Lidar Data and Related Imagery

The files on this page are from the Oregon Lidar Consortium (OLC),
Courtesy City of Springfield, Oregon

The sample data files here can be used while learning the tools whose description begins on the main page. The LAS files in the first column of the table below have no per-point RGB. The orthorectified areal imagery in the second column covers the same area as does the corresponding file in the first column. Using LASVisEdit.jnlp or LASVisEditWW.jnlp, you can add color from an image in the second column to create a color infused LAS data file. The edited LAS files in the third column were created in this way. You should be able to reproduce those in the third column from files in the first two columns.

Note: The coordinates in these files are stored in Oregon Lambert International Feet. If you download and store any of these LAS files and wish to view them inside NASA World Wind by running LASVisEditWW.jnlp, be sure to store your local copies so that some ancestor directory has OLIF in its name.

File sizes: Each ".las" file is between 100 and 200 megabytes; each .tif file is approximately 72 megabytes.

Technical Notes on the Imagery

Each orthoimage is generally a mosaic of "sweet spots" taken from several photographs. A "sweet spot" is an area in the center of a photograph with the least distortion. For further information:
