Document Summary
Such as sars (in china) and zita (in brazil) Determine query/analysis criteria (i. e. how to merge the different layers of soil, geology, elevation together) Then re-classify all those areas to the same format. Geospatial data visualization pipeline (as proposed by ben fry) Parse --> provide some structure and order for the data. Filter --> remove all but the data of interest. Apply methods to discern patterns or context (arcgis analysis tools) Refine --> improve the basic representation to make it clearer and more visually engaging. Interact --> manipulate the data or control what features are visible. -> are you concerned about snow and melting depending on the aspect (e. g. north/east) -> determine first what is the farthest you want people to walk. Area, length relationships --> calculate the area in square meters (this is the default) Query (select by attribute) --> most useful of all analysis tools.
