geotiff2json
This package allows to parse GeoTIFF files into a run-lengh-encoded JSON array of height values. The package is primarily aimed at converting LIDAR data into a pointcloud.
Usage
Here's an example that converts file.tif
into an RLE value array and writes it to disk as points.json
:
var geotiff2json = fs =
The output file's content will look similar to this:
Note: The linebreaks and whitespace have been added for better readability, the file won't contain those to reduce size.
These values are in fact value pairs.
- The first value of each pair is the y-coordinate of the point.
- The second value of each pair is the number of times this y-coordinate is repeated.
So in the example above, the y-value 100
shall be repeated 10
times, the y-value 132
shall be repeated once and so on..
