Text To Column using RegEx

Hi,I am using FME 2017.0 x64 and the input data is PostGIS data from serverSo, there is a column in the table 'other_tags that contains strings as displayed. I want the values in the left of => to be the attribute name and the value in the right of => to be the value of that attribute. The two columns are separated by comma(,).The catch is the attribute name are not in a certain order, so I found a bit of difficulty to create list.Moreover, the values in the columns can be multiple, like surface could be- paved, unpaved, asphalt, grass and many more and since the workbench has to be used for multiple countries the string also cannot be defined.Could there be some easy possible way to extract the values that can make workbench shorter and easier.I tried string searcher with regex- surface"=>".*"$ but something is going wrong.Thanks.

AutoCAD alternative label locations

Folks, I'm trying to create some polyline labels in a CAD writer but using some alternative label positions.By default the label seems to be placed dead centre on the line. Depending on the justification of the inserted text (Bottom Left, Middle Centre etc) you can move the label relative to the label point. However I want to offset the the label a certain distance from this placement.I tried to use the OffsetCurveGenerator and this almost works. However there is some complexity here. There are rules the LablePointPlacer is using to determine "which way is up" so that no matter the orientation of the polyline (drawn direction) the label is always "up" based on standard plan labelling rules. The OffsetCurveGenerator dutifully offsets lines but the concept of "left and right" based on the orientation of the drawn polyline means the offset line is sometimes "above" or "below" the target polyline.If I had to come up with some rules I&#

How to set Bylayer color in a GIS to CAD transformation

Hi,I'm doing a transformation from a gdb to a CAD that was already setup (with block name, color ect, for each layers). I'm working with the DWGStyler and its working fine. The only problem that I find is that I'm not able to put each color "By Layer". It's possible in the Linetype checkbox to select ByLayer, ByBlock or others lines types but not in Blocks... It is possible to set up the color ByLayer in that type of transformation? Or I have to specific the color for each layers?Thanks!

How can I use FME Data Inspector to view point cloud classifications?

I'm new to FME, and have been asked to look into quality control of land cover classification for processed point clouds. Currently, I'm hoping to use the Data Inspector to review the classification of land cover in las files, yet I can't figure out how to symbolize the point cloud by classification attribute. I haven't been able to find any documentation on this, could anyone help?

How do I set the import path in FME's Python interpreter?

I have a module . in a folder (called '/wscloud/email_automation/wsa/lib')I can import it if I append the path explicitly, but this seems like a very clumsy way to do this.

Add value to create new (compounded?) value

Unsure if compounded is the right term but anyway....I am trying to calculate a new attribute based on existing values - usually easy to do - but in this case the expression must reference each subsequent attribute value in an original attribute. Best explained by the graphic below:'StaticValue' is the original value and 'CompoundedValue' is the attribute I want to create. The first value will be unchanged but each subsequent value in the 'CompoundedValue' attribute must reflect the corresponding 'StaticValue' value.StaticValueCompoundedValue30030020320-50270-4023016039035425Can I do a 'circular' reference like this in FME?

How to trim the first x characters of an attribute

Hi there,the sample attribute looks like: "xxx www.mypage.com\\\\localserver.com"Between the "xxx" (the number is variable) an the URL is a blank. So I need to find the index of the first blank and trim the attribute (string) from left to that index.In addition I need to remove every character including an beyond "\\\\". Any hints? I think it will work with the StringSearcher or StringReplacer...but actually I have no idea .. :-((Thanks in advance, Stefan

Constrain Voronoi polygons to another layer

Hi all,I am currently creating Voronoi polygons (using the VoronoiDiagrammer) and I can use the Clipper to cut the polygons created using polygons from another layer (Layer B). Is there a way to constrain the created Voronoi polygons to this other polygon layer before clipping? i.e. All information in the points used to create the Voronoi polygons, should stay within the bounds of the polygons of Layer B which they are contained in. Many thanks. Edit: Please see diagram added below as a sample. I would like the create Voronoi polygons from the purple points only to the edge of the green polygons. UPDATE: SpatialFilter to remove polygons with no points within them. Clone & Offsetter (x2) to ensure there are at least 3 points in every polygon. PoinOnAreaOverlayer to insert foreign key to the points from the PK of the polygons.VoronoiDiagrammer with Group By parameter set to the foreign key field. Dissolver to remove the small triangles. Clipper to clip back to to original polygons. W

How to improve attribute validator unique performance?

