1. Importing MasterMap data on one layer per MasterMap category
Using the MasterMap.dwt template in Map 3D 2006, OS MasterMap data (.gml or .gz) can be imported in two ways. The first is to import each MasterMap category (i.e TopographicArea, TopographicPoint etc) onto one Map layer. There are defined themes set to OS standards in the template Display Manager which can be used to apply classifications these layers.
a) Import the .gml or .gz file using the Map>Import menu b) In the import dialog select the MasterMap category of interest (in this example Topographic Area)
TIP: to deselect all the categories right click in the Input Layer column
For Input Layer and Drawing Layer leave the defaults (i.e TopographicArea)
c) In the data column create and Object Data table called the same as your Input Layer (i.e TopographicArea)
d) Click ‘Ok’ Depending on the MasterMap category you are importing the data will appear as black polygons, lines or points.
e) In Display Manager, make sure the Map is set to ‘MasterMap – Themes’ f) In Display manager expand the Topographic Layer folder. g) Expand the Topographic Area folder to see the pre-defined classifications h) Right click on the TopographicArea layer in Display Manager and select i) Right click on the TopographicArea layer in Display Manager and select ‘Update’ The MasterMap data will update and display as a thematic map based on OS standards 2. Importing MasterMap data on individual layers according to attribution
The second method is to import each MasterMap class (i.e Buildings, Roads etc) onto one Map layer each. There are defined layers set to OS standards in the template Display Manager which can be used to control the individual layers.
a) Import the .gz or .gml file b) In the import dialog select the MasterMap category of interest (in this example Topographic Area) - For Input Layer leave the default (i.e TopographicArea)
- For drawing layer, select to the right of the cell in the appropriate row (i.e TopographicArea)
c) In the Layer Mapping dialog, select ‘Use data field for layer name’ d) Select Descriptive Group e) In the data column create and Object Data table called the same as your Input Layer (i.e TopographicArea) f) Click ‘Ok’ The data is imported and automatically assigned to a layer in the drawing g) To control individual layers go to Display Manager and select the MasterMap – Layers map h) In this example, expand the Topography Layers folder to view the individual layer categories i) Right click on Topography Layers and click ‘Update’ |
