<x-tab> </x-tab>ONE:<br>
<x-tab> </x-tab>Because we
don't know for sure if these structures are houses, we just tag them as
"Building." Something the size of a house could be Siddharta's
Car Repair, so we're safest with "Building."<br><br>
<x-tab> </x-tab>TWO:<br>
<x-tab> </x-tab>Could be a
huge boulder, but, if it's rectangular, that's unlikely. Most likely, if
it's square or rectangular, it's a building. Also, if you look for
shadows along the edge, sometimes you can see that it's about one story
tall and has a straight roofline.<br><br>
<x-tab> </x-tab>THREE<br>
<x-tab> </x-tab>I doubt
there are many triangular buildings. Yes, change those.<br><br>
<x-tab> </x-tab>FOUR<br>
<x-tab> </x-tab>Try to do
the exact building shape. That makes it easier for field teams to match
actual buildings to the map. It can be a challenge if the building has a
couple of wings and a porch, but it is helpful.<br><br>
<x-tab> </x-tab>FIVE<br>
<x-tab> </x-tab>Yes,
please add the individual buildings within the "residential"
polygon. <br><br>
<x-tab> </x-tab>SIX<br>
<x-tab> </x-tab>Most of
the Bing images are not after the earthquake. Some imagery is recent,
notably that marked DigitalGlobe, but I'm not sure if it is after the
earthquake. Can anyone else answer this question?<br><br>
<x-tab> </x-tab>Thanks for
all your hard work.<br><br>

<blockquote type=cite class=cite cite=""><b>ONE Small
structures/houses</b> <br>
In remote areas, lightly populated, it's difficult to see if a small
structure is a house or something else. I am labeling them all
"house". Is this correct? People live in tiny places in Nepal,
less that 25' square. They are hard to discern. If it looks like a
building, I mark it as a house. Is this good? <br>
<b>TWO Geologic structures<br>
</b>It is difficult to tell geologic structures from houses in some
cases. I look to see if there are similar structures in the landscape, if
there are fields or agriculture, then mark it as a house as I have been
erring on the side of marking houses and having people recognized as
being there than not. I want everyone on the map. This may mean I've made
mistakes and it's a huge boulder with a shadow. Comments? <br>
<b>THREE Changing others' work<br>
</b>Also, some of my colleagues have marked houses with triangles, not
rectangles. Can I correct these? <br>
<b>FOUR Exact building shape<br>
</b>Is the shape of the building important? It's often difficult to tell
if it's part of the house or an outbuilding or a shed near the house.
Knowing there are people living there seems more important, but if the
actual shape is important, I will go back and redo my work. <br>
<b>FIVE Residential vs. all houses marked<br>
</b>Many remote villages are simply marked with a polygon Residential
Area. Should I add the structures to these areas? <br>
<b>SIX Up-to-date BING images?<br>
</b>Also, how recent are the Bing images? In remote areas, much could
have been lost to landslides. I also come across areas with clouds. I can
go back and map these if the images are refreshed. <br>
