The advanced settings dialogue box provides you with extra
tools to search the atlas files.
International
Atlas
In the International atlas as it stands, the advanced settings
feature has a very limited usefulness. This is because feature
types are not used consistently or widely in the source data from
GNS. The advanced settings feature was added
to Astrolog32 mainly for future expansion.
First
Search Field
There are three search fields currently defined. The first one
is the type of place name. The majority of place names is of type
"native", meaning in the language of the country. About 20% or so
of the names are "variants". These could for example be alternate
spellings of the same name, or different forms of the name. As
example, "Adlershof" appears as a native name, and also as the
variant "Berlin-Adlershof". The reason is that it is a
neighbourhood of Berlin.
There are also non-verified names, meaning that there is a
doubt about them, and finally "conventional" names, which are names
of a place in a non-native language, for example "Lisbon" or
"Lissabon" which are the English and German "conventional" names
for the Portuguese city of Lisboa ("native" name).
Second
Search Field
The second search field is the type of populated place. Ten
types are defined. The most common by very far is the type
"unclassified". Types of interest are the "Seat of first order
administrative region", which will enable you to find the most
important towns, and "Capital of a political entity", for example,
Paris is the capital of France.
These types of populated places are quite strange to say the
least, and are not used consistently, but that is the way they are
in the source data from GNS. For details go to the GNS web site.
There is no point in complaining about this to the Astrolog32
designers!
Third
Search Field
The third and last search field is the classification
according to the population. 97 % of the places are unclassified.
This field is for future expansion, in case GNS starts using it
more. In any case, class 1 would group the most populous towns in
the country, and class 5 the least populated villages. Note that
population classes are relative, that is a town of 100 000 could be
class 1 in a country of low population, and class 3 in another of
high population.
How to
use Search Fields for searching places
To search for a place of a given type, tick the corresponding
box. By default all boxes are ticked. There are buttons to select
and de-select all types of a search field. Note that search fields
are used in addition to the initial letters, as extra requirements.
For example, if you want to find all the main towns whose name
starts with an 'A', enter 'A' or 'a' as the initial letter in the
main atlas dialogue box, and as type of populated place select only
"Seat of first order administrative region". Also note that search
fields have no effect on browsing by blocks.
Your selections for advanced settings are not saved in the
configuration file, but are remembered by the program while it is
still running, going back to the default (all types selected) the
next time you run the program.
Search
Fields in the list of place names
In the list box of place names in the main atlas dialogue box,
names are displayed in the following format:
Name | Region % Search Fields population @ longitude
latitude
Search Fields are always a three character code, the first
character being the first field as defined above (type of name),
the second character the second field (type of place), and the
third character the third field (class of place).
In our previous example we had:
Clifden | Galway % N-- @ 10w01 53n29
The search fields "N--" then indicate it is a "native"
name, of type "unclassified" and population class
"unclassified".
The advanced settings dialogue box, besides providing a way to
select types, also offers a legend on the different types. You will
see at the end of each type a character in brackets, for example,
"Native [N]". This means that 'N' in the first field indicates the
name is "native", etc.

How to
use Search Fields for searching places
To search for a feature of a given type, tick the
corresponding box. By default all boxes are ticked. There are
buttons to select and de-select all types of features. Note that
the search field is used in addition to the initial letters, as
extra requirements. For example, if you want to find all the
churches and temples whose name starts with an 'A', enter 'A' or
'a' as the initial letter in the main atlas dialogue box, and as
type of populated place select only "Churches, ...". Also note that
search fields have no effect on browsing by blocks.
Your selections for advanced settings are not saved in the
configuration file, but are remembered by the program while it is
still running, going back to the default (all types selected) the
next time you run the program.
Search
Fields in the list of place names
In the list box of place names in the main atlas dialogue box,
names are displayed in the following format:
Feature Name | Cell Name | County
Name % Search field @ longitude latitude
The search field is a three character code. The
advanced settings dialogue box offers a legend on the different
types of features, as three characters inside brackets
after the description of each feature type, for example,
"Cities, towns, villages, etc [ppl]". "ppl", which stands for
"populated places", will be shown in the names box for all names of
towns and villages.
