enhancement and adjusting brightness and tone along
with saturation, pulled open color contrast, demanded

REMOTE SENSING DATA CHANGED
INFORMATION PICKING UP
Applying the way of combining auto-discovering
with artificial discovering picked up changed
information. Adopting the method of spectrum
feature variation and main composition analysis and
false-color synthesis, picked up changed information
in Weihai monitoring region, in order to prevent
omission of changed information effectively.
Applying the means of man-computer interaction
interpretation picked up change area in image of
changed information enhancement, change arca was
depicted by manual way. The definition of change
type was adopted to combining interactive visual
interpretation with computer processing. The
expression of changed information was as unit by
monitoring region, change map-speck was numbered
united according to the order of from left to right and
from up to down, serial number of map-speck was
sole in monitoring region. Confirmed change
map-speck was depicted boundary of map-speck by
red color, doubted change map-speck was depicted
boundary of map-speck by yellow color. The size of
selecting spectrum feature map-speck was site area of
659
Fusing way applied to IHS transformation. IHS
transformation made color RGB three kinds of
primary color separate themselves from, RGB three
kinds of primary color was cut apart into hue H, color
intensity | and degree of saturation S three weight.
The advantage of IHS coding was able to separate
intensity from color.
The main purpose of fusing image rear processing
was improving visual sense effect of image further,
strengthening special subject information, veins
information was the most important. Fusing image
would be processed through straight-square-map
adjustment, USM sharpening, color balance, color
intensity adjustment and degree of saturation
adjustment, contrast enhancement and so on.
300m*300m, its average value and variance was
tested according to type of feature map-speck , its
serial number was numbered according to the order of
from left to right and from up to down, by Weihai
monitoring region unit.
6 WILD INVESTIGATION AND CHECKING
The main task of wild investigation was collecting
program map of fundamental farmland protection
region and land modification investigation
information; looking into change map-speck one by
one, defining actual change situation; replenishing
monitoring omission map-speck, at the same time
surveying arca of fragmental land-object on the site;
modifying or replenishing concerned boundary;
verifying spectrum features map-speck.
GPS wild investigation applied three case double
frequency WILD200 GPS receiver to survey width
and length of linear land-object on the spot, especial
to new increasing roads and broadened roads; In
order to verity the precision and accuracy of inside
works interpretation, 15 percent of map-speck had
been selected to survey its area and position in
Weihai city jurisdiction over three town and one
district.
