[Talk-ca] Qu�bec wiki page
I just revamped the Québec wiki page and called it Portail OpenStreetMap pour le Québec. I wanted to have a more attractive page and structure the information so that It's easier to follow. See http://wiki.openstreetmap.org/wiki/Canada:Québec There was a lot of stuff related to the road network. And the Route Verte bicycle network was not specified on that page. Also, I started to create a Page for Sentier de l'Estrie, a 200km hiking trail in Eastern Townships. And created relations for the various sections of the trail. I used more attractive presentation, displaced road network stuff in a new page and created three pages related to routes (ie. road, bicycle and hiking). I plan to add to the contents of these pages, the rules to create Relation routes. As you can see in the Sentiers de randonnée pédestre page, I listed the relations related to Sentier de l'Estrie hiking trail network, wich facilitates the follow-up. LISTES DE SUIVI Réseau routier du Québec Itinéraires, Pistes cyclables Sentiers de randonnée pédestre Sentier de L'Estrie http://wiki.openstreetmap.org/wiki/Canada:Qu%C3%A9bec/Sentier_de_l%27Estrie In this page, you will find hyperlinks to HikeBikeMap and Lonvia maps. I have made rendering test using osmc:symbol tag developped by Lonvia and used in Europe. This is a work in progress. The sections are not all documented yet and I will also add the secondary trails connecting to this main trail. I started from GPS traces already in OSM and discussed with Sentier de L'Estrie club to present the complete network. We will meet in january on that matter. I am member of that club wich should faciliate it. You can Look at the maps below to see how the Route relations render on maps. If you make your own rendering tests, you should note that these maps are updated daily. The info on your relation will be copied at 00:00 (Switzerland time). You will see the result the next morning. It remembers me the time when I had two shots a day using keypunched cards.

[Talk-ht] Propositions for more efficient Nominatims searches and consistent classification of cities, towns, villages and hamlets of Haiti for better rendering on maps
I have passed a long time searching, correcting town names, try to validate if Health units where located at the right place. This made me realize how many city names where still missing or inconsitently classified for Nominatim searches or Map rendering. Except for the boundary relations for each levels of the Administrative structure of Haiti, I have not seen propositions about how to classify the different villages, towns and cities of Haiti. And looking at the map of Haïti, I have have seen a lot of inconsistencies. The towns corresponding to Administrative levels Department, Arrondissement and Commune where not seen properly on the map or could not be searched properly in Nominatim. And some hamlets, peaks or simply names in haiti-tlm-50 corresponding to no housing where classified like important cities. An other example is Search for Gros Morne. Search was indicating Gros Morne peak but not Arrondissement Gros Morrne. I started to correct things in Nord-Ouest and Artibonite Departments and modified the various tags to see the effect on Map rendering. The Wiki page http://fr.wikipedia.org/wiki/Haiti presents the Administrative levels of Haiti and estimated population of 2008. From that, I propose the following guidelines : Boundary Relations To facilite Nominatim searches, I propose to modify the Boundary Relations by adding in the name tag a suffix that represents the administrative level (ie. Département, Arrondissement, Commune). If you make a Nominatim search, you will see the effect of this. Try (Arrondissement, Haiti) or (Gros Morne). You will also see thats it facilitate the search for people trying to see administrative level boundaries. Artibonite Department boundary relation would show : tag k='admin_level' v='4'/ tag k='boundary' v='administrative'/ tag k='name' v='Département Artibonite'/ tag k='pcode:1' v='5'/ tag k='type' v='boundary'/ Dessalines Arrondissement boundary relation would show : tag k='admin_level' v='5'/ tag k='boundary' v='administrative'/ tag k='name' v='Arrondissement Dessalines'/ tag k='type' v='boundary'/ Gonaïves Commune boundary relation would show : tag k='admin_level' v='8'/ tag k='boundary' v='administrative'/ tag k='id_commune' v='511'/ tag k='name' v='Gonaïves'/ tag k='pcode:2' v='511'/ tag k='source' v='US Census Bureau, boundary import, 16/01/2010'/ tag k='type' v='boundary'/ tag k='addr:country' v='HT' / tag k='admin_level' v='8' / tag k='alt_name:en' v='Gonaïves' / tag k='is_in:Department' v='Artibonite' / tag k='is_in:country' v='Haiti' / tag k='name' v='Gonaives' / tag k='name:fr' v='Les Gonaïves' / tag k='name:ht' v='Gonayiv' / tag k='population' v='263716'/ tag k='pcode:2' v='511' / tag k='place' v='city' / tag k='source' v='http://fr.wikipedia.org/wiki/Les_Gona%C3%AFves' / Town nodes For towns representing the administrative levels 4. Département, 5. Arrondissement and 8. Commune, I propose to add systematically the Population tag indicating population size (The info is provided in http://fr.wikipedia.org/wiki/Haiti for each Administrative level). The Tags place=city (pop 100,000+) and place=town (10,000 - 100,000) should be reserved to cities corresponding to Département, Arrondissement and Commune. The Tag place=village should be reserved for Sections communales (Administrative level=10). All other places should be classified place=hamlet. When homonyms exist like Gros Morne, it seems that searches are more efficient in Nominatim when adding the tags addr:country=HT and is_in='The superior Administrative Level'. In this case, all the homonyms will be showed while searching for that name. Polygons for Residential areas These polygons when they are to important gives some confusion. I wonder if we should systematiqually avoid using them for hamlets (towns other than Département, Arrondissement, Commune or Section communale).

