Transformers

With in the context of of using the MapnikRasterize Transformer?

How do I overlay a set of lines on an image? See below…. I cant see the lines on the image?

I have a bunch of the data in MicroStation GG format(DGN with MDB -Database).In that data we have line & Area geometry type data. & with We have common geometry with another lines in 2D or 3d as per the feature list as project requirement.Need to identify the vertex missing in the in the common geometry lines or areas,if any line has 2d or 3d snap in the common geometry then this also need to identify,If any line which is near to another line(within 10CM) this also need to identify.Please suggest the possibilities of the transformers. I have tried Line on line overlay, convert the lines into points and used point of line overlay, neighbor finder option and more . . But I am not able to get the desired output. Thank you in advance for your support. .

i have several points and i want to connect each point to another points to find the shortest path between each point and another points if exist . as shown as in image .connect Points A with B,C,D,E,F,G,H,I,J .connects Point B with A,C,D,E,F,G,H,I,J .connects Point C with A,B,D,E,F,G,H,I,J .and connect each point with the rest of the points.then i would like to cancel the duplicate connection ,as above if Point A connects to Point B ,so it is the same connection from Point B to Point A .so i want to delete the duplicate connection.i have tried to use line builder ,he connects all points together but when i used it as input for (from ... to )in shortest path finder ,and i used also for the another input network properly noded ,i got no paths output .so i was thinking that i should use vertex creator instead of line builder ,so i need to create several lines from each point to the rest of points .then i want to find the shortest length path between each point and the rest of points ,if

How dow you set an image as a background on FME and then superimpose a point cloud or polygons on top of the image

I need to do some comparison and tricks with z-coordinates in AttributeCreator transformer. Of course I can use CoordinateExtractor before AttributeCreator but it would be more useful to do the stuff inside AttributeCreator.Something like (z-value for fourth coordinate in polyline) : @Evaluate($(fme_geometry).{3}.z)

We have a geological 3D (voxel) model that contains the geological formation code for each voxel. The voxel model can be stored as csv file that contains xcoord, ycoord, zcoord and the formation code of each voxel. The x, y and z coordinates represent the voxel centers. We are able to generate a vectorized representation of each voxel cell (see image) , this is however very heavy. The goal is to create a brep solid or csg that represents all voxels containing the same formation code and sharing at least one common edge or side. These Solids may contain holes, where another formation is present. Formations may occur multiple times spatially disconnected. In this way we want to reduce the amount of elements/features and the size for visualization purposes.Kind regards, Philip

I cannot find any practical examples of this and cannot get it to work in practice.

I would like to fill polygons with Circles of a designated size. Basically show me how many full circles will fit inside each polygon. This is of course related to figuring out a maximum number of people could physically fit within the various areas of our airport and maintain a certain level of physical distancing. I could figure out some methods using the Tiler transformer but these would be squares and will impact the results. Here is a link to someone else who was trying to figure out the same issue.https://gis.stackexchange.com/questions/193482/how-to-calculate-how-many-polygons-i-can-put-inside-a-polygon

Hi Guys, As per below image, I am trying to split a complex linear polygon by its center line segments. I have not able to find a transformer to do so or any post that works for me scenario. Any ideas would be highly welcomed   For further context: I am trying to divide a polygon by 1km2.  For simple polygons, I am using Dimitri's approach within the following link - https://community.safe.com/s/question/0D54Q000080hEUV/divide-an-irregular-polygon-into-n-number-of-polygons-of-equal-or-approximately-equal-area  However, when a site is linear and complex, as the one above, I have trouble to divide the polygon correctly as I need to avoid scenario 4 below which contains multiple polygons whereas I would like to being able to divide the polygon by following an spatial logic. That is when I came up with obtaining the center line of the polygon and splitting it in different sections, which is my question above. However, if there is another way to split a polygon by specific size avoiding

So I want to remove all the shorter lines from the above while keeping the rest.

