ArcCatalog使用手册

2008-11-20 20:00:40

ArcCatalog可用于浏览和管理数据。连接数据后，即可使用Catalog浏览其内容。当找到想要使用的数据后，可以将其添加到地图中。通常获取到项目所需数据后，不能立即使用它，可能需要改变它的投影或格式，修改属性，或者将其他表中存储的属性与地理要素进行链接。数据最终准备完毕后，需要把数据内容和所作修改存档。这些数据管理的工作可以采用Catalog中提供的工具来完成。

FME中文教程（2008 版）

2008-11-10 00:17:00

FME的英文全拼是Feature Manipulate Engine，是加拿大safe Software公司的产品，简单说FEM就是GIS数据转换平台，它能够实现100多种数据格式(模型)的相互转换.如果从技术层面上说，FME 不再将数据转换问题看作是从一种格式到另一种格式的变换，而是完全致力于将GIS 要素同构化并向用户提供组件以使用户能够将数据处理为所需的表达方式。事实上，许多GIS用户为了在同一系统中获得不同的数据表达方式，也使用FME来操纵数据。

FME产品包含以下六个功能模块：

(1)
FME Workbench
当用户定制自己的数据转换时，利用FME Workbench模块，只需要在直观的界面中“指指点点”就可以轻易完成非常复杂的数据转换任务，而且数据转换质量非常理想；能够可视化地定义从原数据到目标数据的对应关系（属性和图形）；同时还可以使用该模块进行不同格式数据源的合并工作。

(2)
FME Universal Translator
该模块是FME的旗舰产品，是一个独立运行的强大的数据转换程序，采用drag-and-drop界面，用户可以轻松地、精确地转换、存储100多种不同格式的数据，用户也可以完成比较复杂的数据处理过程，比如给数据加属性值等。

(3)
FME Universal Viewer
该模块用于快速预览不同格式的数据。用户可以在使用Workbench或Translator.模块时，在做数据转换之前预览转换数据（属性和图形）

(4)
FME Plug-in(SDK)
该模块为开发组件，使用该软件开发工具包，开发人员能访问FME强大的语义核心，加入自己定制的数据格式，或者轻松进入FME转换内核去处理（只不过要额外追加费用）。一旦定制的数据格式加入FME内核就能够被所有的FME用户使用。

(5)
FME Object API
这个开发接口能把FME的数据访问能力定制置入应用模块，用于增加数据的读、写、处理能力。开发语言支持Java, C++, C, COM (VB, C#), Delphi 和ArcView Avenue。

(6)
FME Application Extenders
该模块给用户提供了一个直接访问（读、写）多平台GIS、CAD和数据库格式的应用。

Product Description
A Practical, Up-To-Date Guide To Modern Methods In The Analysis Of Time To Event Data.

The rapid proliferation of powerful and affordable statistical software packages over the past decade has inspired the development of an array of valuable new methods for analyzing survival time data. Yet there continues to be a paucity of statistical modeling guides geared to the concerns of health-related researchers who study time to event data. This book helps bridge this important gap in the literature.

Applied Survival Analysis is a comprehensive introduction to regression modeling for time to event data used in epidemiological, biostatistical, and other health-related research. Unlike other texts on the subject, it focuses almost exclusively on practical applications rather than mathematical theory and offers clear, accessible presentations of modern modeling techniques supplemented with real-world examples and case studies. While the authors emphasize the proportional hazards model, descriptive methods and parametric models are also considered in some detail. Key topics covered in depth include:
* Variable selection.
* Identification of the scale of continuous covariates.
* The role of interactions in the model.
* Interpretation of a fitted model.
* Assessment of fit and model assumptions.
* Regression diagnostics.
* Recurrent event models, frailty models, and additive models.
* Commercially available statistical software and getting the most out of it.

Applied Survival Analysis is an ideal introduction for graduate students in biostatistics and epidemiology, as well as researchers in health-related fields.

