iMapInvasives: Web-based Invasive Species Mapping Tool

header-nac09IMAPINVASIVES: A WEB-BASED APPROACH TO INVASIVE SPECIES DATA AGGREGATION, MAPPING, DECISION-MAKING AND ACTION!

Presented at the 36th Natural Areas Conference, “Living on the Edge: Why Natural Areas Matter”, Vancouver, Washington, USA, September 15-18, 2009.

A crucial part of invasive species prevention, early detection and management is having good location information. The New York Natural Heritage Program, the Florida Natural Areas Inventory, The Nature Conservancy and NatureServe are working together to develop an online, GIS-based mapping tool to assist on-the-ground land managers and others working on invasive species. This national prototype will allow users to enter quality-controlled data online, search and view data, run analyses, and create maps and reports. Learn how iMapInvasives serves the needs of those working on invasive species and how you and your partners can participate at a statewide scale

MESSENGER Flyby to Capture Additional Images of Mercury

“As the spacecraft approaches Mercury, cameras will photograph previously unseen terrain, and as the spacecraft departs it will take high-resolution images of the southern hemisphere. Scientists expect the spacecraft’s imaging system to take more than 1,500 pictures. So far, more than 90 percent of the planet’s surface has been photographed. These new pictures will fill in some of the gaps and provide high-resolution imagery of targets of interest.”

Map of the Day: Fugro Robertson Limited’s Plate Wizard

…from the ESRI Map Book, Volume 24

“This map displays an overview of Fugro Robertson Limited’s Plate Wizard project, which encompasses detailed global plate definitions, a dynamic model of plate reconstruction through geological time, a unique deformable plates methodology, geological control information, and a GIS front-end.

“The project has as its starting point detailed global plate definitions, including defined rigid cores and deformable margins. These are based on the detailed regional plate models developed at Fugro Robertson Limited (FRL) over the last ten years, together with a comprehensive analysis of the near global passive margins and oceans gravity and magnetics dataset compiled by Fugro Gravity and Magnetics. This has been used in conjunction with FRL’s global geological database to define a consistent global set of continent-ocean boundary definitions.

“A key aspect of Plate Wizard is the development of a deformable-plates methodology for both convergent and divergent environments. Plate Wizard represents a major advance over the rigid plate models, with all their inherent problems, that have been available so far. The geological control information aspect of the project is feature linked in GIS to supporting databases, including geological control information and references. Finally, the GIS front-end allows full access to the plate polygons and rotation files, detailed browsing, access, reconstruction and deformation of both Plate Wizard and third-party data.

NOAA Visualization of Land and Ocean Surface Temperature: August 2009 One of the Warmest Months on Record

“The world’s ocean surface temperature was the warmest for any August on record, and the warmest on record averaged for any June-August summer season, according to NOAA’s National Climatic Data Center in Asheville, N.C. World-wide records began in 1880. Shown here is a visualization of the August global temperature anomalies–or in other words, how the average temperature in August differs from the average climate of 1961-1990. Notice that in some areas, such as the central United States, temperatures were much cooler than average. But overall, land and ocean temperatures were several degrees above normal.”
