Abstruct
1. Determination of the forest boundary on LANDSAT data.
a. Correspondence method of LANDSAT data on earth surface.
That is necessary to correspond LANDSAT data on earth surface in each
pixel unit at the area of complicated natural features also forest
vegetation types. We investigated the most effective corresponding
method in nallow forest area as follow diagramme in Table 1.
As the results on this work the correlation coefficient of total pixels
in a compartment of CCT out put and compertment area was r=0.93.
Then the real correspondence accuracy in earch surface was limited inner
1 plixel replacement.
b. The relation ships between MSS data response and forest cover types.
The results of the investigations of MSS response and forest type
recognition shows the good identication effect on forest, field,
construction and bare land in band 4 and 5. But the bind 6 and 7 data
have the good information for natural features.
2 kinds of artificial conifer forests, 2 types of natural conifer
forest types and hard wood types are recognized by the influenced
light values changes by natural feature must be make more study.
2. The application of LANDAST data from regional forest conservation plan.
The landcover information by LANDSAT data was combined with census data,
topographic data or regional planning data for analysis the forest
functions on social lifes and evaluate each faculties such as timber
production, water shade potensialicy, elosion or flood control and
recreation purposes of habitants of regional area. Then the regional
forest conservation plan was prepared in north Kanto area of about
1500 km2.
Every forest faculties was qualified in each 2 x 2 km quadrate unit. The
land use zoneing work have been down very effectively by ADP opperation.
The working system shows in follow dagramme Table 2.
As the results of this work the LANDAST data show very efficient
utilization faculties for analyse the land cover condition with social life
of the regional habitants as the foundamental informations of basic
environmental conservation and developmei,t of the wide area.

Accomplishment
1. Color composit imageries of 6 sets LANDSAT-2 scenes was accomplished
and enlarged in 1/200,000 scale for to compare with the past imageries
of 1972. and 1973.
The differ area of the vegetation cover and feature between those
imageries was finds out mostly clear cutting in forest area and
glasscover increasing in swanpy area.
The LANDSAT-2 scenes show much better possibility to forest type
classification work than LANDSAT-1.
The test sit area we prepareing in Hokkaido for LANDSAT-2 CCT ADP
works.
2. Landcover maps and their application for forest conservation plan by
ADP, total 1500 km2 area of North Kanto was printed out from LANDSAT-1
CCT in 11 categories and 100 m2 mesh. This work are followed by CCT
LANDSAT-2 data perpareing.
3; The investigation for the ecological influence of road construction
and soil elosion in forest area was carried out by using the ADP
vegetation map of LANDSAT-1 CCT and LANDSAT-2 color composit imageries
in Central Japan area. Also air MSS and IR photo survey data was
combinated them. As the results of field checking about 85% of forest
types and 95% of elosion area was correctly maped and measured with
4 weeks opperation. This research works for forest monitering will
be followed as soon as LANDSAT-2 CCT offering.
