I hope this isnt a dumb question - but why isn’t Minneapolis > St. Paul? I am assuming it is because it is a capital, but I think every other map I have ever seen always has Minneapolis slightly bigger font for the label. Happy Monday

GPS Tracks from Costa Rica Trip March 2016

I created this data with a Garmin 64st.

while driving I used a 1 second interval

while hiking I tried to change it to 3-5 seconds (if I remembered). The ferry from Paquera to Puntarenas I believe i did every 8-10 seconds.

I also saved my tracks with a Olympus Stylus TG-2. This data is pretty rough though (but there is one line when we went white water rafting that shows the river that I did not bring my GPS on).

I release this data to the public domain – you may use for any purpose.

Nepal, OSM License, and the NGA

Posted by MapMakinMeyers on 29 April 2015 in English.

unfortunately, tragedy brings about open data and huge osm efforts in remote locations that lack any data. Recently after the earthquake in Nepal, imagery, vector data, and tons of information are appearing on the internet every hour. very good sources are listed here: https://sites.google.com/site/nepalearthquakesatellite/

Also, the NGA has some data available: (ebola and nepal) https://nga.maps.arcgis.com/home/

if you go to the main Nepal page they have several pdf atlases: http://nga.maps.arcgis.com/apps/MapJournal/index.html?appid=bbbb3a2d7d8d42969f6ddeeb5d8c0e73

the red icons are for the pdfs that use OSM data.

Did anyone see the Sochi maps they leaked after the olympics started? same source: OSM. http://www.lib.utexas.edu/maps/commonwealth/sochi_2014_winter_olympics_reference_graphic-2014.pdf http://www.lib.utexas.edu/maps/commonwealth/sochi_2014_winter_olympics_talking_map-2014.pdf

the question i have is can governments use OSM data, then make it classified? Once you take the data and build upon it, don’t you have to share it back (https://www.openstreetmap.org/copyright)? you can file FOIAs until your blue in the face and they would never confirm/ deny OSM exists… but shouldn’t they follow license agreements put in place? I have reached out to them with regard to their open data for Ebola months ago. They do not respond to my e-mails. More of a rant I guess then a question. Cheers!
