1. What do the acronyms TLS, MTLS, ALS, LIDAR, LASER, TOF, PS refer to? TLS (TerrestriaTLS (Terrestrial Laser Scanning) - viitab otseselt maapealsele, peamiselt staatilisele, laserskaneerimisele. Kasutatakse ka nimisõnana. Mobiilne terrestriline laserskaneerimine (MTLS) Mobiilset ehk dünaamilist laserskaneerimist kasutatakse peamiselt sõiduki peal oleva seadme abil teede ja tänavate mõõdistamiseks. ALS - aerolaserskaneerimine (Airborne Laser Scanning) –viitab otseselt lennuki või helikopteri pealt laserskaneerimisele. LIDAR (LIght Detection and Ranging) – viitab kaugseire tehnoloogiale. Laialdaselt kasutatakse lennuki või helikopteri pealt skaneerimise kohta, kuigi nimetus ei ole viidatud laseri kasutamisele ega muule tehnoloogiale LASER - (Light Amplification by Stimulated Emission of Radiation ek. valguse võimendumine stimuleeritud kiirguse kaudu) on seade, mis võimaldab kiirata kitsaid, koherentseid ja monokromaatilisi valguskimpe. Laseri abil

It involves identifying a specific group or category of people and collecting information from some of them in order to gain insight into what the entire group does or thinks; however, undertaking a survey inevitably raises questions that may be difficult to answer. How many people need to be surveyed in order to be able to describe fairly
