# LIDar Tools

### las2SM
Project LAS/LAZ LIDar data to [Spherical Mercator (epsg:3857)](http://epsg.io/3857)

Example:
	
	python las2SM.py data.las SMdata.las

### las2tile

Crop a tile from LAS LIDar data and project to [Spherical Mercator (epsg:3857)](http://epsg.io/3857)

Example:

	python las2tile.py data.las 19298 24633 16


### las2ply

Export .las/.las into .ply files

Example:

	python las2ply.py 19298-24633-16.las 19298-24633-16.ply


### getPointsForID

Get the 3D points inside a OSM polygon through PostGIS using the [OSM ID](http://www.openstreetmap.org/way/264768896). For these you previously need to [load your LIDar and OSM data to your PostGIS server](recipes/postgisOSM-LAS.md)

Usage: 

```
	python getPointsForID.py <osm_id_number> <outfile>.xyz [-c / --center] [-g / --ground <meters>]
```

Example:

	python getPointsForID.py 264768896 outfile.xyz --center

## Dependences
