The Vespucci 2020 Vision for Digital Earth: Social and Institutional Issues
WHAT IS PARADISE? “Nel mezzo del cammin di nostra vita mi ritrovai per una selva oscura ché la diritta via era smarrita. Ahi quanto a dir qual era è cosa dura esta selvaggia e aspra e forte che nel pensier rinova la paura! Tant'è amara che poco è più morte; ma per trattar del ben ch'i' vi trovai, dirò de l'altre cose ch'i' v'ho scorte. ”
Virtual Globe = (def) digital collection of data and services contextualized within a global (spatial? ) view of a world Virtual Collaborative Globe = virtual globe that allows collaborative participation
TODAY´S VIRTUAL GLOBES Virtual Globes Open. Street. Map Wikimapia
Today´s Virtual Globe limitations 1. 2. 3. 4. 5. 6. No current state of the earth (time is missing and data comes from diverse sources) No exploration inside the building Data is not generally accessible No indication of data provenance No interaction between people (including sharing of data) No indication of trust and quality
GISCIENCE PROVIDES CRUCIAL LINKS BETWEEN NATURE AND SOCIETY Nature: Physical equations Describe processes Society: Decisions on how to Use Earth´s resources
THE 2020 VISION FOR DIGITAL EARTH: SOCIAL AND INSTITUTIONAL ISSUES 1. Maximize open access and participative infrastructures 2. Produce information to address digital divides 3. Enable multiple connected globes/infrastructures 4. Deliver data, services and models tailored to communities of practice. 5. Emphasize societal benefit areas (e. g. , ecosystems, health) 6. Be based on environmental-friendly technologies 7. Use Digital Earth as a laboratory for multi-disciplinary science
OPEN ACCESS AND PARTICIPATIVE INFRASTRUCTURES Ideal: spatial data available as open access and shared between communities Practice: Need to overcome institutional barriers
OPEN ACCESS AND PARTICIPATIVE INFRASTRUCTURES What did we learn from our fathers? A penny saved is a penny earned
OPEN ACCESS AND PARTICIPATIVE INFRASTRUCTURES LANDSAT data archive (USGS) The Anti-Uncle Scrooge Principle A pixel unused is a penny wasted
OPEN ACCESS AND PARTICIPATIVE INFRASTRUCTURES The cost of data distribution in the Web is zero Uncle Scrooge and the Web: value comes from use!
WHAT IS A PUBLIC GOOD? Non-rival. . . [goods] which all enjoy in common in the sense that each individual's consumption of such a good leads to no subtractions from any other individual's consumption of that good. . . (Samuelson) Non-excludable it is impossible to exclude any individuals from consuming the good
Almost all spatial data are public goods
OPEN ACCESS AND PARTICIPATIVE INFRASTRUCTURES STRM 90 x 90 m ASTER-DEM 30 x 30 m
“Scientists have models for estimating the amount of carbon released into the atmosphere when a given plot of land is razed. This information can now be extracted fairly accurately from satellite images. Access to information will be critical. A few satellites can cover the entire globe, but there needs to be a system in place to ensure their images are readily available to everyone who needs them. Brazil has set an important precedent by making its Earth-observation data available, and the rest of the world should follow suit. ”
OPEN ACCESS AND PARTICIPATIVE INFRASTRUCTURES: SOME PREDICTIONS FOR 2020 Global satellite data in 5 meter+ will be open Geodemographics analysis widely available Official spatial data will be mostly open Citizens and global forces are drivers of change
INFORMATION TO ADDRESS DIGITAL DIVIDES Ideal: communities know what affects them, promote positive changes and react to negative prospects Practice: communities have limited knowledge about their territory and its potential futures
INFORMATION TO ADDRESS DIGITAL DIVIDES The goal of development is the promotion and expansion of valuable capabilities. Capability is the freedom to achieve valuable beings and doings. (Amartya Sen)
Impacts of global environmental change By 2020 in Africa, agriculture yields could be cut by up to 50% sources: IPCC and WMO
INFORMATION TO ADDRESS DIGITAL DIVIDES How to promote and expand valuable capabilities in Digital Earth? Practice: Open source and open access promote capacity building Caveat: OS and OA are not substitutes for sound research
ENABLE MULTIPLE CONNECTED GLOBES The Earth is a system of systems
ENABLE MULTIPLE CONNECTED GLOBES Institutional portals (e. g. , GEOportal) Contribution-based portals (e. g. , Google)

Open Globe (def) collection of trusted spatial data and services, available operationally and reliably on a open access policy
Open Globes Virtual Globes Open. Street. Map Wikimapia
Open Globes Virtual Globes Data + services (can only be provided reliably by organizations that are trusted) ? visibility, communication, acessibility Scientists as policy-makers (peer-reviewed results) Citizens as sensors (perception, individual actions)
