Trip report regarding remote sensing activities at ... - Up To - SOPAC

RESULTS
Three maps were produced at the scale of 1/50000, : -
the Ba River Thematic Map (Viti Levu, FIJI), using the
SPOT image (April 1988);
_- the Ba River Thematic Map, using LANDSAT MSS data
(November 1978); the same processing as SPOT data
processing was applied to allow for a comparison of the
maps to monitor the changes within 10 years time;
-_ the comparison map between SPOT data and LANDSAT data in
the submerged part of the Ba River Delta.
Four zones are identified :
- the reef zone,
- the submerged river delta zone,
- the mangrove zone,
- the land area.
Various types of facies have been identified in each zones,
using only satellite information.
In the lagoon:
- a partition reef facies,
- two types of shallow marine reef,
- pinnacles,
- emerged surficial coral sands,
- submerged deltaic deposits.
In the wetland zone:
- tidal flat bare soils,
- a bushy type of mangrove,
- a shrubby type of mangrove.
Inland:
- the forest areas,
- a "bush" facies
- the inland bare soils,
- the sugar cane fields.
