Land Surveyors use markers as reference points for topographic mapping. Companies such as NRG Surveys will install a series of markers and using specialist measuring equipment will measure the precise 3 dimensional cartesian coordinates of each marker with reference to a network. The network may be a local system where it is assumed the earth is flat for small surveys but for larger surveys a 'projection' is required to accomodate the curvature of the earth. Heights are commonly referred to in relation to the geoid, the equipotential surface of the earth which would coincide exactly with the mean ocean surface, if the oceans were in equilibrium, at rest, and extended through the continents.
Colored survey markers typically indicate different types of information such as property boundaries, utility lines, or specific survey points. Each color may represent a different type of information or a particular surveying agency's standard. It is important to consult the appropriate survey plans or authorities to understand the meaning of the specific colors used in survey markers.
Survey spikes with orange ribbons typically indicate property boundaries or survey markers. These markers are often placed by surveyors to demarcate the limits of a parcel of land. It's important to respect these markers as they represent legal boundaries and should not be disturbed or removed without permission.
The word is spelled "survey."

An 8-foot offset on a boundary survey usually refers to a distance that lines are measured parallel to the boundary line or property line. This offset helps in accurately mapping out the boundaries of a property and determining the correct location of property lines.
The plural of survey is surveys.

Brush colored markers are literally markers which make brush strokes. They have feathered tips which simulate a paint brush. Some of them literally have brushes as tips. For quick, casual artwork, they are excellent to experiment with. If you are interested in watercolors, try doing a water wash, then apply these markers for an interesting soft color. They are excellent for experimenting at a very reasonable price.
Yes but it probably isn't good for you.

A DaMath board can be made using heavy cardboard for the base and colored construction paper or colored markers for the markings/decorations.
Yes, there's about 50 other colored markers.
If you mix every color together (crayon, markers, colored pencils), you will get black.
