Sitemaster Elevations - Screen Shots (14)

Start with a Photograph scanned or from a digital camera, load it into SM Elevations

Lens Correct the photo - this will straighten a known straight or flat surface - Lens Correction takes about 30 seconds.

Calibrate the photo - all you need is two known dimensions x-y axis, this takes about 10 seconds

Trace the features of the building that are shown in the photograph.  Making sure that this is done accurately -
if many windows/features are the same, just do one of them because they can be copied easily in CAD.

 Examples of tracings

When the tracing/measuring is complete, Sitemaster Elevations produces a complete report.

Next Export to CAD or DXF files - we usually use Sitemaster Building as our CAD programme, but any CAD programme
will work well.

Sitemaster Building or your CAD programme receives the rectified data - examples are for illustration purposes
only and are not finished

Finish your Elevational drawings in Sitemaster Building or your CAD programme

 Some Features

Photographic Facade Survey
 
SiteMaster Elevation is an independent add-on for SiteMaster. You can benefit from photogrammetric
procedures by determining detailed measurements from freehand digital photographs or scanned images.
 
SiteMaster Elevation requires only one rectangle with two known side lengths for calibrating an image plan.
The software lets you measure and draw a building in 2D with added height information on floors,
openings etc.

It saves the exact measurement results by
redrawing the image with points, lines, rectangles,
polylines, arcs and circles. SiteMaster Elevation
transfers drawing elements with state-of-the-art
technology to your CAD system, e.g. or SiteMaster
Building. After completing your measurements you can
generate a report list of all measurements and areas.
The results can be exported in excel lists.  

Processing digital photographs of the building's facade
in SiteMaster Elevation allows you to enhance your
project into a full 3D plan with precise exterior views.
 
You can exchange drawing files between SiteMaster Elevation,
SiteMaster (and other solutions) using the .FLX (PowerCAD)
and .DXF file formats.  
 

Note! Precision is approximately 5mm over 8 metres when using a 6megapixal camera. A high resolution and
large image and large calibration plane will give max precision and ability to zoom/pick points.
