Transformers

Hi everyone, Apologies if I'm asking in the wrong section, but I've been stumped with a geospatial problem and I have no idea where to even begin solving it.  I'm working on a project where I have a bunch of lines inside of polygonal land parcels. Here's a rough sketch of what I'm talking about: I need to further subdivide these parcels into sections that contain ~80km of line each, while trying to maintain line connectivity as much as possible. So as an example, I'd want the finished subsections to look like this (very rough) sketch here, where the blue line represents the boundary of each subdivided polygon that contains ~80km of line:I've used FME a fair amount, but I have no idea where to even start creating a workflow that can handle this. I know I can use LengthCalculator to get length attributes for each line, but I'm completely clueless on where to go after that. If I can get the lines selected and attributed into discrete groups using length tot

Using the GeometryPropertySetter to set Traits to IFC files needs to use an AttributeExposer to be able to select the right attributes to put on the trait. This does not work well on Dynamic Workspaces with 20-100 attributes. Is there a way to use the GeometryPropertySetter in a dynamic way? For instance submit a list of attribute names or some other "hack" to make this dynamic for "more IFC-files"?

Hello,I'm creating a collection of building models from an ESRI file GDB feature class. I'm writing eachmultipatch to a Wavefront OBJ file. Any number of these OBJ files may be imported into a modeling program at the same time. I've had problems when different models refer to texture files that have the same name.  My workbench assigns a unique name to each OBJ file. I want each texture associated with a model to employ the unique obj name in the name of the texture image: eg: bosYU9732_[n].jpg Currently, FME names each texture "noname[n].jpg where [n] is a small integer.  I found this thread from 2014 which seems to include tips for hacking the .mtl file. https://community.safe.com/s/question/0D54Q000080hE7FSAU/rename-material-and-texture-from-wavefront-obj-to-obj Unfortunately many of the links are broken, and it is not clear whether any of the replies were useful to the original poster. Has anyone got updated tips or an example for me?  Thank you! 

I have a workflow last run about 2 years ago that uses several html extractors to get information form various parts of a website. I went to run it again without changing anything and got the following error `fme_rejection_message' has value `PowerPlants_HTMLExtractor: <class 'soupsieve.util.SelectorSyntaxError'>: Malformed attribute selector at position 0 line 1:[id=Height_of_the_Dam_(m)_nbr_rng1]^'I have other CSS selectors configured the same way that are still working. Any ideas   

I want to convert a file (.las) to format (citygml), but when performing the task in the software (FME QUICK TRASLATOR), it generates an error. the file in (.las), is a file made with drone

Hello ! I have MultiCurve objects (GeoJson MultiLineString) that represent routes along roads, and which have some geometry issues : sometimes lines are overlapping, and some lines meet at a point but with opposite direction.Here is the overall dataset :And here is a problematic area :Exemple dataset is available [here].So my question is : is it possible get a cleaner file, with no overlapping lines or segments, and with a better global direction consistency ? And how to do so ?I tried to use Deaggregator, Intersector, Snapper, LineCombiner; and a few more, but so far I don't fully understand what I am doing, and don't get closer to what I want. Thanks in advance for any tip or help :)

Hi, thank you for reading my question! And maybe you have an idea? Please let me know! It's about: filling the nodata gaps in a raster.So, I have downloaded a DTM raster file. It's based on a pointcloud and some classes are filtered out, like water, building, vegetation, bridges. That leaves some nodata holes in the raster. I like to recalculate them, based on the nearest cell values. In the past, I did this with GIS and some neighbor tools for rasters, but I can't really find how to do this in FME. I have tried the RasterDEMGenerator and also the RasterConvolver, but without any good results... maybe I don't use them well or maybe I should use a completely different approach? No clue anymore. Any help is appreciated! Best,Harmen

Hi there, I have installed the pandas library into my workstation using the following command:fme.exe python -m pip install <package_name> --target <package_destination_folder> and got following message:Successfully installed numpy-1.18.1 pandas-0.25.3 python-dateutil-2.8.1 pytz-2019.3 six-1.14.0 However, when in python Caller I tried to import pandas using the following command:import pandasand ran the transformation, it throws an error message:Python Exception <ModuleNotFoundError>: No module named 'pandas' Could anyone help me in fixing the error? 

Hello! Is it possible to extract coordinate pairs (lat/lon) that are within an actual shapefile boundary as opposed to using a bounding box of a shapefile? When I use the BoundsExtractor transformer I'm getting more points than warranted. Thanks.

I would like to change the table names of my citygml file. How can I realize that? I need it in order to transform my citygml to an imx file. thank you in advance.

