Regular Grid

Overview

➡️ Computes a regular grid of receivers. The receivers are spaced at a distance “delta” (Offset) in the Cartesian plane in meters. The grid will be based on:

  • the BUILDINGS table extent (option by default)

  • OR a single Geometry “fence” (see “Extent filter” parameter).

✅ The output table is called RECEIVERS

Regular grid output

Arguments

Mandatory inputs

fenceTableName — Table bounding box name

Using the bounding box of the given table name, define the envelope of the output grid:

  • Extract the bounding box of the specified table,

  • then create only receivers on the table bounding box.

The given table must contain:

  • THE_GEOM : any geometry type with the appropriate SRID

Type: String

Optional inputs

buildingTableName — Buildings table name

Name of the Buildings table. Receivers inside buildings will be removed.The table must contain:

  • THE_GEOM : the 2D geometry of the building (POLYGON or MULTIPOLYGON)

Type: String

delta — Offset

Offset in the Cartesian plane (in meters)

Type: Double

Default: 10

fence — Extent filter

Create receivers only in the provided polygon (fence)

Type: Geometry

height — Height

Height of receivers (in meter) (FLOAT)

Type: Double

Default: 4

outputTriangleTable — Output triangle table

Output a triangle table in order to be used to generate iso contours with Create_Isosurface

Type: Boolean

receiverstablename — Name of receivers table

Name of the output table. Do not write the name of a table that contains a space

Type: String

Default: RECEIVERS

sourcesTableName — Sources table name

Keep only receivers at least at 1 meters of provided sources geometries The given table must contain:

  • THE_GEOM : any geometry type.

Type: String

Output

result — Created table

Name of the table containing the results of the computation. Can be used as input for another process.

Type: String
