<font size=2 face="sans-serif">Eric,</font>
<br>
<br><font size=2 face="sans-serif">I like the map. I like it better than
the current recent earthquakes map. I feel people are more used to this
type of map than the current map interface we have.</font>
<br>
<br><font size=2 face="sans-serif">What do you mean by filter by MMI? would
this be the max MMI experience by XX people? or the MMI max derived from
ground motion prediction equations? I think max MMI experience by people
would be more interesting.</font>
<br>
<br><font size=2 face="sans-serif">Not sure what you mean by custom RSS
feed could you give example?</font>
<br>
<br><font size=2 face="sans-serif">The ability to go back beyond 7 days
would be nice.</font>
<br>
<br><font size=2 face="sans-serif">I agree with Dave that the zooming is
awkward. If after clicking a quake it stayed centered this problem might
go away.</font>
<br>
<br><font size=2 face="sans-serif">I also like the someone's previous suggestion
to be able to get a list of the quakes on the map.</font>
<br>
<br><font size=2 face="sans-serif">I worry about having another map interface
and hope this would replace the current version.</font>
<br>
<br><font size=2 face="sans-serif">nice map,</font>

<br><font size=2 color=#004080 face="Calibri">Hi Eric,</font>
<br><font size=2 color=#004080 face="Calibri"> </font>
<br><font size=2 color=#004080 face="Calibri">I also put these comments
on the web form.</font>
<br><font size=2 color=#004080 face="Calibri"> </font>
<br><font size=2 color=#004080 face="Calibri">If the map starts at the
global level, it's difficult (and very frustrating) to zoom into a scale
and region of interest. For example, to zoom into the San Francisco Bay
area region, one must either</font>
<br><font size=2 color=#004080 face="Calibri">a) use
the zoom slider bar, which is a guess as to the proper level. It’s clumsy
going from the globe to my target area.</font>
<br><font size=2 color=#004080 face="Calibri">b) repeatedly
alternate between the + zoom button and re-centering. That took me 30 seconds
to get to where I wanted (I timed it)</font>
<br><font size=2 color=#004080 face="Calibri">c) continue
to double click *off* the area of interest. If you double click on
the area, then you are likely to hit an earthquake, which pops open the
information balloon, but doesn't zoom in. If you double click away
from the earthquakes, then you miss your target and often get lost.</font>
<br><font size=2 color=#004080 face="Calibri">If we were to use this tool,
I'd like to see a number of standard entry points to get users to common
starting maps. Perhaps a hybrid system of the old fixed maps, and
a cookie system where users can preset at what level they want to see the
Google display. I’m not sure how that would work.</font>
<br><font size=2 color=#004080 face="Calibri"> </font>
<br><font size=2 color=#004080 face="Calibri">I have other concerns. It
seems that there is a real risk of getting in bed with Google for primary
information delivery. Has the USGS worked out an agreement with Google
regarding advertising? What about the competing "map" service
from Microsoft? </font>
<br><font size=2 color=#004080 face="Calibri"> </font>
<br><font size=2 color=#004080 face="Calibri">I recall that Barbara B did
a test with lots of earthquakes, and the map really bogged down. This
test didn't have many quakes on it (M>2.5). It is absolutely necessary
to be able to see quakes down to M1, because in aftershock sequences they
rapidly map out the rupture zone, or in volcanic sequences indicate changing
levels of unrest. In CA, the map is boring without all of the little quakes.
Moreover, many users just want to see all the quakes, regardless
of their motivation. This map interface must be able to smoothly handle
that level of information. For example, on the CA-NV map today, there
are 600 quakes/week. It could easily jump to 3000 quakes during a
volcanic sequence. Have things improved since Barbara did her test?</font>

<br><font size=3 face="Times New Roman">Below is a link to a proof of concept
mapping tool that plots recent earthquakes on a Google Map using the RSS
feed as a data source. This application isn't perfect but can serve as
a starting point for a more elaborate effort. Please take a moment to look
at this tool and also to fill out the feedback form about it so I can know
what people are thinking and how well the tool is working.</font>
<br><font size=3 face="Times New Roman"> </font>
<br><font size=3 face="Times New Roman">Because the RSS feeds aren't being
updated on EHPDevel, the data you see may be out of date, but this is driven
dynamically on the client side so if this goes into production we will
automatically get updated mapping assuming our RSS feeds are working (they
should be).</font>
