writers.oci

The OCI writer is used to write data to Oracle point cloud databases.

Example

{
  "pipeline":[
    {
      "type":"readers.las",
      "filename":"inputfile.las"
    },
    {
      "type":"writers.oci",
      "connection":"[email protected]/orcl",
      "block_table_name":"QFIT_BLOCKS",
      "base_table_name":"QFIT_CLOUD",
      "cloud_column_name":"CLOUD",
      "srid":"4269",
      "capacity":"5000"
    }
  ]
}

Options

connection
Oracle connection string to connect to database
is3d
Should we use 3D objects (include the z dimension) for SDO_PC PC_EXTENT, BLK_EXTENT, and indexing [Default: false]
solid
Define the point cloud’s PC_EXTENT geometry gtype as (1,1007,3) instead of the normal (1,1003,3), and use gtype 3008/2008 vs 3003/2003 for BLK_EXTENT geometry values. [Default: false]
overwrite
Wipe the block table and recreate it before loading data [Default: false]
verbose
Wipe the block table and recreate it before loading data [Default: false]
srid
The Oracle numerical SRID value to use for PC_EXTENT, BLK_EXTENT, and indexing [Default: 0]
capacity
The block capacity or maximum number of points a block can contain [Default: 0]
stream_output_precision
The number of digits past the decimal place for outputting floats/doubles to streams. This is used for creating the SDO_PC object and adding the index entry to the USER_SDO_GEOM_METADATA for the block table [Default: 8]
cloud_id
The point cloud id that links the point cloud object to the entries in the block table. [Default: -1]
block_table_name
The table in which block data for the created SDO_PC will be placed [Default: output]
block_table_partition_column
The column name for which ‘block_table_partition_value’ will be placed in the ‘block_table_name’
block_table_partition_value
Integer value to use to assing partition IDs in the block table. Used in conjunction with ‘block_table_partition_column’ [Default: 0]
base_table_name
The name of the table which will contain the SDO_PC object [Default: hobu]
cloud_column_name
The column name in ‘base_table_name’ that will hold the SDO_PC object [Default: CLOUD]
base_table_aux_columns
Quoted, comma-separated list of columns to add to the SQL that gets executed as part of the point cloud insertion into the ‘base_table_name’ table
base_table_aux_values
Quoted, comma-separated values that correspond to ‘base_table_aux_columns’, entries that will get inserted as part of the creation of the SDO_PC entry in the ‘base_table_name’ table
base_table_boundary_column
The SDO_GEOMETRY column in ‘base_table_name’ in which to insert the WKT in ‘base_table_boundary_wkt’ representing a boundary for the SDO_PC object. Note this is not the same as the ‘base_table_bounds’, which is just a bounding box that is placed on the SDO_PC object itself.
base_table_boundary_wkt
WKT, in the form of a string or a file location, to insert into the SDO_GEOMTRY column defined by ‘base_table_boundary_column’
pre_block_sql
SQL, in the form of a string or file location, that is executed after the SDO_PC object has been created but before the block data in ‘block_table_name’ are inserted into the database
pre_sql
SQL, in the form of a string or file location, that is executed before the SDO_PC object is created.
post_block_sql
SQL, in the form of a string or file location, that is executed after the block data in ‘block_table_name’ have been inserted
base_table_bounds
A bounding box, given in the Oracle SRID specified in ‘srid’ to set on the PC_EXTENT object of the SDO_PC. If none is specified, the cumulated bounds of all of the block data are used.
pc_id
Point Cloud id [Default: -1]
pack_ignored_fields
Pack ignored dimensions out of the data buffer that is written [Default: true]
do_trace
turn on server-side binds/waits tracing – needs ALTER SESSION privs [Default: false]
stream_chunks
Stream block data chunk-wise by the DB’s chunk size rather than as an entire blob” [Default: false]
blob_chunk_count
When streaming, the number of chunks per write to use [Default: 16]
scale_x, scale_y, scale_z / offset_x, offset_y, offset_z
If ANY of these options are specified the X, Y and Z dimensions are adjusted by subtracting the offset and then dividing the values by the specified scaling factor before being written as 32-bit integers (as opposed to double precision values). If any of these options is specified, unspecified scale_<x,y,x> options are given the value of 1.0 and unspecified offset_<x,y,z> are given the value of 0.0.
output_dims
If specified, limits the dimensions written for each point. Dimensions are listed by name and separated by commas.
tolerance
Oracle geometry tolerance. X, Y, and Z dimensions are all currently specified as a single value [Default: 0.05]
