Introducing Geographic Information Systems with ArcGIS Third Version by Michael Kennedy
It seems to be arduous, for me anyway, to put in writing the preface for a 3rd version. As I attempted to compose this I put plenty of electrons within the recycle bin. Most of what I’ve to say was mentioned within the prefaces to earlier editions. And who desires to need to wade via eleven pages of these along with this one! So what I’ll do is simply to inform you concerning the new materials within the textual content after which simply summary and reference earlier info and concepts.
I’m eliminating the Preface to the Second Version. In case you haven’t used the e book earlier than, you most likely ought to learn the Preface to the First version, included after this one. First, in fact, is that the fabric is oriented to ArcGIS Desktop variations 10.0 and 10.1. The place there are variations between these two, and there are a number of, I’ve normally pointed them out. Nevertheless, these utilizing 10.0 will often should adapt the Step-by-Step directions, which favor model 10.1. I like to recommend utilizing 10.1 whether it is out there and you might be acquainted with it.
(To point the extent of the modifications, we will begin with the truth that the performance stage names have modified from these in model 10.0 and earlier than. In 10.1 ArcView is Primary, ArcEditor is Commonplace, and ArcInfo is Superior.) The CD-ROM utilized in earlier editions has been changed by a DVD, as a result of the information units are extra intensive and all of the figures within the e book can be found.
For the reason that first version, sections and workout routines have been added on the subjects of:
❏ Publishing maps on the Web, utilizing ArcGIS.com.
❏ Utilizing the Esri on-line knowledge service so as to add basemaps to the scholar’s map.
❏ The terrain knowledge construction, made potential by the emergence of LIDAR as a outstanding methodology of very dense knowledge assortment, is roofed each in concept and by train.
❏ Layer packages – a welcome invention which facilitates the switch of characteristic lessons of all codecs from one pc to a different, with out worries like relative path names and separate knowledge transfers.
❏ Since this e book is primarily geared toward getting ready professionals for utilizing GIS to do evaluation and synthesis (subjects separate from show and mapmaking, which, for completeness, is roofed in appreciable element in Chapter 3), topology performs an vital position. Quite a few workout routines, subsequently, emphasize using the topology capabilities of geodatabases, which is significantly completely different from these of coverages and utterly absent from the shapefile format.
