Creating line between points based on condition?

What I'm trying to do is create a line between the 2 weld points that share a common JOINT_AHEAD or JOINT_BEHIND common attribute and set the attributes of the created line from the corresponding JOINT_AHEAD_HEAT or JOINT_BEHIND_HEAT common attribute value. I've been experimenting with the neighborfinder, vertex creator, and the linebuilder, but was unsure of the way to go about this.An example below of the lines I would like to create between the points. Any suggestions would be greatly appreciated.Thanks,Chris

Irish Grid to British National Grid like Mapinfo

Hi, we used to have a process where we would open up some Irish national grid in MapInfo create points and then re-save the file as British National Grid. I'm trying to replicate this in FME, however when using either the reprojector or setting within the read/write i'm seeing a few metres difference. are you able to advise?

Buffer on real surface.

Hi,I am new to FME. I have a 3d surface model from laser scanning data and I want to create buffers from selected points. The buffers shuld be calculated counting the real distance over surface which will not be a rounded look a like indeed. I tried surfacedraper but the buffer polygons looks very rounded. Any body can help me with ideas ? Thanks in advance.

How to get values from a raster band and palette

I have a raster with text descriptions of vegetative classes that I wish to place on some points. I know the band and palette where the description resides (band 0, palette 2), which I have exposed using the RasterSelector. I can see the values correctly output in the Feature Information window of an Inspector but not in the Table View window of the Inspector. In other words, I can't find how to expose the values (text descriptions) as attributes. I've tried the ListExploder, ListIndexer, RasterPaletteExtractor, and Format Attributes of the Reader. I can see _band{}.palette{}.value listed as an attribute in the PointOnRasterValueExtractor so it seems all I need to do is expose _band{0}.palette{2}.value. The question is how? Hoping someone can point me in the right direction.Thanks,Aaron

donut/sliver elimination

I regularly received shapefiles from helicopter flights over wildfires where the crew was mapping the perimeter of the fire. Many times these polygon shapefiles have donut holes/slivers and I have a need to remove them as part of my workflow. I'd like to build a workspace that would detect and eliminate these types of holes but cannot seem to find the right transformer. I've tried all of the donut hole tools with no success. I wonder if anyone might have some thoughts on how best to tackle this problem?Here's a typical example of the types of holes I see. Immagine the helicopter flying back on the path it just came in on...

Is there an equivalent to arcGIS point distance? (distance between many points)

Hi! I am quite new to FME, and worked my whole career so far with ArcGIS. Some things are quite easy in ArcGIS, but super confusing in FME (and vice versa). My problem is this:I have 2 shapefiles, both with many points. Of the points in shapefile A, I need to find for each point the top 5 closest point features in shapefile B (up to a maximum distance), and also know what the distance is between these points. Furthermore, I need the attributes of both shapefiles to merge. In ArcGIS this is incredibly easy, I just use 'point distance' and state the 'input' features (Shapefile A) and near features (Shapefile B), and set the maximum distance. It then automatically give me how far points in Shapefile A are form Shapefile.How do I do this in FME? The Neighborfinder seems like the tool I should use (shapefile A = base, Shapefile B = candidates), but I can't get it to work and it rejects all features (yes, it is in the same coordinate system, and both are point shapefiles)

Handling of the TableAdder by producing multiple pdf pages

Hello everybody,I have a problem with the format of the result of the TableAdder custom transformer. I don't know how to handle the input values to get a good-looking result if the content fills multiple pdf pages. If the content fits on just one page everything is okay and it looks good but when I create more than one page FME tries to display the whole content on one page (screenshot).Tried to experiment with the Max X value and the Max Y value but nothing helps. Also tried to divide the content by counting the rows of the table and change the pdf_page_number attribute on each 50th row but the display is still zoomed out and just leaves the rest of the page empty as you see in the screenshot. Hope you can help me with that.With kindest regards,Felix

HTML 2 JPG using PhantomsJS fails when running as a scheduled task

Hi there,my question points to the SystemCaller calling PhantomJS to get a screenshot of a website. PhantomJS is installed on local drive c:\\tools and the SystemCaller ist setup properly. It all works well when the workbench is run manually. But the SystemCaller fails to execute when run the workbench from within an batchfile as a scheduled task. The scheduled task is run under the same account I am logged in with so it shouldn't be a permission problem. Actually I have no idea why the execution fails. There are no hints in the log (it just says "failed to execute...".The graphics shows the configuratio of the SystemCaller...which works fine when run manually...Any hints welcome...Regards,Stefan

