"Area on area overlap" sum Calculations in overlaping areas

I have got an amount of points which are the locations of fire hydrants. Each of it can deliver a certain amount of water (Liters / Minute) in a radius of 300m for firefighting purposes.I have created a buffer around each point and now I want to calculate the amount of water for firefighting purposes in the buffers an in the overlap areas and in the non-overlap-areas. Example: I have Hydrant #1, which can deliver 2000 l / Min, and I have Hydrant #2, which can deliver 3000 l / Min. In the overlapping area, I have 5000 l/min of water supply, in the non-overlapping-area I have a water supply of 2000 l/Min (Hydrant #1) or 3000 l/min (Hydrant#2) respectively. Of course, there are many more hydrants to look at, and in some cases we have a dozen or more hydrant areas which are overlapping. I have used the "area-on-area-overlayer", which seems to work properly, but I don't know how to calculate the sum of water supply in the overlapping area. Is there anyone who can help?

Ability to leverage In-memory SQLite/SpatiaLite DBs

Fun fact, is that FeatureWriter writes to a database path of ":memory:" for SQLite and SpatiaLite formats (or seems to at least). For SQLite buffs, this is a virtual database instance written entirely in RAM so cuts down on disk/temporary file overheads and is highly performant. It is a feasible way of combining in an FME workspace non-SQL, procedural type transformers together with the power and lower overheads of the SQL engine contained in SQLite when your features also happen to be highly data relational and can be indexed (plus take advantage of the extensive spatial library functions that come with SpatiaLite as well)However, for the life of me I can't figure out any way to use an in-memory SQLite DB from there in a workspace, say with an SQLExecutor. It seems as soon as FeatureWriter finishes it closes the connection to a database written to ":memory:" and no further reference is held to it (and because the DB is volatile then the Transformer essentially

InLineQuerier Data Types, Numeric, Real or Float?

Per SQLite documentation, Real and Numeric are supported and Real is of a Float type. However in InLineQuerier Numeric is not an option, only Real and Float to pick. Due to precision issues of floating point, we would prefer to use Numeric in several cases. Please advise.

Using attribute from a different element

Hi all, I have two source of data, one is introducing an ID code, the second one is a point cloud. After some processing on the point cloud data, I want to use the ID code (coded as a number) as an attribute to offset the point cloud in z. (I actually want to offset z using both the ID code and the Min value of the point cloud). The 'Aggregator ' is messing the point cloud. I also tried featutre merger with zero success. Digging into this issue, i found myself unable to do any attribute I don't find the way to add, merge or replace attributes of the point cloud (or a TIN based on a point cloud) with attributes imported from another data source. Thank you for your help! Jorge

Gzipped text file problem when overwrite existing file is "No"

When "Overwrite existing file=No" in a text file writer, new data is appended to the end of the file. But if the file output is gzipped then existing file is overwritten. I am testing:The first output is gzipped and the second one not.If I execute the workspace () several times, the .txt file grows but the .txt.gz not. Any suggestions?

SchemaMapper Filter

What does the "Blank Attribute Value" do? I am having a hard time finding it in the docs...

I need to use the FTPCaller in FME Desktop but I can only connect to the SFTP Server via a .pem key. However, as it is not an area I've really used before, I'm struggling to understand the authentication method. I'm fine connecting when authentication not required, it is just that I need to use a .pem key and I'm not sure how to reference this in the transformer. Any help would be grateful.

Transform from NAD83-Original (1994) to NAD83-CSRS for areas which don’t have a provincial grid shift file?

How do I transform from NAD83-Original (1994) to NAD83-CSRS for areas which don’t have a provincial grid shift file? (e.g. Yukon, NWT).All new incoming data are NAD83-CSRS and I want to bring our older holdings up to match. I don’t have confidence in the automatic methods chosen by ArcMap/Pro/others in project-on-the-fly situations. I’ve seen too many instances where different coordinates are reported for same points from different methods.With csmapReprojector the process fails with:CS-MAP Reprojector: Transformation will be automatically selected for 'UTM83-8' -> 'CSRS.UTM-8N', and is not guaranteed to remain the same in future releases of FMECSRS :: Referenced grid file does not exist or cannot be opened for reading.A fatal error has occurred. Check the logfile above for details...CsmapReprojector (TeeFactory): CsmapReprojector: Reproject: Could not reproject the geometry of the preceding feature: CS-Map Reprojector: Unable to load grid file for 'NAD83_to_CSRS' | CS-Map Reproject

Question of the Week: Memory Management and FME

Hi FME'ers,Today's Question-of-the-Week queries a log message about memory usage. The concern is what the message means and what can be done about it. Question of the WeekQ) This warning is appearing my log files:Failed to free sufficient memory to reach the process usage limitWhat do I need to do about it? What is the potential impact if nothing is done? As far as I can tell there is nothing wrong with the output files the script is creating.Asked here by @maphewA) In short, this message tells you that FME is becoming short of memory. If you don't do anything about it then - as long as the process finishes - you are correct that the output will be fine. But let's dive a bit deeper into why this message occurs...Memory ManagementSo, FME has built into it, tools for what is called Memory Management.

