Transformer(s) to test multiple attributes in multiple input files

I have two input files, and I want to check whether or not the address in one input file (comprised of a street attribute, number attribute, postal code attribute etc.) matches the adress in another input file (also comprised of more or less the same columns). It's a string/text object, so I don't need it to be an exact match.I've already tried feature merger, but it seems as if feature merger only accepts exact matches. I could be mistaken of course.

No clipper supplied for group and all clipees will be treated as OUTSIDE

I have line feature which I have cut down from the administrative boundary and I need the result which have only the administrative Areas outside of line Buffer Areas.I used Generalizer,Bufferer, dissolver then Clippers("Clippers First" to the Clipper Type parameter in the Clipper). Dissolve areas are in Clipper port and the administrative boundary areas in the Clippee port, then shows this error and all dissolve area comes on the rejected port of Clipper and output is written only the administrative boundary.ClipperVector(ClippingFactory) Extra clipping feature encountered and ignoredClipperSolid(SolidIntersectionFactory) No clipper supplied for group,all clipees will be treated as OUTSIDEhave anyone any suggestions?

Why the Clipper transformer is too slow?

Hello everyone,I need the [B] (Green) areas, the administrative Areas outside of road Buffer Areas. Be precise, I need an area which have no Road.Therefore, I used:Bufferer -> Generalizer -> Clipper ("Clippers First" to the Clipper Type parameter in the Clipper)->Buffer areas are in Clipper port and the administrative boundary areas in the Clippee port and output is Esri Geodatabase (File Geodb API).Unfortunately, the Clippers is too slow. After 14 hours, it finished only (clipping group 16985 / 33079)I have total 60001975 buffer road. How can I improve the speed of the Clipper and get my desirable output.Thanks

simple txt to coordinate

Hi, I have a simple txt with many coordinates like (no header):554174.746999408, 5598075.08612377, 554175.302999408, 558090.53212377, 554177.963999408, 5598129.63312377, 554182.011999408, 5598160.71912377, 554182.176999408, 5598181.49312377, 554180.422999408, 5598212.50312377, 554172.863999408, 5598249.02912377, 554167.975999407,I want to validate that geometry. I tried using different readers (txt, csv) and transformers like stringreplacer. I found this question https://knowledge.safe.com/questions/39344/use-of-the-geometryreplacer.htmlbut could not modify my workbench with success.Any hints on that?

RasterExpression

Trying to get some calculations done.But as soon is the band and the attributes are combined the calculation fails.The pic shows the expressions.The first 2 get a values rest drop to No Data.Tried rounding using int8, 16 etc. , ceiling. Every time same result.Tried different interpretations.The input is a DEM; min= 0 and max 519 (Real64) Any tips on this?The calculation is a non-iterative variant for gradients. These work neatly in python script I made (did not invent the calculations , mind you)tx for any thoughts!

Splitting ArcGis Annotation with multiple words

Does anyone think it is possible to take annotation that is a single feature but contains multiple words (of different rotations) and create a new feature for every word with a new textpoint geometry and rotation for that word?For example the following is a single piece of text that is curved to follow the road.I want to separate this into two objectsNew location for the second wordNew rotation of the second wordI haven't attempted this yet but wondering if its something that could possibly be achieved in FME Thanks

Set cluster tolerance during intersect

   I am new to FME and need to perform an intersect with a specific cluster tolerance. In ArcGIS Pro you can set the cluster tolerance during an intersect (http://pro.arcgis.com/en/pro-app/tool-reference/analysis/intersect.htm) but I don't know how I can reproduce this in FME? The clipper does not have this option and there is no "cluster tolerance" transformer. Any suggestions?

Retrieve an attribute value from another shape in the same workspace ?

In a workspace, I retrieve by spatial relation (AreaOnAreaOverlayer followed by a Sampler, SpatialRelator after InsidePointReplacer, ...) an attribute value in a table and a shape that have nothing to do with the table and the source shape. So I create a second workspace in which I retrieve the previous attribute value in the table and the original shape by a Joiner.  How can I do this in one workspace?

Best practice - reading a zipfile on FME Server

This might be the most stupid question ever posted but I do find this problematic. I've had difficulties with this many times over the years which leads me to the conclusion that I'm not using best practice. On FME Server (Windows) I want the user to input a folder and then I want to read several pdf-files (for uploading to S3) from this folder. When run I get all errors despite how I format the path. So, I'm guessing I have configured FME Server wrong. I've tried UNC-paths as well. This will be a difficult task to solve in this forum I guess.Another option would be to input a zipfile with all the pdfs neatly zipped into it. What would be the best practice for this? That is my question.

Why Generalizer Failed to write feature class and Dropping containing feature?

Hello everyone,  I am working with line geometry as a reader. Then i buffered the line feature and used generalizer (with Algorithm: Douglas Generalize, share boundaries: No, Tolerance:30), to simplify the buffered line feature and need a output with Esri Geodatabase (File Geodb API). But it shows the errors:Failed to write Geometry to feature class 'way_r' with geometry type 'esriGeometryPolyline'. Dropping containing featureI have also attached the ERROR text. Please help me.Thanks.

Spell Check attribute values

Hi ,We have 100's of layers and to maintain the data quality we have to perform spell checking on the attribute tables. So my question is is there any way we can check all the attributes string values through FME or is there any spell check transformer. There is always a possibility to have typo or misspell, so cleaning thinngs using FME will be great.

Where can I find the records that were dropped because they snapped into a single point in snapper

I have been running a script that uses snapper and get the following line in the log:2018-01-23 08:08:01| 42.7| 0.0|WARN |Snapper(SnappingFactory): Processed 83703 feature(s). 10930 were snapped, 72770 were untouched, and 3 were dropped because they snapped into a single pointI have tried to find where FME lists the 3 dropped records, but have been unable to. Snapper only has Snapped and Untouched as output so I can't just add an inspector to it.

How do I subtract rasters with different dimensions?

Hello,I have one raster who's extent is smaller than another, but I would like to subtract one from another with the resulting raster the same extent as the smaller one. I get this error when using the RasterCellValueCalculator to subtract them: RasterCellValueCalculator_Evaluator(RasterEvaluationFactory): Raster A has '12392' rows and '4022' columns, whereas raster B has '12435' rows and '4065' columns.

String Replacer with Regex in Condition Statement

Hello, I was trying to use this transformer to replace some matched patterns but I cannot get my head around how this should be working. I am confused about having the same fields to fill in both under TextToRepace Condition Statement and the TextToReplace.  What I want to accomplish is to obtain the City name from the below text strings. As you can see, I have 2 cases that need to be solved:  #1 - replace "^S2_XLS_\\D\\d{3}_" with nothing #2 - pull out "(?!^\\w\\d{3})_\\D+?_" from the rest of the cases. I find it a bit hard to understand how this should look, chained in/or the Conditional Statements of both "Text to Replace" and "Replacement Text".  Can anyone point me into the right direction?  I very much appreciate this.

How to Aggregate and Group By Non-Contiguous Features

I have a dataset of bikeway segments that I want to aggregate and group by name and type. For example, I want all "Heather" and "Protected Bike Lanes" to be one group. However, the aggregator joins non contiguous lines when it groups. As shown, there is one feature for both segments that have this name and type.What I would like is to have two segments here. In other words, group by name and type, but only join if segments are within some reasonable threshold, like 10 meters. Is it possible?
