# CadCorp Map Modeller

CadCorp Map Modeller is a commercial GI application which can load a wide variety of data formats. It also comes with a free software viewer application called CadCorp Map Express.

* To load the ESRI shapefile data, open a file explorer window in Windows and simply drag and drop the .shp files into the Map Modeller window.

CadCorp applies a random style to the data as it is loaded. The styles are applied to the borders and fills of the polygons within OS MasterMap Greenspace Layer data. As of March 2018, in their build of Map Modeller version 8.0\_2549, CadCorp have added support for loading the GML supply format of OS MasterMap Greenspace Layer data (see below).

Users of CadCorp Map Modeller SIS version 8.0 can obtain an update of the software to version 8.0\_2549 from CadCorp. This version of Map Modeller will now load the .GML version of OS MasterMap Greenspace Layer data. To load the data, open CadCorp Map Modeller and click ‘Add Overlay’.

   Map Modeller will read the .GML files and load in the OS MasterMap Greenspace Layer data using the predefined correct styling for the product. If required, the overlay can be exported to a spatial database and the theme re-applied to the database. The expression used by the theme may need to be altered, depending on the database used for the export.<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.os.uk/os-downloads/products/land-and-terrain-portfolio/os-mastermap-greenspace-layer/os-mastermap-greenspace-layer-getting-started-guide/cadcorp-map-modeller.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
