cadastral survey

A cadastral survey is the systematic measurement and mapping of land parcels to establish legal boundaries and property ownership for administrative and taxation purposes.

Cadastre

A comprehensive public record system that documents the extent, value, and ownership of land parcels within a jurisdiction.

canopy filtering

A surveying technique that removes vegetation canopy data from LiDAR point clouds to reveal ground surface elevations.

Carrying Case

A protective container designed to safely transport and store surveying instruments and equipment.

Cartography

The art and science of creating maps to represent geographical features and spatial relationships on Earth's surface.

Central Meridian

A reference meridian used in map projections to minimize distortion by serving as the central line of longitude for a projection zone.

check point

A marked location of known position used to verify the accuracy of surveying measurements and equipment calibration.

chi square test

A statistical test used to determine if there is a significant association between categorical variables by comparing observed and expected frequencies.

chm

Chm is a compiled help file format used for displaying documentation and assistance information in software applications.

closure error

The discrepancy between the starting and ending points of a surveyed traverse or polygon, indicating accumulated measurement inaccuracies.

CloudCompare

CloudCompare is an open-source software application designed for processing, visualizing, and analyzing 3D point clouds and triangulated meshes.

COGO

COGO is a computer system used in surveying to calculate coordinates and distances based on bearings, angles, and traverse data.

collimation error

A systematic error in surveying instruments where the line of sight does not coincide with the optical axis, causing inaccurate measurements.

Confidence Interval

A range of values that likely contains the true population parameter based on sample data.

control network

A system of precisely positioned points established across a survey area to provide accurate reference coordinates for all subsequent surveying and mapping work.

Coordinate System

A framework of reference lines or axes used to precisely locate and identify positions of points on Earth's surface or in space.

Corner

A point where two or more property lines, boundaries, or survey lines meet at an angle.

Corridor Mapping

The systematic process of surveying and documenting linear features and land characteristics along a defined path or route.

CORS Network

A system of continuously operating reference stations that provide real-time satellite positioning data for surveying and mapping applications.

cross section

A vertical slice through the earth showing the elevation profile of the land surface and subsurface features along a survey line.

Cut Fill

Cut fill is the process of excavating earth material from higher elevations and using it to build up lower elevations during land development and construction projects.

cyclone

A cyclone is a rapidly rotating storm system characterized by low atmospheric pressure at its center and strong winds spiraling inward.
