National Spatial Data Infrastructure Act- Japanese Legislate to Advance Geo-information
In May 2007 a new bill on National Spatial Data Infrastructure was enacted by the Japanese government, aiming to provide a legal framework for the development and distribution of geo-information based on GIS and Space-Based Positioning, Navigation and Timing (PNT).
MÉTA: Multi-Attributed Vegetation Database of Hungary
Traditional vegetation mapping faces new challenges: much larger survey areas, new habitat categories for uncharacteristic or degraded vegetation, increased number of ecological attributes and new methodological standards. The Hungarian MÉTA field-based vegetation-mapping project has risen to the challenge with a triple-level spatial database.
GIS in Response Time Analysis
Response time is key to fire fighting. Urbanisation and changes in land use demand continual assessment of the spatial distribution of fire stations and fire risk within the framework of costs/benefits. Since these problems have a spatial component, GIS systems are being used to solve them. The author demonstrates through a case-study in the Dutch city of Zutphen the capabilities of GIS in optimising location of fire-stations. |

GNSS: Evolution or Revolution
The market for Global Navigation Satellite Systems (GNSS) has never looked so buoyant. Are we in the midst of a revolution or simply witnessing evolution pre-planned and destined to run its course? Two fictional respondents, the revolutionist and the evolutionist, here answer four pertinent questions.
Mapping the Oceans- Indian Naval Hydrographic Department
With long experience in the production of navigational charts, nautical publications and electronic charts, today the Indian Naval Hydrographic Department (NHD) is well equipped to meet national and international requirements and naval defence needs. The author opens the door on these activities.
3D Modelling of Castles- Integrating Techniques for Detail and Photo-realism
3D documentation of heritage buildings is important for conservation, restoration and education. When it comes to complex architectural structures such as castles, no single modelling technique is capable of yielding cost-effective, highly detailed and accurate photo-realism. The authors demonstrate how integration of multiple techniques brings resolution. |

 Explore the Softer Side of GIS
According to Joseph Berry, although computer-based procedures supporting desktop mapping seem revolutionary, the idea of linking descriptive information (what) with maps (where) has been around for quite awhile.
What Are the Implications of Maps 2.0?
With the advent of Web 2.0 functionality, the time seems right for people to develop their own mapping datasets. Using "crowd-sourcing," or the harnessing of collective efforts, it’s now feasible to construct quality spatial datasets that are available as free and open-source software (FOSS).
New Specifications Seek CAD/GIS Standards
Today’s GIS professionals are increasingly more tech-savvy than ever before, with many individuals proficient in advanced technology for complicated 3-D graphics. These professionals often use computer-aided design (CAD) tools to create, communicate, and archive CAD and GIS models. |

GEO TIMES (Feb 2008)
 Oil Around the World
Geotimes examines the latest in oil exploration and production in the standard and not-so-standard oil-producing countries of Norway, Iraq, the South China Sea, India and Libya.
Africa: A New Frontier in Oil and Gas Exploration
Africa is relatively underexplored for hydrocarbons despite the continent’s rich natural endowments of oil and gas. But new developments are starting to bring these resources online.
Improving Evolution Education
The United States leads Western nations in ignorance about evolution. One way to remedy this situation is for geologists to get more involved in writing and editing textbooks.

American Surveyor (Feb 2008)
 Point to Point: Compromising Positions
There are few surveyors who are excited by the prospect of discussing insurance of any form, and health insurance in particular. I count myself among that group. Nevertheless, something has happened in the last few years of which you should be aware, but I have discovered that hardly any surveyors know of it.
A Private VRS Network Takes the Strain Out of Phoenix Surveying
The basic idea behind the Trimble VRS network is that AZGPS's reference stations continuously send data to a central server, and the server continuously calculates area and atmospheric corrections for the region covered by the network.
Laser Scanning: DARPA Urban Challenge
Uptake of laser scanning technology in automotive and other mass markets promises to be the breakthrough that in time will let prices of terrestrial laser scanning technology come down dramatically as well as driving new levels of product robustness and compactness.
Education in Crisis - The Elephant That No One Sees
The lack of mathematical ability of students taking post-secondary surveying education is but the smallest tip of a socialized education iceberg. |
