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

Salesforce reader error

I am using Salesforce reader to read files from data loader - is this the correct approach?I am getting the following error when I use the custom domain (https) with username and password (with or without security token): "Failed to obtain any schemas from reader 'SALESFORCE' from 1 datasets. This may be due to invalid datasets or format accessibility issues due to licensing, dependencies, or module loading.

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.

anchored snapper snaps both endpoints of one feature

Hello,i use an AnchoredSnapper to snap lines(candidates) to points(anchors). 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. So is there a way to avoid this?Many thanks in advance,Andreas

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?

Exposing a raster band value and creating an attribute from it

@takashi As you have probably worked out I'm fairly new to more than push button FME. This should be really simple and probably is but I want to expose a numeric raster band value and create an attribute from it so that when I covert the raster to polygons I have the value as an attribute of the polygons. I have tried using attribute creator but can't work out the syntax. This leads on to another probably basic and related question: I want to replace values in a raster based on ranges of numbers - eg 0-12 becomes 12 and more than 12 but less than 20 becomes 20, etc. I can string together multiple instances of RasterCellReplacer to approximate this but there must be a more efficient way using RasterExpressionEvaluator for example. Again my syntax to do this is lacking. Any resources for a self-taught FME'r on that front that start at the basics?

FME 2017.1 Miscellaneous

I'm now working with localization of FME Descktop 2017.1. It's also a good opportunity to take a closer look at what's new. I would post something I noticed through the job.FME 2017.1 build 175391. ListBuilder The "Input Ordered" parameter seems to be shown at a wrong location.   2. NeighborFinder It's great that the new parameter "Take Measure/Z From Candidate" has been added. However, I'm not sure if it's reasonable that "Yes" is set to the parameter by default. How do you think about this? possibly to be continued...

How to create a PRJ file that is the same as the PRJ produced by ESRI?

Hello. I am using FME 2017.1The issue I am trying to resolve is stopping the ArcGIS Transformations window from popping up when I add a shapefile that was created by FME. The FME shapefile is in the correct projection (same as the dataframe) but the FME PRJ file is slightly different than the ArcGIS PRJ file. I am assuming that this is what is causing the Transformations window to pop up. So, my question is: how do I create a PRJ file from FME that is the same as what ESRI expects so that the Transformation window doesn't pop up in ArcGIS?Here are the details of what I have done:Right now, the projection I am using from ESRI's ArcGIS is not in FME. The FME projection that is the same as what I am using is 10TM115-83.I created a Custom Projection by created a .fme file and putting it into the following directory (C:\\Users\\<<USERNAME>>\\Documents\\FME\\CoordinateSystems) as suggested on this form:http://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Workb

Vector to Raster conversion

Hi,I have a point Shapefile that I would like to recreate in raster, specifically, ESRI Ascii Grid format.However I am having issues in that when I use the 'NumericRasterizer', some of the resultant cells in the raster are up to 0.25m away from the original location of the points. Is there any way that I can set the rasterizer (or use a different transformer) to force the resultant cells to be overlaid exactly on the original points (ie: points will lay in the centre of the cell)?Thanks

FME as a visualization tool

Hello,this time I do not come up with a problem but with a request for ideas/opinions etc.The scenario:static geographic locations, where samples are taken on a regular and irregular basis are hold in different database environments such as Oracle Spatial and Smallworld Data Stores. The measuring values are hold in an Oracle non-geographic environment. There is an ID that connects both "worlds" (yeeepie!). Probably there will also be non-static sample places (ad hoc samples) in the future whose positions are not yet stored anywhere. Here, the question how the data will be georeferenced, has to be answered first. For this scenario I exclude these sample positions.The idea now is to join both worlds (geographic and non-geographic data) and visualize it in a map environment. Visualize in this context means:- overlay the sample positions with any WMS (own and third party) - delimit the sample positions by location and / or attribute(s) - select which type of, e.g. biological para

rgb channel order

Hi all,Upon creating rgb values it appears that the lueb and green channel are reversed.When I create the values with an expression evaluator and set them on objects (linear), the gradient is correct.In the raster however the blue and green are reversed. (swapping green and blue channel values corrects this)Is my observation correct? Is this intended?
