manage spatial information, collectively known as the Data Archive (Repository). As an example of Oracle database-based ARCSDE, the repository contains a data dictionary table, stored procedures, and several. dll files under the SDE user. A data dictionary table that stores metadata information such as feature classes, Feature class fields, feature class projections, feature class scopes, and stored procedures and. dll to implement GIS operations and

pooling of spatial pyramids Overview of the spatial pyramid pooling layer: in the convolution operation of the picture, the size of the convolution core is not changed, the weight of the inverse adjustment is only the value will change. But, however, the size of the input picture can you control it. Haha, the size of our input images will change, where the change in image size does not affect the convolut

First, Introduction Spatialhadoop is an open-source mapreduce extension designed to process spatial data on apachehadoop clusters. Spatialhadoop has built-in high-level language for space, spatial data types, spatial indexes, and efficient space operations. second, installation and configuration Spatialhadoop 1, configuration Spatialhadoop Spatialhadoop designe

Hadoop Foundation----Hadoop Combat (vi)-----HADOOP management Tools---Cloudera Manager---CDH introduction We have already learned about CDH in the last article, we will install CDH5.8 for the following study. CDH5.8 is now a relatively new version of Hadoop with more than hadoop2.0, and it already contains a number of

Chapter 2 mapreduce IntroductionAn ideal part size is usually the size of an HDFS block. The execution node of the map task and the storage node of the input data are the same node, and the hadoop performance is optimal (Data Locality optimization, avoid data transmission over the network ). Mapreduce Process summary: reads a row of data from a file, map function processing, Return key-value pairs; the system sorts the map results. If there are multi

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

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
