Writing Geometries to an Attribute in MongoDB3

I have a complicated collection of features stored in mongo db, where a given feature may have multiple unique geometries stored as individual arrays. I would like to use the “Put” Operation in the writer to replace specific features. However when I write to mongo I get two different results (see screenshots of dummy feature with just one example geometry).location.coordinates{} attribute type set to stringlocation.coordinates{} attribute type set to doubleThe desired outcome would look like this:Referencing other community posts on related matters:After reviewing those other community posts I think I am going to need an alternative method to what I had started to develop. But I wanted to see if anyone had any ideas or experience with mongo writers to say otherwise.Thanks

PointOnPointOverlayer stores duplicates in list, how to read from Pythoncaller?

Problem in short:I have a lot of points which some has identical coordinates. PointOnPointOverlayer does this for me and store the “twins” in a list name. Now I want to use a Pythoncaller to loop through the list of each feature and figure out if some or none of the twin attributes has a value that should update the the major feature. The problem is that I cant seem to reach the list variable created in PointOnPointOverlayer from the Pythoncaller. It seems to be exposed when running with feature cache and checking output from PointOnPointOverlayer. What’s the magic for reading the list, looping throug it and check the attribute values? Tried this example code from the PythonCaller just to see if I could reach the list but can’t see anything:

Visibility analysis with DEM

I would like to perform a visbility analysis as I’m used to with the esri’s fonction arcpy.sa.Visibility.I tried to build something and after goglling, I read this excellent post which is not working for me because I’m currently bound with FME 2021.2 and the script of this post uses a newer version.Is there a way to perform a visbility analysis with FME 2021?Currently it looks like the clipper is not able to work on TIN surface.Any ideas?

Reading coordinate system properties from a DGN file

Hi,We have an assignment where we are using FME Form 2024 version to convert a DGN file to a GIS format. For us to do it, the design file (DGN) needs to be reprojected and scaled to Web Mercator coordinates. I am not a designer, but a developer and learning about the DGN files as I go. The designers using Bentley’s Micro station tool.Using MicroStation V8 reader, reads the “Name” associated with the coordinate system, which is a free form field and can contain a name that the project designer puts in manually and is not a standard naming conversion.We are trying to read more information from the properties of the coordinate systems like the “Description”, “Affine parameters”. The description field contains standardized naming that we could use since it is not editable by the project designer. The Affine parameters define the scale factor that will be used to convert from ground to grid coordinates.Need help in identifying how this can be read through the MicroStation reader or any oth

Parse JSON from Bentley OpenGround

I would like to be able to parse a response from the Bentley OpenGround REST API, and am getting somewhere but not far enough!I can use a mixture of attribute exposer and JSONFragmenter to get some information out, but it never quite looks like the table i want. i will be doing multiple queries over the coming months into this api, and will have a different number of columns each time, so cant parse through each data record based on the number of columns i want in that particular query! I can get to the point where i have a feature for every feature in the database, and then i have a _response_body which i need to parse further. i can keep parsing it through jsonfragmenter, and i end up with a jumbled mess where columns are names wrong and the colunn information i want is in the wrong part of the table. it is a simple structure, such as “DataFields” “heade” for column name and “value” for data itself. i will add some screenshots to aid in query. any help would be greatly appreciated!Th

Aggregator removing projections?

Hello everyone,I am trying to write data into an SQL Database which contains multiple geometries (This is borehole location data containing the originaly measured location (point), a corrected location (point) an a borehole path (linestring)). After creating the geometries from fields and using a GeometryPropertySetter for each of these geometries I am using an Aggregator followed by a MultipleGeometrySetter-Transformer. This is working more or less as in 3 Geometries are in fact written into the database which then also contains 3 fields with SQL geometries as set by the 3 GeometryPropertySetters. But there seems to be a problem. Between setting the individual geometries and aggregation, all info on the previously set projections seems to be lost. Upon inspecting each individual GeometryPropertySetter all points are where they should be. Inspecting the following aggregator shows all points off bounds somewhere. It is my understanding that the aggregator should simply collect the input

ChangeDetector on line geometry, nothing come up as Updated despite UID present i both Original and Revised dataset

I am trying to find line geometry that has been changed between two dataset. I know there are minor and major changes (Tolerance set to 0 at the moment). But the result does not make sense to me. Nothing comes out the Updated channel. Just Intersted and Deleted. Does the Change detection transformer work on lines?All the Deleted features come from Original stream. All Reviced come as Inserted.Is it something to do with datatypes?I just did a test and took a feature from the Delete stream and it does exist in both original and reviced dataset.I am matching on a UUID key example: A53B8017-9987-4636-B941-737AF58C5F08 EDIT: Since I am matching on UUID i was not sure FME handel them as strings. But I did a AttributeValidation on Type String and that came out possitive. EDIT: This is the WKT of the objekt with same id, from two different sources.The result is going to Deleted. But as you can see the WKT is identical. Just to be clear: I created a WKT attribute to double check what was happen

