Colombia/Project-Road Names
Colombia Road Name Project will use datasets which are shapefiles from the IGAC covering Colombia. Permission has be given to use this data.
About
Kaart will use data provided by Colombia's Instituto Geográfico Agustín Codazzi with OSM.
Kaart will continue efforts to ensure effective communication with Colombia's OSM community throughout the project process.
Project Outline
- Develop tools to efficiently and accurately convert .shp files to .osm.pbf and accurately map attributes
- Develop processes to edit and validate data using JOSM (including custom paint styles and validators)
- Create projects for each district using an instance of the OSM_Tasking_Manager
Goals
To contribute up-to-date data for the road networks of Colombia by updating missing geometry and road names.
Schedule
- Manual editing and validation using JOSM - April 2020 → August 2020

Data
OSM Data Files
OSM data will be processed and delivered on a state by state basis.
Methods
- Automated tool to prepare data for conflation
- Automated tool to conflate data and output OSM_XML files
- Progress tracking will be done using an instance of the OSM_Tasking_Manager
- Manual processes for editing and validating data in JOSM
Data Preparation
Data Reduction & Simplification
Our team developed a tool to automate the process of converting the shapefile data.
Arguments
- Shapefile
- Translation file (compatible with ogr2osm)
Tools/Modules
Process
- Executes spatial analysis to extract Shapefile data within each department into individual Shapefiles
- Converts Shapefile to .osm and translates attributes to OSM tags
- Converts .osm file to .osm.pbf
Each task will have one OSM_XML file to compare names in OSM with names from data source.
Once we have converted the data into OSM_XML for a department, we can then create an OSM_Tasking_Manager project for the department and use the task bounds to take the appropriate Bounding_box of the converted files as a separate layer into JOSM.
All of these processes have been extensively tested and their outputs will be closely monitored throughout the project process.
Data Transformation
Prior to using the tool described above, we make sure the data is encoded using ISO-8859-1 and is projected to WGS84 using QGIS.
Data Transformation Results
OSM XML files will be created on a state by state basis to keep the data as accurate as possible.
Data Workflow
Team Approach
The development of the tools and the actual project will be handled by the Kaart Team with constant collaboration with the local Colombia community.
References
Workflow
Once the user selects a task, they will follow the following workflows:
Missing Geometry
- Download task from tasking manager.
- Correct geometry
- Add missing geometry
- Run JOSM/Validator with the custom validator
- Upload changes using Agregada geometría faltante utilizando datos de IGAC. #Kaart
- Source tag IGAC
Road Names
- Use the name layer to manually verify road names
- Run JOSM/Validator with the custom validator
- Upload changes using Actualicé nombres de vías utilizando datos de IGAC. #Kaart
- Source tag IGAC
QA
QA will be incorporated into the OSM_Tasking_Manager's validation. We will be using custom validators as well.
You can view changesets using OSMCha.
