Exploring non spatial relationships in a large postgres datatset

I have a large postgres database with over 100 layers. I would like to know how, and if, the indvidual layers relate by a shared attribute. For instance: a river will have an attribute with the county-name it flows through. However, the county will not have an attribute with the river name (but wil have an attribute with it own name). Both will have a completely different geometry obvioulsy. I am also not interested in creating that attribute (using spatial relator). I just want to know which features share which attributes. Since the dataset is so large I can not use the matcher since I will not know beforehand which attribute might match. How would I best go ahead to try and find these relations?

FME Desktop 2020.2 installing scipy library, numpy version error

Hiwindows 10, FME desktop 2020.2.5 I installed scipy using pip"fme.exe python -m pip install numpy --target C:\\Users\\<user>\\Documents\\FME\\Plugins\\Python\\python37 " I check numpy version and it says 1.16.5 using pip list in commando prompt. But when I run the script in FME desktop it saysERROR |C:\\Users\\<my username here>\\AppData\\Roaming\\Python\\Python37\\site-packages\\scipy\\__init__.py:149: UserWarning: A NumPy version >=1.16.5 and <1.23.0 is required for this version of SciPy (detected version 1.15.1 UserWarning) But the only version of numpy that i have installed is 1.16.5. Any suggestions on how I can fix this problem?

Is there a Swagger/OpenAPI for the REST API?

We'd like to publish the /fmerest/v3/ API in an API Manager.It's well documented and structured here:https://docs.safe.com/fme/html/FME_REST/apidoc/v3/index.html#I was wondering if there's also a OpenAPI definition of the services.

I have a file in format of .e57, it contains point cloud and raster.I plan to firstly reduce the number of points and export again as e57 that also contians raster and point clouds.After processing the point cloud data is there 2 options in transform Writer: Raster, Point cloud. Which one should i choose? Or can i just export the raster and point cloud separately(like the picture below), and then open these 2 data file in FME Inspector at the same time and save as format .e57?Thanks in advance.

Question for "HTML" writer output file naming

Hello everyone, So I have a workspace, at the end I will output the HTML result by using HTML transformer. For my html report, I would like to have my writer naming: input file name + _level For instance, if the input file is: abc.geojson, the output file is: abc_level.html I tried as the figure below, yet it is not working. Could someone please give me guide on how to make it works. Thank you and sorry for soooooooo many questions recently. Zach

Double field type interpreted as int type - FME 2021

Hello, I noticed something weird with my reader.The primary key from a Geodatabase_SDE table is interpreted as int type on my 2021 version but is correctly interpreted as a double type on my 2019 version. Reader's properties on 2021 version :Reader's properties on 2019 version :Allowing reader feature type editing won't change a thing. All the id values are set to 0 through the inspector.Also, double fields type from the same dataset are well interpreted. Both versions. Thanks for having a look.Regards.

How to do a post-request with httpcaller, filling the body by data from a transformer without sending the data within the post?

Hi, I try to request data from an api by a POST-request with httpcaller. Every post works fine when I set the parameter geodata in the body manually like this:{"geodata": ["FCA","FF"],..."}These are identifiers of features, which I want insert dynamically by an other transformer (Attributekeeper). The attributekeeper delivers one field called BSTs with this content: "MLLF","DPU","WWM" {"geodata": [@Value(BSTs)],..."} As soon as I activate the connection between attributekeeper and httpcaller, the api sends a "403" not allowed. I suppose, that the httpcaller sends the data of the transformer attributekeeper within the POST, what is not allowed by the api. But strange is, that I send allready the authentification-token to the httpcaller to use it in the header. This works... Any ideas are welcome ;-)Best regards, Christoph

What's Up Wednesday (23-Feb-2022): The EsriReprojector, Python Training, Women in Tech, Pink Shirts, and another Fireside Chat

