Last weekend, myself and the rest of the OpenCage team were in Karlsruhe in Germany for the second annual OpenStreetMap State of the Map Europe conference. It was probably one of the best run and most diverse OSM conferences I’ve been to.

For a start the key essential elements for a conference were there; there was plentiful coffee and the wifi was both fast and more importantly, it didn’t die horribly during the conference.

I’d submitted a talk called Geocoding – The Missing Link For OSM? and had been asked to actually give that talk. That was my reason for being at SOTM-EU. But we were also going to soft launch OpenCage Data’s latest offering, a geocoding API that’s powered by OSM and other Open Data and which is built using open source commodity components. That’s the reason Ed and Marc Tobias were also in Karlsruhe.

This week the GeoBusiness conference took place in London and as far as geo-themed conferences go it was a broad themed and mixed bag of an event. GIS was heavily represented as was the BIM element of this geo-discipline. The collection of raw data was a prevailing theme on the exhibition booths with drones aplenty and LIDAR cars out in the car park of the Business Design Centre. Thankfully the data and web driven part of the industry was also represented and I played my part by giving a talk.

One of the great things about the combination of maps, geo, location and London is that roughly once a month there’s some kind of meetup happening in the city on these themes. One of the longer running players in this space is the Geospatial Specialist Group of the British Computer Society which is being relaunched and reinvigorated as the Location Information SG. Earlier this week I gave a talk, but what to talk about?

In English, null means nothing, nil, empty or void. In computing, null is a special value for nothing, an empty value. In geography, null tends to be what you get when you’ve been unable to geocode a place or an address and haven’t checked the geocoder’s response. What you end up with is a pair of coordinates of 0 degrees longitude and 0 degrees latitude, a point somewhere in the middle of the Atlantic Ocean, south of Ghana and west of Gabon. It’s here that you’ll also find Null Island, if you look hard enough.

I like maps. Even if you’ve never read posts on this site, the name “Mostly Maps” should probably be a giveaway. What you may not know is that I don’t really like musicals. Now granted I’ve seen Rent and Spamalot, but that’s because Alison and I were in New York and the former was recommended by one of my best friends and for the latter I’m a massive Python fan. Maps and musicals aren’t something that go together. But that may be about to change.

It’s easy to get stuck in a mental rut, to think that everyone thinks and feels the same way you do about a subject. But sometimes you need to get away and visit another country and another culture to find out that maybe there’s more than one way of looking at a subject. For me that subject is, unsurprisingly, maps and the other country was India.
