StatisticsCalculator bug?

It seems that StatisticsCalculator doesn´t work well when I group features by numeric (only numbers: [0-9]+) field keys. I attach a sample.

statistic calculator issue

Hi,i have an issue with the statistic calculator, doing some IDW Interpolation.I use a counter (the only one within the workbench) to create an id, called "_zaehler". Later on I use this attribute as a group by attribute in the statistic calculator. The point is that, with the illustrated settings (count start=3000), I loose some points (with theses settings 530 points!). The missing points look like this:If I set the count start to, say 10.000, all points are processed! This behaviour is unclear to me!

Generalise Points - Convert Multiple Points to Single Points based on proximity and attributes.

Hello, I have a point shapefile containing every aeronautical obstruction in the UK above 80ft. I am working with Largescale mapping and need to generalise the points so as not to clutter the chart. I need to merge multiple points into single points based on their proximity to each other and other attributes. Then create a new attribute stating that the new point is now a 'Multipoint'. Additionally I will need to retain the metadata of the highest obstruction of the generalised points.Thank you very much in advance for any assistance you can provide.@1spatialdave

Spatial filters and conditions

I have a set of lines, and a set of polygons. I've used a spatial filter to check wether or not the lines intersect with the polygons. I want to filter the polygons that don't have an intersecting line. The lines were used as filter, and the polygons as candidate. That worked fine.However, I wanted to add a condition that only intersections of more than a specified number should be considered valid intersections. Seems pretty straightforward, but I don't get any output once I set a conditionThis is my workbench. Reader 1 are the lines, reader 2 the polygons. To set the condition, I select "intersect" as tests to perform in the spatial filter. After that I click the drop down menu for that tests and select/type the condition: if length <= 1I think I'm forgetting something really small, but I just can't seem to figure out what.

Processing of big rasters.

I have a lot of orthophotomaps in tiff format. The size of all files is about 900GB. I want to join all files to one. Next I want to change coordinate system and next I want to intersect the orthophoto using appropriate frames. I have problem because FME doesn't operate so big raster. Could You give me advice how can I do it?

Creating a SchemaFeature and mapping values to it

Hi I have managed to create new attributes for a SchemaFeature: And when I set the Excel Writer Schema Sources to "Schema From Schema Feature" I am outputting an excel spreadsheet with the new column headers as I require. However, I can't work out how to populate these column headers! I tried to populate them in AttributeManager like so: But then in the excel spreadsheet the values of the column headers replaced the column headers themselves. I seem to be missing one vital step here but I can't work out what it is. Thanks,

Leading and Trailing Zeros being Stripped off

I have a number of columns that contain data that can have the following values (0.25, 0.5, 0.75, 1.0, 2.0, 3.0 and 4.0) These are the only acceptable values but the leading and trailing zeros are being stripped off when the data runs through the FME script. How can I ensure that this does not happen?

Python Raster API - Unable to create a RED8 band

I have been struggling with this issue for two days. In summary, I am reading in some locations with the intent of creating mapping tiles only for those locations (the territory I am covering is huge, so an overall raster + raster tiler is not an option). The flow of the workspace is as follows:Read the "Sample.csv" Calculate the tile boundaries and tiles index numbers based in the PyTileMaker scriptSort the tiles so that similar tiles are grouped (in TileSorter)Generate the tiles bands, raster and points-in-tile in PyMakePointsIn the last step, I need to produce 4 bands (as in RGBA). The raster and bands are 256x256. I can generate the 4 bands if I use FME_INTERPRETATION_UINT8 for the band properties and a UInt8BandTilePopulator to generate the band. Unfortunately, the resulting raster has no idea which band is which in terms of RGB or alpha.So it seems logical that one would generate bands with the proper interpretation property, such as FME_INTERPRETATION_RED8 and a band p

How do I set a parameter value to contain a list of files when running workspace using runner.runWithParameters

I am wanting to translate a list of files in a directory from one raster format to another by calling an FME workspace using the Python fmeobjects API.import osimport syssys.path.append(r'C:\Program Files\FME\fmeobjects\python27')import fmeobjectsworkbench = r'D:\ESRIGrid2GeoTiff.fmw'directory = r'D:\Test\A Folder'raster_files = [os.path.join(directory, raster) for raster in os.listdir(directory) if raster.endswith('.asc')]parameters = {'SourceDataset': '\"' + '\" \"'.join(raster_files) + '\"', 'DestinationFolder': directory, 'InputCoordinateSystem': 'MGA94-54'}fme_runner = fmeobjects.FMEWorkspaceRunner()fme_runner.runWithParameters(workbench, parameters)From the log file its seems the issue is that the FME reader splits the paths where there is a space in a folder/file name, even though each path should be enclosed in double quotation marks.

scale by group id

I have a group of features that are merged together into a spatial boundary (buffer of 25 feet) and I'd like to scale each group of features (lines included) from a known center point to a scale that would make each group more readable with labels. The number of groups varies from map to map. Each group is created as an inset map to a PDF. The brown diamond is where the center point is and the anchor point for my scaler. I wonder why the scaler transformer doesn't have a group by.

How to write XML metadata to Esri Geodatabase (ArcSDE Geodb Raster Dataset)?

For a project I’m trying to use FME to directly write XML formatted metadata, stored in an attribute, to an ArcSDE Oracle database with FME. Following these examples (1&2), It works fine with a SDE Feature Class & the Esri Geodatabase (ArcSDE Geodb) writer. However, for a SDE Raster Dataset I’m experiencing some difficulties: The Esri Geodatabase (ArcSDE Geodb) writer won’t let me write to SDE Raster Dataset The Esri Geodatabase (ArcSDE Geodb Raster Dataset) writer doesn’t have the option to set the allowed geometries to geodb_metadata.Does anybody have experience with this issue (and perhaps a solution), or am I doing something wrong?

Control feature append order

Hi,I have a workspace with two creators which I use to create a single constant text line each. The rest of the workflow reads data and creates text lines depending on the content of the data (10 lines in this example). Now I want to write the text line of the first creator first to a text file, then the lines generated dependent on the data and the text line from creator_2 last. As Creator_2 is much faster then reading all the data in between, in the resulting text file I get the text line from Creator_1 first, then the line from Creator_2 and the lines from the data last. Is there a way to control that the line created by Creator_2 is written last?So far I can only see that the Creator order can be controlled...thanks,Ludwig

FME Equivalent of Microstation Move, Rotate and Scale

I am trying to automate one of our processes here, where we import a LandXML file in, then move, rotate and scale to match up to our DCDB. I've got workbenches setup to define how much move, rotate and scale is needed, but what I need to do, is create a control point that won't move, rotate or scale, but the rest of the data to move, rotate and scale around this accurate mark. How do I define this mark as an anchored point?Once I define this, I'll then ask about how to do these adjustments?
