The WeObserve project, with the participation of Grumets, is planning to launch its first 3 Communities of Practice on June 6 in Geneva in the framework of the Citizen Science Workshop Day of the 2nd ECSA International Conference (European Citizen Science Association).
The WeObserve CoPs will serve as the vehicle for sharing information and knowledge on selected key thematic topics related to Citizen Observatories (COs), strengthening the knowledge base about COs in order to move citizen science into the mainstream of environmental management and decision making.
In total, WeObserve will develop five CoPs over the course of the project. Each CoP will receive support and tools for managing the CoP activities (online and F2F) and undertaking dissemination and outreach. The CoPs will exist for as long as they provide value to their members, with WeObserve support to draw on for the coming 2 ½ years.
The first three CoPs will be launched this year on the Citizen Science Workshop Day on 6 June 2018. They have the following topics:
The CoPs are intended as a key mechanism to consolidate knowledge on COs inside as well as beyond the WeObserve consortium. As such, a wide range of stakeholders is invited to take part in the CoPs, such as public authorities (local, regional, national, EU), civil society organisations, research and academia, citizens and citizen science working groups. Activities that the CoPs will undertake include thematic knowledge co-creation, generating new solutions or agreeing on how to use existing ones, and knowledge sharing activities (meetings, events, conferences).
Recently, the second update of the Remote Sensing Terminology Dictionary, published on paper in 2012 (with Enciclopèdia Catalana and the Cartographic and Geological Institute of Catalonia) and prepared by Xavier Pons and Anna Arcalís with the linguistic collaboration of Termcat, has been released online. Following the publication on paper, an open access publication was made through Termcat, which was updated some time ago. Now a new update of this version is presented, which includes 48 new terms and 171 modifications. Currently the Dictionary offers 2214 Catalan terms with the equivalents in Spanish and English, plus the corresponding synonyms, which means that there are more than 3000 entries.
It is the most extensive Dictionary (with more entries and with more complete entries) never published in any language on Remote Sensing. With the new update, the Dictionary is well up to date with platforms and sensors that are continually being launched, and also those that are phasing out. The Dictionary is another contribution to the dissemination of science in Catalan, and in this case it is quite deep, given the following characteristics:
The Dictionary is available from the following link: http://www.termcat.cat/ca/Diccionaris_En_Linia/197/. In the introduction to the paper version of the Dictionary you can find other virtues of the work described. We hope it will be useful to you.
The third prize of the OGC Inspire Hackathon that took place this Thursday March 22 in Orleans under the INSPIRE Conference has been for the map browser developed by Grumets within the EcoPotential project. The browser incorporates the geospatial user feedback, also developed by Grumets in the NextGEOSS project. Double recognition, therefore, for the work done, congratulations!
On Wednesday February 14 at 11 a.m., the defense of the PhD thesis of the Grumet Juanjo Vidal-Macua will take place in the Hall of the Faculty of Arts and Humanities of the UAB. The thesis has been directed by the Grumets Xavier Pons, Miquel Ninyerola and Alaitz Zabala and is titled Analysis of determining factors of forest transitions and the abandonment of crops in the Mediterranean. A model of land cover dynamics based on Remote Sensing, GIS and Boosted Regression Trees.
Grumets Joan Cristian Padró and Xavier Pons attended the conference TerraEnVision - Environmental Issues Today: Scientific Solutions for Societal Issues last February 1st to present the work Evaluation of mine restorations using UAV imagery, by Padró JC, Carabassa V, Balagué J, Alcañiz JM and Pons X. The conference took place in Barcelona.
This newly released 2018 year begins well for Grumets, who start with a handful of new publications on the curriculum. A book and four indexed articles collect the recent work of Grumets in the fields of remote sensing and conservation of natural resources, the dynamics and ecology of the landscape, the modeling of energy fluxes and the geometric and radiometric corrections of satellite images. Here you have the references and the access to the works to enjoy them during this 2018:
On December 14, the 16th TIG-SIG Forum, organized annually by the Catalan Association of Geographic Information Technology, took place in Barcelona this year with the motto OpenGeoData. Xavier Pons (UAB) participated in the Forum in a talk about the benefits and dangers of the "Open" world, together with Ms. Lourdes Muñoz, of the BCN chapter of the Open Data foundation. The forum allows the meeting with actors in Catalonia from consolidated or emerging companies, large and small administrations and research institutions dedicated to geographic information.
