Getting the hang of ArcGis
August 3, 2011 § Leave a comment
Here’s some images that were generated in class with ArcGis.
(Messing around with different projections. This one caught my eye, (the Gaus Krugner projection), as it focused on a certain longitude (and consequently subsequent narrow strips of areas) ).
(Playing around with manipulating symbology. The circles (and color) represent population size at cities.)
(When inverted, the population-map could almost be compared to night-time satellite photographs of cities and their densities of light pollution.)
(A screenshot from the process of extracting lat-long (y-x) data from a spreadsheet into an ArcGis file. Quite messy with the amount of data points (side-note: google earth compensates for this visual clutter by showing text according to zoom level) And Wow! Europe has a lot of World Heritage sites!)
Also, a nice quote that stood out from the lesson was that “All maps are lies.” (See Mark Monmonier’s “How to Lie with Maps”), and that maps are constructed for certain purposes, as such, certain representations of abstract and physical information can differ as a result of their intended message.
