Transformers

Hi!  I would need to prepare a FME-based flow doing more or less what the "Erase" tool of ArcGIS is doing. As there is no equivalent transformer (correct me if I am wrong), I use a Clipper transformer as shown in the attached workspace. How could the process I came up with be run in an acceptable amount of time (close to the 25 minutes of ArcGIS Erase tool) while preserving the attributes of the layer being erased (which ArcGIS does by default)? Indeed for many projects we need to recuperate a lot of information from those specific roads in order to create them with all the required attributes. Preserving these attributes in the process will have a significant impact on performance (I stopped the process when it was already running more than an 1 hour). Even preserving only the Id and then using later on a FeatureMerger in order to join the original attributes to the remaining roads (after clipping) results in a lengthy processing time (1 hour 19 minutes

Selected blue area is polygon. Red lines is line.I want to cut the blue area according to the lines and create 3 areas.  

The workspace tries to read a CSV from internet and write a feature class in a geodatabase. I am trying to use this workbench with a remote desktop machine, which has all the licenses needed installed. Just a note, the workspace works perfectly well in local when not using the remote machine.  It also works when using Open API geodatabase writer or shapefile writer. I though it may be a licensing issue, but then the workspace works when you run it from the beginning to the join and then from the join to the end, instead of running the entire workspace. So I though maybe it was the temporary storage failing, so I changed the temporary files storage folder but the same error appears. BTW, the error is very generic "Error running translation" so I do not know what else to do. I would appreciate any help to solve this issue. Right now I've split the worspace in two, one to read and download the CSV file in the remote

Is it possible to set up the spatialRelator, or other transformer, to identify a relationship where the features touch along an edge rather than at a point. I know I can set the spatialRelator to Calculate the Cardinality of Intersections, and then filter the _relationships{} list to remove any elements where _relationships{}.card_line = 0, but that is non-trivial (ie python), and then recalculate the _related_suppliers attribute, but I'm hoping there is a less involved option.

I often use GDAL Warp to minimum sample rasters. I struggle to perform such a resampling in FME and it ends up involving a lot of operations and/or external tools.  Does anyone have a tip?

I have a very large conditional I would like to export to text, so far I've tried copy/paste, and can't seem to find any other ways. However it doesn't wok.

Hi; I installed the FME Plug-in SDK for C ++. When compiling the sample solution, 2 files are missing. "fmeplugincapabilities.h" and "ipipe.h". Where are these files located?

Hi, is there a way to find the last OBJECTID in an ESRI FileGeoDatabase and return it? I can do this using SQLCreator > VariableSetter > VariableRetriever > Counter transformers for an Oracle Spatial Database but a FileGeoDatabase is not listed in the Reader Gallery within SQLCreator transformer. My knowledge of FME is pretty basic and would appreciate a 'how to' (if it's possible). Thank you

How to create a Polyline shapefile from CSV/excel data

I would like to know what would be the simplest step to transform the following source:  to the following  

Thank for the support

I have an Excel Reader and several transformers that follow. I would like the attributes to update when I select a new .xlsx file. Most attributes should be the same but on occasion a file is submitted with one of the column names a little bit different. I was hoping that I would just have to re-connect those. What I have been experiencing is that I have to Update the Reader and then my AttributeManager transformers have to be completely rebuilt. Example:First Run - Fieldnames are CITY, STATE, ZIPSecond Run - Fieldnames are MY CITY, STATE, ZIPCODE Is there an easy way to handle this?

I have been tasked with reviewing another person's FME workbench, which contains a Python start-up script. When I try and run this script (from a PythonCaller transformer) I am receiving the following error i.e. Python Exception <ModuleNotFoundError>: No module named 'fmeutilities' andERROR |Error executing string `#global scope variable definitions / initialisations. The script is trying to import the modules 'fmeutilities' and 'fmeoutput' amongst others, which cannot be found on the server that the workbench is running on. I'm not sure if these need to be added via a localised install of Python or not? I can find an fmeobjects module on my server i.e. in the C:\\Program Files\\FME\\fmeobjects\\python37 folder) but non of the other modules the script is trying to import. I am using FME Desktop v2021.1 and the workspace python compatibility setting is set to Python 2.7 and 3 (see att

