Sorry for the quiet – had a lot going. So much so – let me start off here: Greetings from the US Virgin Islands.
There’s a lot to discuss and let me start off with Field Work. Yesterday I found myself and my handy coworker Zac roaming Charlotte Amalie. I also am in the possession of a new phone. A Google Nexus 4. We were trying a couple of things. One of which turned into Geotagging pics. You can with (I assume) every android phone (and Iphone) embed your lattitude and longitude into a pic. So that’s what I did. I ended up shooting about 20 pics and a few scenic tourist shots (above). I came back and the plan was to rip them into a shapefile. I think I even uttered that standard phrase of GIS Professionals everywhere “Well – I’ll just write a script to do this.”. Well – I’ve got work to do and script writing is for fun – so here is what I did.
- Open QGIS
- Download the Photo2shape plugin
- Download the pics from the phone to a directory
- Run Photo2shape
At the end I had a shapefile with the photo path and photo filename. What was nice I ended up with (red dots).
The Orange line is a different story. Every photo has a recorded location and the reported accuracy of the phone is 9 feet. I’ve noticed that with this phone GPS Status bottoms out there. So I’m guessing this is a software lock or something – because the points when matched to NAIP/Google are pretty close to what was expected. I know – I’m mixing all sorts of accuracies but that’s what I have to check it against. Three meters in general isn’t great – but for what we’re doing it’s pretty good.
Next up – Hyperlinking on QGIS……..
