MRT through the Nature Reserve: "the line goes 'through' primary forest and good secondary forest."
Category : news
Two weeks ago, LTA announced that they would build “two new rail lines and three new extensions by 2030″. Of the proposed new lines, the 50km Cross Island Line (CRL) was the cause of considerable concern, as it would cut through the Central Catchment Nature Reserve and I posted a couple of maps for scrutiny [see maps in link].
I sent local naturalist and GIS-geek Tony O'Dempsey the Land Transport Authority's map for a second opinion about the placement of the line. I was interested to see the type of forest we knew to be present which the line would cut through.
Tony replied shortly after, saying, "I georeferenced that LTA map and co-registered it with this satellite image. The line goes 'through' primary forest and good secondary forest."
Tunnelling or overhead, construction is not a neat business. And if it will occur in our nature reserves, the integrity of an already impacted forest will be further challenged.

How to derive Google Maps links from NParks' new website
Category : internet
The recent NParks webpage makeover has happily introduced a Google Map thumbnail to each parks' listing. However, there is no link to Google Maps itself.
The significance of Google Maps?
A four step solution to the rescue
And just like that, the static thumbnails have all of the potential of Google Maps.
2. Find (cmd- or ctrl-F) the word "map " and 3. copy the coordinates.
Google Maps displays the location! Go forth and multiply!

Mok Ly Yng marks World Space Week 2007: Space at 50
Category : photos
"Map Man" Mok Ly Yng who presented us with "Singapore from Space - 40 years" in August 2005, now marks "World Space Week 2007: Space at 50 with an article and collection of satellite images - follow this link.
I just wished I had witnessed his race to Greenwich observatory grounds where a German couple saw him gasp "satellite, prime meridian, zero line"!
Thanks once again, Ly Yng!

Looking for turtle transmitters
Category : envt
On 1st August 2006, sea turtles with transmitters were released in the South China Sea. See "Sea Turtles to be released in the South China Sea for satellite-tracking." Habitatnews, 01 Aug 2006 - see news paper reports here.
The IOSEA newsletter has just reported that:
"An immediate cash reward of up to USD 500 is being offered for information on and return of two transmitters, which have been sending signals from land near the town of Krui, Indonesia."
See the IOSEA webpage.

Sea Turtles to be released in the South China Sea for satellite-tracking
Category : marine
See the Channel NewsAsia article.
In commemoration of the Indian Ocean - South East Asia (IOSEA) "Year of the Turtle", Underwater World Singapore (UWS) has collaborated with the National Institute of Education (NIE)/Nanyang Technological University (NTU) to launch a Sea Turtle Conservation Gallery and released 12 sea turtles fitted with satellite-tracking devices.
Dr C H Diong, a professor with National Institute of Education/NTU, will be releasing the 12 turtles fitted with tags into international waters in the South China Sea in an effort to study aspects of their biology and migratory behaviour.
If the turtles look a mite restricted, not to worry. They are in a cargo ship right now, heading out to the South China Sea. By the late morning of Tuesday, 1st Aug 2006, they will be released and be free-swimming once again.
Where will they go hence? Diong and others will be monitoring the sea turtles and hopes to share approximations of their positions on the internet.
The turtles were of three species - the Loggerhead Caretta caretta, Olive Ridley Lepidochelys olivacea and Green Chelonia mydas. Two loggerhead turtles were brought to Underwater World Singapore as hatchlings from Nagoya, Japan. After nine years of captivity, will they eventually head back to Japan? More details soon.
Meanwhile, Prof Leo Tan's welcome address included a whimsical comment on the persistent arrivals of mature female turtles to lay eggs in Singapore, after the 20-40 years it has taken them to mature. Singapore has a lot to offer even to migrating sea turtles, let alone our youth!

"Singapore from Space - 40 years"
Category : photos
For the past 8 years, MOK Ly Yng has been collecting images of Singapore taken from space that were available both on and off the web.
In July 2004 Ly Yng began asembling a collage of these images for our 40th National Day. Two of the 16 photos were taken by astronauts and span the period 1963 - 2005 to include the first satellite photos taken of Singapore.
Yesterday, 9th August 2005, he presented his effort via an email to the Singapore Heritage mailing list. The photo and his accompanying comments are archived here: "Singapore from Space - 40 years".
The collage was prepared to provide "a feel of the passage of time from 1965 to 2005', and we are urged to see if we can "pick out the visible changes both in Singapore and her immediate surroundings over these 40 years."

Satellite image of Singapore City, 9th August 2000
Category : internet
It's old news, perhaps, but Singapore City was featured in Space Imaging.com's Top 10 images - 2001 gallery. The image is a 'one-meter resolution color image of the city of Singapore collected on August 9, 2000 by Space Imaging's IKONOS satellite.'
"The image depicts the trade and administration centers located between the mouth of the Singapore River and Canning Hill. Included in the image are the Singapore International Convention and Exhibition Center, the War Memorial Park, and the famous Raffles Hotel. Between the St. Andrew's Cathedral and the river lay the historical buildings of Singapore including City Hall, the Supreme Court, and the Parliament House. ...

In the 300dpi, 2500 x 2200 pixel photo they provide, you can see old and new buildings side by side, the Esplanade under construction and the Starhub blimp. There are other images you can look out for, like this one from 2nd May 2003.

Satellite Maps of Singapore
Category : internet
In 2001, NUS' Centre for Remote Imaging, Sensing and Processing (CRISP) released a wonderful desktop wallpaper to The Straits Times (ST) - a satellite image of Singapore on a particularly cloudless day. The original ST webpage no longer holds the image. Happily, Habitatnews 2001-12 (7th June 2001) featured comments by Tang Beng Yong and was subsequently archived on the Habitatnews webpage as well. It has been there all along, but not all know to google it. So I'm making it easy and have added a map icon on the sidebar of Habitatnews (lower left) below the moon phase image. Click to get to the right page.
The satellite image was released for general use and is a useful teaching tool. Use it by all means, but do acknowledge the source - NUS' CRISP.
CRISP uses seven satellites to 'detect sea pollution, forest fires and other environmental problems'. See "Satellite images for the big picture." By Chang Ai-Lien, The Straits Times 23 Apr 2001 (thanks to Ecology Asia).
Another satellite map of Singapore on the net is Mapmart.com's vector base map of Singapore, with options for satellite and DEM maps which you can zoom in and out of.
There are probably more options out there, and please drop me a line if you some across something interesting or useful.
