Just learning how to use this program, having some difficulties. Wish me luck please!
So i like geography so for art class I learned the GPS sensor.
when i went on a road trip for spring break during spring break, I left my gps on and stored the values into sqlite database from the phone.
I then created a dataset of latitude, longitude, and time into 540,127 rows that I wish to use to create a visualization.
Today I worked on this project and borrowed a fast computer at the school, converted the rows from terminal sqlite query to (.txt and .html) form.
I am learning to program with Android for the course and so I found myself at the Google for fusion tables. About one hour ago I was able to figure out how to embed 100,000 (is limit on free acount?) onto the Google Map interface.
However, I want to do more and I hope Someone can offer me some advise or ideas.
Thank you for taking the time to read my story,

After joining this community, making my first edit, and getting some nice welcome messages, I found that my password no longer worked for some reason. I got very busy at work and kept putting off coming back until today as I'm pretty much changing ALL of my passwords due to the Heartbleed bug.
Now that I'm back in, I've made several updates to Crestline, California and some of the surrounding communities. While most of these were entries for restaurants and other businesses, I did find one incorrect piece of mapping in the Valley of Enchantment where Log Lane was shown to stop short of meeting the town's main drag, Waters Drive (for any fans of "Star Trek: Enterprise," the "Carbon Creek" episode from the second season did some filming on Waters).
It looks like a lot of this area has not had a lot of contribution as far as businesses go so I am glad to get back in here and add a few things for everybody. It's a nice place to visit so I hope my additions will encourage people to come up here...and, bring money...our local businesses need it! ;-)
If you for chance read my previous diary entry, I registered on GiveIt100 and documented with a video a changeset made each day in a different country. I followed some basic criteria: each day in a different continent (counterclockwise order); if I missed a day I'd map in the same continent for two days; map in a country where I didn't map before.
So, straight from January 1st, I got to April 10th and in the last video I did a changeset in San Mateo, CA, where lives the developer of GiveIt100 (I previously mapped in USA, I know!).
The complete project is visible on https://giveit100.com/@sabas/ro277m
Having the NaturalEarth shapefile half filled, I should paint it green completely some time...
Someone with a planet file at hand could do a ladder of users ranked by how many countries has been visited (similar to the hydc user page)..
Thanks to Karen and Finbarr for their work!
I cannot help but share two images of a place I stumbled over today while mapping a little. A decaying house with a half collapsed outhouse at its side - but some flowers were well attended:
JOSM seems to get translated at transifex and launchpad, you can file bugs against JOSM at josm.openstreetmap.de and github, you can file bug against a lot of OSM things at trac.osm.org and github, too.
It doesn't matter when all resources are handled equally, but it is not so nice when you look at the wrong place…
(unedited except for formatting. hopefully these will mean something in the future)

I'm presently targeting things that have inappropriate 'layer' entries in my area.e.g.
highway, layer -5 ... no tunnel/covered etc ...
park layer -2
I assume this way done for rendering issues. The areas look to be best served with multipolygons.
There do not appear to be tools to find these inappropriate layers, so I'm using a simple text editor to find them., then JOSM to do the editing.
Edited residential and houses in Dingle Iloilo, Philippines.
Problems with image resolution. Maybe some landuses are wrong, ask for criteria.

