Uczymy się wykorzystywać je do własnych celów. Coraz rzadziej zwracamy się do profesjonalistów z problemami, gdyż dzięki technologii jesteśmy w stanie poradzić sobie sami. Odkrywamy przy tym mnóstwo nowych, inspirujących aspektów życia. Dzięki tej książce można opanować podstawy bardzo przydatnej, choć do tej pory specjalistycznej dziedziny - kartografii i analizy danych przestrzennych. W dodatku bez dodatkowych kosztów - w darmowym, intuicyjnym programie Quantum GIS. Mapy potrzebne są wszystkim, nie tylko geografom! Jeśli pracujesz jako informatyk, logistyk, marketingowiec, dziennikarz, urzędnik czy architekt, prędzej czy później zechcesz przedstawić zgromadzone informacje w sposób wizualny, najlepiej na mapie. Dzięki tej książce bez większego trudu, a nawet z przyjemnością opanujesz zasady rysowania mapy, nanoszenia na nią obiektów według danych zawartych w tabeli, wyświetlania tych informacji, które są Ci potrzebne. Dowiesz się, jak planować trasę przewozu towarów, jak sprytnie policzyć budynki w każdej dzielnicy miasta czy jak najefektywniej rozsyłać ofertę handlową. Nauczysz się dowolnie zmieniać wygląd map, przekształcać je w obrazy i drukować lub umieszczać w Internecie. Nie jest to zwyczajny podręcznik. Wraz z tą książką będziesz krok po kroku zdobywać nowe umiejętności. Towarzyszyć Ci będzie młoda dziewczyna, Ula. Niejeden raz podsunie Ci użyteczną wskazówkę albo podpowie, co warto zapamiętać. Dzięki atrakcyjnej formie graficznej i ponad 300 ilustracjom zawsze zorientujesz się, gdzie w programie można znaleźć odpowiednie narzędzie. Analiza danych przestrzennych nie będzie miała dla Ciebie żadnych tajemnic. Do dzieła! Dzięki tej książce: ogarniesz wzrokiem przestrzeń i stworzysz mapę z Quantum GIS, poznasz serce współczesnej mapy w komputerze, zwiększysz użyteczność działania z pomocą narzędzi analitycznych QGIS. Odkryj dla siebie nową przestrzeń!
