Last April 6th 100% of the Mexico Telenav’s team (Andrés Ortiz 50% and Miriam Gonzalez 50% 😀 ) presented the results of Import Project INEGI National Geostatistical Framework. The meeting point was the Felina bar on the edge of Condesa and Escandon neighborhood.

Andres_presentando Miriam_presenta Image by @Tlacoyodefrijol More than 20 people booked and came to the appointment. The project was originally announced in May 2015 with much skepticism because this was the first time a project of such magnitude was taking place in Mexico and the OpenStreetMap community in Mexico at that time was very disperse.

Before_import Image by Ruben @Mapbox Many import projects have been conducted in many parts of the world, such projects have helped (mostly) to create the map of the world that we have today and Mexico was going to be part of them. People with extensive knowledge in imports formed part of the project including Victor Ramirez, Ernesto Carreras, contributors od OpenStreetMap Puerto Rico and Rafael Avila, a HOTOSM collaborator and expert in African countries imports. At the beginning of the project we realized that there were only 69 valid administrative boundaries (although in the image it looks more than 69, these lacked the tag SOURCE which made them invalids) and the end of the Import project the team had added 2,457 administrative boundaries with tag Source = INEGI MGN 2014 v6.2

After_Import Image by Ruben @Mapbox To the #HappyMappingHour diverse OSM contributors atended such as geographers, developers, archeologists and also Armando Aguiar – INEGI IT Services Director witnessed how the Open Data Inegi released at the end of 2014 has been in benefit of OpenStreetMap. Let me share some statistics:

Quick Statistics:

Node numbers/Ways/ Deleted relations

500K / 2k / 500 Node numbers/ Ways / Added relations

1000K / ~4k / ~1050 Number of hours dedicated :

250+ NUmber of administrative boundaries added:

2,457

Now that the map has de MGN boundaries as a reference mappers as Irk_Ley have been investigating the local laws of the states of Veracruz and have been reviewing historical maps of the Map Library Manuel Orozco. These mappers will be verifying and correcting those limits which have differences with the MGN when they have the backup of the documentation of the local law.

Here you will find the presentation of #HappyMappingHour and if you want more technical details we suggest you check the following blogs and the wiki.

You can contact them directly if you have any questions or comments for them.

What are the next challenges?

Evaluate data from the National Road Network and create a joint project with Mexico OpenStreetMap community to carry out its import. It is also in the radar create a tool where information from OpenStreetMap in Mexico is a kind of “inspector” to send feedback to INEGI about possible shortcomings or errors can be corrected and improved thanks to contributors OpenStreetMap but first we need more discussions with the local community.
