OGC Standards
We maintain expertise on many standards published by the Open Geospatial Consortium (OGC). Our center of interest is mainly on the Sensor Web Enablement standards (see below) but we also follow closely many other OGC working groups working on web services and encodings: Among the most important are the Web Map service (WMS), an interface for access to imagery and map data for visualization, the Web Coverage Service (WCS) for accessing N-dimensional multi-band datasets and the Web Feature Service (WFS), a well-known interface for publishing vector data in an interoperable manner. We also maintain up to date knowledge on many data formats or encoding standardized by the OGC such as , the Geographic Markup Language (GML), KML, GeoJSON and more. We have extensive experience with conformance to these standards and have implemented using various technologies and programming languages.
Sensor Web Enablement
Our sensor experts are involved in the design and implementation of several OGC standards of the Sensor Web Enablement suite of specifications. The SWE Common Data Model (SWE Common) and the Sensor Modeling Language (SensorML) allow the complete description of measurement systems and their components. The SensorML language takes a processing approach of measurement and lead to unambiguous descriptions of systems that can be understood by both humans and machines. Along with the Observations & Measurements (O&M) standard that describes the observations themselves, it can describe the full chain of measurement from the data collection to the final data delivery. This can be accomplished in an interoperable way so that multiple vendors can build software and infrastructures concurrently while maintaining compatibility. The SensorML language was first developed at the University of Alabama in Huntsville by the VAST Research team where our founder M. Alexandre Robin was heavily involved in its design and the development of various tools and processing software built around the standard. We are also involved in the development of SWE service standards such as the Sensor Observation Service (SOS) that is an simple efficient service for accessing streaming sensor data, the Sensor Planning Service (SPS) for tasking sensor or processing devices, and other services for issuing alerts and notifications.
Web 2.0
We provide consulting and development services to help you design dynamic websites that provide easy and interactive ways to manipulate complex datasets and powerful algorithms. The design of these rich content websites benefit from the latest in web technologies to improve user experience and simplify access to more complex web services. Thanks to recent improvements to well established technologies such as Javascript and DHTML, powerful applications can now be developed to take full advantage of new browsers capabilities. These applications running on the client side can be used to present domain specific data in an interactive and user friendly way without sacrificing efficiency or losing important information. When even more functionality is needed, this new type of web interfaces can also be supported by server-side applications to handle things such as right management or context dependent behaviors. A wide range of users, going from general public to domain experts can then connect and start to use information from a service. Sensia Software is innovating by using these new technologies to connect to your sensor networks and other data sources. We have experience with the following technologies: HTML5, Javascript/JSON, XML messaging and AJAX, XML Stylesheet Transformation (XSLT), Multi-Browser support, and more.
Mobile Devices and Cloud Computing
We also have experience in software development for mobile devices based on Android or Apple OSes, as well as expertise in the different cloud computing platforms available. We have built advanced web applications deployed on Amazon EC2 and Google App Engine.
