Create inputs for BRAMS-SPM. The inputs consist of a data-frame or a list of data-frames with daily emissions (mol/day), lat, long. Also, including a functions describing the hourly profile.

to_brams_spm(sdf, epsg = 4326)



Grid emissions, which can be a SpatialPolygonsDataFrame or polygon grid class sf' including the hourly emissions in mol/h for 24 hours. The object can also be a list of objects SpatialPolygonsDataFrame or Spatial Features polygon grid class 'sf'.


Coordinate reference system, e.g: "4326". Used to transform the coordinates of the output.


data-frame of daily gridded emissions, lat, long and a message with function.


When the input is class 'Spatial', they are converted to 'sf'. If the input is a data-frame, the output is a data-frame. If the input is a list, the output is a list.
