• Format: ePub

Produktbeschreibung

With the help of the Internet and accompanying tools, creating and publishing online maps has become easier and rich with options. A city guide web site can use maps to show the location of restaurants, museums, and art venues. A business can post a map for reaching its offices. The state government can present a map showing average income by area.Developers who want to publish maps on the web often discover that commercial tools cost too much and hunting down the free tools scattered across Internet can use up too much of your time and resources. Web Mapping Illustrated shows you how to create maps, even interactive maps, with free tools, including MapServer, OpenEV, GDAL/OGR, and PostGIS. It also explains how to find, collect, understand, use, and share mapping data, both over the traditional Web and using OGC-standard services like WFS and WMS.Mapping is a growing field that goes beyond collecting and analyzing GIS data. Web Mapping Illustrated shows how to combine free geographic data, GPS, and data management tools into one resource for your mapping information needs so you don't have to lose your way while searching for it.Remember the fun you had exploring the world with maps? Experience the fun again with Web Mapping Illustrated. This book will take you on a direct route to creating valuable maps.

Autorenporträt

Tyler Mitchell is the author of Web Mapping Illustrated - a book focused on teaching how to use popular Open Source Geospatial Toolkits. He works as the Executive Director of the Open Source Geospatial Foundation, aka OSGeo. He has over a dozen years of industrial geospatial and GIS experience in natural resource management and forestry in western Canada. He came to open source to find tools that he could use throughout his career as a geospatial professional. What he found were tools that could dramatically improve enterprise, corporate-wide, geospatial data management and communication. He is an avid proponent of the popular web mapping program, MapServer, and other spatial data management tools including PostGIS, GDAL/OGR and QGIS. His work and interests include geospatial and tabular data management, analysis, manipulation and visualization through maps.

Rezensionen

"Mit einer klaren Struktur führt Mitchell anhand anschaulicher und nachvollziehbarer Beispiele den Leser von den Grundlagen der digitalen Kartographie hin zum Anbieten von Kartenmaterial über das Internet. Gegenstand des Buches sind Grundlagen digitaler Kartierung und GIS-Systeme, basierend auf Open Source-Software. Im Gegensatz zu den kommerziellen Mammutprogrammen von ESRI und MapInfo können Leser dadurch alles ohne weitere Umstände durchspielen. [...] Mitchell ist ausgewiesener GIS-Experte. Er vermittelt dem Leser umfangreiches Wissen in knapper und verständlicher Form. [...] In jedem Falle ein empfehlenswertes Buch." - Christian Wilk/iX 4/2006

"Kommerzielle Werkzeuge für die Graphische Informationsverarbeitung kosten meist viel Geld und die Suche nach freier Software, die über das Internet weit verstreut ist, kann zumindest viel Zeit in Anspruch nehmen. In seinem Buch mit dem Untertitel "Using Open Source GIS Toolkits" hat Tyler Mitchell alle wichtigen Werkzeuge zusammengetragen und zeigt wie man sie einzeln oder auch in Kombination anwendet, einschließlich MapServer, OpenEV, GDAL/OGR und PostGIS. Er erklärt ebenso, wie man Kartendaten über das Internet und unter Anwendung von OGC-Standard-Services wie WFS und WMS findet, sammelt, versteht, verwendet und teilt.Das Buch hilft in jedem Fall, wenn es um die Arbeit mit freien Werkzeugen in der Welt der graphischen Informationsverarbeitung geht." - Niels Gründel, Netzkritik.de, 10/2005
