The input photo coordinates of all control points (ground control points
identified on aerial photographs and photo control points) will be measured by the
ZEISS-Oberkochen monocomparator PK-1. The WILD PUG 4 Point Transfer Device
was selected for stereo-transfer of control points between overlapping aerial
photographs and for permanent marking of their locations in the film emulsion.
The orthophotographs will be printed at 1 : 50,000 scale (1 : 25,000 in Java,
Madura and Bali), that is, at approx. twice the scale of aerial photography and
mosaicked to 15 minutes x 15 minutes map sheets. These will be overprinted with
enhanced planimetric data (cultural features and hydrography), annotation
(geographic names, spot heights and cartographic symbols), map frame with
indicated U.T.M. coordinate grid, geographic coordinate grid, legend and with the
optional contours.
2.2. Compilation of Resource Data
Resource overlays will be compiled at the mapping scale of 1 : 50,000 at
specialized resource agencies. The main input for interpretation of resource data will
be color-IR (false color) aerial photographs at 1 : 80,000 scale which will be
recorded simultaneously with panchromatic photographs at 1 : 100,000 scale (see
3.2). In densely populated Java, Madura and Bali, the mapping scale will be 1 :
25,000, the scale of color-IR aerial photographs 1 : 30,000 and panchromatic
photographs 1 : 60,000. The color-IR coverage will not be continuous. Although it
will have 66% overlap assuring stereo-observation, there will be 20% sidegaps
between the flight lines. Interpretation of resource data in these gaps will be done
from panchromatic photographs at 1 : 100,000 (1 : 50,000) scale. This was a
compromise solution, to obtain the color-IR photography at 1 : 60,000 (1 : 30,000)
scale simultaneously with the panchromatic coverage at 1 : 100,000 (1 : 50,000)
scale, without changing the flight plan and without gross increase of the air-photo
budget.
Resource data interpreted from aerial photographs will be complemented by
data from supplementary and existing surveys and inventorles, to provide the most
complete record, at 1 : 50,000 (1 : 25,000) mapping scale, on forests, agriculture,
soils, geology and land use/land capability. Results will be plotted on
orthophotographs at the mapping scale, completed with annotation and sent to the
Central Resource Mapping Laboratories of BAKOSURTANAL for cartographic
compilation and printing of resource maps and for entering these data into the
National Environmental Geographic Information System.
