Using of laser scanning data and technology in Estonia

Antud bakalaureusetöö eesmärgiks oli uurida terrestrilise- ja aerolaserskaneerimise tehnoloogiat ning andmete kasutamist Eestis. Autorid otsivad vastuseid järgmistele küsimustele: millist riist- ja tarkvara kasutatakse Eestis; kuidas andmeid hangitakse; milline on kasutatav tarkvara ning milliseid kitsaskohti nähakse andmete, tehnika ja tarkvara ostmisel ning omamisel. Käesoleva bakalaureusetöö käigus koguti andmeid veebipõhise ankeetküsitluse abil, mis saadeti laiali erinevatele geodeesiafirmadele üle kogu Eesti, kes on oma tegevuses registreerinud laserskaneerimise erivorme. Samuti saadeti küsitlus erinevatele ülikoolidele. Uurimustöös selgitati välja, kui paljudel Eesti ettevõtetel ja teadusasutustel on endal kasutusel laserskaneerimise tehnoloogiat ning kui palju kasutatakse laserskaneerimise andmeid. Tulemustest järeldati, et terrestrilist laserskaneerimise tehnoloogiat kasutatakse Eestis rohkem kui aerolaserskaneerimist, kuid aerolaserskaneerimise andmeid kasutatakse enim. Tehnika soetamine on kulukas ning kulu ja tulu suhted ei ole paigas. Leiti, et kasulikum on osta andmeid sisse kui soetada endale tehnika, mille oluliseks põhjuseks on tellimuste vähesus,aeglane tasuvus ning tehnoloogia kiire vananemine.The aim of this bachelor's thesis was to get an overview of terrestrial and airborne laser scanning technology and the use of laser scanning data in Estonia. The research questions of the authors were: what kind of technique and technology are used in Estonia; how companies get data; what kind of software is in use and which are the problems of buying and owning the data, technique and technology. The data was collected by using the inquiry based on the Internet. The inquiry was sent to all companies involved with geomatics who were expected to be in contact to different fields of laser scanning. This inquiry was also attended by some universities. It was found out how many Estonian companies and scientific institutions own the technology of laser scanning as well as how much the data of laser scanning is used. The results display clearly that that terrestrial laser scanning technology is more popular than airborne laser scanning technology, but using the airborne laser scanning data is more common. It was also found out that purchasing technique is expensive and the profit and costs are not in balance. It also came out that it is more profitable to buy data than technique. The expiration and updates are expensive, therefore the companies do not see the value of having their own technique
