Struct BasicRasterInfo

pub struct BasicRasterInfo {
    pub geo_transform: [f64; 6],
    pub size: (usize, usize),
    pub epsg_code: u32,
    pub no_data: Option<f64>,
    pub n_bands: usize,
}

Basic metadata extracted from a single GDAL dataset open.

Consolidates the 6 separate Dataset::open calls in builder.rs (get_resolution, get_geotransform, get_extent, get_epsg_code, get_na_value, get_image_size) into a single dataset open.

Fields

geo_transform: [f64; 6]

GeoTransform (x_ul, x_res, x_rot, y_ul, y_rot, y_res)

size: (usize, usize)

Image size in pixels (cols, rows)

epsg_code: u32

EPSG code (0 if unknown)

no_data: Option<f64>

No-data value (None if not set)

n_bands: usize

Number of raster bands

Implementations

impl BasicRasterInfo

pub fn resolution(&self) -> ImageResolution

pub fn image_size(&self) -> ImageSize

ImageSize struct derived from size tuple.

pub fn na_value<T: RasterType>(&self) -> T

No-data value cast to type T, or T::zero() if not set.
