During the last months, DevSeed data team, as active members of the OSM community in Peru, along the support of other members of the community, imported around 7,933 health centers throughout Peru between health centers of different categories and from different operator institutions both public and private.

Once the importation was completed, about 6,200 new health centers were added to the map, and to those already existing on the map we added more details, such as; operator, telephone, address, category, among others. This was possible by the data found in the Peru’s National Open Data Portal, so, thanks to the open data, we were able to add new health centers to OSM and improve the map in Peru, especially in the rural areas where this type of information was poor and in many other areas they simply did not exist. But currently, after this importation, there are more than 8,600 health centers across Peru, in comparison to the 2,400 that were on the map.

On January 16 of this year, the Peruvian company Guiacalles requested to delete private data that was added in OpenStreetMap without considering the copyright.

This copyright infringement was due to an import of data by TELCOM IP that was carried out in Peru 7 years ago. Since it was impossible to verify the original license of the imported data, the DWG did a redaction to delete the original data. This affected 28 cities of the country, removing everything from main streets to pedestrian streets, and loosing all the edits of the OSM community that were made on top of that data in the last 7 years.

Our workflow during and after the redaction

The #osmPe channel on telegram was the main communication channel for coordination of the whole redaction process, as well as tickets in the repository of osm-peru-redaction.

Natural disasters happen at anytime and anywhere in the world. Unfortunately on this occasion, an 6.8 magnitude earthquake affected the southwest Peru that mainly hit the Arequipa and Ayacucho departments.

Given this, the OSM Peru community called for a #MapeoColaborativo, where Development Seed’s data team as part of the community has participated actively in mapping and validation of the 6 tasks that were opened for the affected provinces, in which more than 7000 objects between buildings and roads were mapped. Incuyo province 100% mapped and validated

These data are important to bring humanitarian aid and give immediate response to the affected places and are available for use by Government institutions such as National Emergency Operations Center (COEN), National Institute of Civil Defense (INDECI), and any organization or initiative that responds to emergency events.

As part of the goal of making Ayacucho the best-mapped city in Latin America, the OSM community of Ayacucho, along with the Mapbox Perú team, added 20 bus routes relations to OpenStreetMap of 22 public transport services that there are in the city.

Bus routes added in Ayacucho

During the mapping, 41 public_transport = stop_position and 15 public_transport = platform has been added/updated in downtown.

Improvement of OSM data quality using osmlint and to-fix

To help make it easier for mappers to clean up various quality issues OSM, we have used osmlint to detect dmap ata issues using javascript validators and automatically publish them as tasks daily into To-fix.

In this way mappers are solving thousands of connectivity errors, overlapping ways, unclosed ways, incorrect tags or adding missing tags on the data using satellite imagery daily. Most issues are caused by inexperienced users who may be unaware of how to use the map editor and tags correctly and can be easily fixed by experienced remote mappers. Task descriptions and instructions to fix are provided in the Github repository.

Fixing issues using To-Fix JOSM plugin

To make it even easier to cycle through a task of interest, experienced mappers can solve issues much faster using the To-Fix JOSM plugin.
