Export Layer Data as ESRI Shape Files
Select layers of data can be exported in the ESRI (Environmental Systems
Research Institute, Inc.) shape file format. This format differs from the AEA
shape file format (refer to page 245), which can only export yield data.
ESRI Shape files are a great choice, for example, if you are wanting to
exchange information with a cooperator who does not have JDOffice, but
whose software requires shape files. By exporting your data as an ESRI shape
file, you can make it possible for others to view your field maps and the values
associated with each point of data.
There will be three files for every layer exported: the *.dbf contains the field
values and can be opened in a spreadsheet application (such as Microsoft
Excel); the *.shx is an internal index; and the *.shp can be opened in any
application that supports the ESRI shape file format. All three files must be kept
together.
There is an fourth additional file - the *.jda. This file serves as a legend (unit of
measure) for all the numerical values that are found in the .dbf file. For each
column of figures in the .dbf, there will be a corresponding attribute column
name line in the .jda.
The exported layers will be saved in a folder that
is named after the farm and field:
FMnnnnnFLmmmmm. FM indicates farm,
followed by the 5 digit farm number; FL indicates
field, followed by the 5 digit field number. The
individual layers will automatically be named
after the field name in the Layers Chooser.
For a sample of the exported .jda format, refer to
“ESRI Shape File .JDA Export Format” on page 316 in the Appendix.
If you are in need of software that will view shape files, ArcExplorer is ESRI’s
free application that can be downloaded from the internet (http://www.esri.com/
software/arcexplorer/).
Export ESRI Shape Files:
1. From a field map, click Layers .
2. Click View for each layer that you want to export as an ESRI Shape file.
