From remote sensing imagery to actionable information – tackling real life problems by proven methods and new science


We live in very interesting remote sensing times: As compared to 20 years ago, we have now access to an enormous amount of satellite data, we now can make use of many more data sets such as open street maps and drone imagery, and we can choose between many forms of implementations of remote sensing algorithms – including proprietary software like eCognition, free packages like ESA’s SNAP tools, rich libraries for Python programmers and many other options. Despite this rich set of options, the remote sensing community coming after scientific research has the same challenge as 20 years ago: How to provide actionable information for real life problems.

We want to introduce three different approaches how an application house like Tama Group is addressing this opportunity. Overall, we focus on information consumers in industry, in government and so called ‘prosumers’. We call the three approaches (i) ‘hands on remote sensing’, (ii) ‘hands-off remote sensing’ and (iii) ‘remote sensing under the hood’.

·      For hands-on remote sensing we illustrate the core development process with object-based image analysis software, consisting of five corner stones: “automated input”, “layer generation”, “segmentation”, “classification” and “automated output generation”. We show this process by land cover examples as provided in an end-to-end fashion by a single ruleware developer.

·      For hands-off remote sensing we introduce the concept of ‘information factories’. Besides the development process of the set of algorithms, which we refer to as ruleware, we explain the enormous importance of the ‘problem assessment’ for such information factories, splitting up development work into front-end and back-end tasks.

·      For ‘remote sensing under the hood’ we introduce an implementation for forestry monitoring which allows non remote sensing prosumers like foresters and investors to make use of remote sensing technologies without any knowledge of projections, atmospheric correction and the like. Here, the development process stretches from UX, back-end ruleware to cloud setup and data transfer challenges.

From our perspective, todays increased attention to environmental care and focus on sustainable use of natural resources provides outstanding opportunities for geographers we have not seen in the last 20 years.
