FYIO ... Altitude Testing
What is your altitude? You need to know this when working with the BMP085.
Since I have an airport 500 meters away on flat ground, I took their readings.
Elevation 902 feet.
Another way to check altitude use Google Earth or this link

Google Earth produced 896 feet.
Google Maps produced 896.363 feet
I used my handheld GPS and it showed 1000 feet?. <------ Do not use this reference!
GPS are NOT known by their precision altitude readings/calculations!
Sparkfun shows an error of 69 feet and I showed an error of 105 feet. <--- edited
I just added/installed a "very small" calibration offset in the software.
