In the second part I want you to use our GPS receivers to collect point data from around Lincoln Park.

Here are your instructions:

• Using a GPS like the ETrex is rather intuitive.  If you need it you can find a copy of the lengthy manual here.  You will likely be able to use it after a short instruction session in the Quad.
• We will be using an application that will run either as an extension inside ArcGIS or independently.  The application, developed at the Minnesota Department for Natural Resources, is DNRGarmin.  A short User Guide is also available for this application and there is a DNRGarmin Wiki as well.  Again it is very intuitive (at least I think so...).

The interface looks like this:

• When you go out to collect data, take a notebook or clipboard with you to record the attributes of the point features you are recording.
• After you have recorded waypoints for ten (10) different entities of a particular type (e.g. lightpoles, traffic signs, traffic lights, stop signs, etc.) in the vicinity of SAC and recorded at least two attributes (e.g. name, size, color, etc.) for these points, return to the Collaboratory and use the DNRGarmin application to download the waypoints and save them as a shapefile.

Waypoints can be download using the "Waypoint" menu. After downloading your screen will look something like this:

Select the points that you collected (shift-click) and then use the File - Save to.. - File - Type: ArcView shapefile (projected) option to save your shapefile into the Lab 2 folder.  You of course can download all of the waypoints collected and then delete the ones not yours in ArcGIS later.

Open your new GPS shapefile in your layout for part 2a.  Add the attributes you recorded in the field to your attribute table then label the points with one of your attributes.  Your Layout should include the aerial image/TIFF File, your new buildings and sidewalks, and your GPS points.  Print this and hand it in to finish the activity.  Due at end of class Wednesday 10-14.  Aces again!
