Fme split polygon by line Note that it creates chopped polygons I have a question about the correct combination of FME transformers, NeighborFinder, PointOnLineOverlayer and ListExploder: I LineOnLineOverlayer Overlays lines on lines, intersecting geometry, sharing attributes, and producing intersection points. (3) Drape the split polygons by the original surfaces with the SurfaceDraper. I (2) Split the polygons by the cutting line (use Intersector and AreaBuilder etc. How to convert polygons to lines and vice versa? I couldn’t figure out how the conversions are implemented in the FME. Here your files will be named BY17_1401_split_1. Now I want a polygon having area 30 units to be split from this. I'm rather surprised to find out that there don't seem to be any tools that do this, or I have created a script in FME that processes some point data. Jump to Configuration I'm creating polygons from CAD geometries with inconsistent connections. A LineBuilder will output Point, Line & Polygon depending on the coordinates supplied So simply split the string by a space to get coordinate pairs, use a vertex creator to create points and When you read from a source dataset that permits multiple geometry types in a feature class, but write to a destination dataset that is restricted to a single geometry type per class, FME 5 I'm working on creating a map where I'm trying to create a line between one point and all other points using FME. So the polylines make up a layer identifying GeometryExtractor Extracts the geometry of a feature according to the setting of the geometry encoding parameter. I want to create vertex at line where point lies. ). I found a rich set of . Jump to Configuration Typical Uses Splitting lines where they AreaBuilder Creates polygons from topologically correct linear features. But none of these could do it. The flat 3d polygons can be easily extruded with the extrude transformer. I would like to split Hi I am trying to build a connectivity model for electrical cables. When the distance between 2 points is small, the buffers overlap. All of them are 100% overlapping in plan, but some are I am trying to edit the workbench from https://fme. So I thought this would be easy to do in FME but I've had to revert to ArcToolbox to perform one step prior to running my workbench. Jump to Configuration Typical Uses Shortening or segmenting linear features How does it work? The Snipper receives features LineCloser Converts a linear feature to an area by connecting the end point to the start point. intersected lines will have attributes from polygon. An AreaOnAreaOverlayer I have a line layer and point layer snapped over line. The resulting encoded geometry is added to the feature in an attribute. Due Hello, here is my problem : I create a buffer from input points data. use the FME transformer intersector. In this post, I describe how we can use built-in QGIS processing tools to create a workflow to split polygons into equal parts. The points represent the center of a building on a campus, and DonutBuilder Cuts holes in area features where they fully enclose another area, creating donut polygons. Jump to Configuration Typical Uses Creating donut polygons How does it work? It loads your shapefile. That is if there are 25 cities in a particular county then I will have Could those objects actually be polygon slivers rather than lines? What do you see when you inspect the geometries in the FME I don't want to alter the geometry, just change the geometry type from Polygon to Multipolygon, in order to comply with a constraint. Jump to Configuration Typical Uses Splitting lines Hi, Im trying to split a large dataset of lines (~1. Jump to Configuration Typical Uses Creating areas from @najedjamal where you able to find a workaround for this? I am trying to do something similar, splitting polygon by line segment while keeping the polygon geometry intact. Background: I am working with a Feature Class which consists of digitized polygons from different sources. However, the pink one is not aligned properly. Any good ideas? Here's how to use the FME Clipper transformer to cut one polygon (subtract its area) from another. I need to do some checks on the parts that are not arcs. It assigns a templated output filename. i calculate the delta between the Z of the flat 3d polygon and the value in I have the same problem. Hi, I have a polygon layer that I need to split at every start and end point of a polyline layer. Firstly, I extract a closed polyline of LineOnAreaOverlayer Overlays lines and areas, intersecting geometry and sharing attributes. I have a single county parcel (polygon) . We have polygons that represents sections. shp files based on the value in the CITY field. The output I would look at points that share all three polygons, where one of the polygons is selected at a maximum size, then construct a line between Creating polygons in FME can be done by using polylines or line objects, and the AreaBuilder function. I am currently stuck on how to split the line at a point. And you can generate points at the ends Usage Notes If memory usage becomes an issue while using this transformer, try adding a RasterCheckpointer before the You should clip your polygon layers among them and keep the one with the highest value of your attribute. One way to reduce file sizes is to clip a raster to only an area of interest. Imagine one has area 100 units. shp) Hi everyone,I'm trying to replicate the "Explode" functionality of ArcGIS Pro in FME. I have tried Line Over Area Overlay, but no luck there. If the created line is closed, these Hi I have a road segment line/polyline dataset that I need to split for each segment object into 10m intervals and create a new record. Since the cycle route network Remnants receive an fme_remnant_type attribute with one of the following values: INTERIOR_LINE: The remnant is a portion of the input polygons I have 2 polygons, example 1 circle and 1 square. Jump to Configuration Typical Uses Creating donut polygons How does it work? Then the output is split into four output types (previously three output types in FME 2021. Then it clips all your Notice that FME has split the original single polygon features into a multi-part feature, consisting of several polygons/outlines: We now Introduction Rasters are often large datasets. Jump to Configuration Typical Uses Creating geometry for Divide the original lines into the first one and others. Jump to Configuration Typical Uses Creating polygons from linear features Hi, I have a dataset containing polygons with donuts. Alternatively you could also look at the Intersector, which is a bit more general. Is there any way for do this? My goal is to split the green polygon at the edge of the pink polygon. After that the PointOnLineOverlayer can split the polylines to lines with your created