[mkgmap-dev] Commit r4292: Fix problem with long roads producing the error message "internal error? The nodeCount doesn't match value calculated by RoadNetWork"

Wed Oct 2 10:18:59 BST 2019

Hi IMG experts,

the message is produced because we have to different ways to calculate a counter which is written to NET. It is not obvious which one is correct and therefore we
have a check that compares the counters. Some special cases only occur with polish (*.mp) input, others only with osm data.

I've now started a new branch called "NET-no-NOD" to improve the code so that it 
- supports writing NET without NOD data from polish input
- doesn't write redundant data into RGN when neither housenumbers nor NOD data is present for a road
- ignores empty POI instead of crashing (special case for John Thorne)

This is complex because in OSM data each point (Node) has a unique ID while in *.mp this is not the case.
On the other hand with *.mp input the user can produce roads which have only one routable node in the middle (+-shaped crossing).

I  think the branch already works better than trunk but testing is complicated. I test these fixed options --index --preserve-element-order  --bounds=f:\osm\bounds.zip 
in combination with
1) --net
2) --route
3) --net --housenumbers
4) --route --housenumbers
both with various *.osm and *.mp data. 
Whereever I  find differences in the IMG output I try to find out if the new result is an improvement or not. I use Mapsource to test effects on routing and the display tool to analyse the differences in the RGN, NET and NOD files...

Hi Ticker,

thanks for the details, I've reverted the problemtatic patch for now, so r4294 should work fine for most users (except John Thorne)

Hi

I've minimised the options and still get the problem.

Downloading this morning from:
http://download.geofabrik.de/europe/great-britain/wales.html

java -Xmx1540M -ea -jar splitter-r592/splitter.jar --mapid=74320089 -
-split-file=tstSep19.list wales-latest.osm.pbf >splitter.log 2>&1

where tstSep19.list contains:

4320089: 2398208,-194560 to 2437120,-155648
#       : 51.459961,-4.174805 to 52.294922,-3.339844

Then, with latest bounds downloaded from the link on mkgmap.org.uk

java -jar mkgmap-r4293/mkgmap.jar --route --bounds=bounds.zip --input
-file=74320089.osm.pbf

I get:
