roam if you want to, roam around the world...

Hey.. reminds me of a B-52s classic... yes its a classic now... getting old... hahahahaa

roam if you want to
roam around the world
roam if you want to
without anything but the love we feel

fly the great big sky see the great big sea
kick through continents bustin bounaries
take it hip to hip rock it through the wilderness
around the world the trip begins with a kiss

Oklah… so far I have blogged a bit about programming, software, map theories, GPS, GIS data, satellite images… hhmmmm… we really now cannot avoid mentioning methods of acquiring spatial or geographic data. Spatial data here actually means maps…. or in more technical terms.. Vector (XY or Lat/Long in Points, Lines or Polygons) or Raster (Imagery). This field of study is also called geomatics.

What is this Geomatics?? Its like …. methods, skill and steps to get or record spatial data… basically XY or Lat/Long coordinates lah. All the collected points must be geographically referenced… what this means is all these numbers must actually mean something on the earth’s surface.

Its actually a mixture of science and art… instruments and algorithms(formulaes) to obtain location information is a scientific field of study… the geographer or mapping cartographer is the true artist. Masters (sifuuuu) like Da Vinci also drew maps among others. Trust me… there are so many equipments and instruments to find anything on, above or under the earth’s surface…
