Cutting a polygon using the shape of another polygon layer?

Greets, Any idea to cut the polygons in the layer 2 based on the polygons in layer 1 in the same shape and close or same ratio of cutting , please note that there is a shifting between tow layers.or move the polygons in layer 1 to match the location of polygons (based on corners) in layer2

Dynamic buffer size from polygon

Hi all!I have a polygon where every vertex/point (don’t know the correct termonology) has a xyz coordinate. I would like to create a buffer where the buffer size depends on the z-coordinate. Couldn’t figure it out how to do it. Anyone who can help me figure this out?

Get minimum and maximum post dissolve

Hi, I have many polygons with height attribute. I need to dissolve the adjacent polygons and keep the max and min height of polygons dissolved. The problems it’s the quantity of polygones that are dissolved it’s random, can be 2, 5, 50, 100 or more. I made a dissolve with generate list, then a ListSorter but then I don’t know how to get automatically the min and max. I think to use attributeCreator with Arithmetic Editor after the ListSorter but I don’t know how to set it to get systematically the min and max of entities dissolved Thanks

use SurfaceDraper in parallel mode? I have a large tin and it is slowing down the workspace tons!

Hi, I tried it with a mod counter, Inputs seem to work but no output at all comes out of the custom transformer. I am passing all attributes (not many anyway) into the custom transformer. It makes no difference I am trying to add a Z value to each point (frorm vertices). With the TIN I get a much cleaner result than with a raster, but it slows down the entire process x4. Thanks in advance for any suggestion.

GetFeatureInfo from a WMS workaround?

Hello,So I am having the time of my life with Italian WMS’s 👌 and some of them even have some table data queries connected to them. I would however like to get the table information for more than one feature at at time, instead of opening in PRO and click each polygon and collect. Knowing that FME does not support standard GetFeatureInfo yet then I’m speculating if someone has created some artful way of achieving this anyway (sure there are plenty of those).So far my idea is to fetch a center point for each of my respective polygons, do coordinate extraction and then add those values to a standard HTTP based GetFeatureInfo request with some FME string gymnastics. The WMS in question is this here:https://wms.cartografia.agenziaentrate.gov.it/inspire/wms/ows01.php? The layer being:CP.CadastralParcel And the information being fetched from the query being:InspireID LocalID InspireId_namespace Label NationalCadastralReference All suggestions what would be the best way to achieve this in re

Poor performance when updating data while good performance when inserting new data.

I have a dataset of around 200,000 records (point geometry with approximately 10 attributes).I am using the Change detector transformer to update only those records that are updated and to add new records or to mark some as deleted records.I am using the Feature Writer transformer to write the data into an ESRI Enterprise geodatabase in MS SQL in Azure Cloud. Source data resides in the same geodatabase in Azure Cloud.!!! FME Server is installed on premise, not in Azure !!!When initializing the ETL by truncating the destination table and initial loading of the data, the 200,000 records are written in about 7 minutes.!!! There is an index on the attribute that is used as Primary Key and that attribute is indicated After the initialization, the time to perform the ETL is still low (5-8 minutes) if there are no updates on data, or if there are few updates.However, if there are many updates (i.e. 100,000 updated records) the time increase dramatically to 4 hours.Data is written in 3 tables:

I am updating from FME 2014 to 2021 and have a question. I am translating from Smallworld 5.1.6 to MicroStation V8i and I am having problems with the text scaling.

Translating using 2014 igds_text sixe 8 translates to Height and width 0.08 however translating using 2021 using the same parameters it translates to 0.00 and if it is a multi line text with 3 lines of text it translates to 0.03. I did try other scaling sizes even up to 20 and the results were the same. Please advise Since I need to do an upgrade and don't want to have to redo all of my text items I installed and tested FME 2017, 2018, 2019, and 2020.. It appears that the text change happened in release 2020. I can use the same FMW file that I created using 2014 and it works fine for 2017, and 2018.. I did have a glitch using 2019 but once it ran the data was correct. Starting in 2020 the text sizes were all messed up. I am hoping someone can advise me on what may have happened.

