GIS - Updating the existing database of residential buildings

Project Details

The project involved verifying the accuracy of existing buildings in the database and adding new buildings that were not previously included. This was accomplished using orthophotos, Street View, topographic maps, and additional supporting materials. The geometry of the buildings was corrected, and relevant information such as building type, purpose, and number of floors was added to the attribute table.

Client: Environmental protection company, specializing in air emission measurements, wastewater analysis, waste management, and environmental noise assessment.

Database Updating

Solution: Verification and update of the building database, including geometry corrections and attribute updates using orthophotos, Street View, and topographic maps.

Location: Poland

Technology and Software: The project utilized QGIS as the primary tool for the verification and updating of the building database.

People: The GIS-Point team comprised 8 GIS specialists and a quality controller, who collaborated closely throughout the project.

Process & Challenges

Process: The process began with the collection and analysis of orthophotos, Street View images, and topographic maps to gain a comprehensive understanding of the current state of the building database. Using QGIS, the team verified the accuracy of existing buildings and identified new ones that had not been previously recorded. The geometries of the buildings were corrected where necessary, ensuring that their spatial representation was precise. The team also updated the attributes of the buildings, including details such as type, purpose, and number of floors. In addition, topology checks were performed to ensure that there were no overlaps, gaps, or other inconsistencies in the spatial data. Finally, the attribute database was thoroughly verified and updated to reflect the latest information, ensuring data consistency and reliability. The entire process was carried out meticulously, covering an area of 500+ km².

Challenges: The highly specialized nature of the maps required meticulous attention to specific mapping characteristics, particularly in ensuring the accuracy of building geometries and attributes.

Result

The existing building database was successfully updated with accurate and comprehensive information, reflecting current structures within the covered area.

Navigating Our Impressive GIS Portfolio

Automatic tree recognition from orthophotos

Location:

Germany

Automatic Tree Recognition with ArcGIS Pro is a project that aims to develop and implement an algorithm for automatic recognition of tree species based on remote sensing data.
Digitizing utility service connections

Location:

Canada

The project encompasses the digitization of utility service connections, specifically for water, sewer, and storm services, spanning across 12,706 properties (parcels) within the City.
Geospatial Analysis and Image Processing

Location:

Poland

Editing the automatically generated database of motorways, bridges and roads.
Updating the BDOT topographic database at a scale of 1:10000

Location:

Poland

Using an orthophotomap, we check the relevance of the existing topographic objects in the database, as well as create new ones (which are not in the existing database).
Fulfillment of government orders to create and update databases

Location:

Poland

The databases are created and updated by vectorizing existing raster data (topographic maps), orthophotomaps and processing geodetic files and land documentation (by coordinates and sketches).
