Geojson file - how to copy the array of features to a new Geojson file?

I am new to FME. I have a geojson file with an array of features - for example under functionalClass i have 6 different modes of transport and under category I have 5 different types of roads. I want to create a new geojson file but using an existing geopackage (with only the attribute field called roadName as a value) but I need the new geojson file to have the same array of features as the first one. What would be the best way to create this? I have consider the feature readers and writers, JsonTemplater and JsonFormatter. But I am a bit lost on where to start or what transformer is the best to use in this case? Or is there an easy way to extract the arrays in FME so I can build csv files and just map them using an attributemapper transformer? Thank you for your time.

probems with DGN custom lines

Hello everyone,At the moment I am doing a conversion from BGT to NLCS (Dutch cad standard)I have an excel file (bgt to nlcs conversion) which has the corresponding color, line weight and linestyle names that I need for the conversion to NLCS.I have created a seedfile and via the Line style editor in Microstation 2023 I imported the rsc files that I needed in the seedfile.In fme, I don't use the dgnstyler, but I just defined the following attributes in the Attibutemanager:igds_style_nameigds_colorigds_weightIn the Level manager in the seed file, I haven't defined the levelname and the corresponding style yet, since it would be too much work for me. So based on Fme I just hope to give elements their corresponding color, lineweight and style. Color and weight has been succesfully (see below for snapshot of the output in the data inspector), only igds_style_name not yet. I haven’t used igds_style, since I don't know the number and I have the igds_style_name available in the excel file, so

FTPCaller - Protocols and algorithms for SFTP

We are in the process of building a new FME workspace that is using the FTPCaller transformer to upload a file to a remote SFTP server. To ensure we are compliant with our internal security standards around cryptography, I am looking into SSH protocol versions and cryptographic algorithms in use by the FTPCaller transformer.My questions are:Which versions of the SSH protocol does the FTPCaller support? I know from connecting to a local SSH-2-only SSH server that it supports SSH-2, but does it also support SSH-1? (I hope not!) Is there any way of configuring the cryptographic algorithms used by the FTPCaller? Or, as an alternative, listing the supported/enabled algorithms?Thank you,Jonathan

How to take only the latest data from an API that updates every week?

Hi Im reading an API with health data that updates every week. The goal is to aumomatize the process so FME reads this API every week to take out the new data. Now this API has an attribute called “temporal” which has values like this: “2024-W30” or “2020-W10” which is just the year and the calendar week. The data goes back several years and each week the last week gets added.I only want to use the latest data each week so what I need is somekind of a filter that looks at the attribute “temporal” and only takes the data from the current year with the highest numbered week which corresponds to the data that got added last week. Any suggestions on how I could do this? Thanks in advance

FTP/FTPS/SFTP transfer error: Failed initialization

I know this question have been asked few years back but unable to find its answer in the same thread today. I am using FTPCaller to download files from a remote SFTP server, I got logging in cridentials from the SFTP server admin and my computer is allowed to login to the SFTP server; which means there is no problem with connection and previledges. But FTPCallers responds with failed Initialization! any suggestion? Thank you!

Calculate polygons angles to horizon

I have a lot of polygons that represent buildings and I want to rasterise them but before I do I need all the polygons to be parallel to the horizon. I need to create a tool that calculates the polygon angles and then use these angles to rotate the buildings accordingly.

JSON-Templater- null values

Good day,I am using a JSON-Templater.My Root Template looks like this:{"GisData": {"Lake" : [fme:process-features("LAKE")], "River" : [fme:process-features("RIVER")], "Park : [fme:process-features("PARK")] } }and in the Sub Template I have one port for the Lake, one for the River and one for the Park.In some cases I don’t have lakes for the JSON I want to create. So the JSON will look like this: "Lake": [], This is not useful and will create issues later on. How can I specify that I only want to add them to the JSON if they have a value ?

AttributeTrimmer is trimming only 1 character (bug introduced with transformer version 4)

Hi,the AttributeTrimmer transformer does no longer trim correctly after updating from transformer version 3 to version 4.In my workspace I use the AttributeTrimmer to strip whitespaces from attributes. This used to work as intended and as described in documentation. It stripped all whitespace characters from the attributes, regardless how many there are. Recently I upgraded this transformer from version 3 to version 4. The new version works differently after that. Now it strips only 1 whitespace. When there are more of them at the beginning or end of the attribute the rest of them is left untouched (i.e. if there were 3 whitespaces at the end of a string entering the transformer, the result still has 2 whitespaces at the end).This seems to be not working as intended and described in documentation and should be changed in a future version. I use this transformer a lot to clean up attributes for comparison.Can someone else confirm this problem?Kind regards,Andras

Using parameters to only read one specified feature service

Hi all,I’d like to use a FeatureReader transformer to read in an ArcGIS Feature Server and then have a user specify which specific Feature Service they would like to process. The Feature Server has ~15 services whose names I have added into a parameter. I added the parameter to the “Feature Types to Read” option, but can’t get the tool to successfully read in the service that I specify. I attached a screencap of how I have things set up so far...does anyone know how I can accomplish this? I think I’m close and might just be missing something small.

