[mkgmap-dev] Example of logging Echotags to file

From Joris Bo jorisbo at hotmail.com on Sat Mar 24 18:49:10 GMT 2018


Thank you, that was the trick !
I'm trying to show a thin border (line) around Boundary = nature_reserve on lower zoomlevels based on the size of it and another thicker linetype at higher zoomlevels.

Question 1
>From within the Lines-file I would like to have the result of the length() and area_size () function in an echotag result variable
I only get errors when trying to add tags or set existing tags to these function values
Does somebody has an example?

Question 2
Is it possible to retrieve the area_size() of an mkgmap:mp_created multipolygon from within the lines file? For me it looks like it always returns 0

Hi Joris,
I'm using java .... 1> mkgmap.log 2> mkgmap_error.log
In that case you will find the echo-tags in mkgmap-error.log together with all other error-messages send to stdout.

I tried a lot already  like:   java > c:\temp\log.txt
The logfile is created but the log only shows basic info and not the Echotags info

Thx in advance