A new edition of the journal GeoFocus, edited by Grumets, is now available. It is the 20th edition, and you can read it in the following link:
We hope it is of your interest!
The indexed journal Forest Ecology and Management has just released a paper on forest dynamics written by Grumets. The work, Factors affecting forest dynamics in the Iberian Peninsula from 1987 to 2012. The role of topography and drought, is authored by Juan José Vidal-Macua, Miquel Ninyerola, Alaitz Zabala, Cristina Domingo-Marimon and Xavier Pons, and analyzes the role of structural factors and the influence of the occurrence of periodic events in the evolution of forest ecosystems in broad areas around the Mediterranean fringe of the Iberian Peninsula. The study provides robust evidence that drought occurrence plays an important role in the decline of conifers and the expansion of broadleaves, which could become the dominant species in many areas of the Mediterranean if climate model forecasts are met.
The paper is available in open access: http://www.sciencedirect.com/science/article/pii/S037811271730960X
The Grumets Joan Masó (CREAF) and Alaitz Zabala (UAB) won on September 5 in Kehl (Germany), as part of the annual conference INSPIRE Conference 2017, the second place in the Hackaton “INSPIRE Hack 2017”, with a project aimed at improving the INSPIRE data through the collaboration of users, by the generation of evaluations. The project competed with 10 other international projects, all of them aimed at incorporating new types of data or new technologies into INSPIRE.
Grumets Joan Masó and Ivette Serral (CREAF) are going to be next week in Washington DC to attend the XIV GEO Plenary and the side events and exhibitions organized. The known Geo Week 2017 will take place from October 23rd to 27th and Grumets will have a relevant presence there. Here are the activities where you can find them.
The GIS and remote sensing software MiraMon, developed by Grumets, is now free for the Spanish and international educational community. After 23 years of constant evolution and improvements, MiraMon wants to take a step forward and become an international leader. To achieve this, the team and its creator, Xavier Pons, have decided that MiraMon is free since this September 2017 for the educational community around the world: educational centers, related entities and students..
This step places MiraMon among the pioneers of free-use remote-sensing software and adds the tool to the list of Geographic Information Systems (GIS) that opt for free use.
MiraMon has traditionally been widely used in various instances of the Catalan Administration and of other Spanish and worlwide regions, as well as in multiple Universities, research centers, high schools and in outstanding masters and postgraduates of GIS and Remote Sensing. With the aim of continuing to promote its use in the educational segment, MiraMon is now free for students and educational centers, or entities affiliated with educational centers, from all over the world. This measure represents an important step in the will of MiraMon to become a widely used GIS in teaching and in training and educational activities at all levels and represents a distinctive element in the world of remote sensing software.
"We have made this commitment with the intention of extending its number of users, not only in Spain, but throughout Europe and the world”, comments Xavier Pons, Professor of Geography at the Universitat Autònoma de Barcelona (UAB) and CREAF researcher, creator of MiraMon.
"With this decision our pioneering remote sensing softwares position from a full GIS integration continues through gratuity and we add to other GIS that already offer their programs at no cost”, concludes.
This fall is full of congresses for Grumets. From the presence in the Geospatial Sensor Webs 2017 in late August to the AGE Congress at the end of October, several Grumets will present this autumn the latest work of the group in national and international events of relevance. Below you can see the details to know where to find us next months:
During the week of March 20 to 24 a new meeting of the OGC Technical and Planning Committee de l'Open Geospatial Consortium (OGC) is taking place in Delft (Netherlands). As in past editions, Joan Masó has an active participation in this meeting, in which he also acts as representative of other Grumets. You can find him as co-chair or as participant in the working groups on Architecture DWG, Citizen Science DWG, Electromagnetic Spectrum DWG, Web Map Service SWG, OWSCommon SWG, OWSContext SWG, Hydro DWG and DataQuality DWG.
