Tip
Importing yield data from external models
Growth and yield data are a essential input to Patchworks: without these data wood supply analysis simply could not be done. Yield curves often come from complex external models (FVS, MIST, VDYP or GYPSY for example) and differing output formats raise compatibility issues. This note describes an easy and flexible way to import a variety of yield curve data formats in to the Patchworks model.

Feature
Treatment packages
Treatment 'packages' are a capability to implement a combination of treatments as a single scheduling action. This type of scheduling is appropriate when a known sequence of actions follow from an initial action, such as with the stages of shelterwood silviculture progressing after the first action has been initiated.

Tip
Cell formatting
Patchworks makes a best effort to effectively format the data values that are shown in reports. The basic method is to provide a level of precision appropriate for the magnitude of the numbers involved. But in some cases a different format can make a better data representation, and this is where custom formats come in handy.

Feature
ReportWriter progress alert
When you click on a report title the Patchworks model starts up a background thread to generate the results. If time consuming calculations are required then the report wont show up right away, and nothing would seem to happen. This new feature presents an on-screen alert indicating that the reportwriter is busy working.

Feature
Pivot table data exploration tool
Most people are familiar with pivot tables as a quick, intuitive and flexible way to summarize and subdivide data. This easy yet powerful capability is available in Patchworks for summarizing data tables and producing reports.

Tip
Color ramps
Color is an extremely important component of the visual presentation of map data: the choice of colors will affect viewers perception and comprehension of the message. Patchworks provides a very easy to use mechanism to review and apply a range of attractive color sets.

Feature
Export to CBM-CFS3
CBM-CFS3 is carbon budget model that is being used more often by Patchworks clients. Patchworks outputs contain all of the information that is required by CBM-CFS3, but in the past it has taken a bit of manipulation to get these data in to the correct format. The addition of a CBM-CFS3 export wizard makes this process a lot easier.

Feature
Raster data display
Raster technology provides a simple and powerful way to model spatial relationships across and between surfaces. Some operations that are slow and problematic with vector methods run efficiently in raster mode, and raster modeling is often the method of choice for habitat modelers. Patchworks has a capability to work with raster data sets and provides some great tools for viewing, printing and summarizing raster data sets.

Installation
A note to Patchworks customers regarding Java
Patchworks is a Java application, and you must install a java runtime. In 2019 Oracle changed the licensing conditions for Java. This note describes what these changes mean and explains your options for installing Java.
