What and where is the Ahaggar?

Posted by Linus Wolf on 1 June 2020 in English (English)

Charles de Foucauld’s Dictionnaire abrégé touareg-français de noms propres “Abridged Tuareg–French dictionary of proper names” is not only a valuable gazetteer of the Tuareg-inhabited central Sahara, but also a historical source capturing a time when European understanding of Tuareg toponymy had not yet taken on a life of its own.

One example of this divergence between traditional usage of local native speakers, and European reception, is the name and possibly the extent and nature of the Ăhaggar.

The Ăhaggar, clearly and unanimously, is a mountain range or mountain massif. In the early 1900s, Ăhaggar is also attested as the name of a country containing the Ăhaggar mountains. To my knowledge, the usage continues today (in the sense of a land, perceived as culturally or socially distinct, though not politically independent).

In Europe, it’s also known by the name Hoggar, a form which came about through contact with Arabic. Besides, the central part of the mountain massif is often introduced to tourists as the Atakor, apparently also giving rise to the geologically defined area of the Atakor volcanic field. Some overlapping area is now also protected as the Ahaggar Cultural Park.

I’d like to first and mainly look at the historical explanations given in Foucauld’s Dictionnaire, which are interesting as approximations to the local usage prior to major European (or other foreign) influence. After that, I’ll also go over some representations of the Ăhaggar in online databases.

The historical usages

The mountains

According to a first entry in Foucauld’s gazetteer, the Ăhaggar is …

la région appelée proprement Ăhaggar est le massif montagneux central du pays des Kel-Ăhaggar, massif de forme ovale, […] qui est compris entre 23° et 23° 30′ lat. N. et 2° 50′ et 3° 40′ long. E.

“The region properly called Ăhaggar is the massif of mountains central to the land of the Kel-Ăhaggar, a massif of oval shape, located between 23° and 23° 30′ lat. N. and 2° 50′ and 3° 40′ long. E.”

Let’s draw an ellipsis from the given coordinates:

Approximative border of the Ăhaggar when reading the coordinates as WGS-84

That doesn’st look like a mountain range. Turns out, as a French aristocrat Foucauld still used the Paris meridian in about 1910. Hence, shifting the location by about 2.33° results in a much more sensible perimeter:

Approximative border of the Ăhaggar when shifting the coordinates from the Paris to the Greenwich prime meridian

This defines a moderate extent of what is locally called the Ăhaggar (meaning the mountain range). Foucauld also records a separate name for the foothills of the mountains, which reinforces the understanding that Ăhaggar refers only to this highest mountainous area. The rocky or mountainous areas immediately adjacent, which may be geologically completely continuous, have separate Tuareg names. They are, then, not part of the Ăhaggar mountains according to local, traditional usage (as transmitted by Foucauld). At any rate, the peaks are much lower outside the Ăhaggar.

Regarding the name of the mountains, Foucauld states that …

Ăhaggar est le nom propre de cette région et le terme le plus employé de beaucoup pour la désigner

“Ăhaggar is the proper name of this region and the term most used by many [? most used by far?] to refer to it.”

He also lists a bunch of alternative names, and, as stated above and clearly on Foucauld’s mind when writing the gazetteer, Ăhaggar is at the same time the name of the country. Therefore he decides that …

pour éviter les confusions, nous la désignons habituellement dans ce dictionnaire non pas par le nom Ăhaggar, mais par le nom Ătakôr-n-Ăhaggar

”to avoid confusion, we [i.e. the author, Foucauld] usually refer to it [the massif of mountains] in this dictionary not by the name Ăhaggar, but by the name Ătakôr-n-Ăhaggar” – in effect, in almost all instances shortened to Ătakôr.

I think it is probable that by this decision, Foucauld started the European tradition of distinguishing a central part of the Ăhaggar as the Atakor – when, in fact, Foucauld makes it clear that in local usage these names are interchangeable and refer to the same mountain area.

