Note: More tasks are present on the web interface.

task_pointdb	description
import	import point data from files
rasterize	create visualization raster from points
index_raster	fill a raster with point index metrics
to_pointcloud	convert pointdb layer to pointcloud layer

---

task_pointdb: “import”

Import point data from files ( .las and .laz), recursive processing: Files in sub folders of source will be included.

pointdb properties needs to be specified in config.yaml. Target path will be created. Only one layer can be stored at one path (folder).

name	value
pointdb	target: pointdb layer name (target path may not exist, if existing add points to existing layer) Note: Do not import same files multiple times, points in layer are then duplicated)
source	source directory with las/laz files as absolute path or relative to rsdb root folder path

{task_pointdb: "import", pointdb: "layer1", source: "/media/lidar_data"}

task_pointdb: “rasterize”

create visualization raster from points

name	value
pointdb	source: pointdb layer name (needs to be existing)
rasterdb	target: rasterdb layer name (delete if existing and create new)
transactions	(optional, default: true) true/false (true: processed part of data will be accessible when server is terminated in middle of operation, false: processing is faster)

{task_pointdb: "rasterize", pointdb: "layer1", rasterdb: "layer1_rasterized",  transactions: false}

task_pointdb: “index_raster”

Pixels of an existing rasterdb layer are filled with index metrics calculated from pointdb layer. rasterdb layer can be created with task_rasterdb: "create", if it does not exist.

name	value	format
pointdb	source: pointdb layer name (needs to be existing)	“pointdbID”
rasterdb	target: rasterdb layer name (needs to be existing)	“rasterdbID”
indices	list of index metrics to calculate	[“index1”, “index2”, “index3”]
rect	specifies a rectangle in target rasterdb that should be processed	[xmin, ymin, xmax, ymax]
mask_band	(optional) band number in target rasterdb. specifies which pixels should be calculated, if not specified all pixels will be calculated	bandIndex

{task_pointdb: "index_raster", pointdb: "myPointDB", "rasterdb": "myRasterDB", "indices": ["BE_H_MAX"], "rect": [608976, 5524981, 609094, 5525066]}
{task_pointdb: "index_raster", pointdb: "myPointDB", "rasterdb": "myRasterDB", "indices": ["area", "BE_H_MAX"], "rect": [608976, 5524981, 609094, 5525066]}
{task_pointdb: "index_raster", pointdb: "myPointDB", "rasterdb": "myRasterDB", "indices": ["area", "BE_H_MAX"], mask_band: 1}
{task_pointdb: "index_raster", pointdb: "myPointDB", "rasterdb": "myRasterDB", "indices": ["area", "BE_H_MAX"], mask_band: 1, "rect": [608976, 5524981, 609094, 5525066]}

task_pointdb: “to_pointcloud”

Conversion from pointdb layer to pointcloud layer

name	value
pointdb	source: pointdb layer name (needs to be existing)
pointcloud	target: pointcloud layer name (delete if existing and create new)
transactions	(optional, default: true) true/false (true: processed part of data will be accessible when server is terminated in middle of operation, false: processing is faster)

{task_pointdb: "to_pointcloud", pointdb: "area", pointcloud: "cloud", transactions: false}
