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.
Here's an example that converts
file.tif into an RLE value array and writes it to disk as
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..
If you find a bug or a problem or data that doesn't parse correctly, even though it should, please [report an issue here](https://github.com/avgp/geotiff2json/issues/new].
In case you found a GeoTIFF that doesn't parse correctly, please attach a link to the file or attach it to the issue directly.
If you have improvement suggestions, feel free to fork this repository and submit a pull request!
Thank you for your help and support!
