Abstract
Мета роботи – запропонувати методику створення геоінформаційного онлайн-ресурсу для управління
Лісовогринівецькою ОТГ. Для реалізації поставлених завдань розроблено технологічну схему, що складалася
з 9 етапів роботи. Перший етап передбачав збір та аналіз різнорідних даних як векторного, так і растрового
форматів на територіюЛісовогренівецької об’єднаної територіальної громади. На другому етапі, за допомогою
програмного забезпечення Global Mapper, всі файли векторних даних у форматах *.dxf та *.dmf, що були раніше
отримні, конвертовано у формат *.shp для подальшого їх опрацювання в ПП ArcGIS. Внаслідок конвертації,
отримано графічні і атрибутивні дані в потрібному форматі і згідно шарів, які вони містять, відредаговано базу
геоданих з умовними позначеннями згідно класифікатору для створення планів масштабу 1:2000. На
наступному етапі постало завдання уніфікації бази даних конвертованих файлів, так як векторні дані створено
з різною побудовою атрибутивних таблиць. Окрім цього, виникла необхідність внесення векторних даних у
відредаговану базу геопросторових даних. Для цього написано скрипт на мові Python, що перебудовує
The aim of the work is to propose a method of creating a geographic information online resource for the management of Lisovohrynivetska UTC. To implement the tasks, a technological scheme was proposed, which consisted of 9 stages of work. The first stage involved the collection and analysis of disparate data in both vector and raster formats on the territory of the Lisovohrenivetska united territorial community. In the second stage, with the help of Global Mapper software, all vector data files in *.dxf and *.dmf formats, which were previously available, were converted to *.shp format for further processing in ArcGIS software. As a result of the conversion, graphic and attributive data were obtained in the required format and according to the layers they contain, the geodatabase with symbols according to the classifier was edited to create 1: 2000 scale plans. The next step was to unify the database of convertible files, as vector data was created with different construction of attribute tables. In addition, there is a need to enter vector data into the edited geospatial database. To do this, a ArcPy script was written that rearranges attribute tables and enters data into a geodatabase. Adjusted and populated the attribute database of vector objects for those columns where there was no information. The penultimate step was to develop the structure of the geoportal on the basis of ArcGIS-online to download the geodatabase to Lisovohrynivetska UTC on the server, to enable their external use with a unique login and password. The last step, after creating the structure of the geoportal, was to upload vector and raster geodata prepared by ArcGIS to the geoportal. As a result of the realization of the set purpose the technique of creating the geoinformation online resource for the management of the united territorial community is offered and described. During the implementation of the method the data of 24 disparate vector layers for the Lisogrynivtska community of Khmelnytsky region were processed and converted. Raster cartographic materials for UTC were collected and processed. The geodatabase according to the classifier for scale 1: 2000 is created. The structure of the geoportal based on the ArcGIS-online kernel with a connected map-base based on the online resource GoogleMaps, where all processed materials are downloaded, has been developed. The scientific novelty is to develop the concept of accumulation of heterogeneous vector and raster geospatial data in one geodatabase, by converting them into a specific format. Additional modules have been written in ArcPy to unify the database structure. Implemented geoinformation system is located on the geoportal and is designed for management decisions of community leaders. In addition, the created GIS can be used for land management and surveying work on community sites.
