Data formats for M4OPS
« on: 24 January 2017, 17:39:17 »
The main data format used internally by M4OPS for its features layers is GeoJSON, which is a version of JSON designed for geographic data. We use the EPSG:4326 CRS, which is the same as Google Maps and many other systems.

There are many other formats in which feature data can be created, such as 'shape files', see eg the Glossary. Most of these can fairly easily be transformed into GeoJson by:
  • asking Peter to do it (and he is happy to do this for now)
  • importing the data into QGIS and saving it as GeoJSON - specifying the EPSG:4326 CRS
  • convert it using a service such as MyGeodata Cloud (free for smaller datasets)

M4OPS has its own conversion utilities to and from CSV, which is designed for simple datasets. As usual please discuss your use with Peter.

Having said all this, it is possible that with users' experience Peter decides to enhance M4OPS to cope with other formats - please ask.
