How to change NaN to NoData?

I have a workflow where I am creating a raster using SurfaceModeler. As documented, this transformer may output some NaN values when using PLANAR interpolation. I indeed have a few cells that come out with a NaN value. I am not certain what transformer can change my NaN values to NoData values (or any other values)? I read through this article: http://blog.safe.com/2013/11/fmeevangelist119/ and thought the NullAttributeMapper would be the answer, but it does not seem so.

How do I get FME to select the right cert for Client Cert Authentication to server?

Part of the handshake is described as:Upon receiving the Server Hello containing the Client Certificate request & list of Distinguished CA names, the client will perform the following steps:The client uses the CA list available in the SERVER HELLO to determine the mutually trusted CA certificates.The client will then determine the Client Certificates that have been issued by the mutually trusted Certification Authorities.The client will then present the client certificate list to the user so that they can select a certificate to be sent to the Server.So the last part of this states the cert list is provided to the user so they can select the cert to sent to the server. In this case the user is FME. How does it select which cert to pass to the server?

Fitview when writing to microstation dgn

I am using FME to write to microstation DGN. The FME workbench file is using the fanout option to write different areas to the microstation DGN file, based on the same seed file. At the moment I have to use a microstation macro to "fitview" of each produced file in order to have the microstation file centered at each specific area. I rather use only FME to avoid this additonal step.Is there a way / transformer in FME to save the microstation file centered in the written data?

Can Writer Esri Geodatabase (File Geodb Open API) write metadata?

Hello all,I have succeeded in building a workspace that Reads from Oracle and Writes a fileGDB that includes metadata for the feature layer in the fileGDB. I used an XMLTemplater to achieve this.I am successful when I use the Writer Esri Geodatabase (File Geodb)However, I would prefer to use the Writer Esri Geodatabase (File Geodb Open API)But when I substitute this Writer, it fails to include the metadata for the feature layer.Is there some setting that I am missing?Or is this functionality just missing from the Open API Writer?

RAPIDS conda environment for FME Form and Flow under Linux?

I have a need to access some advanced graph algorithms in the RAPIDS (rapids.ai) package from a PythonCaller, which is normally installed as a Conda environment. I have found a few references on selecting the Conda-environment-specific Python interpreter, but unfortunately, they all assume we are running under Windows. We are running Ubuntu Linux, and the Linux installation of FME Form (as well as the macOS installation) doesn’t support custom interpreters.Any ideas on how I can get around this? I’ve previously managed to install pip packages into the standard FME interpreter environment with no issues, but it’s very difficult to successfully install RAPIDS using pip due to its many binary dependencies.

Deleting a folder/file at Beginning of Workbench

I have created a series of workbenches that populate an ESRI File Geodatabase. Each workbench corresponds to an individual feature dataset. I have created a workbench with Workspace Runners for each of the individual workbenches so I can run them from there instead of individually.I have used a schemaScanner in the individual workbenches because the schema may change on the incoming datasets without my knowledge. For this reason I had set the first workbench run to overwrite the geodatabase instead of truncate to account for schema changes when doing geodatabase updates. However when I try to run it, I get an error that the geodatabase is locked. To get around this, at the beginning of the workbench I’d like to delete the existing geodatabase and then run each of the workbenches to recreate it. To do this I have read I should move the geodatabase to a temporary folder that FME will then delete at the end of the workbench run. I am have used the temp path creator to create an attribute

Finding matching records between two datasets based on a specifed attribute

Hello Forum, I need to find the records from one dataset where the value in one of its attributes is the same as the value of an attribute in another dataset. For example, If I have two datasets (A and B) I want the output to show which records in A have shared value in B, based on a specified attribute. I want the output to be a selection of A. Something like this… I’ve tried Matcher, but that didn’t work for me. Thanks,Stuart

Where is the "recover" file if Form crashed before it's named and saved?

