I would like to transform a GeoJSON link into a line feature

Hello everyone, I'm currently trying to make a path from a GEOJSON "link" which was return from a HTTPCaller. Is there any way to transform the link below into a line feature? Thank you in advance. This, below, is the GeoJSON file in question.https://docs.google.com/document/d/1-H6F53Z3Mpu9qmOLQwvifWVPuG7xgjtk4aekHyG1nUU/edit?usp=sharing

How to segment a line from a particular point and continue segmentation as the line branches.

Hello, I'm working with Ordnance Survey data, in particular their OS MasterMap Highways Network RoadLink and RoadNode datasets. This is a topologically correct link and node dataset. I'm looking for a way to segment the RoadLink polyline dataset at 25m intervals up to 100m starting from RoadNode points marked as roundabouts, as shown in the example image below.My intention is to merge all lines with the same road name and road number using the LineCombiner transformer and then use the Chopper transformer to segment the lines at the required intervals. However for this to work, I need to be able to orientate the direction of digitisation of the lines away from the roundabouts nodes, as the chopper will do it's chopping in the same direction as digitisation. I can then chop them starting from the roundabout point and up the line away from this point.  My main question is, is there a way to use a point that lies on the end of a line and identify if the line is digitised toward

Workbench and Data Inspector recognizes features differently

Hi FME,I am working on a Microstation V8 DGN file with DGNV8 reader. Some of the polygons are recognized differently in Workbench and Data Inspector as attached in the images. Is this a known issue? For example, the green polygon in the Workbench (see the attached image) is losing some of the boundary edges when compared to the same polygon drawn in the Data Inspector that is showing the correct shape. I changed Workspace Parameters > Advanced > Preserve curves "Yes -> No" and then "No -> Yes". But neither was successful.  Since the feature shape is wrong at the reader level, adding transformers after the reader won't fix the issue.  Do you have any ideas on this?  My FME Desktop Version is FME(R) 2020.2.3.0 (20210129 - Build 20820 - linux-x64) and running on Ubuntu 20.04 LTS.

FeatureJoiner - 1 attribute fails to join

I am hoping someone may have suggestion as to why a FeatureJoiner fails to join on 1 attribute only.Left input: table of records, including CouncilRegion attributeRight input: polygon feature class with Region's NameThe transformer successfully joins all records from the left input table, to the feature class..., apart from the table records in "Hawke's Bay"The join is successful for all other records. I have trimmed any potential white space at the end of the attributes.Anyone can think of where the problem may lie, what test I could do to ensure Hawke's Bay records do join?Many thanks

How to relate to attribute filters?

PL.shp with attribute 1 Excel with Attibute 1 and Attribute 2Attribute 1s relateI have AttributeFilter set for Attribute 1 to extract Attirbute 1 from PL.shp I need to relate Attribute 1 to Attribute 2, which was not in PL.shp, but is in a related Excel Once the relate is attained from 1 and 2, I need to create a shp that retains the name of Attribute 2 which is then written into a folder with Attribute 2 name.  This will have to be done 200 times, so how can I efficiently get from reader to writing 200 shps that need to be in attribute 2 named folders?  Then from there, the shp needs to be created into an excel that is placed in attribute 2 named folder.

Vectors not being read by AffineWarper in FME Server

I am using an AffineWarper to translate some co-ordinates based on a series of control points. My control points are stored in a CSV file containing the following columns: Start_X, Start_Y, End_X, End_Y These are a series of control points representing start and end locations for the transformation. These are turned into vectors which are the vectors for the AffineWarper to perform it's transformation (see screenshot). This works fine on desktop FME, but when I upload the workspace to FME Server and upload the same CSV file, I do not get any features written. I get a warning in the logs saying the AffineWarper requires a minimum of 4 points, when the file does have at least 4 lines. I have written the outputs of the PointAdder and I can see the 4 vector lines being correctly created. However, it doesn't seem to be getting passed into the AffineWarper?

Esri Geodatabase (ArcSDE Geodb) Reader with Archive Where Clause (GDB_FROM_DATE/GDB_TO_DATE): Handling of fme_db_operation Where-Clause for attributes of type date/timestamp

I am reading from an Esri SDE GeoDB (ArcObjects) and use Archive Where Clause with GDB_FROM_DATE/GDB_TO_DATE to read archived data.... after processing the data, I write it to another SDE with mostly the same schema. This is my first migration step. After a while I want to do the same workflow for the data which were changed since the first migration. So I use GDB_FROM_DATE/GDB_TO_DATE in order to find the changed data in the source SDE. At the end of the second processing I need to update some of the features of the first migration (those which have been removed since the first round) and I try to use fme_db_operation UPDATE and a fme_db_operation_where clause attribute, where I try something like this:fme_db_operation_where=UUID='DEBE0707Hb000020' AND BEG='20170619110522' AND ENDE IS NULL BEG is a column of type timestamp (in the underlying Oracle DB) and needs to be compared to the value read from GDB_FROM_DATE which is of type date I get errors like the following an

I have a collection of Roads (lines) and would like to find the nearest other road(line) to the starting point..