The country

In a second entry, Foucauld states that Ăhaggar is also the name of the …

pays tout entier des Kel-Ăhaggar (territoire soumis à la domination des Kel-Ăhaggar, compris entre le Tidikelt, l’Ăhnet, l’Ădṛaṛ, l’Ăir et l’Ăjjer)

“The entire country of the Kel-Ăhaggar (territory under the rule of the Kel-Ăhaggar, surrounded by the Tidikelt, the Ăhnet, the Ădṛaṛ, the Ăir and the Ăjjer)”

With Kel-Ăhaggar being the …

[nom propre] des Touaregs qui habitent le territoire de l’Ăhaggar, en un seul corps de nation, sous le commandement d’un chef unique

“proper name of the Tuareg who live in the territory of the Ăhaggar, as a single body of a nation, under the government of a sole ruler”

I wouldn’t make claims about undivided nationhood – Foucauld’s statement stems from a specific political era and perspective, of course. The complex structure of Tuareg society is much better described in European scientific literature by now. Nevertheless, it seems appropriate to characterize the Ăhaggar as an independent, self-governed country prior to military defeat by the French in 1902.

As described by Foucauld, the Ăhaggar mountains are the center (not geometrically) of the Ăhaggar country, and the latter is named after the former. But the country stretches far beyond the mountains, about 500 km to the North, 330 km to the East, though only some 200 km West and 150 km South. It covers various landforms – mountains and sand seas and flat rocky areas, another major mountain range (the Tefedest), and even claims some of the surrounding sandstone plateaus.

As said above, I think the Ăhaggar is nowadays still perceived by inhabitants as a distinct region or land, after decades of being subsumed in Algeria. (Perhaps the term “cultural region” might be fitting?) The distinction seems clearest in relation to the largest neighbour, the Ăjjer. Ăhaggar people have clear opinions that things are done differently in the Ăjjer, and where necessary carefully delineate spheres of influence.

Foucauld sketched the borders of the country. This sketch can be seen on page 8 and page 9 of the scan of one of his dictionaries. As a work of Charles de Foucauld, this sketch is in the public domain, and I might get around to releasing my digitization of it.

The Ăhaggar in current databases

I’ve already introduced some of the understandings of names by Europeans; I’m going to quickly cover how and where they are present in online databases:

GeoNames

GeoNames has two entries for the mountains, Ahaggar and Atakor, showing the European distinction described above. The placement of both entries is in the correct area; however, as said before, both names refer to the same massif for local native speakers.

There is no entry in GeoNames to reflect the historical country, current region or land.

Wikidata

Wikidata also distinguishes between the Hoggar and the Atakor-n-Ahaggar. On the latter item, I have already added some of the information found in Foucauld’s gazetteer. The English and German Wikipedia articles linked to Atakor-n-Ahaggar imply, to my understanding, that the Atakor volcanic field is an area established as distinct in geology – and therefore could be treated as distinct from local naming and delineation. The Dutch Wikipedia article covers both the mountain massif (i.e. the indigenous concept) as well as the volcanic field (i.e. the scientific concept).

The French Wikipedia article describes the Ăhaggar mountains as covering 50000 km²; the English article states that the mountains cover 550000 km². The ellipsis based on Foucauld’s (approximative) description has an area of about 3600 km². Therefore, the Dutch Wikipedia article comes closest with 3800 km².

I don’t know of a Wikidata item for the country Ăhaggar – maybe I’ll create one when the existing ones are improved.

OpenStreetMap

OpenStreetMap has a node and a way to represent the Ăhaggar mountains. They are redundant to each other – they both describe the mountain range, without an obvious sign of the European Ăhaggar–Atakor distinction. (However, they link to the separate Wikidata entries.)

I have created the way, not too long ago. The node is much older. The way shows my best understanding of how the Ăhaggar mountains are delimited, starting from Foucauld’s (public domain) sketch map and refined according to a number of entries scattered throughout the gazetteer.

In my opinion, the two OSM objects could be merged to a single object representing the local conception that there is one mountain massif distinct from the surrounding areas interchangeably called Ăhaggar/Ătakôr (plus some other alternative names).

