1. Adjust Settings
Go to Settings > Edit Units Settings and select the appropriate units for weight to activate Estimation mode. Also, the units for area and length can be set.
Go to Settings > Edit Page Settings and enter the company title and select the required date format.
2. Create Project
Go to Projects > Add New Project and edit default entries as necessary. A unique project number is automatically generated and the date defaults to the current date. If this is saved and is the first project, then it is automatically selected.
3. Select Project
The full range of menu options including Map mode will not be available until a project is selected. Warning messages will be presented if no project has been selected. For instance, if no projects have been defined, a warning will be presented to the user to add one.
Also, when a number of projects are initially available, the user will be prompted to select one.
When a project has been selected, the full set of menu options will be available. The selected project will be identified above the menu bar on the left side. The selected project will appear as bold in the project listing with a View Map link in its left-most column.
4. Defining Areas and Paths
Enter Map mode by either selecting Map from the top menu or by clicking View Map for the selected project in the Projects listing.
On entering Map mode, any previously defined Areas and Paths will automatically be loaded for the selected project. To define an Area, enter a sequence of points by left-clicking and finish by re-picking the first point. An Area will be created and a label displayed detailing the area and perimeter values.
To define a Path, enter a sequence of points by left-clicking and finish by picking the End Path button in the top right corner of the map. A Path will be created and a label displayed detailing the length value. Note that above the map are tick boxes for toggling the display of Areas, Paths and their respective labels.
To switch off the display of individual labels, click on the x button in the top right corner of the label. Individual labels for Areas and Paths can be switchd on. For Paths this can be done by picking the line in between points. For areas this can be done by picking the interior of an area. To delete an Area or a Path, click on the Delete button for the appropriate label. On Exit Map, any changes to Paths and Areas are automatically saved.
5. Create Weight Parameters
There are three types of weight parameters which can be defined. These are area-based, length-based and fixed. The one that is perhaps the most important is area-based. For many applications, this can be interpreted as coverage. The parameter has the units of weight per unit area. When it is multiplied by an area value it will produce the total weight required to cover a user-defined area with a commodity such as fertilizer. Go to Weight Params > Add New Weight Param and enter a description and a value for the parameter. Note that the area units for the parameter can be different from the geographical area. Conversion factors will be automatically applied. Weight parameters are stored for each user and are available to all Projects.
6. Adding Estimates to Project
To create an estimate, go to Estimates > Add Area Estimate. This enables a geographical area to be linked to an estimate parameter. Selection boxes are presented to enable the area and parameter to be selected. The resultant area weight is also displayed and will change automatically if different area and parameter pairs are selected
7. Viewing an Estimate
Any number of individual estimates can be added to form a project estimate. For instance, if a second area is added, then the complete estimate in the form of the total Project Estimate can be viewed by going to Estimates > List Project Estimate. The total project weight estimate is displayed
8. Printer Output
There are two types of printer output available. If Estimates > List Project Estimates is selected, the Print menu option is available. This generates a full list of individual weights
In Map mode, the Print menu option is also available. This generates a full list of weight estimates along with a map representation that depicts the Areas and Paths that have been defined as part of the project.