I have used snipper to get the starting points of the lines, then I used NeighbourFinder to find the nearest line to the starting point, but i want to exclude lines with same id as my point.. It is possible with Postgis, but know that I got a license I prefer FME if possible.

Merge tables with no join value

I am trying to merge two tables with no common key. How can I do this? 1 is from a select returning the database name (dbname) and server name (srvname). For example:BlueSpark, WINSQLPRD001 2 is from a function and returns database role information. Example:sa, sysadminNTSERVICE\\SQLWriter, sysadminNTSERVICE\\Winmgmt, sysadminNTSERVICE\\MSSQL$INST1, sysadmin I want to take the two items from 1 and add them to each row from 2 such as:BlueSpark, WINSQLPRD001, sa, sysadminBlueSpark, WINSQLPRD001, NTSERVICE\\SQLWriter, sysadminBlueSpark, WINSQLPRD001, NTSERVICE\\Winmgmt, sysadminBlueSpark, WINSQLPRD001, NTSERVICE\\MSSQL$INST1, sysadmin I've tried using various transformers and all require a common key. So I tried converting the results of 1 into attributes and using that to populate the columns of the output, but it creates separate rows with the results of 1 and 2 - they are not merged such as:BlueSpark, WINSQLPRD001,,,,,sa, sysadmin,,NTSERVICE\\SQLWriter, sysadmin,,NTSERVICE\\Winmgmt

Objs to Cesium Ion via Cesium Ion Connector don't have geolocation

Hi,See attachments for my pipeline. In the pipeline I have a simple 3dmodel and a some amount of random generated points in a certain area where to populate that model to. The pipeline seems to work all the way to the end. If I inspect it in FME, everything is in correct place on the map, but once I send the obj to Cesium Ion, it no longer has the geolocation data, and it wants me to place it by hand in the Cesium Ion Portal. Any idea what might be wrong? If I open the obj that I just generated again in the FME Desktop, it shows the models on map correctly.     https://cesium.com/docs/tutorials/import-3d-models/

StatisticCalculator multiple Attributes

Hi everyone,we have installed the 2021 Version already but now we don't know how to select multiple attributes in StatisticCalculator. In earlier versions i.e. 2019 it has been possible to select multiple attributes by clicking on the 3 points, unfortunately I can't find this option in 2021 Version. Do I have to select all my 100 attributes if I need a statistic about them? 😖  Is there any possibility? Kind regards,Sandra

Blocked Looping stuck in a continuous loop

I have a custom transformer to fit rectangles into a polygon. The inputs are the polygon, and the rectangles. They go into a spatial filter which checks for "contains within", failed features are rotated and looped back to the candidate rectangles port to see if they will pass the "contains" filter again. I set the "maximum number of iterations" parameter under advanced to equal 4. The issue is that the transformer will just spin the failed rectangles infinitely instead of just 4 times.

Finding distances between buildings using neighborfinder?

I have a 2D polygon shapefile representing buildings. I want to determine the distance to and from each building. I have tested the neighborfinder and think that may be strategy however I tested one building as the candidate and all other buildings as the base. However I do not want to create separate building polygons to use and rerun the transformer a couple hundred times. Is there a way to use the full building set as both the candidate and base?

Use list of files in Excel to copy into a ZIP file

We have a set of DWG files covering our geographical area. Sometimes we need to supply contractors with a subset of these files. The files are named by their map reference. We can generated a list of the required files using our GIS. So we have an Excel file with a list of these tiles in, which are also the file names of the DWGs. I have built a Workspace in FME 2020.1 to read the Excel file, construct the path and filename, and pass it to the FileCopy Writer. This successfully copies the files to a folder, but when I try to get it to ZIP the files, I only get some of them, and this message appears in the log: 2021-05-17 17:22:04| 13.4| 11.2|WARN |MULTI_WRITER: Skipped adding of some files to zip file 'X:\\SomeFolder\\selected_DWG_files.zip' because they already exist I don't understand the error because all the DWG file names are unique.
