Artiificially creating polygons

Hello Forum, Is it possible to artificially create a polygon based on the lower edge of an existing polygon? Imagine I have an existing polygon, I’d then want to create a new polygon that snaps to the lower edge of the existing polygon. The depth of that polygon doesn’t matter, for example it could just be roughly 50 metres away from the shared boundary. What really matters is that is snaps to the lower edge of the existing polygon. An alternative approach could be that the artificially created polygon is a doughnut polygon which wraps around the existing polygon to say, a depth of 50 metres. I could then split it manually where required… I hope this makes sense. Any ideas? Thanks,Stuart

FME vs Python in GIS editable feature layer and Microsoft Word Template Table

Hi folks!I am torn as to what workflow to use between FME and python. I am more comfortable with FME so hopefully FME would be the winner here.The workflow I am trying to achieve for the business user is to have a GIS editable feature layer containing field summaries translate into a docx with a table template (ideally with the same attributes as the GIS feature layer).A sample of the table template in the docx is below:Any time a new field summary project gets entered into the GIS editable feature layer, ideally, a net new Word document with a separate table with populated values from the GIS editable feature layer will populate in the corresponding values in the table within the docx. Any updates that are made to existing field work project records within the GIS editable feature layer would have the updated records/values also translate into the associated Word Document with table template values as well.So in the above, the values from the project name, date, crew, permits, divisio

Issue when adding Writer

Before I updated to Form 2024.1.2.0, when I added a writer it would automatically name the Feature/Table and assign the geometry type. Also, if there were multiple readers in the workspace the add writer function would prompt to select individual or all feature/table names associated with the readers. Now the writers have to be individually added, named, and assigned a geometry type. This can be very tedious and time prohibitive in many cases (which goes against all things FME). Is there a default setting that I’m missing?

Reading API and extracting geometry

Hi, I am retrieving data through an API using an HTTP caller. The data consists of points and lines. My plan is to pull this data, perform some attribute mapping, and then POST it to a website. However, I'm having trouble extracting geometry after flattening the JSON data. I used a Geometry Replacer, but it fails every time I run it. The error message says:INVALID_PARAMETER_GEOMETRY_SOURCEI would appreciate any assistance with this!

create non-intersecting polygons from multiple points based on attribute value sum

Hi,I have a file of points which correspond to buildings. Each point or building has a number of apartments (total 9000). from this layer, I would like to create zones for every 500 apartments, without intersection. I tried the neighbor finder with sorter assending on the distance then range mapper attributes but the result is not good because I should not have any intersection between the polygons. Help please :) Thanks a lot

MULTI_WRITER was not specified error: Why do I need it? How do I resolve?

I'd like to understand what this error means in the following context and how I might go about resolving it. I have a workspace that works perfectly fine if I run using cached features up to transformers just prior to a FeatureMerger then run from the FeatureMerger to a writer. However, when I try to run the entire workspace it results in an error that aborts the translation at the writer. I've also tried many other methods of joining these 2 streams and all are resulting in the same error output. MULTI_WRITER: No MULTI_WRITER_TYPE{*} or MULTI_WRITER_TYPE{3} was specifiedIt seems like I need both streams to be ready at the FeatureMerger at the same time but I have not been able to gain control over execution order or block passthrough features through a variety of attempts. The goal is to read from both a CAD model and a DB, then compare the two datasets on a unique key, then write an SQL statement to a text file or SQLExecutor. I've only attempted this with the text file writer while

Inconsistencies when reading File Geodatabase with a FeatureReader

Hello,I am experiencing some odd behaviour with the FeatureReader when trying to read in a schema from a Feature Class in a FGDB. I am using the “path_windows” attribute that contains the location of the gdb. When run like this, I often get a rejected message (see Caption 2). When I add in the hard coded full path into the Dataset field of the FeatureReader, the data gets read correctly. What is strange is that this has been working fine in the previous weeks when I had developed it. It only appears to be an issue since today. It also seems to read successfully when I run the workbench with caching to the Aggregator before the Feature Reader, then running again from the aggregator (no settings have been changed). I have tried using the path_unix field instead, but get the same error. I have also tried other datasets, but get the same issue.Has anyone experienced similar behaviour when using the FeatureReader with a GDB?… and any ideas to help with the stability of the run?

Running workspace with "ignore failed readers" on gives error

Hi all, i've got a strage error. I have about 30 ArcGIS Online readers that i want to read, update and write back to ArcGIS Online. Now, the update part with the Changedetector workes fine. (Dont look at the mess ;). The problem:When i run the workspace, it gets all the 41K features that are in there. The other ones are skipped because it is not found. This works as it should work. After that it tries to search in groups accessible to the user, and then it says "error running translation”. Does anyone know how to fix this? I have attached the log file and the workspace. Thanks in advance!

Sloping beach volume calcualtion

I want to calculate it above a horizontal plane at a level input as a user parameter and I have individually references mif/mid polygons demarking the areas.I have been using the method at the below link as a starting point, but the problem is the beach is sloping, not flat, meaning using the z.median value gives an incorrect result.https://support.safe.com/hc/en-us/articles/25407483031053-Volume-Measurements-with-the-VolumeCalculatorAny suggestions for a solution would be gratefully recieved!

