Georeference IFC File

I have IFC data that originally used a local cartesian coordinate system. It originated in Navisworks and I used Intergraph Smart Interop Publisher to convert it to IFC format so I could use it in FME. I want to use the data in GIS software (ArcGIS Pro/Online) so will likely convert to multipatch/revit.What is the best approach for georeferencing this data/working out control points, etc.? Some of the IFC files are quite large (500MB+). Any suggestions appreciated!

Conversion from file geodatabase raster to TIFF

I have an orthophoto in ESRI GRID format stored in a file geodatabase. It works really well in ArcGIS and ArcGIS Pro; however, I need to convert this image into a GeoTIFF for a contractor that does not have an ESRI based GIS. I have tried to do this in ArcGIS Pro but I keep running into resolution and grainy output problems, and the documented fixes and remedies are not helping. As I have FME Desktop, and I have seen that FME is capable of converting raster imagery from one format to another, I thought I would give that a try...but now my output is even worse than before. Not being one to give up I thought I would come here to see how I should approach this using FME. Is there a trick to converting raster images? I thought it would be something quite straight forward (e.g. Geodatabase raster reader --> TIFF writer), but obviously the process will be a little more complex than that, at least this is my current thinking.What is the best way to convert an image from one format to

Multiple files to read as a parameter

Is it possible to read in multiple files from a parameter with FeatureReader? For example:C:/some_path/fileA.shpC:/some_path/fileB.shpSourceDataset parameter value would be: C:/some_path/fileA.shp,C:/some_path/fileB.shpBut this approach doesn't work, it gives an error.

get a given point distance

Hello,I am interested in how to get a given point distnce with FME.I have points arranged by counter (pontID is ascending) and I want to get the next point's distance. I tried NeighborFinder, but the problem is that sometimes an other point is closer,so it gives a wrong distance.Thanks!

Workflow does not Automatically Optimise Bulk Mode?

Now, ever since discovering Bulk Mode transformers like FeatureJoiner, AttributeFilter, AttributeManager etc. my WorkBench designs look radically different to my "old" ways of doing things in FME. Gone are almost all of my Testers, FeatureMergers etc.One of the things I had been meaning to test though is "Does FME automatically activate Bulk Mode where possible or do you maybe have to "Force" it? "It appears that in many workflows they do not automatically switch the Transformer into Bulk Mode!!!Example 1 - AttributeFilters (Bulk Mode capable) fed from a Tester (Not Bulk Mode capable)Takes 55 seconds to complete.Example 2 - AttributeFilters (Bulk Mode capable) fed from a Dummy FeatureJoiner (Manually forces Workflow back into Bulk Mode)Takes 23 seconds to complete despite having a extra FeatureJoiner! Here I just match on any random fields with FeatureJoiner. I'm not actually trying to Join anything, but rather "force" the workflow back

Why are all my attributes not being transformed

I'm trying to map levels names from one MicroSation DGN file into different level names in another DGN file. Most of the levels are being mapped correctly but some features are not being mapped at all. Not sure why that is happening. Has anyone else had this problem?

MapnikRasterizer Fails to Render Lines/Polygons Past Column ~32,800

Currently the MapnikRasterizer will not render lines/polygons if the output raster dataset exceeds ~32,800 columns - text and points will render normally regardless of the size. For example, if I try to process a dataset that spans 40000 x 45000 pixels, the output will be missing the rasterized lines past column 32,768.

FeatureJoiner return counts

Hi, I'm working on a workbench to report on changes made to a data set. I have a database table with a column of unique IDs. I store a previous copy of the IDs so I can compare current against previous.Using a FeatureJoiner I can establish NEW/DELETED IDs - brilliant......The issue is that I may not have Unjoined Left/Right every time so at the moment my workbench doesn't proceed.I need to get to the point where the workbench can continue/report even if either/or both are null. Is FeatureJoiner the best transformer?Any ideas? Thanks

Electric Migration workspace for Electric Asset Package V3.2 Translation Failure

Hello Everyone,I am trying to run the translation on the Electric Migration workspace for Electric Asset Package V3.2 (Electric Migration V3 2019_12_18.fmwt file) using FME Desktop version 2019.2.3.1. It fails because it is missing a file called "NapervilleElectric_2019_10_22.gdb.zip". Is the file available for download, and is the workspace supposed to produce an asset package that is ready to load into a Utility Network without further configuration?

