Today we are launching OSM Analytics, a platform for exploring and analyzing OpenStreetMap data. With the current database growing to almost 50 gigabytes, and thousands of features added every day, OSM is officially entering the big data league.

by Mhairi O'Hara, Tyler Radford As of the 22nd of April there have been over a million and a half changes made to OpenStreetMap in response to the 7.8 magnitude earthquake that struck Ecuador on the 16th of April. There have been 500+ aftershocks and the number of fatalities has also passed 500. Support is strong with more than 1,700 contributors volunteering their time to help map priority areas through the HOT Tasking Manager. HOT continues to remain activated at the “Moderate” event level as defined in the HOT Activation Protocol. The activation is being led by local and regional HOT volunteers with support from HOT’s global community and activators outside the region. There are 8 dedicated projects set up in the HOT Tasking Manager to coordinate those that wish to assist with mapping affected areas. To see the full list, please see the wiki page. There are also notes on how to contribute and get started with mapping.   Imagery

  Greetings HOT community, For a few years now we have been contemplating a new look, and more importantly - improved usability, of our website In 2015 our Technical Working Group recruited HOT Voting Member, Felix Delattre, to generally manage and facilitate website development on a volunteer basis. Since then, we have been able to better coordinate and work on things here and there to make improvement; including the much needed project pages, member profiles, and more.

Ambon, located in Maluku islands which also located inside the Molucca Sea Collision Zone. This condition put Maluku as one of disaster prone province. Indonesia Disaster Risk Index 2013, published by Indonesia Disaster Management Agency (BNPB), clasify all 11 districts/city in Maluku as high risk. A national and international tabletop exercise (TTX) in Ambon to improve mitigation and preparedness in the area is planned to be done in 2016. Before the TTX can be done, there are several activities that needs to be completed. One of the first activities needed to be done is data collection.

Ecuador: An earthquake of magnitude 7.8 hit the coastal region of Ecuador on April 16th. This major event was followed by several aftershocks. HOT is currently at "Moderate Event (Local Leadership)" status and is continuing to monitor the situation and await more guidance from colleagues in Ecuador. Japan: On April 14th and 15th, several earthquakes hit Kumamoto Japan. Our colleagues at Crisis Mappers Japan ( are taking the lead on mapping the affected areas in OpenStreetMap. Several members of Crisis Mappers Japan traveled to Kumamoto this weekend to assess data needs. HOT is monitoring the situation and will provide additional support as needed.

(Guest post by Mercedes Hoffay, Master of Public Administration Candidate - Columbia University). All policy students are obsessed with the effectiveness and feasibility of policies and programs that governments implement. So when we find a tool that allows significant efficiency gains in government planning, we are thrilled. That is how we felt when we embarked on our Graduate Capstone Project to evaluate the Humanitarian OpenStreetMap Team’s work in Tanzania and their role in Dar Ramani Huria.

Last week in Washington DC, HOT kicked off work to develop a prototype tool for OSM data analysis. With generous support from the Knight Foundation, HOT began the design phase and discussed ideas on how to make it easy for anyone to gain insights into OSM data.  Understanding the quality and quantity of geospatial data in OpenStreetMap is not an easy task, especially for those less familiar with the OSM project or with mapping technology in general. Today an increasing number of humanitarian organizations rely on OSM basemap data for coordinating disaster response operations. Journalists and communities also use OSM derived maps to tell stories about humanitarian crisis or to discuss local issues. It is crucial for those and many other users of OSM maps to understand the characteristics of such data to be able to use it efficiently and confidently. This often includes an assessment of data coverage, map statistics, change monitoring, and the identification of gaps and inconsistencies.

For the past 2 years, HOT in Indonesia is implementing a university program to build partnerships and collaborations with universities, disaster research centers, and local disaster management agencies.The purpose is for the universities to have the capacity to map exposure data in vulnerable areas and could support local disaster management agency in their area when needed. The big goal of this program is to have disaster prone areas in Indonesia to be well mapped.

