Disruption in the Geospatial Age (pt1)

Posted by: Will Cadell 6 months, 2 weeks ago

How grand I am to throw around terms like 'the geospatial age' as if I’m some kind of luminary. It sounds wonderful that we might be in some kind of 'age', but really, what on Earth does that mean? Well, what I mean is we as a technology community we are closer to geospatial technology than we have ever been. Indeed, billions of us literally hold it in our hands much of our waking lives. As such, we are now seeing an enormous development in the expectation and exploitation of geography as a toolkit. Sometimes this is wonderful to witness and sometimes terrible, but nevertheless we see maps and coordinates everywhere powering everything from restaurant reviews to rocket ships. Yes, our age is overtly geospatial.

Scale in a time of web maps

Scale has taken on a completely new meaning for me.

The big 'thing' about GIS was that it was scale-less; you could zoom in as much as you wanted and the map changes accordingly, amazing!

Google Maps have been with us since February 2005, virtually a decade ago as I write this (expect a party on Feb 8th 2015). From their acquisitions of Where 2 Technologies and Keyhole, Google ignited a cartographic web revolution. Yes, of course there were maps on the internet pre-Google Maps, but Google brought the web map to the consumer, and has driven the expectation of location intelligence in web and mobile apps ever since.

Mapping Exif Files

Posted by: Will Cadell in technology open source tools google maps code 3 years, 5 months ago

This is a quick note on how to map images in a directory purely from their exif files. An exif file is one which contains the meta data of the image. If the image was taken by a phone of GPS enabled camera, then a location will also be contained within that file. To read that directory on the webserver we need to use a CGI script. For our purposes we will use python.
