geotiff.js is a small library to parse TIFF files for visualization or analysis. It is written in pure JavaScript, and is usable in both the browser and node.js applications.
Would this be helpful? Internally, writeArrayBuffer would call another function that creates the <GDALMetadata> xml file and adds that as a GDAL_METADATA tiff tag to the output file.
import { writeArrayBuffer } = "geotiff";
writeArrayBuffer(data, {
// an array of stats objects
// each object represents that stats for that band (by array index)
gdalStats: [
{
STATISTICS_MAXIMUM: 255,
STATISTICS_MEAN: 72.031078729883,
STATISTICS_MINIMUM: 0,
STATISTICS_STDDEV: 38.825421707699,
STATISTICS_VALID_PERCENT: 100
},
// you can also pass in statistics as strings
// getGDALMetadata returns raw strings
// and a user might want to return high-precision numerical strings
// that are more precise than what JavaScript support
{
STATISTICS_MAXIMUM: "255",
STATISTICS_MEAN: "113.60373423227124325",
STATISTICS_MINIMUM: "0",
STATISTICS_STDDEV: "38.825421707699",
STATISTICS_VALID_PERCENT: "100"
}
]
})