I hope the title is already quite self explanatory.To illustrate the issue,I generated some (lowercase) text strings with 10 to 50 characters, using the methodology that was described by cwarren in the topic https://knowledge.safe.com/questions/88643/random-letter-generator.html.I first used a stringsearcher transformer with the pattern '.*?a.*'I then also used the FindRegEx stringfunction in an attributemanager for the same expression, with various combinations for configuring the optional parameterswhile including or excluding "" characters around the regex patternwhile including or excluding the ^ and $ anchors (for 'start of string' and 'end of string')I tried searching for only part of the string in the stringfunctionwhile also trying various combinations of greedy vs nongreedy searches.i.e. '.*?a' is a non greedy search to match 'zero or more' (i.e. '*') of 'any single character' (i.e. '.'), until the first

I have a data set with multiple repeated values such as thisADAADAADABentonCanyonCanyonDearbornDearbornDearbornDearborn and I want to increment a count every time the preceding value is different than the next value.so my 'count' would be like1 - ADA1  ADA1 - ADA2 - Benton3 - Canyon 3 - Canyon4 - Dearborn4 - Dearborn4 - Dearborn4 - Dearborn

Hello - I have a file geodatabase where most feature classes contains an attribute 'text_desc'. I would like to extract all unique values, and concatenate those into a single comma-separated attribute to generate a report. Due to slow gdb read times in FME, I would like to do this in PythonCaller for efficiency. Is this possible?

Hello, Is there a way to change the style of bullet points in a word written with fme? Thanking you in advance

I think bei Problem is to handle the traits and to attach them to the Objects.

I want to trigger a FEATUREREADER to run only if there are records that pass a tester. But I don't want to pass all the records to the FEATUREREADER, only trigger the reader to start. The passed tester records will be used in a different transformer but I also want to trigger the reader to start if there are any records that pass the tester. What is the best way to accomplish this? Thanks, David

I'm having an issue with the FeatureWriter where it writes to a database successfully but the features don't come out of the Output Port which I need to continue the transformation.  Why aren't the features coming out of the Output Port? In the screenshot, 3 records are written to the database but do not come out of the Output Port. Since I'm writing to an ArcSDE database and I can't control the GlobalID, I have to write to the database then re-read the features after the GlobalID have been written.

The counters have to all be on the detailed data. I have tried putting the attributes to group in the counter name but this second counter is restarting each time and I want it to be incremental - as per the attached.Both counters are set to Local and have different counter names.I'm sure its something very simple I am missing but I just cant work it out

How can I expose the raster feature information? Looking to expose the band values.

I have a DWG that I am trying to create a polygon from to represent the extents of the data.The polyline data doesn't seem to be able to be coerced to form a polygon and I am unsure why.I have tried to aggregate the polylines into a single feature, but no luck.

I'm trying to create 3D Buildings (Lod1) from shapefile, I extrude the buildings but I can't see the 3D models in FME (and inspector). While in FZK everything is OK, what am I doing wrong? PS. I use shape file from OSM

Hello,I have an Excel file with WKT format geometry in two separate columns (attributes, correct?) that I am struggling to encode without creating duplicate rows (features) or overwriting one or the other. Using GeometryReplacer, I can replace the geometry separately, but if I chain them together, only the last one is shown as it goes into 3D Coercer. If the GRs are in parallel, they create duplicate rows. It is important to keep the row structure intact.  Above, the Boundaries and Rep. Points transformers are the GeometryReplacers. Obviously, this is no good, but it is the only way I can see both attribute geometries. This what I want (but without the dupes):Ideally, it would be something like this, but it doesn't work:Per the "Go with the Flow" article, if the Workspace takes each feature(row) through the process before moving on, why does GeometryReplacer negate the first GR (Boundaries) and just encode the last (Rep. Points), even though the source attributes are

Hi, I'm using FME to parse a JSON file and eventually upload specific parts to an Oracle table.One concept I'm not sure how to approach is, what to do when the JSON has a nested list, that is always a different size?Would the JSONFragmenter be the best option in this case, or something like the JSONExtractor? When using the JSONFeature reader, I can only get one item of the list at a time. I've attached a snapshot of how the section of the JSON looks. 

I have a workspace that reads from non-SharePoint sources and writes to SharePoint. I am using a change detector along with fme_db_operation to insert, delete, or update accordingly. However, I recently noticed an error message that the updates were not updating and required a sharepoint_item_id.  1) Is there a way to update SharePoint without the sharepoint_item_id, perhaps on a separate unique attribute, or is sharepoint_item_id mandatory? 2) If 1) requires sharepoint_item_id, what is the best way to attach sharepoint_item_id to records. I can imagine a reader, then join, but wondering if there is a best practice for these cases. Thank you, Tyler
