Abstract:

Several studies are presented focused on the use and potential of geomatics (basically Remote Sensing and Geographic Information Systems) for assessing different landscape features and vegetation key environmental variables as providers of Environmental Services (ES) at different spatial and temporal scales.

We will start presenting three case studies where structural variables of vegetation and terrain landscape features were quantified at a detailed scale from imagery taken by consumer grade cameras on board of Remote Piloted Aircraft Systems (RPAS) and also by low resolution airborne LIDAR.

In the first case analyses were based on structure from motion image analysis and object oriented classification of digital surface models and orthomosaics in order to classify and measure trees, hedges and agricultural terraces in olive plantations in South Spain.

In the second, LIDAR pulse filtering and subsequently image thresholding, filtering and Morphological Spatial Pattern Analysis (MSPA) were performed for the classification of hedgerows in a traditional Bocage landscape in the North West of Spain.

With regard to coarse scale assessing of ES, we present two applications of Remote Sensing for the assessment (quantification and spatial-temporal monitoring) of forest and grassland biomass and productivity in Central and South America, by means of low and medium resolution RS and different statistical/modelling techniques.

We will also draft experiences on the multi-scale pattern analysis of five ES related to the amount of biomass, computed from collections of medium resolution RS imagery in the NW of Spain. Finally the potential of hidrochemisty of mire waters combined with geodata for the multi-scale assessment of environmental impacts (land use, industrial pollution) will be outlined based on a case study in NW of Spain.