In addition, during this week the approval as a Public Engineering Report of the following documents with participation of Grumets will be discussed:
Last January 17th the members of Grumets Miquel Ninyerola and Meritxell Batalla presented in Andorra the second version of the Digital Climatic Atlas of Andorra (ACDA), related to the new reference period 1981-2010 and created jointly with the Centre for the Study of Snow and Mountain of Andorra (CENMA).
The presentation included an informative talk with two different parts. One about the methodology and characteristics of the new ACDA, and a second one about the interesting derived uses and applications, since the Government of Andorra uses the ACDA data as official data.
For more information you can consult the press release prepared for the event (catalan).
From Thursday December 1st Grumets are involved in a new European project: NextGEOSS. It is an H2020 research project which was presented to the call "SC5-20-2016: European data hub of the GEOSS information system", and which is lead by Deimos Portugal. The project title is "Next Generation GEOSS for Innovation Business (NextGEOSS)" and has a duration of 3.5 years. Grumets will develop a user interaction service (user-feedback) which will be integrated in the European Data Hub developed within the project. This will consolidate the metadata and standards research line developed by Grumets for years, in line with other projects we have done (and continue doing). The research team is formed by Alaitz Zabala (as IP), Xavier Pons and Joan Masó (as collaborator).
Last November 10th GRUMETS participated in the 15th Forum TIG/SIG organized by ACTIG and ICGC with the title Cloud GIS. The program of the conference can be found here, and below the participation details of Grumets:
13:30 -11:45 - Round table: ‘Pros and cons of cloud and geoinformation’
Chair: Irene Compte, Anteverti
Participants: Dr. Xavier Pons, UAB. Aitor Calero, ESRI. Jorge Sanz, CARTO. João Pedro Fernandes, Hexagon.

The next days October 26th-28th Joan Cristian Padró will be in Berlin (Germany) presenting a work from Grumets to the EUFAR / ESA Expert Workshop on Atmospheric Correction of Remote Sensing Data, which will take place in the Harnack House of the Max Planck Society. This is an expert workshop on atmospheric correction of remote sensing data. The aim is to put in touch experts and young researchers involved in remote sensing to present, discuss and review the methods currently used in the process of atmospheric correction. Joan Cristian Padró will present the work "Pseudo Invariant Areas and its benefits for radiometric correction of satellite images".
This work describes that the research group Grumets uses an automatic radiometric (topographic + atmospheric) correction model for sensors in the solar spectrum, like those of Landsat series (L4-TM, L5-TM, L7-ETM+ and L8-OLI) and Sentinel (S2A-MSI). The terrain effects are corrected taking into account the solar incidence angle, cast-shadows, etc. modeled on the basis of a Digital Surface Model of higher resolution than the imagery. Atmospheric effects are corrected using pseudoinvariant areas (PIA), automatically detected from the 12 year time-series Terra-MODIS MOD09GA product, Sun-earth distance, etc. A geostatistical criteria assures radiometric stability of these areas through all bands of involved sensor (OLI, ETM+, ...) during all the time-series, generating a bank of PIA useful for all the time-series.
On 9th September ended the 17th edition of the Master in Remote Sensing and GIS with the ceremony of reading the Master Theses. We want to congratulate the 18 students who have successfully completed this year and will have the opportunity to continue with a PhD or a job in the companies and administrations dedicated to this sector, as well as to thank its commitment to all the teachers and organization staff.
On 28th September we start the 2016-2017 edition of the Master, with 19 students newly registered and 4 more applying for recognition of previous degrees or enroling in the Master Thesis. The vacancies offered are 20 for students doing all the Master, plus 7 for students asking for recognition of previous degrees. Thus, the registration data for this year has again been successful.
About the newly registered students and their origin, 9 of them come from Catalan universities (UB, UdL, UdG UPC), 5 come from Latin America (Chile, Ecuador, Colombia and Argentina), 4 from other Spanish universities (UIB, UGR, UV and USAL) and 1 from the University of Milan. About their academic profiles, 6 are graduated in environmental sciences, 5 are geographers, 3 are forest engineers, 2 are geologists, 2 are topographers and 1 is a biologist.
