1. A computing system, comprising:

  • at least one processor; and

    memory including instructions that, when executed by the processor, cause the computing device to;

    determine a magnification level of a region for testing;

    generate, for the region at the determined magnification level, at least a first map using a first rendering engine and a second map using a second rendering engine, the first map and the second map each including a plurality of corresponding map labels;

    recognize, in each of the first map and the second map, text associated with each of the plurality of map labels using an optical character recognition (OCR) engine; and

    compare recognized text of each map label from the first map to each corresponding map label from the second map to identify a level of severity of at least one of an error or an inconsistency, the level of severity based at least in part on at least one of a type of the error or a type of the inconsistency.
