United States Thoroughfare, Landmark, and Postal Address Data Standard FGDC-STD-016-2011 Part 2: Address Data Content Link Part 2 defines address elements, their attributes, and address reference system elements. Address, data content
United States Thoroughfare, Landmark, and Postal Address Data Standard FGDC-STD-016-2011 Part 3: Address Data Classification Link Part 3 classifies addresses according to their syntax, that is, their address elements and the order in which those elements are arranged. Syntax determines the record structure needed to hold and exchange an address, and often it is all that is known about the addresses in a given file. Classifying addresses by syntax rather than semantics (i.e. meaning) allows users to focus on record structures and avoid making any assumptions about what Address Feature Type the address might identify. Address, data classification
United States Thoroughfare, Landmark, and Postal Address Data Standard FGDC-STD-016-2011 Part 4: Address Data Quality Link Part 4 helps users assess the quality of their address data. It provides ways to measure the quality of each element, attribute, and classification. Some measures compare values to Address Reference System (ARS) specifications or domains of values, while others check internal consistency. Measures describe ways to discover anomalies, in isolation, in relationships between data, and in relationship to the ARS, and how to report the quality of the data. Address, data quality
United States Thoroughfare, Landmark, and Postal Address Data Standard FGDC-STD-016-2011 Part 5: Address Data Exchange Link Part 5 provides: (1) a template for the XML documents and metadata for data exchange; (2) information on preparing address data to be packaged; and (3) information on unpackaging address data. By providing a single flexible data structure for exchanging street address data, the Address Data Standard simplifies implementation of data exchange, making it less likely to need changes over time. Frequently, data exchange programs and reports must be rewritten along with those changes. The Address Data Standard aims to minimize local changes when upgrading computer systems and provide a structure that can be reused by all parties without implementing something new. The Address Standard is designed to be flexible enough to fit within current data sharing methods. There are two basic forms of sharing data: (1) monolithic, in which all records are in the exchange package and (2) transactional, in which the exchange package records include commands to add or remove a record from the local copy of records. The Standard supports both of these forms. Address, data exchange

OpenGIS® Sensor Planning Service Implementation Specification, version 1.0.0 [OGC® 07-014r3] Link Sensor Planning Service (SPS) defines an interface to task any form of sensor or model. SPS enables a client to determine collection feasibility for collection requests for one or more mobile sensors/platforms, or a client may submit collection requests directly to these sensors/platforms. Using SPS, sensors can be reprogrammed or calibrated, sensor missions can be started or changed, and simulation models executed and controlled. The feasibility of a tasking request can be checked and alternatives may be provided. SPS implementations cover a wide range of application scenarios. SPS is currently used to control assets such as simple web cams and satellite missions. This standard should be used for the development of any system that requires the ability to task any form of sensor or model.

Unified Model Language (UML) 2.2 Link UML is a standardized general-purpose modeling language for software engineering. The Object Management Group (OMG) created UML and manages it.  UML includes graphic notation techniques to create visual models of software-intensive systems. UML
Geopolitical Entities, Names, and Codes (GENC) Standard (GENC) version 2 Link The GENC Standard specifies a profile of ISO 3166, Codes for the representation of names of countries and their subdivisions. This profile addresses U.S. Government requirements for recognition of the national sovereignty of a country; identification and recognition of geopolitical entities not included in ISO 3166; and use of names of countries and country subdivisions that have been approved by the U.S. Board on Geographic Names (BGN).

The US Government cannot use ISO 3166 directly. US Public Law 80-242 (1947) requires the US Government to use geographic names that are approved by the BGN. ISO 3166 contains some country and subdivision names that vary from those approved by the BGN. The geopolitical entities included in ISO 3166 are those that are recognized by the United Nations (UN). The GENC Ed1.0 is the US Government implementation of ISO 3166-1 that conforms to BGN and US Government recognition policy. The National Geospatial-Intelligence Agency has developed a country codes registry to maintain the data content of the GENC.

INCITS/ISO 19157:2013[2014] Geographic information -- Data quality Link ISO 19157:2013 establishes principles for describing the quality of geographic data. It defines components for describing data quality; specifies components and content structure of a register for data quality measures; describes general procedures for evaluating the quality of geographic data; and establishes principles for reporting data quality.

ISO 19157:2013 also defines measures for evaluating and reporting data quality. It applies to data producers who provide quality information to describe and assess how well a data set conforms to its product specification and data users who determine whether specific geographic data are of sufficient quality for their particular application. ISO 19157:2013 does not attempt to define minimum acceptable levels of quality for geographic data.

