What It Does

The LIDAR Data Handler contains a collection of options designed to help manipulate and display grids. Once the extension is loaded into a project and a view document is active, a new menu, LIDAR Data Handler, will appear on the menu bar. 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.

Options

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

There are five options for working with the legend:

• Legend Scaler scales a legend (AVL file) to your range of data or any other range that you select.
• Legend Scaler Plus manipulates the scaling of an active legend based on a selected color ramp and specified scaling options.
  
• Add Color Ramp adds the color ramp associated with an active legend to an existing or new color ramp file.
• Legend Loader applies a legend (AVL file) to any number of selected grids at once.
• ColorMap Editor edits the red, green, and blue (RGB) values of any of the classes in the grid legend.
• Grid Profiler creates profiles or transects across selected grid themes.

There are three options for manipulating and extracting grid data:

• Grid Subtractor subtracts one grid from another.
• Cut/Fill Calculator 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.
