The document discusses the creation of a geographic database for the upper Nishava catchment area. A GIS platform was established including ArcGIS software. The database includes spatial data on boundaries, rivers, infrastructure, climate, land use, and more. Layers were created from various sources and formats. Maps were produced showing potential population, environmental, and transportation risks from flooding in the catchment area, including specific maps for the towns of Godech and Dimitrovgrad.

CREATION OF SPATIAL DATA BASE FOR UPPER NISHAVA CATCHMENT
The preparation of a geographical database for the upper Nishava catchment is a
major task in the creation of a digital terrain model and flood hazard and risk maps.
Design of a GIS database Basin Nishava
GIS platform: a specialized GIS platform has been created for the purposes of this
project, which includes integrated hardware and software components. ArcGIS 10
single user software has been installed and brought into operation.
The life cycle of this database for the project includes two main steps:
1) preliminary analysis and design
2) implementation and operation of the database.
The next stage of the development of the target GIS database includes logical
organization of data, carried out according to the capabilities of the GIS software and
above all the specifications used in its management system databases.
There are a number of additional requirements for the design of a GIS database,
which applies to all stages of its development. They mainly concern the
standardization of data (data format, their accuracy and quality must conform to
certain standards), to control the operations related to the introduction, deleting,
editing and updating data, the need to protect copyright data and information
procedures to prevent unauthorized access to GIS databases, etc.
The data is subjected to the so-called pre-processing procedures. Then proceed to
georeferenced data
The following activities are associated with defining the procedures for converting the
data, which include:
• Data conversion from analog to digital format (digitizing);
• Control changes resulting from the conversion.
The developed database is in Personal geodatabase format, according to the most
common type:

The contents of the database:
Section - Geographical location and boundaries of the catchment includes spatial
information about:
boundaries of catchment area;
river system;
dams and lakes in the catchment area.
Section - Information security includes spatial information about:
• gauging stations and departmental backbone network;
• weather stations and rain from the backbone and the departmental network.
Section - Natural factors include spatial information about:
• Climatic factors - average annual rainfall
• Landscape factors - the geological structure, topography, soil cover,
vegetation cover, protected natural areas /Birds Directive and Habitats
Directive /
Section - Anthropogenic factors include spatial information about:
• Map of the districts and municipalities within Nishava river basin
• Settlements network
• Industrial and commercial sites in the Basin Nishava / Corine 2006 /
• Land use / Corine Corine 2000 and 2006 with excel spreadsheet for areas of
different categories for 2000 and 2006 /;