vertices. com/blog/2016/05/point-cloud-power/ so it splits the polygon into the number of parts or area I provide. I have not able to find a transformer to do so or any post So what is to be done? Well, the NeighbourFinder can tell you the closest line to each point. Only lines that split areas are considered for attribute The transformer will break your river line into multiple segments where your points intersects and will compute unique _edge_id I have a polygon that I want to split by a line feature. I have three line vectors in SHP format (Red, Yellow, and Green). For DonutBuilder Cuts holes in area features where they fully enclose another area, creating donut polygons. I need to remove these donuts as they are not allowed for further use of the dataset. g. Now i want to locate those polygons of shape A (polygon. Introduction The LineBuilder connects input point features in the order they enter, forming linear or polygonal features. The Explode tool in ArcGIS Pro breaks multipart geometries into Finding intersections between lines and polygons, and splitting the lines where they intersect with the polygons. Jump to Configuration Typical Uses CenterlineReplacer Replaces area geometry with its centerline or straight skeleton. For example, how polygons are Hi, Which combination of FME transformers would I need to use for splitting an irregular polygon into convex partitions (and possibly also minimizing I have a series of polygons which are overlapping. I am currently In this tutorial, you will create polygons for city blocks from a street network that consists of Arterial, Residential, Private, and Non-city 2014-09-06 Split Polygons Retaining Attributes I needed to split given land use polygons (Esri Shape format) according to actual land usage which I am using FME transformer PointOnLineOverlayer to split a line (formed by Road Elements) by Point (Traffic Sign), to do some further Yes, the Chopper breaks a polygon into lines if you set 2 or 3 to the "Maximum Vertices" parameter. Version: FME Desktop 2014 SP3 I have two shapes with polygons. Jump to Configuration Typical Uses Splitting lines where they I have road data and trying split line as equal parts or distance. In this demo we'll use a set of polygon features representing parks and a set of polygon features LineCombiner Connects line features that meet at common start or end points to create longer lines or paths. Jump to Configuration Typical Uses Creating areas from unclosed linear features How does it PointOnLineOverlayer Overlays points on lines, splitting lines and sharing attributes. las and so on. This can be To create a line, I usually use the 2D / 3DPointAdder or the PointConnector after creating points. e. Therefore I am using LineOnLine Overlayer in FME I need to further subdivide these parcels into sections that contain ~80km of line each while trying to maintain line connectivity as Hello everyone, I want to draw a polygon that crosses the 180th meridian and obtain this geometry (created manually, splitting the feature into two I am looking into using FME for performing data validation and quality assurance of some digitized line work. las, BY17_1401_split_2. However, at the endpoints these lines didn't extend to the edge of the polygons. These filtered hole polygons are then It will split polygons defined by lines, while transferring the attributes between those that intersect. I manage to The basic idea is to extract the holes using the extractor, calculate these polygon's areas and then do a test to exclude polygons above a defined size. DonutHoleExtractor Separates donut polygons into outer shell and hole polygons. they overlap, what transformer do I use to cut the overlap and leave the unoverlapped I have searched some methods to convert polygon into lines on FME. I need to dissolve a street feature class based on an Remnants receive an fme_remnant_type attribute with one of the following values: INTERIOR_LINE: The remnant is a portion of the input polygons I have some polygon features. . The solution works for both I have made center line dataset from polygons. quadrants. Do you know which transformation works in FME the same way as 'split line at point' in ArcGIS. safe. What's the best way to go about this? Thanks in Introduction A common GIS operation is to overlay two (or more) polygons to subtract the area of one polygon from another. The black line Creating polygons in FME can be accomplished by using a polyline or line features, such as a street network, and the AreaBuilder PathSplitter Splits path geometry into its component line and/or arc segments. We want to use FME to split all these polygons to subsections. Jump to Configuration Typical Uses Decomposing PathBuilder Finding intersections between lines and polygons, and splitting the lines where they intersect with the polygons. 2 or prior): Inside: All Candidate/Clippee Hello FME community, I am looking for ideas/ logic to use in FME to divide an irregular polygon geometry into user defined number of polygons of equal or approximately equal area. shp file that I need to break into several . Similarly I This post will detail a closed form solution to split polygons into any number of equal areas, while ensuring minimum length of line based cuts. So I I am stuck with a problem related to FME and hope you can help me sort it out. I need to split a network consisting of connected lines in FME by points. I need to break lines with the following rules: If the end of line A touches line B then break line b at that point If line If you zoom in you will see that there are lines in the Eastern Indo-Pacific polygons at 180°, but not in the Central Indo-Pacific polygon. 2m records) by an almost equally large dataset of polygon boudaries (~900k records). To the first line, give the first sort order attribute (e. Jump to Configuration Typical Uses Simplifying area geometry Snipper Shortens linear geometry by cutting off the ends. 0). Legal API Documentation Packages SDK Documentation FME Hub Status FAQs FME Hub Digest LineCloser Converts a linear feature to an area by connecting the end point to the start point. I have split them using the AreaOnAreaOverlayer to find the overlapping areas, and Clipper Divides Candidate features using Clipper features, so that Candidates and parts of Candidates that are inside or outside of the PointOnLineOverlayer Overlays points on lines, splitting lines and sharing attributes. As an alternative you can try to set the geometry to fme_line with the GeometryCoercer. Give 0-based segment number to other I am trying to intersect multiple line layers (in FME: feature types) against 1 layer. Jump to Configuration Typical Uses Connecting multiple lines into longer, The attched FFS file contains multi-geometry objects where one or more of the parts are arcs. How to do it in FME 2018?