Barcelona will host, from 26th to 30th September, the actual edition of the conference on the implementation of the European Directive INSPIRE:INSPIRE Conference 2016, organized by the European Commission and the Cartographic Institute and Geological Survey of Catalonia (ICGC), that will address the shared use of environment applied geographic data.
In parallel to this act, the VII Iberian Conference on Spatial Data Infrastructures (JIIDE 2016, 27th to 30th September) is held as an engine to drive and help to definitely realize the environmental orientation of the IDE and contribute to demonstrating their usefulness in responding to the environmental problems we are facing. The theme chosen this time for the VII Conference is: "IDE: an ecosystem of resources for a sustainable environment."
Both events will be held at the Palau de Congressos de Barcelona (Av. Diagonal, 661-671, 08028 Barcelona, metro stop Zona Universitaria).
Within the framework of these two conferences, the research group GRUMETS presents several communications:
Xavier Pons and Joan Masó are the authors of the article A comprehensive package open format for preservation and distribution of geospatial data and metadata, recently published in the journal Computers & Geosciences in Open Access. The paper describes the evolution of the MMZ format for compression and distribution of geographic data to the format MMZX, improved and appropriate to ensure the preservation of this type of information.
The idea of the MMZ was conceived and implemented in 1997-98 thanks to the boost given by the Generalitat of Catalonia. The MMZ has been really helpful for geographic information distribution for the Administration, universities and research centers, businesses, students, etc., and won the second place of the Möbius International Award to the best application in science and technology in Internet on the year 2000.
The new MMZX format keeps the idea and the spirit of the original MMZ, but above all it improves the former through taking a format based on an ISO specification (specifically 29500-2, Open Packaging Conventions, or OPC) to convert it not only in an open format, but also to an standardized one and with a number of additional properties, such as the support to different entry points of the "maps" (map project) for the different formats, proprietary or free, which may contain, or the inclusion of thumbnails of the map itself.
The idea, which might seem initially overcome by the modern geoservices (WFS, WCS, WMS / WMTS, KML, etc), takes a renewed strength for the added repesenting contribution to the preservation of data following the needs marked by the preservation standard Open Archival Information System (OAIS). Indeed, the MMZX can be used, with its great simplicity of creation and use, to save time frozen "versions" of maps used for an investigation, an administrative process, legal, etc; and also with the sophistication of supporting different data models, metadata, symbolization, etc. which are generally not allowed simultaneously by other alternatives. The use of the specification ISO 29500-2 as a geographic information preservation format (the underlying MMZX idea) could also be introduced in the new candidate standard ISO 19165, entitled "Geographic information - Preservation of digital data and metadata" that is still in the early stages of discussion. We will continue working for keeping it in future revisions.

The paper Developing spatially and thematically detailed backdated maps for land cover studies, by the Grumets Juan José Vidal-Macua, Alaitz Zabala, Miquel Ninyerola & Xavier Pons has been definitely published in the International Journal of Digital Earth in Open Access.
The main objective of this article is to lay the groundwork for the production of time series of highly detailed land cover maps of large areas. Four land cover products have been obtained with a high spatial resolution (30 m) using Landsat TM and ETM+ imagery, each with a legend of 13 categories derived from a filtering process of the SIOSE 2005 database. The methodology includes a retrospective analysis used for identifying pseudo-invariant pixels along the time series in order to obtain training and test areas in periods lacking reference information. The classification scheme is composed by a non parametric hybrid model which includes several MiraMon modules, and configuration of these modules is justified with several testbeds. The workflow is completed with a collinearity analysis of the variables used: reflectance bands, vegetation and moisture indices and topo-climatic indices. An overall accuracy of over 92% was obtained for all maps and more than 90% of the total area was classified. The framework of this study is a larger project whose aim is to map land cover dynamics in the Iberian Peninsula over a period of decades, so the implemented techniques are very useful to handle the problems related to data volume and backdating.
