# Location (coordinates)

* Coordinates in [EPSG 4326](https://epsg.io/4326) or [EPSG 2227](https://epsg.io/2227)
* Only EPSG 4326 coordinates can be mapped within the open data portal
* Should be represented in two columns
  * EPSG 4326: `latitude` and `longitude` or&#x20;
  * EPSG 2227: `x_coord` and `y_coord`
  * **Note:** all EPSG 4326 coordinates will be loaded into the open data portal to support mapping and presented in an additional single location column there called `the_geom`. EPSG 2227 coordinates will be represented as the two original columns&#x20;
* In positive/negative floating point
  * e.g. `latitude`: 37.761146; `longitude`: -122.436235
* EPSG should be indicated in metadata

## Is anything wrong, unclear, missing?
