Overview - From indicators and data processing to EO-based products

It was recognised that single EO datasets rarely meet a particular need for environmental or societal information in isolation, but that it is necessary to integrate several different types of measurement.

This step examined how the EO datasets (from space, aircraft and in-situ) acquired and processed during the previous stages could be fused and/or integrated into one (or several) products to meet the environmental indicators identified and the environment concerns documented in the Conceptual Site Models.

It was necessary to establish a mechanism to assess the data and to consider and decide what EO-based products would be made. Throughout the project, a very extensive product development matrix was generated and maintained for each of the three demonstration sites, which tabulated the stakeholder-driven indicators with the environmental parameters derived from the Conceptual Site Models (CSM) along with the EO data available to the EO-MINERS project.

The matrix clarified which input layers were required to make each possible EO-based product, and stipulated deadlines for data delivery, including their format and the partners responsible. The matrix was used within the project as a decision-making tool to determine the range of EO-based products that were made in EO-MINERS in response to the stakeholder requirements. Furthermore, it helped to prioritise which products were made. It was a transparent method to explain which products were made, and why.

It is important to note that EO-MINERS did not make a product relating to every indicator at each site. This was not possible due to limitations of resources, EO data and time within the project duration. Nevertheless, the generic approach developed (conceptual site models, indicators and the required EO data) can easily be adapted for additional indicators or time series analyses, which could not be targeted in detail during the project life time.

In total, 22 integrated products were developed, based around the thematic areas of land use, air quality, water quality and geohazards. Annex 4 lists all of the products and the associated Indicator, along with the primary EO datasets used to construct the product.

Initial interviews with the stakeholders highlighted that there was a wide range of expertise and understanding. Some already had experience of EO datasets and were users of GIS software while others had no experience of any EO data whatsoever. In order to make the EO-based products understandable to the wide range of stakeholders several product formats we developed. The product formats that were delivered include:

The EO Products were presented to the stakeholders at workshops at the mining sites in the Czech Republic, South Africa and Kyrgyzstan (see 3.3.1). The presentations included displays of the paper maps as well as live demonstrations of, and interactions with, the full range of digital products. In order to provide an overview on the EO product development achievements, a printed booklet was prepared and distributed for each demonstration site that showed the diverse EO products presented at the workshops.
