World Map Coordinates!

[Stephen R McMillan]

Francesco,
I have no experience using the downloaded lat/lon files with GrADS'
basemap function, nor transforming to .asc files. Instead, I have used a
simple script to read the lat/lon coordinates, then draw the map
boundaries using the "set line" and "draw line" functions. So, after
drawing a base map (if needed), I run the script to draw the new map
information, then plot my gridded data.

Hi Steve. I visit the site you have posted and I  downloaded the lat/lon
file for Italy. How can I use this file with the basemap  function of
GRADS? How can I transform this file into a .asc file? Do you have  an
application to do this?

Thanks in advance.

Vinoj,
Try this web site: http://www.maproom.psu.edu/dcw/.  Although some of the
political boundaries may be out of date, It provides a  downloadable
lat-lon text file ("download points" option) which you could then  read
into a GrADS application. If you have further questions, let me  know.

Dear da Francis,

I am glad to  receive ur reply to my query on the grads list...

Infact I need the world coordinates for all the countries... not  just
India.
For the moment, it will be sufficient even if i can get the  exact details
(lat
lon) of the land and ocean boundaries... I shall make do  with whatever
analysis i do right now.

Moreover Is it possible to readout the GrADS hires map  dataset?

Hope ur stay out there at NY is  fine...
shall get back to u off list...

regards,
Vinoj V
