Hello,<br>
<br>
Has anyone created a new set of *.asc files for <a href="http://basemap.gs" target="_blank">basemap.gs</a> to add state<br>
and provincial boundaries for countries outside of North America? The<br>
default files do not contain these political boundaries. It appears new<br>
polygons can be added to the *.asc files, but please let me know if<br>
somebody has already done this.<br>
</blockquote><div><br>If you are using GrADS v1.9.0-rc1, Graziano Giuliani has contributed a shapefile extension that allows you to use any publicly available shapefiles for providing maps backgroung and the like. For example,<br>
<br>ga-> set mpdraw off<br>ga-> d ts<br>ga-> shp_lines admin98<br><br>or<br><br>ga-> shp_polyf admin98<br><br>Where "admin98" is the ESRI First Level

<pre> <a href="http://geodata.grid.unep.ch/download/admin98_li_shp.zip">http://geodata.grid.unep.ch/download/admin98_li_shp.zip</a></pre>See sample plots attached. The documentation is here:<br><br> <a href="http://opengrads.org/doc/udxt/shape/">http://opengrads.org/doc/udxt/shape/</a><br>
<br>Besides continentatl lines one should be able to plot a varity of shapefiles, including lakes, islands, even highways. There are all kinds of shapefiles freely available on the web, and no file conversion is necessary.<br>
<br> Please contact me directly if you are interested in beta-testing this extension. Keep in mind that this extension does not yet work with GrADS v2.<br><br> Arlindo<br></div></div><br>-- <br>Arlindo da Silva<br><a href="mailto:dasilva@alum.mit.edu">dasilva@alum.mit.edu</a>
