I would like to know how I can transfer z-coordinates from nearest neighbour point features to all the vertices of a polyline in such a way that each vertex gets a unique z (so multiple unique z's per polyline)?

The Z-coordinates are not the same and varying. The points are located within a buffer of 0.1meter and extend over the entire area of the polyline. I have to join them based on a search area I think of 0.1 meters. The points are created from a las and transformed using the pointcloudtopointcourcer. As an example, I would like to have for this polyline which has 5 vertices 5 unique z-values from the closest points.

How can I calculate perpendicular angles of a line at points along that line and apply the angle value to each point?

I have a highway line feature class and a highway distance markers point feature class with points created at 2km intervals along each highway line. I am being requested to create a rotation value to apply to each point on the line that is equal to the perpendicular angle on that line at each point. This angle value will then be used to apply label rotations to ensure each label comes out perpendicular to the line feature it is on.

DataUpdater not updating Oracle non spatial table

Hi, has anyone had an issue with updating a non-spatial Oracle (19) table. The table has been registered in SDE, hence has OBJECTID also.There is no failure, but the record is not updated. If I use an SDE writer with update operation, it works fine, but takes over an hour for 300K records. I am using FME Desktop 2022.1Any ideas ?

Access parameter from PythonCaller in Custom Transformer

I'm trying to create a custom transformer 'FeatureCountLogger' which logs the number of features inputted into this transformer. The custom transformer contains a PythonCaller with the following code: import fmeobjects class FeatureProcessor(object): def __init__(self): self.featureList = [] def input(self,feature): self.featureList.append(feature) def close(self): logger = open(FME_MacroValues['Summarylog'], "a") message = FME_MacroValues['Message'] + str(len(self.featureList)) + '\\n' logger.write (message) logger.close() I want to use the logger multiple times, so I created a published parameter 'Message' in the custom transformer, so I can submit the text logged to each instance of the transformer. When I'm running this I get the following error: Python Exception <KeyError>: 'Message' It seems like the PythonCaller can't a

FME Workbench 2022.2.1 failing to install some packages from FME Hub

Hi FME Community,Has anyone run into this odd issue? FME Workbench 2022.2.1 (FME Python 3.10+).I did have issues installing transformers from FME Hub within FME Workbench, though it now seems to have resolved itself. (Note: removed sensitive but otherwise inconsequential information)Initially FME would throw an error similar to: An error occurred while installing Python package with 'pip install --force-reinstall --no-deps --no-index --find-links C:\Users\<user>\AppData\Roaming\Safe Software\FME\Packages\22776-win64\PackageFiles\safe.emailer\python --target C:\Users\<user>\AppData\Roaming\Safe Software\FME\Packages\22776-win64\python\safe.emailer --upgrade --no-compile fme-emailer' : Process crashed.

How to extract from a Lidar point cloud the local maximum Z and its X and Y coordinates for each building footprint ?

Hi,I am a beginner on FME and I have some difficulties.I would like to extract from my LiDAR point cloud, the local maximum elevation with the x and y coordinates of each building footprint.I have as input :- a LiDAR point cloud- the footprint of each building in format shp.As output, I would like to have a .txt file with the maximum z of each point as well as the x and y coordinates of the maximum, all in the same .txt file.I was able to extract the LiDAR points for each building footprint using the Clipper tool.Then I used the PointCloudStatisticsCalculator tool.I get my zmax for each building as a table. But I can't get them together in one .txt file with x and y coordinates.Would you have an idea to solve my problem?Thanks in advance.

Integration of WFS 3.0 (OGC API) Reader with query in FeatureReader fails

FME 2021.2.3.0 (20220131 - Build 21812 - WIN64) I want to query an OGC API feature service by an attribute, to be precise, by a list of attributes.In my case, I‘m trying to query the cadastral parcel service of North Rhine-Westphalia by cadastral parcel numbers: https://ogc-api.nrw.de/lika OGC API - Features (WFS 3.0) Reader:Defining the parcel number as static parameter value works fine.Injecting the parcel number as published parameter works as well.But the 2 ways above are static. I have a list of cadastral parcel numbers to be processed.Normally the FeatureReader transformer is the method of choice to inject attributes into a reader.But this time, it fails!Obviously the FeatureReader doesn’t compose the query the right way and sends a bulk request to the service: https://ogc-api.nrw.de/lika/v1/collections/nutzung_flurstueck/items?f=json&offset=80What’s going wrong?

However, the workbench is still running and I have to manually click the Stop button. Any thoughts?