OGC GeoPackage 1.0 [12-128r10] Link OGC GeoPackage 1.0 defines GeoPackages for exchange and GeoPackage SQLite Extensions for direct use of vector geospatial features and/or tile matrix sets of earth images and raster maps at various scales.

Direct use is the ability to access and update data without intermediate format translations in an environment (e.g. through an API). It guarantees data model and data set integrity and identical access and update results in response to identical requests from different client applications. GeoPackages are interoperable across all enterprise and personal computing environments and are particularly useful on mobile devices like cell phones and tablets.

OGC GeoPackage 1.0 has been deprecated.

Geospatial Positioning Accuracy Standards, Part 3: National Standard for Spatial Data Accuracy, FGDC-STD-007.3-1998 Link The objective of the National Standard for Spatial Data Accuracy (NSSDA) is to facilitate sharing and interoperability of geospatial data through a statistical and testing methodology for positional accuracy of maps and geospatial data derived from sources such as aerial photographs, satellite imagery, or maps. The NSSDA omits accuracy metrics or threshold values that data must achieve; however, agencies may establish "pass-fail" criteria for their product standards and applications and contracting purposes. Ultimately, users must identify acceptable accuracies for their applications. While this standard evaluates positional accuracy at points, it applies to geospatial data sets that contain point, vector, or raster spatial objects. data quality, positional accuracy  
Geospatial Positioning Accuracy Standards, Part 4: Architecture, Engineering, Construction, and Facilities Management Link PART 4 provides accuracy standards for engineering drawings, maps, and surveys used to support planning, design, construction, operation, maintenance, and management of facilities, installations, structures, transportation systems, and related projects.

INCITS/ISO 19123:2005[R2011] Geographic information - Schema for coverage geometry and functions Link ISO 19123:2005 defines a conceptual schema for the spatial characteristics of coverages. Coverages support mapping from a spatial, temporal or spatiotemporal domain to feature attribute values where feature attribute types are common to all geographic positions within the domain. A coverage domain consists of a collection of direct positions in a coordinate space that may be defined in terms of up to three spatial dimensions as well as a temporal dimension. Examples of coverages include rasters, triangulated irregular networks, point coverages and polygon coverages. Coverages are the prevailing data structures in a number of application areas, such as remote sensing, meteorology and mapping of bathymetry, elevation, soil and vegetation. ISO 19123:2005 defines the relationship between the domain of a coverage and an associated attribute range.

INCITS/ISO TS 19139:2007 [2015] Geographic information - Metadata - XML schema implementation Link ISO/TS 19139 provides a spatial metadata XML (spatial metadata eXtensible Mark-up Language (smXML)) encoding and an XML schema implementation derived from ISO 19115. It provides a common XML specification for describing, validating and exchanging geographic metadata. It is intended to promote interoperability through a concrete implementation specification. XML schemas will be derived directly from the harmonized ISO 191XX UML master model. Scripts for performing the transformation from UML to XML are referenced. This process follows guidelines defined by ISO 19106, provides dataset implementation and extension examples, and provides an abstract conformance test suite. Although ISO/TS 19139 describes geographic metadata for datasets, the XML schema allows schemas to be applied to datasets, aggregations of datasets, geographic features, feature attributes, feature types, and feature attribute types, etc. While specifics of non-dataset usage of the XML schemas defined here are outside the scope of this specification, these XML schemas are designed to support these types of implementations.

OpenGIS® Web Feature Service Implementation Specification, version 1.1.0 [04-094 ] Link This document describes OGC Web Feature Service (WFS) operations on geographic features using HTTP as the distributed computing platform. It adopts the same concept of a geographic feature as in the OpenGIS® GML standard, wherein a geographic feature is described by a set of feature properties where each property can be thought of as a {name, type, value} tuple. The name and type of each feature property is determined by its type definition.
This document outlines the protocol to process web feature service requests. Processing requests proceed as follows:
1. A client application requests a capabilities document from the WFS. This document describes all operations that the WFS supports and a list of all feature types that it can service.
2. A client application (optionally) makes a request to a web feature service for the definition of one or more of the feature or element types that the WFS can service.
3. Based on the definition of the feature type(s), the client application generates a request as specified in this document. The request is posted to a web server.
4. The WFS is invoked to read and service the request. When the WFS has completed processing the request, it will generate a status report and hand it back to the client. In the event that an error has occurred, the status report will indicate that fact.

