Transformers

I wish to implement a filtering procedure for the vertices of each polyline. The goal is to retain only the vertices where the elevation difference between consecutive points exceeds a specified threshold, for example, 10 cm. I have developed a script that extracts all the vertices and identifies them based on the polyline to which they belong, as well as their specific index. The process involves testing the elevation difference between each pair of consecutive points. If this difference is below the threshold, the point should be eliminated, and the process moves on to the next point. Example of the process: If Z_PL1_1​​ − Z_PL1_2​​<0.1, then point PL1_2 should be eliminated. Next test: If Z_PL1_1​​ − Z_PL1_3​​>0.1, then the point PL1_3 is retained. Next we test PL1_3 with the other points of the polyline excluding PL1_2, and so on. This principle is applied iteratively to all polylines. Problem encountered: I am facing difficulty with the implementation of iterations to apply this l

I have a workspace which writes multiple tables to a single Geopackage. When running manually it works with no errors but when running via tasks scheduler it fails with the following error: OGCGEOPACKAGE writer: A file system object called '\\xxxx\output.gpkg' already exists.2025-02-10 07:35:51| 25.2| 0.0|ERROR |OGCGEOPACKAGE writer: Unable to open or create file '\\xxxx\output.gpkg'. Please ensure the specified file exists and is accessible2025-02-10 07:35:51| 25.2| 0.0|ERROR |OGCGEOPACKAGE writer: An error has occurred. Check the logfile above for details How can I avoid this happening? Is this happening because multiple writers trying to access the same GeoPackage file simultaneously, causing a conflict? Thank you!

Hello everyone, I am reaching out because I have run into a problem recently and searched through previous thread and couldn’t quite find my issue with a solution. I am running into a hang up when I run a workspace that triggers an additional workspace through FMEFlow using FMEFlowJobSubmitter. I will paste an example of what the log looks like. FMEFlowJobSubmitter: https://your.specific. - Submitting a request to run workspace 'Your-Workspace' in repository 'YourRepository'… FMEFlowJobSubmitter: https://your.specific - Failed to submit request to run workspace ''Your-Workspace'' in repository 'YourRepository'FMEFlowJobSubmitter - 'Failure when receiving data from the peer' My workflow is submitting around 70 jobs so after this error occurs around 15 times the error switches to: Error: Failed to update access token. FME Flow error: `FME Flow error: `929026:Error: Connection reset'' FMEFlowJobSubmitter: https://your.specific - Failed to submit request to run workspace ''Your-Workspace''

Is there any possibility to use an if statement similar to the xmlTemplater: https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/xmltemplater.htm The following code in the jsonTemplater returns the error "JSONTemplater_2(XMLTemplaterFactory): The following error occurred near line 2, column 50 of the query:JSONTemplater_2(XMLTemplaterFactory): invalid expression: syntax error, unexpected ExprSingle (missing comma "," between expressions?)" Suggestions and code samples would be very welcomed. { if (fme:get-attribute("IS_GRENZPUNKT") eq "1") then "1": {} else "2": {}}

I am getting some really strange results when trying to offset aggregated lines. The fat red lines below are aggregated. This is sent to an OffsetCurveGenerator, thin pink lines. In this instance it seems like the OffsetCurveGenerator treats the lines as individual parts and offsets them to different sides (I am looking at only left channel out here). In other cases it fuses the lines into unities that can not be restored afterwards with a Deaggregator. Any ideas on how to resolve this, or workarounds? Edit: I went back and checked the geometries in the examples below, there where to complaints in the GeometrValidator. This is a spinoff from my previous thread:

Hello, I have 4 excel documents hosted on SharePoint, I am using a FeatureReader taking in a temp download path. As can be seen the 4 items are being opened successfully in the featurereader, but the data is not grouped in any meaningful way for me to extract and sort out the various excel documents data (which is varying formatting, some have multiple tabs with differing data/headers between them, as you can see there are 14 schemas (total tabs within excel docs), and 1546 generic bits of data (total rows)) I’ve read that I can re-group the datasets by using fme_basename but I cannot work out how to expose this, I’ve found the post below, which offers suggestions of how to expose that data. But the solution it offers is not applicable, I am using version Does anyone know how I can expose the fme_basename? OR Is there a better way to do this?

Currently I have 23 CoG’s in an Azure Blob container and I want to retrieve only the area of those CoG’s covered by a rectangle that I use as the initiator for a FeatureReader. Unfortunately, the FeatureReader is reading first all the CoG’s in before making the decision where the bounding box is within, and then it returns the entire CoG, where I was rather expecting it would return the part the bounding box is covering. The CoG’s originate from the Copernicus DEM coverage GLO-30, contain overviews, etc… It takes almost 3 minutes for the FeatureReader to process the request. The bounding box is within a single CoG. When looking at the parameters for the COG reader, then I can see there is actually the possibility to set a search envelope. I could feed the bounding box to the envelope, which sadly is missing in the FeatureReader. Is there a way to speed things up? I only want to have the parts of the COG’s covered by the bounding box used as initiator, basically performing a range reque

