How to read live data streams in text files

I am wondering if anyone have any suggestions to use FME to process live data streams that are funneled into various text files, server log files being one of the examples. Thanks!

What is the FME equivalent of the ArcGIS Minimum Bounding Geometry tool?

I have intersecting lines that I wish to transform into a polygon. The resulting polygon should trace the exterior vertices and "hug" the original lines. I've heard of a Minimum Bounding Geometry tool before, but can't find this in FME. The bufferer won't work. How do I create my polygon?

Why is my simple clipping workbench not working?

Workbench:reader1: ECW --> RasterSelector (3 ALL) --> RasterBandRemover -->Clipper --> writer:JPGreader2: SHP -->After starting it I get this: LOGIt just stops until I manually stop it. I use FME 2017.1.0.0.The strange thing is that when I make the same workbench on a colleagues computer (FME 2017 1.2.1) It runs with no problems and makes the JPG in 1 min.

Identify overlapping areas in a single source data

Hi,I would like to identify overlaps but only from a single source of data. That data has 1500+ records of unique Region Name. However, I found an instance where a part of a region is overlapping another adjacent region. I would like to identify how many instances I have in my database identifying at least 1 region name and creating an area of the overlapped.as shown below, green area has a portion of the adjacent boundary.any help is appreciated. thanksLex

Extracting slope values from contour lines to polyline network

Hi there,  I'm working on a project where I'm trying to identify the slope of various segments along a pedestrian network based on contour lines. The ultimate goal is to create a dataset that shows changes in slope along various portions of the pedestrian network (say every 3 feet).I'm new to working with contour lines, and I was wondering whether anyone has initial suggestions on how to approach this project in FME?cc'ing @takashi since I've found your explanations very helpful in the past.

calculate running total based on variable time grouping

i am new to FME and i am trying to find a way to calculate a running total for a large set of gauge data. I have a point with 24 hours of data, and i would like to sum a running total based on: 3 hours; 6 hours; 9 hours, 12 hours, etc.... for each point. i tried the statistics calculator but that gave me a running total of all the records. i would like them group by 3's, 6's, 12's, etc. any assistance would be appreciated.

FME Server 2017.1.1.1 Dashboard being emptied by itself

I have a strange issue where Dashboard seems to run (ran it manually) and within a couple of seconds, it is empty. Needless to say, no history is available, either....Cleanup is running things with a longevity of 1 week, so I assume that cannot be the issue....Anybody experienced this before ? This worked fine before in 2017.1.1

Split chain at point intersect

Hi, I have two readers where one is a line object and the other is a point object. Sometimes, my point objects will lie on the line or it may be at the end of a line. In the case that it is on the line, I want to split the line and be able to produce two lines. Please advise. Thank you very much!

Detect direction of slope from contour lines

I am trying to build height labels for contour lines from the lines themselves. This is pretty straightforward since the height values are contained in the contour data and I can easily extract them with the Labeller. The problem is that I want all the height labels to be rotated as if one was always reading them facing uphill. They currently come out of the Labeller facing both uphill and downhill. The labels follow the contour line as they should, all that is fine, my only issue is that I want to rotate some of them 180 degrees. How can I use the neighbouring contour lines to detect what is uphill? What is the best way to rotate the eronous labels based on the above direction?

Is it possible to extract numbers from the FME log whilst running the translation

I've got a workbench set up with a SystemCaller to run my saved SQL query in PostGIS - using one table with unique IDs (let's call it "delete table") to remove records from 6 other tables in my PostGIS database based on the same IDs. I then want to double check whether the query was successful and compare it to the number of records in the "delete table" before moving on to the next stage of the workbench. I can see the log displaying how many records were deleted off each table as it's showing it as 'DELETE 67' etc whilst running the query. Would it be possible to extract those numbers from the log and use it further in my workbench in e.g. TestFilter to check whether everything in the "delete table" has actually been deleted before moving on to the next stage of the workbench?

