Tobulėjant kompiuterinėms technologijoms tobulėja ir žemėlapių sudarymas, todėl atsiranda poreikis ir užrašams, taikomiems kartografijoje, analizuoti. Naujai apžvelgiama užrašų ir jų šriftų tradicijos, specifika bei komponavimas, kas ir lemia informacijos kiekį kartografiniame kūrinyje. Per didelis arba per mažas užrašų kiekis žemėlapyje, t.y. ne optimali žemėlapio tekstinė apkrova, tik apsunkina žemėlapio informacijos suvokimą. Atlikti tyrimai parodė, kad kartografinių kūrinių tekstinė apkrova užrašais nors ir yra aktuali tema, ypač leidyboje, bet Lietuvoje bei Europoje praktiškai nenagrinėta ir jokie tyrimai šia kryptimi nebuvo atliekami. Išanalizavus faktorius lemiančius žemėlapio tekstinę apkrovą, buvo sukurta metodika ir atlikti praktiniai šios metodikos tyrimai. Tyrimo metu gauti rezultatai bei jų analizė leido sukurti automatizuotą sistemą (kompiuterinę programą), kurios pagalba galima greitai įvertinti jau esamų bei naujai kuriamų žemėlapių tekstinės apkrovos laipsnį. / With the development of computer technologies, the mapping also progresses; therefore there is a need to analyze the notes used in cartography. The traditions of records and their fonts, their specifics and compilation, which determines the amount of information in the cartographical work, are being newly overviewed. Too big or too little amount of notes in the map, i.e. not optimal text load, only makes it more difficult to understand the information. Studies have shown that the topic of text load with notes of the cartographical works virtually was not analyzed neither in Lithuania nor Europe and no research was carried out, even though it is important topic, especially in publishing. After analyzing the factors which determine the text load of the map, the methodology was created and practical analysis of this methodology was performed. The results obtained in this research and their analysis, allowed to create an automated system (computer program) which helps to quickly assess the level of text load of maps, both newly created and existing ones.

The work presents a new low voltage electric network development method and a computer program implementing it. In the work is given analysis of the task actuality, review of CAD, electric circuit modeling – counting tools. It also explains the grounds why MS Visio programming environment was selected to implement the set tasks. In designed part of the system is presented systems specification, custom interface, data structure, data flow, systems functions and non functions requirements. Represented EJLPS smart shapes with graphics views and descriptions. Showed, how electric power network one-way circuit must be represented as oriented tree graph, and counting in them can be organized with searching algorithms. Made user case, static structure, component, deployment, activity and method models. Represented EJLPS subroutines and functions specification and shapes functions specification also. Systems testing was carried out using described testing methodology, tests descriptions and testing results. The work presents user documentation, with installation guide, system guide, system administrator guide and description of system functionality. In the final part of the work is presented system quality diagnosis, system development possibilities and information how the system was installed for a specific customer. Finally, a conclusion was made that MS Visio environment enabled to implement the EJLPS system specification in a cost-saving way and ensured effective searching... [to full text]
