Surveying & Architects

This page is help to all of you for knowing about Land Surveying and Architectural Engineering......

Surveying & Architects is a personal development network for geospatial professionals. We believe the best technical support that a land surveyor can have is the support of another experienced land surveyor. On Surveying & Architects, geomatics, geospatial and surveying professionals have been given the opportunity to build and grow their own global support network which can be accessed from any internet connection, mobile device or telephone. Our dedicated social support groups are based upon location, equipment manufacturers, theme or surveying related topic. Surveying & Architects has become the world's largest and most helpful resource for professional surveyors anywhere on earth, translatable into every language and packed with surveying videos, articles, discussions and photos. If you are a land surveyor or were one in a previous life, share your surveying life with us on Surveying & Architects. We promise to return the favor.

A single survey is made of at least a sample (or full population in the case of a census), a method of data collection (e.g., a questionnaire) and individual questions or items that become data that can be analyzed statistically. A single survey may focus on different types of topics such as preferences (e.g., for a presidential candidate), opinions (e.g., should abortion be legal?), behavior (smoking and alcohol use), or factual information (e.g., income), depending on its purpose. Since survey research is almost always based on a sample of the population, the success of the research is dependent on the representativeness of the sample with respect to a target population of interest to the researcher. That target population can range from the general population of a given country to specific groups of people within that country, to a membership list of a professional organization, or list of students enrolled in a school system (see also sampling (statistics) and survey sampling).
Survey methodology as a scientific field seeks to identify principles about the sample design, data collection instruments, statistical adjustment of data, and data processing, and final data analysis that can create systematic and random survey errors. Survey errors are sometimes analyzed in connection with survey cost. Cost constraints are sometimes framed as improving quality within cost constraints, or alternatively, reducing costs for a fixed level of quality. Survey methodology is both a scientific field and a profession, meaning that some professionals in the field focus on survey errors empirically and others design surveys to reduce them. For survey designers, the task involves making a large set of decisions about thousands of individual features of a survey in order to improve it....
