Marginal Lands (MLs) could offer suitable carbon sinks by afforestation/reforestation projects without being competitive to food production, conforming to EU/Global policies. The main objective of MAIL is to trigger utilization of MLs as Carbon Sinks by activities related to forestry and agriculture. The project aims to detect and classify mountainous and semi-mountainous Marginal Lands (m/sm MLs), in order to deliver a web-based regional platform with data, methodology and applications which will be valuable for policy makers, stakeholders or researchers.

MAIL will assess MLs’ presence, distribution and suitability in smart and efficient way, considering that marginality differs within European bioclimatic zones. It will detect MLs through multiple layer analysis of existing EU/Global scale datasets (land cover, land use, soil or climatic information, etc.) and will further examine, validate and classify MLs, through field stratified sampling, into Carbon sequestration capacity categories.

In pilot areas MAIL will augment the achieved accuracy by using enhanced spatial and radiometric resolution of full free and open access satellite datasets. Furthermore, it will propose actions that have to be taken in order to increase Carbon sequestration capacity and it will evaluate their feasibility by using a set of criteria for accurate cost estimation. Finally, it will deliver developed methodologies, algorithms and techniques on a web-application platform for on-demand production of thematic maps within Europe.


  • Definition of parameters describing Marginal Land within the different European climate zones, as MLs are affected by latitude.
  • Implementation of certain series of data processing in order to determine the best possible way to map/monitor m/sm MLs based on free available datasets, satellite data or open source applications.
  • Quantification of potential CO2 sequestration capacity and sustainable utilization of MLs under the prism of LULUCF.
  • Alternative proposals of possible vegetation species that might be used for CO2 storage on MLs considering the limited site conditions. To test the effectiveness of the methodology of the project, the approach will be applied in pilot case studies, representative of Mediterranean and Central/Central-Eastern Europe.
  • Creation of a knowledge base and a virtual web classroom for the training of participants in advanced classification remote sensing techniques.
  • Creation of a virtual place where partners, stakeholders or research community, could collaborate and find useful information.
  • Establishment of a permanent working team consisting of RS and Forestry experts that will focus on the MLs management at EU level.
  • General guidelines and manuals will attract and help relevant stakeholders. The pilot work will prove the feasibility of MAIL results. The project will focus on initiating the supply chain, analyzing, describing and implementing possible planting and harvesting methods as well as logistic concepts.

  • Principal Investigator: Luis A. Ruiz
  • Duration: 30/12/2016 – 29/12/2019

Wildfire prediction and behaviour models require more precise information concerning forest structure, in particular that concerning understory vegetation. New data acquisition techniques should be adapted to provide the right information at affordable costs, and allowing for the integration of data acquired at different scales. The main goal of this project is to explore methods to acquire and process LiDAR data and other emergent terrestrial and aerial remote sensing techniques to a higher level of detail, to develop methods for the estimation of forest fuel variables required in the new models of fire prediction and behaviour, and to integrate them for the design of efficient protocols, data processing and analysis, and their application to the characterization of fuel potential.

For this purpose, new methods for LiDAR full-waveform processing will be developed, and their potential for understory vegetation characterization in Mediterranean areas evaluated. The potential of terrestrial laser scanner as a reference measure will be analysed, as well as its complementarity with hemispheric photography systems. Cloud points generated by optical cameras and low-cost UAS-LiDAR systems will be analysed and processed for the generation of canopy structural variables. Parameters obtained using different technologies (aerial and UAS-LiDAR, TLS, hemispheric cameras, dense image matching-UAS) will be tested for fuel modelling and wildfire behavior.


  • Increase LiDAR full-waveform applicability by exploring its potential to characterize understory vegetation
  • Study the potential of TLS as reference and calibration of understory aerial measurements, and complementarity with hemispheric photography
  • Acquisition and processing of point clouds from UAV optical cameras (SfM) for using in fuel and fire behavior models
  • Analysis of potential of low-cost UAS-LiDAR sensors for high detail (hot spots) forest structure characterization:

Remote sensing to coastal changes in order to mitigate climate change impacts [CGL2015-69906-R]

  • Financed by: Ministerio de Economía y Competitividad
  • Partners: Universidad Politécnica de Valencia
  • Principal Investigator: Josep E. Pardo-Pascual
  • Duration: 01/01/2016 – 30/06/2019

Beaches are an environmental, social and economic resource of high importance that can be threatened by sea level rise caused by climate change. For minimizing the impact of these changes it would be necessary to study the response of the beach to different factors. To obtain response models that consider sea rise level sea and coastal storm situations specific information is required being expensive and complex to get for all the beaches since this information (bathymetry, slope, beach material texture) changes over time and energy conditions to which they are subjected.

