readers.slpk¶
Scene Layer Packages (SLPK) is a specification created by Esri as a format for their 3D Scene Layer and scene services. SLPK is a format that allows you to package all the necessary I3S files together and store them locally rather than find information through REST.
Example¶
This example will unarchive the slpk file, store it in a temp directory, and traverse it. The data will be output to a las file. This is done through PDAL’s command line interface or through the pipeline.
- ``pdal traslate PDAL/test/data/i3s/SMALL_AUTZEN_LAS_All.slpk
- autzen.las –readers.slpk.bounds=”([-123.075542,-123.06196],[44.049719,44.06278])”``
Options¶
- filename
- SLPK file must have a file extension of .slpk.
Example:
pdal translate /PDAL/test/data/i3s/SMALL_AUTZEN_LAS_ALL.slpk output.las
- bounds
- The bounds refers to the extents of the resource in X, Y, Z coordinates with the Z dimension being optional. This must be input as a string.
Example:
readers.slpk.bounds="([xmin,xmax],[ymin,ymax],[zmin,zmax])"
- dimensions
- These are the dimensions that the user would like to use for this read of the SLPK archive. Only these dimensions will be added to the layout. Here is a list of supported dimensions and their corresponding PDAL dimensions:
- Esri Pdal =============== =============== INTENSITY Intensity CLASS_CODE ClassFlags FLAGS Flag RETURNS NumberOfReturns USER_DATA UserData POINT_SRC_ID PointSourceId GPS_TIME GpsTime SCAN_ANGLE ScanAngleRank RGB Red
Example:
--readers.slpk.dimensions="rgb, intensity"
- min_density and max_density
- This is the range of density of the points in the nodes that will be selected during the read. The density of a node is calculated by the vertex count divided by the effective area of the node. Nodes do not have a uniform density acrossdepths in the tree, so some sections may be more or less dense than others. Default values for these parameters will select all leaf nodes (the highest resolution).
Example:
--readers.slpk.min_density=2
Example:--readers.slpk.max_density=2.5
