NAME

v.gsflow.mapdata - Upload data to PRMS data

KEYWORDS

vector, import, hydrology, GSFLOW

SYNOPSIS

v.gsflow.mapdata

v.gsflow.mapdata --help

v.gsflow.mapdata map=name [vector_area=name] [vector_points=name] [raster=name] [dxy=string] [column=string] [from_column=string] [attrtype=string] [--help] [--verbose] [--quiet] [--ui]

Flags:

--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

map=name [required]: GSFLOW vect: HRUs, MODFLOW grid, gravres, segments, or reaches; Or data source for direct OGR access
vector_area=name: Input vector area (polygon) data set (e.g., geologic map); Or data source for direct OGR access
vector_points=name: Input vector points data set (e.g., field surveys at points); Or data source for direct OGR access
raster=name: Input raster gridded data set (e.g., gridded soils data); Name of input raster map
dxy=string: Cell size for rasterization of vector_area, if needed; Default: 100
column=string: Column to which to upload data (will create if doesn't exist)
from_column=string: Column from which to upload data (for vector input)
attrtype=string: Data type in column; user may treat int as float; Options: int, float, string

DESCRIPTION

v.gsflow.mapdata allows the user to add attributes from any raster or vector (area or point) data set to a GSFLOW set of HRUs, MODFLOW grid cells, gravity reservoirs, stream segments, or stream reaches. It does so by using either an averaging or a nearest-neighbor approach, depending on the type of both the data source geometry (raster, vector area, vector point) and, if it is a vector, the data source in the column (integer, string (varchar), or float (double precision)).
Nearest-neighbor (v.distance,) is used for:
Vector point data
Vector area data in which the data type in the column that is queried is integer or varchar
An average (v.rast.stats,) is used for:
Raster data
Vector area data with data in the column that is queried that is of "double precision" type
