Detecting Digitization Direction Conflicts in Consecutive Lines

Hi everyone, I have a set of consecutive lines, and I need to detect when there is a digitization direction conflict between them. As shown in the image below, the green arrows represent the direction of my lines, but Line 2 is oriented differently compared to the others. Is there a way in FME to detect such conflicts? Ideally, I’d like to flag or filter out the lines that have a reversed direction compared to their neighbors.

Why do I need to reauthenticate Dropbox web connection everytime?

I have configured all parameters on manage web services for Dropbox. But I am having to reauthenticate every time I run the workspace. What should I be checking? I also need to schedule it on Server. I am not being able to authorize it on Server as well. Any feedback is highly appreciated.

Run multiple FMW files after each other

I’ve read a couple of posts on this, but I’m still not perfectly sure on how this works. I have over almost a year been working on and refining a flow. Since I keep getting new updates from the project, the flows has became large. It became into 3 flows, that could maybe have become 1, but I don’t think it would be that easy, at least I’m not up for that task. It consist of multiple feature readers and multiple feature writers. Each flow takes up some data from the other. For example something can have been made in a file Geodatabase or on ArcGIS Online, and the next flow would then use that content. So, I easily enough just want to run those 3 flows, by one click in workbench. I would expect just to create something like this. I just find it’s strange to connect it like that. Is it that easy?

How to apply an affixed transformation matrix?

I have different IFC files which I want to read and transform.The geometries each contain a Transformation Matrix. From the FME Form Documentation I know they are not applied. How can I apply them? I tried to extract the parameters (with TransformationMatrixExtractor) and then used the 3DAffiner, but with no result. Ther must be a more convenient way, right?!

Coordinate system extractor

I have a shapefile with a coordinate system defined which I'm using to test my workspace. I'm using the coordinate system extractor to check if there is a coordinate system. The _coordsys attribute comes up empty. But the shapefile does have a coordinate system. Why might this be happening?

AreaCalculator calculating different areas for the same feature

Hi all, I have a workspace that preps all input features by reprojecting them to GDA94/ Australian Albers and then calculates input area. When I run the same feature (as a shapefile, but different different coordinate systems) I get different Area values even though they’re both in the same Coordinate System. I ended up testing the features with an AreaOnAreaOverlayer and turns of there’s really tiny slivers across the boundary of the feature (I don’t know where these slivers are coming from?). I added both the shapefiles in ArcGIS Pro and followed the same process- reproject and calculate area and both area values are coming out as the same in Pro. I am unable to figure out why I’m getting this difference in areas in FME but not ArcGIS Pro. The difference is tiny but ends up changing the final stats. Screenshots attached. Any help would be greatly appreciated.

Autodesk Build connector

Is there a way to connect to Autodesk Build and retrieve photo's and Forms? Either through a connector or through the API. I can get acces to Autodesk Docs but I need acces to Build as I would like to add the photo's to a webmap. Because the API acces to ACC Build makes use of a three-legged authorization I see no possibility to do this. The process needs to allow for a pop-up and I don not know a way to avoid this. I hoped it was possible to use a webconnection in conjunction with an httpcaller but I do not know how. Does anybody have experience with this and perhaps an example?

Assistance needed with comparing location across two Datasets :

Dear All,I’m working with two datasets that share a common key: Station ID. Each dataset provides coordinates ( latitude and longitude) for these stations. My objective is to determine whether the station with the same ID have identical location in both datasets or if there are discrepancies. To achieve this, I need to calculate distance between the corresponding coordinates from both datasets. While this seems straightforward, but I encountering challenges in implementing it effectively. I would appreciate any help on the best approach. Thank you in advance. BR//

Geopacakge writer fanout causes issues with template file

Hi Everyone, I’m kind of stuck with a problem with my Geopackage writer. For a client, I’m working on building a script that generates multiple Geopackage tables, each with its own name. Each Geopackage table writer uses a fanout to automatically provide the writer with the needed file name. The writer also uses a Geopackage with styling embedded in the database, with 0 features, as a template file. This template is provided by an engineer from the team, which should automatically style the Geopackage based on the attributes it has. The problem occurs when I have both fanout and template file enabled. This causes the Geopackage to only write certain features. I can’t find any logic behind why it writes some features and not others. The template file and the Geopackage writer are 1-to-1 copies of each other, and I get no errors/warnings regarding feature issues. For example, one table, which consists of 470 features, will write 233 features, and 237 features end up somewhere in space. :

Custom Transformer - API Request with http caller in a loop, does not exist on time

Im fairly new to FME, I have a programming background, and I was hoping to bring those skill here, but i can see is not fully the same. So I apologize before hand 😂 I have a custom transformer that does a API calls and loops until it finds “last-batch” set to true from the Header area. For Reference Here is the custom transformer: The first call uses uses the InitialHTTPCaller, which uses the the request url and access token from the main workbench. Here is a screen cap: The _response_header list will have the variables I need to determine if the its the last-batch = true and the next batch url. The JSONFragmenter, is exposing the values for _response_header{5}.value,_response_header{6}.value. I have a tester that checks if _response_header(5) is true to go the pass else it will fail and will go to Output and call upon the Loop to the NextPage. When the NextHTTPCaller gets called it will be using the User Parameter named NextUrl of which im setting it with the @Value(_response_header{

