Malaysian Dams Portal




For separate link and better preview,
http://bit.ly/13xDEEY

Disclaimer: I, Danesh Prakash Chacko, as the producer of the map fully credit the various sources of data that identified both the locations and attributes of the dams. This included government sites, engineering companies, UTM copyrighted thesis, blogs and news sites. I hereby disclaim the ownership of the data found in the map portal.
Anyway the map portal should be used for study, research and personal use. No way it should be referred as a commercial source or tool for advanced analysis as the accuracy of the data could be questionable.

Introduction
From controversial 12 Dam project in Sarawak to water crisis in Selangor, water and dam issues has surfaced as hot political debates across the political spectrum. With the emergence of the idea of all development is good, dams plays both positive and negative role in sustainable development. The plan to make Sarawak into renewable energy hub have met stiff resistance among the indigenous communities as mass population displacement would occur. Meantime, in Selangor, political parties are squabbling on whether Selangor has enough water for its own needs or not and grand plan to bring water from nearby dam in Pahang (Kelau Dam) plus Langat 2 issue. Whilst the post would not highlight the issue thoroughly, I have decided the first step of awareness of water issues is to create information portal about dams.

The Malaysian Dams Portal highlights roughly around 90 dams in Malaysia, both constructed and proposed ones. The 'Portal' show where there are distributed, the purpose, the capacity, completion year and installed electricity capacity. Let me clarify on the accuracy of the spatial and attribute data of the dam. The dam locations were identified through Google Maps, FAO articles and other university or government publications. The dam locations were mapped out on a scale of 1:200 000 where the coordinates represent the location of the dam walls (if not, the centre of the reservoir at rare instances). Since the dam wall is big and some inaccuracies exist in coordinates, the map position of the dam could be off from 30 to 100 metres from any point of the dam wall. For the case of 12 proposed Sarawak dams and new Sabah dams, the accuracy of the location is very coarse. They were mapped out at the scale of 1:500 000 to 1:1 000 000. Pointing back to the disclaimer, it should be used as a guide, not a business or serious analytical tool.

You might observe where some sections on the 'notes' stating 'Request for Other Information'. This is because some of the dam attributes could not be identified at all. I am appealing to the readers and users of the blog and portal to contribute authoritative sources to fill the gaps. Having said that, please drop your queries on my blog to address the missing or questionable information.

As much as possible, usage of Wikipedia is limited to 10% of the data collected. The next section list out all the sources I have compiled for the dam location and attributes.

Limitations
Please drop in your queries on mistakes, what extra information should be added, better web map portals or others on the blog. This web map service is powered by online GIS Mango Map. I am considering to do this similar portal on ArcGIS Online to have more interactivity (though initial attempts have failed). If it works, I will post as a separate links.
