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.

Maldives Update

Posted by MapMakinMeyers on 28 August 2015 in English (English)

looking around the maldives, it has some pretty rough coastlines or islands missing altogether. I am assuming most of the coastline data was from the prototype global shoreline data from the NGA (which is junk). get out and map some islands people!!!

have a good weekend!

Nepal, OSM License, and the NGA

Posted by MapMakinMeyers on 29 April 2015 in English (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:

Also, the NGA has some data available: (ebola and nepal)

if you go to the main Nepal page they have several pdf atlases:

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.

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 ( 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!

NGA/ US Govt Data Questions, help, random rant, etc

Posted by MapMakinMeyers on 31 January 2014 in English (English)

So for the past several years I have been downloading the GNS Country files ( Some of the data is great. Most of the data is way off. All in all it is helpful. In the past OSM imported some of this data in countries that were lacking. This is good and bad for different reasons in different countries. So now comes the questions/ rant section of the post.

I recently reached out to them to ask several questions about the data, sources, accuracy, etc. I had to wait over a week to hear a response (after I sent a follow-up e-mail they started to respond). Now I am in the process of waiting again... I asked several questions and have suggested a few locations that are most likely duplicates (so they can clean the data). I am assuming I shouldn't hold my breath in expecting a response. Several years ago I reached out to them about a bunch of junk duplicates in the Dominican Republic - and basically they told me they were not going to fix them because their sources confirmed them (although traveling to the Dominican and having a GPS and geotagged pictures should be more accurate than some commercial company vectorizing paper maps...)... Anyway I was wondering what the OSM community's perspective is on asking governments for data. I know open data plays a huge role in updating OSM (whether it be in imports, confirming data, adding supplemental attributes, etc). In all honesty OSM is better than most commercial datasets, and in most cases it is better than government data. Some governments even have their official maps based on OSM data (which is very cool). But at the end of the day, it is governments that create boundaries, name places, and have this information. It is digital, it does exist, and people/ the public should deserve the right to see it, use it, etc. Trying to communicate this to governments is so difficult - its like hitting your head against a wall to get someone to listen, understand what you are talking about, get a response, and just get through to them. Several years ago I filed several FOIAs to the NGA and numerous governmental agencies about VMAP1. It took over eight months for me to get a NO; you and the public cannot access the data blanket response. So I am about to embark on a journey of asking for data. Filing FOIAs. Basically leaving no resource, contact, agency, etc any wiggle room for a no. I have a pretty good game plan as to how I am going to go about contacting them, following up, following up, and following up. At the end of this I expect many people to tell me no, the government cannot release the data to the public, etc. But I am going to keep asking, changing my question to be more specific, asking in a different way, asking about different data, etc. I will probably go nuts doing this, but it needs to be done. It is a bunch of BS that the general view of the US govt is to have open data ( but at the end of the day, governments have so much red tape that you cannot even get a e-mail response (more head banging against the wall)...

So now comes a question if I didn't state it in my rant!... Has anyone done this? Has the OSM community filed any FOIAs or petitions asking government agencies for data? Does anyone want to help, have suggestions, or any input?
