Multi-scale analysis of surface roughness
Grohmann, C.H., Smith, M.J. and Riccomini, C. (in press)
IEEE Transactions on Geoscience and Remote Sensing
Surface roughness is an important geomorphological variable which has been used in the earth and planetary sciences to infer material properties, current/past processes and the time elapsed since formation....

A really nice PR blog entry over at SSTL on the decommissioning of Alsat-1, SSTLs first DMC satellite. Its a really nice example of a fit-for-purpose satellite, new low-cost technology and meeting the environmental needs of developing nations. Well worth a read.

AeroPress Coffee Maker
Came across the AeroPress coffee maker recently (thanks bro). Looks a very interesting take on coffee making by using a mix of a filter and plunger. However the plunger is an air plunger to create even pressure as the brewed coffee passes through the filter paper. Supposedly to create a smooth filtered taste, but with greater flavour. And, to boot, its portable.

Creating earlier versions of geodatabases
I'm amazed it's taken this long, but ESRI has now produced geoprocessing tools for creating earlier versions of geodatabases. I did a roundup blog on this 2 and a half years ago.....

University places... a slow news week?
OK, perhaps that's a little uncharitable, but there have been a few heckles raised at poor A-level students who don't get university places....

WMS Benchmarking 2010
OSGeo have announced the WMS benchmarking for 2010 which has seen a long list of products taking part. Last year it was MapServer and GeoServer, with ESRI having to pull out due to time commitments. This year its MapServer, GeoServer, CadCorp GeognoSIS, Constellation SDI, ERDAS Apollo, Mapnik, Oracle MapViewer and QGIS mapserver. Great to see such an extensive line-up.

I've been playing around with postcodes a little more recently, particularly since the OS released CodePoint under the open licensing model....

Terrestrial Laser Scanning for Mainstream Land Surveying
Good catch over at LiDAR News on an article by Mike Pinkerton, a surveyor in New Zealand reviewing the change that laser scanning is having on the industry. Worth a read.

GIM have a nice roundup of current terrestrial laser scanners which is well worth a look at. Select from the (limited!) list and see how comparable they are.

New CEO for Intermap
Interesting article over at All Points on the CEO of Intermap stepping down. The author has declared an interest in being a shareholder, but takes a fairly hard line on the state of Intermap who's share price is currently pretty low and potentially ripe for takeover. They have put alot of momentum behind NextMap and the collection of data for the USA and Europe. Is this the right direction to take? Time will tell, although it has seen hugely successful take up in the UK and perhaps this was part of the reason for expanding collection over much larger areas.

Google to use UAVs?
Blogoscoped and PCPro are reporting a recent interview from Microdrones CEO where he noted Google having recently purchased one of their UAVs. OK, so lets be clear, these aren't the same as the Global Hawk. They are small, programmable, multi-propeller drones that are ideally suited to collected imagery over relatively small areas. Their "top of the range" kit has a cruising speed of 15 m/s, flying time of 70mins and payload of ~1kg. So Big Brother it ain't, but it certainly is a useful addition for the collection of close range imagery.

Note the recent announcement that the full v1.0 release of PySAL (Python Spatial Analysis Library) has been finalised. Slashgeo has a good introductory paragraph, but note that this work has come out of two Python based geoprocessing projects that wanted to write a core Python library to avoid duplication of effort. It is not a front-end, but provides core spatial functions.
