Lossless Compression
The following command compresses a LAS point cloud to MrSID Generation 4 using lossless compression:
mrsidgeoencoder -i foo.las -o foo.sid ‑of mg4 ‑lossless
Setting a Compression Ratio
The following command compresses a LAS point cloud to MrSID Generation 4 using a 15:1 compression ratio:
mrsidgeoencoder -i foo.las ‑o foo.sid ‑of mg4 ‑cr 15
Compressing a Text File
The following command compresses a text file and maps the columns in the text file to fields in the output point cloud:
mrsidgeoencoder -i in.txt ‑o out.sid ‑tfc txyzi
The file above contains the following values: the GPS time, the X values, the Y values, and the intensity.
Creating a Flat Mosaic
The following command uses a mosaic list file to create a LiDAR point cloud mosaic:
mrsidgeoencoder -i mosaic.list ‑mos ‑o mosaic.sid
The file with a .list
extension is the mosaic list file. The following lines display the contents of a sample mosaic list file for a given set of georeferenced LAS files:
cloud_nw.las
cloud_ne.las
cloud_sw.las
cloud_se.las
