Tile-based Data Storage and Visualization

Efficiently Serving Geospatial Data Using Vector Tiles and PostGIS

Tiles are not only pivotal for visualizing map data in browsers, but they can also revolutionize the way we store geospatial data. This article explores the use of a ’tile-based GIS’ for storing data like population distribution, utilizing PostGIS to efficiently export this data into vector tiles (MVT) for web-based dissemination.

The use of Free and Open Source Software in the OpenStreetMap Foundation

Report on a small study conducted

The Free and Open Source Software (FOSS) Policy Special Committee of the OpenStreetMap Foundation has been asked by the Board of Directors to assess the degree to which Free and/or Open Source Software or Services are being used within the OpenStreetMap Foundation (OSMF), the board itself, the different working groups, and committees. This analysis focuses on collaborative services to be used over the Internet. The FOSS Policy Special Committee was explicitly excluding the software used by the community at large, local chapters, or systems running on personal computers.

Candidate statement for the board of the Humanitarian OpenStreetMap Team

Elections 2020

The Humanitarian OpenStreetMap Team (HOT) is opening board elections, and I am delighted to be invited by Miriam Gonzales a.k.a. Mapanauta, Nathalie Sidibe (both current board members) and Enock Seth Nyamador to run for it. I am a long-time member of HOT, which I joined in 2013 when I was conducting mapping projects during my residency in Nicaragua.

Building your City’s Mobile and Web-based Journey Planner

Three directions to choose from

Many cities in the world need digital public transportation solutions: a World Bank study estimated for the year 2015 that 35% of the world’s largest cities and 92% of the largest cities in low and middle-income countries, do not have complete transit maps for planning or passenger information. This is currently undergoing a rapid change with new technologies. A lot of cities have started planning or implementing digital systems around public transportation data and services. One of the primary uses of technology in public transportation is to provide a passenger information system, or transit navigator or journey planning apps. This article gives a quick overview of the options cities have to successfully create one. Without reinventing the wheel – which would be a bad idea anyway – cities have three general directions they can choose from.

Now it is the time: Transit maps for everybody!

The simplest Open Source passenger information system

OpenStreetMap’s mobile application OsmAnd included recently time-less offline routing for public transportation in their Android version. This closes the gap of crowd-sourced mapping of public transport lines and stops to be provided directly as a useful digital tool that people can use - a minimal viable product made by and for a worldwide community of practice! Now, every single bus line, which has been put on OpenStreetMap becomes directly useful for everybody who just installs the OsmAnd application. This is a huge opportunity especially for the many cities in the world with a public transportation system, but without a map of it.

Mobile applications for Nicaragua's public transport

How OpenStreetMap data was made available to people's smartphones

After the Nicaraguan OpenStreetMap community crowd-sourced with over 250 interested citizens the data of their capital’s public transportation system in OpenStreetMap, a schematic paper map was created from this data. In a next step the community wanted to offer state-of-the-art routing applications to the visitors and inhabitants of Managua. For this, the data from OpenStreetMap was combined with also crowd-sourced schedule information by the Sofware tool osm2gtfs. The result is the common format for public transport data - GTFS -, which was then possible to include into existing applications, where the data can be used now…

osm2gtfs, extendable for any city

Convert data from OpenStreetMap into GTFS

osm2gtfs is a community based initiative for the development of a versatil tool to convert data from OpenStreetMap about public transport, combine it with external schedule information in order to create a General Transit Feed (GTFS). The Software has been programmed by community members of Brasil, Nicaragua, Costa Rica and France. Now osm2gtfs can be used without any programming skills, whenever using our defined input format. And, of course, with programming skills it is always flexibly extendedable to support any other city’s particularities and sources for schedules.

Digital Maps that make a change

Article about OpenStreetMap in the print magazine of the Austrian Scientific Exchange Service (OeAD News)

For the two students Taalaikul (15), Ulsana (16) and their teacher Kaiyrgul from the remote village of Jani-Talap, which lies on the edge of the roof of the world - on the Himalayas in the Tien Shan Mountains in Kyrgyzstan - water is the central theme. In the spring, the area is regularly flooded during the snowmelt, but after a few weeks, the wide river bed, which runs past the edge of the village, dries out for the rest of the year. The environment of the village appears dry and barren in summer, snowy in winter.

The true geographers are in the buses

Passengers created the public transportation map of Managua

When there is no map for the 1670 kilometers of metropolitan Managua’s public 45 bus lines network, there is only one thing you and anybody can do: Ask the people in the buses how to get from one point to another. The passengers of this complex - and naturally grown network within the capital - know most about it. And two years ago, a group of inhabitants of Managua by own initiative decided to take the feat and create the first bus network map in whole Central America.

A logo for OpenStreetMap Nicaragua

Wide collaboration to find a common identity for a community

In preparation of new great things we are developing in the Nicaraguan OpenStreetMap community - and which I obviously don’t want to spoil right now - we had a wonderful collaboration with Nicaragua’s most progressive design studio NINFUS to create a better logo for the community. Together with the most active people in the community we went on several iterations until we came up with this proposal. The new logo looks really great and is much more practical than before, as this has less colours and works also in smaller scales.

An internet of three classes

Net-Neutrality violations lead to a dark age for an Internet of opportunities and social development in Nicaragua

The base of a free Internet, where all information packages are treated equally without any discrimination is in danger. In Nicaragua, these developments already lead to an internet of three classes, where the poorest have least opportunities. And very remarkably, the people fall blindly into the shiny lies of the telecommunication industry.

Digital development that does not protect the Nicaraguan people

The pros and cons of a law proposal for the 'Promotion and Development of the National Broadband Network of Telecommunication Services' in Nicaragua

Not everything in the world is just black and white. And this applies also to the new initiative for the ‘Law for the Promotion and Development of the National Broadband Network of Telecommunication Services’. There are good aspects, but there are also others that leak of profoundness and some should be criticized and modified in the interest of the Nicaraguan people.

State of the internet in Nicaragua

Net neutrality, surveillance, censorship and the ISPs

All over the world discussions are emerging on net neutrality, online censorship and surveillance as urgent topics. As we can see, companies try to sell the internet service by service or even the data a about their clients in order to make more money off of their clients. And as well as some governments who’s aim is to control their citizens by violating their principals of a neutral web, free access to information and collecting data by spying on the population. Still, there are some countries, Nicaragua being one of them, that are (almost) not suspects to investigation. As a resident of this lovely country, I would like contribute by giving an overview of issues I personally am aware of, but taking into account that this article cannot be claimed fully accurate.

ManaguaMapping Party

Mapping the bus lines of Nicaragua's capital

At the first OpenStreetMap event in Managua the Mapertulia last December we initiated the idea of getting the information about bus lines in Managua mapped collaboratively. So we started now with a Mapping Party: A whole (sun)day beginning with an introductory session in the morning, then field work – mapping in the buses. After lunch another workshop about how to introduce the obtained information from the morning into OpenStreetMap, the wonderful world wide free and open map available for everybody to use or build upon it in any way. And in the afternoon coffee, fruit drinks, later some beers, sticking together and working, inserting the newly mapped bus lines into the global server.
