classify_veg_transitions: Classify vegetation transition depths

In WDNR-Water-Use/CSLSlevels: CSLS Lake Level Analysis

Description

Given the name of the lake of interest and shallow/deep limits for vegetation classes, this defines transition depths between classes of vegetation. It is not necessary to provide the shallowest depth of "upland" or the deepest depth for "submergent" if these correspond with the maximum depth of the lake. If desire depths in ft, be sure to set depth_to_meters to FALSE and provice countour_interval in feet. Assumes deepest and shallowest depths are always provided in ft.

Usage

classify_veg_transitions(
  lake,
  deepest = data.frame(upland = -1, inland_beach = 1.6, emergent = 7, floating = 10),
  shallowest = data.frame(floating = 5, submergent = 1.6, emergent = -1, inland_beach =
    -1.6),
  contour_interval = 0.1,
  depth_to_meters = TRUE
)

Arguments

lake	name of lake to analyze, e.g., "Long". Must be present in both CSLSlevels::csls_levels and CSLSdata::lake_levels.
deepest	list with deepest depth each vegetation class can tolerate (ft). If depth_to_meters is TRUE, these will be converted to meters. If deepest not provided for "submergent", assumed to be the max depth of the lake.
shallowest	list with shallowest depth each vegetation class can tolerate (ft). If depth_to_meters is TRUE, these will be converted to meters. If shallowest not provided for "upland", assumed to be the negative max depth of the lake.
contour_interval	interval of contours to use when creating relationship, same units as desired transition depths data frame. Defaults to 0.1.
depth_to_meters	defaults to TRUE, indicating transition depths will be in meters and deepest and shallowest should be converted from feet to meters. .

Value

transitions, a data frame with the following columns:

depth	depth of transition point (meters)
class	name of vegetation classes present at/deeper than this depth
