Project Details
Client: Environmental consultancy, specializing in marine and offshore projects.
Sector: Marine Geospatial Analysis
Sub Sector: Seabed Mapping
Services:
- GIS Consultants
- Topology Checks
- Error Correction
Solution: Topological Integrity Assurance for Seabed Maps
Location: Spain
Technology and Software: ArcGIS was utilized to perform the topology checks and corrections, ensuring a high level of precision and efficiency in the process.
People: A dedicated team of GIS specialists from GIS-Point worked on this project, including quality controllers and project managers, to ensure the successful completion of the topology validation tasks.
Process & Challenges
Process:
The process began with an in-depth analysis of the seabed mapping data, focusing on detecting and correcting topological errors. We identified the most efficient methods to resolve these issues, ensuring that the solution would minimize time without compromising on accuracy. The standard checks included ensuring that objects do not overlap (“Must Not Overlap”), eliminating any gaps between polygons (“Must Not Have Gaps”), and verifying that polygons did not exceed a specified maximum size (e.g., “Polygons must have a maximum size of 1 square meter”). These steps were executed meticulously using the capabilities of ArcGIS software
Challenges:
The primary challenge was managing the specialized nature of the seabed maps, which required particular attention to the unique characteristics of marine cartography. These high-precision maps demanded a careful approach to topological corrections, ensuring that every adjustment was in line with the strict mapping standards. Additionally, the large volumes of data needed to be processed efficiently to maintain accuracy.
