Raster and Vector Data in GIS

When we come to depict any spatial data in GIS, from physical assets and locations to real-world events and trends, there are two differing systems to display data; Raster and Vector representations.  Both of these methods present data in their own format, with their own advantages and disadvantages.

Metes and Bounds

Spatial Vision recently completed a project for the Electoral Commission of Queensland preparing a series of maps for new electoral district boundaries.  As well as the maps, there was a legislative requirement that ‘metes and bounds’ boundary descriptions be prepared for the new boundaries for publication in the Queensland Government Gazette .

What makes a City Smart is People

There are many definitions of Smart Cities and examples of what they can achieve. However, it would appear that there is no cogent model or framework to define them let alone measure their success. That being said, Marc Jadoul from Alcatel Lucent has laid out four steps to build Smarter Cities in a recent presentation: 

1. Networked infrastructure
2. Big data and open data
3. Smart public services
4. Citizen applications

Not surprisingly, a network communications platform is the foundation for the plan. Jadoul was very complimentary on Australia’s investment in the National broadband Network (NBN) that will assist to establish high speed connectivity across the country.

The second step is about data and governance. Data comes in many forms and sources. Jadoul reckons that ‘big data’ is the oil of the 21st century. With already more things connected to the internet than people on our planet, the Internet of Things (IoT) is creating a wealth of (big) data to be tapped. Our smart phones and cars are already generating legions of dynamic data from multiple sensors. Combined with sensors tied to all sorts of assets such street lights, CCTV cameras, shipping containers and even connected coffee pots our cup runneth over.

Visual intelligence to inform voters

Federal and State elections bring into focus a broad range of issues, some or many of which are very important to us.   Ultimately, it is the balancing of these issues and judgements about the various visions, priorities and programs on offer that determines how we vote.

Many of the promises offered up by the different parties can be presented in map form.   Using interactive map tools, new spatial technology is allowing voters to engage and better understand issues than ever before.  Spatial Vision’s itsyourvote.com.au is a good example of such an approach.  This site shows how social and political issues that emerged in the lead up to last year’s Victorian State Election could be visualised in the form of interactive maps.

It all starts with an address

Call triple zero; you expect the ambulance to get there promptly. Move into a new house; you expect to be able to get connected to gas and electricity etc. Many vital life transactions depend on reliable geospatial data for property addresses. In Victoria, the custodian for provision of most address data is your local government.

Many local councils currently face challenges maintaining this and other geospatial data, often due to easily preventable organisational issues. A key flaw with many councils’ is the lack of appreciation of the importance of geospatial data among the organisation’s upper tiers.

Get Your GIS Strategy Going

Given up on strategic plans because no one pays them any attention?
Can’t get the decision makers to read them, let alone fund them?

Too often I see strategic plans that describe implementing lots of technology but fail to demonstrate successfully how they will benefit the organisation or customers.

Effective strategic plans lay out a vision and a common set of organisational goals (describing how to get there and measure progress along the way). If the plan is going to be successful, it needs to be accepted across an organisation: people need to understand what the plan will deliver and how it is to be achieved.

BIM, CAD and GIS – what’s in a name?

Report from the Association for Geographic Information (AGI) GeoCommunity '11 conference in Nottingham, UK

So you know what GIS (Geographic Information System) and CAD (Computer Aided Design) stand for, what about BIM? It was new to me. Building information modelling is defined as the process of generating and managing building data during its life cycle. The Building Information Models encompass building geometry and quantities and properties of building components. Pieces can carry attributes for selecting and ordering them automatically, providing cost estimates and well as material tracking and ordering (Wikipedia 2011).

Water Industry Survey

In 2002, Spatial Vision completed the first GIS Benchmark Survey of Water Authorities in Victoria. Spatial Vision has since followed this up with national surveys in 2006 and 2009. The purpose for the surveys is to enable each authority to benchmark their operational deployment of this technology against their industry counterparts.

Water authorities first started using GIS or spatial information technologies in the early 1980s. However, as evident by Google Earth, the technology has rapidly evolved in recent years and become far more accessible. By 2009, 100% of authorities surveyed operated web-based spatial systems available enterprise-wide, a huge shift from 40% in 2002.
