A few further requirements for the check were: numerical certainty, alignment-free, absolute hardware reference, and universal application between production and metrology. Thus was the InoraSRS (Spatial Refer
MySQL 9.2.0では、この問題を解消するために新しい動的権限であるCREATE_SPATIAL_REFERENCE_SYSTEMが導入され、SUPER権限を必要とせずに、カスタムSRSの作成・置換・削除ができるようになりました。空間参照系は空間データを扱う上で非常に重要な概念であり、以前のブログ記事(英語)でも説明したよう...
5.4.1 MDSYS.CS_SRS Table The MDSYS.CS_SRS reference table contains over 900 rows, one for each valid coordinate system. Note: You should probably not modify, delete, or add any information in the MDSYS.CS_SRS table. If you plan to add any user-defined coordinate systems, be sure to ...

GeoRaster空间参考系(spatial reference system, SRS)是GeoRaster对象中元数据的一部分。空间参考(Georeferencing)是用来构建像素坐标系与真实世界的大地坐标系(或其它一些本地坐标系)之间双向的映射关系。 Georeferencing不同于几何校正(geocorrection)、校准(rectification)和正射校准(orthorectification)。后面三种处理经常需要...
To be the same, they also have to be in the same SRS. Each SRS is assigned an identifier, the spatial reference system identifier (SRID). For the two points to match, not only must X and Y coordinates match, but the SRIDs of the two points must also be the same. In fact, MySQL...
Using the CREATE_SPATIAL_REFERENCE_SYSTEM Privilege Let’s look how to use this privilege to create a new SRS. Step 1 - Granting the privilege:First, an administrator grants the CREATE_SPATIAL_REFERENCE_SYSTEM privilege to a user. As an example, we’ll grant it to a user named Bob on l...