OpenGIS® Web Map Context (WMC) Documents Implementation Specification, Version 1.1.0 [05-005] Link Web Map Context is a companion specification to the OGC Web Map Service Interface Implementation Specification version 1.1.1, or "WMS 1.1.1." WMC shows how to describe a grouping of one or more maps from one or more map servers in a portable, platform-independent format for storage in a repository or transmission between clients. This description is a "Web Map Context Document." A WMC document includes information about the server(s) providing layer(s) in the overall map, the bounding box and map projection shared by all the maps, sufficient operational metadata for client software to reproduce the map, and ancillary metadata to annotate or describe the maps and their provenance. A WMC document is structured using eXtensible Markup Language (XML).

This specification applies to creation and use of documents that unambiguously describe the state, or "Context," of a WMS Client application. Reference is made to normative material from WMS 1.1.1. In some cases, reference is made to the Styled Layer Descriptor specification [SLD].

This specification does not address archival, cataloging, discovery or retrieval of Context XML documents.

OpenGIS® Web Processing Service 1.0.0 [OGC 05-007r7] Link WPS provides client access to pre-programmed calculations and/or computation models that operate on spatially referenced data. It defines a standardized interface that facilitates publishing of geospatial processes and discovery of and binding to those processes by clients. Processes include any algorithm, calculation or model that operates on spatially referenced data. Publishing means making machine-readable binding information and human-readable metadata available for service discovery and use.

WPS provides mechanisms to identify spatially referenced data required by the calculation, initiate the calculation, and manage output so that the client can access it. It is targeted at processing both vector and raster data. It allows a service provider to expose a web accessible process in a way that allows clients to input data and execute the process with no specialized knowledge of the underlying physical process interface or API. The WPS interface standardizes how processes and their inputs/outputs are described, how a client can request the execution of a process, and how output is handled. Because WPS offers a generic interface, it can be used to wrap other existing and planned OGC services that focus on providing geospatial processing services. To achieve interoperability, each process must be specified in a separate document, called an Application Profile.

This document does not specify specific processes that could be implemented by a WPS. This document does not address archival, cataloguing, discovery, or retrieval of information that has been created by a WPS.

Symbology Encoding Implementation Specification 1.1.0 [OGC 05-077r4] Link Symbology Encoding (SE) is an XML language for producing georeferenced maps with user-defined styling. It can be used to portray output of Web Map Servers, Web Feature Servers and Web Coverage Servers. The importance of portrayal of geographic data cannot be overemphasized. Portrayal tranforms raw information into an explanatory or decision-support tool. Fine-grained control of graphical representation of data is a fundamental requirement for any professional mapping community.

WMS advertises a preset collection of visual portrayals for each available data set. While it can provide the user with style options, it can tell the user only the name of each style. It cannot tell the user what portrayal will look like. More importantly, users have no way of defining their own styling rules. The ability for a human or machine client to define these rules requires a styling language that the client and server can both understand.

OpenGIS® Web Map Tile Service Implementation Standard, version 1.0.0 [OGC 07-057r7] Link The Web Map Tile Service (WMTS) Implementation Standard provides a standard-based solution to serve digital maps using predefined image tiles. The service advertises the tiles it has available through a standardized declaration in the ServiceMetadata document common to all OGC web services. This declaration defines the tiles available in each layer (i.e. each type of content), graphical representation style format, coordinate reference system, scale, and over each geographic fragment of the total covered area. The ServiceMetadata document also declares the communication protocols and encodings through which clients can interact with the server. Clients can interpret the ServiceMetadata document to request specific tiles.

The WMTS standard can be combined with other OGC standards and integrated with emerging RESTful applications and "mash-ups".

Web Coverage Service (WCS) Implementation Standard version 1.1.2, Version 1.1 Corrigendum 2 release Link WCS 1.1.2 is used to develop systems that provide access to coverage data. It supports only grid coverages. It provides three operations: GetCapabilities, GetCoverage, and DescribeCoverage. It specifies core requirements for a WCS implementation. WCS extension standards add functionality to obtain a complete implementation.

WCS 1.1.2 does not prescribe support for any particular coverage encoding format. This also holds for GML as a coverage delivery format: while GML constitutes the canonical format for the definition of WCS, WCS 1.1.2 does not require that a concrete instance of a WCS implement the GML coverage format. WCS encoding extensions are designed in a way that the GML coverage information specified in this core is consistent with the contents of an encoded coverage.

WCS 1.1.2 has been deprecated.

