As far as you lead the operation and communicate regularly about this action, you should have support from the HOT contributors following this email list and reading the various hot.openstreetmap.org Blog updates. We can help you to create Task Manager jobs for remote mapping and invite contributors to participate.
Note that their are key factors for a constant participation of remote contributors to these actions. This is a technical and humanitarian community and we connect through internet and need to know each other, make interesting the volunteer participation. Communication about the objectives and the work done in the field is essential to motivate participants. This is also more fun and motivating for both the remote mappers and field contributors to build together such actions, discuss about methodology and progress, to feel that we are a global community and experimenting interesting new approaches. A broad community follows these discussions and are interested to learn how we build these actions and experiment themselves.
Good communications can be done both from this list and with some Blog updates with pictures. See for example an update about Lubumbashi http://hot.openstreetmap.org/updates/2014-04-01_a_week_in_lubumbashi_drc

Many thanks Pierre and Pete for your helpful suggestions. Much appreciated. We already started to draw the features using JOSM as much as possible. I would follow that methods used in Kamrangir char in last Missing Maps Project. Trying to collect some more GPS/androids. Lets see.
Would I get support from HOT (as in Kamrangir Char of Missing maps Project) to upload all the road and major features what will be collected initially by 1/2 GPS holder to track all possible roads and features ?

Ahasan, great news, man... Do the volunteers not have their own android phones. In the final days mapping hazaribagh and Kamrangirchar, they were using osmand on their own devices. Also, I think there might some gps units around that Jorieke left the previous time she was there.In addition to the tracing, the technique that worked well in Kamrangirchar was to send one mapper out for the day on a rickshaw, making sure they go down every road to the end. We gave them a gps unit and a a phone and used the combination of tracks to edit the road network (which HOT helped add) ahead of field mapping with surveys. This worked well there because tracing was hard due to the density of buildings.Good luck and look forward to hearing how it went....!PeteOn 9 Feb 2015 21:09, "Pierre Béland" <pierzenh at yahoo.fr> wrote:
We will be pleased to support you for this action.
I would suggest that you first organize a remote mapping session with your local experienced mappers, trace the map in detail (roads + buildings) and add as much infos as you can. This will greatly facilitate the field work later. There is good Bing and Mapbox imagery available. This should facilitate tracing buildings an roads.
Infos such as street, locality, neighbourhood names and important infrastructures such as hospitals, etc. will help later people to locate them when doing the field work.
We often prefer to use the JOSM editor since it is possible to work even in the context of bad internet connection. There is also a building plugin that facilitate tracing the buildings.
In the preparation of the Field work, it would help that you test your field work methodology, including adding the information to OSM later. While some people are mapping some areas, you could alternate and do some field work collection to test your methodology both using phones and paper. Since you only have 3 phones and 1 gps, it will be important to also use FieldPapers. Phones and gps could be used to trace streets and compare with the map made from aerial imagery. There are also questionnaires available that help document the infrastructures.1. Phone Android applications such as OsmAnd with an offline map do not require access to internet (If it was possible to have more phones it would help I think)
2. FieldPaper printouts where people can take notes.

Dear Jorieke/ Pete and all,Hope you are fine. I would like to inform you that we (WSP-World Bank) collaboration with CARE Bangladesh has intended to map (house hold level) an union of Nilphamari District named Botlagari starting from end of this month. Though in the OSM data this remote area almost blank. Do you have any suggestion what might help me to finish this union in a easiest way ?. FYI, this union have almos 9000 households. We will have 16 trained local mappers and we have 3 androids and 1 GPS. Looking for your urgent suggestions:
Please see the union in below umap link: https://umap.openstreetmap.fr/en/map/botlagari-union-of-sayedpur-upazila-of-nilphamari-_28405#13/25.8052/88.8945
