Hi,
Here is an overview of the updates relevant to Lidar data:
PointFileInformation GP tool: enhanced with option to output info on LAS files summarized (i.e., point count, spacing, z-range) by class code. Helps answer questions like - how many points in each LAS file are bare earth, what's their z-range, etc.
PointToRaster GP tool: enhanced to support LAS lidar attributes stored in BLOB fields in multipoint feature classes. Facilitates, for example, making intensity images.
All GP tools that supported TINs, with the one exception of ExtrudeBetween, now support terrains or have a replacement that supports terrains.
All terrain/TIN based tools offering interpolation (e.g. InterpolateShape) enhanced with new conflation options. Can be used, for example, to estimate shoreline height (e.g., lakes, rivers) from lidar.
Append/Delete/ReplaceTerrainPoint GP tools support both embedded and referenced feature classes. Referenced feature classes properly update LAS BLOB attributes if present. These tools can also operate on polygon based areas of interest, not just rectangles.
Terrain dataset has new �??anchor point�?? option for critical points such as control points, navigation hazards, etc., that are guaranteed to remain present throughout all pyramid levels; they never get thinned/filtered away.
New TerrainToPoints GP tool enables you to produce thinned (multi)point datasets from full res datasets using terrain�??s z-tol or windowsize filtering algorithms.
New LocateOutliers GP tool to find points outside a user specified ceiling/floor height or that are significantly different than their immediate neighbors. Confirmed data blunders/errors can be passed into DeleteTerrainPoints to have them removed from the surface.
Terrain layer has new contour renderer.
Terrain layer has new point renderers for embedded points with LAS lidar attributes. Can now symbolize points based on class code, return, intensity, etc.
New point profile tool can place points within proximity to a query line into a profile graph. Profiled points can come from either multipoint feature classes or feature classes embedded in terrains. The points can also be colored by LAS lidar attribute, e.g., class code.
Terrain overviews have been optimized to allow large terrains to be opened and viewed more quickly.
