Transformers

The scenario is as follows: We are able to get the dynamic segmentation done using Feature Merger & Snipper transformers based on event table and routes, but we also want to capture "LocationError" field values like similar to "Make Route Event Layer tool in ArcGIS" Any thoughts are suggestions like how do we achieve it in FME? 

I am in the process of working on an integration between Cityworks and ArcGIS Urban. While I am well-versed in using the HTTPCaller transformer for REST APIs in FME Desktop, after s few hours of working with an HTTPCaller, the only way I was able to make a GraphQL API call was using a PythonCaller with some custom code using the requests library. For now, the PythonCaller route will work well enough, but I would rather lean on the HTTPCaller for when others have to take over this integration who are not Pythonistas.

I’m trying to write data from one ArcGIS Online hosted feature layer to another using schema mapper for field mapping. I’m finding that the features from featureclass1 are being appended to featureclass2, but there isn’t any data written into the attribute fields for these appended features. Am I missing a setting in schema mapper?This is the result of my workspace (featureclass2). Features 4-7 were appended from featureclass1 to featureclass2, but the data didn’t come through.This is featureclass1, you can see there is data for those features.I’m using a csv file for my schema mapping. The schema mapper is mapping one → newfour and two → five. I’ve tried this keeping the source at

I authored some scripts years ago that use the ArcSDEQuerier transformer to query for records in a versioned 10.1 ArcSDE Geodatabase. The machine that FME resides on has FME 2019.3.1, both ArcGIS 10.1 and ArcSDE 10.1, and both Oracle 32-bit (ArcGIS) and 64-bit (ArcSDE) clients installed. The scripts have worked for years without issue. Recently, I’ve had to modify them a bit and on a development FME machine, the ArcSDEQuerier transformer works fine, but promoting them to another same-build FME machine has had some odd results. If I use the exact scripts/workspaces from the dev machine, the ArcSDEQuerier throws the error seen below. Or if I open scripts that were already on this machine, untouched, the ArcSDEQuerier also throws the same error: However sometimes, and I stress sometimes, if I open a brand new workspace and add a si

Hi Everyone, I tried to make use of the schemamapper transformer to create a new output excel spreadsheet which takes a customised schema csv file as an input. The problem is that the schema file sits within a random folder (date time stamp temp folder name - e.g. 20190903100000) each time the workbench run. (PS: the randomised folder is created at the beginning of the workflow and being passed through as an attribute value).Due to the randomised temp folder name which i tried to pass into the schemamapper as the dataset, I am not able to pass it through. I then tried to create a custom transformer where i can pass the temp folder name via attribute value > published parameter for the custom transformer. The new problem I have now is that the custom transformer does not appear to be able to pick up the attribute value (which has become a published parameter) in the dataset field within the schemamapper.It always throws an error shows "ERROR |CSV r

Hello,does anyone know why the Truncate Existing Function in Esri SDE Writer does not reset the OBJECTID Counter of a registered Table. (Table is not Versioned).SDE Writer File is based on World Parameter (not SID) and I am using ArcGIS 3.1.4 and FME 2022.2 (but had the Issue also in constellation ArcGIS 2.6 and FME Desktop 2021)The data is written on Oracle 19.15BrGoran

I have three separate CSVs (readers below in yellow) to which I have added several transformers. I first added a “AttributeFilter” to filter through two values. I then connected to an “AttributeValueMapper” to map the previous two values to given names. Then I added a “StatisticsCalculator” to sum the values within these two values. Then an “ExpressionEvaluator” to convert the values from feet into miles and after an “AtributeRenamer” to rename the field names. Lastly, I added an “AttributeCreator” to add a third field of data. This is seen in the picture below of my workflow. At the end of the workflow, I added an “AttributePivoter” in an attempt to merge all of these together before attaching a Writer and exporting the results as an Excel Sheet. I am not sure the AttributePivoter might be the best way to merge all of this. Wha

I have a raster wherein the values are in epoch time (number of days since 1970-01-01)Is there a way in FME to convert these values into different date formats, such as yyyyddd?DateTimeConverter seems to only work with attributes, but translating all pixels to polygons with attributes for the pixel value is not optimal. I would guess this could be possible with RasterExpressionEvaluator, but if someone can give an example that would be really helpful. Thanks!

Hi folks, I had some urgent need at my workplace, as the GIS database administrator working in a electricity distribution company, I was required to draft out various district data to be used by another department which will require me to decode and clean the data to enable them understand the data format based on their needs. I tried using manual method of copy and past after extracting this data from the database but it was time consuming.I tried FME and I was able to create a workflow using two transformers FeatureJoiner and Matcher and I am happy how this workflow was able to query the two excel files added to the left and right part of the FeatureJoiner transformer thereby giving me the output based on joined attributes file, one is coming as a number and varchar.  Feel free to connect with me on linkedin https://www.linkedin.com/in/anthony-ezem

Hello, I want to cut raster data with a shape data. There are 10 objects in the shape data and 10 raster data. Sometimes the objects in the shape data overlap. There is a column in the shape data that contains the names of the raster data. I want to cut each raster data with only the object with this name. I couldn't find the result despite trying very hard. I am using the clipper transformer. If you have any advice on this subject, I would be very happy.

Hello, I’m trying to create a custom chart (waterfall, combination, etc.) and I couldn’t find a transformer that could accomplish this other than PythonCaller. I’m having trouble integrating my code within FME (2022 version) which requires me to use a few packages to execute. Has anyone been able to accomplish this? I’ve already reviewed the existing FME material out there.

