# 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.
## Loading ESRI shapefile supply
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.
Shapefile data loading into the Map Modeller main window
CadCorp applies a random style to the data as it is loaded. The styles are applied to the borders and fills of the points and polygons within OS Open Greenspace data. Currently, there are no named object library (.NOL) files for OS Open Greenspace to style the data in CadCorp Map modeller appropriately. However, once the SLD files become available from Ordnance Survey on Github, CadCorp will be able to produce these which will allow the data to be dragged and dropped into Map Modeller and styled immediately.
#### LOADING GML SUPPLY
Although CadCorp Map Modeller will load GML files natively without translation, currently, Map Modeller does not contain the GML schema file within it to be able to interpret the OS Open Greenspace data correctly. It is, however, anticipated that this support will follow from CadCorp soon after the OS Open Greenspace data is released.

## 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-open-greenspace/os-open-greenspace-getting-started-guide/cadcorp-map-modeller.md?ask=&goal=
```
`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.
