Importing data

Once you have chosen a data set to import, BoundarySeer prompts you to specify the name, coordinate system, and the data delimiter in the file type.

Data name

You can name the data set, or BoundarySeer will use the file name (without the file extension) as the default.

Coordinate system

For vector data only, choose the coordinate system of your data. BoundarySeer can import data in planar coordinates (includes but does not differentiate between many projections) and geographic coordinates (latitude-longitude). Because BoundarySeer works in planar coordinates, it transforms data in geographic coordinates to UTM for analysis. All data sets in one project need to be imported in the same projection, otherwise they will not register properly for use in BoundarySeer.

BoundarySeer treats all raster data as a planar projection.

Data delimiter

For text data, you need to choose the data delimiter (whether it is delimited by tabs, spaces, or any white space, which can also include carriage returns).

Also, BoundarySeer needs to know whether to lump successive delimiters (e.g. a series of tabs) or to interpret them as delimiting missing values. If you tell it not to lump delimiters, it places the missing value code in the empty cells.

Missing value code

If you have or want missing values in your data set identified with a particular code, enter that code here. BoundarySeer will then interpret the code as missing data. Locations with missing values will not be used in the calculation of gradients or dissimilarity metrics for boundary delineation. Currently, decimal values and text strings cannot be used as missing value codes.
