Transformers

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 scenari

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?

Hello, I've a question about SQLExecutor and SQL statement. I'm upgrading workspace from FME 2017.1 to 2020.1 and in 2020.1 I'm getting an error in SQL WITH statement. In FME 2017.1 this code is not rejected and works. Error with example 2020-07-22 14:35:49| 3.1| 0.0|WARN |Error executing SQL command ('declare "public_custom_query_crsr" cursor for WITH something AS (...)INSERT INTO table (a...'): 'ERROR: DECLARE CURSOR must not contain data-modifying statements in WITH What has changed in SQL Executor from 2017 to 2020.1? The transformer version is the same as I see (version number 8). I use the same database How can I change my SQL, is there a need to modify mine WITH statements?

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 result Can you help

I am trying to follow the guide at this link https://community.safe.com/s/article/how-to-read-all-feature-classes-from-multiple-esri But 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

Hi I'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?

I have a large polygon SDE feature class (>3M features) from which I only need polygons intersecting a few Oracle polygon features. I've connected the Oracle features to the SDE FeatureReader's Initiator port and I'm using them to filter SDE data with the 'Initiator Intersects Result' spatial filter. I've realized it returns duplicates when there's an SDE feature intersecting more than one (non overlapping) Initiator feature. So if an SDE feature intersects 3 Initiator features I get 3 copies of the SDE feature. This is not what I would expect. My only option is to use a DuplicatFilter right after the FeatureReader but when reading thousands of features this will slow down my translation. Has anyone come across this same problem?

Hi All, Appreciate if someone in this forum let me know the process to transform Enghouse Cable Cad files to any OGC format with attribute data transformation. Thanks in advance. Vijai Gunalan

i have different points (A,B,C,D,E,F,G,H,I,K) . some points are connected together and some not in the network ,as example A connects to B connects to C D connects to E C connects to G F connects to I connects to K if there are any connection between any point , i want to use shortest path finder ,depend on the shortest length and the largest value in specific attribute . soi am not sure how could i let the shortest path finder pick only and choose the largest value of attribute if he has multiple path and the transformer should decide FME 2018 Thanks for help

I am trying to extract vertexes from a shape file that has 3D Lines with both a Z value and an M value. I am trying to extract the both the Z and M value but I don't see a way to do it. Vertex Extractor will only give me X,Y,Z

FME 2017.0 (17271). I have a polygon layer which consists of an area with buffer zones around it. The polygons do not overlap. I also have point data of address which covers a larger area and includes postal and non-postal addresses. I want to select only the postal addresses that fall within the polygons. The address data is stored in SQL Server using the Geometry data type to store the locations (WKB Geometry). So I've been comparing ways of doing the selection. In doing this I've found that using FeatureReader with both a WHERE Clause AND a Spatial Filter results in some address records being selected twice. I read in the polygons then send these to the FeatureReader. The FeatureReader connects to Microsoft SQL Server Spatial to read the point data. The Spatial Filter is set to "Contains". If I leave it like this and add a Tester to do "Postal NOT LIKE 'N'", I get 653,819 records. If, instead of the Tester, I add a WHERE Clause to the FeatureReader, I get 654,305 records. This is a

Hello there, I am trying to aggregat neighborhood polygones (they need to touch or intersect each other) grouped by their ID with the condition, that the value of a specific attribute from the neighbor polygone needs to be in the range of +-10% of the „motherpolygones" value. In addition, I need to use the „Attributes to Average, Weighted by Area“ attribute accumulation setting from the aggregator. This option isn’t available in the neighborhoodaggregator. Also the "Attributes to Concatenate" option is necessary. In words the Transformer should do this: "If the polygones has the same ID and touches or intersect each other and the value of the attribute AA is in range of +-10% aggregat them. Weight the BB attribute by area and concatenate the attribute CC." Does someone has an idea? best regards, knigge

The highlighted Polygons should form a larger polygon with the same attributes. Both have different IDs, so after merging only one should be retained. The same transformation needs to occur for other polygons in the screenshot also. Usage of Dissolver and FeatureMerger transformers has not yielded results. I hope some light can be shed on the right approach to take here.
