Overview for converting local plane coordinates to WGS84
问题 Let's say I have a small area mapped out using local planar coordinates in meters. e.g. A rectangular warehouse that's 300m x 450m. I use some GPS device to find the WGS 84 lat/lon of one corner of the warehouse. How can I project my plane coordinates onto the WGS 84 geoid to find the lat/lon values for the 3 other corners of the warehouse? I understand this is a complicated problem since values vary on different parts of the earth. Do I need to deal with finding some local coordinate system