Hi All, I’m using the JSONTemplater and I am getting the following errors from FME when it parses the root template: JSONTemplater (XMLTemplaterFactory): The following error occurred near line 81, column 59 of the query:JSONTemplater (XMLTemplaterFactory): "fme.get-attribute": function with arity 1 not declared In the root template, I have the following starting on line 80: "Subfeature1Array": [ fme:process-features("Subfeature-First", "xxxNumber", fme.get-attribute("xxxNumber")) ], "Subfeature2Array": [ fme:process-features("SecondFt", "xxxNumber", fme.get-attribute("xxxNumber")) ], "Subfeature3Array": [ fme:process-features("ThirdFeat", "xxxNumber", fme.get-attribute("xxxNumber")) ] Both the root features and the sub-features have an xxxNumber attribute. I am following what is documented in the Help for the JSONTemplater “Selecting the Sub-Features to Process” section example but have no clue what the issue is. Any help would be greatly appreciated!

I am using a WorkspaceRunner so that I can run multiple times the same FME workbench on different DNG separately. Just to be clear I will call the WorkspaceRunner to the workbench that runs the “child” workbench, and i will just call Workbench to the child workbench. I was all working fine the first times and now I find that some User Parameter (in my case “DNG”) I was “sending” from the WorkspaceRunner to the Workbench is not working anymore (I didn’t change the parameter in the WorkspaceRunner but maybe i used it in more places inside my Workbench). When I run it directly inside my Workbench it makes no problem. But when I run it from the workspacerunner the following error appears: ERROR : Undefined macro `DGN' dereferenced in file `G:\Buzon\Miguel\CQ_topologia_copia\wb-xlate-1738321227449_8672' I think the wb-xlate is a temporary file of some sort. I have a wb-xlate in the root of the project but not the name does not match the one appearing here. That wb-xlate actually contains th

Hello Everyone, I am trying to use RCaller in FME 2024.1.3.0 with R version 4.3.3. To get started, I followed the tutorials, but in every case, the script gets stuck at RCaller. There are no errors or warnings—it simply does nothing and keeps running indefinitely. The last thing I see is: It seems that the connection to R.exe is working. Does anyone know what beginner mistake I might be making?

Hi All, Need your help fix the below scenario, I have a dataset approximately 100,000 records and these records have Polygon geometry I am using "aggregator" transformer to group the records as per column attribute and it creates 100 aggregated records. My requirement is to show each aggregated record as 1 shape on the map when user clicks on it. Issue: I am facing issue with geometry aggregation. When I plot data on ArcGIS online, I see all 100 aggregated records, but see some empty spots on the map.If I plot the same data on map without aggregating it, it plots fine. looks like something is going wrong with geometry aggregation. Would really appreciate if you could provide some input on how to handle it. Below is the configuration of my Aggregator transformer, Thanks,

I’ve got a test filter with about 12 different output ports. My goal is to unfilter all of these but have an attribute of “test result” and the value set to which output port the feature filtered through. Is there a way to expose the output port name? I know I could add attribute creators after each port or set one with a conditional statement but was hoping there was an easier way.

I am using FME Form 2021. I have been running two workspaces for about a year now. These upload spreadsheets to an SFTP site. Every once in a while, I get this error message: The FTPCaller Error Message from the Rejected Port: Error in the SSH layer This error prevents the spreadsheets from being uploaded to the SFTP site. Usually, the error seems to go away after a few days with nothing done on my end, and then the workspaces run normally. There does not seem to be a pattern of when the error is received. I checked the Log Files, and they show nothing unusual. I checked with our IT Network Admins, and they say nothing is blocking files from being uploaded to the SFTP Site. Here is a screenshot of the parameters in the FTPCaller Transformer I use: Questions: What is the cause of this error? Could the error be on the side of the folks who manage the SFTP site? (outside my organization) Is it a bug in FME Form 2021? Is this error received when using FTPCaller Transformer in FME Form 2024

Hi, our ArcMap license will expired tomrrow and will not renew after it expired. Also, I have Arcgis pro installed on my machine and the license is valid (will not expire). Currently all of my script setting is set AUTO under the “Esri ArcGIS Compatibility” . Will the AUTO setting pick to ArcGIS Pro license, after ArcMap license is expired? or do i have to manually set to ArcGIS Pro in each FMW script individually? “FME Workspace, go to Navigator --> Workspace Parameter --> Translation --> Esri ArcGIS Compatibility --> AUTO” thanks, Wilson

I have been checking a lot on this link but its not exactly what I want. Combine overlapping/touching lines into one long simple geometric line | Community I have one geopackage with lines of different types that overlap, 2 attribute types, the blue type and the red. As you can see they overlap. I want the red lines to take priority, meaning where the red lines are the underlying blue lines should be remove so I only have 1 layer of polygons with the 2 types. Note that the length of the blue line doesn’t always match the length of the red so the underlying blue line have to be cut. I have filtrered them, tried line combiner, line on line overlay which generates INVALID_POLYGON_GEOMETRY_VERTICES error. Reader polylines with attributes TestFilter, filters and splits the 2 types I want based on the type name ???
