[GIS program] lastools DL : 0: 该程序包包含如下转换程序，可以完成激光雷达数据的多种格式的转换。 txt2las.exe las2txt.exe lasinfo.exe las2shp.exe shp2las.exe las2tin.exe las2dem.exe las2iso.exe lasboundary.exe lasmerge.exe las2las.exe lasthin.exe lasview.exe laszip.exe-The program txt2las.exe converts LIDAR data from standard ASCII in various formattings to binary LAS format (version 1.2). The corresponding las2txt.exe turns binary LAS into human-readable and easy-to-parse textual representations. The tool lasinfo.exe prints out a quick overview of the contents of a LAS file, las2shp.exe turns binary LAS into ESRI s Shapefile format, shp2las.exe turns an ESRI s Shapefile into binary LAS, lasmerge.exe can merge several LAS files into one, las2las.exe allows extracting only last returns, only points within a bounding box, etc., lasthin.exe implements a simple point thinning algorithm, las2tin.exe triangulates the points of a LAS file into a TIN, las2dem.exe rasterizes them into a DEM, las2iso.exe extracts, optionally simplified, elevation contours, and lasboundary.exe computes a boundary polygon (i.e. a concave hull of the points). The little OpenGL viewer lasview.exe visualizes the contents of a LAS file and can also compute a TIN. It needs the GLUT32
