| Gzip for compressing planets | Interesting.... there's another compressor you could try 'LZO' which is intended to be fast on the decompress side. After all the planets are a compress once, decompress many scheme. Most of these compression algorithms spend some time computing the best 'dictionary' to use. Since the planets contain pretty much the same data is it possible to force a pre-defined 'dictionary' into the compressor to speed it up? |

| Henley-on-Thames, Oxfordshire | Looking really good..... You might want to check the one-way stuff down by Mill Meadows though (unless you guys have started driving on the right). Mungewell. |

| Hi, new member | Hi Bobby,
Depending on what you want included you can download graphics from the 'export' tab, or download the map data and render the image to your liking. There are some 'directions' websites and applications. If you require this to work in an offline mode, I suggest you look at Gosmore (osm.wiki/Gosmore). Cheers,

| Comin along nicely | Here's to putting ourselves on the Map!! Good job,

| Clarification on what I'm looking for in terms of audio mapping | I wrote this up and put on the Audio Mapping discussion page, if you can confirm that it works I'll promote it to the main page. Cheers,

| Clarification on what I'm looking for in terms of audio mapping | Whoops that GPX file didn't show all the tags... must have been stripped rather than escaped. :-( Regarding the accuracy of the timestamps, the recordings might be made on a system (laptop?) with NTP hooked into the GPS receiver's 1PPS output. They could be very accurate. Munge. |

| Clarification on what I'm looking for in terms of audio mapping | Whilst you are waiting for JOSM to be improved.... --
print strftime("%M:%S", $1 - first_time), $2;
$ find . -name '*.wav' -exec stat --format='%Z %n' {} \; | sort -n | awk -F ' ' -f strip_times.awk > events.txt $ cat events.txt
This should be passed to GPS event sync, which will produce a GPX output something like
-- If I remember correctly JOSM will play the audio contained in waypoints if the 'name' marker is replaced with 'link'. Have fun,

| Adding <link> tags to GPX? | PS. Should have noted that the timestamps will be a little off, problably when recording finished and care has to be taken when copying files around. If you use a application like Manauton (also listed) you can embed a click-track into the audio (which would not suffer these problems) and do neat stuff like negative latency. I was working on getting a scheme together, but haven't fixed my car's bearings yet so it's far too noisy to use audio mapping at present. |
|
| Adding <link> tags to GPX? | There's already a fair bit listed at:
I'd suggest looking at 'Gps Event Sync' which converts a listing to GPX waypoints. With a bit of script foo you can magically make the listing from file time stamps. If I remember correctly JOSM can play audio file linked to in those waypoints. Mungewell. |

| 3 month cycling, mapping, programming in SE Asia | Three months in (well 'on') the saddle! Have a great trip and stay safe,

|
| Mapping rural areas | Pretty much the situation in rural Canada, only the distances are larger. You just have to keep mapping.... Great news that the GeoBase data (for Canada) will be usable and imported in good time. |

| Mapping Tofino... Garmin Map Points | Hi,
I also started making a list of what was supported on my mono eTrex Vista
I believe the adding of names/phone numbers/etc is dependent on the map-creation software you are using. Mkgmap seems to just pick up the osm.wiki/Tag:'name=' tag, even to the extent that unnamed points appear as blank in the POI listings. Cheers,

| Node gluttony for areas | On thing not mentioned in routing.... If an area is of a suitable type then it could be used for routing, such as walking across a park or via a parking area. This 'use the same nodes' approach would have to take care to ensure that the whole shared boundary is indeed routable, and does not contain a boundary such as a fence. Maybe careful placement of shared nodes would be able to indicate entry points to a park. That said I am in favour of this approach as it produces neater looking maps. |

| First map update | These two links may help:
Happy mapping,
|
|
| Can I help? New to OSM | It basically boils down to lat/long position (elevation is stripped as nominaly not accurate enough with consumer units). 1 second data is useful, as it helps routers calculate travel time etc.... What equipment are you using?

| campus | There are already several application which will combine a GPS trace with digital photos, using the time stamps in the photo to interpolate a location. The location is then stored as an Exif tag, so that it can be used by JoSM, Flickr, or whoever. Personally I use my cellphone camera as the time on the phone is tied to real/gps time via the network, so I don't need to work out the difference. There are also projects to pick up time stamps on audio streams in a similar manner, see:

|
| Sidney, BC Seaside Route | You have two ways ontop of each other, one which looks like a GPS track multiple walks up and down should be removed (select way and 'shift + delete') the other looks good. I 'fixed' a few things in the relation to give you an idea of where to go with that... Mungewell. PS. Is that a pier? Everyone loves a pier, add a way and tag 'man_made=pier'. |
|
| Further mapping down towards Wallingford | Oh, the old stomping ground..... Don't forget the Hamlet of Mongewell ;-) Cheers. |

| Mapnik / Osmarender difference | Hi,
You can prompt a re-render from http://informationfreeway.org/ select the area at zoom 8 or zoom 12 and press 'r'. Cheers,
