A.L.T.A. SURVEY OR EXTENDED TITLE INSURANCE COVERAGE: To supply a title company and lender with survey and location data for issuing American Land Title Association or Extended Coverage Title Insurance. Such surveys typically show the relationships of existing improvements on a parcel of land relative to the boundaries as defined by the deed. (A.L.T.A. or American Land Title surveys may require a boundary survey).

BOUNDARY: To locate the property corners and boundary lines of a given parcel of land. This involves record and field research, measurements and computations to set boundary lines in accordance with state law. Easement lines and encroachments may also be located in this type of survey.

CONSTRUCTION: To provide construction personnel with directions (by way of staking or other notes) for erecting improvements shown on plans for development; e.g.; roads, buildings, and pipelines.

CONTROL: To establish precise horizontal and vertical positions of points on the ground for use in boundary determination, mapping from aerial photographs, construction staking and other related purposes.

SITE PLANNING: A combination of boundary and topographic surveys for site plan preparation to be used for designing improvements or developments prior to construction, often required as part of a development permit application.

SUBDIVISION OR PARTITION: To subdivide or partition a tract of land into smaller parcels, showing property corners and survey data on a map in conformance with local and state law.

TOPOGRAPHIC: To locate topographic features of the land–natural and man made; for example; buildings, improvements, fences, elevations, trees, streams, and contours (e.g., lines of equal elevation). This type of survey may be required by a governmental agency or may be used by engineers and/or architects for design of site improvements or developments. It is also an excellent management tool for large tracts of forestland. Such a survey is not necessarily limited by property boundaries.
