Let me add a bit to this. GPS Coordinates are actually Latitude/Longitude Coordinates - in use looooong before GPS satellites (or any man-made satellite) ever existed. Latitude/Longitude (Lat/Lon) is a spherical coordinate system. UTM is spherical surface projection to a 2D flat surface. However, the Earth is not a perfect sphere. There are different models of the earth that each have varying accuracy in different regions of the Earth. And these models have also improved over time. The "Vincenty" formulas are used to go back and forth between the spherical model (Lat/Lon) and the flat model (Northing/Easting/Zone). The "Vincenty" formula are generalized to allow the use of different "ellipsoidial" models of the Earth using a "data set"of which WGS85 is the most common in use today, at least in the USA. The iPhone GPS chip provides location in Lat/Lon. A particular mapping program will locate a position on its maps based on the UTM data set the maps were created with. For example, Google uses WGS84 as did the old Microsoft Teraserver. I would expect that all map services located in the USA use WGS84. However, there are some map services with data that originates from older printed maps that used NAD27. I hope this helps a little.

That sounds real good but is a bit hypocritical. It is easy to believe that they present the "facts" when they present some thing that we don ' t know much about. But in the few cases when I have known a lot about the subject they presented, the facts were "their own". I'm not saying that they always present "their own facts" but I know some cases where they did. So saying You can chose your own opinion but not your own facts is .... OK, now I understand, it is not hypocritical - What they are saying is that while you can not chose your facts, they can.

I think the name of the rag says it all, even though that name is an oxymoron --- Popular Science --- Not real science or actual science, just popular science And they are THE ones to declare what is popular

The only reason to build consensus is to pick the dictator.

The FireMonkey DrawLine has an opacity parameter. When I pass that as 1.0, I would expect complete over write but I'm still getting some mix of the new and old values. What do I do to get complete opacue lines?

Is this a literal complaint about sarcasm or a sarcastic complaint about literalism or ... Reminds me of a joke about word use - During his normal boring lecture, a professor says 'In some languages, a double negative is a positive. And in others, it is a stronger negative. But in no language is a double positive a negative' And from the back of the lecture hall we hear 'Yeah, right' Sarcastically yours, Doug
