How does the intersector function in FME work?
Computes intersections between all input features, breaking lines and polygons wherever an intersection occurs and creating nodes at those locations. Overlapping segments are reduced to one segment before being output. Evaluates one or more tests on a feature, and routes the feature accor…
How does area on area overlay work in FME?
Performs an area-on-area overlay (intersection of polygons) so that all input areas are intersected against each other and resultant area features are created and output. The resultant areas have all the attributes of the original and any overlapping polygons. View Documentation Try it Free in FME Desktop.
How are the transformer parameters set in FME?
FME Transformer Reference Guide5 Because we want to determine which parks allow dogs, we add two transformers: a Tester transformer (to filter data) and an Inspector transformer (to view results). The Tester parameters are set to filter only parks that allow dogs, and the Inspector transformer opens the Data Inspector to show the results on a map.
How does the reprojectanglecalculator work in FME?
FME Transformer Reference Guide 47 ReprojectAngleCalculator Converts a given angle from one coordinate system to another. The transformer calculates the reprojected angle of a line starting at the first coordinate in the feature, with the given length and angle.
How to set number of neighbors to Findis in FME?
In the Parameters dialog, Number of Neighbors to Findis set to 1, as we want only the single closest match to be used. Treat Polygons Asis set to Areas. Note that the default setting for Accumulation Mode- Merge Candidate – will copy the Candidate’s attributes onto the Base feature (which is what we want).
How to calculate the density of neighbors in FME?
Adding a point closest to a candidate (such as adding a point on a railway track at the closest point to a station) Finding the closest feature in a certain direction (by filtering the resulting candidate angle) Calculating clusters or density by counting neighbors within a set distance
How does candidate only mode work in FME?
Finds the nearest Candidate feature(s) to each Base feature and merges their attributes onto the Base feature. May also be used in Candidates Only mode, where each feature is considered the Base in turn and compared to all other features, but not itself. Jump to Configuration
