Precision Viticulture Australia is licensed to distribute software from Delta Data Systems. PVA use AGIS, a Geographical Information Systems software package, to process high resolution spatial data. ViewPoint is the software package that is distributed to clients for viewing their data. AGIS is the centerpiece of a suite of Precision Ag applications by Delta Data Systems including: Mobile DLog, Pocket Spreader, ViewPoint, and Georef.

ViewPoint is a display and analysis tool. It is intended to be a connection point for CSA, Sales, Grower and GPC.

• Use Spatial Query to model the distribution of events in a field. Example: "Show me the areas in the field that yielded more than 10t/ha."
• Use Image Algebra to build management zone maps or build an application proposal (a recommendation map).
• Use the Map Maker to print color maps of any combination of themes.
• Use inventory tools like Object Properties to build summary statistics for a group of fields, a single field or an area within a field.

Mobile DLog is a mapping system that uses GPS to collect feature coordinates in a GIS digitizing process. This is a process through which georeferenced objects are created and described (attributed) as either point, line or area objects. If you have ever used or seen someone else use a digitizing table to trace map features and add them to a GIS, you will understand that with Pocket DLog, the world is your digitizing table, the area of the landscape on which you are moving is your map and you, with your palm-sized pc and GPS equipment are the digitizer puck.