Modeling our World（英文版）

2008-10-14 09:22:07

美国Esri公司官方出品的地理信息系统基本原理、方法。通读之后可以掌握地理信息系统的大部分概念，用计算机来表示我们生活着的地球，对使用ArcGIS等GIS软件有着指导性作用。

This book serves a variety of different purposes. For
the geographer or scientist, it defines a conceptual
context for representing geographic information. For
the GIS specialist, it serves as a guidebook in
designing and using geographic databases. Finally, it
introduces database concepts to a geographic
audience, and geographic concepts to the database
specialist.
ArcInfo 8 defines a unified framework for
representing geographic information in a database.
Several different generic data models are supported
within this framework:
? cell-based or raster representation
? object-based or feature-based representation
? network or graph-element representation
? finite-element or TIN representation
Each of these generic models has its own vocabulary
used to define and reason about geographic
information. When we decide to represent roads,
rivers, terrain, or any sort of phenomena in a GIS,
we need to decide exactly how we define
information in terms of these generic models. As
chapter 1 points out, there are many ways that
information can be modeled in a GIS. The
representation you choose for the data model will
affect how you sample and measure geographic
information, how you display it visually, and which
relationships between elements can be represented,
as well as query and analysis operations that can be
applied to the information.

Data Munging with Perl

2008-09-22 15:27:07

The book begins by addressing introductory and general topics, before gradually
exploring more complex types of data munging.
PART I sets the scene for the rest of the book.
Chapter 1 introduces data munging and Perl. I discuss why Perl is particularly
well suited to data munging and survey the types of data that you might meet,
along with the mechanisms for receiving and sending data.
Chapter 2 contains general methods that can be used to make data munging
programs more efficient. A particularly important part of this chapter is the discussion
of the UNIX filter model for program input and output.
Chapter 3 discusses a number of Perl idioms that will be useful across a number
of different data munging tasks, including sorting data and accessing databases.
Chapter 4 introduces Perl’s pattern-matching facilities, a fundamental part of
many data munging programs.
PART II begins our survey of data formats by looking at unstructured and
record-structured data.
Chapter 5 surveys unstructured data. We concentrate on processing free text and
producing statistics from a text file. We also go over a couple of techniques for converting
numbers between formats.
Chapter 6 considers record-oriented data. We look at reading and writing data
one record at a time and consider the best ways to split records into individual
fields. In this chapter, we also take a closer glance at one common record-oriented
file format: comma-separated values (CSV) files, view more complex record types,
and examine Perl’s data handling facilities.
Chapter 7 discusses fixed-width and binary data. We compare several techniques
for splitting apart fixed-width records and for writing results into a fixed-width format.
Then, using the example of a couple of popular binary file formats, we examine
binary data.
PART III moves beyond the limits of the simple data formats into the realms of
hierarchical data structures and parsers.
Chapter 8 investigates the limitations of the data formats that we have seen previously
and suggests good reasons for wanting more complex formats. We then see
how the methods we have used so far start to break down on more complex data
like HTML. We also take a brief look at an introduction to parsing theory.
Chapter 9 explores how to extract useful information from documents marked
up with HTML. We cover a number of HTML parsing tools available for Perl and
discuss their suitability to particular tasks.
Chapter 10 discusses XML. First, we consider the limitations of HTML and the
advantages of XML. Then, we look at XML parsers available for use with Perl.
Chapter 11 demonstrates how to write parsers for your own data structures
using a parser-building tool available for Perl.
PART IV concludes our tour with a brief review as well as suggestions for further
study.
Appendix A is a guide to many of the Perl modules covered in the book.
Appendix B provides a rudimentary introduction to Perl.

Web Data Mining: Exploring Hyperlinks, Contents, and Usage Data

2008-09-18 07:46:23

Product Description

Web mining aims to discover useful information and knowledge from the Web hyperlink structure, page contents, and usage data. Although Web mining uses many conventional data mining techniques, it is not purely an application of traditional data mining due to the semistructured and unstructured nature of the Web data and its heterogeneity. It has also developed many of its own algorithms and techniques.