I've played around in Python in an ArcGIS Pro Notebook and like to take that code into FME. Because of organizational reasons, I might not be able to import the modules I need. Is there a way to make the profiles with other transformers? or some other way in Python, maybe?Attached is the code I use in ArcGIS and the testdata used there. Further attached is an example of the profile.  The data is organized in drill cores consisting of multiple layers, the thickness is indicated with Laagdikte [mm], the sample data has 3 drill core with 6 layers each.  Any kind of help would be greatly appreciated! Thanks! Linda

I want this feature set to be processed per tracknumber. So first all the features with tracknumer 1 (2 features), then with tracknumer 2 (3 features), then trackunmer 3 (2 features).From each subset only one feature has to be selected, based on 2 rulesif all features have 'yes' in their decision attributes, select the one with the most recent dateif one of the features in the subset has a 'no' in one of the decision attributes, select (one of) the no fields, doesn't matter which one.The resulting featureset is seen in knipsel1.png I have tested a Matcher , but then I am stuck more or less. I put the subsets in a list in the Singlematch output port. If I use a Listexploder, I get all the features back in one set. I want to take each feature of the singlematch output port and process the Listelements in a seperate process (in a workspacerunner), but how do I feed one feature (with a list) to the workspacerunn

How can I convert a sketchup lod4 building model in cityGML format

This seems like a pretty basic question to ask but something we haven't encountered yet with FME Desktop. If we have two datasets and I only want to do a one way synchronization of the attribute values from a new polygon layer to an old polygon layer. How do I do that? I don't want to overwrite the geometry features in the old layer, but I do want to "calculate" the new attribute values over to the new layer. Will just changing the geometry in the writer dialog box from polygon to no_geom and selecting "UPDATE" as writer mode do the trick? It doesn't seem like it would be that simple.

The photo's has a border. I plan to crop these out after the scanning procedure. Any idea how to get this job done ?

Hello, I'm new to FME and want to work out which transformers can be used for this task. I need to query a text field held in a CSV file against a list of values (text) stored in a separate CSV. If these values are present I would like to add a value of '1' to a new field in the CSV. I'm sure this is very basic but would be grateful for any assistance!Chris

I am creating PDF documents with a series of responses, so I first create a multi-line attribute then I pass that through the PDFPageFormatter and onto a PDF writer. The problem is some of the responses run off the page. I am needing to restrict the width of the multi-line attribute using something like a word-wrap function. Any ideas?

I have a *DWG file. I want to convert it to GeoTIFF. I used tool from link: https://hub.safe.com/publishers/safe-lab/templates/converting-vector-data-to-raster#description. Even though it exports successfully, I don't see the GeoTIFF output.What step am I doing wrong?Please tell me. Thanks

I'm trying to use snapper to snap a line and an arc together using their end points, then a line combiner to combine them into 1 straight line. however it doesn't appear to be working. I can cheat and use a straight line instead, but I'd like to know the correct way of doing this, as I'd like to keep the data as accurate as possible. Also, if the door comes out as *untouched* in the snapper, the rest of the process works, however if it snaps to form the half semicircle then the co-ordinate extractor and vertex creator fail to create a line. Can anybody explain this to me?

I've created a new Output Attribute in AttributeManager and I want to populate this based on the results of a (rather lengthy) SQL query. However, the SQL will be looking at attribute values from the reader and not a database, which I think rules out SQLCreator and SQLExecutor.Does anybody have any suggestions as to how I might manage this?

Hi Guys, I have two feature classes in SDE and I want to append featureclass A to featureclass B and do a few additional its like dropping and recreating indexes and setting a value on newly appended data.I have this working but very very slowly, so i assume I have taken the wrong approach. ?I have an ESRI SDE r eader, connected to the fetaureclass A, and sets max features to read per feature type 3000000, I have Sql to run before read- which sets an attribute with date and time of now so I can track the records later.I then use coordinate setter and attribut manager and connect to a ESRI SDE writer, I have set this on Transact mode with 0 Transaction Number and 100000 Transaction and Features Per Transaction to be 100000 and Commit at end of Write to be NO . I drop indexes in Sql Before write and recreate them afer write .. potentially f