Welcome to What's Up Wednesday, your weekly FME news roundup. EsriReprojectorAnyone who tuned into the sneak peek broadcast yesterday was treated to an in-depth look at the EsriReprojector transformer and what has changed in 2022. The two main upgrades are time-based coordinate reprojection and vertical datums. The time element is controlled by the coordinate systems selected and the Epoch parameter. A separate set of parameters control the Vertical Datums. And, yes, I asked and you can do both at once! That's the final sneak peek I had planned. But I've got used to streaming with guests on a Tuesday afternoon, so, I'll try and line up more presentations, whether they be sneak peeks or something else, to keep us both educated and entertained. Women in TechOn the agenda for March is a webinar titled Empowering Women in Tech. It's not about FME, per se, but about the women who work at Safe and how their careers progressed. If that's of interest to you, we hav

Good Evening, Firstly, I'm not sure if this is the correct place to ask this, or if there is a private message function that I haven't found. But I am looking to use FME to automate stream delineation via LiDAR derived raster analysis. I noticed your comment under this forum post (https://community.safe.com/s/question/0D54Q000080haNDSAY/generates-drainage-networks?t=1645628766878). I have downloaded your workflow and taken a look at some of the processes and was wondering if FME has had any updates to further the scope of my goal. Or if you have came across any new/better processes yourself since posting your suggestion. Once again, if this is not the proper place to leave this comment, I apologize. Please reach out at your earliest convenience.

Cesium 3D Tiles (b3dm) Conversion from Raster Elevation/Imagery

I only see that a couple of specific workflows are listed for conversion to 3D Tiles - these include Wavefront OBJ, CityGML, geojson, shp, and FGDB...We would like to simply input raster imagery and elevation (geotiff for instance) and output 3D Tiles.An example workflow that would be acceptable if supported:Raster geotiff imagery to TMSRaster geotiff elevation to TBD FME Mesh format most optimized for conversion to 3D TilesTMS Imagery and FME Mesh to 3D Tiles (b3dm format)

FME Server REST API Return File Extensions for File Upload

I've built a python fastapi web application using the FME Server REST API and was wondering if I'm overlooking where the file extension filters are returned for any file parameters. While I see all of the other parameter information, I am not seeing the file extensions specified in the workspace for a parameter. It does not show this in the REST API call for /repositories/< repository >/items/< item >/parameters, so I was wondering if it is somewhere else or not available at all. Is this a limitation to the FME Server REST API perhaps? The reason for this is that my application is fully dynamic, so the FME workspace drives the creation of the form inputs.

Hi, Is the following possible?An FME workspace writes to a table. After the writers are ready I want that process to continue with other transformers and an other writer which must be writing last. I don't want to create 2 workspaces.

FME Desktop 2022: What is the equivalent tool for ArcGIS “join field” in FME?

FME Desktop 2022: What is the equivalent tool for ArcGIS “join field” in FME? I couldn’t figure out if there is a tool that’s equivalent tool for ArcGIS “join field” in FME. For example, in the screenshot below, I wanted to join the attribute table of the layer L1 with the table T1 to end up with having all the fields of table T1 in the layer L1

using stringreplace with files name with comma

I've found this documentation that mentions that comma should be surrounded with quotes when using in string functions. But the case now that I receive a file name (which contain comma) in a published parameter, then I want to replace part of the file path with some other string using "StringReplacer" function. I can't do this as the value retrieved in the published parameter has already the comma. Any Advise?

Fanout output directory setup

HelloI 'm trying to have the Fanout output directory stamped by date, I successfully did that except FME creates 2 folders of same content except one with the date stamp and the other without. Both directories are identical from inside, any advice?I'm using the parquet writer to export Revit elements properties to parquet files, here is my settings for output directory.The output comes as following:What I was expecting is the folder with date only???The same other folder "rst_basic_sample_project" with all its content is replicated in "2022-02-17"I only want "2022-02-17"

Extracting Top Surface from 3D Solids

I'm trying to extract a tin surface from 3D solid mesh in an FBX file.Ideally we would extract the top and bottom as separate surfaces.Any Ideas?If it isn't possible to filter the top/bottom triangles to create a surface, is there a workflow to create a raster grid sampling the highest/smallest Z at each point?
