This area which is
marked on the map is
quite close to the optimal
one.
Actually, It’s hard to
distinguish it without the
red circle because it’s a
very limited area.
As you see, most of the
bad sites are located on a
steep slope or some of
places are just beside
mountain streams.
[Left side of worst place] [right side of worst place]
There are country housing sites below the best place.

1. Convenience
- The optimal area is
located on a main street
of the town.
- There is a supermarket,
a bus-stop and senior
citizen’s centre just
behind the optimum.
2. area
- 4 houses on the
area in the past.
- So, If you are willing to
build a garden-housing
there, It will be enough
size for 2 houses.
3. Position
- A wide panorama &
Plenty of sunshine
- Not that far from the
city centre by a
private car.
4. Differences
- The optimum is near
the local people’s
living area comparing
with the garden-
housings which are
located in down town.
5. Transportation
- It’s difficult to get this
area if you haven’t got
own your car.
• So, It would be the best choice to build a country house in the best place.
• GIS is very convenient compared to the field survey. It can save time, money.
• GIS provide very objective, accurate data
• GIS can conclude many kinds of data• GIS is very practical study, so this can
be used very widely.• Google Earth, GPS, Navigation
-> Close relation to our real life
