Developing a Topobathy Digital Elevation Model (DEM)

On April 18, 2016, Posted by , In Lidar,NPS Workflow, By , , With Comments Off on Developing a Topobathy Digital Elevation Model (DEM)

LiDAR, or Light Detection and Ranging, is a method used to remotely study the surface of the earth. LiDAR data is most commonly collected through the utilization of airplanes and helicopters; these carry the instrumentation necessary to collect these data. This specialized instrumentation consists of a laser, a scanner and…

Using LAS Datasets to Create Functional Outputs

On September 10, 2015, Posted by , In Lidar,NPS Workflow, With Comments Off on Using LAS Datasets to Create Functional Outputs

Now that we know where to download elevation data (see blog post titled “Obtaining Elevation Data from NOAA Digital Coast”), we can use these data for creating useful outputs and beautiful visual aids. This blog post will discuss how to easily create a LAS dataset, and then how to produce…

Mosaic Datasets and LiDAR Data: Advanced Processing

On September 10, 2015, Posted by , In Lidar,NPS Workflow, With Comments Off on Mosaic Datasets and LiDAR Data: Advanced Processing

This blog post builds on the techniques discussed in the “Mosaic Datasets and LiDAR Data: An Introduction” blog post. Here we go more in-depth and further explore the functionality that mosaic datasets offer LiDAR data. First, we will create a “Surface with Features” mosaic dataset, then we will create a…

VDatum to Convert LAS Data into MHW Vertical Datum

On January 20, 2015, Posted by , In Lidar,NPS Workflow, With Comments Off on VDatum to Convert LAS Data into MHW Vertical Datum

Written by: Anthony Campbell (Graduate Student) The need to convert the vertical datum of data is a problem particularly prevalent in coastal applications. For example bathymetric data is often in one vertical datum and terrestrial elevations in another. You open the data in ArcGIS hoping on the fly projection takes…
