Trouble with EPSG or CRM

The EPSG code is required for a successful upload because it tells us what coordinate system your file is using. A Coordinate reference system (CRS) defines, with the help of coordinates, how the two-dimensional, projected map is related to real locations on the earth.

Most geographic information systems (GIS) and GIS libraries use EPSG codes as Spatial Reference System Identifiers and EPSG definition data for identifying coordinate reference systems, projections, and performing transformations between these systems.

EPSG is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement. Each entity is assigned an EPSG code between 1024-32767, along with a standard machine-readable well-known text representation. 

You can visit https://epsg.io/ for more information on which code is applicable to your data.
