Simon Hunt | f817338 | 2015-01-13 14:12:09 -0800 | [diff] [blame] | 24 | The Map Service provides a simple API for loading geographical maps into |
| 25 | an SVG layer. For example, as a background to the Topology View. |

Simon Hunt | f817338 | 2015-01-13 14:12:09 -0800 | [diff] [blame] | 27 | e.g. var ok = MapService.loadMapInto(svgLayer, '*continental-us'); |

Simon Hunt | f817338 | 2015-01-13 14:12:09 -0800 | [diff] [blame] | 29 | The Map Service makes use of the GeoDataService to load the required data |
Simon Hunt | a7b6a6b | 2015-01-13 19:53:09 -0800 | [diff] [blame] | 30 | from the server and to create the appropriate geographical projection. |
