Penang Island Tracks Pt 2

[tympg]

Evergreen-Halia Area off Mt Erskine:

Retracked some roads which are offset by a fair bit in the existing map. Also found the name of a previously anonymous village area, Elsiedale Estate.

The GE offset in this area varies a lot so I have put down some markers to indicate the offset of certain points in the area. These markers should be discarded for the actual map.

Just north of the previous post, some more roads realigned or added:

I found some road alignment is a bit off. How far off then I should submit a new track, is >5 meters enough for re-alignment? Thanks.

Have a look at your tracks?

Have a look at your tracks?

Here are 2 examples

1) Track 36 & 37 - along Pengkalan Weld - Jelutong Expressway - certain section out by as much as 13m. giving that each lane is about 4m, that is more than 3 lanes off. IMHO track should not off more than 2 lanes for a 3 lane expressway.
2) Track 40 - road bend along Lebuh Bakau - not the right shape and out by about 11m.

Pls let me know if these are something that I should submit for realignment as I have many more examples in my collection of tracklogs. Thanks.

kaybee,

Checking with Google Maps, your Lbh Bakau track looks good versus the current road on the map.

For the Weld-Jelutong Expy tracks, bear in mind the road (south-bound carriageway) is at times 4 lanes wide.

Compare with my tracks from last year:

I would say that in general, just submit your tracks if you feel the alignments warrant a review, and let bro OngCC judge each case on merit.

Cheers.

tympg,
When doing tracking, do you track the left, middle or right side of the road before the road divider?
Rgds.

Preferably the middle lane of the carriageway. But of course, the situation may not always allow for that.

Ya, maybe running multiple tracklog on inner and outer lanes would give a better picture of the road accuracy. Thanks.

Retrack Lebuh Bakau due to road bend on the southern part is not quite right in MFM 1.45.
