Photogrammetry Services and Interactive Digital Maps

Service Details

1. Photogrammetry Services

a. Planning and Preparation:

• Defining areas of interest for aerial data collection.
• Obtaining necessary permits for drone flights in designated areas.

b. Aerial Data Collection:

• Using a drone equipped with high-resolution cameras to cover the entire territory of the administrative unit.
• Conducting systematic flights to capture two-dimensional and three-dimensional images of the terrain.

c. Data Processing:

• Converting aerial images into a high-resolution orthophoto map.
• Generating a digital terrain model (DTM) and a digital surface model (DSM).
• Verifying and validating the accuracy of the collected data.

2. Measurement and Inventory of Surfaces

a. Identification of Buildings and Land:

• Measuring the footprint of existing buildings using remote sensing methods.
• Identifying and delineating land within the administrative unit’s territory.

b. Creating Databases:

• Converting measured data into digital format (SHP file).
• Creating a geospatial database (interactive digital map) that includes all identified buildings and land.

c. Verification and Validation of Data:

• Comparing measured data with existing information in the agricultural register and the tax and duties department.
• Correcting any discrepancies and updating databases.

3. Collection and Analysis of Fiscal Data

a. Data Collection:

• Obtaining updated data from the Agricultural Register and the Tax and Duties Department.
• Accessing and extracting relevant information about real estate properties and their fiscal status.

b. Data Analysis:

• Comparing data collected from the agricultural register and the tax and duties department with field-measured data.
• Identifying discrepancies and undervalued or non-evaluated properties.
• Creating detailed reports that include all identified properties and their fiscal status.

4. Orthophoto and Lidar

a. Orthophoto:

• Conducting drone flights and processing the orthophoto in interactive digital format (ECW or TIFF).

b. Lidar:

• Performing mobile mapping measurements (point cloud + street view) and processing the data.

5. RENNS

• Integrating RENNS data into the interactive digital map.

6. Data Processing

Identifying building footprints with specialized software and importing data into an Interactive Digital Map

7. Interactive Digital Map

• Creating and managing layers for all component localities of the administrative unit, including cadastral land and the orthophoto map.

8. Reports

• Creating detailed reports for each household, including comparisons between real data and the existing municipal data.

9. Training

• Training municipal staff in the use of databases and management of interactive digital maps.

10. Documentation Preparation for Fiscal Inspection

a. Creating the Interactive Digital Map:

• Integrating collected data into a detailed interactive digital map with layers for buildings and land.

b. Developing Fiscal Reports:

• Preparing reports and documentation necessary for fiscal inspection, including recommendations for updating fiscal evaluations.

c. Data Integration and Staff Training:

• Final handover of the interactive digital map and all analyzed data, along with training for effective use by the staff.

Technical Characteristics of the Interactive Digital Map

• Specialized interactive digital map in vector format, prepared in the Stereographic 1970 (Stereo 70) projection system.
• Detail representation accuracy of +/- 5 cm.
• Each vectorized data will be associated with an attribute table containing textual and numerical information.
