DOCUMENTATION

Goal of software
---------------------------
This software finds possible georeferencing errors 
in the
datak.xls placenames file of the Bernstein Paper Atlas 
(http://www.bernstein.oeaw.ac.at/). It is intended as a 
development support tool for georeferencing.

Software species
---------------------------
Written in MATLAB Version 7.4 (R2007a), Mapping Toolbox 
Version 2.5 (R2007a). Standalone for Windows XP. Uses
the unicode-read.m file to read Unicode data.

Data file structure
---------------------------
The data file to be debuged should have the following structure: 
placename, latitude, longitude, NUTS region code (if omitted 
outliers won't be processed).

A sample dataset (with and without NUTS codes) is provided,
together with the debuging output files.

Elements of the window
---------------------------

Types of errors to identify:
1. Variants: same placenames and same coordinates
2. Focus: same placenames with slightly different coordinates
3. Homonyms: same placenames with sizeable different coordinates
4. Proximity: different placenames, but very close coordinates
5. Outliers: coordinates outside a given region
6. Precision: rounding coordinates to a given number of decimals

Outliers requirement
---------------------------
The availability of this option depends on wherever a file 
containing the boundary information and called "nuts.mat" is 
present.

The Matlab file should have the following structure.
nuts.nuts0
nuts.nuts1
nuts.nuts2
nuts.nuts3
nuts.nuts0.name - NUTS0 names
nuts.nuts0.longitude - longitude coordinates vectors
nuts.nuts0.latitude - latitude coordinates vectors
nuts.nuts0.id - NUTS0 code
idem for nuts1 to 3
