MUPOLYGON Summary by Project

This report summarizes the zonal statistics for an MUPOLYGON layer within a file geodatabase. The spatial variables summarized include: elevation, slope, aspect, relief, preciptation, temperature, frost free period, and landcover. The report assumes the spatial data follows the proper folder hierachy and naming conventions (e.g. C:/geodata/project_data/11IND).

The spatial extent for the summary is derived from an MUPOLYGON layer contained in a file geodatabase. To select the desired map units for analysis specify the NASIS projectname. The projectname will be used to query NASIS via a web report and the nationalmusym linked to the project will be identified and used to subset the MUPOLYGON layer.

Report Parameters

• NASIS Project Name (e.g. "EVAL - MLRA 111D - Fincastle silt loam, Southern Ohio Till Plain, 2 to 4 percent slopes")
• File Geodatabase Name (e.g. "RTSD_MLRA_11-IND_FY18.gdb")
• Geodata Project Data File Path (e.g. "M:/geodata/project_data/")
• MLRA Soil Survey Office Symbol (e.g. "11-IND")

Example

# load the soilReports package
library(soilReports)
library(rmarkdown)

# run the report manually
## copy to your workspace2 folder

copyReport(reportName = "region11/mupolygon_summary_by_project", outputDir = "C:/workspace2/mupolygon_summary")

## Open the "report.Rmd" file from "C:/workspace2/mupolygon_summary" in RStudio, and hit the "Knit HTML" drop down arrow and select "Knit with Paramters..." menu item. Modify the parameters accordingly. 


## run the report via commandline
reports = listReports()
reports = subset(reports, name == "region11/mupolygon_summary_by_project")
