RasterCellCoercer and PointCloudCoercer return different results

Hi,I tried to optimize an existing workflow by replacing all RasterCellCoercers by their PointCloud equivalent as described in:https://knowledge.safe.com/content/idea/22245/spatial-statistics-on-raster-data.htmlI however noticed that there is a small difference in the way the raster values are returnedExample: My original raster value is equal to 23.835The RasterCellCoercer returns 23.835.The PointCloedCoercer however returns a value of 23.834975...When I round these values to 2 digits I get 23.84 and 23.83, depending on the method that was used to extract the raster values.I think this has something to do with the fact that the data type of the components is changed to 'Real64', as described in the logfile:'PointCloudCoercerFactory: Converting component 'z' from type 'Real32' to 'Real64'. If this conversion is undesired, consider changing the type explicitly'Has anyone experienced a similar issue? Any suggestions on how to tackle this problem?

I am trying to test an entire field to see if there are any populated values.

It is a large data set. If there are no values, I want to send the data to a writer, if there are any values, I want to go to the terminator. My issue is that the data set is large and using a tester or attributeValidator isn't work because values are getting to my writer before validation is complete.

When translating to SDE using SCHEMA_FROM_TABLE, is there no way to assign attribute Name aliases?

I have my SDE destination schema in a file. But I don't see any parameter for Attribute Name Column Alias. So I'm guessing there's no easy way to assign Attribute name aliases. If I'm wrong, would love to learn how to do this.

InLineQuerier: Is it possible to Use an inbound Field as the WHERE Clause? Possible syntax error.

Hi Folks, I have successfully done a Cross Join In one InlineQuerier where the contents of a field called Query_Filter - is the WHERE Statement I want to apply in another InlineQuerier. I can get the statement to work fine when I paste it in to the second querier - EG Select * FROM "Detected" WHERE (ChemCode ='7440-38-2' AND Concentration > 160 )However when I Write SELECT * FROM "Detected" WHERE Query_Filter It doesnt work. (Query_Filter just containing the text string above.)Im missing something. Any thoughts ?

FeatureReader HTML Table with authentification

Hi folks !I want to read HTTP tables for a bunch of url stored on an attribute of my features. However, a basic authentification is needed to access the page.If I set the attribute containing the URL in the source dataset of the feature reader, I cant set any authentification parameters.Everything is working fine if I manually enter one url, then go to the parameters. (as if I use a Reader)Any clue on how to use this authentification in the FeatureReader ?

topology builder create nodes/lines on intersections even data is clear !!

Hello,I'm using TopologyBuilder to topology of my network.My data is clear and I want to build topology using start/end points (Nodes). It's working fine for me, but I have a problem with 2 cases (similar case) (from 3000 lines).the tool is creating complexe intersections. So, splitting lines, creating additional lines and additional nodes !!the problem is when two line are almost parallel for a while, please see below an examplebut I don't want that, I want to keep the original lines and create just two nodes for each. this result distorts my network.do you have any idea about this strange behavior ? do you have any solution ?Thank you :)Youssef

Publish to FME Server

Hello, I have one main workbench which in turn executes other three workbenches. I used shutdown Pythin script to execute the other workbenches from main workbench. I am new to FME server and I need to publish this to FME server so that it can accessed in Java Application. I have few questions on this 1. As which type of service I would be able to publish e.g. Data Download Service, Job Submitter etc. 2. Do I need to publish all four workbenches (main plus three workbenches) to FME server? 3. What is the best way to publish this as a service. 4. Are there anything I have missed and should consider before publishing as a service. Thanks.

How do you use the RCaller and FME?

Here at Safe, we are always trying to improve FME as well as our Knowledge Center articles. It recently came to our attention that we don’t know much about how our users integrate R and FME using the RCaller transformer and the great things they are accomplishing with it!Our questions to you: How do you use the RCaller transformer?Are there any RCaller related articles you would like to see?

2017 performance issues with Point On Line Overlayer

Has anyone else experienced performance issues with the Point On Line or Point On Area Overlayer? In 2016 I have a workbench that does some overlays of about 700,000 lines with 2500 points and it runs within about 30 min (most is reading in features for other parts of the process). But when I try to run it in either 2017.0 or 2017.1 I get to a point where it says, "Creating spatial index" and it's been at it for hours. I tried upgrading the transformers to the latest version, with no change.Just wondering if anyone has any ideas or has had a similar experience.

Access SQL Creator Info in FME Server PostgreSQL Repository?

I wasn't able to find any schema documentation for the FME Server repository, is there any public details I might have missed? Essentially just trying to query source and targets for each workspace. Was able to query this information for readers and writers but we often use "SQL Creators" and/or "Joiners" to pull in tabular information. Is there a way to access those from the repository database? To list out the connection name would be great or even grab the SQL?Here is what we have so far:SELECT fme_item.name AS "Workspace", fme_item.title AS "Workspace Title", fme_item.username AS "Username", fme_item.lastpublishdate AS "Publish Date", fme_dataset.location AS "Data Location", fme_dataset.format AS "Data Format", fme_feature_type.name AS "Table/Feature Name", fme_repositoryinfo.name AS "Repository", fme_dataset.is_source AS "Is Source"FROM public.fme_item, public.fme_dataset, public.fme_feature_type, public.fme_repositoryinfoWHERE fme_item.item_id = fme_da

How to derive width (polygon) at point feature locations.

Hi,I am trying to calculate the width from a polygon at point feature locations (see figure). I was thinking about creating perperdicular linen at the point feature locations (perpendicular to polygon). Clipping the perpendicular lines (using the polygon as clipper) and calculating the length of the perpendicular lines. Is there an easier way to do this?Kind regardsMichael

LineOnAreaOverlayer - Road polygon attributes to centrelines

Hi all,I have a polygon layer representing the sealed area of our road network with numerous attributes about the road. I also have a road centreline layer which has no attribute information. I want to get the road polygon attributes applied the appropriate centreline. The obvious transformer is the LineOnAreaOverlayer, however, this creates a lot of 'stub' centrelines that get associated with an intersecting road (please see image for an example). In the example, a small section of Road 2 is given the attributes of Road 1.So far the methodology that I have come up with is to:1. assign a unique identifier to each centreline2. process through the LineOnAreaOverlayer3. determine the lengths of each segment 4. combine segments based on unique identifier 5. use the attributes of segment with the greatest length for the attributes of the centrelineIts not ideal as there is potential for error, so I would be keen to see if anyone else could come up with a better methodology.Thanks as
