Re: [HOT] West African HOT Mapping Tips
Hi John, We have talked about making them more widely available and we do include them in some of the W. Africa instructions or pass them out to mappers individually, sometimes as part of validation feedback. I have a short list of revisions is partly why I have not moved them out from my personal page yet in the wiki and called them done As to the huts: It can go either way, but it is my understanding we usually try and map the building footprints as it provides just a little bit more data, approximate size and can help when working physically on ground for orienting yourself a little better than just a point on a map. But it is up to the project manager to determine what data they need v. how fast it can be generated. In one circumstance just getting a building count and structures represented on the map quickly could be a lot more important than whatever else we gain by an actual building footprint. And sometimes the circumstances of mapping affecting things. If you are working in the field on a smart phone collecting building locations off line and entering data for each building, outlines would be impossible. As to drawing the huts quickly, you might already know these things in JOSM, but just in case: When you copy/paste, where you hold the cursor will be the center of the pasted object. So hold your mouse pointer directly in the center of the hut to paste. Then with the newly pasted building selected, hold control-alt keys down and you can resize the object you just pasted based on the center of the pasted object. That lets you quickly get the pasted hut the correct size.

Re: [HOT] West African HOT Mapping Tips
Tangentially, some of us have been working a system to make it easy to publish guides. Still in process, and no instructions. But I think this could be a great place to host Blake's guidelines on West Africa, as well as tips on huts. http://hotosm.github.io/tracing-guides/guide/kulna.html https://github.com/hotosm/tracing-guides/ http://hotosm.github.io/tracing-guides/ -Mikel * Mikel Maron * +14152835207 @mikel s:mikelmaron On Saturday, March 14, 2015 7:36 AM, john whelan jwhelan0...@gmail.com wrote: Could the link https://wiki.openstreetmap.org/wiki/User:Bgirardot/West_African_HOT_Mapping_Tips be added to the instructions of all HOT West African projects?

Re: [HOT] West African HOT Mapping Tips
Hi Severin, I can share all the originals ( I think/hope I still have them ). That was my main mistake, the text on the images making the translation difficult. It was a process and you can see in later items the text came out of the images and went into the caption to make translation easier. That is also the style Nick has implemented in LearnOSM: Numbered arrows for detail and clarity in the illustration, and then text explaining the details of the illustration and they look great. As to the videos: I also have a few of those, not silent unfortunately :) But I have recently thought about doing short animated gif illustrations and passed around the Training WG email list a few tools that do that well. Here is an example of tutorial with animated gifs that used something like the tools I passed around to the Training WG. This example is busy ... maybe a bit too crowded for all the activity on the page, but gives a good idea of what someone can do with short animations for tutorials. Laid out better like Mikel's example of Bangladesh mapping and it could be very educational and low bandwidth. https://www.mapbox.com/blog/mapillary-mapping/ Cheers, Blake On 3/14/2015 2:05 PM, Severin Menard wrote: Hi Blake, This is a great tuto, would it be possible to share the original pics for translations?
