![]() ![]() A LAZ file with missing coordinate system information can define one through the Input Coordinate System parameter.For LAS and ZLAS files, a PRJ file can be generated with the Create LAS Dataset tool. If the LAS, ZLAS or LAZ files being processed have missing or incorrect spatial reference information, a PRJ file with the same name can be placed in the same location as the file to override the information in the header.If all of the LAS, ZLAS, or LAZ files being processed have unknown coordinates but use the same spatial reference, only one file will need to have a PRJ defined for the tool to process the collection. The PRJ file will override the information in the header and can be used to rectify missing or invalid spatial reference information. If multiple coordinate systems are used by the desired collection of LAS or ZLAS files, consider using the Extract LAS tool to reproject the data to a common spatial reference.Ī LAS, ZLAS, or LAZ file can have its spatial reference defined in its header or by a PRJ file with the same base name that is placed in the same location. If certain fields are not needed in the resulting scene layer, consider hiding the unwanted columns.Īll LAS, ZLAS, or LAZ files being processed must have the same spatial reference. When using a feature layer as input, only the fields designated as visible in the layer properties will be preserved in the scene layer package. The elevation of multipatch layers must be defined with absolute heights, whereas point layers can be on the ground or offset from the ground. For 3D features with undefined z-units that differ from the x,y units, consider using either the Adjust 3D Z tool to convert z-values to a matching linear unit or the Define Projection tool to define the correct z-datum. If the output scene layer package will store x,y values in projected coordinates and the z-coordinate system is not defined, the vertical units will be the same as the x,y coordinates.If the z-coordinate system is undefined, the vertical units will be in meters. If the output scene layer package will have x,y coordinates in GCS WGS 84, the z-coordinate system can be defined using any ellipsoidal datum or EGM96 or EGM2008 through the Spatial Reference parameter.Note the following considerations for how z-coordinates are defined in the 3D data being processed: If the intended display environment will be a global web scene view, the output coordinate system must use GCS WGS84. The output coordinate system should match the spatial reference of the web scene in which it will be displayed. ![]()
