• Ana Loureiro added an answer:
    Is there a scale (could be a short scale or some items) for evaluating the perceived naturalness of scenes (e.g. landscape, neighbourhoods, gardens)?

    this is for a pretest of some fotographs of houses (with and without plants nearby) and gardens (with more or less plants and other natural elements).

    we want to find out which of the stimuli are evaluated by participants as being most natural and which are least natural.

    I'm not talking about scales like Perceived Restorativeness Scale.

    I am referring to the Lang (1980; see also Bradley & Lang, 1994) SAM scale (for arousal and valence/pleasure), adding complexity and type of environment  (natural or urban).

    How do I perform an image difference between TM and OLI vegetation index layers?

    I'm currently trying to find the change in value between two dates for a couple vegetation indices generated from two different types of Landsat data. The first image is a TM image from 2011 and the second is a 2013 Landsat 8 OLI image. Both images are georegistered and converted to atmospherically corrected TOA values. While doing some preliminary investigating, I found that the values for unchanged landscape features are significantly different between dates. I'm wondering if this is a result of the difference in radiometric resolution between the sensors (8bit vs 12bit). The Landsat 8 values appear to be lower in a number of areas compared to the TM. Whats should I do to accurately difference the images?

    Khatir Benhanifia · centre of spacial techniquess

    If the study aimes to compare spectral values in different times, in this case atmospherical calibration is mandatory. Even if it aimes to establish change detection supervised post classification of NDVIs guves acceptable results.

    Is there any survey that critically assesses the pedagogical position behind different Intelligent Tutoring Systems?

    Intelligent Tutoring Systems are very important in current landscape of AIED. However, I am not able to find papers discussing the pedagogical positions behind different ITSs in a critical way. 


    Krishnan Umachandran · Professor

    No tutoring system can be as intelligent without a "real tutor interface". All IT enabled teaching and learning systems are confined to a particular set of knowledge base attached to it, being probed by a "Keyword search" or a "string search" options into the knowledge database.
    Over a period of implementations it can be fine tuned.

    with regards to motivation, it should be an economical advantage to the "content contributor". However, in a business model, the content provider is paid and forgotten as the site goes alive and the technical team takes charge of support and maintenance.

    Which are the best journal articles and books on green infrastructure?

    I am working on my doctoral dissertation on Green Infrastructure of the Rural Settlement and its Surrounding Landscape, while considering all components of the rural green infrastructure - (green spaces in school gardens, cemeteries, church gardens, town centre, streetscapes, lakesides, accompanying vegetation of watercourses and roads, trees at objects of small sacral architecture in the landscape, etc.). I have done literature reviews and bibliographical research since 2012 but I do not want to miss any good recent journal articles or books. Do you know some? Maybe you have recently published something on the same or similar issue.

    What role does effective landscapes play in the sensory development of children with Autism?

    Improvising and narrowing down my previous research question to get a better clarity

    Anthony G Gordon · Independent Researcher

    "Children with sensory sensitivity should not be exposed to sensory-challenging environments that use artificial stimulation, to answer Anthony's question."

    I do not think the answer to this question is simple, or that it can be answered theoretically.  Empirical data are needed.   Do we say that a congenitally deaf child should not be exposed to weak and distorted auditory input?   An adult with a vestibular disorder will do better by exposing themselves to vertiginous environments in order to learn compensatory strategies.

  • How might forest and farm producers best be represented in the myriad multi-sectoral platforms that decide things on their behalf?

    The Forest Farm Facility is strengthening forest farm producer organisations - in part to help them engage in decision-making (see attached report) - but what experience do you have about which platforms it is best to engage and how (Food Security, REDD+, FLEGT, landscapes etc) ?

    Gonzalo Galileo Rivas Platero · Instituto Interamericano de Cooperación para la Agricultura

    The multisectoral platforms should facilitate processes of representation and define the roles of the participants according to their expectations, needs and interests. The platform itself is a learning space where they can diagnose problems, identify opportunities and ways of solving problems. To that producers have representation, we must make them part of your environment, take initiatives, defining the focus of the platform, identify options to solve a problem, test and refine solutions, build capacity and implement pe innovations that can generate in the process.

  • Mark Anderson added an answer:
    How do people come to value utilitarian infrastructure, and respond to (threats of) its removal?

    I have a number of research cases at present that are converging on the same phenomenon: that some utilitarian infrastructure (factories, towers, dams, dykes) change the landscape in substantial ways that are not intended to be beautiful - sometimes even protested at the outset - but that over time these become emblematic or enablers of sense of place, identity and lifestyle. They become perceived as public goods, requiring maintenance, despite the decline in its original utility. Does anyone know of other published examples of this phenomenon, or know of theories that relate to it?

