maximum amount of non-neighbouring polygons

Trying to find a way to find the maximum amount (highest density) of polygons with the rulethe polygons must be non-neighbouring. Essentially selecting a polygon and jump to the next polygon which is not neighbouring and so fort and so on until you encounter a neighbouring one.See attached picture which I hand-picked.

REST API call from FME HTTPCaller gives an error of "HTTP/2 400" but from Postman it works fine

Hi All, I have FME Form 2023.2.I am trying to make a REST API call using HTTPCaller. I got this error below,{ "code": "data_validation_error", "message": "Invalid request values. Unexpected character ('_' (code 95)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')", "status": 400, "traceId": "240425163408767-2c15ec9a"}However, the same request works just fine on Postman. Not sure what exactly the error means here. Can anyone help me on this?Here is the HTTPCaller screenshot.Here is the request body, Here is the error messages from the Translation log.##########...UpdateRecordCustomTablesHTTPCaller (HTTPFactory): An error occurred while accessing the URL 'https://apis.accela.com/v4/records/PINELLAS-24CAP-00000-0004H/customTables'The below feature caused the translation to be terminatedStoring feature(s) to FME feature store file `C:\FME\Funeral Home\FuneralHomeBillingInterfacefmw_log.ffs'++++++++++++++++++++++++++++++++++++++++++++++++++++++

GDB Reader browsing slowness

We’re currently experience FME 2 minute+ freezes when we add an Esri GDB reader to a workbench, then press the ellipses to browse to the location. This only happens in the dialog if we have selected Esri Geodatabase (File Geodb) as the Format. We have found a work around of pasting the GDB path into the dialog box but we still experience a 30+ second pause when we hit Parameters/Tables. This takes a substantial time to load. The issue is decreased when a gdb reader is added to a brand new workbench.

Hi there,I have an Ascii grid file.The FME can read the file I have also added a Raster Cell Coercer transformer to create a shafile this simple workbench works fine. Issue - How the raster values can be displayed in the shapefile. The shapefile has no attribute data (cell values).I need to display the raster values in the shapefile. Any hints will be greatly appreciated.Thank you very much,Sebastian Algardi-CamusWorkbench Raster image

CSV content from SQL field to Features

Hi Community,I need to extract a CSV Style content from a SQL field of an SQL table.It is stored into a single field.The content looks like this:Classification,Fonction03-1,30003-2,301AA-10,C-1000AA-12,C-1000AA-15,C-1000AA-17,C-1000AA-20,C-1000AA-22,C-1000AA-25,C-1000AA-27,C-1000AA-30,C-1000As you can see, the first line gives me the Attributes names and the following lines gives me the valuesWhat would be the best way to turn this into multiple features using the first line as the Attributes names ?Thank you

Features do not display EPSG:3006

Hi,I use FME form through ArcGIS Data interoperability workbench and I work with the national Swedish coordinate system 3006 Sweref 99 tm. I cannot display these features with the standard background maps and get: This does not happen in the regular FME Form and they display without problem there. How can I solve this in ArcGIS DI workbench?Is the standard FME Form able to do some kind of on the fly reprojection to view the features on the standard base/background maps? Best regards,Karl

FilenameExtractor does not use value

I am trying to use the FilenameExtractor to get the rootname of the source file to match the new filename in a different source directory with a different format i.e. my pipeline is essentiallyMyFileName.xlsx → MyFileName.jsonCurrently if I use the source filename input paramter the behavior is like:MyFileName.xlsx → MyFileName.xlsx.json , which I don’t want.I tried using the FileNameExtractor where _rootname gets set as a user paramet but then the output is like:MyFileName.xlsx → _rootname.json The value of the user parameter does not actually extract the rootname and save its value as the user parameter dynamically. Can anyone help?edit:Scripted Python (safe.com)I used a scripted parameter at the start of the workspace but still curious as to why the filename extractor did not perform as expected?

PythonCaller exception doesn't print line number in 2024.0

In FME Flow 2024.0, when PythonCaller hits an Exception it doesn’t specify where the exception occurred -- we only get Message Type: fme::internal::_v0::py::ExceptionPython Exception <IndexError>: list index out of rangePythonCaller (PythonFactory): Group 28 / 20195: PythonFactory failed to process group properly However, there are numerous instances of indexing lists that could be responsible for this!Am I missing something? Is there anything I can do to fix this, or does Safe Software need to fix this? (How do I ask them to fix this, besides posting here?)