Needing to create a line between two points that have a key tie

As the title says, I have two different point feature classes, and then a table in the geodatabase. Point A has a unique field value that matches from the point to a record in the table and then, that record in the table has a unique value that matches to Point B. I want to use this “connection” and the vertexcreator transformer to create a line from Point A to Point B, for situations where they match, but I am stuck at the moment and can’t seem to connect the dots. Pun intended.

In FTPCaller, downloading a file transfer as Attributes rather than a physical file and accessing/referencing the Attribute data

I have been tasked with connecting to an FTP site, retrieving a csv file, parsing that file into multiple Excel worksheets within one workbook and then FTPing the Excel spreadsheet back to another FTP site.I have all the component pieces working, in 6 different workbenches, the download of the original csv file, the parsing and writing of the data for each Excel sheet and creation of the four individual worksheets and the upload to the destination FTP site. However, I have been advised by the local FME Admin that the process should be housed in one FME workbench. And in order to achieve that, instead of downloading a physical csv file, I should be downloading the data as an attribute so that all of the subsequent processes could be housed within one FME workbench and the attribute data shared by each subsequent process, leaving no artifacts at the conclusion of processing.I have created one FME workbench and copied all of the processes into it and made all the adjustments to User Par

Attribute Exposure in SQL Executer

I am using SQL Executer but in the output port I am not getting the attribute exposed automatically. My SQL expression I am only counting the inputs so I cannot expose the attribute using “Populate Attribute from SQL”. I cannot use Attribute exposer every time I am using the SQL. Is there any other way to do this.

Shortest path between multiple from and to locations

I have about 20,000 adresses and 10 locations of the same sort of destination (eg. a doctor). I have already a network.I'd like to calculate the shortest path between each adress and the nearest doctor over the network.Is there a way to utilize the shortestpathfinder for this?I tried the fromToBuilder to create from-to-lines. However, the fromToBuilder requires a join field for each from and to location. Which I would then have to create manually for each adress (and so create 200,000 paths; 20,000 * 10). The shortest path could then be recalculated after the shortestpathfinder to get the closest doctor for each house.Is there perhaps a more efficient way to do this?

DatabaseJoiner looses curly brackets in joined attribute

I am using FME(R) 2022.1.3.0 (20220928 - Build 22630)I noticed while working with ArcGIS Data (FileGeodatabase), that when I usethe “DatabaseJoiner” Transformer to join attributes with curly brackets inside its values, the curly brackets are gone after joining. e.g. Original Attribute value: {12C300A2-64C3-4494-A1E2-430CC5C5C7A9}joined value by DatabaseJoiner: 12C300A2-64C3-4494-A1E2-430CC5C5C7A9It this a known behaviour? Why would it get rid of the curly brackets? Anything to do against it?

I did some test to write it to GIS format and those autocad_oriented_arc write ok but for some reason can’t get them to work in DWG format,I’m sure that am missing some settings in the writer because the visual preview shows those arc fine, see below: I’m using the following:FME(R) 2023.1.2.0 (20231110 - Build 23641 - WIN64)Writer Autodesk AutoCAD DWG/DXF parameters as follows: Thanks!

FTPCaller Login Rejected

Five months ago, I created a small FME application that would login to a state controlled secured FTP server and download a file to a local drive. Putty was used and files were generated for local use and for the state. That application was working fine, however, the agency that made the request was not able to approve the process in the interim.Now, five months later, when I run the application in FME, the login is rejected.If I use the exact same parameters to manually download the file with WINSCP I am able to login and download the file without a problem. Nothing has changed in the setup of the FME.In the attached image, I show the three transformers and their parameters that I used to download the file. Five months ago it worked. Now it does not. Manually, it works. Via FME it does not.I am not sure if this is problem in the FME, an issue with my local network security or an issue at the State ftp site.The error message is as vague as described in the documentation.

Repeating the same process on each group of features

I’m trying to repeat the same process on each group of features that represent each door (every door consists of many features having the same value of door_id) . on the other hand , the process that i want to create is detecting that line on green for each door and drawing it using the LineBuilder .So for exemple ,if in my input i have : 200 features , every 30 or 40 features share the same door_id value (so there are say 6 doors in total )my output : 6 features (each feature is that green line , with the attribute door_id)
