Abstract

Jemez River Basin, NM: Post-fire landscape response NCALM Project. Jon Pelletier, University of Arizona. The survey area is defined by an 206 square kilometer irregular polygon located 12 kilometers west of Los Alamos, NM. Data were collected from May 25-28, 2012 to quantify extreme post-fire landscape response in the Jemez River basin, New Mexico.There area additional datasets covering the portions of the Catalina-Jemez Critical Zone Observatory (CZO) on OpenTopography including the Jemez River Basin Snow-on LiDAR Survey and Jemez River Basin Snow-off LiDAR Survey.

COMMENTS

Comments

High-resolution LiDAR survey covers the area of 206 km2 in the north-east part of the Jemez River basin which was burned in the 2011 Las Conchas fire. The dataset contains point cloud tiles in LAS format with the average point density of 15.24 pts/m2 and 1-m Digital Elevation Model (DEM) derived from ground-class points. This dataset, together with 2010 LiDAR datasets, are being used to quantify extreme post-fire landscape changes.

DEM was made using the same smoothness parameters (in terrascan) as the 2010 DEM data sets. this 2012 data is important for anyone who wants to difference the 2010 and 2012 bare-earth DEMs. The differences between 2010 and 2012 surveys is in the horizontal and vertical datums. The 2012 survey was referenced to the current iteration of NAD83 which is NAD_83(2011)(EPOCH:2010.0000) and the 2010 survey was referenced to the then-current iteration of NAD83 which was NAD_83(CORS96)(EPOCH:2002.0000). The error between these two datum realizations is less than 1 cm. The vertical datum for 2010 data was based on GEOID 03 and for 2012 data was GEOID 09. The error for these GEOID models is less than 6 cm. Both horizontal and datum errors are smaller than estimated survey horizontal and elevation accuracies (1 sigma).
