[ncl-talk] About shapefiles

[Mary Haley]

Soares,

I will help you one more time on this problem. You need to read and
understand the emails and scripts I've sent you, rather then just emailing
me for more help. You must LOOK AT YOUR DATA before you randomly start
adding city names to your "majorCities" list.

I've showed you multiple times how to do this.

I've created an NCL script that reads every string variable off the
TLS_adm2.shp shapefile, and searches for the cities you listed.  I didn't
find any cities called "Cristo Rei" or "Nain Feto" anywhere any of the
shapefiles.  I even searched for just "Nain" and "Feto" and didn't see
anything.

See the attached script, which you can run yourself.

-----------------------------------------------------------------------------------------------------------
I had typed the below before I created the "examine_tls_adm.ncl" script.
This information is potentially useful for future purposes, so I decided to
include it. This explains in more detail how to use "ncl_filedump" and
"grep" on the UNIX command line to examine a file for the cities you want:

For example, if you are trying to find out if there's a city called
"Metinaro" in the "NAME_2" variable, then type this command:

   ncl_filedump -v NAME_2 TLS_adm2.shp | grep "Metinaro"

When I type the above command, I get the following output, which indicates
that this city is indeed in the list:

Metinaro

However, if I try to search  for "Nain Feto":

   ncl_filedump -v NAME_2 TLS_adm2.shp | grep "Nain Feto"

The UNIX prompt comes back without any output. This means it did NOT find
"Nain Feto" in the list.

I then tried:

   ncl_filedump -v NAME_2 TLS_adm2.shp | grep "Nain"
and:

   ncl_filedump -v NAME_2 TLS_adm2.shp | grep "Feto"
These both came back empty, which means you CANNOT use "Nain Feto" in your
"majorCities" variable.

I was then curious about whether there were ANY cities that actually start
with the letter "N", so I did this:

  ncl_filedump -v NAME_2 TLS_adm2.shp | grep "^N"

The "^" is a special character that means to match something that starts
with this letter.  The only city that starts with an "N" is "Nitibe".

I then wanted to see if any part of the NAME_2 cities has an "F" in it:

ncl_filedump -v NAME_2 TLS_adm2.shp | grep "F"

This gave me:

Fatu Fulic
Fatu Mean
Fohorem
Fato Berliu

Hopefully you can see where I'm going with this.  You MUST figure out the
exact name of the cities before you start putting them in your
"majorCities" variable.
