In this paper, we use landscape metrics for land cover and statistical analysis to explore the interactions between such measures as shape and patch density indices for land cover and lake primary productivity. The objective was to identify metrics that could be used to predict lake primary productivity, as measured by chlorophyll a, total nitrogen and total phosphorus estimates. Land cover and landscape metrics for the Toolik region of Alaska were derived using satellite imagery and Fragstats software. The metrics, treated as independent variables in a stepwise regression, were derived for two levels of land cover. The first comprised the entire watershed studied; the second was derived using buffers created around water channels within each watershed. A statistically significant model for each dependent variable was obtained. Results suggest that, of the metrics tested; those related to broad leaf vegetation complexes were most useful in predicting lake primary productivity. The Landscape Shape Index for riparian patches and the Patch Density for heath complex were the two most important metrics for predicting variation in chlorophyll a (p Numéro de notice : A2012-574 Affiliation des auteurs : non IGN Thématique : FORET/IMAGERIE Nature : Article DOI : 10.1559/15230406394187 En ligne : https://doi.org/10.1559/15230406394187 Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=32020

[Termes IGN] WebSIGRésumé : (Auteur) A traditional knowledge “Iñupiaq Web GIS”, based on a five-year study and containing observations and environmental knowledge of Iñupiat communities indigenous to Arctic Alaska, was incorporated into a Web-based platform. The website, “Arctic Cultural Cartography,” was created to be an open portal through which the password-protected “Iñupiaq Web GIS” could be accessed. We discuss the process of developing the web GIS including the incorporation of user-friendly features such as links to interactive maps, video clips of interviews, discussion boards, and the integration of popular web interfaces such as Facebook. We also discuss short- and long-term goals for the further development of the GIS, its potential as a sustainable, participatory online database for sharing pertinent ecological knowledge, and challenges in achieving optimal community involvement given constraints imposed by remote locations with limited bandwidth.

[Termes IGN] WebSIGRésumé : (Auteur) Sea ice data has significant scientific value for climate, environmental impact and engineering studies leading to the construction of facilities in Arctic waters, as well as to support tourism and fishing planning. Large collections of such data are acquired, compiled, produced and maintained by national and international agencies such as the Canadian Ice Service (CIS). Some of these data collections have been made available online. However, current Internet-based sea ice data dissemination practices do not foster easy access to and use of the data, especially given the amount of the archived sea ice data and the nature of their spatial changes and high temporal variations. This article reports a research effort in developing a web-based geographical information system (GIS) that facilitates the access and use of the historical sea ice data. The system provides online access, exploration, visualization, and analysis of the archived data, mostly in the form of ice charts, within a web-based GIS. The results from a prototype development indicate that web GIS, developed using Rich Internet Application (RIA) technologies, provides added values in serving sea ice data and suggests that such a system can better accommodate more advanced sea ice data access and analysis tools.

In 2000, the unmapped areas at a scale of 1:50,000 in the Arctic islands in Nunavut and the Northwest Territories, amount to over 800,000 square kilometres, equivalent to approximately 1,500 map sheets. In 2003, a northern mapping project was launched to complete the topographic map coverage in Northern Canada. In order to explore all possible scenarios, the Centre for Topographic Information – Sherbrooke (CTIS) worked closely with the Canadian Space Agency and the private sector on various feasibility tests. After investigating multiple data sources, the combination of existing aerial photography, LANDSAT 7 ETM+, SPOT5/HRS imagery, interferometric pairs of ERS 1-2 tandem and RADARSAT-2 imagery were chosen for planimetric data and Canadian Digital Elevation Data (CDED) acquisition. In 2004, mapping contracts were carried out on a test site and positive results from these tests initiated the production of the unmapped areas of Canada. The planimetric vector data are available on the GeoGratis Web portal and the CDED data sets are available on the GeoBase Web portal.
