Google making inroads with Enterprise GIS

It looks that Google is finally making some progress in Australia with selling its GIS enterprise solutions to government clients. The first, and for quite some time the only public sector user of Google technology was NT government but just in the last few months three other State governments succumbed to Google’s charms. In particular, Western Australian Land Information System (WALIS) is upgrading its GIS capabilities with Google Maps Engine platform and has already started serving some data in OGC compliant web service standards.

Earlier this month the NSW Land & Property Information (LPI) released NSW Globe, which allows displaying a range of State data in Google Earth, and in the last few days Queensland’s Department of Natural Resources and Mines released its version as Queensland Globe - with almost identical list of datasets.

It is good that more and more data is made accessible for preview in a public domain. Let’s hope that these initiatives are only a beginning and will lead to more investment into a proper infrastructure to serve the data to third party applications.

Displaying data on a map is so passé. It was a thrilling functionality a decade ago but these days, in order to make a real impact, the data has to be put in context of tasks that community and business undertake on regular basis. Which is anything from looking up bus timetable to researching optimal delivery routes, from searching properties for purchase to collecting business intelligence for marketing purposes, etc. 

Google has already recognised that tools it offers cannot deliver all those solutions so the company is focusing its efforts on enabling linking of data served from Google infrastructure to open source tools like QGIS - to enable users performing more specialised spatial tasks.

Government agencies should ideally follow a similar strategy. The best return on all that data in State and federal vaults will be if application developers are allowed unencumbered access to it. Whether it is Google or ESRI or other technology facilitating the access is not that critical as long as there is a long term commitment to maintain it.

New approach to satellite imagery analysis

Geoscience Australia has just released a short 3 min. video presenting a concept of “data cube” for storing and analysing Earth observation imagery acquired by satellites. This proof of concept application has been built to work with Landsat data and was already used in an operational capacity on several data analysis projects. This is the future of analysis of big volumes of temporal, remotely sensed data.

The concept can be extended to work with any data that can be referenced to a grid structure (in fact, to any spatial data that comprise of a collection of points in space). This is not the first attempt to work with cubed spatial data but certainly the first that I know of that is capable of processing terabytes of spatial imagery into a variety of derived information for immediate, practical use.

Beans, Lentils, and the Paleo Diet

As we continue to explore the foods our ancestors relied on during our evolutionary history, and what foods work best for us today, we come to legumes such as beans and lentils.  These are controversial foods within the Paleolithic diet community, while the broader nutrition community tends to view legumes as healthy.

Beans and lentils have a lot going for them.  They're one of the few foods that are simultaneously rich in protein and fiber, making them highly satiating and potentially good for the critters in our colon.  They're also relatively nutritious, delivering a hefty dose of vitamins and minerals.  The minerals are partially bound by the anti-nutrient phytic acid, but simply soaking and cooking beans and lentils typically degrades 30-70 percent of it, making the minerals more available for absorption (Food Phytates. Reddy and Sathe. 2002).  Omitting the soaking step greatly reduces the degradation of phytic acid (Food Phytates. Reddy and Sathe. 2002).

The only tangible downside to beans I can think of, from a nutritional standpoint, is that some people have a hard time with the large quantity of fermentable fiber they provide, particularly people who are sensitive to FODMAPs.  Thorough soaking prior to cooking can greatly increase the digestibility of the "musical fruit" by activating the sprouting program and leaching out tannins and indigestible saccharides.  I soak all beans and lentils for 12-24 hours.

The canonical Paleolithic diet approach excludes legumes because they were supposedly not part of our ancestral dietary pattern.  I'm going to argue here that there is good evidence of widespread legume consumption by hunter-gatherers and archaic humans, and that beans and lentils are therefore an "ancestral" food that falls within the Paleo diet rubric.  Many species of edible legumes are common around the globe, including in Africa, and the high calorie and protein content of legume seeds would have made them prime targets for exploitation by ancestral humans after the development of cooking.  Below, I've compiled a few examples of legume consumption by hunter-gatherers and extinct archaic humans.  I didn't have to look very hard to find these, and there are probably many other examples available.  If you know of any, please share them in the comments.

To be clear, I would eat beans and lentils even if they weren't part of ancestral hunter-gatherer diets, because they're inexpensive, nutritious, I like the taste, and they were safely consumed by many traditional agricultural populations probably including my own ancestors.
