Creating Stand Maps, Generating Plot Maps, and Upload/Download Plot Points to GPS
Create Stand Map with Topo Base Map Open ArcMap In ArcMap, select File → Add Data.. → Select Layers –Example Topo Map (tif file): l47.tif Stand Boundary (shapefile): FS_Cat_Creek.shp
1)View can be changed using “zoom in”, “zoom out” functions on tool bar. 2)Characteristics of stand boundary (i.e., fill and line color) can be changed by clicking on the symbol in the layers window.
Generating Systematic Plot Grids
Calculating Distance between Points for Systematic Sampling
Arctoolbox → Data Management Tools → Feature Class → Create Fishnet Generate Inventory Plot Grids
Input new feature name Constrain to stand boundary Input number plot spacing Input ‘0’ to autofill into stand polygon Generate Inventory Plot Grids
Make sure necessary amount of points are within layer. If too few points lower spacing. If too many points randomly select points from existing points Generate Inventory Plot Grids
Clip Inventory Plot Grid
Clipped Inventory Plot Grid
Random Selection of Plots from Systematic Plot Grids
Arctoolbox → Data Management Tools → Feature Class → Create Random Points Generate/Select Random Points
Input new feature name Constrain to point grid Input number of points to be selected Randomly Sample Inventory Plot Grid
