Taking advantage of a week of business trip, the "Principles and Technologies" "The Principles and Technologies of Network Geographic Information System" written by Meng teacher were very inspired.
1. The official issuance of this is more than the spell of learning at school.
a Added Chapter 8 "Network GIS Engineering Technology and Engineering Management", change the original Appendix to Chapter 9: Commonly introduced by GIS software. For example: GIS project demand is not clear, non-technical management, etc.
b has added content on some chapters. Due to the long time, I don't remember the specific chapter structure. If there is any brothers and sisters, I can add this content, thank you! 2.6 Wireless network technology is new to add!
C adds the exercise. There is no exercise in the book. Now the increased exercise is closely combined with the foreword knowledge of this part. It is very beneficial to do it. Recommend the students of this book to do more. For a simple example, space The data engine is a middleware between () to provide a transparent and convenient spatial data service for the application system. Space data engine is a very strange noun for some people, but in practice, it is often considering using SDE between applications and DBMS when designing the system architecture. Have your own SDE.
D This book is the most recommended place to write the latest technical practices. Many chapters often make the designers in the dilemma Mouton. For example: 3.3.5 Section 2 High-resolution Remote Sensing Image Organization Management Chapter "In this sense, adoption of relational database and file combination method is a valid method in massive video data management. The basic idea is: Each remote sensing image is subjected to the necessary grades, block pretreatment, establishing a grading, blocking the indexing mechanism, stores and manages index information in the form of a database, and the original image and grading are saved by disk file. " For this paragraph, I want to use the large object-relational database to manage image data is the best way, but in some projects, the management of the database will bring massive system optimization and program development, and now It hasn't seen very effective scenarios to manage massive remote sensing data and achieve a good update. (I don't know if it is too arbitrary?
)
2, new concepts, new technology applications and instances explain detailed, very inspired and guided. Such as network GIS multi-server data technology, network storage classification, WebGIS design and development, WebGIS technology framework, based on .NET webgis structure, mobile GIS.
3 I myself a little idea: If you want to practice classmates, you can first look at the ninth chapter. After selecting a basic software, look at the previous content. The version of the software introduction is a widely used version in the market. Like: Arcims 9.0
GeoMedia Web Map also has open source webgis. This can be good, crazy on the Internet is called the open source era, these two stuff is worth seeing!
