Tips to speed up process when clipping very large feature

Hi,  I am using the clipper on a dataset that contains many simple polygon features and few very large and complex features. I run the clipper in parallel processing and it seems to work correctly. However, the groups that contains the complex features take hours to complete while other groups with simple feature take few minutes. In this case there is no real performance gain with the parallel processing.  Do you have tips to speed up the whole process? Is it possible to divide the complex features in smaller part ?

Where are the Canadian geoids/vertical datums?

 Hello, I just sucessfully updated to FME 2013 SP2. The "What's new in FME 2013 SP2?" document states:  "Coordinate Systems: Added Canadian geoids/vertical datums, including CGVD2000/05/10 and CGVD28 (PR#44361)" However, looking under any "Coordinate Systems" transformers such as Repojector or CoordinateSystemSetter, I don't see any support for these datums.  Do I need to do extra steps before I can use these datumes? I suspect I may need to download a grid shift file?

Setting value to 'Feature Types to Read' from Publish parameter

I have two workbenches. First one will gather some feature type names and use workspace runner to call second workbench which should read only selected feature types. I found i can send these values via published parameter.  But i do not know proper format of listing these names in publish parameter for 'Feature Types to Read' that can be understood by oracle spatial reader.  Please let me know how to handle this problem?  Thanks, Subrat

How to create lines from polygons?

I'm doing a dgn to ArcSDE ETL of floor plan lines (fpl) using FME Desktop.  Some of the fpl are "shapes" in the dgn.  I don't know much about cad or dgn but I believe shapes are polygons.  Is there any way to convert these "shapes" to lines?  For example, there are some rectangular shapes.  Can one of these shapes somehow be exploded and converted into four lines?  Thank you

[FME 2011] String padder doesn't work

Hi folks,  I have a simple workbench taking an ArcSDE spatial table as input. In this table, I have a string field I want to fill with 2 digits. This field already has values, but a lot of them are only coded on 1 digits (1,Z,a...). I thought of insert a left pad and replace this pad with a digit of my choice (0 or Z) to make my field homogeneous.  But the StringPadder doesn't work... :-( At now, I don't have a writer, I'm only working with visualizer to see the potential result, and it's always wrong, I mean values still have the same length.  Does it make sense ? Any idea ? Thanks a lot, François

How to find lines that have the same start and end point

I have a dataset of lines, what i want to find and spit out into a csv file are the line records which run on top of each other and have the same start and end point. I initially started using the lineonlineoverlayer but it pulls every line that runs on top of each other regardless of the start and end points being the same.  Is there and easy way for me to find  just the lines i want? and which transformers should i use?

File Geodatabase Reader, single merged feature types-option ignored?!

Is there any way to make the File Geodatabase reader generic? It seems to be limited to the first feature type while using "single merged feature type" mode. Individual feature types is not an appeeling option...

Dynamically matching two unknown attributes

Hi there,   I’d like to know if there is a method to match attributes with similar names. To explain, here’s what the data will look like.   I have a Dynamic workspace that checks all files within two separate folder. So, the intent is to run this workspace on any features contained within, and the names of the shape files contained in those folders can be literally anything.   Let’s say Folder A contains the following files:   10001_AFR_ROADS_V1 10001_AFR_WATER_V1 10001_AFR_RAILWAYS_V1   And Folder B contains:   10XYZ_afr_Roads_v1 10X01_Afr_Water_v1 10001_AFR_Railways_v1_0   As you can see, there are similarities, but they are not identical. I want to know if there’s a way to compare the two sources and match any of those files that are “somewhat” similar. Ideally, a percentage. So for example, of it compare two of those files, and it detected that there was an 80% or higher similarity. I don’t need to see the percentage, I just need some leniency on matching the two sources up.   The

WGS84 format for float from a string.

I have some exif GPS data that I want to plot points for. These are strings:      jpeg_exif_gpslatitude    (54) (59.0226) (0)  jpeg_exif_gpslongitude    (1) (44.0662) (0)    My problem is - how do I get these into a format 2d point adder will use? I can easily strip the brackets, but then its still a string and I get this:    2013-02-18 17:01:35| 0.6| 0.0|ERROR |2DPointAdder: @Tcl2 -- failed to evaluate expression `FME_Coordinates addCoord {1 44.0662 0} {54 59.0226 0}' -- String value `1 44.0662 0' contains invalid characters and could not be converted into a float    Thanks.    Note: Sorry about the colour etc. That's what happens when you copy/past it seems and there's no "reset" button.

create readers?

In my oracle db I have 30 users, all of which have the same tables (about 40). Now I want to merge the data from the different users, i.e. create a new user with those 40 tables and combine the data from all 30 users.  I started by trying it for just one table and three users: I created a workbench with a reader for each of the different users and a writer to the new user, and everything worked well. As I want to automatize as much as possible, I used parameters for the user names and passwords, wrote them in a command file and started it as a batch.  But like that I still have to have a reader defined for each user in the FME Workbench. Is it possible to create the readers "on the fly" in the batch file? Or could I loop with the same reader through a list of my users / passwords?  Thanks in advance Vera

PostGIS: Non geometry tables not importable to PostGIS reader / writer any more

Untill FME 2012 I was able to import feature types of PostGIS tables to a PostGIS reader / writer no matter if they had a geometry column or not.  Since FME 2013 this is no longer implemented, the feature types import would only indicate tables with geometry columns to be selected.  In order to add non geometry tables to a workbench, one has to add an additional PostgreSQL reader / writer. This is not very agreeable. I wish the prior functionality back!
