FME Form

I want to find the biggest possible box inside an area, like the opposite of a bounding box. It should also be oriented.

 I want to define the location of my log file, and tried to set the path together in a File/Url type user parameter. One part of the name can contain letters e.g. ø, å, æ etc and I can see in the translation log they are returned as utf8 codecs (e.g. _00f8_).In earlier versions of FME Desktop was there the possibility to specifiy the character encoding, but it seems like somebody forgot to implement this in 2021.The definition of the path should be as such: C:Temp\$(WORKSPACE_NAME)_$(b_number)_$(municipality)_$(year).log, where 'municipality' can contain special characters. The other thing is of course, that as soon as $(WORKSPACE_NAME) is in the picture i am getting 'Undefined macro `WORKSPACE_NAME' dereferenced in file'. Last problem the log file does of course not exist at the point when I start the workspace. Do I have to create the logfile manually i a startup script?

I'm having trouble getting a dwg writer to write multiple files. What is syntax in FME desktop v. 2019.0 If I write .... *. Dwg - then there are errors - probably because it writes all dgn files to the same dwg file - If I do not write anything there are also errors.

I am looking for a sumproduct like function in excel that i can use on data i have in FME. What i am really after is a weighted average of certain groups of data. I have the products solved for in separate fields but i can't sum within their groups.

i would like to use OSM Openstreemap , i have downloaded BPF for a city from Geofabrik Download server ,is that the correct extension or which extension should i download ?  could someone provide me with an example for OSM Workspace ?and what shoud i do ? i would like to show output geographical map for polygon as Google maps . FME 2018Thanks in advance

I am trying to split an attribute using a regular expression as there may be differences within the attribute. For Example the attribute may be as AA9A or B7BHowever some of the attributes are formatted as CC7 or DD6 I therefore do not want to remove the last character from these, all I need to extract is AA9 or B7. Is there a way with a regular expression to search for a character, potential character and then a digit?Or is there a better way to achieve what i am trying to do??Thanks in advanceAndy  

The aim is to use the current transformers that FME has to offer. Any help with this is much appreciated. Thanks,Sam

Good day!  I am having difficulties getting FME to use Oracle readers and writers. I am using 64bit for both FME and Oracle instant client.  From the website, I followed the instructions for downloading an Oracle Instant Client, unzipping it to a directory and adding this to the front of my PATH environment. The options in the reader and writer gallery are still greyed-out however. I have been trawling the web for the past day or so and nothing I see helps (or makes sense to me!).   Any help would be appreciated   Rich L   

Hi All,I created a SchemaMapper lookup table in PostgreSQL and used it to map schemas in two scenarios.When I used ESRI SDE feature class as a reader and PostgreSQL as a writer the SchemaMapper mapped all and no problemWhen I used SQLExecutor reading from Microsoft SQL Server database that creates a query from four tables and writing to a Single PostgreSQL table, the SchemaMapper outputs the results as unmapped. I have used AttributeExposer transformer and it still didn't change. please see the screen shot below:Can anyone please help me fix the issue or let me know if I'm missing anything?Thank you in advance

Hello, I am currently exploring the capabilities of FME Server and I am trying to do a web map application that show the latest earthquakes using the USGS API: https://earthquake.usgs.gov/fdsnws/event/1/ I have already set up a workspace that gets the information and organize it spatially, so I may think that the next step is to publish that workspace to FME Server and schedule a job every minute or something (for example)  but now to visualize that changes in a web interface I have think that I will need send a JSON using a websocket sender transformer and configure my web app to get that websocket and utilize it to display the location of the earthquake? What do you think about that workflow? Do you ever try to do something similar? Please point me out in the right direction. Thanks.

Hello to the community!I'm new to the FME and I'm quite impressed with what it can do and also with the very helpful tips and solutions which I read in this forum! As a newbee, I'm struggling to get the result which I want, but for most of the experts here, it's probably quite simple: I'm working with polygons which represent the chart coverages of Electrionic Navigational Charts. They are categorized into "usages" with usage 6 having the largest scale (inside harbours) and usage 1 having the smallest scale (covering entire oceans). The set of polygons is currently overlapping each other and my goal is to have a non-overlapping set of polygons - perfectly touching each other's boundaries - which give me the best chart usage at any given point. I have already created a workflow where I dissolved usages 2 to 6 and then used the Clipper to clip usage 1 with this. Similarly, I dissolved usage 3 to 6 and clipped usage 2 with it - and so forth. Doing it thi

i have cut specific image with clipper but when i use clipper inside ,i found it includes my target and also black parts around the image that i need to have .how could i cancel black parts ,and keep only my target image ?

I used the Directory and File Pathnames reader to go through folders and select all shapefiles. Then trying to use GeometryExtractor and GeometryFilter to filter line shapefiles but GeometryExtractor output has no geometry. Then I'm using the GeometryReplacer to replace the geometry but again the output has no geometry and the GeometryFilter cannot filter lines.I'm very new to FME so please go easy!Thanks in advance.