I’m not too keen on creating a boundary of the historically independent country, current region of Ăhaggar on OSM.

JOSM. Плагин RelToolBox. Практический пример использования: исправления болот в лесу

Posted by _PG_ on 31 May 2020 in Russian (Русский)

“Очень часто новички рисуют болото в лесу, не вычленяя эту территорию из территории леса. Потому что лес нарисован мультиполигоном, а работать с ними сложно. Получается, что у нас полигон болота залит поверх полигоном леса. Это некорректно. Записал демонстрацию работы по поиску и исправлению таких ошибок.”

Сделал ещё один видос, примерно на час с небольшим, с демонстрацией практической работы с инструментом reltoolbox. Демонстрация получилась так себе, потому что большую часть видео я тупил, пытаясь понять, на что же такое я в данный момент смотрю (как на зло, в ходе демонстрации попался для распутывания особо злобный клубок полигонов).

Mapping as Protest

Go on https://tar1090.adsbexchange.com/ past 8PM in your time zone. Find a helicopter in the air that is making an obscure amount of circles. Find out where it started at, then map the area.

This is fully nonviolent, does not require you to leave your house, although it probably would not change the status quo on it’s own.

Field names: lucky map find (Ireland)

Posted by b-unicycling on 29 May 2020 in English (English)

Luckily, I’m well connected with the right people (at least in this case), and people know my obsessions about benchmarks and field names. I had been surveying Cramersgrove in Co. Kilkenny and a friend said that “we” (in this case Kilkenny Archaeological Society) had a c 1815 Coghill Estate map in our archives with field names on it. Again luckily during lockdown, I have a key to the archives, because I was doing some work there at the beginning of lockdown, so I had a root around. The problem with those maps is that they are all rolled up and you don’t know what’s on them until they’re unrolled and not all of them are labelled. But I found the right one! And it does have field names on it and some match the ones I got from the farmer who lives there now. His great-grandfather must have been purchasing that land about the time that map was made. That should be well out of copyright and I should be allowed to add the historical names. If there is a tag…

The field with the pin is Bonnahilla on the 1816 map. A bit of a different spelling to Bawn na haille.

Utilizando Overpass no Python para gerar alertas para Gps Garmin

Posted by Tomio on 29 May 2020 in Brazilian Portuguese (Português do Brasil)

Como já comentei em outro post, faço alertas de Lombadas (ou quebra-molas) e também de Pedágios com os valores da tarifa, para Gps Garmin Automotivo. São distribuídos gratuitamente no fórum GpsClube.

Através de uma consulta overpass e edições no LibreOffice, crio um arquivo csv para utilizar no programa Poi Loader da Garmin, que compila os alertas (formato gpi).

Montar o arquivo csv demanda um certo tempo, então resolvi estudar Python para automatizar esta tarefa.

Assim, nasceram dois pequenos programas, muito rudimentares e básicos que fornecem o arquivo csv pronto para rodar no Poi Loader.

Para rodar os programas, utilizei a plataforma Colab, da Google:

Para facilitar a utilização e dispensar a instalação do python, transformei os dois programas em arquivos executáveis (.exe) para o sistema win10, com emprego do Auto-Py-to-Exe.

Fieldnames: don't forget HerStory

Posted by b-unicycling on 28 May 2020 in English (English)

It occured to me today that when “we” are out inquiring about field names from farmers, we usually only get the names on the farm we are on or maybe neighbouring farms. I think what is very important to consider is asking the wife in the house (if she’s not already the informant) about her homestead. It’s likely that she grew up on a farm as well. And she could be from some remote area that the surveyor (“we”) is not likely to get to any time soon.

Of course you have to be prepared for that eventuality. Going out to the farm with FieldPapers of that farm won’t be any use for the wife from further afield (pun not intended). Taking a laptop, praying for good broadband and using OSM there and then might be the better strategy. If she doesn’t remember, she might still have a brother or nephew on the home farm. Once the contact is established, a FieldPaper atlas could be sent to him. She will be able to explain it to him in their own words rather than in our mappers’ lingo.

