The library recently received information from Digimap about data being available in new formats and download delays and we wanted to share this with you. To start with:
MasterMap in New Formats
EDINA have been busy over the summer making improvements to the Data Download service and as a result you can now order OS MasterMap Topography Layer in formats ready for use in GIS or CAD software rather than having to convert the data first. We have also updated the Basket in Data Download to make it more obvious how you can do this. The data is available directly in DWG format for CAD software and File Geodatabase for ArcGIS and QGIS, see the following blog posts for more information:
Data Download Delays:
One consequence of the addition of the new formats is that it can sometimes take longer for your OS MasterMap data to arrive than it has in the past (although most of the time OS MasterMap data will be ready for download in less than 20 minutes, at busy times it can take over 2 hours to get your data) . This is a seasonal occurrence with October / November being the busiest time of the year and while we are still operating within the promise of a maximum 48 hour wait, the longer times are still catching some people out. The reason is that the conversion process to create OS MasterMap data in the new formats can take some time to run on orders for large areas. If we get many of these large orders that need conversion, all at the same time, it can cause delays even for smaller orders with no conversion requested.
We are looking at our system architecture to see how we can ensure that there is always capacity for small orders to be processed quickly, and to increase capacity for all orders in general. In the meantime there are a few measures you can take to help get your data quicker:
- Firstly try and avoid busy times, mornings are better than afternoons and the beginning of the week is better than the end.
- If you’re ordering multiple datasets, put your OS MasterMap data in a separate order. Your non-OS MasterMap data will generally be available before your OS MasterMap data.
- Order data ahead of time, particularly for practicals that require working with downloaded data.
Digimap can be accessed from the databases by subject lists on either the architecture, construction, or surveying lists.
