FM.readDEM: Load Digital Elevation Model (DEM)

In FloodMapper: Cross-Scale Flooding Prediction under Heavy Precipitation

Description

After a model run is initiated, this function should be first executed to load DEM raster.

Usage

FM.readDEM(demfile, waterdepth = 0, waterdepthfile = "", rerun = FALSE)

Arguments

demfile	full file path of the DEM raster.
waterdepth	(OPTIONAL) a number represents initial surface water depth (unit: m) to be applied to all grid cells.
waterdepthfile	(OPTIONAL) full file path of the initial surface water depth raster (unit: m). If a raster file is specified, the model will use this raster to initialize the surface water depth.
rerun	OPTIONAL, assign TRUE if this is a rerun.