Tagged Image File Format (TIFF) Revision Link TIFF is a tag-based file format for storing and describing raster images It provides a rich environment within which applications can exchange image data. This richness takes advantage of varying capabilities of scanners and other imaging devices. Though TIFF is a rich format, it can easily be used for simple scanners and applications because the number of required fields is small.

TIFF can describe bilevel, grayscale, palette-color, and full-color image data in several color spaces. It includes compression schemes that allow developers to choose the best space or time tradeoff for their applications. It is not tied to specific scanners, printers, or computer display hardware. It is portable. It does not favor particular operating systems, file systems, compilers, or processors.

INCITS/ISO 19156:2011[2012] Geographic information - Observations and measurements Link ISO 19156:2011 defines a conceptual schema for observations and features involved in sampling when making observations. These provide models for exchange of information describing observation acts and their results. Observations commonly involve sampling of an ultimate feature-of-interest. ISO 19156:2011 defines sampling feature types classified primarily by topological dimension and samples for ex-situ observations. The schema includes relationships between sampling features (sub-sampling, derived samples). ISO 19156:2011 concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation.

Time-Space-Position Information (TSPI), Version 2.0, (2012-04-05) Link TSPI Version 2.0 standard specifies a core XML schema for encoding spatial, temporal, and accompanying quality assessment characteristics of real-world entities. As US government systems become interoperable, the need to unambiguously encode spatiotemporal data for exchange among systems is paramount. TSPI Version 2.0 is a robust mechanism for expressing spatiotemporal data in XML-based schemata throughout the US Federal Sector. It is designed as a set of reusable data components upon which both GML and non-GML-based XML based schemas can be developed. It specifies a registry-based extension mechanism for development and reuse of additional spatiotemporal XML Schema components. It integrates the XML Schema for the United States Thoroughfare, Landmark, and Postal Address Data Standard, FGDC-STD-016-2011. Encoding, XML  
OpenGIS Web Feature Service 2.0 Interface Standard [09-025r1] (also ISO 19142) Link The OpenGIS Web Feature Service 2.0 Interface Standard (WFS 2.0) applies to systems that have requirements to access or distribute geospatial feature data. A Web Feature Service (WFS) request consists of a description of query or data transformation operations that are applied to one or more features. The request is generated on the client side and posted to a web feature server using HTTP. The web feature server then reads the request and returns results that conform to the OpenGIS Geography Markup Language (GML) Implementation Specification. WFS offers direct fine-grained access to geographic information at the feature and feature property level. Web feature services allow clients to retrieve or modify only the data they seek, rather than an entire file. Open Web Services, Web Feature Services, features
GeoRSS-Simple and GeoRSS-GML Link GeoRSS is a standardized way to encode location in RSS and Atom feeds. It allows users to perform geographic searches on feeds and map information found in feeds. It makes it possible to search with all sorts of geographic criteria. Its location content consists of geometries and related feature descriptions. GeoRSS feeds are designed to be consumed by geographic software such as map generators. GeoRSS promotes interoperability and "upward compatibility" across encodings. GeoRSS-Simple is a very lightweight format that developers and users can add to their existing feeds quickly and easily. It supports basic geometries (point, line, box, and polygon) and covers typical use cases when encoding locations. GeoRSS GML is a formal GML Application Profile that supports a greater range of features, notably coordinate reference systems other than WGS-84 latitude/longitude.

There are no restrictions, limitations, or other constraints that affect promulgation, adoption and/or implementation of GeoRSS. The specifications for GeoRSS-Simple and GeoRSS GML are freely available through www.georss.org.

Aeronautical Information Exchange Model(AIXM) 5.1 Link AIXM 5.1 is a standard exchange format containing hundreds of entities, data types, and relationships used to represent aeronautical data. It is based on International Civil Aviation Organization (ICAO) standards and recommended practices and industry standards requirements for digital data exchange and GIS capability. It provides a mechanism to exchange information applicable to aerodromes (airports), heliports, routes, navigation aids, fixes, instrument approach procedures, instrument departures, standard terminal arrival routes, organizations, units, services, obstacles and airspace. It uses Geography Markup Language (GML) to leverage commercial-off-the-shelf (COTS) tools and web services. Its conceptual model uses the Unified Modeling Language (UML) to define the relationships, behavior, and high level ideas for aeronautical data. It was initially developed by the US Federal Aviation Administration (FAA) and the European Organisation for the Safety of Air Navigation (EUROCONTROL) with support from the international community.
