wapor_extract.Rd

This function can be used to extract and summarise the data output by the wapor_indices function on a polygon basis. The data is returned as a list object with several tables in long-format. These objects are:

  • Land Cover Statistics (lcc_stats): breakpoint, median land use, modal land use

  • Land Cover Frequency (lcc_freq): the averaged frequency of occurence for selected land cover classes

  • Indices (indices): Averaged yearly statistics of the raw parameters as well as LP1_global and LP1_yearly

  • Double Season: Class specific occurence of double seasons per year

  • Double Season Difference: Difference in number of double season in pre- and post epoch

  • Epoch Differences: Differences in productivity for raw parameters

  • Trends: Estimates and p-values of a linear trend per parameter
