An example of how to realize the aggregation animation effect of vector streamlines based on GeoToolKit/INT

Continuing on the basis of the previous article, the same data processing method is used to unify the data formats of strata of different ages (currently, the formats supported by js parsing include ZMap, TS, XYZ, and XYZA, etc.). This article is mainly based on the GeoToolKit/INT component. In view of geological research, which often […]

Use the MyBatis type converter to convert the geometry field in PostGIS to the geometry Java object of PostGIS/GeoTools

An overview In actual GIS project development, PostGIS is often used to store vector data, and geometric fields are created in PostGIS to store spatial geometric information. Corresponding to the Java server, we hope that the corresponding table entity (MyBatis) directly uses geometric objects to store data. Operations, such as using JavaType such as org.postgis.Geometry […]
