Skyline 可以连接外部的数据源，包括SQL Server，Oracle ，excel，mySQL，SQlite,WFS.......

连接字符串如下：例如连接shp文件，为“FileName=C:\\sample.shp;TEPlugName=OGR;“

§   TEPlugName=OGR –

·          Shapefile:
“FileName=FullPathToShapeFile”
Where
FullPathToShapeFile defines a full path to the shapefile.

·         
DGN file:
“FileName=FullPathToShapeFile”
Where
FullPathToShapeFile defines a full path to the DGN file.

·         
DXF file:
“FileName=FullPathToShapeFile”
Where
FullPathToShapeFile defines a full path to the DXF file.

·         
Oracle Spatial:
“OGRConnectionString=
OCI:userid/password@database_instance:table,table”.
Where
userid/password defines respectively the user name and password required
for connecting to the server, database_instance defines the Oracle Net
Service name, and table defines the table to access.

·         
PostgreSQL extended with the PostGIS spatial data
support:
“LayerName=LayerName;OGRConnectionString={
PG:dbname=’databasename’}”
Where databasename defines the
database name.
Additional parameters may be provided as required, e.g. {
PG:dbname=’databasename’ host='addr' port='5432' user='userid'
password='password'}.

·         
MS SQL Spatial:
“OGRConnectionString={
MSSQL:server=servername;database=databasename;UID=userid;PWD=password;Tables=table}”
Where
servername defines the server name, databasename defines the
database to connect to, userid and password define the user name
and password respectively, and table defines the table to access.

·         
SQLite:
“FileName=FullPathToShapeFile;LayerName=LayerName”
Where
FullPathToShapeFile defines a full path to the SQLite file,
LayerName defines the name of the layer to be loaded.

§  
TEPlugName= WFS – Used to load layers from Web Feature Server
(WFS). Additional parameters are required (mandatory fields are bolded):

·         
Server:
“Server=ServerURL”
Where ServerURL
defines a full URL to the server.

·         
WFSVersion:
“WFSVersion =Version”
Supported
Version values are “1.0.0” and “1.1.0”.

·         
LayerName:
“LayerName=LayerName”
Where
LayerName defines the name of the layer to be loaded.

·         
User:
“User =UserName”
Where UserName defines
the user name required to connect to the server.

·         
Password:
“Password=Password”
Where Password
defines the user name required to connect to the server.

·         
Lat-Long or Long-Lat coordinate
format:
“CRS_XY_OR_YX=Format”
Supported Format
values are “1” for Long-Lat and “2” for Lat-Long.

§  
TEPlugName=GeoDatabase – Used to load layers from a Personal Geodatabase
file. Additional parameters are required (mandatory fields are bolded):

·         
LayerName:
“LayerName=ServerURL”
Where
LayerName defines a full path to the GeoDatabase file.

·         
TableName:
“TableName =TableName”
Where
LayerName defines the name of the table containing the layer to be
loaded.

§  
TEPlugName= DSN – Used to load layers from an ODBC database
connection. Additional parameters are required (mandatory fields are
bolded):

·         
DSNPlugName:
“DSNPlugName=PlugName”
Where
PlugName defines the ODBC driver. For example: “Microsoft
Access(*.mdb)”.

·         
DSNConnectionString:
“DSNConnectionString=ConnectionString”
Where
ConnectionString defines the DSN connection string as required by the
defined driver.

·         
DSN_X_Field:
“DSN_X_Field=X”
Where X defines
the database field name containing the X coordinate.

·         
DSN_Y_Field:
“DSN_Y_Field=Y”
Where Y defines
the database field name containing the Y coordinate.

·         
DSN_AltitudeField:
“DSN_AltitudeField=Altitude”
Where
Altitude defines the database field name containing the altitude
value.

·         
TableName:
“TableName =TableName”
Where
LayerName defines the name of the table containing the layer to be
loaded

重点来了。实际的例子：

excel： "FileName=D:\\demo.xls;LayerName=test;DSN_X_Field=L;DSN_Y_Field=B;DSN_AltitudeField=H;TEPlugName=OGR;"
