zdravo,

I have decided to begin verifying claims the there are a set of ancient pyramid structures) just north of Sarajevo near the town of [Visoko] (osm.org/way/189725592#map=17/43.97682/18.17845&layers=D) and making a better map of the area. After vacationing last year and visiting the site myself I felt the directions to this tourist attraction was lacking. I also felt that the investigators needed help with their claims.

For those unfamiliar with Visoko’s #1 thing to do based on tripadvisor

They just released HIFLD Open Data: A National foundation-level geospatial data within the open public domain that can be useful to support community preparedness, resiliency, research, and more.

I was curious what HIFLD Open data looked like compared with OpenStreetMap.

I had a free lunch hour so…

I did a small case study in Pennsylvania

I took one of the 250+ layers (hospitals) that has a well defined attribute naming convention and compared it with OpenStreetMap version using Turf.js. I modifed the code in the Mapbox example

The HIFLD Open Dataset Filtered for only PA converted to geojson using geojson.io

Locations= 255

The OpenStreetMap Hospitals Filtered using the OverPass Turbo API

pois: 232

HILFD OPEN vs OSM Hospital Map

*Blue = HIFLD Open

*Red = OSM

You can see HIFLD looks more complete in the rural areas

My name is Jonathan Witcoski. I am running for 2015 OSM US Board.

I joined OpenStreetMap November 7,2014 as part of a HOT MissingMaps party hosted by the Red Cross at their headquarters in D.C. I have participated in many Missing Maps mapping parties since then. Along with participating with HOT I began mapping my hometown in Northeastern Pa. For the last year I have also dug deeper into the OpenStreetMap and and companies that use it (i.e mapbox, cartodb) API and tutorials. I have also attended the State of the Map 2015 in New York City and presented at HOT Summit 2015 in Washington D.C. I also learned about OpenStreetMap US, joined a few days ago! I would like to play a greater role in OpenStreetMap by being apart of the OSM US Board.

I can bring many of my professional experiences to the table for the OpenStreetMap community. From 2009-2014 I worked on a project known as Homeland Infrastructure Foundation – Level Data HIFLD. The project mimics OpenStreetMap at a inter-federal governmental level in that it focused on capturing federal, state, and local government geospatial information and then distributing it as base data for the federal, state, and local governments to use. This experience has taught me a lot of about data license agreements and the hassle it is to get agencies to change their policies on sharing.

As a board member I would help however possible including:

1.) Encouraging participation from colleges and universities. Training future professional geographers that there is more than just official data sources. Scholarships to conferences, encouraging professors to incorporate it into his curriculum, more meetups.

2.) Living near D.C. I am very close to many federal agencies and could help facilitate discussions with them about openstreetmap and participating.

I thought it would be fun to create a little test project to more familiarize myself with OpenStreetMap and Overpass Turbo

Note, this is a work in progress. Any tips will be useful

I read a few mentions on how some organizations have used OpenStreetMap to calculate population density. I figured I would give it a go.

1. Create a OpenStreetMap Map

First I created a simple map interface with needed tools and legends using Mapbox Tutorials. I then put up a sample code page on github. Population Count Test Page

2. Count the Number of Different Buildings in OpenStreetMap

The next step(s) would then be to extract the Houses and other buildings from the dataset. An example would be. Extract Houses with Overpass Turbo ( // query part for: “House” node["building"="house"]({{bbox}}); way["building"="house"]({{bbox}}); relation["building"="house"]({{bbox}}); );

Set OverPass Query to only count and put into a json file

Count of Elements

out count;

Hello community,

I joined your group six months and am having a great time. I got involved through attending the Missing Maps group helping to trace satellite imagery.

While vacationing in the Balkans last year I kept running into minefield hazards signs being put up and from my time helping build OSM I haven’t encountered that layer yet. In some parts of the world I can imagine that being a hidden but important part of the landscape.

Being as I am new to this community I figured I could ask what there is out there.

There are a few discussions out there on it. 1.[Road Barrier] (osm.wiki/Talk:Key:barrier#Mine_field) 2.[Hazard] (osm.wiki/Talk:Proposed_features/hazard)

As well as a few nodes and areas already tagged [tag 1] (osm.org/node/3023658093#map=13/45.2779/16.9406&layers=HN)
