FOSS4G 2014

noreply@blogger.com (Graeme Herbert) — Thu, 25 Sep 2014 21:14:00 +0000

This year was the third time I have attended FOSS4G, the international conference for open source GIS and mapping software. The first one I attended, in Denver in 2011, was my chance to find out what was going on in open source geospatial development. Despite many years of working in the GIS field, almost everything I saw and heard about in Denver was new to me, an indication of how it's possible to work in a specialised area and yet miss so much of what is happening around you.

The Street View time machine

I remember being very impressed when Google launched their Street View application in Spain as an addition feature to Google Maps. I even forgave them for not including my street at first, it seemed like a great idea. Although after the initial interest faded I can't say that I have been back using it very much. However, the other day I thought it might be a useful tool to check some data that I'd collected in Madrid where I wasn't absolutely sure about the location. When it came to looking at the area around Madrid's Puerta del Sol I soon realized that I had a problem.

Crowdmap - managing the map

noreply@blogger.com (Graeme Herbert) — Tue, 26 Jun 2012 10:45:00 +0000

In my previous post I described how to do the basic configuration of a crowdmap. The next step is to manage the way in which data will be presented on the map. Information on a crowdmap can come from a variety of sources. It is possible for visitors to the map to submit reports either directly through the map page or via other means such as Twitter or SMS. In addition, those who are managing the map can submit their own reports as administrators and can add news feeds that contain useful information.

Crowdmap - getting started

This is my first post in my series on how to use the Crowdmap site to host your own Ushahidi map. Here I deal with the most basic account creation and configuration details. Future posts will describe an example implementation of a crowdmap.

Ushahidi

noreply@blogger.com (Graeme Herbert) — Sat, 05 May 2012 14:10:00 +0000

One of the most interesting mapping tools that I have seen in the last couple of years is that developed by the non-profit company Ushahidi. The name means "testimony" in Swahili, and the origin of Ushahidi comes from the website they developed to help monitor reports of violence in the aftermath of the Kenyan elections in 2008. The core idea was that anyone could submit a report to the site via internet or a mobile phone and this would then be mapped, together with some assessment of its reliability.

VI Jornadas de SIG Libre

Last week I was in Girona attending the sixth edition of the Jornadas de SIG Libre. This is an annual event run by SIGTE, an organisation belonging to the University of Girona that is dedicated to geospatial research, training and knowledge transfer. I first came across SIGTE last year when I attended a summer school they run on open GIS software.

Apple's maps

noreply@blogger.com (Graeme Herbert) — Thu, 15 Mar 2012 09:58:00 +0000

The discovery last week that Apple seems to have used some tiles from Open Street Map (OSM) in its new iOS version of the iPhoto application has provoked speculation about yet another company making the switch to OSM. However, it seems that the data used is from some time ago, and even contained errors which have since been corrected in OSM. One great advantage of community sourced mapping is that errors get detected and corrected. The data has also been used with no attribution of its source, a condition of using OSM data.

Have Google Maps taken the wrong road?

noreply@blogger.com (Graeme Herbert) — Fri, 02 Mar 2012 10:54:00 +0000

It started with one or two isolated reports of companies abandoning the use of Google Maps for their websites and switching to Open Street Map (OSM) as their map server. One of the main reasons behind such a move has been Google's decision to change their charging policy for use of their maps. This seems to have forced some smaller companies into a position where they effectively had little choice but to look for a cheaper option.

State of the map 2011

noreply@blogger.com (Graeme Herbert) — Fri, 23 Sep 2011 13:03:00 +0000

This blog has been shamefully neglected for the whole summer, although I have been busy with some very interesting GIS related activities. I've just got back this week from a trip to Denver, where I have been attending two conferences; State of the Map 2011 (SOTM) and FOSS4G. I'll dedicate a post to each event, so let's start with SOTM, which is the annual meeting for people from around the world who contribute to, or who are interested in, Open Street Map (OSM).

Votos y cifras

noreply@blogger.com (Graeme Herbert) — Tue, 10 May 2011 14:44:00 +0000

Electioneering has started in Spain for municipal and regional elections which are to be held on May 22nd. To coincide with the campaign, Esri's Spanish office has put together an interesting map called Votos y Cifras (votes and figures) which combines different sources of data to map voting patterns by region against socio-economic data for each area.

Just because you're paranoid doesn't mean your iPhone is not following you

noreply@blogger.com (Graeme Herbert) — Tue, 03 May 2011 17:54:00 +0000

One of my initial ideas for a post to inaugurate this blog was going to be something about how the use of smartphones equipped with GPS means that many users of these devices freely share important data about their movements. Then came the revelations concerning the iPhone apparently storing data about where the user had been in a file held on the phone itself.
