Image service provides a new mode of image data management and release, that is, large-scale image or raster data management and rapid release through service (image service), which will change the original way of "managing image data and graphics through desktop software, and then publishing image maps through SuperMap iServer". It greatly improves work efficiency.
The image service provides the capability of quick publich service for massive images, and supports the publishing of multiple Server types: REST, WMTS, WMTS-China, and WMS; Image data management capabilities, including adding images, deleting images, and querying and retrieving images.
There are the following ways:
Configure the service name, service description, and datasource where the image collection is stored.
"Datasource for storing image collection" is used to store image collection mosaic dataset in the service; it is recommended to create a new PostGIS or PostgreSQLData source.
The image service uses image collections to manage images. Multiple collections can be added to the service.
Image collection uses the mosaic dataset model to manage image metadata, and the corresponding mosaic dataset is created when the collection is created.
The collection mosaic dataset is stored in the image service's store datasource for image collection, which is specified when the service is created.
When publishing the image service, it is not included to set the image data content. After the service is created successfully, add the image through the "New Collection".
Highlight:
1. Different service instances cannot be configured with the same datasource save set mosaic dataset.
2. "Datasource for storing image collection" is not set. It is a temporary UDBX datasource by default, which is located in the program installation directory. When the program is upgraded, it is not convenient for the migration of image collection. And UDBX datasource is not applicable to concurrent operations of image management. Database-type datasource is recommended.
Select server type, and multiple selections are supported; REST image service (OpenAPI image service) is the default published server type.
Whether the image service allows editing and downloading images. Turn on "Editable" to allow adding and deleting images in the image collection or collection; turn on "Downloadable" to allow downloading images in the service.
After the configuration is complete, click publish to create an image service. At this point, the service has not set image data. You need to go to the service management page and continue the "New Collection" operation to add images for the service. See: Add Image to Imaging Services .
Image service does not support multi-process configuration.
