Creating a Layer in LP360 for Windows
The Add Files dialog box is used to open LAS files, raster files and Feature/Shape files and add them as one or more layers to the map. See Add LAS Files Dialog Box for more information. Once a layer is added, you can view it, along with any other opened layers, in the Table of Contents (TOC). You can use the TOC list to display or turn off display of layers, organize the list of opened layers, and modify the layer's properties using the right-click menu.
Layers are integrated into the LP360 user interface. When a layer is created and added to the map, the layer is listed as another layer in the Table of Contents (TOC) view. It can be turned on or off, dragged up or down in the layers collection, and modified to have different layer properties.

How to Create a Layer
-
Click the Add Data Layer command
on the LP360 toolbar.
The Add Files dialog will open.
-
Select the files to add by doing one of the following:
-
Click the Add Files button
to select one or more files.
-
If you have one or more folders from which you want to add all files contained within them, click Add Folder
.
Note The Add Folder command allows you to add all the files of one folder or of multiple folders. You can use the Ctrl and Shift keys to select more than one folder at a time. All files in all the folders selected will be added as one layer.
-
-
Look at the file list in the Add Files dialog box. You will see the header information for each file selected. Each column represents a field in each file, so with the file list, you can see much information about the file: the file size, the date of acquisition, the layer that the file is displayed in, the coordinate system used, etc. For more information and details about fields contained in the files, see the Add LAS Files File List.
-
In the Open Setting area (only on the LAS tab), select whether you want the LAS files you selected to open with a Read-Only restriction or if you want the LAS files to be opened Read-Write access after the files are loaded into the map layer.
-
In the Load Setting area (only on the LAS tab), select either Load Files to display the points in the files or Load Footprints Only to display outlines or placeholders of the individual LAS files. In this case, the areas inside the footprints will be empty (i.e., no points will be displayed).
-
In the Options area, select any of the following options for the display of the files.
-
Click Append to Compatible Layers if you want any files selected to add that have the same required criteria as files in existing map layers to be automatically added to the open layer. Leaving this item unselected will create a new layer even if the files' criteria match an existing layer.
-
Click Ignore Incompatible CRS if you want to ignore the LAS file Coordinate System when computing compatible Map Layers.
-
Click Pyramid if you would like the files pyramided upon being added to the layer. See Pyramiding Files for more information on pyramiding LAS files or if you would like to pyramid the files at a later time.
-
(LAS files only) Enter Thinning Factor to determine the number of layers in the pyramid, if you selected Pyramid. An intermediate thinning factor of 16 is recommended.
-
-
Click OK to complete the adding files process.
Notes
- An "undefined" Project SRS will be automatically set by the Add Files dialog when only LAS, Raster or Feature layer is added . If all three types are added at the same time, the priority used to set the Project SRS is: 1. LAS 2. Raster 3. Feature.
- If you choose not to build pyramids for the files during this process, you may still do so later. To repyramid the files with another thinning factor or to later pyramid the files if you decide not to at this point, follow the instructions in Pyramiding Files.
If using more than one LAS file, the created LIDAR Layer will only display the LAS file boundaries. To see points, you must first load the LAS files.
