News from the Royal Thai Survey Department:
Until recently the only publically available 1:50,000 maps of Thailand
was series L7107. This was only available for about a third of the
country. The series has lat/long but no UTM grid, was about 15-25 yrs
old and was of low quality: contours sketched in, roads not
differentiatd by sealed/unsealed, lack of detail, etc. However, for
where it was available, it was the best because it was all that was
available.
In January I reported that a cluster of Series L7018 sheets had been
made available for public sale through the Department's office in
central Bangkok. These appeared to cover areas affected by the 2004
Tsunami (Andaman cost), so I guessed that they were made available for
relief agencies and others. This series, in the publically available
edition, again has Lat/Long, but no UTM grid, but is 5-15yrs old
(possibly even more recent) and is drawn to US military standards, so
contours, roads, features are shown more accurately and in more detail.
Both series are bilingual.
It appears I was wrong in the reason for the appearance of the sheets.
It seems the Department is slowly releasing more sheets of this series.
On my visit last week about half of the Thai peninsula south of Bangkok
was now available, and staff hoped the entire series would be available
by the end of next year.
Available sheets include in the East:
5334-2&3
5234-1,2,3 (Rayong)
5235-2
5135-2 (Pattaya)
Near Bangkok:
5035-1
Upper peninsula:
4934-1 (Thayang)
4933-4
Lower peninsula:
4830-2,3 (Chumphon) and about half of all sheets south of here, mainly
the west coast (in fact all the est coas and islands except Ranong
4728-4 7
4628-2) but including a number of sheets on the east coast such as the
southern half of Ko Samui (4927-1,2,3,4) of particular interest is the
fact that 2 of the released sheets are on the Burmese border: series
L7017 was never available for areas anywhere near the border. however
militaryareas, such as south of Pattaya and the deep south of Thailand
are not yet available. hopefully Bangkok sheets will be released soon!
