GIS software can join the buildings to the height csv but DWG files just have the csv for a reference of heights in that area. DWG and csv cannot be linked, so we have created a new format with the building height information integrated in to the DWG information.
If the product has a resolution of 12.5cm for example, each pixel on the screen when the image is at 100% represents 12.5cm on the ground in the real world. Therefore, 12.5cm is very detailed (better quality when zoomed in) compared to 5m aerial imagery.
A raster map is an image, usually available as a JPG or TIF, much like a digital photo. A vector map will often come in formats used in CAD or GIS software which has layers you can edit or remove, with information attached to items in the map, such as measurements and labels in OS MasterMap data.

Usually when ordering mapping and data from emapsite, you are paying for a licence to use the data, either on a perpetual basis (forever) or for a period of time (often annual). If annual, you will receive an email from emapsite asking you if you would like to:
Renew your licence to use the data for a further year
Delete - confirm that you have deleted all digital copies you have of the data
Archive - you will store the data for any potential legal queries in relation to the work carried out using the data, but otherwise it will not be used