Importing database connections in FME on Linux, no gui

One of my clients is using FME on Linux with only the command line interface and is having some trouble importing database connections. Specifically: they don’t know how to do it on the command line.I can’t find much in the way of documentation for this. I suspect that if it is at all possible it may be through the APPLY_SETTINGS command, but other than that I can see that that exists, I can’t find any indication anywhere on what those settings may be and how to set them.Any clues? Anybody with an old manual somewhere? I do have old installation cd’s and dvd’s going back to FME 2005, but I don’t think I have a computer with a cd or dvd drive anymore 😅 Hoping one of the other long-time users has something stashed away...

How do I write to csv file, naming the file using the value of the first row?

How do I write a csv file and name it using the value in the top / first row?I want just one file to be created, (not multiple files like fanout creates) named after the entry in the first row.For example in the table here I have 9 rows and 2 columns. I want to create a csv of all of this data but named “20231207.csv” As a secondary question, you will see the first attribute column is sorted into date order. If this wasn’t sorted into order, what is the quickest way of identifying the closest date to the current date, and then using that identified value to name the csv file?Hopefully this is something really simple!Thanks in advance.Stu

WKB not becoming a Geometry

Hello yet again 😅I’m GET-calling a an online database through HTTPCaller which responds with giving me a feature in WKB code (in _response_body), then I run the respective code through GeometryReplacer and tried different WKB Encodings in attempts to get a geometry out of it (this should be a polygon), but no luck.The following encodings give me this:Hex Encoded FME Binary: Rejected (INVALID_PARAMETER_GEOMETRY_SOURCE) OGC Well Known Binary: Rejected (INVALID_PARAMETER_GEOMETRY_SOURCE) Hex Encoded OGC Well Known Binary: Ends up in Output and thus not in the rejected port but it does not create any geometry feature that can be inspected.The code is following, so if anyone has seen this before or is enthusiastic to figure this out with me then feel free to investigate:0010300002084080000010000000E000000931E86C64699244192E9D0891B741D41DBF97EF242992441C3F0110102741D41F4A963551A99244180F3E2341E741D41F4531C970F9924415EBBB401E0731D41AED4B380CF982441BF9A03840B741D41001E5119CB982441BB0A294FED73

Reading DWG with 2 transformers

At this moment I received a DWG drawing with both Extended and Object data. To convert this data I first have to read with:Autodesk AutoCAD Civil 3Dthen read withAutodesk AutoCAD Map 3D Object Dataand merge all features on the autocad_entity_handle Am I doing something wrong or is this the only way to get both attributes?Is it possible build a transformer that uses both reading engines because I think that would make the reader faster than current.

Translating attributes from a system of record into feature class in geodatabase

Hi folks,I had a question regarding creating an FME script that takes attributes from a system of record dataset into an existing record created in a feature class within an Enterprise Geodatabase.Workflow consists of the following:Two layers with the same information and attributes in different systems of record – one in an asset management system and feature class in an Enterprise Geodatabase.No integration exists between the two systems yet as there is a new replacement system being developed in a project, but in the intermediary, it has been decided that the business will be updating the asset in the asset management system, then updating the feature class attribute table in the Enterprise Geodatabase. Therefore, they will be maintaining two datasets in tandem until the pilot project for the replacement system is complete.The difference is that the layer in the asset management system only stores XY/Lat/Long values whereas the true layer in the feature class in the Enterprise Geoda

DEM Raster Feature class to JPEG

I have gathered I need to set up bands differently but I have tried the rasterbandinterpretationcoercer and rasterbandadder and rasterinterpretationcoecer in various configurations/settings and can’t seem to get it to write a JPEG. Usual error is about the number or type of bands depending on how I set the coercers etc.DEM raster feature information Any suggestions would be welcome.Thank you so much,Corey

Resolve Domains Function Replication of FCs in EGDB

This replication script would be scheduled in FME Server to run on a nightly basis.The issue is that the feature classes I plan on replicating have several domains and subtypes applied to them that don’t translate correctly.I’ve been advised to use the ‘Resolve Domains’ functionality and change the configuration from ‘coded domain’ type to ‘char’.My test workflow involves the below:Copying the feature class via the ‘Import Feature Class’ tool in ArcGIS Pro into the target Enterprise Geodatabase to have the feature class available in both geodatabases With FME:Selecting the ‘Resolve Domains’ checkbox in the Writer at the outset, and using the ‘Insert’ and ‘Truncate Existing’In the Writer configuration, changing the ‘coded domain’ type to ‘char’ and
