Pathfinder Office Software Project is the main way in which data is organized in PFO. A directory where Pathfinder Office looks for data. There are three subdirectories in a project for organizing other kinds of files: base, export and backup. Project is the main way in which data is organized in PFO. A directory where Pathfinder Office looks for data. There are three subdirectories in a project for organizing other kinds of files: base, export and backup. The backup subdirectory contains backup copies of field collected files. When data is downloaded from the datalogger, an extra copy of each file is placed in this subdirectory. The backup subdirectory contains backup copies of field collected files. When data is downloaded from the datalogger, an extra copy of each file is placed in this subdirectory. The base subdirectory is where you should store base station files for differential correction. The base subdirectory is where you should store base station files for differential correction. The export subdirectory is the default target location when GPS files are exported for use in another program.

Whenever you download a new almanac it will overwrite the old almanac, and that is fine. You do not need to save old almanacs.

Data Dictionary - The power of a GIS Data Capture Tool Controls how location information is stored (e.g., how many positions are averaged for a point, logging interval) Controls how location information is stored (e.g., how many positions are averaged for a point, logging interval) Allows us to collect information efficiently (as opposed to writing in a notebook or using field-sheets) Allows us to collect information efficiently (as opposed to writing in a notebook or using field-sheets) Organizes information for GIS / geodatabase (essentially pre-constructs your attribute table) Organizes information for GIS / geodatabase (essentially pre-constructs your attribute table) Enforces consistency (e.g., providing drop-down menus, radio buttons, etc.) Enforces consistency (e.g., providing drop-down menus, radio buttons, etc.)
Data Dictionary - Design Considerations Consider how to address the stated research questions List the target features –points, lines or polygons List the attributes for each feature class and identify their type –menu (fewer errors, easily queried) –free text (flexible, handles the unexpected) –numeric (enumerated, range, derived) –automatic value (e.g. increment, date) Consider including common data fields –e.g. a linking ID number Design to accommodate the unexpected or uncertain
