For lightweight GIS applications, on time and space with the ability to select a cloud database and then with open source GIS software to quickly build a stable, cheap and practical GIS solutions. Ganos Ali cloud self-study time and space infrastructure (PaaS layer) core engine that integrates heterogeneous parallel computing on the cloud acceleration, OSS and other large-scale storage infrastructure capacity, upper and RDS PostgresSQL database, POLARDB for PG / Oracle Cloud native database, HBase big data integration for cloud computing infrastructure products provide a free professional-grade but spatio-temporal data storage, query and analysis and calculation capabilities.
This article describes how to Ganos as a data source GeoServer, uDig, QGIS etc. The most commonly used open source GIS software docking, to provide support for open source GIS application program selection.
Support for common major open source GIS software
Ganos due to the design of fully compatible interface to PostGIS, so in theory you can seamlessly support various types of software ecosystem of PostGIS.
Select some popular open source GIS software described in the following table:
| Open source GIS software | Software localization | use | Ganos role |
|---|---|---|---|
| QGIS | C ++ - based desktop GIS | Data visualization, management, editing, analysis, and production of printed maps, full-featured | Postgis form compatible data source |
| Geoserver | GIS server software | Publish map data, the feature allows the user to update the data, delete, insert operation, easy sharing of Spatial Information | Postgis form compatible data source |
| uDig | Java-based desktop GIS | Desktop GIS and development framework, Internet GIS, web map server and the network server has a special function to strengthen | Postgis form compatible data source |
| OpenJUMP | Java-based desktop GIS | Built-in map editor, visualization, GIS spatial analysis and other operations, and can customize or extend the functionality through plug-ins | Postgis form compatible data source |
| MapNik | Based on Python / C ++ map rendering engine | Data in the form of a map defined by a stylesheet rendered into bitmap format to provide services such as WMS | Postgis form compatible data source |
More focused on the most commonly used geometric objects GIS (vector) part, be noted that, Ganos in addition to compatible PostGIS capabilities, other high temporal and spatial characteristics of the grid, DEM, point cloud, the network, such as the track can get through with these software . For these needs, you can get support directly through the end of the article contact.
Simple connection configuration, plug and play
The following to QGIS, GeoServer, OpenJump, uDig for example, display interface with application to Ali cloud PostgresSQL Ganos or POLARDB Ganos as the data source, based on other data sources driven PostGIS open source software 3S etc. Similarly, not start one by one.
First, you need to purchase by Ali goes home RDS PostgresSQL, POLARDB for PG or POLARDB for Oracle instance (see end of text links, which POLARDB for PG / Oracle application currently available for free beta), and import vector data via SQL insert or shp2pgsql tool. After the data import, you can view data imported through the console comes with DMS tools:
Next, based on Ganos data sources, the use of open source GIS software to perform all kinds of operations.
(1) QGIS connection Ganos, browse, view, edit, analyze spatial data in Ganos.
(2) GeoServer connection Ganos, vector data can be published as WMS, WFS and other services, rapid application sharing geospatial data.
(3) OpenJump connection Ganos, browse, view, edit, analyze spatial data in Ganos.
(4) uDig connection Ganos, browse, view, edit, analyze spatial data in Ganos.
Not the same as the base, more powerful capabilities
PostGIS via compatible interfaces, Ganos have almost plug and play, eco-compatible capabilities, and is compatible with all PostGIS code will work without modification. Meanwhile, Ganos by fusion with Ali cloud infrastructure, provide more than self PG + PostGIS higher system stability and reliability, more powerful data processing and data processing larger scale, especially in the space-time trajectory data processing capability, than 50-100 PostGIS native improve performance. Follow Ganos will follow OGC specifications, adapting more types of data, including broad support for open source and commercial 3S different platforms, gradual basis of spatial and temporal precipitation cloud computing to cloud computing based platform, enabling ISV vendors to promote cloud computing space and time as digital transformation Pratt & Whitney engine basis to more customers.
