Create Integrated Mesh Scene Layer Package (Data Management)


Creates a scene layer package from OpenSceneGraph binary (OSGB) data.


  • Similar to other 3D graphic formats, the OSGB data format does not natively support specifying or capturing the coordinate system of the model. Typically, OSGB format files are output in a Cartesian coordinate system that locates data at fixed coordinates. The x-, y-, and z-coordinates of the model are not inherently geographic locations; rather, they are locations relative to an arbitrary geometric origin (0, 0, 0). One typical coordinate system used for such models is the Easting-Northing-UP (ENU) convention, in which the x-axis can be thought of as an easting direction, the y-axis as a northing direction, and the z-axis is up. To properly georeference the model, an additional metadata .xml, .3mx, or world file (.wld3) is required that can be placed next to the folder that contains the OSGB format files or specified through the Anchor Point parameter.

  • If no file exists to georeference the model, a world file (.wld3) can be created to specify the origin. This space or comma delimited file can be formatted in decimal degrees as <From x,y,z> <space> <To x,y,z>.

    An example world file to georeference the model. Only one coordinate pair needs to contain the anchor point coordinates.

  • If the OSGB format files were created with a known coordinate system, place the projection file (.prj) next to the folder that includes the OSGB format files to properly georeference the model. For example, if the input file path is C:\temp\data and the OSGB format files are in subfolders C:\temp\data\Tile_001 and C:\temp\data\Tile_002, place the projection file or metadata file in the C:\temp\data folder.

  • The following table lists the georeferencing file to use for each input coordinate system of the OSGB model:

    Input coordinate systemGeoreferencing file

    Local coordinate system (ENU)

    .xml, world (.wld3), .3mx, or point feature class

    Projected coordinate system

    Projection file (.prj)

    Geographic coordinate system

    Projection file (.prj)

  • OSGB format files are created by Drone2Map and third-party providers. For a complete list of these providers, see Integrated mesh scene layer.

ParameterExplanationData Type

The OSGB format files, or folders containing OSGB format files, that will be imported into the integrated mesh scene layer package. This parameter allows a selection of multiple OSGB format files or a selection of multiple folders containing OSGB format files.

File; Folder

The integrated mesh scene layer package that will be created.


The point feature or .3mx, .xml, or world (.wld3) file that will be used to position the center of the OSGB model. If there are multiple points in the feature class, only the first one will be used to georeference the data.

Feature Layer; File

Specifies the files that will be processed for the input dataset.

  • *All binary files, regardless of their extension, will be processed to determine if they are in the OSGB format.
  • osgbOnly files with the .osgb extension will be processed.

The coordinate system of the output scene layer package. It can be any projected or custom coordinate system. Supported geographic coordinate systems include WGS 1984 and China Geodetic Coordinate System 2000. WGS 1984 and EGM96 Geoid are the default horizontal and vertical coordinate systems, respectively. The coordinate system can be specified in any of the following ways:

  • Specify the path to a .prj file.
  • Reference a dataset with the desired coordinate system.
  • Use an arcpy.SpatialReference object.

Spatial Reference

The maximum texture size in pixels for each scene layer node.
