Theory and method of data-spatial data mining technology Gejoco (Information Institute of Southwest Agricultural University 400716) This paper briefly discusses the theory and characteristics of spatial database technology and spatial data mining technology, this paper analyzes the level and method of spatial data

Oracle's Space database: 2007-12-21 16:31:12 Category: Oracle For a simple study, Collection See below for more information [@more @]1. What is Oracle's spatial database: Oracle's spatial database provides a set of SQL schemas and functions on how to store, get, modify, and query spatial datasets.Spatial data consists of the following:1.MDSYS Schema: storage, syn

Reproduced from: http://publishblog.blogchina.com/blog/tb.b?diaryID=5349656 Absrtact: Using Oracle spatial to store and manage spatial data, it is easy to solve the problems of data sharing, distributed processing, network communication, open development, concurrency control, networked integration, cross-platform operation and data security recovery mechanism, and thus becomes an application trend. How to

Oracle spatial is used to store, manage, and query spatial data. Provides a set of SQL scenarios and functions for storing, retrieving, updating, and queryingA collection of spatial elements in a database. Mainly by the geometric data type, spatial indexing mechanism, a set of operational functions, management tools. c

Spatial Data Mining refers to the process of extracting hidden knowledge and spatial relationships from spatial databases and discovering useful Theories, Methods, and technologies of features and patterns. The process of spatial data mining and knowledge discovery can be roughly divided into the following steps:Data p

I had nothing to worry about this afternoon. I accidentally reviewed the mysql manual. I used to check the content of the manual very well, the focus is on some basic details of SQL statements, mysql performance parameters, and storage control management. However, today I accidentally discovered an important feature of mysql, that is, mysql also stores spatial data related to gis. I had nothing to worry about this afternoon. I accidentally reviewed th

You are welcome to exchange ideas and improve your technology together. 1. Geographic Information System (GIS) GIS can be understood from three different perspectives. The first GIS is a spatial database, which contains a data model for expressing general GIS data (elements, grids, topologies, networks

Label:Some of my colleagues have asked me the following questions: We use the Oracle spatial sdo_geometry, isn't it useless arcsde? Whether we are using Oracle spatial or ARCSDE is a bit of a rip! Did the Create enterprise Geodatabase represent the use of ARCSDE? What is this action about? We don't use ARCSDE services, why do you say we use ARCSDE? ...... Because ask a lot of

We have encountered many performance problems. We generally recommend that you reread the spatial index. If you have dozens or even hundreds of spatial indexes in a database, what should you do? ArcGIS10.1 version RebuildIndexes: (this function is available only for ArcGIS10.1) this function is mainly used to edit a wide range of data for users, We have encountered many performance problems. We generally re

I. Spatial Index The existing index types of the database cannot be applied to the indexes of geometric objects in spatial data. The uncertain data structure and data operation methods make the existing indexes unsuitable, therefore, both Oracle Spatial and ArcSDE use domain indexes (domain index [1]In short, it is to create a new index type that is not in the d

I have previously written a research plan on the mechanism of Population Spatial Distribution in China and its simulation. The question is very big, and I don't think deeply. It is a rough idea. China is experiencing the largest population movement and migration in human history. According to the latest data from the sixth census, China's current urbanization rate is approaching 50%, in the future, China will enter a period of rapid urbanization, and

Spatial data mining refers to the theory, methods and techniques of extracting the hidden knowledge and spatial relations which are not clearly displayed from the spatial database and discovering the useful characteristics and patterns. The process of spatial data mining and knowledge discovery can be divided into seve

I used to check the content of the manual very well, the focus is on some basic details of SQL statements, MySQL performance parameters, and storage control management. However, today I accidentally discovered an important feature of MySQL, that is, MySQL also has the storage function for spatial data related to GIS, which suddenly aroused my interest, so I also foc

As a spatial database solution, ARCSDE is widely used, and this article will attempt to describe how SDE works and briefly describe how SDE users are used in a spatial database.How ARCSDE WorksARCSDE is a middleware technology, and it is not able to store spatial data, its role can be understood as the "spatial expansi
