== Lösung der Aufgabe ==

=== Animadversion on the given table ===
# Absolutley no fill color
# No subdivisions i.e. loan type (there are only 2 types) or term (also 2 types). The information adjustable/fixed or 15/30 is used too often.
# The table is sorted by points. Maybe it would be better, if it´s sort by rate or term
# The word ‘mortgage’ is used to often in the column ‘lender’, it´s not necessary to repeat it so often
# In the column ‘points’ the numbers should have the same amount of digits before and after the decimal point
# The numbers in the column ‘rate’ should all have 3 digits after the decimal point
# The title “effective September 1, 2003” isn´t clear. Is this a date or something else? (because only 1,2003 is bold, why is september not bold?)
# Due to the use of white spaces the reader scans the table column by column but it would make more sense, if there is less white space between the columns but more white space between the rows. This would make it easier to read the table row by row.
=== The improved table ===
This table is the right one, if the value "points" is very important (for more details please go to "The improved table v2" below).

'''Why is this table better than the original one?'''
* It's primary sorted by points.
* It's easier to follow one row, because of smart use of whitespace.
* All numbers are aligned to the left
* Now every Number of Rate has 3 digits on the right side of the decimal point
* "Mortgage" is not in every row but once in the header.
* We broke up the table in 2 parts: the "fixed" one and the "adjustable" one. This gives you a faster overview of your possibilites if you're going to lend money.

=== The improved table v2 ===
We were not sure, what the value "points" is. In the first version (above) we sorted the table by points, because it's also sorted by points in the original one. But afterwards we thought, that the value "points" is not so important, maybe it's just the commission. If it is so, it doesn't make sense to sort the table by commission. So we created a new version of the table (this version is better, if "points" is not important).

'''Why is this table better than the original one?'''
* It's sorted by Rate, which is the most important value if you're going to lend money.
* It's easier to follow one row, because of smart use of whitespace.
* The values are grouped together by points and terms, so you don't need to fill in the same values for points and terms in every row.
* The Rate and all numbers are aligned to the right -> you can compare it easier.
* "Mortgage" is not in every row but once in the header.
* We broke up the table in 2 parts: the "fixed" one and the "adjustable" one. This gives you a faster overview of your possibilites if you're going to lend money.
* The "lender" value is centered, because every lender is represented by exactly 3 characters - it's easier to follow.
* We used an unobtrusive grey rule to delineate the header from the body.

= Generalization =
Generalization is the abstraction of aspects of the reality, which is important for a special kind if question. A field of use is the visualization of maps.
==Definition==
A. Hettner defines Generalization as 
„… a selection of the most important, the essence and the target-oriented simplification. In this process, it is important that the map shows the most important, characteristically attributes, which are needed for the use, the topic and the scale of the map.“

== Overview ==
It depends on the scale, which information can be shown on a map. The designer of a printed map can decide, which information is shown (i.e. toponyomies, name of the streets, rivers…) and on which position within the map this information should be placed. But digital maps aren´t produced in traditional way. Users can zoom within these maps. It depends on the zoom-factor, which information is shown. The computer has to decide, which information is shown on which position. For this procedure algorithms are needed.

== Goals of generalization ==
# Improve the message of the map
# Improve the communication of the content of the map
# Improve the speed of the collection of data
# Help to find answers on questions
# The shown information should be useful for the target-audience (i.e. maps for traffic-engineers, city-engineers, environment-engineers…)

== When should be generalized? ==
# If a map has too much information. Then it´s hard to understand the information (i.e. different symbols, Overlapping of symbols, colors…)
# If a map is designed only for a special audience and only a special conclusion is needed
# If information could be combined
# If maps lose their character because there are too much of information
# If important information is unnoticed
# If objects are too small, if they are shown in „correct“ scale

== Kinds of generalization? ==
# Simplifications (i.e. defines of shapes)
# Straighten (i.e. curve)
# Aggregation (i.e. arrangement of objects)
# Combination (z. B. important information overlap less important information)
# Union (i.e. many objects are combined to one)
# Change the symbols (i.e. from shape-symbols to point-symbols)

== Examples ==

All 3 figures show the same segment of the map 
Figure 1 shows the most details. The shapes of the buildings are not simplified yet. This map doesn´t show the main-street. 
Figure 2 shows with the color yellow the main-street. The shapes of the building are simplified (only rectangles are shown). The quantity of the buildings is not equal with the “real” quantity. 
Figure 3 doesn´t show details like some streets or the little river on the bottom-left side. The building in the middle is now presented with a flag. This visualization doesn´t represent the reality, but it increases the important of the building 
Figure 4 shows more examples of generalization
