1. INTRODUCTION
LANDSAT MP CP vas made experimentally in another work.
It is a LANDSAT MSS CCT data which pixels are arranged as the scene
can be superimposed rigorously to the topographical map of the same
area.
It is considered that, if the LANDSAT MSS data is rearranged as
another type of MSS CCT array which describe the landscape containing
topographical features or vegetational color as it were viewed from
the level of ordinary human eyes on the ground, it is valuable for us
when making a scenery planning by evaluation of the actual landscape.
To realize this, considering a method for it and obtaining a
sample set of LANDSAT MSS CCT data and corresponding topographical
data, a LANDSAT landscape drawing is displayed on the CRT of Image-100.
2. OUTLINE OF LANDSAT LANDSCAPE DRAWING
Three dimentional coordinates is attached to each pixel of LANDSAT
MSS data, then an image will be transformed as a landscape as it were
viewed by human eye in actual. The transformation needs following two
procedures:
One is rearrangement of LANDSAT MSS data to be suitable for the
topographical map. Another is the method how to acquire the three
dimensional coordinates and attach it to each corresponding MSS pixels.
The former is described in detail previously on the other papers.(1),(2)
In this paper, the latter is focused. That is, both a procedure of
the correspondence between ground elevation data and LANDSAT MSS data
and a transformation technique of MSS data to perspective drawing are
described. The flowdiagram of making the LANDSAT LANDSCAPE is shown
as Figure 1.
3. LANDSAT MAP AT THE MT. FUJI AREA
As shown in Figure 2, Mt. Fuji area is chosen to make
the perspective drawing from LANDSAT MSS data. This area is one of the
most familiar place for Japanese and also Mt. Fuji is a symbol of Japan.
The test site is defined by two latitude lines from 35°18'51.9"N to
35?24'16.1"N and two longitude lines from 138?40'36.2"E to 138°47'14,2"
E. The arrow on Figure 2 shows a view point of perspective drawing.
LANDSAT MSS data used here was acquired on l4th December, 1972.
Photo. 1 is the LANDSAT MAP of the test site displayed on the Image-100.
The size of the image have 200 pixels x 200 lines. This size is same
as the size of 10 km x 10 km in the actual ground surface. One pixel
consists of a 50 m x 50 m area.