    Is this phenomenon not a good example of what behavioral economists either call endowment effect or call status quo bias?  The classic reference would be:

    What is a good measurement of solar radiation/insolation for use in landscape level analysis?

    I've looked into Fu & Rich and their ArcMap solar rad points tool. Any advice would be helpful!

    I'd like to evaluate the effect solar radiation has on aspen regeneration across three national forests in Utah. I have about 180 sites that I have 2 years of veg data for. Preliminary analysis has shown that Elevation is an important predictor of aspen regeneration, and I think that solar radiation would also explain some of the variance and that simple analysis of slope and aspect alone are not sufficient to capture the effect that solar radiation has on microsite conditions..


    Chris Gueymard · Solar Consulting Services

    The Fu & Rich model is terribly inaccurate and should not be used for serious work. The r.sun model in GRASS GIS is much better, but still approximate

    Historical irradiance data at a maximum spatial/temporal resolution of 90m and 30-min are also commercially available. Please contact me.


  • How can I calculate with GIS landscape units that are spatially self-contained?

    A self-contained unit landscape is a portion of the territory where physical barriers limit and frame the view of the observer. The observer feels he is in a territorial compartment visually differentiated.

    Pedro Miguel Ramos Arsénio · University of Lisbon

    I think Joan Negre's answer is helpful but what about background slopes that, although outside the drainage basin, are visible from inside the basin? I mean, there's a foreground (and those areas should be inside the drainage basin) but there's also a visible background (and if you need to consider these visible areas outside the drainage basin, the hydrology tools are not enough.

    Maybe if you start by the drainage basins and them locate a grid of observer points inside, in order to estimate its viewshed, you will get closer to what you need.

    Nevertheless, I still think its important to use a surface model rather than a relief model.

    Hope this helped, good luck!

    Are agricultural landscapes emergent structures?

    I wonder whether agricultural landscapes can be described as emergent structures. Are they more than their individual components (crops, forests, hedgerows, orchards and meadows)? 

    Is there some work about emergence and agricultural landscape?

    What are the properties that one can describe from agricultural landscape emergence?

    Linh Quang Nguyen · Hue University

    Dear Colleagues,

    As you see, in Agricultural systems showed different components (out & in; major and extra), so the value of landscape emerges under structure by nature or human. It's component play a role in the system and they contribute in different function into the final outcomes; So we can made a model:

    Y = a1x1 + ......anxn = Alpha +beta + gama +- Sima ax.................

    So we can calculate for each component and show in the landscape emerges and see the outputs and outcome, but there is important thing, we can manage the system how to get output > input and keep environment in safe way for human, nature and resources.

    So landscape emerges under structured by experts for sustainable development and keep the values in benefitary ways for labors/famers and companies/cooperatives.

    How much is landscape scale?

    Does anyone knows how much can be landscape scale in numbers? it is common to see references about landscape scale but I do not know about references that define numerical scale of landscape scale. May be this 1:250.000? 1:500.000.

    Frederico Mestre · Universidade de Évora

    I think that the landscape scale is dependent on the scale at which the focal species operates. For example small mammals explore the landscape in a much more finer detail than large predators. As connectivity is dependent on the dispersal ability of the species, I think that the "landscape scale" is dependent upon the home range.

  • Saif Uddin added an answer:
    Is the use of artificial grass really green?
    Large scale greenery projects are implemented in middle east for past two decades. Recently, synthetic grass is largely used replacing natural grass. Makes some sense largely the maintenance cost, natural grass use to burn at 50oC temperature we have for couple of months in summers and the synthetic survives. Is it environmentally sound, pro climate change mitigation?
    Saif Uddin · Kuwait Institute for Scientific Research
    I am in agreement with Kam and Dr. Mohammad. I myself dont see environmentally sound reasons to adopt it. But those pushing for thsi change put cost of irrigation, the grass in this part of the world is burnt in 50oC temperature that exist for 3 mo and thsi is taken as a solution. The other issue wich is quite likely to come is from waste management perspective. after the end of life of these turfs they are going to land in landfills in huge quantalies. Other issues are related to rummer crumbs that are used as infills in third generation turfs.

    I am working on an extended inner area having a broad minor historical heritage but a negative trend of population growth. I am interested in studies dealing with regions in demographic crisis and development strategies for these areas.
    Jeffrey de Fourestier · Carleton University
    You are right. However in the case of eastern parts of Germany it is largely an economic issue. The Soviet Union was a big economic supporter of the old GDR. So when they left, the employment and cash input they provided left as well. Since the old GDR economy could not compete with its West German counterparts the work was to be found either in the large centers in the former GDR or in the western parts of Germany. Without investment locally these towns have seen their young skilled labour move out and only older retired people who cannot easily move stay behind.