Aggregate geometry of non-touching polygons and keep attributes of each

Hello everyone !I have this problem since a couple of days... I want to aggregate the geometry of several non-touching polygons based on a common attribute (the id of the administrative area they are part of) but I also need to keep the other attributes of each polygon. I thought the Aggregator was the designed tool for that but I can't find out how to keep attributes of each part of the resulting "multipolygon". I always loose information of the individual polygons...Thanks for your help ! ps: please forgive my english as it's not my mother tongue.

Matrix of all unique values per attribute field of a dataset

Hi,I have a new source with poor metadata. I would like to create a quick overview of the dataset by producing a matrix, where I have each attribute field and all unique values within that field listed. With aggregator or duplicate filter I can easily do one. But I have close to 100 fields, so there must be a more clever way...Thanks for any suggestions!

Htmlreportgenerator charts inside infobox

Hi,I just yeasterday started to play with htmlreportgenerator and html as format is new to me also.After playing one day with it, I managed to make with small effort make point in map and make some charts out. Now was thinking if there is some "easy" way to make those together?I have about 300 points in map what show their label when they are clicked. How much html_content I would need to modify to make charts pop out instead of label? All of these points have their own charts. To make it simple.. 300 points and 300 charts. How to make them together? :)Aki

Custom gsd file.

I have a custom gsd file provided by our client to go from NAD83(CSRS) UTM zone 18N (or EPGS 2959) to UTM83-18 (or EPSG 26918). Using the data read with these projections or datums, and trying to relate the two spatially within FME, produces no overlap between the features. Whereas, there is only suppose to be a 1 meter shift between them. When I try to edit the FME desktop options to point the transformation screen to this gsd file, it gives me an error "failed to override grid...contact SAFE."

snapping lines with different distances

Hello,i have a big network(_network_ID = 1) as displayed in the left section of the picture below. The right section shows some lines(_network_ID = 2,3,4,5,6,7) which are not included to the network yet, but are networks of their own. I would like to snap each neighboring line with each other and then snap it to the big network, which should be easy using a Snapper Transformer.Now to the problem. Some of the distances between those lines require a snapping tolerance bigger than the distance between their own end points. So some lines snap to their own end points. How can i avoid that?Many thanks in advance,Andreas

FME Server Shortest Direct URL

Is it possible with FME Server to create a shortest direct URL? (like in Google Maps, when we share a map, we have this option)I've pasted my URL in Notepad and it seems that I have 500 characters.This is not a beauty into an email and it is not so nice to copy paste for anyone.And for a newbie, all the information into the URL isn't very useful.Thanks.

The snapping type is set to 'End Point Snapping'.The problem is that some lines have both end points in the required snapping tolerance, so both end points get snapped.I cant reduce the snapping tolerance.

How to test if the sub-set value of an attribute is correct?

Hi, I have a dataset I want to check matches with another one. In particular I need to make sure that if the business area names match between the 2 datasets that the sub-business area listed is one named under that business area. For example if in the 1st spreadsheet;Business area = Environment, Sub-business area = River or Forest Business area = Air, Sub-business area = Quality or Pollution.Then in the 2nd spreadsheet, if the Business area is Environment then the sub-business area should only be River or Forest. If is it Quality then I need to know this is incorrect. Also is there are way of doing this without having to list out all the sub business areas (e.g. if you used a tester with environment = river, forest,etc).Thanks in advance and also happy to clarify if what im asking isn't clear.

Directory and File Pathnames - wrong timezone

We use a Directory and File Pathnames to extract filenames and path_created_date and store the value for all new files in a database.When we move to summer-time and winter time, it seems that FME gets 1 hour different and adds all files again. So I have checked the following, to see if the timezone settings were off:FME Server: own custom server - Western europe standard time - UTC+1 Database: MS SQL - Not sure File server: - Western europe standard time - UTC+1This is really annoying - and it would be great with a universal solution. Any tips or someone had a similar issue?
