The 2013 LiDAR data was used for the City’s coastal flood model, which was done as part of the City’s climate adaptation strategy. Data access Each of the 168 polygons on the map or rows in the table provides two links to the data. One is in GeoTIFF format (zipped, file sizes range from 12 KB to 15.8 MB), the other in LAS format (zipped, file sizes range from 1.0 MB to 349.8 MB).

Attributes Point data was classified as: Bare-earth; Low vegetation; High vegetation; Water; and Buildings Data currency Data was collected on February 7, 15, and 19, 2013 and is current as of those dates.
