Development in partnership of Remote Sensing Applications for Territory Management

The development of knowledge, data and tools is becoming a crucial issue for territorial management and develoement. Space technologies (remote sensing, positioning) will be key elements of future territorial information infrastructures.

In order to contribute to these infrastructures, a Regional Space Observatory (OSR : Observatoire Spatial Regional) is being established in the southwest of France.

  1. The first aim of the OSR is to collect and organize in-situ and remotely-sensed data in order to serve pluridisciplinary research works on various environmental issues.

 

  1. The second aim of the OSR is to favor the development of tools and services for territories management through space technologies applications, falling within the framework of the "GMES downstream services". To achieve this goal, partnerships are built between laboratories, end-users (eg. local authorities, decision makers) and private companies. These partnerships are based on the sharing of information.
  • the OSR Started in 2001, labeled by INSU in 2007
Objectives:
  • Research on the functioning of land surface: water and carbon fluxes, land cover/use, crop monitoring, …
  • Calibration/validation of EO algorithms and products
  • Experimentation to prepare new EO missions (SMOS, Venµs, Sentinel 2)
Approach: Long Term Experiment
  • Routine in situ measurements: fluxes at the soil/vegetation/atmosphere interface, LAI, biomass, etc
  • Systematic acquisition of one cloud free high resolution satellite image (SPOT, Formosat) every month since 2002 (now Kalideos site)
  • Partnerships with local actors
  • Distribution of the data through internet OGC services (ongoing work)

 

The Observatoire Spatial Régional (OSR) : satellite data and scientific uses

Example Frame

An innovative concept of "experimental territory" is being developed in the framework of the Pôle d'Application des Techniques Satellitaires (PATS) leaded by the Pays Portes de Gascogne (159 communes of Gers département, 2000 km2). The objective is to experiment pilot services defined with public or private end-users. End-users are mobilized thanks to the dynamics created by the territorial development project. The services are carried out by private companies and/or research laboratories. The main themes currently identified are dealing with agriculture and peri-urban issues. Dynamic mapping of land cover and water management are the first two needs clearly identified.

The construction of a modern way to exchange and operate geo-information between the partners is a cornerstone of the project. Technically, we follow the Open Geospatial Consortium specifications, implementing WSDL based services above UMN Map server for interoperability of information and metadata. We then developed a Web client application in Flex®. The goal is not only to propose another tool for browsing geo-information on the web, but to provide a flexible interface for different users and bring special attention on storage, analysis, and viewing of multi-temporal data.

As a first use case, and according to stakeholder’s interest and capabilities, we are transposing a simple satellite monitoring tool for wheat irrigation into the Web Processing Service specification of OGC. The service will be able to use imagery from any Web Coverage Services server or the client computer and interlock with other processes. Once the WPS structure settled, we will be able to implement another much desired application which is the dynamic land use and land cover assessment.
