Portfolio

A complex project including the following: 1. Spatial database design for Water Utility System using PostgreSQL. 2 Aerial imagery processing with GDAL. 3. input forms created for QGIS using python and Qt designer. 4. Rendering raster and vector layers with Geoserver. 5. Web responsive design of a Water Utility System webpage for Samsung Note 3 (Full HD display) using Leaflet. All mobile devices accessing the main page are redirected towards the mobile friendly version.

Bicycle tour map

Cartographic design for a 1.9 m diameter globe.
The globe has the following particularities:
1. Mecca is placed on the top of the globe (in the position of the North Pole);
2. grid lines are pointing to Mecca;
3. all countries/ major cities are oriented towards Mecca with curved labels.

Qibla globe

The program reads the coordinates of each polygon node from a text file and constructs the polygons based on a another text file defining the connections between these nodes (topological relationship). After plotting the polygons the user can click in them. The number and the area of the clicked polygon is displayed on the console. The user can decide whether he continues to click in the polygons or closes the program.

The requirement was to use basic mathematical algorithms instead of Matlab's advanced ones. As an example the area was calculated using a formula with the coordinates of the vertices, instead of a simple Matlab function.

Area calculation of polygons

The program reads the terrain model from a text file and calculates the hilllshade based on user defined angles of the sun.

Hillshade calculation of terrain in Matlab

A MATLAB program created to calculate the seismic response of a simple industrial building. The graphic user interface is designed to allow the user to input geometric and material properties, to define loads and to choose an earthquake from a list of recorded historical data.

Volume calculations with ArcGIS

Techical University of Cluj-Napoca

This work is demonstrating the applicability of Geographical Information Systems (GIS) in engineering works, such as calculating the volume of material in embankments, landslides, quarries and amount of water in lakes. In the project are analyzed different methods for calculating volumes using ArcGIS 10. Besides the available software tools, an own calculation method is tried.
