I am new to this and learning but...I have a JSON object and am trying to extract the attributes to load to PostGreSQL and I am hitting my head against a wall. The format of the JSON is generally as so: {    model: 1,    version: 2,    content: [        {            x=1,            y=2        },{            x=3,            y=4        }    ]} I want to output something along the lines of:model, version,   x,    y1,            2,                1,   21,            2,                3,   4 For the life of ne I cannot work it out, to me the documentation and step by steps are not clear. I am using a standard JSON reader. Whatever I try, flattener, fragmentation, I cannot opreate on the content.I had an instance where I managed to get all extracted using an extractor but this would populate the attributes for each item in the content array and concat together to look like this:model, version,   x,    y11,            22,          13,  24 The real JSON is a lot more complicated but at this ve

I have CSVs with over 2 million rows. For some reasons, Reader appears to be dropping some columns , and yet I know Reader recognised they existed because they are missing in the column name order. For example, when columns col3 and col6 are dropped the auto-generated attribute names are col0, col0,col1,col2,col4,col5,col7,col8,col9. I have tried various options in reader but clearly not the right one . There is plenty of RAM and disk space. In some files, the missing columns are blank but I have also seen this happen in files that do not have blanks in missing columns. Some columns have strings enclosed in double-quotes. Any pointers please

I have a bunch of point data (pavement rut) along roads, that I want to practice to cluster analysis. The point of the analysis would be to show where the most significant pavement rutes are accumulated along a road section. (ex. road juction with traffic ligths )I am looking for the best FMEtransformer that can perform the analysis. Do you have any idea for it? 

Hi! Is it possible to convert png to eps in FME? If yes, how? I've tried a simple conversion with just a png reader and a eps writer, but get the error "EPS writer: EPS WRITER: Error, the feature does not have a eps type attached".

Good morningI have a problem I currently am unable to resolve, which is a csv file containing address data and additional spatial and non-spatial information related to the individual addresses. The csv file is ordered according to a Record Identifier.However each Record Identifier has a different number of columns populated with data. The minimum number of columns is 19, the maximum 29If i attach a Tester to set the 1st column to a particular Record Identifier eg 23 then attach an Inspector, the result always shows 19 columns, which is the number of columns the first record in the file has (which is Record Identifier 11).If i export to an .xlsx file using a template of the source Record Identifier data i want to write to, only the first 19 columns are populated, the other 10 columns are blank even if that particular Record Identifier uses the additional 10 columns.Can anyone suggest how i can force the tester to recognise the number of columns the Record Identifier has, or an alternat

I have a NetCDF with below values in each band. How do I go about extracting these values to an attribute using a set of points? They don't seem to come up in attribute list only when I click on a pixel in inspector.  

Hi everyone,It's Mark here with all the FME news that I can find for this week. FME Data Express v1.4.0The latest version of the FME Data Express app is now available. Apart from the usual bug fixes (we try not to include any, but they will sneak in) there is also better geometry parameter support, the location picker now remembers zoom levels and map types, and there is new search functionality in the repository list. As always you can find it on both the Apple App Store and the Google Play Store, so give it a try. It's a great way to run workspaces on Server from a mobile device. FME Server Microsoft .NET APII'm told that the Microsoft .NET API for FME Server is going to be deprecated and removed from the product for FME Server 2021. The technical reason is that the .NET API is incompatible with new updates to Server, and the work to bring it up to speed can't be justified. So, if you're using this API, we strongly recommend that you take the steps to transition t

We have a shared web and database connections directory, into which public FME connections go. Our service account that runs overnight tasks (via Windows Server 2016 task scheduler) has explicit permissions to this directory, but cannot see/use connections unless they are embedded in workspaces. Interactive login is disabled for this account, but I'm wondering if I might need to log in as the account and set default paths for FME so it can see the connections? Alternatively, any other ideas for why this may not be working? In the current case the connection is to ArcGIS Online and there is no apparent option to embed the connection in the workspace. The connection was made public as it was created.

I have some questions about working with point clouds.I’ve done a little work with them before in FME. Mostly coordinate reprojections, clipping, thinning, etc. Pretty basic stuff.This time I have a slightly more complicated problem. I have an LAS data set that is not fully classified, there are no vegetation classifications.I would like to use the LiDAR data to do some basic vegetation classification, resulting in shapefiles that I can use to classify areas that are vegetated.As someone pretty inexperienced with FME, I’m not sure what the best sort of workbench is. I would love to see some examples and to experiment a bit with both of these problems.I’ve built a few workflows but they don’t work!

Hi. I am using the Aggregator transformer to summarise some tabular data by a reference (there may be multiple records originally for each reference). I am merging the attributes and concatenating some attributes. This is technically doing exactly what I want but with nearly 1m records, it is very slow. I know there are usually multiple ways to achieve something in FME so I wondered there an alternative to the Aggregator to do what I need? Many thanks Thanks

Inserting a KMl into FME desktop results in a schema-less reader. Which steps do I have to take to convert its attribute (values) to e.g. shapefile or fgdb?