Failed to locate Avenza MAPublisher installed on this machine

I am attempting to run a workspace on FME Server 2017 that writes to the Adobe Illustrator - Avenza MAPublisher writer. However, I keep getting the following error: "Failed to locate Avenza MAPublisher installed on this machine." I have installed MAPublisher 9.8 on both the client workstation, as well as the server that FME Server 2017 is installed on. I have run this same workflow successfully using FME Desktop 2017. Please advise on any solutions that may explain why FME Server is not recognizing that MAPublisher is installed. Thank you.

Can you sort files into folders using specific text in their file name?

HiI have a large number of files that are formatted like so:AA0001AA0002AA0003AB0001AB0002AB0003AC0001AC0002AC0003Is there a way to take all of these files and sort them into their respective folders using the text prefix, for example all the AA files go into a folder call AA, the AB's in AB and AC's into AC?I have a TestFilter that will do using a @Value(fme_basename) CONTAINS Test Condition for each text prefix, the output for each of these going to it's own writer, and this does work however it seems messy. Is there a better way to do this?Thanks.

The Number of Quotation Marks in Command Line on Translation Log

Hello,From this Q&A;: command line failsWorkbench generates a command line when starting the translation and prints it in the Translation Log. It's helpful, but the number of quotation marks surrounding a parameter value seems be too much when the value consists of multiple file paths.For example, a workspace generated this command line,"C:\Program Files\FME 2017.1\fme.exe" C:\FME\tmp\textline2none.fmw      --SourceDataset_TEXTLINE """"""C:\FME\tmp\data_0.txt"" ""C:\FME\tmp\data_1.txt""""""but I think this is correct, if you run the workspace from the command prompt."C:\Program Files\FME 2017.1\fme.exe" C:\FME\tmp\textline2none.fmw      --SourceDataset_TEXTLINE """""C:\FME\tmp\data_0.txt"" ""C:\FME\tmp\data_1.txt"""""How do you think about this?

Fail to convert lines to polygons correctly,

Fail to convert lines to polygon correctly,  I have applied the workbench below to first clean the lines and then to convert them to polygons. The correct number of polygons should match the number of texts. My thought is that the tools applied to clean the lines are not sufficient.  CAD file: http://www.mediafire.com/download/742ckkkp6jaxnm7/Parcels_Al_Samou_03.dwg        What other tools should be included in the workbench to first clean the lines: 1. Remove duplicates 2. Ensure lines snapping  Thank you  Best  Jamal

Port for FMEServerConsole not automatically applied during installation

Hi,during my last Installation of the current Version of FMEServer (Build 17291) to port 8080, I realized that the port won't be applied to the FMEServerConsole! So, trying to use the console I got a 404-message from the IIS . Took me a while to find the bad guy in: ~FMEServer/Clients/FMEServerConsoleConfig.txt where the hostname was still without the proper port.So correcting that to Hostname:8080 and restarting the FMEServer, solved the problem.In previous versions, this was set automatically during the installatoin. I guess this time it slipped somehow from the radar.Best regards,Thomas

Does the Data Streaming service keep an engine in use whilst streaming?

When using data streaming service with FME Server I know that an engine needs to run to generate the initial file that will be streamed. Once this file is generated i.e. a geo JSON file, is an engine involved when a user hits the endpoint to retrieve the geo JSON? Or is the data streamed from the web server?  Also, if we have multiple engines and the streaming job is run by multiple users at the same time, will they be attempting to over write the same file? Is the streaming dependent on the file that gets written by the job or does it stream directly from server?

How can I convert an Esri Geodatabase into VPF coverage?

Hello, I am a researcher working on Digital Cartography. I am new to FME and I have been trying to convert an Esri Shapefile into VPF coverage (Vector Product Format). But it seems that the FME can read VPF coverage but cannot write that. Instead FME writes VPF database which I do not want. Any useful insights on how can I write VPF coverage using FME would be highly appreciable and helpful for my research.
