Transformers

I would like to replace the content of one node in XML fragments (SLD/SE), which I import into FME. I merge these fragments to other features with the values for the replacement and want to do the replacement for each feature.With the XMLUpdater that seemed to be an easy task. Nevertheless, using the configuration as shown in the attached workspace, the contents of the node allways gets replaced by the value of the last incoming feature, not the value of the feature with the corresponding XML fragment. I read a lot of articles here in the FME community but could not find out what I am doing wrong. Do I missunderstand the function of the updater?

The tolerance in TINGenerator does not seem to do anything? I have a workspace where a geotiff gets converted to a pointcloud for some processing before running through a TINGenerator. I have tried values between 1 and 1000 but it always outputs the same amount of VertexPoints. Only thing that makes any difference is if I set the value to 0, then the amount of vertexpoints get multiplied by a million. In the same workspace I also use a PointCloudCombiner. Where the value of the point interval does not seem to make any difference. Does the workspace need to be set up in a specific way in order for the above to work? Or have I just missunderstood what the values are supposed to do?

I have a pretty complicated model which has many input data sets, transformers and lots of intermediatary data. I need to write a summary of the statistics at the end of the procedure including total area of results, proportions and ratios taken from the data. Which Transformers could I use to select or create statistical summaries and write them to text?

I have stumbled across a raster size problem in RasterExpressionEvaluator whereas two input rasters are clipped using Clipper to the exact same shape, however some of them upon arriving for raster calculation differ by one pixel.The problem is that although all input rasters are of different sizes only some in several hundred will result in this error quite randomly despite use of clipping that should cut them precisely to same size.|ERROR |RasterExpressionEvaluator_2(RasterEvaluationFactory): Raster A has '2119' rows and '2042' columns, whereas raster B has '2120' rows and '2042' columns. Paired rasters must have the same dimensions

Hello, I have a line file that I need to divide into 5 mile sections. At each 5 mile point, I need to create a perpendicular line off to the left side of the line. I need this line to be certain lengths or be able to divide the line into sections afterwards. I need to then export the coordinates of each vertex along the perpendicular line. Please see my drawing what I'm looking to create. I need the coordinates of each location where there is a home placed on the drawing. Thanks!  

Hello Somehow there seems to be a problem with the WorkspaceRunner and privateParameters in the Workspace, that should be run. .. (I use FMEDesktop 2022.1) I get this error-message:Undefined macro `Pfad_MGDM_Files' dereferenced in file `I:\\AGI\\Geoinformation\\Produkte\\GDI\\Themen\\A021 Laermempfindlichkeitsstufen\\c\\etl\\wb-xlate-1668001125589_14180' > the Parameter `Pfad_MGDM_Files' is a private parameter in the Workspace to be run, and I use it, to concat a filepath. A private parameter should be of no interest to the workspace with the WSRunner...? I attach the workspace below. Thanks in advanceVera

I am using the attribute manager to remove fields from my schema that I am writing into an Esri file geodatabase. I am finding that the fields are still present in the new feature class that is being generated but now have null values.  Is there a way to do this?

Hello, can you help me? I have .las format cloud point as input and I want to get buildings with roofs?

Hi, I wanna test if geometries are within an given area, I found the Spatialfilter transformer, but it doesn't work as expected. Geometries that i'd like to test were set as Candidate, the area as Filter and Tests to perform to Within. But it does not test for candidates within the filter, instead it tests if the filter is within the candidate, which is not what i want to achieve. Do you have an idea what I am doing wrong, or what I can change to make it work? I am using FME Desktop 2015 thx & br,mel

I've created a functional workspace based on the wonderful ArcGIS Indoors to IMDF template; Even got a reasonable IMDF dataset successfully written!  In my ArcGIS Indoors model, I don't have any data in the "Sites" feature class (IMDF: venue.geojson) but it's handled in the workspace (thanks!). A little massaging of my source data solved that problem! Unfortunately, I have address data in the ArcGIS Indoors "Facilities" feature class. Since the venue.geojson and building.geojson both originate from "Facilities", and there were two rows in Facilities, this results in multiple (3) entries of the same address (okay, they have unique address_ids). I'm new to FME -- so, I tried a few things (i.e. adding a "DuplicateFilter" but then realized I don't know how to get the respective address_id further downstream).I was thinking of "FeatureMerger" (?) but it seems really magical and I can't quite figure out how/why it work

I want to get the Start, Mid and End point from: 1. A line dataset (Roads)2. A polygon dataset (Roads) What is the easiest way to process this? (The polygon dataset is in the shape of roads, so looking at the start, mid and end point of the road as we see it!)

