<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>a)
Include data in either UTM or Lyon County Coordinates – including the
ability to utilize the LMIC WMS Server which is in UTM. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>b)
Have the XY location on the bottom of the map to display Lyon County
Coordinates, the latitude and longitude must be accurate for the pictometry
tool. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Currently
my data is in UTM so that it matches the LMIC imagery. The XY location of
also is in UTM. The highway department expressed interest in having the
XY location display in County Coordinates. To fix this, I changed the
Coordinate system in the .js file from UTM to MN-COUNTY LYON. The XY
location did display our county coordinates and the measurements were correct;
however, the latitude and longitude are no longer valid.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I
would like to keep using the LMIC UTM image server, however, we do need the XY
location in county coordinates and the latitude and longitude to be
correct. The GIS data could be in county coordinates or UTM. For my
own curiosity I would like to know how to get the county coordinates to work, I
also think it might save time dealing with updates – and yes I understand
that there will be a performance hit if mapserver reprojects on the fly,
however I can always switch back if I think its too slow. Perhaps someone
could send me a .map file using county coordinates as an example.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I agree with Jim, I would put all your data in Lyon County cords
and then reproject the LMIC WMS on the fly to county cords. I have an
example mapfile of doing this exact thing for another county if you want it,
just let me know.<o:p></o:p></span></p>

Issue<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Next,
I am having some issues with the extent. What I would like to do is
display only a portion of the data by using a top bottom left right box area
instead of a query. However when I assign to small of an area the entire
layer does not draw. Can I use the extent to limit the displayed area, or
is this not possible?<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I don’t believe this is possible, at least not that I can
think of a way to do it with MapServer or GeoMOOSE. I would just clip
your data set, it will perform better any way.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>

by Buffer<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>On
the select by buffer tool I noticed that If I typed in a ridicules number such
as “buffer parcels within 900 miles” The server obviously could not
handle the request and crashed. Is there a way to limit the buffer size?<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>We do have the capability of specifying a form validation on an
input parameter, but I’m afraid it is undocumented and has never been
tried with the buffer tool. You could always right your own javascript to
do this, but you would need to dig into the GeoMOOSE code for that.<o:p></o:p></span></p>

<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>We
need the ability for some users to log in to get access to more secure
data. For example a we need a public and internal site or perhaps one
where users log in i.e. The Sheriff might want a “crime map”
whereas only the sheriff and deputies have access to that information.
Does anyone have any ideas on how this could be done though geomoose?<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I do this all the time for clients. It is not a feature of
GeoMOOSE or MapServer. Rather it is handled in the server admin side of
things. If your running IIS you can use the windows authentication to
restrict people to a folder or file. You can also do that same thing with
Apache using the httpd.conf file.<o:p></o:p></span></p>
