FME Form

I have a following problem: I want to group and build lines from points based on two different groupings. Firstly by category_id that indicates certain categories for the lines (number of categories varies from 1-7). Secondly by "line_number" that indicates consecutive measurements points (see first picture with four point lines). As a result (see second picture first line) or in another words I want lines where category change starts a new line within "line number"-group. Points have order_id so it is can build the lines in particular order. I've tried LineBuilder but can't figure out which aggregations/groupings I should do and in which order.   

Hi everyone, I have a question about my thesis.I have a point layer witch including data about the traffic(speed, cars number ect..). And I have a road layer. I don’t know how to connect the the point layer to the line as the closest segment of the line get the datas from the closest pont… Thanks in advance

I have a CSV file containing the four values of a bounding box. I would like to read the file into FME and populate the four search envelope values of an SDE reader in order to clip the data to the search envelope when reading the data. How do I populate those four values from the file?Thanks,Aaron

Hi,I am trying to do transformation using Snakegrid projector to OSGB.I have appropriate Snakegrid license as per FME desktop registration key. However, looks like I am facing issue with python compatibility.  I tried some workarounds as below:1.     Installation of FME desktop & Snakegrid projector with the help of expertise in the team2.     Installing FME desktop version (2021.2.1) with customizing python option3.     Setting up python interpreter in Translation (tried using all options given in drop down), But when I try to add Snakegrid projector it used popup with python incompatibility and changed to python 2.7 Error snapshot as below:Please can anyone help me with this issue?

We are producing Cesium 3d Tiles from .dgns, our problem first was that some elements seem to have the wrong surface normals, or so we think and our fix was to use the Orientator transformer, produce a Reversed version of all elements and then Merge these elements back together so we don't have duplicates. What occured afterwards is that some elements have weird shadings that change as you orbit the element, is there any fix to this? Is this still an issue with the surface normals? Or could it be that some inner color bleeds through because of the normals 'fix' we did? Thank you in advance!

Hello, I'm trying to convert .dwg to cesium 3D tiles, but exported 3D tiles seems to have only one-side surface. Any ideas how to export 3d tiles with front and back side? I tried lots of transformers. In FME it seems to have double-sided surface.  Many thanks

Hello, I am trying to create a polygon from different point clouds files. After the reader I use the "NumericRasterizer" and then the "RasterExtentsCoercer" but after the rasterization I receive 1 file as an output instead of 8 that was the input. Which means that they have been merged somehow and therefore I have one polygon. How can I keep the individual files and create an outline per file?

I want to convert 3Dsolids (dwg) to a shape. But the shape is to complex I just want the boundary of the multisurface. How can convert these multisurfaces to a boundary? Thanks

FME is aware of the file extension .nc, but appears to be unrelated to the file type I am using. Please see attached file sample (note the original file name is louves.NC)

Hello FME users, I am looking for a solution that is the equivalent to ArcGIS snap raster. My situation is that I have road netowrk, rivers and lakes (all in vector format) and I need to transform those into raster format. I already have a grid template (coming from a 10m resolution slope raster) and I want all my vector to raster outputs to fit with absolute precision. I have tried to use min/max coordinates but the resultat is not good enough (see images below for transformer parameters and resulting rasters.) I am sure this standard ArcGIS procedure MUST have an equivalent in FME(otherwise, PLEASE make sure to develop one!). Can anyone enlight me? Kind regards,Anne-Marie

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.

(on FME 2020.2) Hi,  I have a workspace with an Oracle reader in which I want to filter the features to read with a WHERE clause on a column, let's say COLUMN_A. I created a Choice type published parameter named colA, which contains the possible values for this column.This way I can filter the features from my table when COLUMN_A contains the value selected in the Choice list. The WHERE clause is : "COLUMN_A" = '$(colA)'Quotes character are used to handle the values with spaces. Problem : the values can contains the quote character as well !What is expected for the database (Oracle) is that the simple quote in the value should be doubled. For exemple the colA value TES'T should be transformed to TES''T. I tried to find a way to replace the simple quotes with two quotes in the WHERE clause using SQL string functions, without success because it always require to have the doubled quote. The only workaround I found for the moment is to change the Choice parameter to a Choice with alias par

   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. 

I have an array of polygons representing a surface triangulation.Because of the source of the data, some faces are vertical which aren't supported in the TIN I'm trying to create.Any ideas on what would be the best way to overcome this? I'm sure its a common issue, be interested to see how others handle it.Maybe convert to lines, filter overlapping lines with different Z values and offset both a small amount?

I’m struggling with the TopologyBuilder transformer and, since I’m sure my use case is quite common, I hope someone might be able to help me. I want to extract the topological boundary polyline from polygons. In addition to the polyline geometry, I’d like to carry polygon attributes through to left and right-side attributes of each new polyline. For example, if my input polygons were countries of the world, I’d like my output polylines to be borders with each attributed with the country on each side. e.g. Left: France, Right: Germany. I’ve got the polylines geometry coming out of the TopologyBuilder perfectly, but not so lucky on the attributes. I get _left_face and _right_face attributes coming out, but these edge IDs don’t seem to mean anything. They don’t relate to any input attributes, nor are the polygon table row id. I’ve also tried “Generate List From Input Faces”, defined a list name, Selected Attributes, and my attribute field name. Sadly, none of these are populated on the ou

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           

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?

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"

is there a way to convert mxd to cad? including all the symbology?

Hi, I have a set of hundreds of shapefiles and another set of hundreds of rasters. I don't want to use ESRIReprojector transformer individually for each reader and writer. What's the most efficient way for batch transforming their CRS in FME?

I have gps points that indicate the speed of a car, I want to sum them around 50 meters averages them. which transformer offers and how it would be worth usingThanks in advance

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?

I am building a vehicle location tracking dataset where I want to keep a history of vehicle locations for future analysis. I am using the ChangeDetector to compare the values in two tables based on a field called [device]. I want to compare the [device] in table 1 with the most recent [device] in table 2 and if there has been a change, 'insert' those values from table 1 into table 2. So where [device] is in table 2 multiple times, I want to compare only the most recent record of the [device] details. When running the ChangeDetector, i have noticed that everything in the Deleted output seems to be the older duplicates. This moves me to my question. Does ChangeDetector just look for the first match for the value and move the others to the Deleted port? Does ChangeDetector use the timestamp field that I have to automatically detect the most recent? Can't seem to find any documentation on this?

Hi guys, I'm trying to set up an html-based application that allows assignment of attributive information. The html page comes out of a Serverapp and is presented to the user by a Data Streaming service. Currently I only manage to create a static page tha visualizes the "as is" situation. Is there a way to turn this page into an interactive mode, that re-establishes communication with FME Server on user request (button click etc.)? Does FME provide technology to fetch user input from text fields, context menues or any other gui object present on the page straight out of the browser?  Looking foward to your answers!