Denormalise Spreadsheet

Hi, Having trouble describing my problem to Google it, so apologies if I've used the wrong term or missed something obvious here. I'm just starting to use FME so please be nice! :D I have a spreadsheet which contains owners of properties in this format:PropertyOwner 1 NameOwner 1 Addr1Owner 1 Addr2Owner 2 NameOwner 2 Addr 1Owner 2 Addr 2 And so on for up to 4 owners per property. Properties with one owner have blanks in the Owner 2/3/4 columns. I'd like to reformat this to individual records for each owner, like this: PropertyOwner 1 NameOwner 1 Addr 1Owner 1 Addr 2PropertyOwner 2 NameOwner 2 Addr 1 Owner 2 Addr 2 PropertyOwner 3 NameOwner 3 Addr 1 Owner 3 Addr 2 PropertyOwner 4 NameOwner 4 Addr 1 Owner 4 Addr 2 In the real file there are several property columns that I'd like to copy down to all other rows for that property, and obviously if there is blanks I don't want to create new rows.Is this possible in FME? Can anyone point me in the right direction? Thanks,

WCS bounding box within Feature Reader

Hi,I would like to read data from a WCS service in a way that it reads only the part of my projectarea. It seems that the way to do this is using a Feature Reader and use an spatial filter in the Feature Reader. Unfortunatly this is not working. The URL created has the wrong bounding box value. The error I get is: "returned Content-Type 'application/vnd.ogc.se_xml; charset=UTF-8' is not supported". I can read the exact data using the WCS reader by using the search envelope, but this is not what I'd like.Another way is to compute the extents in one workspace and call another workspace with the workspace runner with the extents as parameters. But it should also be possible withe the Feature Reader.Anyone any idea how to fill the bouding box within the Feature Reader for a WCS service? Greetz,Arno

DWG Paper Space and Model Space Standards

Hello All,I am seeking some advice on how other organisations have tackled Paper Space and Model Space validation from an incoming DWG.We are trying to come up with some drawing standards that will facilitate a cleaner / easier validation of the data and presentation of the drawing.We are suggesting that all elements be drawn in model space so that we can validate text labels against the actual line angles and distances. But the drafters need to use viewports in paperspace to generate enlargements of certain parts of the data and we need to validate that the data in the viewports is correct.Do any other organisations have standards on how drawings should be put together in both model and paper space so that data and presentation elements can be validated simply?

how to update metadata in file geodatabase with multiple feature classes with feature writer

Hello,I have a workbench that updates metadata by reading a file geodatabase with multiple feature classes. The multiple feature classes will change every time, i.e. in effect I want to update metadata for all feature classes in a file geodatabase based on excel provided for every feature class.I am reading the file geodatabase with directory and file path reader and then using feature readers for file geodabase and raster dataset. They need to be split as raster dataset has a separate reader.Then I am updating the metadata for each feature class based on input excel, which works fine.However, I cannot write the metadata back to the original file geodatabase feature classes using either feature writer in a dynamic way, i.e. write to all feature classes in the file geodatabase or with a dynamic file geodatabase writer.I am getting errors and I run out of options on how to do it.This is how I am reading:And this is how I am trying to write the updated metadata back to file geodatabase on

Merge two features on epochtime with in-range time comparison in milliseconds

Hello, I have one dataset, the epoch time on that is approx. 5HzI have another dataset with epoch time and that is in 20Hz, it covers several different 5Hz datasetsThese two features do not share a perfect match in milliseconds.I want to merge the 5Hz attributes to the geometry of the 20Hz. NeighborFinder does not work since the 20Hz has geometry from several different datasets in close proximity.Both datasets contain timestamps which merges succesfully in FeatureMerger, however these matches are sporadic.I cannot round the milliseconds to more than 3 decimals, since that will degrade the solution of the 20Hz.I was thinking of an inlinequery with an SQL query that performs an epoch timematch based on a 0.005 second in range since that would be the unique identifier. However I do not know how to fully structure such a query. Regards,Robin