I remember back in 2021 when this happened, someone from Safe was able to point me to where the “recover” file was saved. Please help me again as i have created a very robust workspace but have not saved it and it would take me 3 hrs to recreate this workspace

ArcGIS Online Writer - Restoring a feature service when error encountered

I’m a newby to FME.I’m about to write workspaces to refresh a list of AGOL feature services. So far I’ve written a simple one that works on a small service.I’ve got a few questions.When I search for potential pitfalls in this forum, they are 5+ years ago and relate to AGOL time outs and also issues updating large datasets. . I’m on the latest release of Form & will use Flow (Hosted). Are these issues still relevant these days ?My largest dataset is our Cadastre being about 140K features. Am I safe to use the Writer ? I am doing truncate & inserts. One might argue that I could use ChangeDetector beforehand, however, I reckon the processing required to compare 140K features would be greater than a simple truncate & insert. (am I right?) If an error is encountered, I would like to quickly restore the destination feature service back to what it was. Any tips on the best approach to doing that ? My idea is to copy the destination service elsewhere in AGOL before commencin

Writer configuration for Excel

I have an excel file with 100 records (100 rows) with 5 columns. I have a process that will filter one record to update one column field called ‘Last Update’ in that particular record row. So The column ‘Last Update’ for that 1 record should be updated and the rest of the 99 records will remain the same. Keep in mind that the one record being updated, only one column is to be updated which is the Last Update column and the rest of the columns fields will remain the same. How can I configure the FeatureWriter?I currently have the following set in the FeatureWriter Parameters and in the configuration but this does nothing. The excel sheet looks the same as before with all 100 records the same and the one record that Im looking to update does not have the Last Update column updated. If I do an Insert, it updates that one record column ‘Last Update’ but the rest of the 99 records are deleted, which I don’t want. So the Insert is not working for my purpose.Thank you.

Reader aborts reading complete data set, but workbench continues to run. Can I have the workbench fail when this occurs?

I have an FME workbench that runs every 10 minutes that reads from an ESRI Feature class in a SQL database. Once in a blue moon I get the following warnings.Unable to retrieve feature from table/feature class 'xxx'. This feature, and any other feature from 'xxx' that cannot be read, will be skipped. The error number from ArcObjects is: '-2147154945'Unable to retrieve feature from table/feature class 'xxx'. Aborting reading from table 'xxx'. The error number from ArcObjects is: '-2147216010' Yet the next run 10 minutes later has no problems. When this occurs I want the workbench to stop rather than proceeding with the incomplete data set. Is there a way to force a termination when this happens?

Merge polygons with gaps

I have several polygons. They follow a line pattern where tre long polygons should be one large, and by that i mean that there should be no space between them, and instead of three long polygons it should be one large. The following image shows three pairs, so these nine polygons should be three larger polygons. Any idea how to do this?

Spatial Filter - disjoint unexpected result

I need to find lines which are completely outside polygonsI am using the Spatialfilter with “Filter is OGC-Disjoint From Candidate”. All of them pass and I dont understand why?Current workflow This is my dummy data i am using. As you can see, the line highlighted with the red box is clearly the only line disjointed from the polygon. So why does all candidate pass, it make no sense to me? What form of transformer should i use if what I do is wrong? Its obvious to me that it qualifies os OGC disjoint?https://docs.safe.com/fme/2023.2/html/FME-Form-Documentation/FME-Transformers/Transformers/spatialrelations.htm

Is it possible to return FME 24 to a Classic View?

I’ve been dabbling in the latest release of FME Form 2024 for a little while now and I’m just not getting the benefits of the new look, specifically the removal of colour from most icons.I could go into personal reasons why colour helps myself with attention to detail, concentration and focus but I’m just wondering if it’s possible to get a classic look while utilising any new functionality.

Unable to select Google BigQuery as a writer

I’m working through a test case to pull a table data from one of our MS SQL databases into Google BigQuery. I’ve downloaded and installed the BigQuery package from FME Hub and setup the needed Clientid and secret to have it connect to our Google Cloud project. It tests successfully in the services setup, and if I use the GoogleBigQueryConnector, I’m able to select our cloud project and dataset for reading, so I know the connectivity part of it is working. The issue is trying to write something to BigQuery.If I go to create a writer and choose “Google BigQuery” as the format, the Format selection stays red, like it’s an invalid selection.

Extracting workspace metadata

Hi, I’m working on automating our FME workspace deployment on Azure Devops using the functionality in pipelines. One thing I would like to automate is to extract metadata about every workspace pushed to the repository and write it to a README.md file. With such a file placed next to every workspace it would be easier to navigate our repo. I would like to see basic information like workspace name, description, number of transformers etc.What’s the best way to extract this data? I have tried using python to read the .fmw text directly and using the FME workspace reader with partial success. Has anyone else done something similar or have ideas?
