What It Does

Screenshot graphic of LIDAR Data Handler 8 menu options

The LIDAR Data Handler for ArcMap 8.x contains many of the same options as the ArcView 3.x version; however, some functionality was changed or removed to be compatible with ArcMap 8.x. The available options are designed to help manipulate and display grids. Although it was designed with digital elevation models (DEMs) and LIDAR data in mind, many of the tools could also be used with other kinds of grid data.

Activating the LIDAR Data Handler in ArcMap

  1. Unzip the downloaded file to a temporary location
  2. Run the set-up program to install and register the extension and new functionality to ArcMap
  3. Start ArcMap
  4. From the Tools menu, select Extensions. In the Extensions window, activate the checkbox for the LIDAR Data Handler entry
  5. Close the Extensions window
  6. From the View menu, select the LIDAR Data Handler toolbar

A new toolbar entitled LIDAR Data Handler will be available for the ArcMap project.

Options

  • Data Loader allows you to rename and load data files downloaded using the LIDAR Data Retrieval Tool (LDART) into a map document within ArcMap.

There are two options for working with the legend:

  • Apply LYR File Symbology applies the symbology stored within a layer file to data layers within the active data frame that are the same type.
  • Apply Symbology applies the symbology from a selected layer file within the active data frame to other data layers within the data frame that are the same type.

Grid Profiler creates profiles or transects across selected grid themes.

There are three options that allow you to manipulate and extract grid data:

  • Grid Subtractor subtracts one grid from another.
  • Cut/Fill Calculator is disabled for ArcMap 8.x because of invalid results returned from the "cut/fill" command in ArcGIS. It calculates volume and area gained and lost from a difference grid (such as one calculated by Grid Subtractor).
  • Grid Clipper clips a grid by a selected polygon theme or graphic. This can be useful if you want to calculate differences for a small section of your grid.

Graphic to Shape converts a selected graphic (perhaps one that you have used to clip a grid) to a polyline or polygon theme.
