ISO/TC211standards supported
| Standard number | Standard name | Introduction to standards |
| ISO 6709:2008 | Standard representation of latitude, longitude, and altitude for geographic point locations | Standard representation of latitude, longitude, and altitude for geographic point locations |
| ISO 19101-2:2008 | Reference model—Part 2: Imagery | This paper describes the use environment, the basic principles and the reconstruction framework of the GIS standard, and also defines all the concepts and elements of the standard. The standard provides the framework of 191 ** family standards. |
| ISO 19103 | Conceptual Schema Language | Conceptual Schema Language. The standard makes users aware of UML, primitive types, and objects Constraint language used in ISO/TC211. |
| ISO 19104:2008 | Terminology | This paper defines all the special vocabularies used in ISO/TC 211standards. Its purpose is to produce a common vocabulary related to geographic information standards for the use of standard setters, users and developers of geographic information systems. |
| ISO 19106:2004 | Profiles | Defines a subset of all ISO/TC 211standards. It defines the method and reference manual for extracting a specific subset of standards for specific applications on the basis of all ISO/TC 211standards. |
| ISO 19107:2003 | Spatial Shema | Define the conceptual schema of the spatial features of objects, mainly from the perspective of geometry and topology. Geometrical entity and topological relation are two main features of geographic information. Their standardization will provide convenience for other spatial feature standards and help GIS developers and users to understand spatial data structure. |
| ISO 19108 | Temporal Subshema | To define the concept of temporal scale feature of spatial entity, geographic information is not limited to three-dimensional scale, and many geographic information systems need temporal feature. The iServer supports the concepts in the standard in the processing of time-aware data. |
| ISO 19109 | Rules for Application Schema | Define the schema for geographic information applications, including the classification of geographic objects and the principles for their relationship to the application schema. Defining application schemas in a consistent form will enhance the ability to share data between applications and allow applications to interact in real time. |
| ISO 19111-2:2009 | Spatial referencing by coordinates | A model for the conceptualization of a coordinate spatial reference system is defined, as well as guidance describing a geodetic reference system, which also includes a number of internationally used reference systems. The development of a coordinate spatial reference system also facilitates communication and data-sharing between various applications. |
| ISO 19112:2003 | Spatial referencing by geographic identifiers | The conceptual model of the indirect spatial reference system is defined. ISO recognizes that more and more applications of geographical information use non-coordinate type reference systems, that is, indirect spatial reference systems, such as address data, so it is necessary to produce a standard model of indirect reference systems. |
| ISO 19115:2003 | Metadata | A standard for defining descriptive information for geographic information and services. The purpose of this standard is to produce a geographic metadata content and related standards. These contents include the current situation, accuracy, data content, attribute content, source, coverage area and adaptability to various applications of geographic data. The standard description of geographic data makes it convenient for geographic information users to get the applicable data. |
| ISO 19115-1 | Metadata-Part 2: Fundamentals | Metadata elements and schemas (i.e., datasets and services) that describe the geospatial are defined. |
| ISO 19115-3 | Metadata — Part 3: XML schema implementation of metadata fundamentals | Provides a schema for implementing ISO 19115 -1 in XML. |
| ISO 19117 | Portrayal | The method of geographic information description is defined, and the consistent symbol representation method is used between different application systems, which will be convenient for people to better understand and identify all kinds of geographic information. |
| ISO 19118 | Encoding | The encoding rules that match the conceptual schema used by the geographic information are selected, and the mapping modes between the conceptual schema languages and between the encoding rules are defined. The coding rules make the geographic information coded according to a certain coding language and system when it is stored and transmitted in digital form. |
| ISO 19119 | Service | Identify and define the service interfaces of geographic information and the relationship with the Open System Environment model. The definition of service interfaces helps various applications at different levels to access and use geographic information. The metadata portion of the standard has been moved to ISO 19115 -1. The concepts defined in this standard are used by iServer at the time of the OGC W * S specification. |
| ISO 19125-1:2004 | Simple feature access-Common architecture | A generic architecture for simple feature geometry based on concepts from the ISO 19107 is described. |
| ISO 19125-2:2004 | Simple feature access-SQL option | The standard specifies an SQL schema that supports simple geospatial storage, retrieval, query, and update operations. |
| ISO 19128:2005 | Web Map Server interface | A service is defined for rendering a spatially referenced digital image map dynamically derived from geographic information for display on a computer screen. |
| ISO 19131:2007 | Data product pecifications | Requirements for geographic data product specifications are provided. These include application architecture, spatial and temporal reference systems, quality and data acquisition, and maintenance processes. |
| ISO 19136:2007 | Geography Markup Language | The standard provides an XML encoding and XML schema syntax that allows an open, vendor-agnostic framework for defining geospatial application schemas and objects for storing and transporting application schemas and datasets. |
| ISO 19139:2007 | Metadata—XML schema implementation | Provides encoding rules and schemas for ISO 19115 in XML |
| ISO 19142:2010 | Web Feature Service | A Web service is defined that provides direct, fine-grained access to geographic information at the feature and feature attribute levels. |
| ISO 19143:2010 | Filter encoding | The standard describes system-independent XML and kay-value pair (KVP) encodings for representing projection, selection, and sorting clauses, collectively known as query expressions. |
In addition, the GeoRSS specification is supported.
In order to meet the needs of different scenarios and a variety of software and improve the utilization of data, SuperMap supports the generation and release of standard tile packages, so that the existing tiles can be reused directly without conversion, avoiding duplication of work and intensive use of resources. SuperMap supports standard tiles, including:
The following security protocols are supported:
HTTPS (full name: Hyper Text Transfer Protocol over Secure Socket Layer) is a security-targeted HTTP channel. All GIS services, management functions, service aggregation and cluster systems provided by SuperMap support HTTPS protocol.
LDAP (Lightweight Directory Access Protocol) is widely used, and many server systems use LDAP servers to store user accounts. SuperMap supports the use of user accounts from existing LDAP servers without the need to duplicate the creation of users. In this way, the GIS system can share a set of user system with other application systems in the organization unit, which can not only reduce the duplication of investment in the construction of user system, but also avoid the redundancy of user system in the organization.
SuperMap supports the use of third-party accounts under the OAuth 2.0 protocol, such as QQ, Sina Weibo, and WeChat accounts. These third-party accounts can directly log in to the GIS server or bind to existing accounts in the GIS server. In addition, SuperMap supports third-party account login under all OAuth 2.0 protocols by extension.
