Expanded Road Database

NAVTEQ (IL, USA) has added five new attributes to its digital road maps: enhanced geometry accuracy, speed limit, special speed situation, variable speed signs and number of lanes. These new attributes are available for North America and Europe. However, local variations in availability occur depending on the level of roadway. The company has also launched full map coverage of Finland's road network, extending its road database to now cover all four Nordic countries. The Finnish database includes 614,177 kilometres of road, covering 304,541 square kilometres of territory and 451 towns and cities. The road network of rural counties and provinces... (read more)

Imagery Database Covering Russia

A new site has been launched as the first stage of the project to create satellite-based imagery database covering the entire Russian territory. These images can be viewed as a photographically precise and updated map with different scales: from large territories to separate streets and buildings. Moscow and Moscow Regions mosaicks have already been created.In future the area cover with space images will be increased, first by including St-Petersburg and Leningrad Region, then European part of Russia and later on of the entire territory. An increased resolution up to 1m will be available to see with respect to towns (currently... (read more)

Global Population Database

EVC has made available the LandScan Global Population Database to the European market. Published by the US Department of Energy's Oak Ridge National Laboratory, this database is developed for population study and was made with GIS users in mind.     Comprised of a worldwide population database compiled on a 30" x 30" latitude/longitude grid, the dataset covers the entire globe excluding Antarctica and is updated for annual release. Included in the database are a robust set of metadata, documentation, and user guides to help you get the most out of this unique and comprehensive tool.     (read more)

Universal Map Database

RMSI (CA, USA), a publisher and distributor of geographic information for the United States, has developed Universal Map: an exhaustive carto-graphy geo-database covering entire North America. The project, demanding technical expertise and the integration of various GIS software platforms, involved developing a very large amount of spatial data with many data layers, requiring automation and customisation of processes to meet timelines and maintain accuracy levels. It involved multiple-step processing of inputs received from the client, such as topology cleaning, attribute data linking, edge matching, etc. Data from more than 1,500 sources was cleaned and organised into approximately one hundred data...

Large Scale Reference Database

A Digital Land-Parcel Infrastructure for France
All users of geo-information require large-scale maps accurate to the metre or even, in urban areas, the decimetre. This, along with anticipated new uses and needs, has driven development of France’s Large Scale Reference (RGE) database. The work has meant rectifying the coordinates of digital cadastral maps to fit existing orthophotos and topographic databases. The Large Scale Reference (RGE) database is a set of consistent and complementary data which serves as a digital mapping-based infrastructure for the whole of France. Thematic data relating to a wide range of applications can be located or updated on the RGE database. Developed, maintained... (read more)

Spatial Database Challenges

Advances in Managing LBS and Framework Data
When providing local information, a location-based service (LBS) exploits the geographical position of the mobile device used to access it. The management of very large spatial data databases requires a focus on production and quality control of data, both framework and for LBSs. Progress has lately been made at two levels: system architecture and knowledge management. Standards are key. Mass-market LBSs have had a number of promising beginnings. However, there is a gap between concept and reality due to shortfalls in several areas. Issues concerning price of suitable handsets and availability of positioning capabilities are currently being resolved. The suitability... (read more)

Linking Geospatial Database with GIS

GIM International Interviews Dr Jayant Sharma, Technical Director Spatial Products, Oracle
The database vendor Oracle Corporation has for a long time shown a strong interest in geospatial data storage. For a fuller picture of the spatial aspects of their latest product, Oracle 10g, GIM International interviewed Dr Jayant Sharma, technical director of Oracle Spatial Products, in New Delhi, India. Biography of Dr Sharma Dr Jayant Sharma is technical director, spatial products at Oracle's New England Development Center and has over a decade experience in databases and spatial information systems. He was responsible for building the spatial product team when he joined Oracle Corporation in 1996. He also represents Oracle at Open... (read more)

3D Geo-database Services

Interdisciplinary solutions for early hazard warning and disaster management require easy access to large sets of geo-referenced data. Therefore, three-dimensional (3D) geo-databases, hitherto hardly noticed by the public and decision makers, will probably have a central role to play, a situation comparable to the appearance of 3D city models 15 years ago. At that time, these models seemed to be too expensive to become widely used, but now it is clear that visualisation of 3D city models is only the first step on the way to further analysis for experts and decision makers in disaster management.   Obviously, the processing...
