4
- High resolution, 3D geo-referenced data. - Tripod based scanner.
5
- High resolution, 3D geo-referenced data. - Tripod based scanner. - Laser emitted and reflected back to the scanner.
6
- High resolution, 3D geo-referenced data. - Tripod based scanner. - Laser emitted and reflected back to the scanner. - Geo-referenced using targets and control points.
7
- High resolution, 3D geo-referenced data. - Tripod based scanner. - Laser emitted and reflected back to the scanner. - Geo-referenced using targets and control points. - XYZ coordinate (Point Cloud) data.

- Upland beach condition surveys. Dunes Dunes Cusps Cusps Vegetation Vegetation - Beach Volume Estimates. - Structure Surveys. Pile Structures Pile Structures Seawalls and Revetments Seawalls and Revetments Groins and Jetties Groins and Jetties
10
- Reduced man power costs. - High speed data collection. - High resolution data. - Easily survey hazardous or inaccessible areas.
11
- High initial start up costs. - No survey beyond water-air interface. - Wet sand can cause errors. - “Shadowing” around objects or pronounced features. - Precise post processing.
18
- Fast capture, high resolution, safe survey method. - Ideal for upland beach surveys. - Cannot capture below water level or wet sand. - Far more detail than traditional RTK GPS surveys.
