Trimble & Garmin1 data sets are direct dumps from the gps receivers:
  - Trimble.shp  - Collected with a Trimble Pro XR 12-channel differential receiver
  - Garmin1.shp -  Collected with a Garmin handheld 76 reciever, WAAS enabled.
     Agreement between the Garmin and the more precise Trimble is very good.