This project aims to use the massive data related to the large series of medium-resolution images (such as Landsat and Sentinel-2) to characterize the evolution of the beaches in large areas obtaining key parameters that allow to analyze how climate change affects to the beaches.

In this project we propose to apply an own algorithm -Shoreline Extraction from Landsat Imagery, SELI- already published and used in previous work as basis for deriving new information using multiple archive Landsat images (series 5, 7 and 8) and those that are being registered by active satellites such as Landsat (7 and 8) and the new European satellite Sentinel-2 (in orbit and operating since June 2015). This set of data will allow us to characterize the evolution of the beaches and to obtain relevant information being expensive for large areas such as the slope of the beachfront or beach material texture.

Another objective of this research is to take advantage of some improvements in Landsat 8 satellite (new band 1 for coastal applications) trying to obtain bathymetry of shallow water next to the coast. To do this the classic algorithms will be applied to Landsat 8 images in a more efficient and accurate way according to the already published results. The bathymetric information-and its variation due to the waves- is extremely important to predict the response of the beaches to rough weather or sea level rise. In addition, all this information may be important to understand how populations of some species living in these highly changing environments are evolving.

The results obtained in this project can be of great interest to environmental, social and economic management of Spanish beaches, particularly for the Mediterranean ones. If objectives were reached, key information for beaches will be obtained (evolution and morphosedimentary features) in an quick and global way with lower costs what could face new and more rigorous studies on areas not yet analyzed.

The analysis of forest structure is crucial for biomass estimates and carbon flux monitoring, for forest inventories, and for forest fuel mapping as input in wildfire risk models. Methods using LIDAR (Light Detection and Ranging) for forest structural and fuel variables estimation have an operational use, however, some aspects must be solved: (i) the development of LiDAR full waveform processing methods, with more potential for structure study; (ii) methods for cartography of forest inventories and management, and stratification of structural types using LiDAR and imagery, (iii) the procedures to improve estimates of diameters at plot level by developing models, (iv) the estimation of fuel attributes using LiDAR full waveform; (v) the estimation od errors in prediction models at small stands levels; (vi) the acquisition configuration and possibilities of TLS; and (vii) the integration of data and models. As a result of these goals and actions, tools useful for forest management at national level are developed, to contribute for the improvement of wildfire prediction and fire behavior.


  • Development of specific tools for LiDAR full-waveform processing and analysis
  • Development and evaluation of methods for the stratification of structural fuel types from LiDAR, high and medium resolution satellite imagery using object-based analysis

Development and Integration of Methods for Land Use/Land Cover Database Updating [CGL2010-19591/ BTE]

  • Financed by: Ministerio de Ciencia e Innovación and FEDER
  • Partners: Universidad Politécnica de Valencia (UPV-CGAT)
  • Principal Investigator: Luis A. Ruiz
  • Duration: 01/01/2011 – 31/12/2013

Land use/Land cover (LULC) databases are essential information for applications such as natural resources or territory management and landscaping. Their maintenance is expensive and the updating rate must be dynamic. New LULC database updating procedures based on object-oriented methods for feature extraction, classification and change detection, were developed and evaluated. Image analysis methods were focused on the extraction of information from cartographic objects (parcel, plot) at the spectral, textural, structural, shape, intra-object and inter-object levels. The use and quality requirements of LiDAR data was analysed for extraction of 3D structure of landscape elements. Object-oriented change detection and classification techniques from a multivariate and multiscale perspective were evaluated in three landscape strata: urban, agriculture-forestry, and mixed areas.


The goal of this project was to develop, integrate and evaluate new LULC database updating procedures, based on object-oriented methods for feature extraction, classification and change detection, integrating a wide spectrum of georreferenced data and facilitate the progressive automatization of the spatial database updating tasks. In addition, multiscale thematic generalization methods were studied from a multiscale perspective in order to optimize the use of available data and their mutual relationship.
