The Czech National Node is concentrated on general information on protected areas on whole territory of the Czech Republic. It contains 2 shapefiles with so called "large sized protected areas" - National Parks and Protected Landscape Areas (PLA) and another shapefile with "small sized protected areas" - National Natural Reserves, Natural Reserves, National Natural Relics, Natural Relics. For detailed description of these types of protected areas see Newsletter no. 5. Last shapefile contains administrative borders in Czechia. The shapefiles use Czech national datum SJTSK with Krovak projection (universe conform conic projection with x - axis fixed as 42,5° Eastern from Ferro). Part of each shapefile is a database with basic information - area, perimeter, date of update and name and type of the protected area. In future we suppose to add short description of each "small" protected area, eventually links to webs of individual National Parks or Protected Landscape Areas (if these websites exist). Types of the protected areas are also differentiated in graphics by colours. National parks are in darker green (RGB=0,128,0), Protected Landscape areas in light green (0,192,0). "Small" protected areas are drawn by different colours on the contour and inside the shape. Natural Relics and Natural Reserves have yellow (255,255,0) contour, if these are "national" then the contour is green (0,128,0). Inside of the shapes are for Natural Reserves is used dark yellow-green (192,192,0) and for Natural Relics bright green (192,255,0). Administrative boundaries are violet (255,0,255). Initial extension is set to display large sized protected areas and administrative regions on the whole of Czechia. Small sized protected areas may be attached additionally. Navigation bar uses basic GIS tools: zoom in, zoom out, pan, information, movements to 8 directions and set scale and coordinates. Next to navigation bar is small interactive map of administrative regions of the Czech Republic - by clicking on a region this will be zoomed in whole extentin the main map.
