Digitizing is the process by which coordinates from a map, image, or other sources of data are converted into a digital format in a GIS. This process becomes necessary when available data is gathered in formats that cannot be integrated with other GIS data.
Digitizing is the process of converting geographic features on a paper map into digital format. The x, y coordinates of point, line and polygon features are recorded and stored as the spatial data. The feature attributes are also recorded during the digitizing process. It is the most common and labor intensive method to create a spatial database. The method is used especially when existing maps are available as the source of data. Coordinates of point features, line features and polygon features are recorded by manually pointing or tracing, using a digitizer table and cursor. The cursor position is accurately measured, by the device in order to generate the coordinate data in digital form. Although digitizing is substituted by scanning, digitizing tablets are still used to convert existing maps and drawings into GIS.
Georeferencing means that the internal coordinate system of a map or aerial photo image can be related to a ground system of geographic coordinates. Coordinate transforms are typically stored within the image file though there are many possible mechanisms to store georeferencing information. The most visible effect of georeferencing is that GIS software can show ground coordinates such as latitude/longitude and also measure ground distances and areas.
In other words, Georeferencing means to associate something with locations in physical space. The term is commonly used in the geographic information systems field to describe the process of associating a physical map or raster image of a map with spatial locations. Georeferencing may be applied to any kind of object or structure that can be related to a geographical location, such as points of interest, roads, places, bridges, or buildings. Geographic locations are most commonly represented using a coordinate reference system, which in turn can be related to a geodetic reference system such as WGS-84.
Orthorectification is the process of removing the effects of image perspective tilt and relief terrain effects for the purpose of creating a planimetrically correct image. The resultant orthorectification has a constant scale wherein features are represented in their 'true' positions. Our company provides scanning, referencing and orthorectification or historical maps and imagery.

Golf courses are often criticized for adversely affecting the environment, but a well-managed, properly irrigated golf course can benefit the environment and the surrounding community in a variety of ways.
Best Management Practices (BMPs) and new technologies are available that offer course management staff an opportunity to reduce wastes while saving money and improving efficiency.
By practicing waste minimization you can improve your bottom line while keeping a course evenly green and well managed. Using Turf Image Products will help..
During application, using Turf Image products help pinpoint geographically what types of materials need to be used and how much of each chemical mix should be applied. By saving water and chemicals Turf Image products help cut a few strokes of the cost of course management.
