SVG & SLD Symbology

Spatial Plan Symbology Library and Automated Style File Generation

A digital plan symbology infrastructure that brings the plan notations of Turkey's Spatial Plans Construction Regulation into the digital domain, standardizing GIS workflows with an SVG symbol library, SLD style files and institution-specific format generation.

CHALLENGE

Plan notation is not just a visual preference; it is critical for regulatory compliance, cross-institution standardization and correct interpretation of plans. Symbols prepared manually, interpreted differently by teams, or delivered in formats unfit for GIS create problems.

The result: inconsistent notation, regulatory compliance risk, time lost to manual symbol production, incompatibility across GIS software and a lack of standards in inter-institution data sharing.

SOLUTION

The infrastructure turns the regulation's plan notations into a digital symbology library. Symbols are produced as SVG, matched with SLD style files for GIS, and integrated into plan production workflows.

Institutions no longer recreate symbols per project; they quickly access regulation-compliant notations from a standard library and keep plan production consistent.

System Capabilities
01SVG Symbology Library
Regulation-compliant plan notations are digitalized as SVG: scalable, high-resolution and adaptable across planning environments. They are classified by Environmental, Master and Implementation Zoning Plan types and remain extensible.
02SLD Style File Generation
SLD style files are produced for direct use in GIS software. Symbology is matched to geographic data layers; manual style assignment drops, layer-level notation standards are preserved and map outputs stay consistent.
03Continuously Updated Regulation Library
Not a one-off deliverable but a living library. When the regulation gains a new notation, symbology or style, the corresponding SVG/SLD assets are produced and added to the library in short order.
04Institution-Specific Formats & Integration
Beyond standard SVG/SLD, custom style files, layer-based symbology sets and file structures compatible with the existing GIS infrastructure are produced. The solution becomes a flexible service embedded in the institution's digital planning processes.
KEY BENEFITS
Strengthens regulatory compliance
Enables standard, consistent plan production
Cuts the manual symbol-production burden
Offers direct use in GIS software
Adapts quickly to new notations

IN BRIEF

A plan symbology infrastructure that digitalizes the notations of the Spatial Plans Construction Regulation as an SVG symbol library and SLD style files — regulation-compliant, standardized and GIS-ready for municipalities and public institutions.