Filling in holes in a polygon dataset

Hello Forum, I have a polygon dataset of railway land, but it contain holes where items such as buildings, tracks and signal boxes would be. I need to fill in these holes to form a continuous polygon. The image below shows a sample of the data. I’d want to fill in holes like those marked in red. But I do not need to close spaces such as those marked in gold. I’ve seen…. … but I don’t think that’s suitable for the task. I’ve also looked at Dissolver, but I’m not sure if that's the right way to go. Any ideas, please. Thanks,Stuart

FME Workbench and other FME Form software broken by VMWare Tools

Since updating our FME Form host computer with the latest version of VMWare Tools, FME Desktop, FME Data Inspector, and all other FME Form GUI software does not run.We briefly get a spinner and then nothing. The problem was noted on FME version 2021 but is a problem with all version of FME Form up to the latest version FME(R) 2024.1.3.0 (20240927 - Build 24627 - WIN64).It is still possible to run Workspaces in batch mode.The issue seems to be with OpenGL as indicted in the log, below.I would be interested if others have the same issue and, if so, how the issue can be resolved.Here is a snip from the log file:VMWare Tools v12.5.0.24276846Faulting Module = vm3dgl64.dllWorking Version = 3.5.3.2Faulting Version = 3.6.0.0 Event Log:Faulting application name: fmeworkbench.exe, version: 2021.7.41.21614, time stamp: 0x60f7b7a5Faulting module name: vm3dgl64.dll, version: 3.6.0.0, time stamp: 0x66a16726Exception code: 0xc0000005Fault offset: 0x0000000000e3696dFaulting process id: 0x1becFaulting

Using the WHERE Clause in a FeatureReader to search for features based on input parameters from a csv file.

I'm trying to use the WHERE Clause in a FeatureReader. I'm reading in an Oracle SDE featureclass and want to only select those records that match an attribute in a csv file I've loaded. I'm assuming that I have everything setup correctly where the attributes from the csv file are FME Feature Attributes. It seems when I add the @Value(col0) to my WHERE Clause, it breaks. How can I check to make sure it is setup correctly?

Oracle Upsert not working

Hi,I need to use Upsert to either Update or Insert features into an Oracle database.If I use Insert to add values it works a treat, so the connection to the Oracle tables is good.As the Oracle tables are large, when adding the writer I use Import from Dataset… This picks up the format of the date fields and all sorts. It works well for initially inserting the data.However, when dealing with deltas, which might be Inserts or Updates I want to use Upsert. I can test it on a filegeodatabase and it works perfectly. Taking that knowledge into the Oracle process like this: I use the NODE_ID as this is the unique identifier.However, this fails.So I have followed the guidance to implement fme_db_operation, I have created a new attribute field of that name, and used a FeatureReader, FeatureMerger, and then AttributeCreator to define whether the feature is classed as INSERT or UPDATE. All works well in the workspace, and a manual / visual comparison between Workbench and the Oracle table conclud

FME Multiwriter (generic) configuration

i was reading on FME Form Advanced module, in Generic writing sectionand it has this part that mentioned : When you use the Generic Writer, it is sometimes helpful to pre-configure parameters specific to individual output formats. For example, you must specify a seed file to write a Bentley MicroStation Design file.To do this, add a writer to a workspace. This step causes Workbench to think that there is more than one output format and forces Workbench to create a Multiwriter for the workspace. The first writer in the multi-writer will be the Generic writer, and this one should have all the output feature types. The second writer will have no feature types but will be used to communicate any format-specific writer settings to the Generic writer when FME users that format for the Generic writer.Suppose you configure the Generic writer to write to a format requiring a filename as a dataset. In that case, the Generic writer will turn the output folder into a filename by appending a file e

Alternative way to assign PrimaryKey and Serial data type

Hello,Is there any way to assign Index “Primary key” to the field and Type “serial” somehow in another way rather than in Feature writer - User attributes? These options are not present in AttributeManager transformer, unfortunately. That would help me to reduce number of manual adjustments and use “Automatic” attribute definition. Because I have many FeatureWriter transformers in my workspace and I need to replicate it to read another data.

Hold Data from filter to be able to set projection

In the above image, I read a text file that contains lines of data where specific lines that start with an ID relate to different features.In the #1 category it contains the projection information but I want to be able to set the projection of the other output ports based in the information in that line.How do I hold and set the projection of the Lines, Points, etc?I was thinking that I may just need to read the text file twice, once to get the projection from Port #1 and then have a feature reader that can then set the projection before processing the other output ports.Is there a more efficient way of doing it?

Esri Geodatabase (ArcSDE Geodb) Writer Parameters for updating metadata

Hi,I have seen a few articles about updating metadata using the ArcSDE writers, which involve writing data and adding metadata simultaneously.

I already have my metadata and types formatted as described in the articles I’ve read.xml formatted for esri importHowever, I am struggling to determine the exact settings needed for the writer. Since we don’t have a test system, I want to ensure I’m on the right track before proceeding. That said, I can create some test tables to trial the process.
