Types Of Surveys
A surveying standard jointly proposed by the American Land Title Association and the American Congress on Surveying and Mapping that incorporates elements of the boundary survey, mortgage survey, and topographic survey. ALTA/ACSM surveys, frequently shortened to ALTA surveys, are often required for real estate transactions.
The actual physical extent of property ownership, typically witnessed by monuments or markers, (such as iron rods, pipes or concrete monuments in the ground, and also nail and discs or other types of monuments in hard surfaces) are measured, and a map, or plat, is drawn from the data.
A survey to determine if a structure or object is changing shape or moving. The three-dimensional positions of specific points on an object are determined, a period of time is allowed to pass, these positions are then re-measured and calculated, and a comparison between the two sets of positions is made.
The position of the house is measured before it is finished being built. Usually used by the builder for his construction draw.
A simple survey that generally determines land boundaries and building locations. Mortgage surveys are required by title companies and lending institutions when they provide financing to show that there are no structures encroaching on the property and that the position of structures is generally within zoning and building code requirements. Some jurisdictions allow mortgage surveys to be done to a lesser standard. However, in Florida state minimum standards require the same standard of care for mortgage surveys as any other survey. The resulting higher price for mortgage surveys has led some Title Insurance Companies to accept "Owner Affidavits" and an old survey in lieu of a new survey signed or sealed by a surveyor.
The finished house and driveway are measured, and all markers on the boundary are indicated. This is provided to the new owner when the lot is sold.
A proposal for a house or other building and driveway or parking lot are added to a lot for construction permitting.
A plot or map based on a survey of a parcel of land. Lines are drawn inside it, indicating the location of roads and lots. Plats are usually discussed back and forth between the developer and the surveyor until they are agreed upon, at which point pins are driven into the ground to mark the lot corners and curve ends, and the plat is recorded in the County in which it is located. In most Florida Counties, the recording or filing of a subdivision plat is highly regulated. The final map or plat becomes, in effect, a contract between the developer and the city or county, determining what can be built on the property and under what conditions. It also must meet State of Florida Statutory requirements prior to recording
A survey that measures the elevation of points on a particular piece of land, and presents them as contours on a plot.
A survey conducted with the purpose of mapping the seabed for navigation, engineering, or resource management purposes. Products of such surveys are nautical charts. .
Construction surveying (otherwise "lay-out" or "setting-out"):
The process of establishing and marking the position and detailed layout of new structures such as roads or buildings for subsequent construction. In this sense, surveying may be regarded as a sub-discipline of civil engineering.
Used to accurately assess the relationship of archaeological sites in a landscape or to accurately record finds on an archaeological site.
