JSON MultiPolygon

I'm very new to FME and sorry if my question is stupid.There are some JSON data containing objects with multipolygon geometry on a single spline 256x256 with integer values of (x, y) as you can see in following example (just part of whole file of course) {"HotspotMetaData":{"id":162011,"RenderedGeometry":{"type":"MultiPolygon","coordinates":[[[[0,231],[-3,228],[-9,233],[-6,236],[0,231]]],[[[1,227],[-1,225],[-6,231],[-3,234],[1,227]]],[[[3,224],[0,222],[-3,228],[0,230],[3,224]]],[[[8,229],[9,225],[0,222],[-1,226],[8,229]]]]}},"hintContent":"40 km/h","unit":"kilometers per hour","description":40}See on JsonEditorOnlineAs I can see it is very similary to GeoJSON except that "Rendered ...", but! First of all FME say me "There is no geometry". Ok, I can live without it. But I see no way how to access that multi-array of coordinates. I got all of that &qu

Processing Features in Groups based on Attribute Value, e.g. using AttributeFilter

So I just got my toes wet with customer transformers and loops. Fascinating. For the first time the worlds of programming and FME seem to really come together here in my mind. Limitless potential.I put together a custom transformers that takes a bunch of point features, then identifies a certain point, pops it out into feature holder and feeds the rest of the points back to the start of the loop. Essentially, this allows me to put these points in any order I would like for further processing, using my own business logic.Now, this works great for one set of points. What if I have 10K points and would like to use my custom transformers on batches of these. I can split them out in to groups/stream using an AttributeFilter but how do I connect that to the custom transformer? I could certainly connect each stream to a copy of the transformer but that would be crude and crazy clutter. Is there something like a FeatureHolder or some other trick - some form of GroupBy - before we get to the cu

Is it possible to write ECW-Files with changed coordinate system name?

I have a raster in coordinate system EPSG:25833 (ETRS89.UTM-33N). The coordinate system is saved with name ETRS_1989_UTM_Zone_33N in GeoTIFF and Esri Shapefile, but in ECW with name NUTM33. The coordinate systems are the same, only with different name.I have viewed the properties with Esri ArcGIS. The different coordinate system names are in ArcGIS no porblem, but in the software GeODin Maps.How to do it to write coordinate system name ETRS_1989_UTM_Zone_33N into the ECW file?

I have a large dataset of geometries that are touching multiple other geometries. I would like to use the four colour theorem to isolate areas that do not touch. How can this be done in FME? Should I be using the feature colour setter?

As a note, we can do this in QGIS using the Topological colouring.

How can I create a web feature service with a geojson file?

Dear FME community,I have a question concerning the creation of a web feature service. On the following web-page (https://community.safe.com/s/article/how-to-create-a-wfs-service-using-fme-server) I have seen a tutorial on how to create a web feature service. Here a SpatiaLite-file is loaded into the workspace to create the web feature service. I have a geojson-file with some 2D geometry in it. It contains a tile-grid made out of polygons. Is it possible to either convert this geojson into a web feature service or create a new tile grid with labeled tiles? It would also be nice if one could hover over the tiles to highlight them in a different color. The whole web feature service should have a very small file-size so that the web-map does not take very long to load. Thank you so much in advance for your help! With kind regardsChristian

Can I use User Parameter value to filter dynamic selection of Attributes with AttributeKeeper?

Hi! Hope someone can help me out with this: I'm trying to create some sort of dynamic way to filter specific set of Attributes. Since the AttributeKeeper needs this input: AttributeName1,AttributeName2,AttributeName3,etc input, I was wandering if I can use a AttriubuteValue for this..but this is where I got lost;) I've created an attribute with concatenated list of Attributes I want to keep. But what would be a good approche to use this value to keep specific set of Attributes? cheers,ronald

Transforming bulk Excel files to PDFs

Hi all, I feel like I'm asking a well-trod question, but I'm having trouble with blank PDFs being output and am going a bit mad with the PDFStyler, PDFPageFormatter and TableAdder. Basically, I need to create multiple PDFs, grouped by username, from input Excel files. So far, with very little luck, other than the fanout naming (of these usernames). With the TableAdder I end up getting everything squashed into blocks of unreadable text, despite trying different values. I wasn't sure if I was missing anything obvious, or if there was an easier way to start this process. Thanks

Problems with Chopper when trying to chop by length

I have a line that I try to divide in smaller parts of 5 m each. The line is is from a shapefile. When I try to use the chopper it divides the line in random parts, varying in length from 7 to 113 meter, but in not a single case in 5 meter. Am I doing something wrong or is this a bug in the transformer?Hope someone can help.

When FME writes data into MS ACCESS file and there are date fields, it fails when the date value is from before 30.12.1899. Is it because of the native definition of a date values in Access? Any ideas or similar observations?

Access stores the Date/Time data type as a double-precision, floating-point number up to 15 decimal places. It stores dates before December 30, 1899 as negative numbers...Is it the conversion issue from FME date definition to Access definition? Seems like it only supports positive numbers (later than 30.12.1899)?

Is it possible to update a feature class in a fgdb with a dynamic writer?

I have a dynamic workspace with a dynamic file geodatabase reader. I want to update some of the feature classes in the file geodatabase. When I use a normal (=not dynamic) writer, it works. However, I would like to use a dynamic writer. But with the dynamic writer, I always get an error: "Geodatabase Writer: Feature Class or Table 'd_y_n' must exist when Table Handling is set to 'Use Existing'" - I don't know where the 'd_y_n' comes from. What am I doing wrong?
