I think Lake Faguibine in Mali should be restored.

If you can read French, there was recently a discussion about that on talk-fr : http://gis.19327.n5.nabble.com/region-de-Kidal-au-nord-du-Mali-td5746516.html#a5746885 - there are certainly more, but I recalled this one.

London Congestion Charging

Of course, tagging the “zone” as an area means that navigation tools will need to be area-aware - or that the Openstreetmap extract they use will require post-processing to tag any way within the area.

London Congestion Charging

It is a “zone”… So why doesn’t any of the proposed modeling scheme in osm.wiki/London_Congestion_Charge represent it as such, using an area ? Wouldn’t that be simpler than tagging ways ?

Neophyte

Let’s say it is an Openstreetmap blog for those who don’t have an Openstreetmap blog…

Southeastern New Mexico

If you want a snappy editing environment, use JOSM : http://josm.openstreetmap.de - may be a bit overwhelming in the beginning, but you get used to it you won’t want anything else… I have been using it for three years and I’m still from time to time finding tricks to speed up my mapping.

Yesterday I was despairing over a place where there are seemingly more contributors feeding that proprietary monster precious data that they will never be able to use as they see fit… So I’m glad to see that at least some of them are coming to the free world !

Wierd stuff with the rendering

Even when marking tiles as dirty, coastline rendering is a special case due to the huge size of the natural=coastline ways : coastlines are created using shapefiles generated from the natural=coastline ways by the Coastline Error Checker - that does not happen as often as normal Mapnik rendering, so the coastline’s rendering might remain out of date for a long time while the rendering of other objects has already been updated.

Cleaning Up GPS Traces for OpenStreetMap and Visualizations

No amount of automated processing will get rid of the scribble effect, but a simple manual edit will solve the problem : just cut the trace at the arrival point and delete the whole heap of spaghetti. Same with all the places where the GPS bearer has halted and produced a small heap of spaghetti. I usually do that sort of processing with Viking, but JOSM is fine too.

As for the segment with lost signal : delete it and split the way in two parts.

Mapping Trees in Gulu, Uganda

Good idea - better coordinate than do that on my own. I’ll think about it - that’s a plan for later this year.

Mapping Trees in Gulu, Uganda

I’m specifically interested in Arua - in Uganda too (osm.org/go/wjK7iywV-). I have friends there and I would love to do the armchair mapping and then see if they are interested in contributing names and POI. I’m tempted to buy a tile of decent imagery as an humanitarian gesture : http://tsms.terraserver.com/?img_key=E5B54A39-7C35-4058-A799-1B8EEECC6E64 - this 3500x3500 pixels georeferenced JPEG would cost $145… But I’m not sure it would do much good to map just the town and not have imagery even good enough for the regional road network.

Mapping Trees in Gulu, Uganda

Did you buy the Digitalglobe Geoeye imagery for Gulu ? I would love to have it for Arua - it is in great need of armchair mapping !

The world smallest mapserver?

Does your username have anything to do with your server’s physical shape being a cube ?

Relance de la cartographie en Afrique

Le problème de Google Map Maker est que la license ne permet que des usages très restreints, sous contrôle très strict de Google. Mieux vaut s'investir dans OpenStreetMap que de jouer le métayer de Google... Même si les images Google sont tentantes.

Pour renforcer l'appropriation des outils par la population et lui en proposer de plus pertinents, il me semble qu'il faut commencer par en comprendre les besoins... Et mes a-priori d'étranger sont une très mauvaise base de travail - et c'est là qu'au-delà de la cartographie tes connaissances locales peuvent fournir de bonnes idées, même sans aller jusqu'à une étude de marché complète.

Entre les ONG, le gouvernement, les entreprises et la population il y a sûrement des usages potentiels encore inconnus. Du côté de Map Kibera, il semble que rien que l'impact psychologique de l'appropriation de l'espace par la cartographie a été un facteur important d'adhésion.

Relance de la cartographie en Afrique

Très peu au Burkina - mes amis Burkinabés y vont rarement et je n'ai donc pas pu en tirer grand chose. L'imagerie Bing haute résolution est malheureusement peu disponible en dehors de Ouagadougou, ce qui rend difficile la cartographie distante. Mais j'aime bien cartographier l'Afrique - ça fait longtemps que je n'y suis pas allé et ça me manque alors, à défaut de voyager physiquement, les cartes sont un moyen de s'y plonger de temps en temps.

J'ai l'impression qu'en dehors d'initiatives humanitaires telles que Map Kibera, de nombreux contributeurs d'OpenStreetMap en Afrique sont des ex-touristes comme moi qui aiment les jolies cartes. Connais-tu des exemples locaux d'utilisation des données au delà du simple amour de l'art ?

Relance de la cartographie en Afrique

Tu connais Imasgo ? C'est le village de la mère de ma femme - c'est comme ça que j'en suis venu à l'ajouter dans OSM. J'espère y passer un de ces jours mais en attendant vive l'imagerie satellite et les commentaires des locaux dont je recueille les commentaires ! Tu es basé au Burkina ?

Google Maps guilty in France of abusing the dominant position of its mapping service

Offrir gratuitement un produit vendu par d'autres n'est pas illégal. Ce serait du dumping s'il s'agissait d'une vente à perte, en particulier si elle était manifestement destinée à couler les concurrents et si les pertes sur ce marché étaient financées par des profits réalisés sur un marché où l'entreprise domine. Cette définition ne s'applique aucunement à OSM. OSM ne distord pas non plus la concurrence car les données publiées sont offertes à tous aux mêmes conditions, sans aucune discrimination - toute entreprise peut profiter des données libres. La combinaison du but non lucratif de l'association et des conditions ouvertes de la licence est la garantie contre le risque de dérive vers l'abus de position dominante.

How to deal with dirt roads?

Richard's "highway=tertiary, surface=unpaved | gravel | dirt | what-have-you" is the correct answer. Here in Europe we are not used to anything but pavement, whereas in Africa I have often seen tertiary and even secondary dirt roads. The place of the road in the network hierarchy is the primary indicator for the highway tag - road surface is less important.

Wimbledon update

@pieren : leisure=pitch, sport=tennis, surface=whatever

Clay, hard and grass are the main surface types cited at http://en.wikipedia.org/wiki/Tennis#Surface

Wimbledon update

By the way, in the illustration in this post, is that one or two tennis courts ? I map that as two adjacent courts, but is one single court acceptable too ?

The White House uses OpenStreetMap

On osm-talk, Pieren reminded us that Whitehouse.org using Cloudmade osm maps has been announced on this list on the 5th March 09...That was news to me and apparently to a few others. Anyway, sorry for the re-post... I only searched current news and neglected to look deeper in the archives - I couldn't imagine this had been going on for so long !
