Geospatial Data Distribution Partnership

Groupe Alta and Integrated Mapping Technologies have started a strategic alliance to integrate Web diffusion solutions and recurrent aerial acquisition programs to streamline distribution of high-precision geospatial data in British Columbia, Canada. The companies directly address the growing demand in the industry for up-to-date and high-precision geospatial data at lower costs through the introduction of the Lower Mainland Acquisition Program (LMAP) and geospatial Web platform, MyGeoWorld.com.     The LMAP program is to cover approximately 3000 km2 in the Greater Vancouver Metropolitan area and is based on a recurrent acquisition schedule to provide aerial imagery on a yearly basis and...

Geospatial Data Supply Contracts

Ordnance Survey has awarded a new four-year Framework Agreement for the Supply and Maintenance of Geospatial Data, which replaces previous data collection contracts. The Framework Agreement will run from April 2011 to March 2015 and sees Ordnance Survey developing its external supplier base for the supply and maintenance of topography, imagery and height data and services, which are used to maintain the currency, accuracy and information content of its core databases.   The framework agreement is divided into three lots and has been awarded in three lots.   Lot 1 includes Remotely Sensed Data Acquisition and contracts are awarded to...

Uniting Aviation with Data

Airborne Technologies
The Austrian company Airborne Technologies is specialised in two business fields: sensor integration/aircraft modification, and data acquisition/data processing. With its own fleet of multi-mission aircraft and data processing systems, Airborne Technologies unites the competences of aviation, data capturing and data processing all under one roof. Airborne Technologies (ABT) is a private limited company based at the Wiener Neustadt Airport near Vienna, Austria. The underlying business idea that led to the company being established was based upon two findings. The first of these was the shift of remote sensing technology from simple photogrammetric film cameras to a wide range of advanced... (read more)

Future-proof Data Storage

File and Database Storage Methods for Huge Point Clouds
Point cloud datasets have proven to be useful for many applications, ranging from engineering design to asset management. While point clouds are becoming denser and more accurate, new software is allowing an ever-broader user group for these datasets. However, due to their size and dependence on specialised tools, data management of point clouds is still complicated. A major consideration for data managers is the choice of point cloud storage format, as several different formats are available. Point cloud data can be collected in numerous ways, with laser scanning being the most common method. In terms of data management, it is... (read more)

Essential Data for Planners

Property Tax Returns and Ration Cards
Planners should focus on “essential?rather than a host of “desirable?or other data. That was the main thrust of a message published in GIM International, Vol. 20, No. 1. The same authors have now completed a study to further underpin their premise. Property Tax Return forms, together with Ration Cards, can provide about 75% of all “essential?data needed by planners. Minor additions might augment this to about 90%, thereby cutting acquisition costs and data redundancy.<P> Planners going about their daily business of planning, monitoring, management, implementation, and so on, presently collect data from primary surveys and secondary data from various sources....

Focus on Essential Data

Improving Plan-making by Selective Collection of Geo-information
How much of the data collected by planners is actually used in a plan-making exercise? "Very little," a planner will discreetly reply. Only 60% of data actually become input for plan making. Why then do planners collect so much data? Habit! Bound by traditions! And this whilst huge amounts of time and other resources are spent on collecting and analysing the same data, which in turn delays the start of the planning process, sometimes by several years. Differentiation, says this author, between essential and desirable data should provide the answer to this waste of resources. Planners everywhere collect a huge... (read more)

Spatial Data Clearinghouses

Information plays a key role in support of virtually any activity, in whatever nook or cranny of today’s society. About 80% of all public-sector information have geo-spatial component, referenced either by address or coordinates. In the long ago past a large diversity of governmental departments was created, primarily for reasons of administrative efficiency. Many of these collected and used geo-data and many are still in existence today. So in many countries, a great deal of geo-data is scattered across public agencies. And whilst they may have been effective in the past, these resulting islands of information do not well match... (read more)

Data Management Services

Solutions from Airbus Defence and Space
Easy access to repositories of space-borne imagery and other geospatial data is becoming increasingly important now that sensors are able to produce petabytes of data in the blink of an eye. The value of imagery to customers relies not only on its quality, but also on the ability to provide easy access to, and management and analysis of, the resulting geodata. Here, the author presents the geodata management services developed by the Geo-Intelligence programme line of Airbus Defence and Space and its strategic partners to serve the diverse needs of a broad spectrum of users. (By Jessi Dick, Airbus Defence... (read more)

Spatial Data Quality Degradation

Real-life Examples from Jordan
The competitiveness of an organisation is negatively affected by poor data quality, as introduced through the multitude of transformations and transfers carried out on original data. One risk involves uncontrolled exchange of data between organisations and departments within them. The author uses real-life examples from Jordan to demonstrate the impact of resolution, vector-to-raster conversion, scale, generalisation, classification of remotely sensed images and file exchange upon data quality. Data acquisition is the most important step in any GIS and Geomatics project. All results are influenced by the quality of the original data and subsequent steps involving transformation, transfer and exchange. Principal... (read more)
