The LiDAR data files do not have the same extent as the vector files, and they should. I think I incorrectly imported them.
There are two flavors of the files: ESRI Grid and Shapefiles. I used the Grid files, specifying hdr.adf as the file to use. But, since the .prj file is specified when importing a shapefile I wonder if that's what I need with the Grid format. The metadata.xml has these bounds: <westbc Sync="TRUE">-123.253402</westbc> <eastbcSync="TRUE">-123.131197</eastbc> <northbcSync="TRUE">45.002688</northbc> <southbcSync="TRUE">44.925436</southbc> and <leftbc Sync="TRUE">600316.500000</leftbc> <rightbcSync="TRUE">631069.500000</rightbc> <bottombcSync="TRUE">1169386.500000</bottombc> <topbc Sync="TRUE">1196554.500000</topbc> Looks like both long/lat and Oregon State Plane coordinates are provided. The prj.adf file contains: Projection LAMBERT Datum HPGN Spheroid GRS80 Units 3.280839895013123 Zunits NO Xshift 0.0 Yshift 0.0 Parameters 43 0 0.0 /* 1st standard parallel 45 30 0.0 /* 2nd standard parallel -120 30 0.0 /* central meridian 41 45 0.0 /* latitude of projection's origin 400000.0 /* false easting (meters) 0.0 /* false northing (meters) The Shapefile for the area including my project has this projection: PROJCS["Lambert Conformal Conic", GEOGCS["GCS North American 1983 HARN",DATUM["D North American 1983 HARN",SPHEROID["GRS 1980",6378137.0,298.257222101]], PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]], PROJECTION["Lambert Conformal Conic"], PARAMETER["False Easting",1312335.958005249], PARAMETER["False Northing",0.0], PARAMETER["Central Meridian",-120.5], PARAMETER["Standard Parallel 1",43.0], PARAMETER["Standard Parallel 2",45.5], PARAMETER["Latitude Of Origin",41.75], UNIT["Foot",0.3048]] Should I put these source files in the WGS84-lat-long location, the Oregon-ll83 location, or the project location which is the Oregon State Plane projection? And, do I import the Grid or shapefile? I'm confused.