Hi AllA few learned gotchas in regards to GDA2020 transformations.- Dont use the Navigator to convert datums GDA94 > GDA2020 as it defaults to 7 param (unless thats what you want)- Reprojector Transformer is seemingly default to 7Param when it should default to gridshift (have a call logged with Safe)- CSMapReprojector - if you are using Desktop this is the best to use as you can force the transformation from the dropdownHowever if you are going to server and you want the user to select the output coordinate system which may or may not include a transformation you need to automate which method you use by setting it with either a parameter or a conditional value based on the selected coordinate system code  Lots of fun to be had but some caution as well. No transformation is the same.

A column name that I am trying to SELECT in the SQLExecutor is titled: STATEThe line in the SQLExecutor that contains it is as follows:I receive an error message that leads me to believe that it is not grabbing this column, and instead trying to grab the alias that I am trying to establish:Is there a reliable work around for this reserved word? I have tried using the following, to no avail:[STATE][“STATE”][state]“[STATE]”

I am looking to extract data from AGOL to store in a separate table and filter the data by its date field. Essentially I will schedule this every evening to collate all the data with todays date, or run this early morning and filter on ‘Yesterdays’ date. How do I configure the tester transformer to reflect what I need.  Any help is greatly appreciated,

Hello, I have a problem that I am struggling to get my head around recreating within FME. The images below are just for example.I have data from two separate sources for which I want to calculate the area of overlap, for each instance parcel data and problem area data.I want to calculate the area of overlap for every individual parcel and every individual problem area. So rather than calculating the overlap for every individual parcel against the entire other layer as would be the case in the image below:  I want to calculate the overlap for EACH SINGLE feature, and essentially create a list, so I can then also see the attributes for the problem area,

Hi everybody!I wrote some weeks ago about a new solution for our education department in order to get the nearest routes between one Adress and all the schools of the city.thans your answers we could make a first version of it!Now that we get more and more users we have seen 2 problems in our solution.We have a point with the adress of the student and the lines of the streets (including the way from the door of the houses to the street). Usually you have some distance between the point and the vertex of the line. To get the point to the vertex of the line we use the AnchoredSnapper (snappint type: end point snapping; snapping distance 15, Add Additional vertex: never). And hier we get 2 problems.If the point is on the line we get the result as “Untouched” instead of “Snapped” If the point is too far away we get the same problem. Is there any posibility to standarize it? I mean we want to cover all

Hi All,I have a feature class with 351 columns and need to know which columns contains ALL the records as <Null>. I have tried the AttributeValidator transformer but it doesn’t seem to do what I want as all the records go to Failed and there’s definetly columns with all records as <Null>, see below: The ‘Attributes to Validate’ have been included the 351 columns,Any ideas how to approach this issue?Thanks :)

Hi,I am struggling to read the content of a layer published to ESRI portal. I have a  _website_urlhttps://gis-eu.xxx.com/arcgis/rest/services/LayerTest_Pt_01/FeatureServer/0for ESRI portal layer. For example I need to get Item Id HTTP_Caller does not get this info in _response_body

Hi, I have a html content in _response_body. I am struggling to get only specific text from it.

Hi, Is it possible to read all content of Esri Portal not just one group or a user?I tried to use * but it does not work 

I am new to using FME and am currently facing an issue. Here's the situation: I want to use a FeatureWriter to create a new file of type Esri Geodatabase (File Geodatabase), and I want to include the value domains of certain attributes when creating the Geodatabase. Thank you!

We have two different buffer results from the same road network and I’m doing some work on identifying what is differentThese are large multipart polygons and I wanted to chop them up to give common parts (overlay > 1) and individual parts. In the picture I want to separate the red hatched bit and the solid blue bits from  the combined data. Running the area on area overlayer with no grouping but creating a list of parts results in…Where the orange hatching has created a fill in on the closed triangle  and the roundabout. This is not what I was expecting but I cannot find a setting on the transformer to avoid this.Help!!!! ThanksRob

Hi, I cannot convert Epoch time 1717500804837 to 20241210. I have change the format using @Evaluate(@Value(_created)/1000)and run DateTimeConverter but it failed Null, empty, or missing datetime was found. Enable the passthrough parameter to disable this What am I doing wrong?

After spending all morning trying to set up a Data Stream example in FME I think I’ve got it. It’s a basic geofencing setup:I have a GPX file of one of my bike commutes and use a WebSocketConnector in a sending workspace to send one location per second to a websocket.In a second, listening, workspace, that I’m running as a Stream, I’m using a WebSocketConnector to listen to that websocket and compare the locations coming out of that with a polygon. If it falls inside the polygon I then use a HTTPCaller to send me a message via Whatsapp.This is working fine:However, some of the documentation / tutorials I found, such as Websockets and FME Server, seem to imply that

UPDATE 06/01/25:  It does indeed appear that once created, the index is automatically rebuilt on writing to the GDB with truncate existing.Steps to recreate:Add SQL statement to create attribute index after writeCREATE INDEX <name_INDEX> ON <table_name> (<attribute_name>)Run the writer either to create new GDB or update existing GDB Remove SQL statement Continue to run writer as normal going forwards-----------------------------Hi all,This is driving me crazy trying to figure out. I have a GDB writer that builds an attribute index after write.CREATE INDEX <name_INDEX> ON <table_name> (<attribute_name>)Unbeknownst to me, each time I updated the data, an additional index was being created instead of overwritten which led to a bloated GDB and blown out write times.
