Punch Card GIS: The Canada Geographic Information System

By GIS, giscience

The Canada Geographic Information System (CGIS) was developed in the 1950s and 1960s to assist in regulatory procedures of land-use management and resource monitoring. At that time, Canada was beginning to realize problems associated with its seemingly endless boundaries, in combination with natural resource availability.

The government therefore decided to launch a national program to assist in management and inventory of its resources. The simple automated computer processes designed to store and process large amounts of data enabled Canada to begin a national land-use management program and become a foremost promoter of geographic information systems (GIS) (ref wikipedia).

The movie below is the second of a three part documentary on the system, it details the digitising process beghind the CGIS and provides an insight into how anywhere in the world can be located using ‘numbers’:

You can recreate the 1960’s experience by loading up ArcMap and making ‘beeping’ noises while punching small holes in a business card.

Take a look at the other parts via YouTube.

Augmented Reality in (outside) of Second Life

By Augmented Reality, Second Life

As we have pondered in various posts Augmented Reality is a quick win in terms of visualisation, it is realtivly easy to implement and has a high ‘wow’ factor. The concept is simple, a webcam is linked up via a toolkit that is able to identify printed tags, the system then superimposes and 3D model over the scene – thus augmenting reality.

Of course the printed tags dont have to be ‘physical’ they can be embedded into Virtual Worlds such as Second Life, creating a really unqiue concept of importing/moving and visualisation objects in a virtual environment.

Take a look at the video below from cristiancontini for a really interesting proof of concept:

OpenStreetMap: A Year of Edits Video

By Open Street Map


OSM 2008: A Year of Edits from ItoWorld on Vimeo.

The movie above detailing edits to the OpenStreetMap.org project during 2008 was produced using a custom written Open GL package running on a Linux workstation. OpenStreetMap is a wiki-style map of the world and this animation displays a white flash each time a way is entered or updated. Some edits are a result of a physical local survey by a contributor with a GPS unit and taking notes, other edits are done remotely using aerial photography or out-of-copyright maps, and some are bulk imports of official data.

OpenStreetMap started in 2004 and the rate of contributions is accelerating with four times as many people contributing to the project in 2008 compared to 2007. During the year, edits were made by some 20,000 individuals and there were bulk imports of data for many places, including the USA, India, Italy and Belarus which are clearly visible in the animation. (wiki.openstreetmap.org/wiki/Potential_Datasources)

This animation was produced by itoworld.com with financial support from ideasintransit.org;Various stills are available from flickr.com/groups/itomedia/pool/. The music is ‘Open Electro’ by Vincent Girès’ jamendo.com/en/artist/silence and can be downloaded from archive.org/details/silence-silence.
