Old Data – New Data: When To Collect Geospatial Data?

Does old geospatial data have value? Is new geodata better? Project needs change and the spatially related questions being asked may be different, requiring new data. When is the best time to collect spatial data and what are some of the considerations involved? Does one approach over another have particular advantages when comes to planning

Where Did All the Talk About Spatial Data Quality Go?

About three years ago spatial data quality was the topic of the day. Everyone seemed to be talking about it. It was important, and seemed to be gathering momentum for a thrust into the direction of improved spatial data quality factors, how to assess them and go on. Suddenly it seems as if that period

Should You Have a GIS Survey Done Before Buying a Business?

Land surveyors have long promoted the hiring of a land surveyor prior to purchasing property. It provides buyers with the assurance that what they are paying for is what they are getting. It supports the transaction legally. Geographic Information Systems are in many organizations today. They are used as strategic business tools that enable up-to-date

How Are Surveyors Impacted By Changing Geospatial Technology?

Innovations in technology development are altering the ability to capture, manage, model and represent surveying data today. The fact is, surveyors operate under different regulations, perspectives and domains globally. Moreover, there are differences between companies that offer surveying services with some following traditional domain approaches, while others venture across disciplines and successfully engage new multi-disciplinary

Are Surveyors, Designers, Educators and Other Geospatial Users on the Verge of a New 3D glass-free Era?

Three-dimensional viewing is advancing with the development of glass-free, 3D visualization. Mobile phones and televisions are now equipped with the technology and it won’t be long until we see 3D in mainstream geospatial applications.  This innovation will expand across many disciplines including surveying, GIS, CAD and visualisation applications. In doing so, the nature of how

How Are Geospatial Technologies Impacting the Agriculture Industry?

World population is poised to expand to 8.3 billion by 2030. An extra one billion tonnes of cereals will be needed by that time – in comparison to total 2011 world production of 2.3 billion tonnes. Water systems are currently under stress from numerous factors and urbanization is depleting the presence of the most productive

What Does It Mean to Be a GIS ‘Champion’?

Geographic information system (GIS) development and applications often include a ‘Champion’ – someone that drives the project forward. While we might visualise someone holding a gold plated badge over their head like Rocky did in the movie, the fact is, anyone can be a GIS Champion. Such individuals focus on the project, attempting to ensure smooth

How Do Geographic Information, Mapping and GIS Connect with News Media Today?

News Media  today are evolving to include more geographic related information into a continuous news stream that is globally live. The origins of stories and breaking news events are being plugged into both professional and consumer oriented tools and technologies. A digital conduit strings together rapidly innovating tools, historical information with current happenings, whose ingredients

How Do Satellite Images and Airborne Imagery Relate to Agriculture and Forestry?

Satellite and aerial imagery play a significant role in modern day agricultural production and forest related activities. Advances in image sensors help to identify and delineate landscape level food production not only in different ways, but more quickly and effectively than before – and at higher resolutions. Image processing software supports these sensors, providing greater

Are GIS for Airports More Closely Linked to 3D Digital City Models Than We Realise?

Geographic Information Systems (GIS) are increasingly being used for airport management. They integrate runway operations, advertising spaces, emergency services and provide valuable functions for construction and general airport infrastructure management – airports are small cities. The goal of these city-like places may connect more closely to urban planning and wider economic factors for major cities
