IGiS Server

IGiS Server, a user can control GIS data including imagery through a centralized management system. The services provided by IGiS Server can be used for distributing and sharing the map data to IGiS Web Client over internet/intranet. IGiS Server provides a conducive environment to share maps over a distributed network for the purpose of better data interpretation and analysis.

IGiS Server is configurable with Internet Information Services (IIS) or Apache Web server and supports various industries known RDBMS like ORACLE, Microsoft SQL Server, PostgreSQL, MySQL and ODBC enabled data source. IGiS Server also provides a scalable GIS server platform that can be deployed on a single machine to support small workgroups or multiple departments. You can also deploy IGiS Server on the cloud.

Features of IGiS Server

Customization

IGiS Web Server provides a rich set of Application Programming Interfaces (APIs) to the developer for the purpose of customization. It supports popular scripting and development environments such as PHP, Python, Perl, Ruby, Java, and .NET.

Spatial Database Management

IGiS Server provides the facility to create and manage a spatial database for the purpose of storing and managing spatial data. The database contains the information pertaining to geometry, attributes and spatial references system. IGiS Server manages multiuser database. IGiS Server supports Microsoft®, SQL Server, SQL Server Express, Oracle®, PostgreSQL, IBM®, DB2, Informix® and Dynamic Server.

MAP Services

Support for various types of map services is provided by the IGiS Server. These services are useful for sharing GIS Data over the intranet and internet. All web services supported in IGiS Server conform to the following industrial web standards like OGC & Simple Object Access Protocol (SOAP).

Web Services

Spatial Data replication
Data sharing among multiple users.
Geocode:
It searches and display’s location on a map by finding associated geographic coordinates from data such as street addresses or zip codes.
Geometry
Supports SFA for storage model of geographical data. It is represented as Well known Text (WKT) and Well Known Binary (WKB).
IGiS Globe view:
It containing the 3D environment which includes facility to view real-time 3D terrain.
Raster Data:
Distributing and sharing raster data among users on network.
Keyhole Markup Language (KML):
Support of KML is available. KML has been adopted as an OGC implementation standard.
Mobile Client:
Q-Pad for field data management.
Network Analyst:
Define Network Rules, Applying Turn Impedances, Node impedance, Managing Network Locations, Shortest Path, Location Analysis.
Search:
Provision for searching spatial information.

Versioning

IGiS Server provides versioning capability for GIS data set. It controls and tracks the changes occurring in the database due to multiuser interaction. It maintains only the tracked changes rather than the entire database. Each and every version has a unique identity.

Versioning facility simplifies the work of the administrator by removing the necessity of maintaining separate copies for each database for every user. The changes done by users can be tracked and verified directly by the administrator and after verification the administrator updates the database thereby simplifying the integration process.

Data Interoperability

IGiS Server data interoperability allows the information to be exchanged by coordinating common specifications and standards. It enables us to work with any standard GIS data without any restricted access or implementation.

IGiS Server supports verities of spatial data by its interoperability capability including WFS, GML, KML, DWG/DXF/DGN/DVD, WKB/WKT, and Oracle Spatial.

OGC Services

Web Map Service (WMS)
It is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database.
Web Coverage Service (WCS)
It provides an interface allowing requests for geographical coverages across the web using platform-independent calls. The coverages are objects (or images) in a geographical area, which end-users cannot edit or spatially analyse.
Web Feature Service (WFS)
It provides an interface allowing requests for geographical features across the web using platform-independent calls.
Styled Layer Descriptor(SLD)
It is an XML schema specified by the Open Geospatial Consortium (OGC) for describing the appearance of map layers. It is capable of describing the rendering of vector and raster data. A typical use of SLDs is to instruct a Web Map Service (WMS) of how to render a specific layer.
Geography Markup Language (GML)
It is the XML grammar, defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet.
Sensor Observation Services (SOS)
The OpenGIS® Sensor Observation Service Interface Standard (SOS) provides an API for managing deployed sensors and retrieving sensor data and specifically, “observation” data.
SFA (Simple Feature Access) data support.
Simple feature access (SFA, also called ISO 19125), is both an OGC and ISO Standard that specifies a common storage model of geographical data (point, line, polygon, multi-point, multi-line, etc.) using well-known text (or binary). The geometries are also associated with spatial reference systems. The SFA also specifies attributes, methods and assertions with the geometries.

In general, a 2D geometry is simple if it contains no self-intersection. The SFA specification defines DE-9IM spatial predicates and several spatial operators that can be used to generate new geometries from existing geometries.

Catalogue Service

User can query their stored data with catalogue web service, using AOI by performing the attributes and spatial query. It also provides metadata information.

Search and Indexing

IGiS Server has provision for searching and indexing spatial information.

Geo-processing

Geo-processing uses a GIS vector layer, performs a geometry operation on that data requested by the user, and returns the result of the operation as an output GIS Vector layer.

• Buffer • Union • Intersection • Identity • Update • Eliminate • Dissolve • Clip/Erase • Convex Hull • Thiessen • Merge • Simplify • Overlay analysis

Security Management

Database Management Services:
IGiS Server supports the industry known RDBMS by providing management services to make data centralized and secure.
Secured Distribution of Data
Data distribution among the users is secure and it prevents unauthorized access.

Web Editing

WFS
The OGC Web Feature Service Interface Standard (WFS) provides an interface allowing requests for geographical features across the web using platform-independent calls. The basic Web Feature Service allows querying and retrieval of features.
WFS-T
A transactional Web Feature Service (WFS-T) allows creation, deletion, and updating of features.
IGiS
IGiS Supports a host of feature services that support editing of the database. Using these features enables the users to add, delete and update geographic features over the network.
SFA
Data editing by Simple Feature Access (SFA), geographical data model (Point, Line, Polygon, multi-point, multi-line, etc.) using well-known text (WKT) or binary (WKB). The SFA specification defines DE-9IM spatial predicates and several spatial operators that can be used to generate new geometries from existing geometries. It supports OGC standard schema, contains the metadata information of Geometry column information and Spatial Reference System. Spatial reference systems can be referred to use a SRID, including EPSG codes defined by the International Association of Oil and Gas Producers.