Sharepoint connection without online template

I’m having a workspace with some connections to files that are on sharepoint. I did create the correct setup with the web connections to have a sharepoint account with client & tenant id etc in it. workspace works fine at my side, but the account that was provided is an account that has access to a lot off stuff.When I want to share the workspace with production so that they can run it, they also need to have the webconnection present in their workbench to get it to work (otherwise sharepoint online connector turns red etc).With this they can actually access more files than what is stricly needed (even though my workspace is password protected, nothing stops them from using that account for fetching different files) and this may lead to security issues.Although using a account with limited access to files on sharepoint would also help, I’m wondering if there is a different way to access files from sharepoint? I’m comparing it a bit with database connections:Connections are convenie

Behaviour of mesh and appearance

Hi, Can someone explain the following behaviour?Goal: create one mesh with each surface as a ‘flat’ color’ without shading. Problem: I get a shading effect that I do not want after merging many faces into one mesh. Images are attached. The first image is correct, it shows each side as one flat shading of the color #c8c8c8 (200, 200, 200). This is when I applied that as appearance to each single part (40.000). After merging all these 40.000 Faces or Meshes into 1 mesh, a new shading is applied that is undesired. I use MeshMerger with default settings. Can someone explain to me why this is happening and how I can prevent this to happen? If I re-apply the appearance to the single mesh it still gets the shading. Why is this happening? Where is it coming from? I also tried using appearance from a single jpg with the solid color, but this also did not work. Thanks.

String functions on FME 2024 don't work similarly with FME 2023

I find that the string functions on FME2024 don’t work similarly in FME 2023, in this case, it led to some problems with the outcome as not expected. Example:I have 2 strings:“EMD-1” “ÊMĐ-1”I use string functions as below: I received 2 outcomes differently:With the text 1: Count_index = 4With the text 2: Count_index = 6It is not right, in FME 2023 the outcome is 4 for both situations.Is this a bug in FME2024 ?

SQLCreator errors out even though results are returned

Hello,I have just upgraded to FME 2024.1 (was originally using FME 2022) and when running an SQLCreator using ODBC3.x I get an error, this was working just fine when using FME 2022.What’s strange is that even though I receive an error, all expected features are semi-cached and observable in the translation view as shown in the picture, the problem is that I can’t continue to run the following transformers as FME is taking it that the SQLCreator failed.Does anyone have any advice on how to get around this? My SQL code is fairly simple, just pinging an Azure database and doing some basic joins (the code also works fine when running on Azure Data Studio). Thank you!

Where is the FME User manual

I am using the FME objects python API including the FMEUniversalReader. fmeobjects.FMEUniversalReader — Python FME API FME 2024.1 b24615 documentation (safe.com)In the documentation for this API it says to pass “Reader’s type mneumonic as found in the FME Reference Manual Part II” but the reference manual isn’t linked.It isn’t in the admin guide: FME Desktop Administrator's Guide (safe.com)And Safe Docs just link back to the python API Search (safe.com) which doesn’t actually tell me the mneumonics.When I pass it’s reference in the UI for FME Form I get this error in my python caller.This FME edition does not recognize the `ARCSDE GEODB' reader. Please ensure that the current platform supports this reader, the reader name is spelled correctly, and that you have installed all required plug-insThe reason I am doing is because of this issue; AreaonAreaOverlay with intersecting features | Community (safe.com) and using the python caller seems like the best median to keep this in FME.

Attribute filter by filename contains 'text'

I have a glut of features of multiple types coming in from a handful of .ifc files. I am attempting to write a transformer as a proof of concept that will allow me to filter the features (currently 174000+) to different writers based on a small difference within their source filenames. Basically what I want to know is if it is possible to use the text editor to create an “if filename contains text (abc)” filter. If not, what would be the best way to filter for something like this.

How to run FMETransformer in pythoncaller

I need to use the PythonCaller because the area on area overlayer doesn’t work with my input featureset. I want each polygon in featureset A to overlay against all the polygons in Featureset B (which does not self intersect) and then drop overlays with NA values in specific columns. I found documentation for the fmeobjects.PythonCaller, but the documentation doesn’t include how to actually run the transformer.fmeobjects.FMETransformer — Python FME API FME 2024.1 b24615 documentation (safe.com)i.e. what do I do with f = fmeobjects.FMETransformer after I’ve set the attributes?Additionally, it’s unclear what the parameters are for this object, as there is no function definition returned to define what is required for each transformer type.AreaOnAreaOverlayer (safe.com)Related questions:AreaonAreaOverlay with intersecting features | Community (safe.com)Where is the FME User manual | Community (safe.com)

How to Quickly Rename Referenced Attributes in Multiple Transformers

I have a complex workflow where a specific attributes, i.e. “PositionID”, which are referenced across multiple transformers. I need to rename these attributes to another name throughout the entire workflow. Manually opening each transformer to change the reference would be very time-consuming.Is there a way to quickly rename this attribute in all transformers without having to edit each one individually? Any tips or tools within FME that can help streamline this process would be greatly appreciated.Alternatively, next time I create a project can I set these up as parameters or variables and reference them that way and hence change them more easily? Thanks