I have a bunch of line pairs where each individual line has been assigned a UUID and is stored in a list: UUID_PARTS{} with indices 0 and 1.  Also have some aggregates of three which contain the same lines as the pairs, plus an additional line. They also have the same list attribute, where the indices are 0, 1, 2. The pairs and trios of lines are currently separated, but could be combined if needed. Have tried both list-based feature merger and regular feature merger on UUID_PARTS{0} or UUID_PARTS{1} with various settings, but no luck. My goal is for this to be flexible enough so it does not matter what index the matching UUIDs are and also handle aggregates with more than three parts, if possible. Any ideas? Thanks, @larue

I would like to use the PIL module to resize an image stored in a blob (geodatabase attachment table) but I cannot create the Image object from the string representation in the pythonCaller This is what I have tried so far:import fme, fmeobjectsfrom PIL import Imagefrom io import StringIO def processFeature(feature):  string_io = StringIO(feature.getAttribute("data"))  img = Image.open(string_io) #here I have the following error: Python Exception <OSError>: cannot identify image file <_io.StringIO object at 0x0000000007CE4438>   img = img.resize((1000, int(round((width / float(img.size[0])) * img.size[1]))), Image.ANTIALIAS) I have the following error Python Exception <OSError>: cannot identify image file <_io.StringIO object at 0x0000000007CE4438>

Hey FME'ers,I just posted a video of how to create tooltips in an HTML report:https://youtu.be/O6gT58AnvuA Basically, I create an HTML table and one of the cells takes up too much space for reasonable viewing; so I turn its content into a tooltip to save space. The important part is the code, which you can't get from the video, so here it is. The content of the cell is created with an AttributeManager as:<span>Hover for more info!</span><div>@Value(attributeName)</div>Then there is some custom HTML to add to the top of the report. Use a Custom HTML option in the HTMLReportGenerator with this code:<style>div {  background-color: yellow;  padding: 20px;  display: none;  position:fixed;  top:80px;  right: 350px;}  span:hover + div {  display: block;}</style>Now your content will appear in a tooltip, rather than a table cell. I hope this is useful. Watch the video if you need more details about where to place the above code.

Hello Community, I am trying to extract values of attributes in a table that is in a HTML page.Actually the table is updated every 20 minutes or so on this URL:  https://www.hydrodaten.admin.ch/fr/2174.html The table looks like this:I have tried to use a HTML Table reader but unfortunately the attributes names contain also a date / time and they are changing all the time, so if I extract it at regular intervals, it doesnt work anymore as the field name will have changed in between:  Then I have tried the Http Caller + HTML Extractor but I can't figure out which CSS Selector I should use to extract the values of the table. Here is the HTML part of the webpage that contains the information I am looking for: <div class="horizontal-scroll-wrapper"> <table class="table table-bordered table-narrow">  <thead>  <tr>   <th width="30%" scope="col">Mesures</th>    <th class="text-center" scope="col&q

Hello,  i have question and problem with ShapeFile Reader.I have a lot of data with Numeric field N,12,6 (location_x, location_y, location_z). But separator is set with "," not "."FME is cutting my data.  Can somebody help mi with this issue? In previous version was parameter "Numeric Attribute Type Handling" but for now it's not accessable. QGiS is correctly reading numeric values. 

i have OSM (Openstreetmaps) in shape file and i have found at inspector that it has no color so i would like to color it and get cartographic output that includes suitable color for the map .but i am new in Fme and i am not sure which parmeter should i define at MAPnikRastersizer transformer .is there any method to download the map from openstreetmap ,including the suitable color as Google maps . also i would like to know ,how could i extract specific polygon from lots of polygons in OSM .FME 2018 Thanks in advance

Hi!In a project, I want to plot the bounding points of an area onto a map. To do that I am mainly using the Featurereader to grab the map from a WMS using said bounding points (as a polygon). In order to do this to grab the map, I need to change the coordinate system. Thats why I'm using a Reprojector to convert from the national coordinate system SWEREF991800 to EPSG:4326, which is the proper one for the WMS.The operation kind of works, I manage to grab the map including my bounding points, and I can confirm it is the correct area. However, the reprojected points and the WSM appear scaled in the X-axis, instead of being almost a square. Please see the attached pictures. Why am I seeing this, is it a Reprojection problem?

How to do when I want to create roof shape from dsm data (tiff image) and outline2D(shapefile)?I can only do LOD1. I want to know if I can use data such as slope to create LOD2?

I have 2 shapefile files, each have about 13,000 features. I need to know what the minimum and maximum distance each feature of file 1 for example has in relation to file 2. How to do that?

I am using the Amazon s3 bucket modified listener to trigger a workspace and process data as soon as it enters our bucket. Some days ago we had to change the region settings and since then i am getting this error:2021-07-12T10:32:29Z | An error occurred: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'us-east-2' (Service: Amazon S3; Status Code: 400; Error Code: AuthorizationHeaderMalformed; Request ID: ********; S3 Extended Request ID: *****)The FME server version is 2020.1.3.2, i don't have access to the config files of the server. Is it possible to set the region of the listener manually somehow or a trick to solve the problem? I tried same connection on another instance of the FME server and i had no problems there.
