We got some variable results with SD cards in some recent fieldwork – cameras not taking photos as regularly as possible, transfer rates not as advertised – and some research turned up even more disturbing news about SD cards and what to watch out for. SD cards are cheap because they are fundamentally made of …
We’re about to start a livestock and wildlife census in the Serengeti ecosystem, and using a point photo count method (APS). This is the first time we’ll have used APS for anything other than wildebeest, and we’re working on managing a different (and much larger) set of data. Post-flight processing includes geotagging the photos collected based on …

Once, the only serious way to do much GIS work on your Mac was to use ArcGIS (or MapInfo) in a Windows virtual machine … but not anymore. QGIS Quantum GIS can now really compete with ArcGIS in terms of functionality and map creation. I miss a few things – proportional symbols for one – …
Kickstarter certainly seems interesting; I’ve been browsing their site (and, in doing so, found two excellent little projects that seemed worthwhile and put some cash towards them) and taking some notes on what seems to succeed and what doesn’t. With all the interest in drones and wildlife survey, I was thinking that it might be …
Is Powerpoint evil? Tufte certainly thinks so, and it’s worth paying attention to genius. Edward Tufte Kills a Kitten infographic Is Powerpoint evil? Tufte certainly thinks so, and it’s worth paying attention to genius. Edward Tufte Kills a Kitten infographic
I often need to provide coordinates to light aircraft pilots – and most of them still use degree-minute-second notation (DMS) for charts and GPS. If we can’t upload flight plans and waypoints directly to the GPS I need to provide tables of DMS points – while QGIS can display in DMS in the canvas, it doesn’t …
Running QGIS on an android phone worked just fine – but running QGIS on an Android tablet is going to be a lot more useful, with a larger screen. I summarised the steps of installing QGIS on a Galaxy Advance (I9070) in a previous post, under Gingerbread (2.3.6); since then, there have been some issues …
This is an update to a previous post of the same name, but with more info on actual reinstallation.

The main problem …