DEM Raster Feature class to JPEG

Good morning,I am reading a DEM stored as a raster feature class in a gdb, clipping to an AOI and then writing to JPEG to be used in road design software.I can read and clip properly but having trouble writing to JPEG. I have gathered I need to set up bands differently but I have tried the rasterbandinterpretationcoercer and rasterbandadder and rasterinterpretationcoecer in various configurations/settings and can’t seem to get it to write a JPEG. Usual error is about the number or type of bands depending on how I set the coercers etc.DEM raster feature information Any suggestions would be welcome.Thank you so much,Corey

How to use a SchemaScanner on an empty feature type?

FME(R) 2023.1.1.0 (20230928 - Build 23631 - WIN64)Hello FMEers,I have a set of Esri feature classes that we are supplying to our clients so they can submit data to us using a standard schema. On submission we want to verify they haven’t modified the data structure using the method described here. The method compares two datasets using the SchemaScanner and works well if there is at least one record in each feature type. It doesn’t work if there are no records in one of the datasets to be compared. This is expected because there are simply no features coming out of the ‘template’ feature class reader to work with.My question: is there any way to achieve the intent of the abovementioned article when one of my inputs has no records, only the table definition? The method works fine if I include a dummy record in the ‘template’ feature class, but I’d rather avoid this kludge.Thanks in advance.

Reading DWG with 2 transformers

At this moment I received a DWG drawing with both Extended and Object data. To convert this data I first have to read with:Autodesk AutoCAD Civil 3Dthen read withAutodesk AutoCAD Map 3D Object Dataand merge all features on the autocad_entity_handle Am I doing something wrong or is this the only way to get both attributes?Is it possible build a transformer that uses both reading engines because I think that would make the reader faster than current.

Aggregator removing projections?

Hello everyone,I am trying to write data into an SQL Database which contains multiple geometries (This is borehole location data containing the originaly measured location (point), a corrected location (point) an a borehole path (linestring)). After creating the geometries from fields and using a GeometryPropertySetter for each of these geometries I am using an Aggregator followed by a MultipleGeometrySetter-Transformer. This is working more or less as in 3 Geometries are in fact written into the database which then also contains 3 fields with SQL geometries as set by the 3 GeometryPropertySetters. But there seems to be a problem. Between setting the individual geometries and aggregation, all info on the previously set projections seems to be lost. Upon inspecting each individual GeometryPropertySetter all points are where they should be. Inspecting the following aggregator shows all points off bounds somewhere. It is my understanding that the aggregator should simply collect the input

Dynamic Reader keeps old feature type

I want to set up an FME workflow which I can reuse for projects, in which input data differs. For this, I want to load different shape files into FME using a parameter (the shapefilename). These shape files have different attribute names, so I wanted to use the schema mapper to map these different attributes.The problem is that I cannot get a dynamic reader to work properly (I used feature merge). When I load in the first shapefile for the first project, the reader sets the user attributes to the attribute names of the first shapefile . If I restart and load in the second shapefile , it won’t expose the attributes from the second shapefile (the attributes from the first shapefile remain!). How can I set up the reader to be able to handle different input schemes and change the exposed attributes dynamically, based on the input files?

PointOnPointOverlayer stores duplicates in list, how to read from Pythoncaller?

Problem in short:I have a lot of points which some has identical coordinates. PointOnPointOverlayer does this for me and store the “twins” in a list name. Now I want to use a Pythoncaller to loop through the list of each feature and figure out if some or none of the twin attributes has a value that should update the the major feature. The problem is that I cant seem to reach the list variable created in PointOnPointOverlayer from the Pythoncaller. It seems to be exposed when running with feature cache and checking output from PointOnPointOverlayer. What’s the magic for reading the list, looping throug it and check the attribute values? Tried this example code from the PythonCaller just to see if I could reach the list but can’t see anything:

Copy & Paste Transformer from file or web content

We generate certain types of transformers (mostly HTTPCaller) with some attributes prefilled and want our users to be able to copy the content from a file or web source and paste it directly into FME Workbench, or use drag and drop, if possible. We don’t want to use custom transformers, which works, but the overhead would be overkill. The problem is that the paste does not work, CTRL+V does nothing and the paste menu option is greyed out. I tried with a direct clone of a working transformer so the format is correct. If I copy a transformer, paste it into an editor, copy the editors content and try to paste it back to Workbench it won’t work. I don’t know why this does not work but I persume it might have something to do with encoding. Does anyone have a clue how to overcome this issue, or maybe a workaround? Thanks in advance.
