AIXM 5.1 geometry from AirspaceTimeSlice not loaded when referenced with xlink:href

I use the AIXM 5.1 Reader with the default settings to read all AirspaceTimeSlice. Some of them are missing geometry. For example, I have a feature which uses xlink:href to reference the geometry of a CTR. The CTR in itself has an UNION and consists of two CTR's which are also referenced with xlink:href. How can I get FME to get this geometry. It somehow doesn't seem to follow up on the xlink:href. I use FME Desktop 2019.2.3.1

Count

I have a layer that contains 2 point line features i.e. start and end only, and I want to convert the start and end to points but have a count that keeps the parts in order. For example the start of the first line has count of 1 and the end of that line a count of 2, then the next line, start point would be 3 and end point would be 4. Each line has an ID so was thinking to try and group the points by line ID and then apply the count but can’t get the grouping to work as expected.

Navisworks BIM data conversion

I'm looking for support with Navisworks (AutoDesk) BIM data (.nwd .nwf .nwc). I need to extract the full 6D information from the model and output it to other formats but also update the 6D information back to the model. Navisworks imports IFC but does not seem to export it. DWF, which can be written with Navisworks, does not hold the 6D information.Any help would be appreciated.

Spike Detector?

I have a dataset with spikes, and I want to flag records with spikes for manual inspection.I am aware of the SpikeRemover transformer. Is there a method of just detecting spikes? Not removing them but just flagging them? I would prefer to do a manual fix.

Scan QR-code within workspace, is there a way?

Wondering if FME can read QR-codes from images. Input is folder with images with QR-codes and some other content. FME should determine where to save those files based on the QR-code so just be able to read the code within workspace. Has anyone tried doing something like this?

StringSearcher list unexposed in FME Flow

However, when I publish the workbench to FME Flow, the list isn’t exposed and cannot be accessed.

_feature_types{*}.name

I have a featurereader after a featurewriter which is writing 4 feature types. I have configured the dataset parameter as _dataset as per the output of the reader. What do i need as the feature types to read? I have tried _feature_types{0}.name _feature_types{1}.name _feature_types{2}.name _feature_types{3}.name and _feature_types{*}.name but neither work. _feature_types{0}.name by itself does work on the first of the 4 in that same parameter.

StringPairReplacer with dynamic input

Hello everyone,I am using the StringPairReplacer to find and replace short codes with their corresponding fulltext from a string that may contain multiple codes. It looks something like thisA1, A2(A3), A4 → Fulltext1, Fulltext2(Fulltext3), Fulltext4with the Replacement Pairs: A1 Fulltext1 A2 Fulltext2 A3 Fulltext4 A4 Fulltext4 This works fine, however the lookup table containing codes-fulltext translations may change in the future and I would like to implement a dynamic solution which doesnt rely on changing the workspace everytime something changes in the translation. I managed to create the correct text for the replacement pairs field using the SQL Creator from my translation database but am having trouble inserting this string into the appropriate field as it only accepts text and user parameter input. I am not too familiar with user parameters and cant seem to work out a solution to insert the dynamically created string into the StringPairReplacer.Does anyone have an idea how to do

Search for partial match of names in two different datasets

Hello,I would like to use FME to search for partial name matches (essentially a fuzzy string comparison) between two columns in different datasets.The challenge I'm facing is that it’s not a straightforward ID-based comparison. I want to pick a name from a row in one dataset and search for the closest match in a column of names in another dataset.Does anyone know a way to achieve this in FME, perhaps without relying on IDs?Thank you!

FME 2024.1 SharePoint Reader

I have a workspace created in 2023.2 that reads an Excel workbook from a SharePoint library. It is working perfectly.I have upgraded to 2024.1 and the reader no longer works as expected. If I use the 2024 Data Inspector I can connect to the workbook and see the data. The FeatureReader obtains the schema and the number of records in each sheet and gives a “Translation was SUCCESSFUL” in the log. The issue happens after that - I get some sort of (possibly) Python related error. Log file of messages after the successful log entry is attached.I have tried changing the Python version but it didn’t make any difference. Has anyone had the same issue or any ideas what I could try to get it working again.

Drone image footprint calculation

Hi, We would like to be able to calculate the real world footprint of drone images to result as a trapezoid polygon. This should be possible with only the exifdata that we get from the custom transformer "exifReader" as far as I can tell. I found a python version here, but it requires additional installation of vector3d from the python script. Anyone got a solution to calculate drone image footprints?https://gist.github.com/luipir/dc33864b53cf6634f9cdd2bce712d3d9 The custom transformer FootprintCreator promises something similar but requires a CSV-file from the camera. Anyone got a suggestion/solution? It would be a neat transformer that I think a lot of people would benefit from. We have a couple of different DJI drones.

replace substrings based on a lookup table

I am trying to find a functionality within FME that allows me to replace substrings based on a lookup table. Since I have several hundred mappings, chaining string replacers together isn’t really an option.Basically something like an AttributeValueMapper that looks at substrings instead of the whole value only or a string replacer that accepts multiple string/replacement inputs.Is there such a transformer or any workaround to do this?Thank you!

Create new attribute using parameter name

Good day,I have the following parameters in my script:AVE_AVENUEBLVD_BOULEVARDCTR_CENTREPL_PLACERD_ROADEach parameter is set up as a choice, when running the script you have the option to chose YES or NO for each parameter.Later in the script I want to retrieve the parameters for which YES has been chosen. I want to create a new attribute whose value is a list of the parameter names (keep only the letters before the underscore). Let’s say AVE_AVENUE, BLVD_BOULEVARD and CTR_CENTRE are set to YES ; PL_PLACE and RD_ROAD are set to NO. A new attribute called “address” is created and its value should be: ‘AVE’, ‘BLVD’, ‘CTR’. How can I do so ? Thanks for your help.

Problem using FeatureReader with ArcGIS Portal Feature Service

I’m trying to use the FeatureReader to read 3 features from an ArcGIS portal feature service layer by reading in a spreadsheet and using a WHERE clause with an attribute in the spreadsheet. The FeatureReader will connect to the service and I can select the correct table in the “Feature Types to Read” parameter. But when I try to add the WHERE clause FME crashes before I can start creating the WHERE clause. The second image below indicated the point when it crashes.I can read the full table with no problem using the ArcGIS Portal Feature Service reader. How can I get the FeatureReader to run and read the required features?
