Time series analysis of albedo on Humboldt Glacier, Greenland

Following on from the previous post, the second glacier analysed was the Humboldt Glacier (HG) shown in Fig. 1; the largest in Greenland. This was used to provide method validation with Box et al (2012), which encompassed the whole of the Greenland Ice Sheet (GrIS), as well as a more detailed and localised analysis of individual glacier albedo behaviour. 323 more words

Routing in polygon layers? Yes we can!

A few weeks ago, the city of Vienna released a great dataset: the so-called “Fl├Ąchen-Mehrzweckkarte” (FMZK) is a polygon vector layer with an amazing level of detail which contains roads, buildings, sidewalk, parking lots and much more detail: 273 more words


Intrasite Spatial Analysis of a Late Upper Paleolithic French Site Using Geographic Information Systems by Dustin Keeler

This paper is an analysis of site structure as it applies to social and behavioral organization within Paleolithic hunter-gather camp sites. A complete understanding of site structure requires the examination of high-definition sites that are very well preserved in terms of their spatial integrity. 148 more words
