Avoiding overlaps and gaps when buffering line segments to polygons

I have line segments (vertex only a beginning and end) and want to create polygons for each (including their attributes).  The line segments represent a span between utility structures in a right of way. The goal is create the polygon geometry per span and calculate the acreage in each. The Bufferer works great when the line segments are straight, but when a turn is introduced, I get slivers and overlaps as seen in this screenshot:Notice the overlaps and slivers where the line turns Bufferer Parameters:Bufferer parameters To visualize what I’m trying to create - here is a mock up of where I want the polygons split (red lines were drawn in by me and the green polygon is just a buffer of the dissolved line segments).  The centerline represents the spans.Red lines = where I want the polygons split Doesn't sound too crazy but it’s kicking by butt at the moment.  Any idea or suggestions?

modify csv sheet

Hi, I have the following csv sheet created with FMEThat is not exactly what I want. I would like to see the following format:The third column is empty, and for the last 4 columns only 1 row is needed. How can I achieve that? The values in the last 4 columns are purely inserted in the user interface at the start, not more than that.Below is the part of FME:The user parameters of the writer  are as follows:Any tips?

Build 3d lines by overlaps on DTM: tuning

Hello everyone,I need to transform a 2D road graph into 3D. Each vertex of the lines should receive the correct Z value from a DTM.I found this solution, which works very well:  The problem with this workflow is that it is very slow. My region is very large: the graph has about 150,000 elements, and the vertex extractor generates more than 2,000,000 vertices, which slows down the script. Any suggestions?

Geocoding OpenStreetMap, How to adjust results to normalize

I am having some difficulty normalizing reverse geocodes for comparison from one Geocoding Service to another (in this case OpenStreetMap).  The _address that is returned can pretty easily split up into a list or separate attributes with most services as they are consistent. However, OSM’s _address has extra information and parsing it to be consistent with anything else has been a challenge.  See below where instead of having an AddressNumber, a null, or a 0, I get Falmouth Public Schools & Moonlight Meadery in the 1st position.  For that matter, I sometimes get supplementary place names such as Seaport & South Boston when expecting a Town in a particular separation/position.  So it throws off looking in any specific list due to the inconsistent placement.Some are normal, but many either don’t contain the expect info or add info that is unnecessary for my needs.What I want to make into attributes: AddressNumber  Street  Town  State  ZipCodeOpenStreetMap gives me this in a test.

HTML Extractor CSS Selector mapping document

Hello, I am trying to extract html tags from an attribute, however the documentation is very unclear and need further guidance.Page: https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Transformers/Transformers/htmlextractor.htmStates: “In the HTMLExtractor, a query is constructed to find the div tag with the id “article” (CSS Selector = #article). The contents of that tag will be extracted (Tag Part/HTML Attribute = Value), and output to the new attribute articleText.”Where is the mapping document that maps FME CSS selector ‘ids’ to html tags?  I am trying to extract <br>, what should the CSS selector for this be?  Using “br” as the selector and then using a list exploder produces an attribute with empty fields.

IFC_API Reader in FME 2025.1.1 fails to read features, reads Types only

Hello,I am currently learning how FME handles IFC HVAC structures and have been using some sample files from the RWTH-E3D DigitalHub repository (https://github.com/RWTH-E3D/DigitalHub) for my tests.While doing this, I'm having trouble getting FME to read all the features and their geometry correctly. The IFC file itself appears to be valid, as it displays correctly in an external IFC viewer like BimVision. (filename: DigitalHub_FM-HZG_v2.ifc)Here you can see the full HVAC system with pipes, tanks, pumps, etc.However, when I bring it into FME, I get incomplete results, and the behavior is different depending on the version I use.1. With FME(R) 2025.1.1.0 (Build 25615):The reader fails to read most features. The feature count for IfcPipeSegment, IfcTank, IfcPump, etc., is 0. The FME Inspector confirms that nothing is read.2. With FME(R) 2025.0.3.0 (Build 25241):This older version is partially successful:It correctly reads features like IfcPipeSegment and IfcTank with their geometry.Howev

StringSearch : use of non capturing group ?

I'd like to use non capturing groups in StringSearch. It is possible in the PCRE expression but seems not to work in FME :Example :On the string "This is a text string"(?:This is )(\\w)* should return only the string "a", but StringSearch returns the whole "This is a" in the "first_match", and only "a" in the subgroup when activated.First match should be the same as the first subset ?

GIS FC (FGDB) to Excel Spreadsheet

Hi folks,Trying my hand at a workflow that takes certain records from a GIS feature class and writes them into a Spreadsheet XLSX (2025 Work Plan). I’ve renamed the attributes from the GIS feature class schema to match the relevant fields in the 2025 Work Plan Spreadsheet with no issues. When I examine them, they look good in the table.The Spreadsheet has certain Excel-only fields that are not included in the GIS feature class. What I am finding is that while the information is being translated into the 2025 Work Plan Excel Sheet, it is also writing the remainder of the fields from the GIS feature class into columns in the 2025 Work Plan Excel Sheet that are Excel-only.This is despite trying to remove the excess fields in the Writer. And even mapping the fields directly to the corresponding fields in the Excel Writer. I had tried experimenting with the ‘Update’ parameter rather than Insert, but that caused errors.Are there any suggestions to ensure only the specified GIS fields are wri

How do I set the isNullable (Allow NULL) property for an attribute when writing to a feature class in an Esri SDE database?

