More than a week ago I went to Colorado. The purpose of this trip wasn’t hiking (okay, I went hiking as well) but to attend the State of the Map US conference held at the University of Colorado Boulder. My talk was about how we’re trying to build a geospatial community in South Florida and I presented some results of our OSM building import. Recordings came online recently so here’s a video of my talk. Enjoy.
P.S. Hiking was also great. You’ve got to visit Colorado during fall! It’s amazing.
Oops, I forgot to share my “new” videos I made this June. Better later then never, I guess. Anyways, it’s part of my research that aims to understand how regular people on the Internet use different mapping platforms. Well, not just mapping platforms but basically any platforms that you can think of including Instagram, Foursquare, Twitter, Facebook an many more. We know that many of you use multiple services during your daily routines. Previous research focused on each of these data sources separately so we have a lot of knowledge on them (not playing the Big Brother here, I’m talking about an aggregated level). However, we do not yet know how the same individual uses these services simultaneously. Do activity spaces overlap? Is there a single main service or do people use different services with the same intensity? Does the introduction of a new service affect previous usage patterns? Can the user base from a platform drained by another? How do these processes work in time and space? Well, and I have many more questions. Probably way more questions than I can realistically answer, especially when don’t just talk about simple social media photos but really high quality mapping activities (as in editing OpenStreetMap and taking Mapillary street level photos specifically for mapping).
In case you haven’t made your summer vacation plans yet, I happen to be a guest lecturer for this intensive summer workshop/course. It’s mainly designed for wildlife ecologists so you might wonder what I’ll be doing there. Well, wherever spatial data is involved, I’m there!
While I surely won’t be the person providing ecological context, hopefully my participation will provide some different insights to the world of geographic data handling with spatial databases. I’ll try my best and come up with an interesting lecture about the possibilities of PostGIS in spatial data handling. You know, all the cool stuff. Buckle up, it will be an interesting course that is extremely useful for ecologists. Hoping to see you there!
A year ago, high quality aerial imagery with a 10cm ground resolution was made available to the OSM community in Szeged, Hungary. It’s a very good example of not just sitting on the data but trying to make use of it. In theory, OpenStreetMap community can absolutely benefit from having a data source like this as there are way more details to be derived from such high resolution imagery. Also, the positional accuracy of the orthophoto is worth mentioning. You know, this is the kind of aerial photograph that you can make measurements on, like if it was a true map. It’s important because you can skip playing with different offsets and dragging your base map around to make it appear in its “true” position before you can actually start mapping. So, truth’s been told. It’s cool, but what the heck is with it?
Well, It’s been a year or so. I can talk about the benefits for days but it doesn’t really matter if no one is acting accordingly, right? There are things that “should” work in theory but when it comes to online communities… well, that’ a whole different story. Anyway, let’s lurk around and see what awesome mappers of OSM think about all this (oh, did I just say awesome people of OSM? Is it a spoiler? Oh well, I guess you have to click on the link below and read more to figure it out.)
In my spare time, I teamed up with my old colleagues, the lovely faculty members at the University of Szeged, Department of Physical Geography and Geoinformatics to ask them for data donation. I couldn’t be happier to announce that after months of procrastination, some other delays and some more months of procrastination on my side, finally I am able to release a high resolution aerial imagery to the OpenStreetMap community for the solely purpose of mapping.
