name column in the inventory_archive.cluster table.

The following example shows how to query a specific cluster (cluster_name=eq.5207) for the bwi2012 and ci2017 intervals.

txt
curl -X GET "https://ci.thuenen.de/rest/v1/cluster?cluster_name=eq.5207&select=*,plot(*,tree(*),deadwood(*),regeneration(*),structure_lt4m(*),structure_gt4m(*),edges(*),plot_landmark(*),position(*),subplots_relative_position(*))&plot.interval_name=in.(bwi2012,ci2017)" -H "Accept-Profile: inventory_archive" -H "apikey: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoiYW5vbiIsImlzcyI6InN1cGFiYXNlIiwiaWF0IjoxNzQ1NzkxMjAwLCJleHAiOjE5MDM1NTc2MDB9.hXiYlA_168hHZ6fk3zPgABQUpEcqkYRMzu0A5W5PtYU"

This will return the cluster data for the specified cluster, including 8 plots. 4 plots are from the bwi2012 interval and 4 plots are from the ci2017 interval. The data is structured in a way that allows you to compare the data from both intervals.