In an Esri SDE database, fields (attributes) have a property setting of isNullable (Allow NULL). This property determines if the field allows null values or not. I want to be able to set this property in FME when I create a new feature class. Is there a way to set this property with the Esri Geodatabase SDE writer? See screenshot below to see how to set the setting in ArcGIS Pro.

Extract Campground site number information Question ?

Hi,I do have a question for anyone that experience about extracted information from a website . I have a geodatabase that I set it up as a field with Domains.The project I am working on is Campground for my Forest here we have many campgrounds.  I work on about 18 campground so far…My question is can I go to Recreation.gov site and select a campground using in FME ? For example, in the search box , type Colorado Campground and then it turns to new page and you will see the campground map that has all the Site number you can pick.So click on number three and then click View details...which will bring another page and it gives you all the information about that site number…That is what I plan to use this…I have done input all the information into my geodatabase  there. Will HTMLExtractor work for this type of thing ? Am I making myself clear  Thanks !

OneDrive single tenant web connection is approved but will not authenticate

filter data from fme_feature_type

Hello all! I am using a CSV file as a configuration source, which contains a list of database connections and corresponding table names. This CSV connects to a Feature Reader, where:The database connection is set using a parameter (dbConnection) read from the CSV. The feature types are dynamically set using the table names from the CSV.The Feature Reader successfully reads data from all specified tables and outputs them through a generic port. I’ve exposed both the feature attributes and the fme_feature_type.Now, I need to join the database data with client data, but since all table outputs are merged through a single port, it's difficult to manage and distinguish between them.What I’m looking for is a way to automatically separate the data by fme_feature_type (i.e., table name) and route each to a different port or stream without manually updating filters or Testers every time a new table is added to the CSV. This is essential because users will be updating the configuration file with

Automating Workflow with Multiple Shapefiles of Different Schemas

Hi everyone, I'm working on an FME workflow that needs to process multiple Shapefiles. The challenge is that these files come with different schemas (different attributes, attribute names, etc.). I’ve noticed that transformers like DuplicateFilter, AttributeExposer, DatetimeConverter, SchemaMapper... don’t handle these schema changes dynamically. That means every time a new Shapefile with a different schema is added, I have to manually update these transformers to accommodate the changes. Is there a way to make this process more dynamic, so the workflow can adapt automatically to different input schemas without manual intervention each time? Any tips or suggestions would be greatly appreciated! Thanks in advance!

Then I want to write all those shapefiles to a singe feature class in a geodatabase. How would I set up my featurereader so I can create and write that attribute in all those shapefiles before writing to the feature class?

XSD Driven XML Writer and _XML_FRAGEMENT_

Hi, I’m using XSDDrivenXMLWriter to write very dynamic XML to a file. There is one part of the xml with a lot of features that is very static and contains always the same data like origin and publisher… I don’t want to create all the 30 features with the XSDDrivenXMLWriter for this static part and thought I could use the _XML_FRAGMENT_ feature and 3 attributes like xml_fragment, xml_document_append_path and xml_document_append_as to tell the XSDDrivenXMLWriter to add my static xml to the output. But somehow I can’t get it working.Can you please provide me an example workspace? Unfortunately I cannot provide my workspace because it is restricted by the customer.Many thanks.

Don't read geometry, only attributes

Is it possible to only read the (selected) attributes, and not the geometry?Quite often, I need to join the attributes from two spatial datasets, but only need the geometry from one. And I am assuming that reading in only the selected attributes without geometry is noticeably faster than reading the attributes with geometry.Is it possible to read any dataset without geometry (other than reading it with and then doing a GeometryRemover)? And does this apply to all formats?

ArcObject Error while inserting rows in a feature class

Hi, I am getting this error:An error occurred while attempting to insert a row into the table ‘ABC’ using a cursor. The error number from ArcObjects is: '-2147217323'. The error message from ArcObjects is: {The cursor has been invalidated by an edit operation.} I am experiencing an issue when trying to insert features into a feature class stored in an enterprise geodatabase. Specifically, I am both reading from and writing to the same dataset. I haven't encountered this problem before, but it began after I set the Feature Operations to "Upsert" while updating existing records and inserting new records that are not yet present in the database. I suspect that performing inserts and updates simultaneously may be causing a disruption with the cursor. I also attempted to use the Feature holder, but I received the same error. This disruption is affecting the automated process. Does anyone know what might be causing this error or how to fix it? I would greatly appreciate any assistance!Thank
