I'm trying to follow the video, FTTx / FTTH network planning in QGIS free software with the provided GNI_FREE_(EN)_1_1_2 plannerFTTx sample.

I get an error message at Step 1 (2mins 35 secs into video) which states:

Algorithm (step 1) create GPON demand and route line from OSM starting...
Prepare algorithm: GNIPLANNERFTTHCHECKWORKCONTEXT_1
Running Check work context (1/16)
Parameters:
Failed

Error executing algorithm Check work context No work context available.

Any idea what the problem might be?

My system details are:
windows 10 64 bit
QuickOSM 1.4.6
Grass 7.2.2
QGIS 2.18.15

Thanks

Hello,

You have to create and open a work context in ‘WorkContextTracer’ plugin.

Please, follow the instructions described in "GNI_Short User Guide for FTTx Planner.pdf" chapter 5.

thanks. Can you provide a link to the document? Google can't find it and it's not in the Documents section of the GNI website.

Ian

The "GNI_Short User Guide for FTTx Planner.pdf" is distributed with GNI Free package (the zip archive you have downloaded).

thanks. Yes, I do have that. I thought you meant another document.

Many thanks

Ian

I now have a work context but still get an error with Step 1. This time it's:

Algorithm [step 1] create GPON demand and route line from OSM starting...
Prepare algorithm: GNIPLANNERFTTHCHECKWORKCONTEXT_1
Running Check work context [1/16]
Parameters:
Converting outputs
OK. Execution took 0.003 ms (0 outputs).
Prepare algorithm: GNIPLANNERFTTHGETLAYEREXTENT_1
Running Get work area extent [2/16]
Parameters: INPUT_LAYER =memory?geometry=Polygon&crs=EPSG:4326, CRS =, PROJECT_CRS =True
Failed

Error executing algorithm Get work area extent 'NoneType' object has no attribute 'xMinimum' See log for more details

Can you help with this one too please?

Thanks

Ian

This error can occur when an input layer is empty (has no polygons in it).

Please, make sure your input layer for step 1 algorithm is not empty and select polygons which represents your working zone.

I beleive I have a non-empty layer. See screenshot at:

Please, attach the screenshot to a post.

the editor says the file is too big (695Kbytes) to attach.

Are you unable to access the url I sent?

Thanks
