This video provides a helpful introduction into what GIS is and how it works. On the other hand, GIS provides the precise measurements and location of individual topographical features, but is less precise at determining the relative position. In general, land surveying is less accurate at measuring horizontal coordinates of topographical features, but very accurate when placing this feature in relation to other locations. Different Scopes of Precisionīoth GIS and land surveying are incredibly precise, but at for different purposes. In order to optimize the advantages of both disciplines, we need to understand how they complement each other. GIS is an accurate method for systems integration and land surveying is a useful method for canvassing. But, the truth is these two topographical methods are not in competition they are complementary tools. Many in the industry have argued that one provides more advantages or have discussed why one is better for the job at hand than the other. Historically land surveying and geographic information systems (GIS) have been compared and contrasted.
