How are filters used in spatialfilter-safe software?
Filters point, line, area, and text features based on spatial relationships. Each input Candidate feature is compared against all Filter features, based on the given spatial tests to meet. Features that pass any or all tests are output through the Passed port; all other features are output through the Failed port. Categories Data Quality
How are the address points tested in spatialfilter?
The address points – the dataset to be tested – are connected to the Candidate input port. The building footprints are connected to the Filter port, and provide the geometry that the address points will be tested against. In the SpatialFilter parameters dialog, we make the following selections: Filter Type: Multiple Filters.
How are the filters in FME based on spatial relationships?
Filters point, line, area, and text features based on spatial relationships. Each input Candidate feature is compared against all Filter features, based on the given spatial tests to meet. Features that pass any or all tests are output through the Passed port; all other features are output through the Failed port.
Are there spatial predicates to test filter contains candidate?
Spatial Predicates to Test: Filter Contains Candidate. We want to check if each Candidate (address point) falls within a filter (building polygon). These are the key parameters – the others are left as default for this example.
How is spatial filtering used in Photon Engineering?
Spatial filtering is a technique used to improve laser quality by removing higher-order modes and noise in the beam. To accurately model laser propagation through a spatial filter in FRED, it is important to re-synthesize the light field just after the filter.
How is the diameter of a spatial filter calculated?
A spatial filter is placed at the focal point. Spatial filter diameter (14 µm) is calculated based on lens focal length and beam diameter: The spatial filter pinhole is created by adding FRED’s Custom Element object type and is described by a Circular Arc curve with radius of 0.007 mm.
