Create Elevation Contours from LIght Detection And Ranging (Lidar)

  • Procedure

Obtain LiDAR data

  1. Source 1 - Obtain lidar data from and at Southern Nevada Water Authority
    1. SNWA Metadata
    2. LiDAR dataset is in LAS 1.1 data format
    3. collected on 1 meter posting or 1.4 meter
    4. Bare Earth class are 2, 8, 25, and 26
    5. When creating contours use classess 8, 25 (roads and dark ground surface), and 26 (overpass). Note sure why the metadata doesn't include class 2 (bare earth)
    6. Data project in UTM Zone 11 North, WGS84 on the Ellipsoid
    7. Vertical projection is on the GRS80 ellipsoid.
  2. Source 2 - download the same data from USGS - National Map - Lidar Point Cloud
    1. USGS Metadata
    2. NAVD88 vertical datum (so are the elevations ellipsoid like SNWA or based on the Geoid model?)
    3. WGS_1984_UTM_Zone_11N
    4. USGS Lidar Metadata
  3. Background on LiDAR data
    1. when creating the clipping boundary, ESRI says it must be in the same projection as the dataset, so in this case Lidar data is in UTM, then clipping boundary also needs to be in UTM. The clip didn't work when I used Stateplane coordinates, so Surface Contour took 2 hours and created contours for all of Southern Nevada (also had wrong elevations). According to Margaret J. ESRI tech support, Surface Contour command doesn't honor the clip boundary when using Lidar dataset.
    2. How do you clip a Lidar dataset? According to Margaret J. ESRI tech support, need to first convert into a multipoint feature, then clip that.
    3. Classification Value = 2 Ground, see Working with LAS classification in ArcGIS
    4. ArcMap Lidar Properties - Filter

Convert LiDAR elevations from ellipsoid to Geoid heights

  1. NOAA Vertical Datum Transformation -
    1. NOAA Vertical Datum Transformation Download VDatum (select
  2. edit E:\downloads\\vdatum\vdatum.bat
    1. edit the path on the last line to read
    2. “C:Program FilesJavajre1.8.0_65binjava.exe” -jar vdatum.jar
  3. LiDAR data is tiled by Assessor Book and Section number
    1. class_14008_prelim.las
    2. class_14009_prelim.las
    3. class_14016_prelim.las
    4. class_14017_prelim.las
  4. takes about 7 minutes for VDATUM to process one .las file
  5. contours are funky around the edges, so if project is close or straddles lidar boundary, then process both
  6. NOAA Vertical Datum


  1. unzip file
  2. load LAStools in ArcToolbox (right click on ArcToolbox and select Add Toolbox…)
    1. E:downloads\\LAStools\ArcGIS_toolboxLAStools.tbx
  3. run las2las (filter)
  4. drop z values below 550 meters
    1. if this range is narrow, then will save time editing the contours, removing building elevations, trees, cars, etc which skew the topo. Recommend doing an iteration to find the highest and lowest elevations onsite and around it. Then use this value here in las2las.
    2. drop z values above 750 meters
    3. drop_classification 0, 1, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24
    4. ArcToolbox las2las (filter)

    2. Z Coordinate System > Vertical Coordinate Systems > North America > NAVD1988 (elevation in meters)
  5. check Compute Statistics
  6. check Store Relative Paths
  7. ArcToolbox Create LAS Dataset

Surface Contour in Feet

  7. Symbology tab > remove outlyers (values less than 0 and greater than 1000)
    1. ArcMap LAS Layer Properties - Bogus Data

Project Contours to Stateplane Coordinates

  1. Need a file geodatabase to store the contours in
  2. ArcToolbox > Data Management Tools > Projections and Transformations > Project
    1. project from UTM to Stateplane coordinates
  3. Z Coordinate System tab > (NAVD88 feet)
    1. ArcToolbox Project Stateplane Coordinates

