Sample_Type
This field should be a text field in both the Plot and Stand feature layers that uses a Coded Value Domain that lists all double sampling methods that are supported, and an option for 'None'. The list of accepted values are:
BB = Big BAF
STR = Sample Tree Ratio
FTN = First Tree North,
PCM = Point Count or Measure
None = no sampling
Big_BAF
If the Big BAF method is supported, this field should be a text field that uses a Coded Value Domain that lists all of the BAF values that are appropriate for Big BAF. Allowed values should follow the same convention
PCM_Ratio
If Point Count Measure method is supported, this field should be a text field that uses a Coded Value Domain that lists all of the allowed ratios in the format of '1:2', '1:3', '1:4', etc.
STR_Ratios
if Sample Tree Ratios are supported, this field should be a text field that will store a comma separated list of ratios (e.g., 'DF:S:5,DF:P:10,GF:XX:2,XX:XX:3')
Tally_Measure
This field should be a text field in the Tree feature table that uses a Coded Value Domain with the values 'M' for measure and 'T' for tally. MobileMap will update this field automatically when it can determine if a tree should be measured or tallied. Automatical determiniation Automatic determination of T or M will be possible for PCM, FTN and STR, but not for Big BAF

Settings > Tree Sampling> General
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_Type: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).
Settings > Tree Sampling> Sample Group Methods - FTN, STR
Tree Sample Group Attribute Fields - Comma separated list of up to 2 fields in the tree table that define a sample group for First Tree North (FTN) and sample tree ratio (STR) subsampling. Default value is 'Species,Product' (without quotes).
Note: We strongly recommended that you do NOT populate all of these fields via Configurable Defaults (Configurable Defaults). Using Configurable Defaults on STR sample group definition fields could result in new trees being added to the tree list that are automatically assigned to Measure or Tally status. Changing the fields after that assessment will NOT update the Measure or Tally status and thus unexpected results could occur.
Sample Tree Ratios Field - Field in the Stand and/or Plot table that stores the sample tree ratios. Default value is 'Sample_Tree_Ratios' (without quotes).
Default Sample Tree Ratios - This setting can be used to pre-populate the Sample Tree Ratio editor when setting Sample Tree Ratios on a newly created Stand in MobileMap. To use this setting, enter a comma separated list of sample tree ratio entries. For each sample tree ratio, enter the grouping fields and the ratio, separated by colons. For default, use 'XX' for text or '0' for integer fields. E.g., 'DF:S:5,DF:P:10,GF:XX:2,XX:XX:3' (without quotes) indicates that every 5th Douglas fir sawtimber tree, every 10th Doug fir Pulp tree, every second Grand fir (any product), and every third tree for all other species and products should be measured and the rest of the trees should be tallied by species or species + product (according to the Sample Tree Ratio Fields above). Each sample tree ratio included here will be included when populating a new sample tree ratio entry using the Sample Tree Ratio editing tool. The default Sample Tree Ratios have been populated in the tool, they can be modified or augmented within that tool to achieve the specific Sample Tree Ratios desired for the current Stand.
Settings > Tree Sampling> Big BAF
Tree-Level BAF Field for Big BAF method - Name of field in the Trees table that stores the type of BAF that includes a given tree. Default field name is 'BAF_Type'. MobileMap expects that this field will use a coded value domain with the following values BAF types: B = Big BAF, S = Small BAF.
