Transformers

Hi, I want to check my dataset( with different layers), which contains polygon and line features for correctness. Which Method can I use to check if there are Layers filled with the wrong features? To check it manually is no option, because the dataset is to large.

I have a bunch of rasterfiles (Geotiff's) which shows flooding-depths under different scenarios. All in all I have 35 rasterfiles with a resolution of 0.4x0.4 which equals ~12 GB each. I also have the same data split in smaller files (approx. 700 files). What I'd like is some advise on how to optimize my workflow. eg. how do i choose a reasonable tile size? Does the float to intergerconversion pay off? Is it faster to call an external rastertopolygon coercer?Right now I: Tile input -> remove redundant tiles -> convert to integer representation -> reclassify tiles -> rasterToPolygon -> simplify -> clip -> collect. Unfortunately the client is reluctant towards resampling the input.  I added a workspace and some exampledata at https://drive.google.com/drive/folders/1AHXnj8nDOZwjqDsam9KCBgMYoKQzAc6i?usp=sharingLet me know if you need more input. Best, Mathias. 

Hey community! How can i create a vector outline from the edge of a raster?

Hello, I have a line feature with a unique ID field. I would like to separate them base on the unique ID, so a feature for every different ID. Is there a way to do it automatically and not do it manualy with a testfilter. Is there a transformer that create feature base on every unique entry in a field?

Hey community! How can I extrude or lay a raster on a TIN surface? With a DEM? How?

I've created straight line segments using the VertexCreator (x2) and Rotator. I need to add an arrowhead on each line segment to show the direction (from vertex 1 to vertex 2). I tried to copy the approach listed here:  https://community.safe.com/s/question/0D54Q000080hg35/convert-line-to-an-arraw?t=1611682329612 but I'm not getting an arrowhead as a result. There is mention of 2DPointAdder but I don't see 2DPointAdder as a Transform. Also I don;t understand the Line and ArrowHead portion of the solution on the link. My approach so far is:What am I missing?

Hello, What are possibilities and what would you suggest to optimize and have the best performance (time response) with spatial anaysis (SpatialFilter and/or neightbor(pair)finder) research ? I work with an "Oracle Spatial DataBase" and at this time FME 2019.2 For exemple if I have a located punctual object with coordinates and need to find the closest street axis or all street axis in a buffer around this coordinates, but i don't want to read all my linear objects "street axis" in the database , otherwise each individual research will be quite slow and I need a high performance for time response Thanks in advance for your help and suggestion Regards Frederic

Hello all,I've got a spreadsheet with filenames, and have been asked to rename the files in a folder/subfolders - with the filenames in the spreadsheet. After joining them, which works fine, I then put it through an Attribute Manager to have the attached image as an output destination (Folders and a Document at the end). I was wondering if anyone could shed any light on why the output files, from the FileCopy writer (both Copy and Move mode) come out as folders, and not the PDF files as they went in?

Hi!  My knowledge of FME is very limited and I'm only familiar with the program. I have several folders containing thosands of .jpgs. I want to rename adding a prefix. I've seen other threads like this but they don't help me at all since I know nothing of the program. This one [https://knowledge.safe.com/questions/41624/is-there-a-quick-way-to-rename-files.html] for example uses a tool named filecopy but I can't get it too work. Any suggestions?

How could i save the output in inspector automatically in pdf file ,i do not want to click on save Data as and choose the type of file Pdf manuel for every time.is there a method to save it automatically ? and also i want to write some legend (as red : way ) at the left down corner for the output in inspector,How could i achieve that ? Thanks for help

Hi,  I am using a matcher to compare 2 schemas (2 esri gdb, original and modified one). Result of this match should be a file which lists new attributes (probably a csv). Can you please give me a hint, how to realize this? Do I need more transformers than matcher or do I only have to configure the CSV writer correctly? (I am using FME 2013 and a FME beginner) Thanks in advance, Christin

Hi All, I want to filter my datasets for features which are closed polygons with surface area>0. I assume I need a filter but which one and how to set it right?  TY

Hi, I want to identify lines in my data, that have the same x and y coordinates and differ only in the z values. Can someone help me out? I'm new in FME.  Thanks in advance Tom

I have two polygon shapefiles that I need to spatially join. I'm trying to populate township/range/section in my dataset based on a TRS shapefile. I have it working in ModelBuilder through ArcGIS but I can't get it to correlate the same in FME Desktop.

