Many international, European, regional, and national organizations are active in spatial data collection and analysis. Their activities for spatial data management as well as the implementation of geoportals outline the need for harmonization of the infrastructures with existing data in different areas and in the forestry. The forests spatial data in Bulgaria are part of various information systems, specialized projects, and active national portals. The information process is characterized by rapid technological p...

LiDAR technology expands the possibilities for forest inventory using aerial and terrestrial scanning. A technological scheme for terrestrial personal laser scanning (PLS) has been developed in order to extract numerical tree parameters. The aim of the paper is to determine the characteristics of individual trees and average taxation indicators of forest stands via terrestrial PLS method. The PLS system includes Sensor Ouster OS1-16, mounted on a folding monopod and mini PC for control and recording of primary raw...

This study uses GIS for studying the state of forests, affected by diseases or by pests or have other kind of damages. GIS is an effective tool to examine the phytosanitary status of forests based on existing specialized data from forest management plans and data from alerts submitted to online portal of the Executive Forest Agency, Bulgaria. The spatial GIS analysis of the specialized data for a given forest management unit (State Forestry Enterprise "Chirpan", district Stara Zagora, Bulgaria) is the basis for th...

This paper focuses on the capabilities of Geographic Information Systems (GIS) to develop databases that support alternative tourism and, in particular, wine tourism in Bulgaria. The main task of the paper is to collect and integrate existing public and open-source graphical and attribute data. We use GIS tools to create a database, an online register, and an interactive map of wineries and wine houses according to Bulgarian laws and tradition. We create a specialized spatial GIS database containing administrative...

This paper explores the opportunities of using Geographic Information Systems (GIS) and data from unmanned aerial vehicles (UAVs) and satellites for effective tree health mapping and assessment of forest stands, damaged from biotic and abiotic factors. The aim is to detect affected areas with tree health problems using time series satellite images. The next step is to extract precise vector and attribute data describing the type and extent of damages using drone-captured digital images. The experimental area is pa...
