monitoring_plots

0 rows


Description

Regions within planting subzones that can be comprehensively surveyed in order to extrapolate results for the entire zone. Any monitoring plot in a subzone is expected to have roughly the same number of plants of the same species as any other monitoring plot in the same subzone.

planting_subzone_id int8 19 null
planting_subzones.id monitoring_plots_planting_subzone_id_fkeyC

Which planting subzone this monitoring plot is part of.

full_name text 2147483647 null
created_by int8 19 null
users.id monitoring_plots_created_by_fkeyR

Which user created the monitoring plot.
created_time timestamptz 35,6 null

When the monitoring plot was originally created.
modified_by int8 19 null
users.id monitoring_plots_modified_by_fkeyR

Which user most recently modified the monitoring plot.
modified_time timestamptz 35,6 null

When the monitoring plot was most recently modified.
boundary geometry 2147483647 null

Boundary of the monitoring plot. Coordinates always use SRID 4326 (WGS 84 latitude/longitude).
permanent_cluster int4 10 √ null

If this plot is a candidate to be a permanent monitoring plot, its position in the randomized list of plots for the planting zone. Starts at 1 for each planting zone. There are always 4 plots with a given sequence number in a given zone. If null, this plot is not part of a 4-plot cluster but may still be chosen as a temporary monitoring plot.
permanent_cluster_subplot int4 10 √ null

If this plot is a candidate to be a permanent monitoring plot, its ordinal position from 1 to 4 in the 4-plot cluster. 1=southwest, 2=southeast, 3=northeast, 4=northwest.
is_available bool 1 true
size_meters int4 10 null

Length in meters of one side of the monitoring plot. Plots are always squares, so for a 30x30m plot, this would be 30.
planting_site_id int8 19 null
planting_sites.id monitoring_plots_planting_site_id_fkeyC