Hi. I have a terrain model (in a ESri FGDB) and i want create contour ( interval 1m )from the terrain. Whats is the transformer and parameter that i have to use. Thank you

Hello folks, I have some data of building polygons and some other of court yard polygons, now I want to be secure that there are no court yard boundarys outside of the building boundarys. Is there anyone who can suggest me a Transformer to detect the misplaced court yards? Thank you.

Hi,I am trying to extract a table that is embedded wthin a webpage that is an endpoint. Now I can get the table via html extractor as a lump of html but what I want to do is write it out data as an excel table.One option is to write it out as a html file and then use a html Table reader but I would like to cut out the step of writing out and writing in.In essence I would like to handle the attribute that is a snippit of html that represents the table data I want to manipulate. Would the approach outlined in this post: attributes-from-kml-tag @deanatsafe​ apply? However I think I am missing something as I cannot get the last step to work.Attached is workspace and sample html data.Regards Justin. url example: https://www.nratrafficdata.ie/c2/tfdaysreport.asp?sgid=ZvyVmXU8jBt9PJE$c7UXt6&spid=NRA_000000001803&reportdate=2021-01-01&enddate=2021-01-08&dir=-1&dim1bin=7  

Hello, I want to detect errors in my dataset which contains building areas. I want to be secure, that there is no other outer boundary of a building inside an outer boundary except if theres an inner boundary between the to features, like the case if theres another building inside the court yard of building 1. I added a drawing of the case. Which transformer can I use? And how to set it right. I glad for any help :) Thank you.    

The lines may cross themselves and the ends of the different parts may not be a common point.

 Good Evening, there is an issue I cant solve by myself, maybe someone can help me. I have a dataset of features ,which i want to analyse and one rule is, they need have 3D coordinates and cant be 2D if they dont they should be filtered out. How can I approach this? THX to all.  

HI,Ik have a Civil 3D file and have been asked to transform it into a DEM raster: a raster file with heights as its values. The output format should be GeoTIFF. I've managed to get something out of it but I'm not sure if I did it right.The input looks like My workspace is this one:So I converted my surface into 3D points and then with the RasterDEMGenerator into a raster. Is this the only and best way to do this? Thanks,Arno 

 I have opened the GEOTIFF file in Data Inspector (see screen capture below) and I do see the mapping attribute, containing a list with all the values.So, I somehow 1) need to read out these values from the mapping attibute and 2) replace the band values with the textual value. Sure FME can do this, but I did not yet figure out how... 😃 Any help will be appriciated. TIA, Egge-Jan

Hi,I'm new in BIM and IFC. I have two problems with import IFC file. I used Industry Foundation Class STEP/XML Files (IFC) Reader and I got a messages: The first problem:,,A 2D feature was encountered in the feature class 'IfcWall_line', which is defined as containing 3D features. The feature, and any other applicable features in the same feature class, will be modified so that it has the same dimension as the feature class" What does it mean exactly? Is it a problem with wrong geometry?  The second problem:,,Error encountered while copying traits to generated solids. Some solid components may be missing traits, appearances, measures or attributesProcessing on a solid has failed. The solid may be too complex, not closed, or not orientable.Processing on a solid has failed.

I'm building an html file with data and charts. The PNG charts generated with the ChartGenerator transformer have huge white borders around the actual chart and legend and make my html look bad. I want to trim those borders and I'm doing this, but I wonder if it's the best approach:I use a RasterBandNodataSetter to set white colour to Nodata value. With RasterExtentsCoercer adjusted to use DataMBRExtents I get a polygon with the extent without the white bordersAnd with the Clipper I clip the PNG chart with that extent. I there any other way of doing this? I have 16 charts to add to the html file so I'd prefer to do this same thing with just one or two transformers. 

Is it possible to use the ChartGenerator output chart without writing it to a PNG file first?In my workspace I'm generating a few charts and I need to use them along with other data in the same workspace to output an html, an excel and a pdf ​files.For example, you need to do something like this to generate an html file with images. I would have to save charts as temp PNG files to read them again in the same workspace and use some extra transformers to get the PNG as an attribute. Isn't there an easier approach?​​
