Cadastral land surveyors are licensed by state governments. In the United States, cadastral surveys are typically conducted by the federal government, specifically through the Cadastral Surveys branch of the Bureau of Land Management (BLM), formerly the General Land Office (GLO).[10] In states that have been subdivided as per the Public Land Survey System (PLSS), the BLM Cadastral Surveys are carried out in accordance with that system. This information is required to define ownership and rights in real property (such as land, water, mineral, easements, rights-of-way), to resolve boundary disputes between neighbours, and for any subdivision of land, building development, road boundary realignment, etc.
The aim of cadastral surveys is normally to re-establish and mark the corners of original land boundaries. The first stage is to research relevant records such as land titles (deeds), easements, survey monumentation (marks on the ground) and any public or private records that provide relevant data. The job of a boundary surveyor retracing a deed or prior survey is to locate such monuments and verify their correct position. Over time, development, vandalism and acts of nature often wreak havoc on monuments, so the boundary surveyor is often forced to consider other evidence such as fence locations, woodlines, monuments on neighboring property, parole evidence and other evidence.
Monuments are marks on the ground that define location. Pegs are commonly used to mark boundary corners, and nails in bitumen, small pegs in the ground (dumpys) and steel rods are used as instrument locations and reference marks, commonly called survey control. Marks should be durable and long lasting, stable so the marks do not move over time, safe from disturbance and safe to work at. The aim is to provide sufficient marks so some marks will remain for future re-establishment of boundaries. Examples of typical man-made monuments are steel rods, pipes or bars with plastic, aluminum or brass caps containing descriptive markings and often bearing the license number of the surveyor responsible for the establishment of such. The material and marking used on monuments placed to mark boundary corners are often subject to state laws.

I Use AutocadMap 3D, it has the classic Autocad + survey features + map generation + geographical coordinates + database management, in my opinion far better than Arcgis, Arcview, Mapinfo and you can export info to most of them.You can go to the free options to view or manage the gis like Tupac says, there are some free programs for Windows too.
In first instance under civil 3d you can create parcel, lots, or whatever you want to call this entity, from basic elements like lines, arcs, polylines. Automaticly it creates a database of parcels that you can call, manipulate, draw area tables, bearings, etc. This database can be read under the module map. And can easily be read by arcgis or any other map software. The number of the parcels are managed carefuly because it does not allow repeted numbers for parcels.... Just autocad is for drawings only not manage databases (as far as i know) although there are some plugins like civil cad that might be installed and this is a helpful software, light and works for example if you are working for an urban planner or developer that needs to make single plats for aproval in the cadaster office... (that is the practice in my home country that might differ from place to place)
Akpa, I think it depends on how you would like to manage the information, you could use arcgis for cadastral databases, or land desktop (the map module) if you make surveys and then create maps. not really sure but I think now is just civil 3d (by autodesk). what we do in the office (cadaster in nicaragua) we do the surveys, process them on land or microstation (with geographics module) and then we mount it on gis. I feel more comfortable using autodesk map or land but it is just a matter of being used to....
I just installed ubuntu (operative system from linux) on my computer and i have found they have some gis softwares, the advantage of this is that you have to pay nothing by licenses, but i might not give you any comment because i have not run the gis to prove what it does and in what is good.
I found this paper on Cadastral.com by Jerry L. Wahl which addresses the complexities of double proportion in land surveying. It is very informative.

ABSTRACT
Our ever increasing ability to accurately measure make it more critical that we understand the geodetic and legal concepts behind some common survey…

Hello am Theophilus in Ghana, 24yrs and Land Survey (Engineering).And I love to join this group so I can learn more about Cadastral Surveying...honor

where are you from dude?
Thank You Tupac!!! Please tell me more about Civil 3D(by Autodesk).....What improvements those it have over the
Normal Autocad?

What Software can be used to manage cadastral information effectively.
I really need suggestions.
Thanks!
i can feel it...this is going to be a great group!
