Collaborative custodianship through collaborative cloud mapping : challenges and opportunities
Collaborative custodianship refers to an arrangement where a number of custodians work together to produce integrated datasets for a spatial data infrastructure (SDI), e.g. local authorities contributing address or street data to a national SDI dataset. Collaborative cloud mapping allows for ubiquitous, convenient, on-demand, configured and tailor-made mapping with resources shared between various entities collaborating on a specific initiative, such as an SDI or for disaster management. This paper presents the results of a workshop in South Africa during which case studies from the Netherlands, Belgium and Austria of collaborative custodianship of address data were presented, and OpenStreetMap as a case study of collaborative cloud mapping. Subsequently, challenges and opportunities for implementing similar initiatives in the context of the South African SDI were debated in break-away sessions. The results from these sessions were analysed using the PESTEL framework
APEX CO(3-2) observations of NGC6822
We observed the CO(3-2) emission of the emission-line regions HubbleI,
HubbleV, HubbleX, Holmberg 18, and the stellar emission-line object S28 in
NGC6822 with the ESO Atacama Pathfinder Experiment (APEX) 12m telescope as part
of its science verification. The very low system temperature of 130-180K
enabled us to achieve detections in 4 single pointings and in a high spatial
resolution 70''x70'' map of HubbleV. We compare the spectra with HI
observations, obtained with the Australia Telescope Compact Array, of the same
regions. In combination with previous multi-line CO observations, we perform a
preliminary investigation of the physical conditions in HubbleV using a simple
LTE model. We estimate the mass of the HubbleV region and the H_2/I_CO(3-2)
conversion factor. Also, we show that HubbleV is located very near the
line-width versus size relation traced by the Milky Way and LMC molecular
clouds.Comment: 4 pages, 3 figures, accepted for publication in the Astronomy &

Mesures de contrainte dans la vallée d'Aspe
Une mĂ©thode de mesure de contraintes par surcarottage est dĂ©crite. La cellule utilisĂ©e pour ces essais permet d'obtenir quatre mesures de dĂ©placements diamĂ©traux, perpendiculaires entre eux deux Ă deux, et huit mesures de dĂ©placements longitudinaux le long de quatre gĂ©nĂ©ratrices diffĂ©rentes. Les rĂ©sultats obtenus lors d'une campagne de mesure sont traitĂ©s globalement, aprĂšs quâaient Ă©tĂ© Ă©liminĂ©es les mesures entachĂ©es dâerreurs de manipulation. Ces mauvaises mesures sont dĂ©tectĂ©es en analysant la courbe dĂ©placement-avancement du surcarottage. On est ainsi amenĂ© Ă rĂ©soudre un systĂšme linĂ©aire surdĂ©terminĂ©, problĂšme qui est traitĂ© par la mĂ©thode des moindres carrĂ©s. Un critĂšre complĂ©mentaire est proposĂ© pour Ă©carter de la collection de mesures admissibles, celles qui ont Ă©tĂ© influencĂ©es par la prĂ©sence de discontinuitĂ©s locales.Les rĂ©sultats obtenus lors de trois campagnes de mesure dans diffĂ©rents tunnels sont prĂ©sentĂ©s. Ils font ressortir la nĂ©cessitĂ© de n'effectuer des opĂ©rations de surcarottage qu'Ă des distances de la paroi libre au moins Ă©gales au rayon de la section transverse du tunnel
