Sample Data

Several sample data sets exist for this course. The main data set we will use is the GIS data for Pack Forest, described below.

Pack Forest Data

Most of the data sets used are from the Pack Forest GIS Database.

Where not otherwise specified, the data are in this Projection/Coordinate system:

Projection STATEPLANE
Zone 5626 (Washington State, South Zone)
Datum HPGN*
Units FEET
Spheroid GRS1980

* HPGN (High Precision GPS Network) is also known as HARN (High Accuracy Reference Network) or NAD83/91 (North American Datum of 1983, readjusted in 1991), but is similar to NAD83 for most purposes.

When asked for measurements, etc., it will be assumed that you are using the State Plane data, and that the storage and measurement units are feet, unless otherwise specified. This should make more sense to you when we cover projections.

Any data sets ending with other names (e.g., bound_utm) will have Projection/Coordinate systems signified by the file name.

All sample data for the course are located on the accompanying CD, in the directories packgis and esridata.

The esridata directory contains a number of data sets for the USA, Canada, Mexico, and the rest of the world. The data sets are from sources of very small scale and are generally good only for coarse-scale display or analysis.
