[HOT] Fwd: Accuracy ( international women's day)

Hi guys, just to add my tuppence worth...


When we use field papers, we find it really useful to use them in conjunction with OSMAnd. The data you see is the same on the phone and the paper and so, using the gps locator on the phone, points recorded on field papers are that much more accurate.


You can even display your feel paper grid over the map in OSMand (it's a bit fiddly, but not too hard). Details, here: http://wiki.openstreetmap.org/wiki/Field_Papers#How_to_use_with_OsmAnd


Hope that helps...


Pete

Field Papers is a web-based tool for easily creating a printable map atlas for anywhere in the world that you can print and add notes to. It is one way to edit ...

Hi Russ,

Thank you for your feedback. We are going to map water sources such as taps, Solid waste dumping areas and toilets. But The houses are not so spaced. That is why I was asking The best method that can give us accurancy.

No problem Gertrude – happy to know I was on the right topic :)

That is a bit of comparing apples to oranges, you will probably want to use both. I don’t use OSMtracker myself, so not sure the specifics, but if it’s using cell tower location vs. GPS, then it may not be very good in Zambia and will depend on how many cell towers, signal strength, etc. If it uses the phone’s GPS (if it has one) then you should be ok.  Field papers is very ‘low-tech’ – basically you’re sketching on a map which you can then upload to trace/edit from – so it’s only as good as the person drawing. You might also think about taking pictures to either use in JOSM, or you can check out Mapillary (https://www.mapillary.com/) so you can have a picture/visual when you get back to the office for editing.

In general, I would suggest a workflow such as:
- Trace as much ahead of time remotely/using imagery – having major roads, bigger/landmark buildings will help navigate/use Field Papers
- Have as many people with OSMtracker or a GPS, etc. recording their tracks – great for getting roads, etc.
- Have other people with Field Papers, Mobile collection apps, etc. marking things like business details (things hard/impossible to see from overhead) and taking pictures

Then when you go to edit you should use all of the available data to make the best map!

Most importantly, have fun!

Hi Russ,

Thank you for getting back. We are going to map in The field and some people questioned The accuracy of OSMtracker for it is what we are going tp use.

Which is more accurate between fieldpapers and OSMtracker?

Hi Gertrude,

I am not quite sure what kind of ‘accuracy tools’ you’re asking about.  It sounds like you will be mapping in the field? If so, GPS units are going to be your best bet (unless you have access to professional survey equipment).  We often supply our field missions with Garmin Etrex-20 units (http://sites.garmin.com/en-US/etrex/). We also often employ field papers to go along with/in-replacement of GPS (http://fieldpapers.org/).

There are also many mobile applications for survey/field-data-collection, I think this is a good place to start: http://wiki.openstreetmap.org/wiki/Software#Mobile_Devices

Let me know if that’s not what you’re asking,
=Russ

We are orgainising an event on 8th March women's Day in Zambia. We would like to know The best tool that can give us accuracy, Cause we are going to map sanitation I.e toilets, water taps and waste in a slum Where The plots and toilets are close to each other.

Thank you
