Quality checks


 

quality-control-yes-14177243_edited.jpg

Quality check and feedback on processes like:

  • Internal BGT-mutations (pre-delivery)

  • Internal BAG-mutations (pre-delivery)

  • Received land survey drawings

FME: Correct Mismatching Coordinate systems 

  • Creating a solution to work with foreign datasets provided in a coordinate reference system (CRS), different from the hardcoded CRS
    the client's software (GisKIT) is working in. This opens up an entire market that competitors cannot access with this software.
    - Researching the limitations of GisKIT.
    - Provided my employer a theoretical solution.
    - Developing the entire software infrastructure in FME necessary for these new processes.
    - Presented the proof of concept. (they said it could not be done, but i proved otherwise)
    - Provided the integration plan.

FME: Automated quality check

  • Automated our quality check that validates if the mapped features are processed and delivered as intended to the client.
    - Spatially check if mapped lines exist in the product: The analysis returns the lines that do not exist within
        a variable distance from the mapped lines in the product while precisely preserving their original topology.
    - Including a validation for the intended attributes of the resulting BGT-objects.
    - It can run locale files only when post-delivery, or even run against the live PostGIS database on the server before delivery.
    - Analysis result can be exported and is compatible with the GisKIT Format for easy adjustment processing.

FME: Pointcloud Thinner

  • Pointcloud thinner based on 'Equal Spacing' between input points, without interpolation or resampling.

FME: Terrain model from Digital elevation model

  • DEM Raster: Extracting a terrain model from a surface model by segmentation.
    - Filtering objects like cars, buildings, light poles, and many other objects from the dataset.

QGGIS Plugin: convert BGT-polygons  to single lines

install-plugin-qgis.webp

  • Agile developed of a QGIS Plugin that converts polygon objects (with common boundaries) in a BGT-extract, to single line objects.
    - Including the user interface, ‘Add result to map’ capability and a conversion progress bar.

FME: Twin City genrator from mapped 2.5D Objects

  • Citymodel Constructor: Builds topologically correct solid objects from a 2,5D (3d-polygon) production database

FME: 3D Product Database updater

  • 3D Product updater: Merges the production databases into a final product, allowing for updates to take place:
    Overlapping features are updated with the newer, object routing is based on several conditions.

FME: Filter unnecessary objects for efficient processing

  • Build a process to prepare RVO-data (agraculture geometry) to be processed into the BGT
    - Saving time during processing by Cutting down 50% of the data that did not need to be processed with an FME analysis.

FME: BOR and BGT Synchronization

  • BOR-BGT data Comparison – comparing the two and provide one with data from the other object registration when one is more recent,
    taking both geometric and adminstrative differences in account.
    - Created 5 different look-up tables because of different terminology and other database joining
    - Processing and preparing the data in a way to make it efficient for a timely goal.

FME: quality check before product delivery

  • BGT-processing QC workbench, comparing the country wide database to our internal twin/mirror and our project files to find accidental unprocessed data or other critical issues
    - designing a logical workflow in process diagrams with lucidchart
    - FME-workbench that connects with our internal mirror database, the countrywide database and our projectfiles to do a comparison analysis and provide information to project leaders and database managers
