PoI Musings

Before

This was originally posted by myself on 5 June 2019; it is another Diary as part of mapping Nottingham’s Creative Quarter, this time musing on Points of Interest (PoI) as part of mapping for OSM.

One of many reasons for entering PoIs in the map is that Nominatum (the search facility within OSM) uses PoI to find results including (amongst other items) postcodes. I discovered this when I could not find the Covid-19 Jabbing-centre in the OSM map, yet confirmed afterwards that I had entered the correct postcode.

A conversation with the lady at AST Auto Centre

I could not be certain either from my original visit nor from our Bing imagery whether some central buildings were occupied by the Ashley St. Auto Centre (below) or by a business on the opposite side of the block on Handel Street, so phoned the number on the business card that the lady at AST had given me on 17 May. This was 4 June so I did not expect her to remember me but she did, and mentioned the little leaflet that I had given her.

I quickly sorted the original reason for the call (AST occupies those buildings), but as soon as I mentioned OSM she immediately responded about the number of enquiries that the business gets via Google maps (I had never mentioned Google). I brightly informed her that the updated mapping should be available within the next hour.

SEO == “Search Engine Optimisation”

(this is almost always a euphemism for “SPAM”)

In a former life as a website owner & operator I spent my time fighting to keep spam out of my site forums + trying to keep the site firmly within Google’s gaze. Whilst many spammers are profoundly stupid, it was not lost on me that there is some fierce intelligence at play behind the entire spam business, else they would have long ago dissolved into the void. I was not too proud to learn from these experts where I could find it, at the same time as I did my best to kill them dead on my site. I attempt to put all the SEO intelligence that I have gathered into practical application with these diary posts, as one example, making them as attractive as possible firstly to the human readers but also to the bots operated by the Search-Engines. If both find them attractive then OSM wins again.

I was very interested in the response from the lady at AST. It was the first time that I had had such positive feedback on the idea of OSM, and it seemed a good endorsement of both the promotional leaflets (well done to Andy Allan) and also of OSM.

I’ve spent 30-odd years of my life as a professional salesman, and therefore it often colours my approach to things. With OSM it was immediately obvious that the map is a boon for every business — what a marketing opportunity! I therefore work tirelessly to promote every business that I meet during my surveys. (For newer mappers: in OSM-speak these businesses are called ‘PoI’, which is to say “Points of Interest”) I collect Business Cards/Compliment Slips/Brochures whilst mapping so that back at home all of the business’s most important contact information can be put up on the map. If the OSM map is an easily-referenced source of information for most businesses, then it will become very interesting for the common customer, which is good for customers, good for businesses, and good for OSM. The kind of virtuous circle that we need.

Public Service Information:– Business Cards, Compliment Slips, Brochures

For the benefit of younger mappers, since I’ve often had young folks telling me that they do not know what I’m talking about when I’ve asked for one of these items:–

Business Cards

These are dead trees processed into stiff paper (ask your teachers if you are unfamiliar with the idea of paper) and then printed with the business, personal name of the business owners + address & contact numbers. They are intended to be given to other people during personal meetings to facilitate marketing promotion of the business. Please approach your health professional if you have been triggered by the idea of a one-on-one personal meeting, but this is actually quite normal during business life.

Compliment Slips

These are dead trees processed into (typically) a ⅓ of an A4 sheet of paper (ask your teachers if you are unfamiliar with the idea of paper) and then pre-printed — normally on just one side — with the name, address & other contact details of the business. They are intended to be placed into the same envelope as a letter. Ask your teachers if you are unfamiliar with the idea of an envelope or a postal-letter.

Brochures/Booklets

These are dead trees processed into (typically) a series of A5 sheets of paper (ask your teachers if you are unfamiliar with the idea of paper) and folded (brochures) or bound (booklets) after pre-printing with information about the business & it’s activities.

A final item, often overlooked it seems to me by others, is that these Diaries are a very good method to put up URLs in the map that can be indexed by the SEs.

Update 21 June 2022

Mapillary has changed it’s download URLs & therefore all links within my diaries that used a Mapillary download URL in the old format are broken (the Mapilliary map URLs, which show a photo within the context of an OSM map, have also changed and are redirected via a HTTP/1.1 302 Found, but the download URL hostname no longer exists and gives a “No address associated with hostname” DNS error). I’m slowly going through to update them. The new URLs are terrifyingly long, but show OK on my screen (and I hope also on yours).

Update 7 July 2022

I discovered just now that the Mapillary photo on this page was broken yet again, as are others that I updated on other diary pages. Loaded into a web-page by itself the download-URL gave the error: url is timed out. It seems that Mapillary has decided that these freely-donated photographs can only be used for it’s benefit.

As a heads up, the Mapillary images now have a rotating URL. You should not depend upon that URL for embedding images. If you do want to embed an image, you have to use an iframe. With that said, I don’t know if diaries allow iframes. They probably shouldn’t.

I.e.

<iframe 
  src="https://www.mapillary.com/embed?image_key=550092599700936&style=photo" 
  height="480" 
  width="640"  
  frameborder="0">
</iframe>

See https://www.mapillary.com/developer/api-documentation/ for more api documentation.

Thanks for the link to the API v4 documentation.

I’ve recently made another diary explicitly about these Mapillary changes see diary/399529. The photos in my diaries are all Download photos, which do NOT feature in the API help page. Those IDs are way more extreme than the example above, and there is no evidence so far that the URLs have rotated (the photo in this diary post has an identical URL to the original, I have simply refreshed it on the Mapillary page, when it began to show again. The API talks of Refresh Flow & access tokens expiring. I suspect that something similar is being utilised). I mentioned an older page in my diary whilst within the Nottinghamshire Archive building & the gentleman there was able to bring up a page & see the photos (which had been refreshed recently).

I’ll try the method suggested tomorrow (I need to get to bed!) & report back (in fact I just tried it in this comment & no deal; here is the url as a link to a new page.

Tried it within the diary exactly as you & the v4 API suggested using this src, but it just will not work within an <iframe> (nothing whatsoever shows in the screen, and ditto within these Comments). I also tried it within a <div> & within a <span> (with an <img> internal to them) & also with a bare <img>. With those it shows a broken image icon + the border when applicable.

The entire point of an <iframe> is to provide foreign soil within the webpage (I think of them as a similar notion to that of a foreign consulate within a country), and clearly OSM will not allow foreigners upon their soil, and Mapillary will not allow the photos that they host to display otherwise, so we are at a standoff.