  1. Need 3D Analyst Extension enabled (Customize > Extensions > check 3D Analyst)
  2. ArcToolbox > 3D Analyst Tools > Conversion > From File > LAS to Multipoint
    1. output feature class in a file geodatabase Lidar2010MultiPnt
    2. Average Point Spacing is 1 meter
    3. Input class codes 2, 8, 25, 26
    4. Input Return Values - check Any returns
    5. Coordinate System: leave blank, should be WGS_1984_UTM_Zone_11N
    6. Z Factor is 1
    7. takes about 1.5 hrs to run
    8. ArcToolbox LAS to Multipoint
    9. ArcToolbox LAS to Multipoint
  1. ArcCatalog > right click > New > LAS Dataset > SNWALidar2010.lasd

Create IDW Surface

  1. ArcToolbox > 3D Analyst Tools > Raster Interpolation > IDW to convert Multipoint dataset into surface raster
    1. elevation Shape.Z
    2. cell size 3.28 ft
    3. ArcToolbox IDW

Generate Contours

  1. ArcToolbox > 3D Analyst Tools > Raster Surface > Contour
    1. Problem, appears elevation values are still in meters, not converted to feet (even when I set the Z coordinate in the project tab, it doesn't change the value)
    2. Input raster: IDW surface
    3. Output polyline features: file geodatabase
    4. Contour interval = 1
    5. Z Factor = 3.2808 (1 meter = 3.2808 feet)
  2. Compare values with GISMO 2003 5 foot contours values (E:gisdata\crgeo\shapefil\con5f03_l.shp)

Smooth Contours

  1. ArcToolbox > Cartography Tools > Generalization > Smooth Line
    1. smoothing tolerance 50 feet
  2. Reference
  3. Create a file geodatabase to store surface contour data

Export Contours to Shapefile

  1. con1f14017
  2. ArcToolbox > 3D Analyst Tools > Triangulated Surface > Surface Contour
    1. Use this to convert directly from LAS LiDAR to Contours. Problem is the dataset is too big, so don't recommend this step.
    2. turn off geoprocessing in the background, Geoprocessing > Geoprocessing Options > uncheck Enable Background Processing
    3. (skip - doesn't work with Lidar datasets) change the Environment > Processing Extent to a polygon boundary (e.g. G5 Medical offsite basin boundary/project limit)
    4. use Contour interval of 1 which is unitless (contours increase by 1), no need to enter units, such as 2 ft = 0.6096 meters

Adjusting GPS and Benchmarks

  • Problem - I have two different elevations, one from GPS using the Geoid and the other County published Benchmark. Using TBC, how do I adjust all the GPS data so it uses the benchmark elevations?

Trimble Business Center

AutoCAD Civil 3D

  • Remember, Civil3D can only import a points file saved in ANSI/ASCII text file, so either Excel or TBC exports the points file in another format UTF. I had to use UltraEdit to open the file, then Save As ANSI/ASCII then Civil 3D would import the points file.
  • Remember, AutoCAD doesn't understand Civil 3D points, so need to convert to blocks

Step 3 Civil 3D - add subset of street centerline boundary shapefile

    • OPTIONS > Profiles tab > CLV2014.C3D > Set Current
    • NEW
    • should have layers like VS-CL and V-ANNO-LBL
  • assign coordinate system
    • Application Menu > Drawing Utilities > Drawing Settings
    • Units and Zone tab > USA, Nevada category
      • NAD83 NCRS, Las Vegas Zone, US Foot
        • Selected coordinate system code: NV83.NCRS-LVF
      • NV83-EF coordinate system (old GIS data)
      • AutoCAD Civil 3D Drawing Settings
  • MAPIMPORT shapefiles
    • Field Heading - Drawing Layer = VS-CL
    • Field Heading - Data = Create object data, then Select Fields, uncheck everything but STRNAME field
    • AutoCAD Civil 3D Map Import
  • Zoom Extent (Z E or ZE)
  • verify street centerlines should be assigned to VS-CL layer
  • Modelspace Annotation Scale, change from 1“=1' to 1”=100'
  • make V-ANNO-LBL layer current
  • Annotate Tab > Text Style CLV-Bold.10
  • MTEXT the street name, need to have a better solution to add annotation
    • Clark County GIS - OpenWeb Application - Streets Surrounding Site
    • Civil 3D Label Street Names Surrounding the Site
  • Optionally Add Aerial Photos
    • add Bing Maps (just a rough overlay, better if we done GPS survey)
    • use MAPIINSERT to import GIS Aerial Photos
    • Layer
      • VA-GIS
      • VA-IMG
      • IMAGE

