LP360 2017.1 Release Notes

 

New Features

The new and improved contour smoothing algorithm removes noisy data which causes contour jaggedness by interpolating the Z elevation around contour levels, thereby smoothing the surface and creating much better contours. This display works for both the Map View and 3D view when the user has turned on this setting via the usual Smooth Contours button  on the LP360 Toolbar or Contour Settings in the Export Wizard.

Non-smoothed Contours:

Smooth Contours with less jagged areas as a result of the new smoothing algorithm:

Users can now suppress point breakline features (ex. mass point, point constraints) when in smooth contour mode. It is located in the Contour Smoothing section of the Contour Properties page of the Layer Properties and Export Wizard dialogs. This feature can be particularly useful when there is very little point data left in an area after cleaning out unwanted points (such as heavily vegetated areas). Contours can become broken due to "rogue" breakline points in the contour smoothing band pulling tin triangles in its direction. That is, any Breakline (constraint) point with a Z within the contour smoothing band (smoothing distance) is "smoothed" out.

Example of broken contours due to sparse TIN data (breakline points in cyan):

After smoothing the breakline points out of the contour smoothing bands (points still shown):

 

Users can now add LAS/Raster/Feature data via one simple button on the LP360 Toolbar.

 

There have been some changes to the 3D Display Properties -> 3D View tab to improve performance to 3D zooming. The two zooming methods are:

1. Allowing the user to set the Zoom Rate to a value between 0.05 and 0.25. This is the traditional LP360 fixed rate zoom. However, the user is now able to change the rate of the zoom which controls the distance the eye point moves per zoom update. The zoom will always move with the same fixed percentage value (5% to 25%) offset the Z axis.

2. Automatic Rate Adjustment. This allows the rate to change more fluidly based on the user's mouse movement data. Small mouse movement means a small zoom rate, and vice versa. It is toggled on and off with a checkbox and does not use the Zoom Slider setting above.

There is a Schema Editor shortcut button included on the Feature Edit Toolbar.

 

This new Point Cloud Task supports LAS Shift/Reproject operations to a new output file. It supports reproject as well as all of the various options which can be seen in the dialog. These include converting the SRS to one defined by clicking '...' and a Shift/Scale option which allows the user to apply X, Y, Z shifting or scaling to a LAS layer. A new LAS layer with the newly shifted or scaled points will then be added to the TOC upon completion.

Here, a user may now conveniently launch Attribute Editor to edit attributes, as well as feature vertices, from the LP360 Feature Edit Toolbar using this new shortcut.

 

Users can now find the file location of feature files via a new 'Files' tab on the Feature Layer Properties dialog.

 

Users now have the option to 'Export by File' in the Export Wizard. It is found on the Export Extent drop-down menu on page two of the Export Wizard dialog. Due to the new USGS requirements for converting point data to LAS 1.4, this is a very useful and important new feature when exporting point products by file.

 

 

As LP360 no longer supports Windows XP, Windows styles have been moved to support Windows Vista and above. This improves GUI appearance and clarity and could lead to performance improvements as well. The new GUI buttons and styles are sharper and less flat than the old style.

      

      

 

Now, high-end graphics cards are able to be automatically selected by LP360 for use on nVidia® and AMD® notebooks with both integrated and discrete graphics cards. The default system setting is usually for this graphics auto-select feature to be enabled, however, if the user has set the application to specifically use an integrated graphics card, then the auto-select capability is not used and the card selection made by the user is honored.

 

In project settings, the user can set the Map SRS to be the SRS defined in the Project Spatial Reference System box, or use the SRS of the active LAS layer. This allows the map or WMS backdrop to reproject based on the option chosen.

 

The user now has the ability to still see file footprints and highlighted selections while zooming and panning about the Map View. Before, the footprints and selections disappeared, only to reappear upon finishing zooming and panning actions.

 

Users select point marker types in the Symbol and Labels Property Pages for feature data. To this point, only the default symbol was rendered in proper 3D. Now, special shapes are drawn in proper 3D as well, and they do not "float" above the surface as the user rotates the 3D window. Instead, the symbols stay connected to the surface model in their proper place.

 

Certain point cloud task dialogs (ones that take geometries and LAS layers as input) now allow the user to explicitly define the input geometries (polygon or shapefile) and LAS layers that will be used to execute the tasks.

 

A new Point Cloud Task called Grid Generator has been added, allowing the user to impose a cell grid over an input geometry and/or LAS layer based on input parameters and output the result to a shapefile.

An exciting and powerful aspect of the new Feature Edit toolbar is Feature Analyst. The Feature Analyst Dialog button allows users to view/edit the attributes of features, parts and tabs on the current layer. Feature Analyst links feature analysis directly to editing features, so that any errors found in the user's data may be immediately corrected with the editing tools. The user simply double-clicks the appropriate feature's cell he wishes to change on the Features, Parts, or Vertices tabs. The user can sort on a particular column by clicking it. If a user selects a row (or rows) on a particular tab, then that row's corresponding features, parts, or vertices (whichever may apply) will be auto-selected in the other tabs and also in the Map View. So, there is total synchronization between the Map View and each of the tabs on the Feature Analyst Dialog. Feature Analyst also synchronizes based on Auto-Z and shift geometry right-click commands accordingly. The user can also create, save, and load analysis tests in Feature Analyst Options and see the Pass/Fail results of those tests in the Feature Analyst main dialog via added columns to each for each type of test.

New support has been added for WMS/WMTS services (e.g. Image backdrops) in LP360. There are several pre-populated in the 'Add WMS Layer'  Dialog, including the Reckon WMS server. These backdrop layers are reprojected on the fly to the appropriate Spatial Reference System (SRS) as the active LAS layer is switched to a layer containing a different SRS.

 

Note: All classifications are still in the active LIDAR layer only and the Profile view is always at 100% resolution, so it has not changed.
