When we receive data from the Deeds office it only contains the suburb extention (Deeds suburb) and not the City/Town information. We then group and map the extentions to a city/town inside the SAPTG Suburb layer (Suburb).
Deeds Data for Western Cape, Cape Town has only one suburb for the whole of Cape Town and that is Cape Town which makes it difficult to find property in Cape Town if one would want to search on the Deeds Suburb field.
In most of the other provinces we do do not encouter the same problem.
When searching according to Deeds Suburb, the City is ignored. The City do play a role when searching on the standard SAPTG Suburb
