lake_raster: CSLS lake rasters
In WDNR-Water-Use/CSLSdata: WI DNR Central Sands Lakes Study Field Data

Description Usage Format Details Examples

Lake elevation rasters for each lake as exported from ArcGIS. Elevation information is a combination of Biobase sonar data (Pleasant) or point-intercept surveys (Long and Plainfield) plus LiDAR, for elevations above the lake level elevation on the date of each survey.

1	data(lake_raster)

A list with the following columns:

Pleasant: elevation raster for Pleasant Lake (m)
Long: elevation raster for Long Lake (m)
Plainfield: elevation raster for Plainfield Lake (m)

Raw raster data is processed in the data-raw/ subdirectory of this project with the function import_lake_rasters.R which is run by runall_cslsdata.R.

import_lake_rasters.R loads the lake rasters for CSLS lakes (as exported from ArcGIS) into a list, with no transformations of the data. These rasters are clipped to approximately the highest observed lake level (in 2019) plus a spatial buffer of 20m.