Ok, I know this is something dumb, but rather than beating my head against a wall I figured I'd ask for some help! I have a vector data set that I am converting to a raster. No problems there. The issue I am having is each vector polygon has a value set. I want to pass the value to each raster pixel (30X30). When I use any of the vector to raster converters (mapnik, image, or numeric) rasterizers I am getting the same single raster without the values being passed. I attempted to group the features by a GUID, and value but that just created 700+ separate rasters. Any ideas on how to pass the value field to each single pixel would be appreciated. I've attached a sample of the clipped vector data.

I have 10 long/lat coordinates, 1 in each column of a CSV file, with the headers listed as follows: Y1, X1, Y2, X2, Y3, X3, etc. The final two coordinates mirror the first two coordinates, so that the shape is closed. I am new to FME and am attempting to create a polygon from this CSV file and would love any guidance offered. Thank you.

Hi FME-Experts,I'm trying to read features from an Oracle Spatial Table by the corresponding reader. Although reader option "Max Features to Read per Feature Type" has been set to 20, FME didn't stop reading. (See Screenshot) Does anybody have an explanation why this behaviour occurs? Actually I'm not reading only one table but three, so switching over to "Max Features to Read" is not really an option. With this option, reading would really stop after the given number of features has been reached. (but only for one Feature Type) Looking forward to your answers!(FME Desktop 2022.1.1 Build 20220728, identical behaviour in FME 2021.2)

Hi, excuse me for the interruption. I have one problem and maybe you can give me some advice.I have .las format cloud point where buildings are filtered and I want to get 3d roofs (or building and roofs) as output. output:

I am building transformations that send data to Azure Table Storage. When the attribute value is missing there is a blank string inserted into the table. Due to the nature of the feature, there will only be one row of data but different columns may have missing or null values. These values we do not want written to the table. I have tried using Python and NullAttributeMappers, but these still leave the <missing> value which is causing issues. Is there a way to dynamically remove these columns? The reason for wanting to remove the attribute columns before the Azure Table Storage writer is that "Automatic" Attribute definition appears to be required in order to dynamically pass different columns to Azure.

Hello, I am new in the FME community but with a great experience of FME Desktop which I would like to share with you. I don't know and I do not understand how to make and publish the article on the page. Could you help me, please?

I have a single band raster (DEM raster) I want to create polygons which represent ranges. For example I have pixels with a range from 100 - 500 and I want to create polygons where values are in the range 100-105, or 105-110. I've tried to contourGenerator and building areas from those but contours aren't close so it's not really an option. RasterToPolygonCoercer I think would work but I need to first get my raster values to be grouped by the interval - this is where I'm having trouble. any ideas?

I am able to convert Autocad dimensions to “Arcmap” dimensions following the response of @Mark Stoakes​  : https://community.safe.com/s/question/0D54Q000080hgppSAA/migrating-dimensions-from-autocad-to-esriHowever if I try to write dimensions to a geodatabase with an ArcGIS Pro geodatabase template, I get this error : |FATAL |GEODATABASE_FILE writer: An unknown exception occurredI read that is not yet supported to read “ArcGIS Pro dimensions” with FME : https://community.safe.com/s/question/0D54Q00008wRTK3SAO/getting-error-like-unable-to-convert-row-to-dimensionfeature-while-reading-a-dimesions-fileIs it also impossible to write dimensions to an esri geodatabase with an ArcGIS Pro geodatabase template ? You’ll find my fmwt in attachment.Any advices is welcome 😊Laurent

I'm working with a date field that needs to be converted from a text string giving the format as described in my title (e.g. October 1, 2022). I've found a lot of documentation on the DateTimeConverter, however none of the formats on the documentation seem to match up with my date format. This seems like a simple solution that I'm missing, any help is appreciated!

If so, what parameter settings would accomplish something like the attached example?

I would like to modifiy the last vertex of each line feature, if the lines intersect, to copy the depth so that also the connection is made in Z-coordinates. Based on an attribute field there should be determined if the Z-value should be copied or overwritten of it's connecting neighbour.
