“Istant HTML5 geolocation” un grande ‘how to’“Istant HTML5 geolocation” a great how to……

Ciao a tutti,

Ho appena finito di leggere un bel ‘how to’ sulla “geolocalizzazione” dal titol “HTML5 Geolocation Istant how to” scritto da Ben Werdmuller

Di seguito la mia recensione:

Questo manuale, pur essendo diretto agli sviluppatori, può essere molto utile anche ad altre categorie di professionisti, compresi quelli che hanno a che fare con il mondo del GIS e quindi con il concetto di georeferenziazione. Questo libro descrive quali potrebbero essere le interazioni tra utenti e applicazioni web; personalmente sono stato in grado di capire le significative e profonde implicazioni tra i temi trattati nel manuale e le applicazioni pratiche del GIS. Anche se non sono uno sviluppatore, il grande Ben Werdmuller ha saputo guidarmi attraverso i linguaggi Java-script e php a connetterli, in modo semplice ed intuitivo, ad oggetti più vicino a me come ad esempio un file KML o GPS .

Un altro aspetto particolarmente importante è l’approccio molto chiaro ed efficace relativo al tematica della sicurezza delle informazioni personali e la tutela della loro privacy.

Come è mia abitudine, al fine di verificare l’efficacia dei processi, ho eseguito passo passo tutte le procedure operativce testando tutto il codice nel manuale; anche in questo caso ho trovato molta chiarezza di esposizione e dei contenuti esposti dall’autore. In particolare, l’autore affronta a fondo e in modo esauriente tutti gli argomenti, con la conseguenza che il lettore trova una risposta a (quasi) tutte le possibile domande; questo conferma ancora una volta la professionalità dell’autore, che è già ben noto al pubblico settore. Infine, è da sottolineare l’eccellente modello utilizzato dalla casa editrice Packt (già adottato in molte delle sue altre pubblicazioni) per organizzare e presentare i temi trattati a vantaggio di immediatezza e chiarezza, che aiuta in maniera importante il lettore nella comprensione del contenuti esposti.

I’ve already read a great how to on “geolocation” named “Istant HTML5 geolocation how to” written by Ben Werdmuller

Below my review:

This manual, while being more directed to professional profiles web-developing oriented, can also be very helpful for other categories of professionals, including those who have to manage with the world of GIS and then of georeferencing. Reading this book you will understand which could be the interactions between users and web applications; personally, since I’m a GIS technologist, I have been able to achieve significant and deep implications among the topics treated in the manual and the practical applications of GIS. Even if he is not a developer, the great Ben Werdmuller has been able to guide me through the ​​java-script and php languages to connect them, in a simple and intuitive way, to objects closer to me such as a KML or GPS.

Another particularly important aspect carried out with a very clear and effective approach in the manual is that relating to the security of users information and the protection of their privacy.

As is my habit, in order to check the effectiveness of the procedures explained, I have played step by step all the procedures and have tested all the code in the manual; even in this case I found the clarity of exposition and the thickness of the contents exposed by the author. In particular, the author faces thoroughly and exhaustively all the topics, with the consequence that the reader finds an answer to all his questions on the matter, and this once again confirms the professionalism of the author, which is already well known to the public sector. Finally, the excellent model used by the publishing house Packt (already adopted in many of his other publications) to organize and present the topics covered must be underlined, to the advantage of immediacy and clarity that help in an important way the reader in understanding the content exposed .

GeoServer Beginner’s Guide (not only for novice)

Let’w talk about a new book on Geoserver: a useful manual for everyone.Here’s my review:

“Who has had the idea of entitling this book “Beginner’s guide”? This manual is much much more! Actually, besides supplying beginners with the basics of GIS and Geoserver, it can well work as an operational manual at a more specialized level. Since several years I’ve been working with this software (Geoserver) for job, and therefore I have matured a certain experience; in the book I found some information on Geoserver that previously I could obtain only through several researches in websites and thematic forum. I’ve appreciated very much the “practical” sections and the multi-choices quiz that invite the reader to think again to what he has previously read and, possibly, to read it once more.

The section on GIS basics is very important because the given notions help in understanding and fully exploiting the potential of Geoserver; I’ve enjoyed very much to successfully execute on an ubuntu-like system the detailed and precise procedure for installing Geoserver and all necessary software. Chapters 3, 4 and 5 gradually introduce the reader into the secrets of the management interface and to the way of accessing and loading spatial data. Also in this case I’ve tried to execute the described procedures by following the tips of the authors: surprise! I’ve found myself perfectly comfortable both as an “absolute beginner” and as a GIS expert. The descriptions and the observations on the “WMS reflector” functionality are very useful, since this tool helps the user to publish spatial data according to his own needs.

Also in chapter 6 the approach is very “soft”, since it introduces the reader to the basics of the largely applied OGC standard; but then, gradually, the book checks the reader’s abilities with the practical section “time for action”, sums up the notions he has just learned with “What just happened?” and finally brings him to dare with the section “Have a go hero”.

In my opinion, from chapter 7 on, topics switch to an intermediate level: implementation of simple webgis applications, configuration of geowebcache software to enhance performances, description of REST interface to automatize tasks, up to the very important topic of security are treated. Nevertheless, the confidential tone, the numerous references to examples and practical procedures, together with the concepts learned in the previous chapters, allow even the less expert reader to try to implement and manage a simple spatial data infrastructure.

Chapters 11 e 12 are really appreciable: they list and describe the basics (and not only) for tuning Geoserver and enhancing its performances in enterprise environments, and how to manage “troubleshooting” also by means of several active “mailing lists”. I’ve been impressed by finding in about 30 well organized pages all the useful references, which makes this book resemble a real, easy-to-use and complete “practical handbook” To sum up, I think that this book is suitable and complete both for those who approach Geoserver for the first time and for those who work daily with this software.”

That’s all!  Good job!
