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.

Appraised value of land : 179,000/ m²

Appraised value of land : 1,290/ m²

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
