Use Tree Sampling
Check box to indicate that tree sampling may be used to determine if a tree should be measured rather than tallied. When enabled, MobileMap will alert cruiser when recording the nth tree so cruiser knows to measure DBH, height, etc. Complete settings below to define the sampling type field and values representing the different supported sampling types"
Stand-Level Sample Type Field
Name of field in the Stands table that stores the type of sampling (if any) should be used for a given plot. Default field name is 'Sample_Type'. MobileMap expects that this field will use a coded value domain with the following values for supporting sampling types: BB = Big BAF, STR = Sample Tree Ratio, FTN = First Tree North, PCM = Point Count or Measure, None = no sampling."
Plot-Level Sample Type Field
Name of field in the Plots table that stores the type of sampling (if any) should be used for a given plot. For 'Point Count Measure' approach, sample type at the Stand level will be used to set plots to Count or Measure. Default field name is 'Sample_Type'. MobileMap expects that this field will use a coded value domain with the following values for supporting sampling types: BB = Big BAF, STR = Sample Tree Ratio, FTN = First Tree North, PCMC = PCM Count, PCMM = PCM Measure, Tally = all trees tallied (same as PCMC, all trees counted and not measured) None = no sampling (same as PCMM, all trees measured)."
Tree-Level Sample Type Field Name and Values
Name of field in the Trees table (field name should be different than plot-level sample type field) that stores whether tree is a Measure tree or a Tally tree, and the values representing 'measure' and 'tally'. Use colons to separate 3 components. Typically the values will come from a coded value domain assigned to this field. Default field name is 'Sample' and values are 'M' and 'T' (e.g., 'Sample:M:T',without quotes). Note, cannot use non-nullable fields for fields like DHB or Height, since tally trees do not require these measurements (Species and Tally or Count can be non-nullable).

Enable Calculation of Stand Stand Summary
Check box to enable calculation of stand summaries including BA, TPA and QMD
Check box to enable calculation of plot summaries including BA, TPA
Minimum DBH for average tree per plot calculation
Minimum DBH for determining if a tree should be included in the average tree per plot calculation in stand summary. Default is zero, increasing this value can prevent small trees from having strong impact on average trees per plot calculation."
Confidence Level
Confidence level as a whole number percent. Used when calculating statistics like confidence interval and target sample size. Supported values include 68%, 90%, 95%, 99%. Default is 95%.
Allowable Error Value(s)
Allowable error used when calculating target sample size. Supports more than one value. Recorded as whole number percent using a comma separated list (e.g., 20,10). When multiple values are used, the stand summary will report multiple target sample sizes, one for each allowable error value.

Nested Plots
Check box to indicate that a nested plot design is used. Nested plots are small fixed radius plots used to measure smaller trees. Use the fields below to indicate the DBH cutoff and area of the nested plot"
BAF Limiting DBH
Minimum DBH of trees measured on variable radius plots when nested plot design used. This will ensure that trees are assigned to their correct plot/subplot during calculations. This is equivalent to the ‘DBH Breakpoint’ used FVS
Nested Plot Area
Area of nested plot in fraction of an acre. For a 1/200th acre plot (radius 8.33 ft) use '200' (no quotes)"
Confidence Level
Confidence level as a whole number percent. Used when calculating statistics like confidence interval and target sample size. Supported values include 68%, 90%, 95%, 99%. Default is 95%.
Allowable Error Value(s)
Allowable error used when calculating target sample size. Supports more than one value. Recorded as whole number percent using a comma separated list (e.g., 20,10). When multiple values are used, the stand summary will report multiple target sample sizes, one for each allowable error value.
