🗺️ Open SiteMarker See how it worksSiteMarker combines professional mapping tools with an intuitive interface designed for field workers and project managers.
Access a comprehensive library of standardized road signs and construction markers. Drag and drop icons directly onto the map to create accurate signaling plans compliant with Belgian and European standards.
Draw custom zones, access routes, and exclusion areas with our brush tool. Adjust line thickness and color to differentiate between pedestrian zones, vehicle corridors, and restricted areas.
Instantly measure distances between any two points on the map. Essential for calculating safety perimeters, estimating material quantities, or verifying compliance with regulatory setback requirements.
Export your annotated map as a high-resolution PNG image ready for permits, client presentations, or safety briefings. Save your work as a JSON project file to continue editing later.
Add clear text labels to identify streets, zones, equipment positions, or safety instructions. Labels are fully editable and can be repositioned at any time.
Upload your own SVG icons to extend the library with company-specific markers, custom signage, or specialized equipment symbols relevant to your industry or region.
SiteMarker is designed to be used immediately, without any training or software installation.
Type your worksite address in the search bar. SiteMarker will navigate to the exact location on OpenStreetMap.
Drag road signs, safety cones, and equipment icons from the toolbar directly onto the map at the correct positions.
Use the brush tool to define work areas, detour routes, or pedestrian zones. Adjust colors to distinguish different areas.
Download the map as a PNG for immediate use in documents, emails, or permit applications. Save as JSON to edit later.
Create detailed traffic management plans for road maintenance and construction projects. Mark temporary traffic lights, lane diversions, speed restrictions, and worker safety zones to meet regulatory requirements.
Communicate site access plans to subcontractors and delivery drivers. Mark crane swing zones, material storage areas, and site entrances to improve coordination and reduce accidents on complex construction sites.
Plan temporary road closures, parking areas, and pedestrian flows for public events, festivals, and sporting competitions. Share clear visual plans with local authorities and security teams.
Document public works schedules, plan maintenance interventions, and communicate roadwork impacts to residents. Create clear visual records of infrastructure changes for administrative archives.
Map incident perimeters, access routes for emergency vehicles, and evacuation zones. Create rapid situational plans during incidents to coordinate response teams efficiently.
Plan last-mile delivery routes, mark loading zones, and identify access restrictions in urban areas. Optimize vehicle movements within industrial sites and distribution centers.
