[Opengrads-devel] shape.gex: almost ready for release

[Arlindo da S. <da...@al...>]

Graziano,
1)  I applied a patch this weekend and it now correctly displays shapefiles
even when the domain is [0,360]. So, I believe we have something ready for
people to try out. The code is checked in, give it a try. Preliminary
documentation is here:

    http://opengrads.org/doc/udxt/shape/

2) For the sake of completeness I'd like to prepare a suplemental
*.shapedata.tar.gz with several freely available files of interest:

admin98,shp - is there anything more recent than this?

gshhs: land, lakes, ponds and islands within lakes; these may be very useful
for people preparing navigation charts (I know of a couple of users in this
category)

3) Do you know of any shapefile for the major global rivers? Or any other
shapefile of interest. How about major world highways? Very useful for air
quality studies - pollution is usually found around major interstates)

4) Having these sample shapefiles we should be able to have a comprehensive
set of examples for the documentation.

5) Having these files installed under GADDIR, I was thinking about adding
the following UDCs:

shp_map     (same as shp_lines $GADDIR/admin98.shp)
shp_bmap   (same as shp_polyf $GADDIR/admin98.shp - replacement for
basemap.gs)
shp_land     (shp_lines $GADDIR/gshhs_land)
shp_lakes    (shp_lines $GADDIR/gshhs_lakes)
shp_pond    (shp_lines $GADDIR/gshhs_pond)
shp_isl         (shp_lines $GADDIR/gshhs_isl)

shp_rivers (???)
shp_roads (???)

The idea is to create a very easy to use package, while retaining all the
flexibility with the shp_polyf/shp_lines commands.

6) I'll save the "shp_print" command for the next release (it will remain a
stub for now).

  Let me know what you think,

     Arlindo
