N_geom_data* N_alloc_geom_data ( void )

Allocate the pde geometry data structure and return a pointer to the new allocated structure.

Returns: N_geom_data *

void N_free_geom_data ( N_geom_data * geom )

Release memory of a pde geometry data structure.

Parameters

geom	N_geom_data *

Returns: void

double N_get_geom_data_area_of_cell	(	N_geom_data *	geom,
		int	row
	)

Get the areay size in square meter of one cell (x*y) at row.

This function works for two and three dimensions

geom	N_geom_data *
row	int

Returns: area double

N_geom_data* N_init_geom_data_2d	(	struct Cell_head *	region,
		N_geom_data *	geodata
	)

Initiate a pde geometry data structure with a 2d region.

If the projection is not planimetric, a double array will be created based on the number of rows of the provided region storing all computed areas for each row

Parameters

region	sruct Cell_head *
geodata	N_geom_data * - if a NULL pointer is given, a new structure will be allocatet and returned

Returns: N_geom_data *

N_geom_data* N_init_geom_data_3d	(	G3D_Region *	region3d,
		N_geom_data *	geodata
	)

Initiate a pde geometry data structure with a 3d region.

If the projection is not planimetric, a double array will be created based on the number of rows of the provided region

Parameters

region3d	G3D_Region *
geodata	N_geom_data * - if a NULL pointer is given, a new structure will be allocatet and returned

Returns: N_geom_data *