I have a FME 2019 Desktop workflow that reads three CSV files and write all input data (points) to only one FeatureClass in the output fileGeodatabase. Every CSV file has a different schema, i.e.: every CSV file has several fields in common but most of them are different. This is the workflow:Every month I will have to run this workflow with a different set of CSV files with probably will have different schema than this ones, and also could be more than three CSV files. So, how can I read automatically the schema of CSV files ? Thank you ! 

Dear FME community. I'm trying to extract, from a json object, the json arrays.My object looks like :As you can see, I've multiple sub objects and I want to extract this parts :In this case, I tried to use the transformer jsontemplater but I was stopped by the loop in the json for sub sub object.In this part I do this :But maybe it' not the best method, that's why I need help.Do you see how can I do this ?Thank you very much.

I think I read entire forum... but can't find any answer.I have number of single control point, ascii with XY column and corresponding another file containing also XY. I would like to 1stfor each control points from set 1 find a closest point from set 2 and calculate average xy and rmscombine the rms and average magnited and output as a one number Maaaasive thanks for all your timej

I'm trying to export feature layers from ArcGIS Online to Geodatabase, then upload the Geodatabase to Google Drive. I'm using a 'Choice with Alias (multiple)' user parameter to select and export one or more feature layers. If I select one feature layer my FME script works fine. If I select more than one layer then I get a geodatabase lock error while uploading the Geodatabase to Google Drive. This is the error message: PermissionError: [Errno 13] Permission denied: 'C:\\\\MyDirectory\\\\MyGeodatabase.gdb\\\\_gdb.JD2344.18360.9116.sr.lock'Error encountered while calling method `input'GoogleDrive_Geo_CALLER (PythonFactory): PythonFactory failed to process feature  I'm hoping someone can suggest a solution. My FME script is attached.Regards, Damian

Is it possible to add the coordinates from the coordinate extractor transformer to a writer? Like example from coordinate extractor column _indices{}.x (64 bit real) into a shapefile with column x. I tried changing data type from double, float, char... but the line connecting the transformer to writer simply will not connect to each other.

Im getting error while converting dxf to geojson through cmd.Cannot create dataset: 'C:\\conversions\\17d5313d-7982-45fb-98c3-a04a0e4a9b92\\tuscs.json' of type Directory, expected a dataset of type Regular filebut when i changed the path C:\\conversions\\tuscs.json translation is successful.How can i avoid this error.

Hello, I have a table like this:ID - value x - value y1 - 5 - 302 - 9 - 403 - 8 - 704 - 76 - 89I want to replace the value x of ID 4 by the value x of ID 1. So that my table would be like this:ID - value x - value y1 - 5 - 302 - 9 - 403 - 8- 704 - 5 - 89What transformer should I use ?

Hi, I currently administer an ArcSDE database and have most things automated with Python and task scheduling. This works well but it is far from transparent and simple, and I feel I could use FME to automate the entire process. I'm thinking that while some of the process could be handled with the inbuilt transformers I would definitely still need to utilise ArcPy for most tasks and so would rely heavily on the PythonCaller transformer.  Is this an avenue I should explore, or is this best dealt with another way? Has any one else successfully done this, and if so are there any examples available? Thanks in advance. Nathan

I am missing the chopped indicator attribute under the parameters for transformer chopper, why is that? and instead I get parameter aggregate or reject,

I have a workflow, using FME, that outputs an annotation layer in a file geodatabase.At first I create some pre-defined Annotation Classes in an empty geodatabase that will be used to style Water and Road text features etc. I note down the AnnotationClassID of each class.I then run the workflow which assigns the AnnotationClassID noted earlier to each feature based on a feature class attribute from the source data. This workflow also sets the FontSize, Rotation and Vertical and Horizontal Alignments of the Annotation feature.This runs fine and I can see the results in ArcMap as expected. However, I was wondering if it is possible to tweak the styles of this output Annotation layer?When I try editing one feature and changing its AnnotationClassID, called "SymbolID" in the attribute table, from a Water to a Road text style of the pre-defined Annotation Classes, the FontSize automatically reduces from a large number, 93543 (set from the workflow above), to 8, drastically reducin

Hi I need to calculate the angle between lines in a network (red angle in the picture) I mean the angle between the side road and the main road ThxFrancesco

Hi I would like to make boundries around my pointclouds.That way I can see if all my pointclouds cover an area.  I only know hullaccumulator, but that only makes a bounding box. See the picture below. I want the red boundry and not the blue one that hullaccumulator makes.I'm trying the pointcloudcoerser before the hullaccumulator, but I don't know if that works and it takes sooooo looong... Is there a better way? 

I have a problem with setting up an ordered attribute list in a published paramter. I haven't found a hint in any documentation, how to type in the list in the "edit configuration" window. Is there any documentation I did not find or does it follow the semantics of a language, like e.g. python?