No intersection results

Friends help me find a solution to the problem.1 There is a cloud of points falling into the field of all areas - (A, B, C)2 Areas have intersection zones - (1,2,3,4)When I start the scheme, I get the result(A + 1 + 2 + 4B + 3-1-2?-4-2-3)And I need a result(A + 1 + 2 + 4B + 1 + 2 + 3C + 4 + 2 + 3)That is, all grouped point clouds must have a zone of intersection in each result.What am I doing wrong?

Read a shape file from a subfolder in a .zip file

Can anyone advise how I can read a .shp file two sub-folders down from a zipped file? I've looked at previous posts on this group and they have suggested using wildcards to navigate the sub-folders (e.g. .zip/**/**/*.shp) but this hasn't worked for me.The .zip file is found here and the pathway to the shape file I want is below, you can see that it is two subfolders down from the parent directory:...\\HS2_Phase_2a_Additional_Provision_2_and_Supplementary_Environmental_Statement_2_February_2019.zip\\Shapefiles\\Construction_Proposed_Scheme\\CON_CN_ConsolidatedConstructionBoundary_Ply_CT05_AP02.shp The shape file reader works fine when the folders are unzipped but won't work otherwise. I've also had no luck using a FeatureReader or when the .zip file is stored locally. I'm using FME Workbench 2019.2.

How can I change the CRS for a DWG file when converting it to SHP so that it works with QGIS?

I have a DWG file that is using the NAD83 CRS and when I convert it to a SHP file and load it into QGIS the placement is way off according to the base maps I have loaded.At this point I have only been trying to do a single layer to try and figure this out but eventually I will do more layers. I am only looking to get certain geometry for now (eg layer T-CABL-FIBR-AREL-N (72ct)) and I will add attributes later.I have tried leaving the CRS at NAD83 and also tried to change it to WGS84 (which I ultimately would like to end up with).Sometimes I even end up with the geometry changed from what it used to be, sometimes minor and sometimes extreme.I've been trying different combinations of changing the CRS in FME and changing what CRS is being used in QGIS. At this point I feel I have tried every combination so there might be something else I am missing as I am still new to FME and QGIS. I haven't changed any of the settings of the reader or writer and just left them all as default bec

Create a list of dates based on starting date and interval

Hello, I'm trying to download a series of excel files that are on a website. There is a starting date of 9/19/2005 (its hyperlinked for each excel file) and it increments by 7 days (so its a page fill of hyperlinked dates). I'm guessing I need to create a list of all dates starting from 9/19/2005 so that I can use httpcaller to download each file. I'm having trouble creating the starting date so that I can use DateTimeConverter to create the range (and consequently create the full url's to each file). I tried using AttrubuteCreator with a new value of DateTimeCreate(2005,09,19) but this expression errors.Thoughts on this and I'm all ears if there is a cleaner approach. Thanks in advance

Detecting changes in attribute values for multiple feature classes.

I have got multiple featureclasses within a database, which I need to compare with the same database in the future. The featureclasses all have a GlobalID (unique value), which is the same as the GlobalID in the other database. I need to detect any changes to geometry and attribute values and write these away in preferably a new featureclass, an Excel list will also do. The "Changes" list or table should include the GlobalID of the feature, the "before" value and the "after" value. The geometry I have found is not an issue as I can use the "Change detector". However I seem to struggle with the change in attribute value, I have gone over several posts but none with a (working) answer (some links do not work anymore). I am rather new to FME myself and do not have a lot of python knowledge, I am working with FME Desktop 2018.1 and the ArcMap the features come from/go back into is ArcMap version 10.3.1. Any help or guidelines would be much appreci
