I've had a quick look, the houses are often low density and there are lots
of them which makes mapping a cluster awkward, it also means that marking a
tile done is difficult if any buildings are not mapped. The tracks / roads
can be difficult to pick out which again makes marking the tile done
Hi John
Yes, this is important to zoom in enough. This is a tropical country and there
is dense vegetation that sometimes partly obscure the buildings. In comparizon,
it is easier then to map for the Vanuatu islands where the vegetation is ever
more dense.
For these emergencies, the
Thanks for the responses guys.
I'll take a look and decide a course of action, which may include reworking
the task slightly. This is one of the first I did and I don't think I
realised the workload involved in such a large area.
Cheers

Hi all, I am doing some work on http://tasks.hotosm.org/project/836.
However, I am struggling to discern the direction of the waterways in this
square: http://tasks.hotosm.org/project/836#task/283
Is there any advice, tips, etc out there on how to work this out? If there

Hi Pete
From JOSM WMS/TMS preferences, the OpenCyclemap layer is available. It
provides elevation contour lines.
If you select this layer, it should help to see in which direction the
waterways flow. But not always easy to interpret.
Looking at the secondary highway at the bottom of this task
Given the resources available I think it would be better to reduce the
scope and first map major roads and say settlements of more than five
houses. If I look at what has been mapped a lot of individual buildings
have been mapped which is good but in the same time far more buildings
could have

Hi, Pete:
One of the main tricks I use for a first glimpse of the water flow
direction is zooming out the imagery. That way you will see the big
rivers and where their water goes to.
You can also check maps with hillshade layers, like the