Liu has written a comprehensive text on Web data mining. Key topics of structure mining, content mining, and usage mining are covered both in breadth and in depth. His book brings together all the essential concepts and algorithms from related areas such as data mining, machine learning, and text processing to form an authoritative and coherent text.

The book offers a rich blend of theory and practice, addressing seminal research ideas, as well as examining the technology from a practical point of view. It is suitable for students, researchers and practitioners interested in Web mining both as a learning text and a reference book. Lecturers can readily use it for classes on data mining, Web mining, and Web search. Additional teaching materials such as lecture slides, datasets, and implemented algorithms are available online.

About the Author

Bing Liu is an associate professor in Computer Science at the University of Illinois at Chicago (UIC). He received his PhD degree in Artificial Intelligence from the University of Edinburgh. Before joining UIC in 2002, he was with the National University of Singapore. His research interests include data mining, Web mining, text mining, and machine learning. He has published extensively in these areas in leading conferences and journals. He served (or serves) as a vice chair, deputy vice chair or program committee member of many conferences, including WWW, KDD, ICML, VLDB, ICDE, AAAI, SDM, CIKM and ICDM.

Graph Theroy

2008-09-14 04:36:59

Graph theory is a flourishing discipline containing a body of beautiful and powerful theorems of wide applicability. Its explosive growth in recent years is mainly due to its role as an essential structure underpinning modern applied mathematics – computer science, combinatorial optimization, and operations research in particular – but also to its increasing application in the more applied sciences. The versatility of graphs makes them indispensable tools in the design and analysis of communication networks, for instance.

The primary aim of this book is to present a coherent introduction to the subject, suitable as a textbook for advanced undergraduate and beginning graduate students in mathematics and computer science. It provides a systematic treatment of the theory of graphs without sacrificing its intuitive and aesthetic appeal. Commonly used proof techniques are described and illustrated, and a wealth of exercises - of varying levels of difficulty - are provided to help the reader master the techniques and reinforce their grasp of the material.

A second objective is to serve as an introduction to research in graph theory. To this end, sections on more advanced topics are included, and a number of interesting and challenging open problems are highlighted and discussed in some detail. Despite this more advanced material, the book has been organized in such a way that an introductory course on graph theory can be based on the first few sections of selected chapters.

Introduction
Living (in the) post
With the public sector, education, the welfare state – all the big, ‘safe’ institutions – up against
the wall, there’s nothing good or clever or heroic about going under. When all is said and
done, why bother to think ‘deeply’ when you’re not being paid to think deeply?1
Dick Hebdige
Face it: You’re always just a breath away from a job in telemarketing.
2
Douglas Coupland
University teaching is a special job. It is a joy to wake up in the morning knowing that
during each working day, an extraordinary event or experience will jut out from the
banal rhythms of administration, answering emails and endlessly buzzing telephones.
Students, in these ruthless times, desperately want to feel something – anything – beyond
the repetitive and pointless patterns of the casualized workplace and the selection of
mobile phone ring tones. This cutting consumerism subtly corrodes the self. These
students follow anyone who makes them feel more than a number, more than labour
fodder for fast food outlets. I believe in these students, and I need to believe that the
future they create will be better than the intellectual shambles we have bequeathed them.
Being a teacher is a privilege to never take for granted. The bond between students and
educators is not severed when a certi?cate is presented. We share a memory of change,
of difference, of feeling that we can change the world, one person at a time.
In 2002, I wrote about teaching in a rage. Digital Hemlock3
was an angry book, howling
at the economic decisions and choices made by our university administrators, prioritizing
technology over people, and applications over ideas. I was frustrated and amazed at the
gnorance and ineptitude that was dismissing the expertise of teachers, and ignoring the
outstanding range of educational literature urging caution in unstintingly embracing
technological change over more nuanced theories of learning. The response to this
embittered book from readers was immediate, powerful and embracing. Letters ?ooded
my mail box. Emails deluged my in-box. It was as if neglected and concerned teachers
had been seething with anger – waiting to express critique and ask the dif?cult questions