Over at Telenav we have been busy comparing the GPS traces of drivers using our navigation apps against OSM data. This is fun work and sometimes leads to really useful results. One of our recent studies involved comparing what we think are one-way streets to the corresponding OSM ways. The process is quite simple: count how many traces following a given street go in one direction, and how many go in the other. If the number for one direction is close to zero, the street is probably one-way. The outcome depends on the confidence level you apply, but it turns out that there are more than 100 thousand OSM ways that probably should be marked with a oneway tag, but aren't.
One. Hundred. Thousand.
I don't know about you, but I think that would make for a really great MapRoulette challenge. So that's what I did, and here it is.
But how do you know if a street should be one-way without having eyes on the ground? It turns out the aerial imagery provides helpful hints. Let me show you what I look at to verify the one-way-ness of a street using just JOSM and the Bing layer.
Let's look at this case here:
Notice the arrowhead? That is the direction we found the vast majority of trips followed, so we think that is the one-way direction of this street. Let's look in JOSM:
In this case, there is really only one hint that this is in fact a one way street, but it's a pretty convincing one: The markings on the road. See the stop line? It goes all the way across, which it wouldn't if traffic were allowed to enter from the right. Also, it is a little blurry, but there is what appears to be a left arrow painted on the road as well. So all in all, I am convinced that this way should be marked oneway=yes.
Be careful though! OSM ways can be very long, and the one-way restriction may not apply to the entire way. So always be sure to check the entire length of the way before you tag and upload, and split the way as necessary! The Telenav detection works on smaller segments internally, so the suggested one-way-ness does not always apply to the entire OSM way.
Lets' look at another case.
Looks like a residential area. Let's load it up in JOSM:
In this case, it's really hard to see. There's no obvious stopping line that I could see, and there's too much shade to see if there are parked cars on the left side of the street that are parked facing west - which would be another good indication that it is a one-way street, because it is illegal in the United States to park in the opposite direction of the flow of traffic. So this one I would mark as 'Couldn't See'. Perhaps someone else sees something I don't? Here is the permalink to the task in MapRoulette. (Neat eh, permalinks - makes it easy to share a task you want to discuss or highlight. They remain valid even after a task is fixed or even deleted.)
Oh and yes, I am afraid this is another United States only challenge... We are working hard to get more international challenges in, and we already have some interest. I am sure I mentioned this before, but MapRoulette now has an API that lets 'third parties' submit their own challenges. On top of that, we're also making it really easy to deploy your own MapRoulette server. If you're interested in any of that, just let me know. I will be hosting a session on MapRoulette at State Of The Map US this weekend, and Serge and are also planning to run a BoF session for a deeper dive into MapRoulette challenge making. If you don't make it to SOTM US, don't feel left out - there will likely also be MapRoulette sessions at SOTM EU in June!
Hal Hudson from New Scientist wrote a great article on how OpenStreetMap helps Médicins Sans Frontières (MSF) fight Ebola in Guinea:
WHEN doctors working for Médecins Sans Frontières (MSF) arrived in the West African nation of Guinea last month to combat an outbreak of the deadly Ebola haemorrhagic fever, they found themselves working in an information vacuum.
MSF enlisted the help of the Humanitarian OpenStreetMap team (HOT) and within a few days, a huge number of mappers flocked to OpenStreetMap, putting the affected areas on the map. Where existing Bing imagery was not sufficient, Astrium and DigitalGlobe provided fresh takes.
Even if this crisis is not in all the medias, the contribution from the OSM contributors is fantastic. In 8.5 days, 302 contributors, 1.2 million objects, 114,000 buildings, 5,000 places and 6,100 landuse polygons.
The New Scientist article explains how OpenStreetMap helps fight the virus:
Mathieu Soupart, who leads technical support for MSF operations, says his organisation started using the maps right away to pinpoint where infected people were coming from and work out how the virus, which had killed 95 people in Guinea when New Scientist went to press, is spreading. "Having very detailed maps with most of the buildings is very important, especially when working door to door, house by house," he says. The maps also let MSF chase down rumours of infection in surrounding hamlets, allowing them to find their way through unfamiliar terrain.
Since the response to the Haiti earthquake we are now seeing time and again how OpenStreetMap is facilitating incredibly mapping of badly needed geo data, helping first line emergency responders do their work.
You can't do this with any other map but OpenStreetMap.
This type of massive mapping effort is only possible because of OpenStreetMap allowing direct editing of data to anyone and the availability of OpenStreetMap as raw and open data. The former allows anyone to get involved in helping respond to a crisis, the latter gives full power to responding parties over how exactly maps should look like or access to raw data for analysis. No other map offers this level of openness at a global scale.

Effective immediately the Mapbox Satellite option in iD and JOSM is 100% open for tracing in OpenStreetMap, including all our high resolution DigitalGlobe imagery. This is full coverage down to zoom level 19 imagery in the US + Western Europe and world wide to zoom level 17.
To use this imagery select "Mapbox Satellite" from the imagery menu in iD on the web or in JOSM. Mapbox Satellite is open for tracing in OpenStreetMap in general and not tied to a specific editor, so if you would like to add Mapbox Satellite to another OpenStreetMap editor you are welcome to do so.
This is a big affirmation of DigitalGlobe's commitment to provide imagery for OpenStreetMap (also Bing imagery contains to a very large degree DigitalGlobe material). Props to Kevin Bullock and our friends at DigitalGlobe - it's fantastic working with good people who see wins of working with OpenStreetMap.
Editing in Washington DC with the Mapbox Satellite layer
PS - on an existing installation of JOSM you'll have to refresh your imagery menu like so: http://cl.ly/image/383O2L0t431s
I'm interested in helping OSM to start towards some kind of street view like service, which seems eminantly doable now that Androids standard camera app, allows for super easy taking of panoramic, full spherical style images.
Just having some trouble figuring out the most effective place to upload these?
- Theres opentrailmap.org, but then they only seem to want off road paths, parks etc.
- There's openlinkmap, but they only seem to be looking at adding this functionality at some time and even then they don't seem to have anywhere to upload the images
- there's openstreetview.org which looks promising, but as though it's been dead for years. Really this is the kind of thing I'm looking for, but is there anything more active?
- Then there seems to be some discussion about adding to OSM directly with the tags image=File:example.jpg and image:panorama=yes where example.jpg is your file uploaded to wikimediacommons. This looks like the most logical and promising, but will anywhere actually display these? the image tag is also marked as controversial, so will it stick around?
So where would you think to add street level, "Street View" style images into OSM so they're most likely to be useful?
Rimbo Bujang Give me everything.......Thanks !

I'm still having grief with bus routes again. I'm beginning to doubt whether it's worth doing at all. Where I live, there are several related bus routes with lots of commonality but also lots of exceptions. They run over each other's partial routes and self-cross all the time.
Doing one such bus route is bad enough, but trying to maintain a load of related ones is a nightmare.
I naively thought that I could take one route, copy/paste it as another relation and just change the different bits. Copy/paste doesn't work really well in JOSM. I only seem to be able to reliably copy/paste to a "new" relation, which means that the relation-id of a route effectively keeps changing.
I'm now trying to download the XML, make changes manually and re-upload them. However, downloading a relation contains all sorts of other crap, such as "author","timestamp","revision", which I can't sensibly copy into a new relation.
Nobody really supports super-relations, so the only sane way is to keep dependent routes in sync manually. How do other people do this?
