I’m Cesar Alfaro from a remote place in the Peruvian Andes, 3 years ago I started interacting with OpenStreetMap, and as it had to be, my first OpenStreetMap edits I did in the place where I was born, then I was part of the data team of Mapbox and Develment Seed respectively, where I officially started adding large-scale, high-quality data to OpenStreetMap all over the world, you can take a look at my HDYC profile. Below I am going to mention an overview of the most important mapping projects I have worked on.
I’m an active collaborator of HOT mapping and validating efforts. Below the list of projects I have collaborated.
To-fix is a tool used to improve OpenStreetMap data around the world, mainly I was focused on correcting connectivity issues between roads that negatively impact on possible routing data. I used tofix-Web (Currently, nobody maintains this side) and tofix-plugin. Take a look at the types of map issues that were corrected in this Diary Post.
At the end of 2016, I was also part of the road network mapping and alignment efforts in Taiwan. The overall project consisted of 43 tasks management tasks covering 27,000 square kilometers, which is 74% of total area of the country. Diary Post.
This was one of the most important projects I have participated in, since for the first time we included the help of Machine learning (ML) to our workflow. In summary, it was created a ML model to detect high voltage towers within satellite imagery, which helped us to increase speed and accuracy in high voltage towers mapping. Blog Post.
Together with the OSM community I participated in the repair of data affected by the OpenStreetMap redaction in Peru, this was done by DWG to delete original data added to OpenStreetMap with infringed copyright.
I participated in the improvement of the OpenStreetMap road network of the USA using information from TIGER 2014 and 2016. Ticket-1, Ticket-2, OSM Wiki .
I was part of the mapping of buildings and roads within SEZ, since these can be used as indicators for the analysis and study of the growth, development and impact of a SEZ over time. Ticket.
I was also part of navigation mapping efforts in US:
Buildings Import in Los Angeles, I participated in the validation and improvement of imported buildings in Los Angeles. Ticket, My import user.
Schools Import in Peru, I participated in the importation of over 75,000 schools to OpenStreetMap in Peru. Diary Post, My import user.
I am getting involved in political affairs of my province, and from this side I will encourage the release of public institutions geographic data such as the cadastral information of the municipalities, and of course I will make sure to talk to them about OpenStreetMap and teach how to contribute to the map, to extract data, process it and create your own map.
