create_raster: Create Raster Element

In CVPIA-OSC/EMLaide: Provides functions for building EML metadata for EDI's data repository

Create Raster Element

Description

This function creates all the required elements for a spatialRaster section of an ELM document.

Usage

create_raster(
  file_name,
  file_description,
  attribute_list,
  physical,
  spatial_reference,
  horizontal_accuracy,
  vertical_accuracy,
  cell_size_x,
  cell_size_y,
  number_of_bands,
  raster_origin,
  rows,
  columns,
  verticals,
  cell_geometry
)

Arguments

file_name	The name of your raster file
file_description	A short description of your file
attribute_list	A list of all the columns on your datatable. Use create_attribute to generate this attribute list and see the documentation for create_attribute for more information.
physical	A list of the physical descriptions of your file. Use create_physical to generate this physical list and see the documentation for create_physical for more information.
spatial_reference	This is the name of a predefined coordinate system. The acceptable values for spatial_reference can be found at EDI Schema.
horizontal_accuracy	The accuracy of horizontal locational measurements within the data.
vertical_accuracy	The accuracy of vertical locational measurements within the data.
cell_size_x	The width of the cell in the x direction.
cell_size_y	The width of the cell in the y direction.
number_of_bands	The number of bands in the image.
raster_origin	The corner location of the pixel it should have the minimum x and y values
rows	Max number of raster object along the y-axis
columns	Max number of raster objects along the x-axis
verticals	Max number of raster objects along the z-axis
cell_geometry	Geometric representation of the cell's content
parent_element	A list to append spatialRaster to
