Transformers

I'm trying to merge photos together (similar to raster mosaicking) but they have no overlapping features. Their file name shares a common value which I would like to use to merge the photos, but I can't seem to find a transformer/group of transformers to do this? Thanks

Hi, I would like to assign a unique count as a new attribute, based on the value of an existing attribute. I cannot find a solution: Counter, UniqueValueLogger and StatisticsCaltulator seem not be suitable for this. It is a large database. How do I manage this? I am not interested in the number of Pete's, Daisy's. Example: Old attributeDesired attributePete1Pete1Jacob2Daisy3Daisy3Daisy3 Sieger

I have an aggregate of 4 3D lines which are the outline of a vertical polygon. I want to replace it by a face and can't seem to do that. (In fact it is a wall of a building) I need LineCombiner to create a polygon which is prerequisite for the FaceReplacer. As it seems to me LineCombiner cannot handle vertical polygons and so I cannot create vertical faces. Please proof me wrong or let me know how to solve this.

Hi, Is there a way of finding the min x, max x, min y and max y cords of a DWG file without reading the whole file and then using 'BoundingBoxAccumulator'? The file is very large so I don't want to have to read it all first. I am using FME 2017.0 64 Bit Desktop. Thanks!!

Hello, I was initially running a python script outside FME to prompt a user for a said city to download data for. I would like to integrate that script as a "Python Startup Script", in FME 2017.1. I am stuck right at the beginning where I want the user to mention the city but the input caller stops the progress of the translation and the console log is waiting for something I am not sure how to enter. It would be even cooler if I could present him a dropdown list to chose from. county_name = input('City Name: ').title() The log window shows the following: FME_BEGIN_PYTHON: evaluating python script from string...Enter the City Name: ...aaand I cannot do anything here. Or I am not aware of the input place. Any advice on how to overcome this?

When trying to reproject the data downloaded from this site / canada - New Brunswick (shape files): http://www.snb.ca/geonb1/e/DC/catalogue-E.asp I get 2018-01-08 13:48:24| 0.5| 0.0|ERROR |CS-Map Reprojector: Unable to load grid file for 'NAD83_to_CSRS' I also downloaded the the FME Reprojection Grid Add-on at http://www.safe.com/support/support-resources/fme-downloads/beta/ but it didn't help.

I have a few hundreds of points and I'm trying to: 1) 'Cluster' them spatially (max distance 25cm) and based on one common attribute while the number of neighbors can vary from 0 to 5 2) Calculate average position for each 'cluster' of points and replace their geometry so that all aggregated points have the same position (of course keeping the original attributes). I would be grateful for a hint, I've been trying different transformers and I can't find a solution.

I have 1 area Featureclass with 700.000 square of 5mX5m and 1 featureclass with 70.000 lines. I want to know for each square how many times it is touched bij a line. I have tryed [SpatialRelator] but after 14 hours FME was stil comparing, amd i tryed [LineOnAreaOverlayer] but FME gives a memory error. Is there maybe another way? Someone suggested [InLineQuerier] but i see no options to check if square is touched by a line.Thanks for your time.

Hi guys, I've got an issue with the JSONFragmenter in FME Server 2017.1 (Build 17539 - win64). Well, I think I have... maybe I'm missing something! Any non-JSON input seems to cause the workspace to finish with an error rather than carry on : "A fatal error has occurred. Check the logfile above for details". But there's no further clues in the log : Loaded module 'JSONQueryFactory' from file 'C:\Program Files\FMEServer\Server\fme\plugins/JSONQueryFactory.dll'FME API version of module 'JSONQueryFactory' matches current internal version (3.8 20170315).Emptying factory pipeline.A fatal error has occurred. Check the logfile above for details The same workspace runs fine in FME Desktop where any non-JSON inputs come out of the "Rejected" port and the workspace happily carries on (I've got "Rejected Feature Handling" set to "Continue Translation" in FME Desktop). I've added in a Tester before the JSONFragmenter in my workspace for now, but I'm curious as to why this is behaving differently i

Trying to write from SQL server to MongoDB. It has a below structure: Geometry Type Coords [ [ [ [long, late], (pt 1) [long, late], (pt 2) ] ] ] Can we store all the polygon data like the following: Geometry: Cords: [ [long, late], (pt 1) [long, late], (pt 2) ]

Hi all, I'm new to FME and am trying to deal with a datset that has duplicates in. However each duplicate contains some information that I need to preserve into new columns. A simplified version is something like this: PropertyIDAddressContact nameContact details00011 High StreetMr Smith0121232800000011 High StreetMr Jones0121232800100022 Low StreetMr Birmingham0121232800200022 Low StreetMr Warwick01212328003 And what I need to end up with is more like this: PropertyIDAddressContact nameContact detailsContact name 2Contact details 200011 High StreetMr Smith01212328000Mr Jones0121232800100022 Low StreetMr Birmingham01212328002Mr Warwick01212328003 It's been suggested to me to use FeatureMerger after multiple DuplicateFilters, but I can't figure out how to bring each set of filtered duplicates back in to a single dataset whilst preserving the data out of the duplicate entries. Any help, pointers or example workspaces would be greatly appreciated. Cheers, Mark

