<br><font size=2 face="sans-serif">It's critical that you change your extents
to match the data you want to show.</font>
<br><font size=2 face="sans-serif">For example, I've built an application
that shows all the Great Lakes (Canada-USA) in a 'lat-long' coordinate
system.</font>
<br><font size=2 face="sans-serif">In my map file, I've defined the extents
as:</font>
<br>
<br><font size=2 face="Courier New">EXTENT -93 38 -74 51 #xmin ymin
xmax ymax NAD 83</font><font size=2 face="sans-serif"><br>
</font>
<br><font size=2 face="sans-serif">If my shapefile is not in this extent
(like a shapefile of India), I will not see it.</font>
<br>
<br><font size=2 face="sans-serif">Also, you don't have to define a projection
in your map file, as long as all your input datasets have the same spatial
reference.</font>
<br><font size=2 face="sans-serif">If you plan to reproject on the fly,
then you will have to define this parameter.</font>

<br><font size=2><tt>Hi All,<br>
<br>
I'm a new user of MapLab-2.2.I belongs to India.<br>
<br>
I have created a map file named "test.map". where i want to add
india<br>
as a layer.I'm getting every thing correct(Like legend bar,scale<br>
bar,tools etc) but not getting any view on the map extent.<br>
<br>
My shape file is not in any projection system .This is simply geo-referenced.<br>
<br>
Also i'm not providing any projection system for this.have i to define
it??<br>
<br>
I have taken the Map extents as it was in the tutorial map file .Have<br>
i to change this as per the geo-graphic location(though i don't think<br>
so).<br>
<br>
Any-thing wrong am i doing??Kindly tell me the procedure to correct it.<br>
<br>
Thanks to all in advance for the supports.<br>
<br>
