Hello all, as EPSG codes have become de-facto standard way of identifying various SRS'es in various services and other places, we need a way how to sore locations EPSG code, if it's known. Currently when creating a new location by EPSG code, this information gets lost. There is no easy way how to determine current location EPSG code required to connect any OGC WxS service. Comparing proj parameters from epsg file is not failproof.
Options: a) add a new key-value pair to PROJ_INFO + all information is stored in single place + projection information reading/writing code is already inplace - it needs to be changed to deal with a new key-value pair - breaks backwards compatibility - EPSG code might not be known for most of (existing) locations b) create a new file (epsg) in PERMANENT + doesn't affect current projection information management - information lives separate from rest of projection information - requires new functions to read/write this info I would like to hear other developer opinion before any changes to core parts are implemented.
