Abstract

Abstract. This research examines the problem of automation of quality control of digital topographic maps at the scale 1:50 000 of the Main State Topographic Map in Ukraine for the creation and maintaining the seamless topographic database for national needs, which is located on the Geoportal to ensure the development of the National Spatial Data Infrastructure (NSDI) in Ukraine. The authors determined stages of quality control of digital topographic maps at the scale of 1:50 000 for the automation one according to ISO 19157:2013 Geographic Information – Data quality. The realized automated quality control of geodatabases of updated digital topographic maps at a scale of 1:50 000 provides high speed and quality of validation: validation of quality data elements; validation of quality metadata; validation of positional accuracy. The software package “Validate” was developed for automation quality control geodatabases of digital topographic maps at the scale of 1:50 000 using the Python programming language to verify logical consistency, compliance with the rules of topological relationships between features on the map, availability and content of metadata. The “Validate” can be used for automation quality control geodatabase for any map scale, performing setting according to the requirements of the geospatial models.

Highlights

The seamless topographic database of the Main State Topographic Map of the scale 1:50 000 is being created for the first time in Ukraine and it will become the Core Reference Dataset for the development of National Spatial Data Infrastructure (The NSDI Law of Ukraine, 13.04.2020)
The urgent need for the creation of TDB formulates the need to increase the intellectual level of creation spatial data of topographic features and led to the emergence of new requirements for creating digital topographic maps as initial data for the seamless topographic database (Karpinskyi and Lazorenko-Hevel, 2020)
The quality control of geospatial data must correspond to the requirements of the standard ISO 19157:2013 Geographic Information – Data quality (ISO, 2013);

Summary

Introduction

The seamless topographic database (hereinafter – TDB) of the Main State Topographic Map of the scale 1:50 000 is being created for the first time in Ukraine and it will become the Core Reference Dataset for the development of National Spatial Data Infrastructure (The NSDI Law of Ukraine, 13.04.2020). The input data of the seamless topographic database are the updated digital topographic maps of the scale 1:50 000. The urgent need for the creation of TDB formulates the need to increase the intellectual level of creation spatial data of topographic features and led to the emergence of new requirements for creating (updating) digital topographic maps as initial data for the seamless topographic database (Karpinskyi and Lazorenko-Hevel, 2020). The process of creation (updating) digital topographic maps of the scale 1:50 000 have some peculiarities: automated creation of new virtual and associated features, use rules of the digital description of topographic features and rules of topological relations between features of a digital topographic map, providing of automated quality control of updated digital topographic maps, development the Geoportal project monitoring and support system for production process automation, control of implementation and simplification of access to information exchange between project participants.