We have three Ugandan mapping supervisors on the HOT mapping team in Uganda: Douglas Ssebaggala, Geoffrey Kateregga and Ketty Adoch. They've all been involved with OpenStreetMap and HOT for some time, and would like to share their story and mapping history. Today, we're speaking to Douglas.

Mozambique is a country of 25 million people on the east coast of Africa, often beset by natural disasters ranging from severe drought to devastating floods as well as civil wars and strife. Dar Ramani Huria and HOT have recently started mapping in Mozambique, to support critical public health work.Struggling with one of the highest child mortality rates in Africa, the Mozambique Ministry of Health has worked to reduce the death rate for children, which in some provinces means that as many as 10% of the children do not live to see their 5th birthday.Health Alliance International (HAI), a Center of the Department of Global Health at the University of Washington, has been working in solidarity with the government of Mozambique for over 25 years to improve access to and the effectiveness of the public-sector healthcare system.

Guest post by Kathryn Davis, Columbia University. January 14th, 10:30am. We arrive in Chang'ombe ward (an industrial area in Dar es Salaam) after weaving in and out of traffic in the project bajaj (rickshaw) through different neighborhoods. Johannes Peter, a seasoned mapper with the Dar Ramani Huria project, takes another look at his drone imagery printout of the area, and indicates that we’ve arrived at our starting point.Mappers like Johannes detail key drainage and water infrastructure that hasn't been digitized before, and that can be used for disaster risk reduction planning and flood resilience. Almost immediately, we see drainage on the right side of the wide dirt road, and mark it on the map...

A young woman anxiously practices a talk about youth in OSM that she is slated to give at the HOT Summit the following day. Impostor’s syndrome has convinced her that it be would better for her not to give the talk at all; she’s relatively new to HOT and has few technical skills. She’ll be easily exposed as a fraud, and the audience members surely have better uses of their time than listening to her (spoiler alert: that was me at the first HOT Summit).

Guest post by Pratik Yadav, data analyst at Mapbox. The HOT Tasking Manager (TM) has been the critical tool for rapid and massive coordination for disaster response and preparedness mapping. Since the first task in September 2011, there have been a total of 1168 tasks published in the Tasking Manager. This map shows the footprint of all HOT tasks up to January 5, 2016, with a total coverage of about 7,449,759 sq kms.   You'll notice a variety of shapes of HOT TM jobs. Some are hand drawn around small focus areas, and others are large, representing the area of a data import, and a few are thin corridors along roadways.

We made great progress on a crowd-sourced public transportation map for Managua! Over seventy generous donours supported us, through our crowd-funding initiative, to raise $6,212 dollars and with this they enabled us to print the city's bus map 40,000 times. Yesterday, members of the OpenStreetMap Nicaragua cummunity handed over the collaboratively created and printed public transportation maps to the people. Managua became Central America's first capital with a complete transportation map. And only the community made this possible:

When I was first told about mapping, I thought it was something to do sitting indoors on your laptop. Well, it’s also a bit like that, but little did I know the adventure that awaited me. I quickly got acquainted with the whole mapping process after the training we received on the first two days (ed: 11 and 12 January). Earlier I had met Douglas Ssebaggala who had showed us how to use OpenMapKit and JOSM. I just couldn’t wait to start my journey in the world. After the training, I felt I was ready.

Smartphone is everywhere. In Indonesia alone, it is estimated in 2015 that there are around 55 million of smartphone users, the third highest number in Asia Pacific. To tap into this huge potential, HOT Indonesia with the support from Australia-Indonesia Facilities for Disaster Reduction have started developed Android app for mobile data collection back in 2014. It was started by developing the concept notes for the application based on HOT Indonesia experience in delivering training throughout Indonesia.

As we enter our second week in Mbale, we've started surveying the surrounding districts of Sironko, Manafwu and Baduda today (Monday, January 18th). These are spectacular areas to be surveying, being around Mount Elgon National Park and Sipi Falls. Last week, we mapped most of Mbale district while focusing on education and training, slowly increasing the scope and geographical areas assigned to teams for mapping tasks.
