Wikimania, the annual Wikim(p)edia conference, took place just over a week ago. On Friday, August 5, we gave an OSM workshop and then took ~25 people out onto the streets of Haifa for a mapping party. We split into several groups, each led by experienced mappers (seav, uip, Zvika, Yarl, Polimerek, and myself) and accompanied by Hebrew speakers.

Yesterday afternoon, I was in Bethesda, Maryland, just outside of DC, for a meeting, parking six blocks away. The meeting happened to be at the same place (Caribou Coffee) where we met for an OSM mapping party in November 2009. (osm.wiki/Bethesda_Mapping_Party) At that time, we collected some POIs for the area north of the coffee shop.

This time, I got POIs for the main shopping area to the south of Caribou. Between Mazpen POI Collector app and jotting down some notes, I collected & added ~100 pois while walking. Also, there were some things to update. (new Taylor Gourmet, Vapiano; Austin Grill and some other places gone now)

Since then, I've filled in nearly all of the buildings in Bethesda, using aerial imagery and the map looks completely transformed.

There's still lots more to do, collecting more pois, addresses, and other details from on-the-ground mapping, and maybe another mapping party. ;)

Digital Capital Week (http://www.digitalcapitalweek.org/) starts this weekend, and runs all next week, featuring numerous tech events in Washington DC. There also are a number of projects going on during DCWEEK, including one to map shops and other POIs in DC.

We are taking this as an opportunity to focus on neighborhoods that are not well-mapped yet. This includes the up-and-coming area around H St NE. On Sunday, we will meet from 11am - 3:30 pm at the H St Pop-up Lab (Library kiosk) at 1300 H St NE and do some mapping around there.

During next week, if there is interest, people could get together in the evening and do mapping in other neighborhoods that are not so well mapped (e.g. Capitol Hill, U St / Logan Circle).

With the data, we would like to create a custom map that highlights shops and other places in DC.

After DCWEEK, there still will be plenty left to map around DC, but we hope to make a noticeable improvement on Sunday and next week and increase interest in OpenStreetMap.

Details are on the DCWEEK wiki, as well as sign-up: http://bit.ly/cYq4Xz

I did some cleanup in OpenStreetMap, around the National Mall in DC. Some parks data from DCGIS had been imported, but there were duplicates with what was already in OSM. In looking at the map after my cleanup, I noticed something quite odd. "Vietnam Memorial" is written with the "memorial" part upside down. I didn't realize that Mapnik writes labels upside down.

In edit mode, I saw that the Vietnam Memorial was drawn as a polygon and tagged with just a name. Also, the Constitution Avenue label is cut off and shows it as just "Constitu". I went in and tagged the Vietnam Memorial as tourism=attraction and historic=memorial. Now it renders as an area and seems labeled properly, offset from the polygon and right side up.

Though I am not sure the walkways are correct and need to check them with a visit. There is plenty more to do with both data imports and collecting details around the mall.

We had approximately ten people at the Silver Spring mapping party last Saturday. This was the first for the new Mapping DC group, following on from a mapping party in June that was organized by CloudMade (now former) community ambassador Russ Nelson.

We are focusing on areas surrounding DC proper, as the DC government has shown willingness to allow us to import their GIS data. That's not the case for surrounding jurisdictions such as Montgomery County, Maryland.

My slice of the "cake" was the area between (south) of the railroad tracks and the DC border. I added the buildings along East-West Highway, including the NOAA buildings. I also added the Falkland Chase apartment complex and the Blair apartment complex -- both which occupy an entire square block with numerous individual apartment buildings and shops. Behind the Falkland Chase apartments was a small park, with a creek, walking paths, and an off-lease dog area.

Near the Mayorga coffee shop where we met, there is a brand new apartment building (The Veridian). When mapping this, the Yahoo! imagery was uselessly way out of date. Blair Mill Road used to cut through from Georgia Avenue to East-West Highway. The road has been reconfigured as Blair Mill Way, and does not connect with the rest of Blair Mill Road on the south side of East-West Highway. I got this change and the new building into OSM. I notice that Google Maps is still outdated with the old Blair Mill Road.

I'm not done with making edits to my area, and other people are still working on theirs. But, here are images that show before and after:

I'm new to OpenStreetMap, though not new to mapping/GIS and am a long-time Wikipedian. I got a GPS unit about a month ago and took it with me to the State of the Map conference in Amsterdam.

Afterwards, I spent some time in Belgium. I had some idea that Europe was well-mapped in OSM, but noticed Oostende (along the coast) was poorly mapped. So, I spent a bit of time walking along the beach and around town doing some mapping. I mapped numerous streets, along with the walking paths in Leopold II Park.

In the past few days, I finally got around to uploading my traces and mapping them. I tried using JOSM, though my computer is not new and JOSM is unusable. I can use other Java applications just fine, like NASA WorldWind. I had also looked at Potlatch previously and was not terribly impressed, though looked again and noticed improvements. :) Potlatch works for viewing and mapping my traces, though I think further improvements are still needed along with other good tools.
