Image Rectification and Mono-plotting Software

We write excellent Windows software for mapping from aerial photographs. Clients will typically use our products to import rectified image or vector data to their Geographic Information System (GIS)

Image rectification is the conversion of a digital version of an aerial photograph into an image which will fit the map. Distortions caused by terrain height, camera tilts and camera lens distortions will all be removed. You must supply a Digital Elevation Model (DEM) corresponding to the image being rectified. Our two image rectification products are:

ORTHO32 - our most popular product where you supply the DEM,
ORTHO12D - with the DEM coming from the 12d Model engineering and design software.

Mono-plotting is tracing linework from a single unrectified aerial image and having the software convert your linework into fully corrected XYZ data. You must supply a DEM covering the aerial image you are tracing from. Our mono-plotting product is SPSCREEN (for tracing data on-screen from a scanned or original digital image).

Prices, Support and Licensing - we charge once only for a single licence. For that price you get unlimited email support and regular free software upgrades which are available on this web site. We notify you when an upgraded version is available for download. Software is licensed to run on a single PC and is tied into a PC by an unlock code. If you have paid for a system we ask no questions when you request a new unlock code, for example when you upgrade to a faster PC.

Digital Terrain Model (DTM or DEM) - if you must supply a DTM we require it to be in an ASCII format. Conversion utilities are built into most of our products to convert from USGS DEM, ESRI Shapefile and DXF data sources.

Virus Note - we use Vet in order to scan for viruses before placing any files on our download server.
