Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): Place names on maps in the Internet are under observation in this work.
The goal of this work was to create heuristic rules for production and evaluation of maps in the Internet and to test the functionality of these heuristics in practice.

The first part is a literature survey.
The heuristic rules were created on the basis of cartographic literature.
The second part includes an evaluation that was made with the heuristic rules and the analysis of the evaluation results.
Evaluation was made on the scale from 1 to 5.
Place names of five different map services in the Internet were evaluated.
From each map service, 10 different map samples at four zoom levels were evaluated.
Evaluation was made by seven persons, one of whom was an expert of cartographic place names.

The evaluation showed that it is possible to evaluate place names with the created heuristics.
Some of the heuristics seem to be similar with each other, especially those relating to the location of place names, and therefore uniting those might be justified.
There were great differences between the place names on the studied map services.
The source data and the quantity of place names were factors that were affecting most to the quality of the place names.
The results show that place names on the maps in the Internet are not a reliable source of knowledge in the same sense as we are used to with printed maps in Finland.
Abstract (fin): Tässä työssä tarkastellaan verkkokarttojen nimistöä.
Tavoitteena oli luoda heuristiset säännöt verkkokarttojen nimistön tuottamista ja arviointia varten sekä kokeilla näiden heuristiikkojen toimivuutta käytännössä.

Työn ensimmäinen osa on kirjallisuuskatsaus, jonka pohjalta muodostettiin verkkokarttojen nimistön heuristiikat.
Toinen osa sisältää heuristiikkojen avulla suoritetun arvioinnin ja arviointitulosten analyysin.
Arviointi tapahtui arvoasteikolla 1-5.
Arvioitavana oli viiden eri verkkokarttapalvelun nimistö.
Kaikilta karttapalveluilta arvioitiin 10 eri karttapalaa neljällä eri zoomaustasoilla.
Arvioinnin suoritti seitsemän henkilöä, joista yksi oli kartografisen nimistön asiantuntija.

Arviointi osoitti, että luotujen heuristiikkojen avulla on mahdollista arvioida verkkokarttojen nimistöä.
Muutamat arvioinnissa käytetyistä heuristiikoista, erityisesti nimistön sijoitteluun liittyvät heuristiikat, näyttäisivät olevan samankaltaisia, joten niiden yhdistäminen voisi olla perusteltua.
Verkkokarttapalveluiden nimistöissä oli suuria eroja.
Eniten nimistön laatuun vaikuttavat tekijät olivat lähdeaineisto sekä nimistön määrä.
Tulokset osoittivat, että verkkokarttojen nimistöä ei voida pitää siinä mielessä luotettavana tiedonlähteenä kuin mihin Suomessa painettujen karttojen kohdalla on totuttu.