Hi, I want feature count in a variable, I am using statistic calculator for this purpose but it ask me for attribute to analyze but i want count for all features. I guess the below links are explaining my requirement. https://knowledge.safe.com/idea/45903/add-a-count-attribute-to-the-featureholder.html https://knowledge.safe.com/idea/48591/save-feature-count.html Regards, Dheeraj

Hi guys, i am trying to import some surveying data into a file geodatabase which requireds to have some standardised schema and unique identifiers.Because there are about 200 feature classes to read and 30 feature classes to write it's not very realistic to set up tester for each of them.. I have created a lookup table which include the feature classes names for the both source (from surveyed data) and final dataset. as well as the required field name and value for unique identifier Because there are other fields required in the final dataset, i have created a fie geodatabase with all reuqired schema so hopefully there is a way i can just import the source data into it. Thanks in advance and a late happy new year to everyone :)

I have a workspace where I am trying to read and write to a SQL table (ArcGIS line feature class). The reader is an abandoned line feature class that contains a length column (double, 38 precision, 8 scale). The writer is an active line feature class that contains the same length attribute set to the parameters listed above. When trying to write features from one to the other I get the message "Column 'length' of type 'double' specified in mapping file but not defined in existing table". There is an older post regarding this topic but it did not provide an answer, it dealt with creating a new feature class. My workspace is simple, it contains two readers one is the abandoned lines and the other is a cad file; I use a NeighborFinder to select only the abandoned lines that match the cad file; I have a TimeStamper and AttributeManager after the NeighborFinder; then the writer. I have tried using the length calculator and setting the value to that in the attribute manager but continue to g

Salesforce Reader/Writer in FME don't support read type base-64 data from Salesforce. So except salesforce reader, is there any way to read type base-64 data from salesforce by FME?

Hi, I'm fairly new to FME and am hoping to tap into your knowledge! I'm trying to score roads depending on their safety record. The criteria is 4 KSI (Killed or seriously injured) collisions within a 1000 metre stretch of road in a rural environment, and over 500 metres within in urban area, over the previous three-year period. I have a dataset containing collisions across the county over five years, which includes coordinates, severity and date (so i can easily filter out those that are too old or not serious or fatal - 820 collisions after filtering). I have a Mitab file containing the roads (with a unique reference and a field for urban / rural) - but the lines indicate the centre line of the road and as such they do not join at junctions. We're talking about 27,570 links so I can't change this. I can conjure up a way of seeing how many collision points have another 3 points within a 500 or 1000m cluster, but I'm stumped as to how I can link it to stretches of road? I'm using FME de

Hi, I need to find the gaps between two polygons (not auto - correction). Kindly let me know which transformer I have to use? Thanks in advance Regards, K.Jayakumar

How do I get the version of the transformers in my FME-Version? I'm using FME(R) 2016.0.1.1 (20160224 - Build 16177 - WIN32) and I just got a workbench that someone else made. When I try to open it, I get the following errors: Found transformers in this workspace that are not on your system: 'Dissolver (version 13)' and 'AreaOnAreaOverlayer (version 5)' Both this transformers do exist in my FME-version, but they are probably of an older version. So how do I know, what versions I'm using? What version of FME are the transformers with the above versions part of? thanks, Vera

Hi there, I am trying to write text values imported as attributes to a PDF, and want my text within the 'description' attribute to wrap when it reaches the edge of the page. I have tried to use the TextWrapper transformer, using the bounds extractor values, but no luck. Screenshot below shows the resultant PDF from the above workbench, with title text (Site Diary) and the description as per the transformer below. I've tried adding in the PDFPageFormatter but this doesn't seem to make any difference Any suggestions? Many thanks

def processFeature(feature): roleList = feature.getAttribute("tag{}.k") print(roleList) if roleList!=None: for feat in roleList: print(feat) Above is my quite simple python code that successfully prints all key-values for the tag-list of OSM features. This works the same way in 2.7 and 3.4, as expected. However, if I change the attribute to print the member list instead, I get different behaviors between the two. With the following code: def processFeature(feature): roleList = feature.getAttribute("member{}.ref") print(roleList) if roleList!=None: for feat in roleList: print(feat) It prints nothing in Python 3.4 compat-mode, but does in 2.7 mode. How come this happens? My initial thought was that since the member-list only contained one member, it would not treat it as a proper list, but even on features with several members, the behavior is the same. My current workaround is to quite simply use Python 2.7, but this might not always be a good solution.
