Prerequisites for csv import: - only point data supported yet - column lon for longitude coordinates - column lat for latitude coordinates - filename must only contain alphanumerics, dashes and underscores - filename must end .csv (postgres insert function restriction) - only allowed csvdelimiter is semicolon (;) - currently only utf8 charset allowed, i.e., no umlauts, ß, etc. in csv content - numeric values in csv are inserted as text to database TODO: check: do NOT allow feature type names containing whitespaces! This will mess up queries that are not correctly url encoded or even then. NB: Conventions for new layers, datasources and workspaces: - datasource starts with prefix gd_ and concatenates workspace name - layer name (not layer title!) must not contain whitespaces and end with _gd_ plus the newly created layerId

Parameters:

sec -

ctxt -

workspace -

sridAsString -

delimiter -

fileName -

readableLayerName -

fileType -

optColumnTypes -
