val proximity : 
  ?options:string list ->
  src:(_, _) Band.t ->
  test:(_, _) Band.t ->
  unit

proximity ?options ~src ~test computes the pixel-by-pixel proximity between src and test.

val fill_nodata : 
  ?options:string list ->
  target:(_, _) Band.t ->
  mask:(_, _) Band.t ->
  float ->
  int ->
  unit

fill_nodata ?options ~target ~mask distance iterations will fill in target's missing data pixels. See GDAL's GDALFillNoData documentation for an explanation of the function parameters.

val generate_contours : 
  ?no_data:float ->

  ('v, 'e) Band.t ->
  Layer.t ->
  [ `fixed of float list | `interval of float * float ] ->
  unit

generate_contours ?no_data ?id ?elevation band layer contours will create contours from band, adding them to layer.

parameter no_data
will be used as the "no data" value if specified.

parameter id
specifies a field where an identifier for each contour written to layer.

parameter elevation
specifies a field where the elevation value for each contour is written.

parameter band
is the field to generate contours from.

parameter layer
is the layer where contour geometries will be written to.

parameter contours
specifies the contours to create. `fixed l will create contours for each value in l. `interval (start, step) will create intervals starting with start and step intervals past that.

val rasterize_geometries : 
  ?transform:'a Transform.t ->
  ?options:string list ->
  Data_set.t ->
  int list ->
  (Geometry.t * float list) list ->
  unit

rasterize_geometries ?transform ?options ds bands geometries burn will will rasterize geometries onto ds.

parameter ds
is the data set where output is written.

parameter bands
specifies the list of bands to update.

parameter geometries
is the list of geometries to burn in and the values to burn, one per entry in bands.

parameter transform
specifies the transformation to pixel/line coordinates. Not required if ds and geometries use the same coordinates.

parameter options
specifies rasterization options. See the documentation for GDALRasterizeGeometries for available options. Defaults to [].

raises Invalid_argument
if the length of the burn value list(s) do not match the length of the band list.

val rasterize_layers : 
  ?transform:'a Transform.t ->
  ?options:string list ->
  Data_set.t ->
  int list ->
  (Layer.t * float list) list ->
  unit

rasterize_layers ?transform ?options ds bands layers burn will will rasterize layers onto ds.

parameter ds
is the data set where output is written.

parameter bands
specifies the list of bands to update.

parameter layers
is the list of layers to burn in and the values to burn, one per entry in bands.

parameter transform
specifies the transformation to pixel/line coordinates. Not required if ds and layers use the same coordinates.

parameter options
specifies rasterization options. See the documentation for GDALRasterizeLayers for available options. Defaults to [].

raises Invalid_argument
if the length of the burn value list(s) do not match the length of the band list.