Hi,I'm processing almost 200K records with more than 30 attributes and at one point of my workflow I validate if they're a unique by some attribute with an AttributeValidator. This validation is taking around 4020 seconds.Is there any other transformer that is faster than this one to do such validations ? PD: I added the profile result after running the workspace.ThanksUpdate: @MattAtSafeI added the workspace simplified with only the validations. This process is taking only 17 min for 198k records only.Here: I uploaded the file that I'm using to test in Google Drive because it's too heavy.https://drive.google.com/open?id=0B44BAUsLmbR8ZVkxRGl6SGotNGcAny help would be appreciated

MongoDB - delete record

I tried to delete the record from MongoDB collection setting the fme_db_operation = Delete.But the error is:'fme_feature_operation' has invalid value 'Delete'. Possible values include: 'Insert', 'Put'Setting the "Table Handling" = "Drop and Create" could help as bypass, just rewriting the records that should not be deleted. But I don't like that I need to rewrite something shouldn't be deleted.Any better ideas?Best regards,Irena

FME Engine is shutting down and Process Engine2 ends unexpectedly

FME Engine is shutting down and Process Engine2 ends unexpectedly while running a scheduled task. License is being borrowed from another license server. The issue is intermittent but is being observed very often. When we login to FME server then it gives error "No FME Engines are available to this FME Server." The FME Engines are available once we restart the FME server service but a permanent fix is required for this issue as it hinders the regular business process. We are using FME Server 2012 SP1.

Convert my access into a GML 3.2.1 based on an existing xsd

@DeanAtSafe @NatalieAtSafeHi, I am trying to convert to my access template into a GML 3.2.1 compliant with this xsd http://dd.eionet.europa.eu/schemas/euregistryonindustrialsites/EUReg.xsd. Our Schema is an extension of the INSPIRE Production and Industrial Facilities (http://cloud.epsilon-italia.it/eenvplus_new/PF.htm). After producing the GML, I try to validate it with this GML validator (http://cloud.epsilon-italia.it:8081/teamengine/).

Is there a way to trick (or configure) the AffineWarper into non blocking?

It seems to me that once the Control vectors are sent to the AffineWarper that a single Affine transform could be calculated and applied to all Observed Features as they come through.

Style points in pdf?

Is there a possibility to style points in the PDFStyler (scale, color, symbol)? I know I could create buffers around the points to display them in PDF but it seems so awkward to me that you cannot directly manipulate the style of the points.

Is there a transformer that allows you to pass only a certain number of features?

Hi,I have table with over 7000 records, and I only want to pass the top 10 or so for testing purposes. I know that you can specify the number of records passed in the initial Reader, but is there a transformer that allows you to do this part-way through your FME workflow?Thanks

Attributevaluemapper does not give me the field I want to map

I have a workspace that reads mulitple files with mulitiple feature types (the reader shows <ALL>, and I have merge feature type set to merge filter * and filter type Wildcard) and maps them into one table that contains all objects. I want to use a attributevaluemapper to map some integer values to some text that I will place into a text field. I cant do this as the attributevaluemapper wont show me the attribute I want to map from, and I cant write in the name of the attribute I would like to use as the source. It seems to just be listing the attributes that it has found in one of the feature types in the source files.How do I get it to give me this attribute as an option?

Is it possible to read Layer Filters (Group and Property) from a DWG/DXF?

I have an AutoCAD model that I'm trying to convert to GIS, but I can't seem to figure out whether it is possible to read Layer Filter information in any way. The model uses both Group and Property filters. Can anyone point me in the right direction as to whether this functionality already exists in FME Desktop? And if not, is it something that would be possible? I'm not even sure how layer filters are saved/accessed in a DWG, and I guess I wouldn't expect them to be attached directly to an object. Thank you!

How to mirror raster?

Here's one of them brain foods...How to vertically flip raster?Right now, my idea is to extract numbers of columns. Tile whole raster by number of columns (RasterTiler), offset them by _columns-column_number and mosaick them (RasterMosaicker). And that works...But that can be a really long proces (depending on dimensions of raster). Does anybody have any less time consuming idea?