Dear All I need your help , i have now polygon represent road edge for big area as one feature (one record in the database ) and i have road center line as segment(line) , my question is how i can split the polygon (edge of the road) based on the the road center line segment ...so kindly advice , see the below pic

I have worked out how to take a 2D xyz Pointcloud and convert it using the Buffer transformer to a decent looking image with continuous sides. This sides/lines are however when you zoom in effectively polygons.  How do I almost draw a line through these worm like polygons so I actually have a set of true lines representling the original 2D PointCloud? example below:

I have an IFC file (exported from Revit) that has a transformation matrix applied to it for real world coordinates:Unfortunately, the transformation xy parameters are off by a factor 1000. What would be an appropriate transformer to change this applied transformation matrix? It might be CSmapReprojector, but I can't find how to modify my custom transformation parameters? How do those even need to look here? Thanks!

Hellow. I just want to take a simple pointcloudxyz and transform it into a polygon. it will be 2D so the z value will always be zero. Has anyone got a simple example of tutorial I can follow?

I want a more exact outline rather than a smoothed outline from a point cloud (2D) I have? See image attached at the moment I use HullReplacer which actually gives too smooth a resultCan you help

I am trying to follow the guide at this linkhttps://community.safe.com/s/article/how-to-read-all-feature-classes-from-multiple-esriBut I fail to set up the fileGDB writer 

Dear FME community,  perhaps there's an easy solution for this:  Is there a way to convert dataset of points to lines? The lines need only to be a few metres long, and the orientation is not of interest at first. Something of a PointToLine transformer...?  Kind regards Thomas

I have been trying to connect points to create lines but cannot seem to do it in either pointconnector or featuremerger.  My file has the following:  UTMX UTMY UNIQUE ID FROM NODE TO NODE  These records have duplicates where the From and To Node are reversed so you would have a duplicate going from to and to from.  I set the Feature Merger to Attributes and Geometry -build lines from points, the requestor is from the 2d point replacer as is the supplier (from same 2d point replacer transformer).  I also tried pointconnector using UNIQUEID as the break.  The former just produces points while the latter retrieves 0 records.  Any help would be appreciated.  KDMU   

HiI'm trying the tutorial / article about "How to create a WMS Service using FME Server". I've published the first workbench (GetCapabilities), but I'm having some problems with the last one (GetPNG). I've modified the FME_SERVER_REQUEST_URI to match the result from my FME Server.  When I try to run the GetPNG workbench, the FeatureReader only outputs Schema and Initiator, and not the Generic-port which are used later in the workspace. I've tried reading from ESRI Geodatabase (.sde) and from the corresponing Azure-database (Microsoft Azure SQL Database Spatial). If I try to manually select the feature types to read, I can select the ones that I've included in my URL and which is used in GetCapabilities. How do I get the generic-port to work?

Hi, I wounder what the best way could be to extract raster from geometry? In this case, extract an ortophoto from a terrain mesh. I have tried the AppearanceExtractor which works fine. The aim is to extract the ortophoto and write it as a jpeg, then read it in the workflow and replace it on the terrain via AppearanceSetter. Works fine, but I only need one feature (face) which contains the ortophoto to write to jpeg. In one test the terrain contains 62 faces, so I use the sampler to sample First N Features to get the first face and ortophoto. The problem I find is that all other 61 faces need to be processed to output "NotSampled". So depending on the terrain mesh and no. of faces this could take quite some time. I wounder if First N Feature is found, then stop processing rest of features? Hope it makes sense. Thanks!

I am new to FME and I am sorry if this question seam so basic but How can I use "CASE" statement like in SQL or "IFS /IFS" statements to do a validation logic on FME?

How we convert above mentioned format in to .las format​

I am new to fme. I have a citygml file of buildings with attribute codes such as 2100, 3400. The definition of this code is in another XML file so how do I setup the workbench so that the citygml file can access the attribute values from the XML file?