Step 4 Civil 3D Import Parcel

  • GIS Assessor Parcel Layer
    • PARCEL
    • Drawing Layer = V-PROP-BNDY-GIS
    • Data = APN (uncheck everything else)
  • check on Import polygons as closed polylines
  • MTEXT parcel number and owner name
  • Save As step04ImportParcel.dwg and close
  • optionally - save as AutoCAD 2004 and give to Clair/Josh

Step 5 Civil 3D Create Existing Surface

Step 6 Civil 3D Create Proposed Surface

  1. Determine the existing elevation of the street centerline at the center of the building footprint. Say this elevation is 1900 ft. Then the Finish Floor (FF) Elevation will be 18 inches above that, so FF = 1901.50 ft.
  2. Create a feature line of the building footprint and assign the FF elevation
  3. Determine lot drainage
    1. RFCD Typical Lot Drainage
    2. A, B, C Lot Drainage
    1. Lot Drainage

Cleanup DWG

  • PURGE - remove unused blocks
  • UCS - delete any named coordinate systems

Step 8 Revit - create building footprint

  • Create building footprint in Revit, doesn't matter where its located
  • Create driveway
  • Save (01BasicBldg.rvt) and close.
  • New Project based on Residential template, save as Step09LinkCAD.rvt
  • Project Browser > Site Plan (double click to activate)
  • Insert > Link CAD then select the site plan drawing from Civil 3D
    • Revit Link CAD
  • ZA Zoom All
  • VG Visibility Graphic > Site > check on Survey Point (will turn on Project Base Point later)
  • move Survey Point to corner of lot with pin/clip (paperclip icon) state off (red diagonal line through the paperclip)
  • Manage > Project Location panel > Coordinates > Acquire Coordinates (then select DWG parcel boundary)
  • VG Visibility Graphic ? Site ? check on Project Base Point
  • move Project Base Point to a corner of the lot (unsure if clip state should be on or off)
  • Save As SitePlan.rvt
  • select site boundary
  • Properties > Shared Site > DefaultLocation
  • Record current position as DefaultLocation > Change > Duplicate > Name = SiteCoords
  • Revit Select Site

Step 10 Revit - Publish Coordinates

  • Insert > Link Revit - to link in building footprint (.rvt) into the civil engineering site (.rvt)
  • position building using Move and Rotate
  • with building footprint still selected, Properties ? Shared Site ? Publish the current shared coordinate system…
  • Change to SiteCoords > Reconcile
  • Save
  • Revit Coordinates/Origin Point
    • Relative/Project Internal Coordinates - center/middle of the screen from the intersection of the 4 elevation symbols, can export to DWG using this coordinate, but why?
    • Project (circle with X icon)- can NOT export to DWG using this coordinate
    • Survey/Shared Coordinates (triangle with dot icon) - can export to DWG using this coordinate (this is what we want)
    • Not Shared, Publish or Acquire (use this, acquire from Civil 3D)

Step 11 Revit - Shared Coordinates

  • Link Revit - insert the building footprint onto the site plan. Move and rotate the building to fit on the site. Then Publish coordinates from Site to Building Footprint. VG turn on Project location and move on to the site. Save the file.
    • Revit Shared Coordinate

Step 12 Revit - export building footprint to Civil 3D

  • Open Building Footprint
  • Application Menu > Export > CAD Formats > DWG
  • Select Export Setup click the … button
  • Units & Coordinates tab > Foot
  • Units & Coordinates tab > Coordinate system basis = Shared
  • Revit Export to DWG using the Survey/Shared Coordinate