Updating features through ArcGIS Portal Feature Service fails

Hi. I'm using the ArcGIS Portal Feature Service writer to do some inserts, updates and deletes on two feature services, one with line and one with points. The inserts and deletes works for both featureservices, but update on lines fails with the following error (operation rolled back for all of the features): ArcGIS Portal Feature Service Writer: Encountered an unexpected error. The error code from the server was '400' and the message was: 'Unable to complete operation.'. Details: 'Operation rolled back., Operation rolled back.... There are about 2000 features I need to update, so my best guess is that the jsonobject for update is too large. The update works fine with up to 200 features. What would be the best alternative for updating the line feature service? One way might be to create some kind of loop to update 200 lines at a time, but how?

ESRI ArcGIS Server Feature Service reader won't read feature type. Error - ArcGIS Feature Service Reader: Encountered an unexpected error. The error code from the server was '500' and the message was: 'Error performing query operation'. Details: ''

Hi, I have a workspace using an ESRI ArcGIS Server Feature Service reader with a token authentication. I am trying to read 3 feature types from the map server and 2 of them read fine but one comes back with the error: "ArcGIS Feature Service Reader: Encountered an unexpected error. The error code from the server was '500' and the message was: 'Error performing query operation'. Details: ''" Does anyone have any ideas of why only one of the feature types would not work? The three feature services should all have the same naming standards and schema so there is no reason why they should behave differently that I can see. Are there any suggestions for how I might be able to find the source of this issue? Any help would be greatly appreciated! Thanks.

Software updates - list of transformers that are affected

Hi, Does anyone know of a method where I can readily identify which transformers are affected (ie need an update / fixed / superseded!) when updating from one version to another? Whilst I know there is documentation with each release, is there an easy way to compile a list that could be read into a workbench? I am also aware that each transformer has a version number. I want to create a method for identifying which workbenches are going to break before updating the software! I am hoping someone has already thought of this and the solution is already built… Any help much appreciated. Stu

AGOL feature service writer not working correctly

Hi Im using the AGOL feature service writer to write to our AGOL account but it is not working correctly. The workbench reports that it has been successful with the correct number of features. However, when you open the item in AGOL, there are features missing. The last one I tried had 80k reported to have written but only 4k in AGOL! If I use write a fgdb locally and then the ‘ArcGIS Online Connector’ transformer to upload the file and another to publish it, it works fine. However, I cant work out how I could use this to do updates to the hosted feature service when the data changes (Ive got this sorted with the writer) Im using FME 2023.2 (dont really want to upgrade until 2025.1 is out as its a proper pain to upgrade server) but if there is an issue with the older version of this transformer I will. Does anyone know why the writer is not working but the connector is? This data is business critical so I need to ensure that it is correct. Thanks

What is the Roadmap to have the same file integrations for Mac Silicon as Mac Intel?

Unfortunately FME 2025 for Mac Silicon is still missing some file format integrations. What is the roadmap to get a complete collection of formats on the ARM plattform? I have had to resort to running an Intel version of FME on my Mac in order to be able to read File GDB and 2DPDF. (I don’t get to choose my source formats...). But it would be great to utilize the machines full potential, after all it was many years since Mac had an Intel in their line up.

Dynamically setting "Columns" on UPSERT in FeatureWriter to PostgreSQL

Hi, I have a dynamic workspace where I am reading in multiple csv update files for multiple feature types to upsert into our database. I had set the primary key dynamically dependent on the target table in the database. I cannot set a where clause on an UPSERT (which I do use with other feature types that have the ability to do I, U, or D) so went to use the "Row Selection: Columns:" section instead. This parameter does not work in the normal way with attributes. It presumes the selected attribute is the primary key field (no orange left arrow in front of the name), rather than using the value. I tried manually adding @Value(primary_key) (the attribute that stores the primary key column name) in the parameter but the feature writer also presumes it is literal and obviously can't find a column called "@Value(primary_key)" and errors. This is something that I would like to do, and is very much a part of a dynamic workflow. Otherwise I will have to create one dynamic feature writer for ea

SDE (Sql Server) Truncate Issues - FME fails to truncate table

Hi, I have a client that is experiencing some odd behavior when it comes to truncating feature classes and tables in a SQL Server SDE environment. The writer is set to 'Yes' for Truncate table however when fme writes out the features heading to the writer it does not truncate the data first but merely inserts data records. If i add a new reader, move the feature types over, configure it exactly the same and rerun the writer functions as expected (Truncate and Load data). Why do i have to add a new reader that is configured exactly the same to get FME to truncate properly. Do FME writers go stale? FME 2015.1 SDE (10.4.1) Any help will be apprecaited.

Any ideas for grouping the 25 neighbours to calculate the average distance? Thanks you all.
