3 PowerDraft Connect Edition Less expensive version of MicroStation Connect Edition (half price) 64 bit software Has all the tools needed for normal project work TerraScan, TerraPhoto, TerraMatch and TerraModeler run on PowerDraft TerraScan Lite, TerraPhoto Lite and TerraModeler Lite run on PowerDraft

4 Bentley Select Annual fee based program Ensures you can always use the most up to date versions of Bentley software Portfolio balancing allows customer to swap Bentley licenses to other Bentley licenses for the same value at the change of select contract year For example: swap two MicroStation seats to four PowerDraft seats

5 Various Improvements LAS 1.4 work: Set withheld bit option in Delete by class macro action Set withheld bit option by Delete by line macro action Support for LAS 1.4 waveform data Image number and Distance field types added to user point formats Split at gaps menu command in Manage Trajectories can now use loaded points (required a project earlier) Set AccuSnap off in Settings switches AccuSnap off whenever TerraScan starts Multiply by setting added to Fix time example: convert millisecond time stamps to seconds Support for OSTN15 projection system with correction grids Support for SBTC/SBIC trajectory format as input

6 Faster Display Speed Faster display speed whenever displaying points Biggest improvement in speed when Use depth is on Makes it practical to use as the normal display mode Faster shaded surface display

7 Inside fence & Multiple polygons Inside fence setting in all tools operating on points accepts multiple selected polygons Note: not supported in TerraSlave

8 Group & Group+intensity display modes Two new display modes to work with groups Group + intensity shows grouped points with color and non-grouped points using automatic intensity grey scale coloring

9 Fit to view in elevation coloring Fits elevation dynamically scheme to view contents Helps to see elevation differences when zoomed in

10 Camera option in Synchronize Views Creates a camera view which shows the same area as source view Example use: Whenever user creates a cross section in view 3, software shows in view 7 the same feature seen thru an oblique image

11 Building Vectorization Various Improvements Remove Details has an option to specify area limit in a text field Split Building tool waits for user to enter a splitting line if no fence active Two logic improvements better quality as a result

12 Mouse Point Adjustment as Keyin Keyin parameters for Mouse Point Adjustment Makes it feasible to link different adjustment modes to function keys Example: Mouse Point Adjustment AdjZ=1/AdjXy=0/Point=Closest/Class=2/Within=0.5

13 Reference Points and Fitting to Reference Read reference points menu command reads points to use as reference Fit to reference menu command fits a point cloud to match reference points Example use at a mining site: Read most recent photogrammetric point cloud as active points Read older photogrammetric point cloud as reference points Classified locations where real change has taken place Fit active point cloud to match reference using locations which have not changed This gives two matching point clouds can compute volumes between two

14 Thinning Points to Fixed Density Grid 2d and Grid 3d methods added to Thin points Grid 2d makes it possible thin data inside selected polygons to a fixed density Example use: military requires that published data can not exceed 1 point / m²

15 Draw polygons as macro action Draw polygons can run as macro action Macro creates one text file for each block Use Tools / Read / Polygons menu command to draw text files into design Can create polygons for groups as well

16 New Options in Classify by Range Offset distance classifies based on how far left or right a point is from scanner Forward distance classifies based on how far forward or backward a point is from scanner Example: classify points which have seen the front sides of traffic signs

17 Compute distance Compute distance menu command computes a distance value and stores it as an attribute for points Distance value can be: Elements (distance from design file elements) Closest line 3D (3d distance to closest overlapping line) Closest line dz (dz to closest overlapping line) Line average Z (dz to average elevation of overlapping lines) Ground class (typically height above ground) TIN model Following tools use height above ground distance value: Classify / By distance Assign groups Classify groups / By best match

18 Classify / Surface points Classifies points matching a local smooth 3D surface Needed in processing noisy data Resulting class contains points which give less noisy surfaces

19 Smoothen / Xyz New option in Smoothen points Modifies xyz of points so they would match a local surface better in 3D Optional step when processing noisy data

20 Tree Database Population Tools New set of tools for populating a tree database Each tree is given following possible attributes: Tree species Center point with ground elevation Height Canopy width Trunk width Pass this information for city or powerline tree maintenance database Source data can be: Airborne LiDAR and Street View images Airborne LiDAR and oblique airborne images Airborne LiDAR and mobile images Future: mobile LiDAR Future: mobile LiDAR and images

21 Create Tree Cells Creates tree cells for groups inside fence User assigns a tree species for each tree point class Software computes tree center point, ground elevation, height and canopy width from point cloud Use Modify Tree Cells to check each tree cell

22 Place Tree Cell Place one tree manually Section view: trunk ground elevation comes from mouse click All other views: trunk ground elevation from ground class points

23 Modify Tree Cells For checking the information of each tree one at a time Organized list to go thru and check Automates view setup Select tree cells before starting the tool Check, modify if needed and approve trees one at a time

24 Output Tree Cells Writes a tab delimited text file with tree information Text file is suitable for importing into a database Select tree cells before starting this tool Tilia vulgaris Tilia vulgaris Tilia vulgaris Betula pendula Picea abies Picea abies Tilia vulgaris Tilia vulgaris

25 Tools / Read / Tree cells Menu command for reading trees from text file(s) produced with Output Tree Cells

26 Show Street View Opens Google Street View image in browser User enters two mouse clicks: 1. Desired camera location 2. Target point Google gives closest available camera image looking at given heading direction
