Project Details

Preparation of a topographic drawing at a scale of 1:500 based on lidar data and orthophotos. The area covered was 167.55 hectares. The vectorisation included the creation of horizontal and elevation marks, as well as a detailed display of the terrain, including roads, ditches, rivers and other elements.

Client:  The market leader in Latvia in providing geodetic and cartographic services.

Sector:

  • Geodesy and cartography
  • Landscape design
  • Engineering
  • LIDAR Data Processing Service


Sub Sector:

  • Civil engineering
  • Engineering networks
  • Road construction

Services:

  • Georeferencing
  • Creating a digital surface model
  • Create an orthophoto plan
  • Vectorisation of linear objects
  • Create a topographic map
  • Add attribute information

Solution:

  • Strict compliance with the terms of reference
  • Clear work schedule
  • Regular reporting

Location:  Latvia

Technology and Software:

To complete the project, the company used modern technologies and software to ensure a high level of accuracy and efficiency in data processing.

AutoCAD Civil 3D: The main tool for data processing and mapping. This software allows automating the design of infrastructure facilities, which significantly reduces the time for project development.

MicroStation CONNECT: Used for design and modelling. This software allows you to create detailed engineering models and drawings, while providing integration with other systems and tools.

The use of these technologies enabled the team to process large amounts of data quickly and efficiently, and to ensure high quality and accuracy of the final results. Interaction between the various applications has helped to optimise processes and reduce manual labour, which in turn has contributed to reducing risks and increasing productivity.

People:
The GisPoint team involved in the project consisted of four cartographers and a project manager. We worked on a 1:500 scale topographic drawing partner company from  Latvia, using AutoCAD Civil 3D software, the team processed LIDAR data and orthophoto images, created a 2D vector map based on laser scanning and complied with Latvian legislation.

Process & Challenges

Process:
Data analysis: Detailed analysis of lidar data and orthophotos to identify terrain features, infrastructure and other elements to be vectorised.

Terrain vectorisation:

Horizontals: Create horizontals in 0.5 m increments for detailed mapping of landforms.

Elevations: Placement of elevation marks in 20 m increments on roads and at characteristic terrain points (highest and lowest points). In other areas (forest, meadow, etc.), elevations were placed in 15 m increments.

Linear objects: Vectorisation of ditches, rivers, ravines and other linear terrain features.

Vectorisation of infrastructure objects: Vectorisation of roads, buildings, green spaces and other infrastructure objects based on orthophoto and lidar data.

Quality control: Perform detailed visual and attribute quality control of vectorisation to identify and correct errors.

 

Challenges:
Data volume: Large amounts of LiDAR data requiring powerful hardware and efficient processing algorithms.

Detail: High requirements for topographic map detail, requiring careful data analysis and manual revision.

Regulatory framework: The need to comply with Latvian legislation on the creation of topographic maps.

Result

GisPoint successfully completed a project to create detailed topographic maps at a scale of 1:500 with a total area of 185.55 hectares. The resulting maps comply with Latvian legislation and can be used for: Territory Planning: Development of urban planning documentation, infrastructure design. Engineering Calculations: Design of roads, bridges, engineering networks. Cadastre: Registration of land plots, determination of property boundaries. Other Purposes: Scientific research, monitoring changes in the terrain, etc.