This is all academic so far; I haven’t had a chance to try it. Yet.

Wandern mit OSM

Posted by Hungerburg on 28 May 2020 in German (Deutsch)

Wenn man auf Wanderungen Zufallsbekanntschaften macht und auf Nachfrage einen Blick auf die Wanderkarte werfen darf, dann sieht man in gar nicht wenigen Fällen ein Produkt das auf den Daten von openstreetmap.org (OSM) basiert. In der recht verbreiteten outdooractive Variante nimmt das freilich sehr Wunder, denn die Darstellung der OSM Daten, gerade was Wege angeht, ist darin derart reduziert, dass mehr als der Verlauf kaum ersichtlich wird.

Dabei enthalten die OSM Daten weitere hilfreiche Angaben dazu, die sich optisch ansprechend einbauen lassen. Einige Apps unabhängiger EntwicklerInnen, recht preiswert, manche sogar kostenlos, bringen sie ausdrucksvoll und schön zu Tage. Böse Zungen werden sagen, outdooractive (die gemanagte Community) oder Kompass (der Verlag) tun das absichtlich nicht, um ihren Zahlprodukten keine Konkurrenz zu machen. Andere werden sagen, die Daten sind nicht professionell genug auf einen Mindeststandard gehoben, um sich die Mühe anzutun, sie überhaupt in die Gestaltung zu übernehmen.

Wie dem auch sei, wer dagegen mit google-maps wandern geht, das wohl nicht nur meines Erachtens professionellste Produkt am Markt für Navigationssysteme, dem kann sowieso nicht geholfen werden, schließlich ist es für Leute gemacht, die mit ihren Füßen hauptsächlich ein Gaspedal bearbeiten oder zum Shopping durch eine Altstadt bummeln, und wirklich gut darin, hier von A nach B zu finden. Aber auch diese Karte bekommt man, zumindest wenn man nicht zu fern breiter Forststraßen unterwegs ist, hin und wieder zu sehen. Was man nicht im Kopf hat, das hat man in den Beinen, das kommt dabei heraus.

Was gibt es zu jenen OSM Daten nun Wissenswertes zu erzählen? Das Argument mangelnder Professionalität hat einen wahren Kern, die Daten entstehen, ähnlich wie Einträge in der allbekannten Wikipedia, zu einem nicht unbedeutenden Teil aus dem Fleiß von Hobbyisten, in diesem Fall Sonntagsgeographen unterschiedlichster Motivationen und Meriten. Penibel nach GPX, Luftbild und DGM eingetragene selten begangene Steige finden sich dort gleichauf Skiabfahrten mitten in der Sahara, die erstaunlich lange stehen bleiben, wohl weil den in ihrem Machtrausch kichernden Kids ob deren Absurdität niemand böse sein kann. Große Mengen Daten stammen aus open government data Beständen und sind häufig ohne viel Prüfung in Bausch und Bogen übernommen worden; angesichts des schieren Volumens nicht weiter verwunderlich.

Wenn ich in einem Werbetext lese, dass ich gegen Aufpreis in einer App amtlich beglaubigte Daten als Grundlage der Karte zukaufen kann, verstehe ich sofort, warum selbst Leute, die dieses Paket erworben haben es in der Praxis dann nicht verwenden. Schließlich will man ja den aktuellen Weg, dessen Zustand oder die zu erwartende Schwierigkeit erfahren und nicht, wo im Grundbuch ein Wegerecht hinterlegt ist oder wo vor 50 Jahren Jäger ihre Reviere durchstreiften.

Was man selten zu sehen bekommt, sind Karten auf Papier. Die Übersichtlichkeit bleibt nach wie vor unübertroffen, die Geschwindigkeit mit der man von der großräumigen Orientierung zum Detail wechseln kann detto. Aber die müsste man ja jedes Mal extra heraussuchen und auch einpacken.