Re: [Talk-ca] Rendering Island names in OSM
Richard Weait wrote Dear Pierre, You can make suggestions for changes to the existing rendering styles. And you can make your own rendering style for your own use. http://help.openstreetmap.org/questions/1107/can-i-influence-what-gets-rendered-in-the-main-mapnik-layer Richard, This is more general than how I would like to render my individual map. I think that it refers to the general tagging schema of Openstreetmap for entities such as island and lakes. If you look at Liberty island in the port of New-York. You see that, with Mapnik, the name of the island is well rendered at zoom level 13. The name is ever bigger than the island. For the Great Lakes, also, we cannot see the names on the OSM maps. Thats bring more questions. Are they any tags that could permit a certain hierarchisation for rendering of entities like we have for city names? Is this non representation of entities like Great Lakes or important island is a choice that have been clearly expressed in the Openstreetmap community? If not, in wich instance, should we discuss about that? PierreB ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca

Re: [Talk-ht] Haiti: extended high res imagery, hurricane Tomas, and cholera
On the Haiti Earthquake Map page (http://hyperquad.telascience.org/haiti3/), it is possible to select many layers simultaneously to show adjacent tiles. The resolution of these tiles is generally very good. I can go up to zoom=18. Below is the rule to show these maps with JOSM wms tool, where LAYERS = name of the layers to show, If more than one layer is requested to show simultaneously adjacent Map Tiles, the Layer Names are separeted by a comma).

Re: [Talk-ht] River system analysis tool for Haiti
Jean-Guilhem The cholera epidemy and water contamination shows the importance of well identifying the Drainage Bassins in Haiti. These like a tree leaf, have complex ramifications not easy to analyze. I am not a GIS specialist and dont know if specialized tools exist to analyse such ramifications. Here are some observations following the validation work I did manually last spring on Haiti Rivers, streams and canals. The affluents of a river are complex ramifications. See, for example, http://www.openstreetmap.org/?lat=18.4057lon=-72.0741zoom=14layers=M . In such a ramification, its long and tedious to check each ramification, to validate if directions are appropriate. To this regard, the Report http://osm3.crans.org/haiti/suivi-affluents.php shows only small part of Drainage bassins. To analyse and build good cartography of Drainage bassins, we have to consider all the waterways and all ways and nodes connected to. I have identified waterways with the following tags : river, stream, canal and drain. I have often seen ways with the wrong direction (going upward). Yan report on rivers also shows many small waterway segments not connected to a Drainage Bassin. We have to consider the possibility that ways are connected to a River ramification with wrong tags or are wrongly connected to rivers. Ideally, we would have to analyse more deeply the river ramifications and identify different incoherencies, check if all river names are present. If useful to identify steep slopes, it could also be possible to add elevation to each node. To do efficiently the validation work, it would be necessary to extract all the nodes and ways connected to river ways and relations. And badly, that, I dont know how to do with Openstreetmap database. If it was possible to easily export all the information related to rivers in a MySQL database, I think that we could do a lot of validations from that database. In Yan List of Rivers (http://www.tappenbeck.net/osm/data4wiki/haiti/haiti-river_wiki.html ), there are still many unnamed segments. Many of them might be unconnected to other rivers. This list have to be manually updated and might have not been updated recently. Opencyclemap contour lines could be usefull to identify river directions. But rivers are not showed on that map. I dont know if there are ways to add simultaneously contour layers and river layers to Openstreetmap. Exemples of problems Canal Desdunes (waterway=canal) not connected page http://www.openstreetmap.org/?lat=19.2867lon=-72.5855zoom=14layers=M Many River ramifications not connected http://www.openstreetmap.org/?lat=18.4397lon=-71.9705zoom=14layers=M A stream connected to a road http://www.openstreetmap.org/?lat=18.4579lon=-71.8602zoom=14layers=M Rivers ending nowhere (or in canals ?) in suburb of Port-au-Prince http://www.openstreetmap.org/?lat=18.5218lon=-72.125zoom=13layers=M When looking at zoom level 13,14, you will see well the ramifications and see a lot of problems with orphan rivers.

(I have just learned how to add a relation as member of another relation in JOSM: - double click the tributary relation in the relations panel, it should appear in pink in the main editing area; - single click the destination relation; - click on the Modify relation button). It is also considered to maybe adapt the page http://osm3.crans.org/haiti/pyramide-cours-eau.php?osm_id=48998245 (originally authored by Sly, and currently using ways only, not relations) to build the network from topology information and display it in a table.
