Mapping the Earth's Changes Over Time

Mapping the Earth's Changes Over Time

Without time there is no change. Over longer periods of time we may expect more changes, but very significant changes can arise in short durations. Heavy rainfall brings floods, an earthquake can cause major damages in a few moments and hail can wipe out a crop in just a few intense minutes. But other changes may take longer periods of time. Changes in the course of rivers, urbanisation and changing population demographics are measured and monitored over longer periods.

Small Satellite Sector Set to Expand

Small earth orbiting satellites are gaining in popularity for their low costs of production, and ease of deployment. This satellite class is known as 'nano satellites,' and according to a recent market research report, the sector is expected to grow by 40 percent over the next five years, with more than 400 such satellites in lower earth orbit by 2014.

GIS Excels at the Assessment of Risk

The disruption and devastation of natural disasters would appear to be on the rise right now, particularly in Asia where flooding has impacted a large portion of this region. Over the years, experts have gathered knowledge of earth systems interactions and have created models to help predict and mitigate the risks from such disasters. Without GIS, our world would be a much more dangerous and disrupted place, but there is a good deal more insight to be drawn from the analysis of such risks.

NZ Topomaps Improving Access to NZ Topo Series

After the closure of NZTopoOnline, I saw a need to provide fast and easy access to NZ Topographic maps. Now forgive me for not using Open Street Map but I've just put together http://www.nztopomaps.com for easy access to the excellent resource that is the NZTopo maps. The idea came into my head when my grandfather, who is a very keen tramper and associated with Pioneer Trampers Club in Christchurch, asked me about access to "maps". I simply expected to do a Google search and find several mapping websites serving topo maps but there were none.
