Custom imports: multiple GRID files

The GRID format is a proprietary ESRI^® format for raster data that contains only one variable. You may combine several GRID files into one BoundarySeer data set. To do so, each file must contain numeric data, have the same header, and cover the same spatial coordinates. At this time, categorical GRID files cannot be imported and combined into one data set.

When creating a new project in BoundarySeer, you cannot import multiple GRID files. Cancel out of the "Quick Start" dialog if you do not want any other data sets in your project.

1. To import multiple GRID files, choose "Import" and then "Custom: multiple ARC/INFO^® GRID" from the "Data" menu.

2. After you choose to import multiple GRID files, the "Import Raster Data" dialog will appear. Choose the file type. Next, select the files to import using the shift or control keys to select multiple files. Hit "Import."

3. On the "Import Data" dialog"

   1. Choose a data set name (BoundarySeer chooses a name of one of the files as the default).

   2. Verify the coordinate system.

   3. As GRID files are tab-delimited, the data delimiter section of the dialog will be grayed out.

   4. If a missing value code is specified in the header, then the missing value section of the dialog will be blank. If not, choose a missing value code.

   5. Hit "Next"

4. Choose whether to view the data in a map (either a new or existing map).
