Hi EdLoach
This is classic use of Terracer for myself, and which results in JOSM throwing an exception when ‘OK’ is clicked:—

1. Use Building_Tools (press ‘B’) and draw a block for a house
2. Select both the house & the street
3. Use Terracer (press ‘Shift+T’ to receive the Terracer dialog)
4. Enter Lowest Number / Highest Number / Interpolation as appropriate
   (I have used Terracer to produce both detached, semi-detached + actual terraces of houses successfully in the past; all of those produce software-exceptions now)
5. ‘Segments’ will auto-represent the calculated number according to the previous options chosen
6. ‘Street name’ is also auto-selected with this sequence
7. ‘add to existing associatedStreet relation’ IS selected
8. I always got a software-exception if ‘keep outline way’ was NOT selected. That behaviour continues with the most recent release.
9. I get a software-exception if ‘keep outline way’ IS selected. That is new behaviour, only occurring with the most recent release.

My setup is Linux Debian 8.5; Linux 3.16.0-4-amd64

(correction:— Debian updated 4 June, but I updated my system on 5 June)

@Hjart:
“Hammering”? Am I not allowed to mention the fact if JOSM throws an exception when I use it? What strange use of language.

Hi Jerry

Thanks for the Wikipedia Map; I’ve also read the nottstalgia.com forum that it originally came from. Unfortunately, whilst the map shows Carlton Road (the large road running towards top-right) & the (now discontinued) NSR railway-line (vertical line on right-hand-side) and therefore the bottom of Porchester Road (where the black-line crosses Carlton Road) + Burgass Road (coming off Porchester & running parallel to Carlton Road) the map stops well below my recent surveys. In fact, I cannot yet find any mention of bombing damage in the Morley Road area.

Hi Martyn

Thanks for the link; an interesting read. However, I have a correction for you:

That house at 745 Woodborough Road is actually 752 Woodborough Road. Odd numbers are on the other side of the road.

Hi Warin61

“When you have the funds/inclination it may be a good idea to get a second PC as backup?”

As soon as I send the Crucial memory off to be replaced I will have the old PC as a replacement. In fact, even better, I have an old 1TB USB disk that I use as backup, and then a 400GB RAID-10 CentOS-5 server known as Olivia for even more backup (unfortunately, appallingly noisy as it is intel ISA with a SCSI card + discs, and the temperature-reactive disk-fan is operative only with the intel-SCSI BIOS).

Many thanks for your comments CloCkWeRX & Richard. I’m now going back to mapping.

Hi jonwit

I found that link to the Census Bureau Safety Tips really useful - thanks!

Hi Glassman

I’ve moderated my comment about his height, slightly.

I was a very short child, and was badly bullied as a consequence (until I punched a tormentor in the throat, and it stopped; I was aiming for his nose but wasn’t tall enough to reach it). That experience caused me to become a bully. By the time I realised it, I was no longer short, and it was all a touch dangerous.

You may be disappointed, but life is what it is, whether you like it or not.

A little comment on the photos + bandwidth:-
In the text I pointed out that for some days – including the 1st 3 days of May – I was using my personal site to provide the 13 photos featured in the body of the Diary entry, whilst Mapillary was used only as a link to each of the GPS-registered photos on their site. After the Bank Holiday I got a reply from Mapillary to my request for assistance, in which they pointed out that the “Photo Description | Download” menu item would give a link to a JPEG url that could be used for that purpose (Diary display). Hooray!

This afternoon (UK time, GMT +0100) I changed all the photo URLs from my personal site (altervista.org) to Mapillary (cloudfront.net).

Just now I got an auto-email from my personal site host:

Subject: Bandwidth usage (monthly estimation account etmg)
From: “AlterVista” nobody@altervista.org

Dear Webmaster,

your site has generated thus far more than 13 GB of traffic. At this rate the traffic generated will be over 132 GB by the end of the month, while your limit is 30 GB, so it is possible that your site will become unavailable for some days before the end of the month.

(whoops)

Those 13 jpegs total up 11.3 MB. That suggests 1,150 unique page-views to cause 13 gig of bandwidth, which is actually not much (I ran the website modem-help from 2003 until last year, and that had daily visitors of 5,000 minimum) (15,000 shortly after inception).

@Warin61: I’ve no problem with neighbourly concern – it is just what you want to deter bad lads in your own area – but individuals can take it to extremes. I’ve already had one incident whilst I was tracking with a man pushing his face into mine. I calmly asked him if he realised that his behaviour was intimidating, and after a couple of moments consideration he began to calm down (it probably helps that I was bigger than him, but I also had nothing to hide and do not panic easily).

I’m simply trying to give intelligence distilled from my own experience, hopefully leavened with a little humour, and designed for others entering the same territory. As the sergeant in Hill Street Blues said every episode: “Hey! Let’s be careful out there”.
