peran GIS di pemilu USA

Pemilihan presiden di Amerika Serikat biasanya menjadi artikel penting yang diliput oleh media. Peristiwanya terjadi empat tahun sekali. Pada media USAToday, pemetaan data pemilu dilakukan dengan GIS (ArcView). Manfaat dari data ini selain untuk menceritakan perkembangan hasil pemilu bagi para pembaca, juga membantu wartawan dalam meliput beritanya. Warna merah untuk Bush, sedangkan warna biru untuk Al Gore.

catatan:
GIS merupakan singkatan dari geographic information system, atau sistem informasi geografis.

Led by database editor Paul Overberg, USA Today mapped out the electoral college results for its more than two million readers using MapShop (see “The Associated Press Develops MapShop”), bringing the latest computer mapping technology into the newsroom for election analysis and presentation.

In addition, USA Today used ArcView GIS for mapping, county by county, the election methods used for tallying votes. The use of GIS to map the historic 2000 election provided a new paradigm for using GIS in covering and reporting election results. And USA Today’s historic Bush/Gore county-by-county map illustration would be used on many of the network news programs as well as such wide-ranging media as MSNBC’s Imus in the Morning, Live with Regis, CNBC news, and The Rush Limbaugh Show Web site.

USA Today has been using GIS since 1990 and used ArcView GIS to map the 1996 presidential race. While already effective in creating data-rich, visually compelling maps, USA Today recently became a MapShop beta tester and utilized the joint ESRI/Associated Press online mapping system to more quickly and easily generate the 2000 election results.

If square feet could vote McCain would have won. But most of those red counties are mostly fields mountains and piles of horse manure. To be accurate you have to show each house as red or blue and green for all the fields and parks.

Terjemahan bebas :
Jika gambar kotak kecil dianggap sebagai representasi suara, maka McCain yang menang. Karena kotak kecil warna merah mendominasi peta. Namun perlu dipahami, bahwa daerah (counties) yang bertanda merah, kebanyakan berupa daerah pegunungan dan di sana lebih banyak kotoran kuda (horse manure) daripada keberadaan manusia. Agar lebih akurat, sebaiknya gambar GIS itu merepresentasikan rumah berwarna merah atau biru, serta warna hijau yang menggambarkan padang atau ladang (yang kosong atau jarang dihuni manusia).
